Problems solved by technology

However, the production process of the inorganic liquid fertilizer and organic liquid fertilizer in this patent is relatively complicated, the cost is high, and it is troublesome to use
CN101417286 protects a saline-alkali soil remediation agent, including desulfurized gypsum, natural organic matter, microbial fertilizer and inorganic nutrients. It is disclosed in the patent that when desulfurized gypsum is used as a soil improver, it is mainly used to reduce the alkalinity of alkaline soil. However, it has little effect on reducing the salinity content of the soil, and cannot provide the crops with the required nutrients such as nitrogen, phosphorus, potassium, and organic matter, nor can it increase the biological activity.

Abstract

The invention provides a saline-alkali soil fertilizer, which comprises humic acid, gypsum, microorganisms, manure and nitrogen fertilizer. Potassium fertilizer, phosphate fertilizer and silicon fertilizer are used to solve the technical problem of low crop yield in saline-alkali land. The invention has the advantages of low cost, scientific and reasonable proportioning, sufficient nutrients, high utilization rate and obvious yield increasing effect, is especially suitable for the growth of crops in saline-alkali land, can effectively improve saline-alkali land, and provides guarantee for farmers to increase production and generate income.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of agricultural fertilizers, in particular to a saline-alkali soil fertilizer and a preparation and application method thereof. [0003] 【Background technique】 [0004] my country is a country where saline-alkali soil is widely distributed. There are more than 500 million mu of saline-alkali land in our country, and saline-alkali soil is not conducive to plant growth. At present, there are 17 provinces, municipalities, and autonomous regions in my country where saline-alkali land is distributed, mainly in the northwest, north, northeast and coastal areas. It is imminent to transform the saline-alkali land and increase the agricultural output of the saline-alkali land. [0005] The main feature of saline-alkali land is that it contains more water-soluble salt or alkaline substances. Due to the high salinity and high alkalinity, the soil humus is leached and the soil structure is damaged. It is sticky...
