Specific embodiment

Make detail description with reference to the growth characteristics of Ilex purpurea Hassk.[I.chinensis Sims pinaster.

1st, hold in good time temperature: four seasons Lignum Pini Nodi is strong positive seeds it is desirable to the weather conditions of warm and moist, in areal area Average temperature of the whole year is 13 to 22 degrees Celsius, and in high altitude localitiess, due to low temperature, wind is big, is the Ilex purpurea Hassk.[I.chinensis Sims pine vertical distribution upper limit Key constraints, therefore height above sea level are how below 1400 meters.

2nd, hold moisture Control: the drought-resistant feature of four seasons Lignum Pini Nodi, show that root system has very strong hydrotropism, be grown in xerosol Four seasons Lignum Pini Nodi in layer, its root system stretches to depths and absorbs moisture, forms powerful vertical root system.But, if excessively arid, Rainwater area very little, is but not suitable for planting four seasons Lignum Pini Nodi, and in general, four seasons Lignum Pini Nodi is suitable for being planted in annual precipitation 600 milli Area more than rice.

3rd, make full use of illumination: being grown in hills and low mountain zone four seasons Lignum Pini Nodi more, different by illumination, grow also variant, position The growth of Yu Nanpo is best, north slope worst, so, four seasons Lignum Pini Nodi is suitable for the local plantation on the sunny side.

4th, the selection of nursery lot: want to cultivate Seedling, first have to choose nursery lot, enjoyed light according to Ilex purpurea Hassk.[I.chinensis Sims loose seedling, flood afraid of water Feature, nursery should select flat in physical features, or slightly tilts it is easy to the hillside fields of draining, shade in the no big tree of surrounding or mountain peak, sunlight Sufficient.

(1) edaphic condition selects: soil should select slightly acidic sandy loam or light clay loam.In addition, vegetable of must not choosing seeds, Melon, Cotton Gossypii, the soil of the coniferous specieses such as Rhizoma Solani tuber osi or Lignum seu Ramulus Cunninghamiae Lanceolatae, the harm of prevention infection damping-off and subterranean pest-insect.

(2) arable land site preparation reason: careful site preparation is the material base of nurturing staff.Nursery lot, before the arriving of winter the previous year, is used Plough is turned over, and breaks thick and solid soil layer, increases the breathability of soil, general 16 to 18 centimetres of tilling depth.

(3) seedbed construction: arrive when spring, broadcast it is possible to build seedbed prepares when temperature stabilization is more than 15 degrees Celsius Kind, seedbed direction is mostly different according to landform, but preferably north-south.1.6 meters of the width in seedbed is advisable, and length is according to plot Fixed, changeable.Along the straight line drainage trenching drawing, the purpose in gutter is exactly loose ventilative, the row in order to keep soil General 18 centimetres of the depth in ditch.After gutter is dug, thin for the Rhizoma Panacis Japonici in seedbed is raked, after raking the soil level, on soil Panasonic is real, loose soil above, and soil moisture conservation ventilate, is conducive to emerging, soil under reality, and seed is contacted closely with soil, has Germinate and bundle under root system beneficial to water suction.Soil in seedbed is raked after harrow broken, with spade the topsoil of 1.5 centimetres of upper soll layer Dig out, be individually placed to the both sides in seedbed, along the uniform heap in the both sides youngster in heaps in seedbed, dig out this layer of table soil coming, for sowing Earthing afterwards.

(4) rationally with fertilizer: need to use sufficient base manure after plow harrow, with geography of fostering and apply fertilizer.Fertilising can use compound potassium sulfate fertilizer, because For the optimal soil of four seasons Lignum Pini Nodi be ph value 6 6.5 faintly acid soil, if your soil is neutral soil, every mu 25 kilograms of improved soils of compound potassium sulfate fertilizer can be used；If the ph value of soil is more than 7.5, in alkalescence, then will Using 25 kilograms of improved soils of compound potassium sulfate fertilizer.If the growth that the ph value of soil does not meet four seasons Lignum Pini Nodi requires, that is, enable Enough emerge, seedling also will not be healthy and strong.

(5) deinsectization sterilization: before making bed, in order to prevent damping-off and subterranean pest-insect, soil disinfection should be carried out.Generally every mu use 3.5 kilograms of 25% carbendazol wettable powder.Because the usage amount of carbendazol wettable powder is smaller, if be directly spread to Medicament can be caused uneven inside soil, so, carbendazol wettable powder can be mixed thoroughly with fine earth, equably be sprinkling upon seedbed In.

(6) pour bottom water: after seedbed is put in order, soil moisture conservation of watering.Common people also pour bottom water watering to be called before sowing, its mesh Be for seed provide germinate required for moisture, once water and must irrigate, be poured onto and the seedbed soil of 16 cm thicks will be allowed to fill Divide and absorb moisture and reach saturation.It is impossible to sow at once after having poured water, the water in seedbed to be waited all penetrates into After in ground, just can sow.

(7) seed choosing is broadcast: artificial culture four seasons Lignum Pini Nodi is it is necessary to use the fresh seeds of autumn the previous year harvesting, every mu of amount of application 2.5 kilogram.Before sowing, first the seed of four seasons Lignum Pini Nodi is soaked 2.5 hours in 40 degrees Celsius of warm water, so that seed is fully inhaled Water expands, and is conducive to emerging.The seed floating on the surface is skimmed, because these seeds are immature, finally remaining seed Pull out.In order that seed be distributed in seedbed more uniform, can by seed and fine earth mix even after sow again.Seed is in storage fortune During defeated, more or less can carry various pathogenic bacterias, preferably carry out seed disinfection before planting.Can be by methyl Tobe The medicines such as Tianjin spread on seed after steeping, mix thoroughly together with soil, after vexed 3.5 hours in soil, then are sowed.

(8) sow earthing: during sowing, seed-bearing soil will be contained and be sprinkling upon in seedbed, must be uniform when spreading fertilizer over the fields, can not With the thickness having have thin, irregular when preventing from emerging.After planting want earthing, earthing is to cover the topsoil initially digging out planting On son, earthing keeps the humidity around seed, in order to avoid wind makes the water loss in soil excessive.Four seasons Lignum Pini Nodi after planting earthing 2 centimetres it is not possible to earthing is too thick, earthing is too thick to make seed top not be unearthed, making emergence difficult.

(9) seedling stage manages with delicacy: the seedling management of four seasons Lignum Pini Nodi is that comparison is extensive, last year after planting, waters except pouring Outside, substantially there is no other management.In after planting Second Year spring, thinning is needed to fill the gaps with seedlings.Because through the growth of a year, Ilex purpurea Hassk.[I.chinensis Sims Pine seedling have grow close, growing of having is dilute, at this moment, we overstocked seedling dig out come, mend the place being short of seedling it is ensured that Seedling is evenly distributed.Water and fertilizer condition is good, the area that the soil is porous, can be in the way of using dense planting, and general seeding row spacing is at 16 centimetres Left and right is just permissible.Water and fertilizer condition is poor, the harder area of soil property, can be in the way of using thin planting, and seeding row spacing can expand 25 lis to Rice.Have the excessively weak seedling of some growing ways, can in conjunction with thinning, directly hoe go, general principle be little stay big, go weak stay strong.Pine The edaphic condition that soil is hoed up weeds in nursery is good, and weeds also can grow very vigorous, and these miscellaneous ability fight for nutrient with seedling, so, pine It is requisite that soil is hoed up weeds.When annual spring and summer are that weed growth is the most vigorous, carry out once within typically every 16 days Loosening soil, weeding, improves breathability and the water penetration of soil, and management of weeds endangers, and keeps the clean no weeds of nursery.Loosening soil, weeding Soil water evaporation can also be reduced, adjust the soil moisture, reduce irrigation frequency, be conducive to the growth promoter of root system.

(10) water and pour water: annual March to October, be the branch of four seasons Lignum Pini Nodi seedling and the needle speed of growth the fastest when Phase, and the growth that the rainwater in 3 to May tends not to meet seedling requires.So four seasons Lignum Pini Nodi is to the requirement watered, main collection In in March to June, if this period does not always rain, can pour water in time, typically every 15 days fill a water.

(11) sowing time fertilising controls: for promoting nursery stock to mushroom out, improves seedling quality, from the beginning of after planting Second Year, often Late June to the mid or late July in year, apply disposable fertilizer every first quarter moon, every mu imposes 20 kilograms of compound potassium sulfate fertilizer every time.August part Stop imposing compound potassium sulfate fertilizer later, impose nitrogen-phosphorus-potassium compound fertilizer when having ready conditions in right amount, to promote nursery stock ending fully wooden Change.

(12) insect protected diseases prevention: the common insect pest of Ilex purpurea Hassk.[I.chinensis Sims loose seedling period is few, and common disease is damping-off, and vertical disease is the four seasons A kind of leaf diseases of Lignum Pini Nodi, seedling obtained damping-off, was the most advanced and sophisticated jaundice of needle, later gradually to whole needle during beginning Spread.The cause of disease of damping-off is Pestalotia funerea, and pathogen survives the winter with conidium and mycelium in the tree sick leaf.Vertical withered Using the method preventing and treating of laxative, medicine can use carbendazim etc. to kill the medicine of funguses to disease.Consumption to specifications is watered, Sprayed with aerosol apparatus.Will carefully when spraying, from trunk to branch, high and low will be sprayed onto.Damping-off is typically in 5 Start the moon to occur, the 6-9 month is the morbidity Sheng phase, and with mercury dropped, sickness rate is gradually lowered, after November, disease stops sending out substantially Raw.So starting it is necessary to note observing from 5 parts, if it find that the symptom of damping-off will be prevented and treated in time.

(13) plant between appropriateness: through the culture of 3 to 4 years, four seasons Lignum Pini Nodi gradually grew to 1.5 meters about, this when, nursery lot Space also very crowded, if can not transplant in time it is necessary to timely thinning.If their length of leaving down, just Can airtight, therefore, again thinning to promote the growth of treelet.This time thinning, also will carry out in spring, work as temperature When degree is stablized more than 15 degrees Celsius, first water in nursery lot, water latter second day, can be transplanted with lifting.At this time seedling it Between seeding row spacing to reach 1.5 meters about.During lifting, 25 centimeters to excavate around trunk, not hinder root system or few wound as far as possible Root system.Plant in time after digging out.

5th, transplant the management of afforestation: four seasons Lignum Pini Nodi cultivates 3 to 5 years afterwards it is possible to transplant afforestation in nursery lot.At present, The four seasons Lignum Pini Nodi of China is mainly used as afforestation, Ilex purpurea Hassk.[I.chinensis Sims Guia Hill ground planting technology.

(1) turn over and cultivate site preparation: site preparation is one important procedure of afforestation, be that afforestation is front turns over the afforestation cultivated to reproducing area soil Technical measures.Site preparation makes soil become loose first, is on the one hand conducive to the stretching, extension of seedling root, on the other hand improves soil Water-holding capacity.Fish-scale pit site preparation is a kind of conventional method of hillside afforestation, is usually used in the gradient lean more than 30 degree Thin mountain region.Because the scale that the tree well shape after site preparation looks like fish is the same, cry fish-scale pit.Fish-scale pit site preparation is to earth's surface Vegetation deterioration is less, is the important method of soil preparation of Methods in Slop Improvement.The concrete grammar of fish-scale pit site preparation is: sets by afforestation on hillside Meter, digs approximately semi-moon shaped hole, and the size in hole can change according to the difference of landform and seeds of planting, and general hole is wide by 1.8 M, cheats long 1.2m, hole is away from 1.5m.First table mound is placed on the top in hole when digging pit, mellow soil is deposited in the lower section in hole, a rabbet plane Hole, carrys out the stone detection in soil layer, builds into a weir, high 18cm, these stones with picking the lower edge in hole for the stone coming Head is to gather materials on the spot, and prevents soil erosion again, and outside such fish-scale pit, high the inside is low, serves the purpose retained and conserved soil moisture.? Hole top about two jiaos each tiltedly open one ditch so that draw storage more rainwater.

(2) be rationally colonized: the whole ground that is over it is possible to seedling of planting, because seedling is all with Tu Tuo, so only needing to dig one The hole of individual very little, is so more conducive to conserve water and soil, as long as it is just permissible Tu Tuo to be put in completely.Tu Tuo is put in hole it Afterwards, then banket, steady and sure, banket with nutrition mass of soil unexposedly face, trample when do not damage mass of soil for degree.After seedling is planted above, Pour a water immediately, second day, then pour second water.The management of 1 to three year after afforestation, in 1 to three year after afforestation, be often Loosening soil, weeding, it is to avoid weeds and seedling fight for moisture.Weeding is loosened the soil and is prevented from moisture effective consumption, is to ensure that treelet survives Important technical links with growth.

(3) suitably water: four seasons Lignum Pini Nodi becomes age tree root to fasten deep, the moisture of abundance can be absorbed from soil, so one As do not need to water.If spring rainwater is few, weather is more arid, can be suitable pour water several times.

(4) prevention and control of plant diseases, pest control: except the preventing and treating of seedling stage common damping-off, become age tree also will prevent and treat Ilex purpurea Hassk.[I.chinensis Sims pine moth Harm.Ilex purpurea Hassk.[I.chinensis Sims Dendrolimus Lepidoptera Lasiocampidae, is the normal of the conifer seeds such as harm four seasons Lignum Pini Nodi, pinus elliottii, torch pine See insect.Ilex purpurea Hassk.[I.chinensis Sims pine moth is survived the winter with larva, arrives whenever spring, the pine moth surviving the winter swarms out successively, makes to pine forest Become very big loss.Therefore, the pine moth that before the arriving of the beginning of March spring, preventing and treating is survived the winter will play a multiplier effect.Intend deinsectization Chrysanthemum lipid drug is the major pharmaceutical agent preventing and treating pine moth at present.Consumption to specifications, pyrethroid lipid medicine is added water Dilution spraying, prevention effect all can reach more than 90%.Pyrethroid to person poultry harmless and can ensure pine moth natural enemy Apiss and the safety of birds.Pyrethroid lipid medical treatment pine moth is efficient and economical.Because pine moth is to chrysanthemum fat pesticide Especially sensitive, every mu of usage amount is atomic, cost accounting be organochlorine, 1/10th of organophosphorus pesticide.

(5) pruning: four seasons Lignum Pini Nodi with tall and big tall and straight, attitude pretty for characteristic, but if being allowed to free growth, but can not Obtain preferable tree-shaped, now we looking at, four seasons Lignum Pini Nodi can be turned out charming tree-shaped by which method.Remove Aerial shoot: four seasons Lignum Pini Nodi when just transplanting, not beta pruning bar as far as possible, it is allowed to grow, in the autumn to after transplant, just can will set Dry branch within 10 centimetres of ground all removes, and these branches are contacted with ground, are corroded by dust storm and moisture, base This value do not viewed and admired, so, can be cut off with shears to the greatest extent.Remove back branch: on the side shoot of four seasons Lignum Pini Nodi, often president Go out branch vertically upward, we are its " back branch ".These branch growing ways are very prosperous, long upwards by them, can cause branch Intersect, be not only unfavorable for divulging information, also destroy open and flat tree-like, so Second Year autumn after transplanting, must be these backs Branch all removes.Examine the growing way of four seasons Lignum Pini Nodi, back branch growed prosperous without pruning, its growing way even presses through Major branch, which forms the phenomenon of two major branch parallel growths, for this excessively prosperous Fructus Gardeniae, must cut it and go, Ensure the normal growth of branch.

(6) finished product tree crown shaping: after four seasons Lignum Pini Nodi is afforested 3 years, in addition to annual attention prevents pest and disease damage, avoid the need for Do other management, leaving, it freely grows, and grows up to towering tree.Ilex purpurea Hassk.[I.chinensis Sims pine trunk leads to directly, and branch and leaf are beautiful, attitude end The village, has high ornamental value, and the utilization in afforestation is also more and more extensive.Through the four seasons Lignum Pini Nodi of meticulous shaping, Obvious center is had to do, growth is vigorous；Side shoot is evenly distributed in center and does, and horizontally outward stretches out；Sprig life in side On branch, density is uniform；So in layer it is arranged in order, form tower tree crown.
