Abstract

The invention discloses a saline-alkali soil conditioner, as well as a processing method and application thereof, and belongs to the technical field of saline-alkali soil improvement. The conditioner is prepared from the following raw materials in parts by weight: 240-320 parts of ardealite, 140-200 parts of oil cake, 70-100 parts of rectorite, 12-20 parts of polyaluminum sulfate, 40-80 parts of mushroom residues, 10-20 parts of polymeric ferric sulfate, 20-30 parts of apatite, 15-24 parts of acid, 20-30 parts of polymeric ferric silicate sulfate, 10-20 parts of wild sweet potato stems and 10-20 parts of cactus. According to the saline-alkali soil conditioner, the main raw materials, such as ardealite, oil cake, mushroom residues, rectorite and the like, are low in price and wide in source, the problems of cost and environmental pollution caused by stacking of the ardealite and the oil cake can be effectively solved by utilizing the ardealite and the oil cake, and the saline-alkali soil conditioner prepared from the main raw materials has a good effect of improving the saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a saline-alkali land conditioner and its processing method and application. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in ...
