Abstract

The invention discloses a preparation method of a composite fertilizer capable of improving saline-alkali soil. The preparation method is capable of solving a problem in the prior art that long term continuous modification of saline-alkali soil by inorganic fertilizers is impossible to realize. The preparation method comprises following steps: raw materials are weighed at a certain weight ratio; black alum, desulfurization gypsum, a nitrogen phosphorus and potassium composite fertilizer, and boric acid are smashed and sieved, and are uniformly mixed with an organic fertilizer, and an obtained mixture is subjected to packaging and sterilizing so as to obtain an A bag; ingredients of a B bag are uniformly mixed so as to obtain a B bag. The A bag comprises, by weight, 10 to 15 parts of black alum, 5 to 12 parts of desulfurization gypsum, 40 to 60 parts of the organic fertilizer, 12 to 30 parts of boric acid, and 14 to 40 parts of the nitrogen phosphorus and potassium composite fertilizer, and the B bag comprises, by weight, 10 to 15 parts of trichoderma microbial inoculum, 20 to 50 parts of bacillus subtilis microbial inoculum, and 20 to 30 parts of bacillus licheniformis microbial inoculum. The preparation method is simple; operation is convenient; and the composite fertilizer prepared via the preparation method is capable of improving saline-alkali soil continuously for a long term.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a preparation method of compound fertilizer for improving saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high. [0003] In the process of utilization, saline-alkali land can be divided into light-saline-alkali land, moderate-saline-alkali land and heavy-saline-alkali land. Light saline-alkali land means that its emergence rate is 70%-80%, and its salt content is less than ...
