Method for preventing aeolation of soil

Abstract

The invention discloses a method of preventing soil from drifting and a device, which comprises: (1) pressing raw materials of maize straws and wheat straws and the like through the straw forming machine, preparing into straw poles with a diameter 50-100 mm and length 800-1000 mm, coating waterproof glue on an outer surface; (2) arranging the straw poles in the farmland, constituting windbreak fences, wherein a distance between two windbreak fences is 4-5 m. When wind blows over the farmland, the windbreak fences block away the wind, causing the wind speed to reduce, thereby reducing corrosiveness of the wind on the soil and reducing soil loss.

Description

technical field

[0001] The invention relates to the technology of preventing wind erosion and desertification of farmland soil in the northern dry farming area, in particular to a method for preventing wind erosion of soil. Background technique

[0002] In the northern dry farming area, especially the farmland in the agro-pastoral transitional zone, the soil wind erosion and desertification are serious due to wind blowing. Usually, crop residues such as corn stubble and wheat stubble after harvest are used as biological hedges to build windbreak fences on bare farmland. Prevent the soil from being blown away by the wind and reduce the erosion effect of the wind on the soil. The main disadvantage is that corn stubble and wheat stubble cannot be planted densely, are easy to rot, have poor strength, and have a small windproof area, so the effect of preventing wind from eroding the soil is poor. Soil loss is more. Contents of the invention
