Abstract

The present invention discloses a repairing agent of a saline alkali land for planting cotton. The components in the formula of the repairing agent comprise, by weight, 28-44 parts of desulfuration gypsum, 20-35 parts of a microbial agent, 5-11 parts of polyacrylate potassium, 25-45 parts of silica, 16-32 parts of sodium-based bentonite, 3-7 parts of sulfur, 8-19 parts of soluble humic acid, 4-12 parts of ferrous ammonium sulfate, and 8-17 parts of amino acid powder. According to the present invention, with the added soluble humic acid, the added ferrous ammonium sulfate and the added amino acid powder, the soil can be further improved, the growth environment of the cotton can be improved, the salt rejection rate of the soil can be increased, and the growth of the cotton can be promoted; and the rich raw materials are used to replace the single raw material in the traditional repairing agent, such that the repairing time of the saline alkali land can be substantially shortened, and the repairing agent and the repairing method can be widely promoted and used.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil restoration, and more specifically relates to a saline-alkali soil restoration agent suitable for planting cotton. At the same time, the invention also relates to a restoration method for saline-alkali land suitable for planting cotton. Background technique [0002] With the rapid increase of population and the deteriorating climate conditions, the salinization of land is a worldwide ecological problem. An important limiting factor for the sustainable development of world agriculture. my country's salinized cultivated land area is about 34.67 million hm2 (520 million mu), ranking fourth in the world, second only to Australia, Mexico, and Argentina. my country's saline-alkali land is mainly distributed in 17 provinces including northeast, north, northwest and coastal areas. In order to ensure the safety of food production in our country, improve the ecological environment, and realize...
