Summary of the invention

goal of the invention: the object of the invention is for problems of the prior art, a kind of Guangxi green plum seedling-cultivating method is provided.

technical scheme: Guangxi of the present invention green plum cultivation method, specifically comprises the following steps:

1. collect seed: before annual seed maturity comes off, the shrub weeds under the green plum of Guangxi are removed totally, spread Polypropylence Sheet, after wait kind comes off, collect;

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 12 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 30～35 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, 1.0～1.2 meters of furrow face widths, high 15～20 centimetres, 30～35 centimetres of furrow furrow widths;

5, use sufficient base fertilizer: rise after good furrow, mu applies fertilizer to the subsoil 2500～3000 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: Guangxi green plum Seedling Stage be afraid of day burn, 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 cultivate by large area development Guangxi green plum, 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 30 centimetres, the afforestation of going up a hill of can emerging.
