Rice fertilizer capable of improving resistance, quality and yield of rice

Abstract

The invention relates to rice fertilizer capable of improving the resistance, quality and yield of rice. The rice fertilizer consists of the following raw materials in percentage by weight: 20.0 to 27.0 percent of urea, 7.0 to 20.0 percent of ammonium sulfate, 5.0 to 13.0 percent of monoammonium phosphate, 9.8 to 17.5 percent of potassium chloride, 10.0 to 18.5 percent of calcium superphosphate, 3.0 to 6.0 percent of calcium-magnesium phosphate, 2.0 to 8.0 percent of soluble silicon, 0.1 to 0.9 percent of amino acid, 5.0 to 30.0 percent of humic acid, 0.5 to 6.0 percent of other trace elements (zinc, manganese, boron, ferrum, copper, molybdenum, selenium and the like), 0.2 to 0.5 percent of activating agent and less than or equal to 2.5 percent of water. The rice fertilizer has the advantages of comprehensively providing the nutrient required by growth of rice, improving the yield and the quality of rice, activating the nutrient of soil, enhancing the capacity of absorbing nutrient by crops, improving a soil structure, enhancing soil fertility, promoting development, and improving the resistance of the crops (disease resistance, pest resistance, drought resistance, flooding resistance, cold resistance, saline-alkaline resistance, lodging resistance and the like).

Description

technical field [0001] The invention relates to a rice fertilizer, in particular to a rice fertilizer for improving rice resistance, quality and yield. Background technique [0002] The most important food crop for our people is rice, which has a vast planting area and requires a large amount of fertilizer. However, for a long time, our people have been using traditional methods for planting, fertilizing and managing, which are not efficient and effective. In the first year of the 21st century, the Ministry of Agriculture of my country proposed the "Non-Pollution Food Action Plan", and 75 industry standards for pollution-free agricultural products were implemented. Since then, a new era of pollution-free agricultural product production has been created. [0003] At present, the environmental problems caused by environmental pollution and the destruction of ecological balance are becoming more and more serious. The consequences of excessive application of chemical fertilizer...
