Abstract

The present invention belongs to the technical field of afforestation, which particularly relates to a summer tree transplanting method in drought and half-drought regions. The present invention which is characterized in that plant hormone is used for prompting nursery stocks in a sleep state has the following steps: nursery stocks which need to be transplanted are selected and are not watered for 18 to 20 days, plant growth hormone medicament are sprinkled to prompt the nursery stocks in a long-term sleep state when air temperature rise to more than 25 DEG C., and a drought phenomenon occurs on the plants; after the nursery stocks sleep, the nursery stocks with soil are lifted quickly by the book, and the soil lump is packaged by plastic cloth; after planted, the nursery stocks are watered by ferrous sulfate solution of which the concentration is 0.1 %, KH2PO3 solution of which the concentration is 5% is sprinkled on leaf surfaces for one to three times to remove the induction of the growth hormone to the sleep of the plants. In the present invention, May, June and July are selected to transplant trees in close time, so that the trees successfully planted have sufficient chances of growth and development when a rainy season comes, and the lignification degree of new tips is raised. After a rainy season, the plants have sufficient physiological resources to live through long drought and cold seasons, and the survival rate and the preservation rate of afforestation are raised.

Description

Summer the trees trasplanting method

Technical field

The invention belongs to the afforestation technical field, be specifically related to a kind of arid, the semiarid zone forest planting method in summer.

Background technology:

In NORTHWEST CHINA portion area, because the serious restriction of natural conditions, the seasonality of afforestation is very strong, and traditional planting-season is spring, Qiu Liangji, and whenabouts be the late April of late October to the second year in every year.Just the winter dormancy from plant begins to end to the rudiment in spring.Be precipitation minimum period among this area 1 year this period, accounts for below 20% of annual precipitation.Windy, dry over a long time weather conditions, this is subjected to more serious damage with injured sapling to make the transplanting process.In the task-set of in addition planting trees, management workload is big, can only low level management, and growth potential is contained that survival rate is low.Interim to rainy season, the growth potential of most plants is difficult to rapid recovery, tree vigo(u)r a little less than, the storage rate in the coming year is low.This also is a major reason of current appearance " plant tree every year and lose tree, the difficulty of afforesting is for many years grown into forest ".Some is local for by inspecting for acceptance or other purpose in recent years, takes the way of after-culture in rainy season.Do the afforestation campaign of some surprises.The seedling of planting trees, because the autumn growth degree of lignification is low, and ground temperature begins to descend, root system stops growing substantially.After rainy season, it is again arid, the cold season of nearly 6 wheat harvesting periods.The physiological drought of trees is serious, survives, the storage rate all effected.

Five, six, the July, be the forbidden zone of the Northwest's tradition afforestation.Because this period, temperature raises rapidly, reaches as high as more than 35 ℃.Precipitation is still low, and is dry, hot; Changes in temperature are alternately frequent, and plant metabolism is vigorous.Existing " naked method of transplanting trees " is difficult to guarantee that the complete sum of root normally absorbs the function of moisture and nutrient.Especially at migration process, the water metabolism balance of sapling is upset suddenly, the physiology natural reaction of stimulating plant, and the leaf base absciss layer forms rapidly, and a large amount of leaves come off one after another, and plant survival is difficulty more.

Summary of the invention

The invention solves the technical problem of the afforestation in arid, semiarid zone summer, a kind of survival rate, trees trasplanting method that storage rate is high are provided.

The present invention realizes that by following method summer, the trees trasplanting method is characterized in that using plant hormone to impel nursery stock to enter resting state, and its method step is as follows:

Step 1, nursery stock is handled, and chooses the nursery stock that needs transplanting, does not water in 18-20 days, treat that temperature is increased to more than 25 ℃, arid appears in plant, promptly high noon leaf roll, the obfuscation of leaf coloured light pool, spray plant growth steroids medicament promotes the resting state that nursery stock enters the long period;

Step 2, lifting after the nursery stock dormancy, is with native lifting rapidly routinely, and the soil diameter that sticks together must not be preced with 2/3rds of the width of cloth less than nursery stock;

Step 3 is packed Tu Tuo with Polypropylence Sheet or woven; The fragmentation even soil sticks together, female soil also are not easy to miss, the whole mulch landfills of fragmentary female soil when planting; And packaging material are reusable.

Step 4, the ferrous sulfate aqueous solution with 0.1% concentration after planting waters, and is 5% KH with concentration ₂PO ₃Spray solution blade face 1-3 time is to remove the inducing action of somatotropin to plant dormancy.

Auxin class medicament of the present invention is fulvic acid, fulvic acid and ethene mixed liquor, abscisic acid, class abscisic acid, epoxycyclohexane derivative, the plain steroidal of rape, and these plant hormones all have the inducing plant dormancy, suppress rising effect.

The present invention is chosen in five, six, this so-called taboo phase transplanting of planting trees of July, helps planting the trees that survive when arrive rainy season, and the chance of growing is fully arranged, and the degree of lignification of young sprout improves.After rainy season, plant has enough physiology resources, spends the season of very long arid, cold, improves the survival rate and the storage rate of afforestation.

Auxin class medicament of the present invention is characterized in that the computational methods of working concentration are: X=n/ (Y-a)+m

X: the desirable consumption concentration of expression plant hormone

Y: the maximum temperature of environment is transplanted in expression

M: minimum effective inhibition concentration of expression plant hormone

N: the minimum lethal concentration or the highest produce effects concentration of expression plant hormone

A: the most suitable temperature of expression plant growing

Advantage of the present invention and beneficial effect:

The present invention proposes a kind of brand-new afforestation theory, plants trees to overcome with existing method---the shortcoming that season is short, survive difficulty, storage rate is low.Increase a significant opportunity of arid, semiarid zone five, six, July afforestation.And method is simple, and is theoretical clear and definite understandable, and is not subjected to the restriction of traditional tree-planting method.Improve the storage rate of afforestation, reduce overlapping investment, reduce the waste of nursery stock resource, accelerate under the various environment such as city, rural area, scenic area greening, beautify process.

In arid, hot season, utilize method of the present invention to plant trees through test, except that indivedual seeds, survival rate, storage rate all can reach more than 90%; Existing other method survival rate, storage rate are all difficult breaks through 60%.In planting season of routine, plant trees with existing method, survival rate can reach 90%, storage rate is difficult to break through 70%.
