Abstract

The invention discloses a fertilizer for corns in the saline-alkali soil and an application thereof, belonging to the technique of soil improvement and efficient fertilization, solving the problems of easiness in soil hardening, bad soil structure, bad tilth, and low bioavailability of nutrients required by corn growth caused by high pH and high salinity. The fertilizer for corns in the saline-alkali soil comprises 7.3 weight parts of sulfurous fertilizer, 10 weight parts of humic acid, 24 weight parts of N, 12 weight parts of P2O5, and 6 weight parts of K2O. When the fertilizer is applied, the application amount is 50kg / mu. The fertilizer disclosed herein is suitable for corn production in the saline-alkali soil, can improve the physical and chemical property of the soil and reduce the accumulation of salts on the soil surface, and can raise the corn yield by 20-30%.

Description

technical field [0001] The invention belongs to the technology of soil improvement and high-efficiency fertilization, and relates to a special fertilizer for corn in saline-alkali land and its application. Background technique [0002] The quality of saline-alkali soil is poor, and the availability of nutrient elements required for plant growth and development is low, resulting in poor development of plant roots, unhealthy plant bodies, and seriously affecting crop yields. At present, various soil improvement methods have been proposed, but a very effective saline-alkali soil improvement method has not been used in practice, and there is no product that integrates improvers and crop-specific fertilizers into one. [0003] Patent 99112075.2 discloses an agricultural soil improver, which is composed of borax, magnesium sulfate, zinc sulfate, copper sulfate, gypsum, molybdenum ammonium acid, manganese sulfate, sulfur, and ferrous sulfate in a certain proportion by weight. Impr...
