Compound microorganism selenium-rich fertilizer special for rice

Abstract

The invention discloses a compound microorganism selenium-rich fertilizer special for rice. The fertilizer is prepared from urea, monoammonium phosphate, ammonium sulfate, potassium sulfate, bentonite, strains, nano-powder, rooting powder, fertilizer efficiency increasing essence, an SAD-resistance inducer 1, a cell growing agent, multiplex trace elements, a biological regulator, medical stone powder, selenium powder, a biological water retaining agent, chlorine sodium nitrate, sodium naphthalene-1-acetate, ammonium molybdate, DA-6, KT-30, a water-soluble polymer called Guantian, prohexadione calcium, cryptoxanthin, KT-+benzene mycin, food residues, an HDDE-sustained release biological controlled release agent, chlormequat chloride, brassinolide and potassium nitrophenolate by weight. By means of the fertilizer, the absorption speed of crops is high, the selenium content of fruits is stable, the content of heavy metals and non-organic impurities is extremely low, regeneration of crops is fast, the growth vigor is good, the tillering quantity is large, stalks are thick and strong, the rate of blighted grains is small, the yellowing performance is good, crops have disease resistance, drought resistance, cold resistance and lodging resistance, and various diseases are prevented.

Description

technical field [0001] The invention relates to the technical field of fertilizers for crops, in particular to a special compound microbial selenium-enriched rice fertilizer. Background technique [0002] At present, rice is the most important food crop for our people, and the planting area of ​​rice is constantly expanding. The nutrients in rice are closely related to human health. Therefore, the production of safe organic rice is a cause related to human health. To ensure rice production , quality and food safety, pollution-free fertilizer is the premise, but in the prior art, rice fertilization is mostly based on conventional single-substance fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. The application of organic fertilizers on the soil lacks the decomposition of beneficial microorganisms, so that the nutrients can not be fully released for the absorption and utilization of crops, resulting in low fertilizer absorption rate and poor fertilizer...

[0002] At present, rice is the most important food crop for our people, and the planting area of ​​rice is constantly expanding. The nutrients in rice are closely related to human health. Therefore, the production of safe organic rice is a cause related to human health. To ensure rice production , quality and food safety, pollution-free fertilizer is the premise, but in the prior art, rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. Applying organic fertilizers on the soil, due to the lack of decomposition of beneficial microorganisms, the nutrients in them cannot be fully released for absorption and utilization by crops, resulting in low fertilizer absorption rate and poor fertilizer efficiency, especially the absorption effect of selenium is not ideal
