Abstract

The invention belongs to the field of compound fertilizers in agricultural production and particularly provides a compound fertilizer for preventing soil salinization. The compound fertilizer for preventing soil salinization comprises, by mass, 20-30 parts of cow dung, 10-15 parts of chicken manure, 5-10 parts of rotted leaves, 70-80 parts of black soil, 30-50 parts of rice chaff, 20-30 parts of soybean straw, 2-5 parts of phosphate fertilizer and 1-2 parts of ferric sulfate. The compound fertilizer for preventing soil salinization contains a large number of organic matter, is stable and long-term in fertilizer efficiency, enables production and income to be increased, enables nutrient utilization rate to be improved and enables the physical and chemical properties of soil to be improved.

Description

technical field [0001] The invention belongs to the field of compound fertilizers in agricultural production, in particular to a compound fertilizer for preventing soil salinization. Background technique [0002] my country is a big agricultural country, and it is also a big country in the production and use of chemical fertilizers. The domestic use of chemical fertilizers has increased from less than 0.1% in 1949 to the vast majority of crops currently being planted with chemical fertilizers. At present, my country's total output and application of chemical fertilizers rank first in the world. . The status of fertilizers in rice production is very important, especially chemical fertilizers, which play a pivotal role in increasing agricultural production. The input of chemical fertilizers is increasing year by year. However, at present, the approximate range of the utilization rate of chemical fertilizers in the current season in my country's rice fields is: nitrogen fertiliz...
