Manganese silicon fertilizer dedicated to rice and preparation method thereof

Abstract

The invention discloses a manganese silicon fertilizer dedicated to rice. The manganese silicon fertilizer is prepared from the raw materials like electrolytic manganese residues, fly ash, kieselguhr, humic acid, livestock manure, molasses, compound microelements, vinegar residues, straw and compound zymophyte. The invention further discloses a preparation method of the fertilizer. The preparation method comprises the steps of crushing, fermentation, drying granulating, and the like. According to the manganese silicon fertilizer dedicated to rice, various symptoms caused by the fact that rice lacks manganese are solved, lodging resistance and disease and pest resistance of rice can be strengthened through silicon elements, growing gestures of functional leaves are improved, the leaf area is increased, photosynthetic intensity is improved, accumulation of dry matters is facilitated, and the fruiting rate is increased; manganese and silicon synergistically act to promote growth and development of rice, the yield is increased, and the quality is improved; micronutrient elements of rice fields where chemical pesticides are utilized for a long time are supplemented, and the soil structure can be improved; and fertilizer efficiency is long, and the manganese silicon fertilizer has the function of regulating soil for a long time.

Description

technical field [0001] The invention relates to the field of pesticides and fertilizers, in particular to a special manganese and silicon fertilizer 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 germination and seedl...

Problems solved by technology

At present, chemical fertilizers are used in most planting industries in my country. Although they have a certain effect on increasing production and income, long-term use will cause soil acidification and compaction, resulting in poor water retention, fertilizer retention, and poor air permeability; secondly, it will cause excessive accumulation of harmful chemical residues in the soil. Severe pollution occurs, reducing the utilization rate of fertilizers, and most of the fertilizers are discharged into rivers and lakes or residual soil and crops, resulting in waste of resources, destroying the agricultural ecological environment, and endangering human safety.
