Problems solved by technology

[0004] Only using fertilizers composed of inorganic elements can have a certain effect on the transformation of saline-alkali land, but if other elements and other methods are not used, the duration of the effect may be limited. Therefore, it is necessary to apply fertilizers with inorganic elements When using organic fertilizers and corresponding plant cultivation, a better improvement effect can be received

Abstract

The invention discloses improved fertilizer suitable for saline-alkali soil and a production method thereof. The improved fertilizer comprises fertilizer A and fertilizer B, wherein the fertilizer A is prepared from flue gas desulfurization gypsum, pulverized fuel ash, bentonite, zeolite, urea, ammonium phosphate and calcium chloride in a weight ratio of (30-40):(8-12):(20-30):(8-12):(6-10):(6-10):(3-5); the fertilizer B is prepared from seaweed meal, cow dung, bean pulp, straws and microbial compound powder in a weight ratio of (45-55):(20-30):(10-20):(6-10):(1-3); and the microbial compoundpowder is prepared from azotobacter chroococcum, trichoderma koningii, clostridium butyricum, bacillus subtilis and German-styple lactobacillus. The improved fertilizer can be used for effectively improving the soil structure of saline-alkali soil, increasing soil fertility and reducing alkalinity, and can be used for durably and effectively improving the saline-alkali soil by matching with plantcultivation.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an improved fertilizer suitable for saline-alkali land and a production method thereof. Background technique [0002] Most of the saline-alkali soil is related to the accumulation of carbonate in the soil, the degree of alkalinity is generally high, and plants in severe saline-alkali soil areas can hardly survive. In the process of utilization, saline-alkali land can be simply divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. Light saline-alkali land means that its seedling emergence is 70% to 80%, and its salt content is below 3 per thousand; heavily saline-alkali land refers to its salt content exceeding 6 per thousand, the emergence rate is less than 50%, and the pH value of the soil moisture exceeds 8.5, causing soil compaction, which has an inhibitory effect on the root system of crops, making crops...
