Afforestation method based on fast growing and high yield of zelkova schneideriana

Abstract

The invention discloses an afforestation method based on fast growing and high yield of zelkova schneideriana. The afforestation method based on fast growing and high yield of the zelkova schneideriana comprises the following steps that (1) a planted land is selected; (2) the time for planting is selected; (3) zelkova schneideriana seedlings are selected; (4) the density of plantation is selected, wherein for one-year seedlings, the initial density ranges from 166 seedlings per mu to 111 seedlings per mu with the line spacing between the seedlings ranging from 2 m*2 m to 2 m*3 m, and the reserve density ranges from 83 seedlings per mu to 55 seedlings per mu with the line spacing between the seedlings ranges from 2 m*4 m to 4 m*s m; for two-year seedlings, the initial density is 111 seedlings per mu with the line spacing between the seedlings being 2 m *3 m, and the reserve density is 55 seedlings per mu with the line spacing between the seedlings being 4 m *3 m; (5) afforestation is conducted according to a method, wherein a plantation is conducted according to the hole planting method, the planting depths for the one-year seedlings are 2 cm-5 cm lager than those of ground diameter original soil marks of the seedlings, the specification of each plantation hole is 0.5*0.5*0.6; when the two-year seedlings are planted, the plantation holes are filed with surface soil and then are filled with growing soil, and soil covering is conducted layer by layer, all layers of soil are compacted, fixation is achieved through supporting rods, and specification of each plantation hole is 0.8*0.8*0.8; (6) cultivation and management are conducted, wherein the cultivation and management process comprises the steps of (a) branch trimming and trunk cultivation, (b) thickening through longitudinal damage, (c) intertillage and weeding, (d) water and fertilizer management, (e) insect control and (f) interplanting and breeding below seedlings.

Description

technical field [0001] The invention belongs to a fast-growing and high-yield afforestation method for beech trees. Background technique [0002] Beech trees are widely distributed in China. They grow slowly and have excellent materials. They are precious hard-leaved broad-leaved tree species and excellent tree species for viewing autumn leaves. Make street trees. Beech has strong adaptability, strong wind resistance, and resistance to smoke and dust. It is a good tree species for urban and rural greening and building windbreak forests. [0003] At present, the conventional afforestation of beech is slow in growth and low in output, resulting in low benefits. However, beech is an important tree species in greening projects, so it is necessary to improve the method of beech afforestation to achieve fast growth and high benefits. [0004] And it will bring greater economic benefits to the industry of planting zelkova, which requires higher zelkova cultivation technology. C...
