Embodiment 1

[0086] Experimental scheme of the present invention is as follows:

[0087] The experimental site was selected as the teaching and experimental nursery of Forestry College of Northwest Agriculture and Forestry University. The test material is the annual Swedish energy willow clone C (referred to as Ruineng C). Before the cultivation, the participating seedlings were dipped in mud for root treatment, and 5 kinds of treatment measures were taken in the prior art, such as level land preparation, comprehensive land preparation, fish scale pit land preparation, protective land preparation mulching of the present invention, and protective land preparation weed mulch. Invention film mulching and grass mulching test take 3 kinds of prior art soil preparation methods without mulching as contrast, set up 3 repetitions at the same time, each treatment is 1 plot, 30 plants are planted in each plot, the spacing between plants and rows is 60cm×100cm, random Arranged in blocks; the film use...

Abstract

The invention relates to a method for cultivating Swedish energy willows through protective soil preparation mode, which includes the steps of preparing soil, digging pits, planting, backfilling soil, collecting the hydrosphere, and covering and preserving soil moisture. The method can reaches the purposes of intercepting precipitation, alleviating surface runoff, reducing soil erosion, restraining the growth of herbaceous plants in the forest land and improving the productivity of the forest land. The method has obviously better effect over the prior art in aspects of habitat and species diversity of the forest land, energy willow afforestation survival rate and individual growth, soil condition of the forest land, photosynthetic parameters, growth of the new tresses of the Swedish energy willows and the like, the afforestation survival rate can be above 90% and the growth rate of the forest trees can be above 30%.

Description

【Technical field】 [0001] The invention belongs to the technical field of land preparation and afforestation. More specifically, the present invention relates to a method of growing Swedish energy willow in a protective soil preparation method. 【Background technique】 [0002] The low survival rate of trees in the arid and less rainy areas of northern my country is not only due to insufficient natural precipitation, but more importantly, loose soil, severe soil erosion, strong evaporation, limited deep soil water storage, and low water use efficiency of trees. Water shortage has become an important factor affecting the sustainable development of forestry and the construction of ecological environment in arid areas. [0003] Arrangement of afforestation land is a major process to improve environmental conditions before afforestation, and is an important part of technical measures for plantation cultivation. Under the current technical and economic conditions, it is also the on...
