Soil improvement method

Abstract

The invention specifically relates to a soil improvement method, comprising the following steps: plowing the soil once, plowing the soil, and ventilating the soil naturally for 4 to 7 days; applying animal manure, spreading the animal manure evenly on the plowed soil, and exposing the soil to sunlight. Irradiate for 2 to 3 days; plow the soil for the second time, plow the soil again, and water after plowing; add plant straw, break the length of the plant straw to less than 1cm, spread it evenly on the soil surface, and water to make the plant The straw is soaked, and then covered with plastic film for 30 to 40 days; the soil is plowed three times, the plastic film is removed, the soil is plowed, and after the soil is leveled, field furrows are built and drainage ditches are excavated. The method can improve the salinization of the soil without polluting the land, has convenient operation and low cost, and has good popularization effect.

Description

technical field [0001] The invention specifically relates to a soil improvement method. Background technique [0002] Ecological agriculture is a new stage of agricultural development. At present, ecological agriculture has shown a trend of large-scale, large-scale and specialization. After the soil has been cultivated for a long time, and people often fertilize blindly during production, the physical and chemical properties and biological characteristics of the soil have changed greatly. , and the sugar-to-nitrogen ratio of plants is reduced, which is conducive to the occurrence of diseases, reduces the utilization rate of chemical fertilizers, reduces the output ratio, causes soil and surface water pollution, deteriorates the ecological environment, and reduces benefits. Therefore, how to improve soil salinization is a problem that needs to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a simple, convenient a...
