Problems solved by technology

[0004] The ferrous sulfate added in the above patents is basically ferrous sulfate for industrial use, and it is simply mixed with other materials. There are two problems when it is applied in farmland: one is that ferrous sulfate is easy to absorb moisture and agglomerate, increasing Difficulty in application; the second is that ferrous sulfate is easy to change form when exposed to the air, from ferrous iron to ferric iron which is difficult for crops to use, the effect of soil acid regulation is weakened, and the utilization rate of iron by crops is reduced

Abstract

The invention discloses a ferrous film improver based on inland saline-alkali soil. The ferrous coating improver is composed of a core and a sulfur film coated on the core surface. The core is prepared by adding an adhesive to the following raw materials in parts by weight and carrying out granulation: 5-10 parts of sulfur, 30-60 parts of ferrous sulfate, 5-10 parts of iron powder, 5-15 parts of halophyte leaf dry powder, 1-5 parts of dry walnut green peel powder, 5-10 parts of oxalic acid, 10-20 parts of potassium humate and 1-5 parts of bentonite. The ferrous film improver effectively prevents ferrous iron in the ferrous sulfate from being oxidized into ferric iron and solves the problem of high tendency to moisture absorption and caking in the ferrous sulfate. The prepared film improver has the functions of soil improvement and crop nutrition, is suitable for improving inland saline-alkali soil in China, and has higher practical value.

Description

technical field [0001] The invention belongs to the technical field of saline soil improvement, and relates to a coating improving agent capable of improving inland saline-alkali soil and crop nutrition, and a preparation method of the improving agent. Background technique [0002] my country has about 550 million mu of saline-alkali land resources that can be used, of which more than 100 million mu of saline-alkali land resources have good governance conditions and agricultural utilization value. The area of ​​inland saline-alkali land is the largest, including the northwest, northeast and the middle and upper reaches of the Yellow River, accounting for about 69% of the country. Improving inland saline-alkali land is of great significance to ensuring food security. [0003] The use of chemical modifiers is the main way to improve inland saline-alkali land at home and abroad. Desulfurization gypsum, phosphogypsum, sulfur, ferrous sulfate, aluminum sulfate, etc. are commonly ...
