Special compound fertilizer for rice as well as preparation method and applying method of special compound fertilizer

Abstract

The invention discloses a special compound fertilizer for rice. The special compound fertilizer is prepared from the following raw materials of 40-50 parts of an organic fertilizer,10-15 parts of straw, 20-30 parts of a nitrogenous-phosphorus-and potassium fertilizer, 3-5 parts of calcium superphosphate, 3-5 parts of ferrous sulfate, 3-5 parts of zinc sulfate, 3-5 parts of hydroxymethylcellulose, and 0.3-0.5 part of a microorganism microbial population. The invention further discloses a preparation method and applying method of the special compound fertilizer. Through a reasonable fertilizer formula, the simple and easy preparation method and the simple and easy applying method, the finally-obtained fertilizer is rich in various constants and micro nutrients, required by the rice. The fertilizer has remarkable effects in the respects of ecological microbial population adjustment, nutrient feeding, fertilizer utilization and the like of soil, so that the fertilizing amount is greatly reduced, and the cyclic utilization, the low carbon and the high efficiency of the straw are realized. Soil organic matters are markedly increased, the farmland fertility is persistently maintained, the agriculture point source pollution is reduced, the farmland biological diversity is effectively protected, the water resources and the ecological environment of local valleys are effectively protected, and the agricultural sustainable development is promoted.

Description

technical field [0001] The invention relates to a special compound fertilizer for rice and its preparation method and application method, which belong to the technical field of agricultural science and technology. Background technique [0002] With the popularization and application of high-yielding and high-quality rice varieties and the development of cultivation techniques in China, rice production has maintained growth for more than ten consecutive years. In addition to fine varieties, chemical fertilizers and pesticides have made important contributions. However, the excessive and unreasonable and timely use of chemical fertilizers and pesticides, and the low utilization efficiency of chemical fertilizers and pesticides have brought about soil compaction, acidification, pesticide residue toxicity, increased resistance (resistance) of pests and diseases, the occurrence of secondary pests, environmental pollution and resource pollution. A series of problems, such as waste,...

Problems solved by technology

However, the excessive and unreasonable and timely use of chemical fertilizers and pesticides, and the low utilization efficiency of chemical fertilizers and pesticides have brought about soil compaction, acidification, pesticide residue toxicity, increased resistance (resistance) of pests and diseases, the occurrence of secondary pests, environmental pollution and resource pollution. A series of problems, such as waste, seriously threaten the quality and safety of rice products in my country and the safety of the agricultural ecological environment

[0003] At present, most of the research in my country on improving fertilizer utilization efficiency and reducing fertilizer usage is focused on changes in fertilization methods, such as: soil testing formula fertilization technology, precision fertilization technology, balanced fertilization technology, nitrogen fertilizer operation optimization technology, etc., to a certain extent The utilization rate of fertilizer has been improved, but it has not yet reached a good level in reducing the amount of fertilizer and improving the soil environment. Therefore, it is urgent to effectively improve the formula, preparation method and application method of fertilizer.
