Abstract

The invention discloses a soil improvement agent for a saline-alkali land. The soil improvement agent is prepared from the following raw materials in parts by weight: 100-200 parts of humic acid, 50-100 parts of algae mud, 50-100 parts of biochar, 1-5 parts of a biological fungicide, 1-5 parts of a biological enzyme agent, 50-100 parts of pine needle meal, 50-100 parts of brewer's grain, 20-50 parts of sulfur slag, 20-50 parts of bentonite, 100-200 parts of chicken manure, 30-50 parts of straw, 20-30 parts of feather meal and 20-30 parts of earthworm powder. The sulfur ions and sulfuric acid contained in the added sulfur slag are firstly separated out by hot water, are attached to the biological fungicide by virtue of the biological fungicide and then are bound with ions in the saline-alkali land. By further adding an acidic amino acid chelating solution and a bamboo vinegar solution, the pH value of the saline-alkali land is decreased; and by adding the biochar, coconut chaff and rice bran, moisture and water preservation effects are achieved, and soil erosion is prevented.

Description

technical field [0001] The present invention relates to the field of soil improvement. More specifically, the present invention relates to a soil conditioner for saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. At present, due to the pollution of the environment, the abuse of inorganic fertilizers and pesticides, and the excessive irrigation, the salinization of the land is becoming more and more serious. The curre...
