As far as the poplar planting method is concerned, the large seedlings that are 2-3 years old are usually planted into trees, and another conventional method of poplar vegetative propagation "hard branch cutting"; the above two methods all have large footprints and low propagation rates. , the transportation volume is large, and the cost of large-scale afforestation is high, which affects the progress of greening

Embodiment
[0015] Build the seedbed: build the seedbed 8 in the flat and high-dry leeward plot, build a seedbed wall 10 with a height of 40 cm and a width of 12 cm around the seedbed 8, and lay 20 cm thick wool sand or wind sand on the bottom of the seedbed 8, and level it; 20cm thick wind sand and fully decomposed farmyard manure are mixed in a ratio of 1:1. At the same time, 20g of potassium mixed with phosphorus granules and 5g of ground bacteria powder mixture are applied per square meter, and then leveled; the upper layer is 10cm thick. The pure building sand is leveled, and the area of the seedbed 8 depends on the size of the seedlings, generally 300-600m 2 It is appropriate.
[0016] Set water delivery sprinkler irrigation device: build pool 1 near the seedbed 8, the size of the pool 1 is generally 1.2m deep, 2m wide, 3m long, the pool 1 has a built-in submersible pump 2, and the main pipe 4 is connected to one end of the submersible pump 2 and the sprinkler irrigation control d...

The present invention relates to a cultivation method for making asexual propagation of poplar, specially, it is an open shoot-cutting seedling-cultivating method for poplar. Said method includes the following steps: selecting flat, high-arid and leeward country block to create seedling bed, building inclosure wall around the seedling bed by using bricks, laying a layer of sand layer whose thickness is 20 cm as base layer of said seedling bed, laying a layer of mixed manure soil formed from sand and farm manure according to mixing ratio of 1:1 as intermediate layer whose thickness is 20 cm, then laying a layer of pure building sand as upper layer whose thickness is 10 cm, then laying a brick pathway every 1.2 m on the seedling bed, seeting wind-proofing screen around the seedling bed, mounting shading net on it, selecting and cutting shoot seedling, cutting and making management.
Description
technical field [0001] The invention relates to a cultivation method for asexual propagation of poplars, in particular to a method for growing seedlings of poplars in open-air twig cuttings. technical background [0002] At present, in order to improve the ecological environment, our country vigorously advocates returning farmland to forests, and large-scale afforestation requires a large number of seedlings. As far as the poplar planting method is concerned, the large seedlings that are 2-3 years old are usually planted into trees, and another conventional method of poplar vegetative propagation is "hard branch cutting"; the above two methods all have large footprints and low propagation rates , the transportation volume is large, and the cost of large-scale afforestation is high, which affects the progress of greening. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned technical problem, provide a kind of propagation s...
