Description

A kind of south warm area plantation sweet cherry is taken shelter from rain, the method for sunshade and anti-bird

Technical field

The present invention relates to the warm area plantation in south sweet cherry management method.

Background technology

Cherry is the rose family (Rosaceae) Prunus cherry Subgenus, and the cherry kind in the world as fruit growing has sweet cherry, sour cherry tree, cherry and Nanking cherry.Cherry mainly sweet cherry (Prunus avium L.) and the cherry (Cerasus pseudocerasus) that China cultivates as business.Usually said sweet cherry refers to sweet cherry, also claims large cherry, is commonly called as car li son, and it is the Main way of current and even later cherry development.Sweet cherry fruit lovely luster, sparkling and crystal-clear beauty, red in agate, yellow as congealed fat, sweet flavor, fruit is rich in the multiple element such as sugar, protein, vitamin and calcium, iron, phosphorus, potassium, especially iron, and in every hectogram cherry, iron-holder reaches 5.9mg, occupy in fruit the first, deeply by consumers.

Compared with cherry, sweet cherry fruit is large, quality better, storage tolerance, is the Main way of current and even later cherry development.Sweet cherry fruit is short for growth cycle, morning in maturing stage, with cherry with the good reputation having ' all kinds of fruits first '.With growth in the living standard; sweet cherry has become high-grade fruit; price also increases to 20 ~ 40 yuan/kilogram; precocious area reaches 50 ~ 60 yuan/kilogram; and protecting field up to 70 ~ 100 yuan/kilogram; even higher, plantation sweet cherry becomes the plant husbandry of superelevation profit, is described as ' gold plant husbandry ', ' rising industry '.38.0 ten thousand hectares and 213.1 ten thousand tons have been reached respectively to world's sweet cherry gross areas in 2013 and output.As an efficient plant husbandry, the production area of world's sweet cherry and output linearly ascendant trend always.The sweet cherry of China's cultivation is mainly the national kinds such as Europe and North America, and in the northern area of China, performance is good.Due to larger market potential and higher planting benefit, China sweet cherry is produced and is also rapidly to the highland that cools such as Beijing, Hebei, Henan, Shaanxi, Gansu and cloud, expensive, river by places of production such as traditional Shandong, Liaoning and expands.While " tradition " Bohai Gulf area and " emerging " cool the flourish sweet cherry industry in highland, the introducing and planting that sweet cherry is also constantly attempted as the R&D institution of the In Middle And Lower Reaches of Changjiang Rivers such as Jiangsu, Zhejiang, Hunan, Shanghai and agribusiness in warm area, south, attempts sweet cherry industry south to advance.

Pujiang County is positioned in the middle part of Zhejiang Province, is located in north latitude 29 ° 27 ', east longitude 119 ° 53 ', belongs to subtropics monsoon climate.Average temperature of the whole year 16.6 DEG C, average annual precipitation 1412.2 millimeters.1996.2 hours sunshine of year.About 238 days frost-free season.The time of annual temperature below 7.2 DEG C is at 1100 hours.Generally 6, July set-in of plum rains, May, rainfall was also larger.As can be seen here, Pujiang plantation sweet cherry can meet the chilling requirement requirement of part kind, but it is too high to need to overcome summer temp, the unfavourable weather factor that rainfall is large.Rainfall is large, and summer temp is too high, and can cause sweet cherry excessive growth (only spending fruitless), flower early stage and florescence high temperature, be deteriorated by flood, dehiscent fruit, fruit quality, damage by disease and insect is multiple etc.If can cultivate successfully in Zhejiang, comparable northern outdoor cropping is gone on the market in advance, fruit maturation early, increase market supply phase of sweet cherry, save cost of transportation, price is high, has very high economic profit, more can develop city green agriculture and Sightseeing Orchard, the adjustment structure of rural undertaking, increases suburb farmers' income.And sweet cherry is early ripe, fruit development period is short, from setting to maturation, substantially need not go and buy Chinese medicine, and more easily reaches " green " or " organic " standard, can provide the freshest healthy fruit for Residents in Shanghai.

South, warm area, south warm regional rain heat same season, rainfall far exceedes needed for cherry, especially 5, June, hot and humid excessive rainfall not only caused maturing stage sweet cherry dehiscent fruit, and flower bud differentiation period just after fruit picking, the excessive growth of tree body is caused because of hot and humid, reduce the nutriment that may be used for flower bud differentiation, flower bud differentiation is insufficient, the directly lower annual production of impact.In rain heat same season, rainfall is excessive has a strong impact on the warm area plantation in south sweet cherry, and this problem is one of key reason causing the warm regional sweet cherry in south colored and unreal.

Summary of the invention

2, Introduced Varieties is in the performance of Pujiang County:

1) year performance of kind next year in Pujiang County is drawn:

Introduce a fine variety next year, draw phenophase and the result situation of 15 kinds, within 2010, be rudiment at the beginning of 3 months at Pujiang, contain flower by the end of March, ripe before and after most of kind mid-May.Wherein the percentage of fertile fruit of thunder Buddhist nun is the highest, is 64.3%; Next is that pioneer and Fan are short, reaches more than 48% respectively.The percentage of fertile fruit of beautiful morning, red Nanyang, Ukraine's series of products and Russian No. 1 is relatively low.After major part fruit is fully ripe, quality is good, and early the pol of large fruit reaches 18.5; And no-dehiscent fruit phenomenon occurs.Its chilling requirement of sweet cherry of Pujiang plantation in 2010 is in Shandong accumulation, so 2010 are only and can not represent the truth of sweet cherry at Pujiang as a reference.

2) Introduced Varieties was observed in the Pujiang County phenophase:

Within 2012, Introduced Varieties is many in rudiment in March, and mid or late March was bloomed at the beginning of 4 months, and mid or late May is ripe, and late November starts fallen leaves, and progresses into dormancy (table 2).Bloom and Cheng Shu Qi Zhuo than north sweet cherry want Zao.

Table 2, Pujiang County sweet cherry are introduced a fine variety the phenophase and are observed

Continued 2

Continued 2

3) Introduced Varieties is observed in Pujiang County breediness:

Output and commodity fruit rate

From table 3 sweet cherry result behavioral observation, each variety yield roughly can be divided into 3 classes: 1) Fan is short, and Sa meter Tuo, thunder Buddhist nun strain are produced and can be reached 20 ~ 40 jin/strain (Fig. 2 A ~ C); 2) red honey, Sang Tina, No. 1, Russia, early large fruit strain are produced and are reached 10 ~ 20 jin/strain, and wherein early large fruit output is unstable, best with 2014; 3) red light, beautiful early output relatively low (table 3).

Table 3: result behavioral observation introduced a fine variety by sweet cherry

One-tenth flower ability and the normal flower rate of observing Introduced Varieties in plantation have obvious difference simultaneously, and wherein short, the red honey of Fan becomes flower ability best, and flower amount is large, and trees are in full blossom (Fig. 2 E); Lei Nihua amount is moderate; Red light becomes flower ability the poorest.Therefore will take different cultivation steps in producing, Fan's short, red honey flower amount is large, need reduce invalid flower and improve fruiting rate further; Red light flower amount needs short flower at least, improves into colored power.

Deformed fruit rate statistics finds, wherein malformed fruit rate soprano is that Fan is short, reaches 29.7%, and red honey, red light, very good, Sa meter Tuo take second place in proper order.All the other kind malformed fruit rates are less, and more than 95% is commodity fruits.There are Shuangzi fruit, three son fruits, four sons fruit (Fig. 2 F) even in garden.Even can accept in the malformed fruit rate of present stage 30%, along with going deep into gradually of the sweet cherry marketization, abnormal rate height will become limiting factor.Therefore also need to consider this factor after output reaches requirement when Zhejiang plantation sweet cherry.

2.3.2 fruit quality

The sweet cherry fruit quality that Zhejiang produces is as shown in table 4, with same breed at northern grown place no significant difference.As long as reach a standard in Zhejiang sweet cherry economic production quantity visible, fruit quality temporarily can not become the factor of developmental limitation.

Table 4: Pujiang County sweet cherry is introduced a fine variety fruit quality and observed

Continued 4

Continued 4

3 are suitable for the recommendation of new cultivars in Pujiang development:

By this comprehensive observing of nearly 10 years, when especially having a regional development sweet cherry in similar habitat to Pujiang in Zhejiang area, Fan is short, the successful possibility of kind such as Sa meter Tuo, Lei Ni and red honey is larger.They at the result photo of Pujiang as Fig. 2.

4, southern sweet cherry rootstock is on the impact of sweet cherry variety:

The stock that sweet cherry is widely used has folium isatidis, Gisela, ZY-1, horse Harry, examines top grade etc.Wherein:

1). folium isatidis dungarunga or shrub.It is the excellent sweet cherry vigorous stock that Shandong Yantai City selects from cherry.But the tree crown that the sweet cherry tree crown of grafting on Willowleaf Hygrophila Herb cherry does stock compared with horse Harry is little.Stronger with most sweet cherry variety grafting affinity.Hair root is more flourishing, and adaptability is comparatively strong, and anti-crown gall, drought resistance are general, intolerant to waterlogging.After grafting sweet cherry variety, tree body is taller and bigger, and Root Distribution is shallow, meets strong wind and easily lodges.After grafting strain field planting 3 years start result, enter the full bearing period and need 6 ~ 7 years.Main employing is tillered, propagation by layering.Be suitable for growing in sandy loam or gravelly loam, when heavy soil grows, the easy gummosis of trees in richful production period grafting part, also has " bound feet " phenomenon.Be 2.5 ~ 3 × 4m with the seeding row spacing that folium isatidis makes stock suitable, i.e. every mu of 55 ~ 66 strains of planting.

2), the sweet cherry tree body size of GiselaNo.5 grafting on " GiselaNo.5 " stock be only 45% of " campstool moral " stock, and tree body is opened a business, and branch base angle is large, saves labour, equipment, chemicals, and is convenient to bookkeeping.Very early bearing, 2-3 is raw starts result, usual 4-7 raw 5-15Kg/ strain, anti-prunus necrotic ring spot virus (PNRSV) and prune dwarf virus (PDV).Soil suitability is wide, and on clayed ground, performance is good.Sprout tillers is few, admittedly functional, but still need support, winter resistance to-30 DEG C of low temperature.But at very dead soil with natural precipitation is few and under bad cultivation condition, shoot growth amount is little, fruit diminishes, easy early ageing.Planting density is: every mu of 84 ~ 111 strains of planting, seeding row spacing is 2 × 3 ~ 4m.

After these stocks of project first preanalysis sweet cherry, folium isatidis and GiselaNo.5 is selected to carry out comparative trial.The growth potential of experimental observation grafting some kinds on folium isatidis and GiselaNo.5 and result quantities, the sweet cherry variety amount of growth grafted on folium isatidis is far longer than the amount of growth grafted on GiselaNo.5, and flower amount is few, and bud does not enrich, and therefore fruiting rate is low.The kind growth grafted on GiselaNo.5 is just suitable, and flower amount is large, and bud enriches, and fruiting rate is high.But Sang Tina is stock with GiselaNo.5, then amount of growth is too small, and growing way is weak, is not enough to meet produce; Be that then growth potential is better for stock with folium isatidis, this may be relatively weak relevant with the growth potential of Sang Tina itself.。

Zhejiang high temperature and rainy, rich water is sufficient, and trunk infusion growth is easily excessive, and same kind can grow to 2.6 meters at the bud seedling in Zhejiang one season, and the same kind bud seedling in Shandong grows to 1.5 ~ 1.8 meters, as seen in the sweet cherry amount of growth of Zhejiang growth considerably beyond Shandong.As can be seen here, sweet cherry is large in Zhejiang tree height, be difficult to into colored, and management inconvenience, Dwarf Effect on Dwarf must be selected good in Zhejiang area, the stock that Flood resistance is strong, concerning most of kind, select Gisela to be that stock is better, make full use of its dwarfing ability, reduce growth potential, finally reach balance tree vigo(u)r, short effect of spending short fruit.Zhejiang area wind-force is large and have and often have typhoon phenomenon, plants experimentally region bracing wire need be coordinated to prevent the shortcoming of GiselaNo.5 property deficiency admittedly at us.But use folium isatidis to be stock for Sang Tina suggestion, this may be not relevant by force with the growth potential of Sang Tina own.

For south, warm area, south warm regional rain heat same season, rainfall far exceedes needed for cherry, especially 5, June, hot and humid excessive rainfall not only caused maturing stage sweet cherry dehiscent fruit, and flower bud differentiation period just after fruit picking, the excessive growth of tree body is caused because of hot and humid, reduce the nutriment that may be used for flower bud differentiation, flower bud differentiation is insufficient, the directly lower annual production of impact.In rain heat same season, rainfall is excessive has a strong impact on the warm area plantation in south sweet cherry, and this problem is one of key reason causing the warm regional sweet cherry in south colored and unreal.

Have developed that a kind of south warm area plantation sweet cherry is taken shelter from rain, the method for sunshade and anti-bird for this reason.As shown in Figure 1, the cement post 7 that the frame that method of the present invention adopts is the arrangement of multirow longitudinal separation, bottom is embedded in underground, line-spacing is determined according to plantation nursery stock, the high 0.4m in field planting ridge 8, wide 1.5m, seeding row spacing is 2m × 4m, digs the drain ditch 9 of dark, wide each 0.2m in the ranks, the column pull-down line earth anchorage of surrounding, C20 cement is built, concrete column is high 3.8 meters, post cross section 8 × 10 centimetres, enter 0.5 meter, ground, the added steel pipe 4 having diameter 25 of cement post 7 of often going, the arch bar 2 of shape of drawing a bow under erection two ends, every 2 longitudinal cement post 7 overhead forms ceiling frame, 2 arch bar 2 spacing 1 meter, the two ends of bend pipe are positioned on the steel pipe 4 of frame shoulder, longitudinal duplex pull rod is fixedly connected, longitudinally plastic foil 1 is equipped with on ceiling frame, hide whole ceiling frame, the outer film-pressing line of film is fixed on both sides steel strand wires and arch bar 2, the both sides of described plastic foil 1 longitudinal direction are connected with roll bar, roll bar is connected with film-coiling device, plastic foil 1 is wound in roll bar by film-coiling device, plastic foil 1 can be rolled onto 1/2 place of ceiling frame with roll bar, the opening and closing degree of plastic foil 1 on ceiling frame is controlled by film-coiling device, when need take shelter from rain, plastic foil 1 placed by frame, need in same posture, to put sunshade net 3 during sunshade, bottom ceiling frame, be provided with draw-in groove 5, the method comprises the following steps: 1) the 3rd year start overlay film, in spending at the beginning of mid-March before, detain canopy, according to weather temperature at that time, front temperature must be spent more than 30 DEG C, then after spending, detain canopy when detaining canopy, late June lid sunshade net 3, mid-September daily mean temperature to take shelter from rain film and sunshade net 3 25 DEG C of removals, the light transmittance of sunshade net 3 is with 30 ~ 35%, and during button canopy, canopy internal ratio canopy is outer low 1 ~ 3 DEG C, during sunshade, temperature of shed is outer than canopy low 1 ~ 3 DEG C, rainy season takes shelter from rain, 2) when needing anti-bird before fruit colour-change period, bird prevention net is vertical from the top down, is connected between canopy with canopy with bird prevention net is airtight, by whole processing surrounding covering, prevents bird from entering.

The committed step of sweet cherry Early postoperative management method of the present invention: ridging; Fall planting; Treelet by cultivate tree-like centered by; The heavy summer cuts, and the light winter cuts, and draws branch to carve bud, and balance tree vigo(u)r controls tree crown and reaches result area fast.

One, ridging: field planting ridge height 0.4m, wide 1.5m, seeding row spacing is 2m × 4m, digs the drain ditch of dark, wide each 0.2m in the ranks.Compare with not ridging with row spacing 4 meters, wide 1.5 meters obviously will get well.Similar to not ridging of wide 4 meters, can not reach the effect reducing underground water, impeded drainage.(this is one of place different from north)

Two, field planting: treelet adopts fall planting or spring planting.Advise southern warm area with fall planting as well.Every mu of application of organic fertilizers 2000kg before field planting.The anti-crown gall of root (this is for south also outbalance, and southern soil property is glued, and easily produces crown gall) is stained with the K84 of 10 times before field planting.Pour water after ridging field planting heavy real, and cover black mulch film moisture-keeping.

Three, shaping and pruning:

Shaping:

Warm regional sweet cherry amount of growth is large, should use spindle in field.The tree-like growth potential that fully can adjust branch of spindle, reduce water sprout, branch need draw branch amount obviously to reduce.The height of tree be shaped controls at below 2.5m, hat 2.5 ~ 3m.Natural open centre shape branch is too upright, and growth potential is excessively prosperous, not only causes the later stage to draw a workload large, time-consumingly takes a lot of work, and is unfavorable for flower_bud formation.

Spindle Shu Tiju center is done.Treelet is based on sparse branching and carve bud, cultivates side shoot and fruit bearing shoot, forms standard as early as possible tree-like.Plantation First Year fall leaves in the winter time after before rudiment in spring in tree body mobile jib overhead 60cm place fixed pole, clip lower first bud distance clip about 1.5cm stays full bud, and strong for pumping prosperous branch is done trunk elongated shoot by it.2 buds under this bud are erased; To impel the sprouting of other bud.Branch is sent out below after the beginning of spring.Stay 4 ~ 5, form the ground floor of tree body.Second Year chooses every about 10cm below mobile jib that orientation staggers, full 3 buds, and above the bud of middle choosing, 1cm is in the budding period and carries out bud at quarter, and the degree of depth of carving bud will reach xylem, inspires major branch.Carving bud width is the half of branch thick.Form the second layer of tree body.After determining to do, clip will wax, paint or animal fat.

If directly plant seedlings person, then in mobile jib overhead about 1 meter place's fixed pole, under clip, full bud is stayed at 2cm place, and 2 buds under this bud will be erased; Stay the 4th bud, then smear 3 buds, choose that orientation staggers, full 3 buds after staying 1 bud every about 10cm, above the bud of middle choosing, 1cm is in the budding period and carries out bud at quarter, and the degree of depth of carving bud will reach xylem, inspires major branch, and carving bud width is the half of branch thick.Directly form two layers of major branch in this approach.

If base portion, more than the seedling of 1 major branch, the most important thing is selected mobile jib, select enriching shoot, vertical angle large and distribution branch comparatively placed in the middle is left mobile jib, the processing mode of mobile jib is the same.Other branch is according to following principle process: when branch is many, and competitive branch stays 1 ~ 2 bud cutting back at base portion; When competitive branch is few, competitive branch is evened up, when to draw, allow the balanced occupancy level space of branch as far as possible, can along shoot growth direction.Can cut under the above 60cm place of branch, lower first bud of clip is apart from more than clip 1.5cm, and strong for germinating prosperous branch is done trunk elongated shoot by the first bud; Bud below lower first bud of clip within 10cm will be erased; Choose that orientation staggers, full 3 buds more in its lower section every about 10cm, above the bud of middle choosing, 1cm is in the budding period and carries out bud at quarter, and the degree of depth of carving bud will reach xylem, inspires major branch.

Prune:

Because southern Growth status amount is obviously greater than the north, treelet carries out the summer pruning at the center that is shaped as, and treelet summer pruning, mainly for controlling the prosperous length of branch, increases branch sum of series branch amount, promotes that branch class transforms, accelerate to expand tree crown.Because the raw branch amount in south is large, therefore summer pruning workload is large, wants regular and irregularly carry out from April to August.The main method of summer pruning has angle of release, pinching, top clipping, turns round the tip, except sprouting, drawing branch etc.Branch is wherein drawn to be the key measures that south warm area plantation sweet cherry is pruned.Draw branch just can carry out after the beginning of spring.Must draw along the bearing of trend of branch when to draw, angle 80 ~ 90 degree.Branch is drawn to play balance tree vigo(u)r, adjustment shoot growth direction and space.

The pruning technique of another one key carves bud.Rudiment in spring carves bud in first about 15 days, inspires branch and bouquet shape brachyplast, bud at the quarter position of back bud, lateral bud and lower bud and mode difference.Back bud carves bud after bud, reduces nutrient, impels into bud.If back bud is carved bud and very easily formed water sprout before bud, not only can not play and promote into colored effect, reduce nutrient on the contrary.Lateral bud and lower bud carve bud before having bud, inspire branch.North carves bud before bud, and object becomes branch in order to short bud.Other as angle of release from field planting May then to November, the upper mitogenetic young sprout toothpick growing into about 20cm is done to center or small bamboo spike carries out support branch the first transaction of a day's business base angle.Sprig grows to about 10cm pinching or turns round the tip, to grow after 2 ~ 3 leaves priming leaf repeatedly.

Four, fertilising and water management (conventional steps):

The first three years plantation, to be grown to master, is therefore attached most importance to base manure in autumn in fertilising, and autumn, base manure was early executed as well, how to carry out in October.Fertilizer, based on fertilizer, can mix a small amount of nitrogen fertilizer.After base manure, as run into arid, foot be watered and irrigate, soil moisture conservation after watering, will be done well, strengthen the ability that tree body is survived the winter.Growing season repeatedly can supplement fertilizer on a small quantity on a small quantity.The rainfall is plentiful in south, and except extreme weather, treelet does not need additionally to pour water.

Five, the extermination of disease and insect pest (conventional steps):

Resting stage at the beginning of late November to 2 month, trunk whitewashing (formula rate of white-out agent: quicklime 10 kilograms, Cosan 1 kilogram, salt 1 kilogram, vegetable oil 0.1 kilogram, 20 kilograms, water) and clear garden work (the sick fruit of removing, sick leaf, sick branch are taken out of buried outside garden or burn) to be carried out early, spray lime sulfur after tree body drop leaf.

Spray 5 Baume degrees lime sulfurs before early Febuary rudiment, serious orchard occurs coccid should spray 40% methidathion missible oil 1500 times.Mid-February to the early March budding period scrapes control coating to rot, dry rot scab, and as found, note dry hole is found in the harm such as longicorn, with the hole of the blocking branch-trunk insect such as poison label, kills off the insect pests.Should note strengthening the generation (spray the clean or phoxim baythion of the cockchafer of 1500 times, and with black light lamp or sugar-vinegar liquid trapping) of big gourdshaped weevil first of control apple rain beetle, east chafer and young garden after germination to June.Note the leaf diseases such as shothole disease, leaf spot (thiophanate methyl of the mancozeb of 800 times or 1500 times is used alternatingly) to August from mid-April, prevent and treat red neck longicorn with the worm channel on the blocking limbs such as poison label.Gummosis all will be prevented and treated whole vegetative period, is coated with 5 Baume degrees lime sulfurs+500 times of carbendazim or the spirit of foliage-spray peach gummosis, finds at any time to prevent and treat at any time in vegetative period after striking off glue.Mid-June to August, young sprout vigorous period strengthened control leaf diseases.Note the generation observing the damage by disease and insect such as telson moth, boat-shaped caterpillar, oriental fruit moth, shothole disease, brown rot, carry out artificial control or medical treatment according to Harm.

The vegetative storage phase in November protects the work that blade is this phase most important, most critical, so want attention control early defoliation disease.

The management method of south plantation sweet cherry Cheng Shu is as follows.

One, take shelter from rain, sunshade adds anti-bird

For south, warm area, south warm regional rain heat same season, rainfall far exceedes needed for cherry, especially 5, June, hot and humid excessive rainfall not only caused maturing stage sweet cherry dehiscent fruit, and flower bud differentiation period just after fruit picking, the excessive growth of tree body is caused because of hot and humid, reduce the nutriment that may be used for flower bud differentiation, flower bud differentiation is insufficient, directly affects lower annual production and is easy to produce malformed fruit.In rain heat same season, rainfall is excessive has a strong impact on the warm area plantation in south sweet cherry, and this problem is one of key reason causing the warm regional sweet cherry in south colored and unreal.The key problem in technology that south warm area plantation sweet cherry is taken shelter from rain, sunshade is south plantation sweet cherry success.

South started overlay film in the 3rd year, before Yu Chuhua (mid-March) detain canopy, when canopy (button according to weather temperature at that time, front temperature must be spent more than 30 DEG C, then after spending, detain canopy), late June lid sunshade net.Mid-September daily mean temperature to take shelter from rain film and sunshade net 25 DEG C of removals.Lid sunshade net can not early than late June, otherwise the sugar content of fruit is low, short sweetness; The light transmittance of sunshade net is best with 30 ~ 35%.During button canopy, canopy internal ratio canopy is outer low 1 ~ 3 DEG C, effectively reduces summer high temperature, promotes flower_bud formation, reduce malformed fruit, and postpone fallen leaves.Postpone fallen leaves and have very important effect (postpone fallen leaves, leaf nutrition backflow is many, is conducive to flower bud differentiation in the coming year) to flower bud differentiation in the 2nd year; During sunshade, temperature of shed is outer than canopy low 1 ~ 3 DEG C.Rainy season takes shelter from rain, and can reduce Cracking fruit 70%.

When needing anti-bird before fruit colour-change period, bird prevention net is vertical from the top down, is connected between canopy with canopy with bird prevention net is airtight, by whole processing surrounding covering, prevents bird from entering.

Two, water management (different from treelet, also different from northern bearing tree in addition):

Cherry root system respiratory capacity is large, distributes more shallow, be distributed in the soil layer of 15-40cm more in soil, thus show neither drought-enduring also intolerant to waterlogging need water feature.The water management of sweet cherry bearing tree is very important, and we think that water management will be divided into three directions: one is pour water; Two is control water; Three is prevention waterloggings.Wherein:

1) pouring water: will water after general fertilising, rich water therefore can being taked with filling with.Watering before spending on a small quantity in sweet cherry garden, prevents Snow coverage.Mid-April to late April waters short fruit water, and before Xie Huahou to fruit maturation, during this, sweet cherry growth is the most vigorous, the most responsive to the supply of moisture, if young fruit early ageing and shedding will occur water deficient.Fructescence at the beginning of mid-May to 6 month keeps soil moisture content 60% ~ 80%, is sure not overdrying or excessively wet, prevents dehiscent fruit.Pouring water after fruit harvesting should be little unsuitable large, with meadow bog skin as well.November pours water time arid especially (different from the north, the north needs the embedding in resting stage to freeze water).

2) control water: Zhejiang Province's rainfall is 2 ~ 3 times of sweet cherry suitable growth district, therefore control the committed step that water is the plantation of southern sweet cherry success.Florescence takes shelter from rain, and reduces blossom rot, increases pollination; The fruit phase takes shelter from rain, and reduces dehiscent fruit; Control water (early June is to early July) after fruit picking, increase bud amount, make bud satiation, for high yield in next year lays the first stone, effectively control nourishing and growing of young sprout simultaneously, promote reproductive growth, be beneficial to Early Paleozoic strata.

3) drainage waterlogging prevention is wanted whole vegetative period.Especially more drainage waterlogging prevention will be carried out during young sprout vigorous period Used in Rainy Seasons of Southern Cities in mid-June to August.

Three, shaping and pruning:

Bearing tree adopts spindle, and mobile jib height is not less than 80cm, and tree crown controls at below 2.5m, accomplishes the low hat of high level cadre.Trees in richful production period, with cultivation, rejuvenation, renewal fruit bearing shoot, under pressing down upper urging, prevents strong up and weak down or upper weak lower strong tree vigo(u)r, regulate the quantity of bud and be distributed as center, formed with the basic skills of fruit layer balance tree vigo(u)r, sensible load, result too much easily causes short fruit tree withered.Balance tree vigo(u)r mainly adopts suitable stock and combines and draws branch.Branch is drawn to be the key measures that south warm area plantation sweet cherry is pruned.The branch of sweet cherry has the habit of upright growth, the branch of evening up spring, can come back again summer and upwards grow, therefore should note evening up major branch and side shoot at any time, the ventilation and penetrating light of thorax in such guarantee.For water sprout at the drop-down branch of the situation of having living space, draw the angle 80 ~ 90 degree of branch, must along the bearing of trend technology of branch when to draw.Bud picking or pinching when space.Sprig grows to about 10cm pinching or turns round the tip, to grow after 2 ~ 3 leaves priming leaf repeatedly.On master branch, the back branch of pumping should carry out when growing to about 30cm turning round the tip, or removes, in order to avoid upset tree-like.

Play balance tree vigo(u)r, adjustment shoot growth direction and space, the pruning technique of another key carves bud.Rudiment in spring carves bud in first about 15 days, inspires branch and bouquet shape brachyplast.Except extending head, continuous pinching is carried out to the branch inspired, promotes flower bud differentiation.Bud at the quarter position of back bud, lateral bud and lower bud and mode difference.Back bud carves bud after bud, reduces nutrient, impels into bud.If back bud carves bud before bud, very easily form water sprout, not only can not play and promote into colored effect, reduce nutrient on the contrary.Lateral bud and lower bud carve bud before bud, inspire branch.(north carves bud before bud, and object becomes branch in order to short bud.) before rudiment for saving trunk infusion, bud can be removed 1/2nd (this is one of place different from north), to promote that the later stage yields positive results.The raw branch amount in south is large, and therefore summer pruning workload is large, often irregularly to carry out.

Four, fertilizing management (different from treelet, also different from northern bearing tree in addition):

The warm regional sweet cherry bearing tree in south is attached most importance to base manure autumn, and base manure is early executed as well, how to carry out in October.Fertilizer, based on fertilizer, can mix a small amount of nitrogen fertilizer.After basal dressing, as run into arid, foot be watered and irrigate, soil moisture conservation after watering, will be done well, strengthen the ability that tree body is survived the winter.Growing season is then distinguished in the following ways:

1) topdress before spending, adopt radial canal, the every strain of trees in richful production period imposes composite fertilizer 1 ~ 2 kilogram, or night soil 30 kilograms, or 1 ~ 1.5 kilogram, urea, or 2 ~ 2.5 kilograms, ammonium sulfate, water before watering flowers after fertilising.

2) florescence spray leaf fertilizer 2 ~ 3 times.

3) the early and middle ten days flower_bud formation phase in June, topdress after carrying out fruit picking, best with quick-acting fertilizer, ditch or dig and spread manuer in holes, water after fertilising.

Five, the extermination of disease and insect pest (conventional steps, but because of southern rainwater many, soil stickiness is large, more will pay attention to the control of the brown rot of gummosis, root knot and florescence and fruit phase):

1) resting stage at the beginning of late November to 2 month, trunk whitewashing (formula rate of white-out agent: quicklime 10 kilograms, Cosan 1 kilogram, salt 1 kilogram, vegetable oil 0.1 kilogram, 20 kilograms, water) and clear garden work (the sick fruit of removing, sick leaf, sick branch are taken out of buried outside garden or burn) to be carried out early, spray lime sulfur after tree body drop leaf.

2) spray 5 Baume degrees lime sulfurs before early Febuary rudiment, serious orchard occurs coccid should spray 40% methidathion missible oil 1500 times.Mid-February to the early March budding period scrapes control coating to rot, dry rot scab, and as found, note dry hole is found in the harm such as longicorn, with the hole of the blocking branch-trunk insect such as poison label, kills off the insect pests.Should note strengthening the generation (spray the clean or phoxim baythion of the cockchafer of 1500 times, and with black light lamp or sugar-vinegar liquid trapping) of big gourdshaped weevil first of control apple rain beetle, east chafer and young garden after germination to June.

3) note the leaf diseases such as shothole disease, leaf spot (thiophanate methyl of the mancozeb of 800 times or 1500 times is used alternatingly) to August from mid-April, prevent and treat red neck longicorn with the worm channel on the blocking limbs such as poison label.Mid-June to August, young sprout vigorous period strengthened control leaf diseases.Note the generation observing the damage by disease and insect such as telson moth, boat-shaped caterpillar, oriental fruit moth, shothole disease, brown rot, carry out artificial control or medical treatment according to Harm.

4) the vegetative storage phase in November protects blade is the most important work of this phase, so want attention control early defoliation disease.

5) control of gummosis, root knot is carried out.Gummosis all will be prevented and treated whole vegetative period, is coated with 5 Baume degrees lime sulfurs+500 times of carbendazim or the spirit of foliage-spray peach gummosis, finds at any time to prevent and treat at any time in vegetative period after striking off glue.Carry out the control of root knot, one finds at once with K84 process.

6) brown rot is carried out: before spending and spend and respectively spray Tuzet, carbendazim, a mancozeb temple bactericide afterwards.Young fruit period sprays a bactericide again.

Six, other management:

Except above administrative skill, sweet cherry of growing up need put honeybee at the florescence increases pollination, flower and fruit thinning (present southern warm area can flower thinning, need not fruit thinning).
