Summary of the invention

The object of the present invention is to provide the cuttage and seedling culture method of a kind of willow.

The present invention adopts following technical scheme:

The cuttage and seedling culture method of willow, comprises following content:

(1) selection of land, whole ground: select the sandy loam that soil is loose, physical features is smooth, have a good transport service, plough deeply soil 30-35cm, then mu applies urea 90-100kg, rabbit excrement 30-40kg, ammonium chloride 6-8kg, ammonium carbonate 2-4kg, nanometer rock phosphate powder 20-30kg, amargosa 10-12kg, Herba Lophatheri extract 3-5kg, silkworm excrement 30-40kg, nanometer jade powder 10-12kg, oil foot 3-4kg, gelatin 3-4kg, epoxy Linseed oil 4-5kg, sodium selenite 5-6kg, boric acid 3-4kg and soybean oil 3-5kg; Then harrow fine earth earth, in evenly rake buries by fertilizer agricultural chemicals, make the loose soil layer of 20-25cm simultaneously;

(2) plant the system of cutting of bar collection and cuttings: intercepting middle part degree of lignification is high, the full stalwartness of bud, dry as cuttings without the seedling of damage by disease and insect; With sharp cutter, cut cuttings processed, cutting length 12～15cm, rugosity 1.0～1.5cm is advisable, and first lateral bud of cuttings upper end should be intact, should have the spacing of 1cm between upper cut and the first lateral bud;

(3) cuttage: early and middle ten days completed cuttage and was advisable mid or late Febuary to March; Cutting density is advisable with 3500-3800 plant/acre; By the above-mentioned sandy loam of the vertical insertion of cuttings, compacting soil, contacts closely soil with cuttings a little;

(4) after cuttage, manage: comprise cutting back, pinching, bud picking, remove sublateral shoot, pruning, pruning auxiliary support branch;

(5) topdress: April week about foliage-spray foliage fertilizer once, described foliage fertilizer forms urea 23-25, egg shell powder 10-12, copper sulphate 2-4, phosphorus pentoxide 1-2, ammonium molybdate 0.3-0.5, glutamic acid 0.8-1.2, lactic acid bacteria 3-4, flame nettle powder 2-4, radix boehmeriae 4-6, the green flowers and plants 1-3 of greenery, left-hand rotation rattan 2-4, water bank plate 4-6, phoenix tree flower 1-2, willow bark 3-4 and bitter Lang Shu 1-2 by following weight portion; Preparation method is: flame nettle powder, radix boehmeriae, the green flowers and plants of greenery, left-hand rotation rattan, water bank plate, phoenix tree flower, willow bark and bitter Lang Shu are decocted and obtain liquid extract and the dregs of a decoction, and the dregs of a decoction are soluble in water, and high-speed stirred is disperseed, and then low temperature drying obtains powder; Finally liquid extract, powder and other surplus stocks are merged and mixed, drying-granulating obtains; The seedling growth later stage, every the potassium dihydrogen phosphate solution of 5-7 days foliage-sprays 0.3% or the potassium sulphate liquid of 0.2-0.3% 1 time.

Beneficial effect of the present invention:

Seedling-cultivating method of the present invention can improve willow quality, effectively improves Cultivated-land Fertility, improves fertilizer provision from soil environment, can chesson, strengthens soil aggregate, improves preserve moisture and fertility ability, increases the soil organic matter, meets the needs of willow to various elements.
