Summary of the invention

goal of the invention: the object of the invention is for problems of the prior art, provide one to hold up a day tree seedling-cultivating method.

technical scheme: day tree cultivation method of holding up of the present invention, specifically comprises the following steps:

1. seed collecting: before seed maturity comes off every year, the shrub weeds of holding up under day tree are removed totally, spread Polypropylence Sheet, collect after wait kind comes off;

2. seed treatment: bury with moistening fine sand or liver moss after collecting seed, to ensure the germination rate of seed, before sowing, fruit wing is removed;

3. nursery lot is selected: select the gradient to be less than 15 degree, soil layer is deep, and the soil is porous, leeward, and short, traffic at sunshine, irrigation, draining facilitate place to be advisable.

4. wholely: nursery lot is wanted careful whole ground, and first cut down ground weeds shrub to dry and burnout for 7～August, deep-cuts and dig, the degree of depth reaches 35～40 centimetres, remove a tree grass roots, through weathering after a while, then dig once before sowing, break up the clods, make soil fully in small, broken bits, then laterally play furrow along contour, 80～100 centimetres of furrow face widths, high 15～20 centimetres, 20～30 centimetres of furrow furrow widths;

5, use sufficient base fertilizer: rise after good furrow, mu applies fertilizer to the subsoil 3000～3500 kilograms, the decomposed manure material that base fertilizer is 85%～90%, 10%～15% phosphorus potash fertilizer and trace element fertilizer fully mix, evenly remove on furrow face, after plough under in soil;

6, sowing: when sowing, seed be inverted to (top is downward, and base portion upwards) or lain on one's side on seedbed, then lid layer thin soil was just to hide seed or to cover to 2/3rds of seed, and spacing in the rows is 5～8 ㎝, and line-spacing is 6～10 ㎝;

7, shelter from heat or light: hold up day tree and be afraid of day to burn at Seedling Stage, need certain sheltering from heat or light, just can guarantee nursery stock normal growth, therefore, after seedling all sprouts, should take in time cool canopy and shade, the light transmittance of sunshade net is advisable with 50%～60%, late December the dismountable thing that shades;

8, weeding: carry out uprooting weed after should selecting rain or after irrigating, sapling is loosening or be taken up when preventing uprooting weed, and applying finger is pinned surrounding soil, and the hole that grass roots is stayed is recessed fills and leads up with fine earth, have loosening nursery stock should be in time by soil by being tight compact;

9, fertilising: the growth of seedling initial stage, execute the mixing fertilizer of the low nitrogen of high phosphorus once, nitrogen phosphoris and potassium fertilizer ratio is advisable with 1:3:1, executes phosphorus potash fertilizer 1 time, to promote nursery stock lignification after mid-December;

beneficial effect: compared with prior art, its beneficial effect is in the present invention:

The present invention adopts growing nursery and culture, can large area development hold up a day tree cultivation, forms industrialization, and percentage of seedgermination reaches more than 95%, and planting percent reaches more than 92%, 6～8 months seedling stages, and on average up to more than 35 centimetres, the afforestation of going up a hill of can emerging.
