Abstract

The invention discloses a biological type organic-inorganic compound fertilizer for improvement in saline land and a preparation method thereof. The preparation method includes the steps that attapulgite, potassium humate and zeolite are ground into mixture powder, the mixture powder is mixed with polyglutamic acid and wood vinegar, water is added for constant-temperature stirring, dissolving liquor is obtained and then evenly mixed with a mixture of urea, monoammonium phosphate, potassium sulfate, ammonium sulfate and trace element fertilizer which are mixed evenly and heated to be molten, the mixture is subjected to granulating, drying and cooling, a microbial agent is sprayed on the surface of the cooled granulated mixture, then the mixture is evenly mixed with citric acid, calcium superphosphate, polyacrylamide and livestock and poultry fermented organic fertilizer, and the biological type organic-inorganic compound fertilizer is obtained. The prepared biological type organic-inorganic compound fertilizer can effectively reduce salt and alkaline in saline alkali soil and integrates the advantages of organic fertilizer, inorganic fertilizer and slow release fertilizer, the utilization rate of the fertilizer can be increased, and the improvement effect on soil of microbial floras is effectively utilized; the fertilizer has the advantages of being long in duration of fertilizer efficiency, good in fertilizer efficiency, environmentally friendly and free of pollution.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a biological organic-inorganic compound fertilizer for saline-alkali land improvement and a preparation method thereof. Background technique [0002] There are large areas of saline-alkali land distributed in our country, and the degree of salinization is expanding, especially in coastal areas. Land salinization not only reduces agricultural production in our country, but also causes great losses. Due to the increasingly serious degree of salinization, large areas of land gradually become wasteland, with no grass growing and no harvest. Transforming saline-alkali land and improving the agricultural production of saline-alkali cultivated land is one of the important tasks of agricultural development in my country. Among the many improvement methods of saline-alkali land, the application of saline-alkali land improvement fertilizer has been favor...
