Special manganese fertilizer for paddy rice and preparation method of manganese fertilizer

Abstract

The invention discloses a special manganese fertilizer for paddy rice. The manganese fertilizer is prepared by the following raw materials: electrolytic manganese residues, kieselguhr, humic acid, organic raw materials, livestock excrement, EDTA iron chelate, copper tartaric acid complex, molybdenum amino acid complex, zinc amino acid complex, boron amino acid complex, manganese amino acid complex, and the like. The invention also discloses a preparation method of the special manganese fertilizer for the paddy rice. The preparation method comprises the steps of pulverizing, fermenting, drying and granulating, and the like. The manganese fertilizer is prepared through fermentation of the electrolytic manganese residues and natural organic matters, the content of manganese in soil is supplemented effectively, and the growth development problem of the paddy rice arising from manganese deficiency is solved; the manganese fertilizer has a micronutrient element supplementing function on the paddy field using pesticides and fertilizers for a long term; complex metal elements required by various paddy rice are added, are stable in a soil environment, and can be absorbed employed by plant root systems easily; raw material sources of the manganese fertilizer are wide; the preparation method is simple and convenient, and has great popularization value.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a special manganese 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 seedling...

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 air permeability, resulting in the lack of trace elements in the soil. It is the lack of manganese, which affects the growth and development of crops and the quality of rice
