Abstract

The invention provides a saline-alkali soil fertilizer which comprises humic acid, gypsum, microorganisms, domestic manure, a nitrogenous fertilizer, a potash fertilizer, a phosphatic fertilizer and a silicon fertilizer, aiming at solving the technical problem that a saline-alkali soil land is low in crop yield. The saline-alkali soil fertilizer has the advantages that the cost is low, the preparation is scientific and reasonable, the nutrition is sufficient and high in utilization rate, and the yield-increasing effect is remarkable; the saline-alkali soil fertilizer is particularly applicable to growth of saline-alkali soil crops, the saline-alkali soil land can be effectively improved, and guarantee is provided for farmers to increase the production and generate the income.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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. [0003] 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 when wet and h...
