Manganese-iron-silicon fertilizer special for rice and preparation method thereof

Abstract

The invention discloses a manganese-iron-silicon fertilizer special for rice. The manganese-iron-silicon fertilizer special for the rice is prepared from electrolytic manganese residues, humic acid, straw, a yeast waste solution, mushroom bran, an iron-compound, coal ash, clay, compound microelements and other raw materials. The invention further discloses a preparation method of the manganese-iron-silicon fertilizer special for the rice. The preparation method of the manganese-iron-silicon fertilizer special for the rice comprises the steps of smashing, fermentation, drying, granulation and the like. The manganese-iron-silicon fertilizer special for the rice solves various symptoms caused by the fact that the rice lacks manganese; the coal ash and the clay contain a large amount of silicon, when the silicon is applied to the rice, the lodging resistance and the disease and pest resistance can be enhanced, and the setting rate can be improved; the fertilizer contains a large amount of iron, so that growth and development of the rice can be promoted; through the synergistic effect of the manganese, the iron and the silicon, the yield and the quality of crops are remarkably improved; and meanwhile, the manganese-iron-silicon fertilizer is rich in humic acid and other natural organic fertilizer, formation of a soil granular structure can be promoted, the soil breathability is improved, so that the fertilizer retaining capacity and the water retaining capacity of the soil are improved, and the phenomena of soil agglomeration and soil salinization can be effectively reduced.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a ferromanganese-silicon fertilizer specially used for rice and a preparation method thereof. Background technique [0002] Manganese is an indispensable micronutrient element for rice growth. Manganese deficiency in rice will lead to abnormal growth and development, and the number of tillers, spike rate, grain number per panicle, thousand-grain weight and yield are all lower than normal rice. The main factors affecting manganese content in soil are soil pH value (pH=6.5 is the limit), soil texture, redox potential, humidity, organic matter content, aeration, organic matter and clay content. In terms of rice physiological functions, manganese is also an important factor that affects rice photosynthesis, affects water photolysis and electron transfer, regulates enzyme activity, promotes nitrogen metabolism, regulates redox status in plants, and promotes seed germ...

Problems solved by technology

At present, most rice planting in my country uses a large amount of chemical fertilizers. Although it has a certain effect on increasing production and income, the acidification and compaction of the soil caused by long-term use lead to poor water retention, fertilizer retention, and poor air permeability, resulting in a lack of trace element loss in the soil. Especially the lack of manganese and iron, which affects the growth and development of crops and the quality of rice
