Abstract

The invention discloses an iron-based saline-alkali soil conditioner and an application method thereof.The application method comprises the steps of preparation of a soil conditioner A, preparation of a soil conditioner B and matched application of the soil conditioner A and the soil conditioner B. The soil conditioner A comprises 85-95 parts of industrial iron powder, 5-15 parts of sulfur powder and 0-5 parts of microelements; according to the application method of the iron-based saline-alkali soil conditioner, the iron powder is modified by the sulfur powder, and the application time of the conditioner A and the conditioner B is combined, so that the iron-based saline-alkali soil conditioner is obtained, and the iron-based saline-alkali soil conditioner has a relatively good improvement effect on saline-alkali soil and has an obvious promotion effect on crop growth.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to an iron-based saline-alkali soil improver and an improvement method thereof. Background technique [0002] Salinized soil is widely distributed all over the world, and the problem of soil salinization is a worldwide problem. Rational development and utilization of huge saline-alkali land resources is an important breakthrough to solve the contradiction between the increasing population and the rapid reduction of cultivated land area, and it is also a hot spot that scientists have been studying. [0003] Soil improvement in saline-alkali land is a difficult, highly complex, and long-term task, so it has received long-term attention from relevant scholars at home and abroad. There are many ways to improve saline-alkali land. Currently, such as irrigation and drainage engineering measures, increasing organic fertilizer, and agricultural measures such as plant...
