Method for relieving forest belt soil coercing by cutting roots and sticking film

Abstract

The invention provides a method for relieving forest belt soil coercing by cutting roots and sticking a film. The method comprises the following steps: ditching along one side of a forest belt; cutting a trench wall close to one side of a farmland to be smooth and vertical to a trench bottom; sticking the plastic film on one side close to the farmland and the vertical smooth trench wall; refilling soil and filling up, and exposing the film out of the ground; and after the refilled soil is sunken, filling up until the film is not exposed. By the aid of the method, a land can be effectively released, and the grain yield in a forest belt soil coercing range is increased; the upper biomass and the seed quality of a crop field are improved; the method has the characteristics of simplicity and feasibility, less investment, rapid effect, high benefits, long acting time, one-time investment, zero-cost benefits for many years and the like.

Description

technical field [0001] The invention relates to the field of alleviating forest threat, in particular to a method for reducing forest threat by cutting roots and applying film. Background technique [0002] Forest belts are also called shelterbelts. Refers to the general term for the protective tree rows built in the form of belts on farmland, grasslands, residential areas, factories and mines, around reservoirs, railways, roads, rivers, both sides of canals, and coastal areas. The forest belt flank is a common phenomenon, and its main manifestation is that the trees in the forest belt will cause poor growth and development of crops near the two sides of the forest edge, resulting in reduced yield. The range of forest belt flanks is generally within the range of 1-2H (H refers to tree height) on both sides of the forest belt, and the most influential one is within the range of 1H. The result of our years of research is that the main threat range of the poplar forest belt i...

[0003] Farmland shelterbelts have obvious effects of protecting fields and increasing production, but the problem of land threat has been perplexing the vast number of rural cadres and the masses, so that it has become the main ideological obstacle for building farmland shelterbelts

Such as: artificial ditching or mechanical ditching and root removal methods, etc. Although these methods have played a certain role in reducing the threat of forest belts, the root system will regenerate quickly after root removal. high, poor
