Fermented biological organic fertilizer and preparation method thereof

Abstract

The invention discloses a fermented biological organic fertilizer based on oilseed rape residue and livestock and poultry manure and a preparation method of the fermented biological organic fertilizer. 80% of sheep manure, 10% of cow dung, 2% of chicken manure, 2% of pig manure, 2% of oilseed rape residue, 0.34% of wheat bran and 0.33% of brown sugar are used as main materials, 0.33% of zymophyteand 3% of humic acid are used as auxiliary materials; and turning, fermenting, decomposing, stirring, cooling, crushing, sieving and packaging are performed so as to prepare the fertilizer. When the organic fertilizer is applied to agricultural production, the application range of the fertilizer is wide; and the organic fertilizer can be applied to various fields of crop planting, Tibetan medicinal material planting, flower plant and fruit and vegetable planting.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a bio-organic fertilizer fermented with rape residue and livestock manure, and a preparation method of the fertilizer. Background technique [0002] Now people have higher and higher requirements on the quality of life and food quality, and are eager to obtain food with good taste and good nutrition. Therefore, it has become a fashion to pursue pure natural and pollution-free healthy food. However, due to the excessive development of agriculture, especially the long-term use of simple chemical fertilizers, the soil has not been properly replenished with organic matter, resulting in a decline in soil quality, which has far-reaching effects on promoting the development of organic food, improving human health, and increasing the export of agricultural products. With the continuous improvement of people's living standards, the people of our country have shifted...

AI Technical Summary

Problems solved by technology

[0004] At present, there are still some defects in the common bio-organic fertilizers, such as low stack retting temperature, which cannot kill harmful bacteria, especially livestock and poultry manure such as sheep manure, cow manure, chicken manure and pig manure. If it is not perfect, it will cause burning of seedlings due to the large amount of urokinase in the feces. Long-term use may even cause no grass to grow, which will have a serious adverse effect on agricultural production.
