Special ferromanganese fertilizer for rice and preparation method thereof

Abstract

The invention discloses a special ferromanganese fertilizer for rice. The special ferromanganese fertilizer for the rice is prepared through electrolytic manganese residues, kieselguhr, humic acid, pig blood, straws, yeast wastewater, mushroom residues, iron-containing compounds, compound trace elements and other raw materials. The invention also provides a preparation method of the fertilizer. The preparation method comprises the steps such as crushing, fertilizing, drying and pelletizing. With the adoption of the special ferromanganese fertilizer for the rice, various symptoms caused by manganese deficiency of the rice can be solved; in addition, the iron content of the fertilizer is increased, so that the requirement on the iron elements for the growth and development of the rice can be met, and moreover, the iron content in the rice can be increased, and as a result, the iron element of a human body can be supplemented to some extent after eating the rice. The fertilizer is used in match with azophoska so as to achieve the synergistic interaction effect; various indexes and the iron content of the rice are prior to those of similar varieties using common chemical fertilizers; the output increase effect is obvious, so that the economic benefit is high.

Description

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

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
