Problems solved by technology

[0003] In rice production, due to some unreasonable factors in the use of fertilizers, the application of nitrogen fertilizers is emphasized during rice planting, and the application of organic fertilizers and micro-fertilizers is ignored. The ratio of organic fertilizers to inorganic fertilizers is seriously unbalanced, unreasonable fertilization and improper fertilization methods lead The low utilization rate of fertilizers leads to malnutrition of rice, lodging, yield reduction, and quality decline. At the same time, the soil properties of cultivated land deteriorate and seriously pollute the environment.
The potential of rice production and the efficiency of natural resources such as soil cannot be brought into full play, which limits the increase in rice yield, ultimately affects the economic benefits of farmers and brings a series of ecological and environmental problems

Abstract

The invention discloses a multi-element rice special fertilizer which is prepared from the following raw materials by weight: 60-80 parts of livestock manure, 30-40 parts of humic acid, 20-30 parts ofplant ash, 40-50 parts of urea , 15 to 25 parts of monoammonium phosphate, 30 to 40 parts of potassium dihydrogen phosphate, 20 to 30 parts of potassium chloride, 5 to 7 parts of boric acid, 4 to 6 parts of magnesium sulfate, 3 to 5 parts of trace elements, 2 to 4 parts of cross-linked chitosan and 2 parts of sodium dehydroacetate. The invention also discloses a preparation method of the multi-element rice special fertilizer. The multi-element rice special fertilizer prepared by the method has the advantages of comprehensive nutrition, and excellent performances of increasing of production and income, improving of nutrient utilization rate, and fully satisfying the nutrient needs of rice, can meet the needs of the rice in the whole growth period by once fertilizing, saves manpower, improves soil ventilation and fertilizer absorption and water retention properties, promotes the stable growth of rice plants and significantly increases the yield and quality of the rice.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a special multi-element rice fertilizer and a manufacturing method thereof. 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. . Rice is one of the most important food crops in the world. With the rapid increase of the global population, increasing rice production has become an urgent issue. Among them, fertilizer plays an important role in improving the yield of rice. Reasonable fertilization, on the one hand, can coordinate the contradiction between rice growth's demand for nutrient elemen...
