Composite microelement fertilizer containing chlorella and paenibacillus, preparation and applications thereof

Abstract

The invention relates to the field of microbial fertilizer, and specifically relates to a composite microelement fertilizer containing chlorella and paenibacillus. The composite microelement fertilizer is prepared by mixing chlorella sp. and paenibacillus sp. together. The composite microelement fertilizer can prominently promote the growth of plants, and is capable of enhancing the disease resistant performance of plants; moreover, the using amount o f chemical fertilizer and chemical pesticide is effectively reduced, the quality of agricultural products is obviously improved, and thus the composite microelement fertilizer can be used and popularized in agricultural production.

Description

Technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a compound micro-fertilizer containing chlorella and nitrogen-fixing bacillus and its preparation and application. Background technique [0002] At present, the excessive use of chemical fertilizers and pesticides in vegetables, fruits and field crops in my country has led to an increase in the residues of nitrite and pesticides in vegetables and fruits, which has seriously threatened people's health. At the same time, excessive use of chemical fertilizers causes the reduction of soil organic matter, the deterioration of soil structure, and the intensification of desertification. Long-term excessive application and dependence on chemical nitrogen fertilizers have brought huge negative effects on agricultural production and the ecological environment. Long-term excessive application of chemical fertilizers, especially chemical nitrogen fertilizers, on the one hand, the accumulatio...

AI Technical Summary

Problems solved by technology

[0002] At present, the excessive use of chemical fertilizers and pesticides in vegetables, fruits and field crops in my country has led to an increase in nitrite and pesticide residues in vegetables, fruits, etc., which has seriously threatened people's health

At the same time, the excessive use of chemical fertilizers leads to the reduction of soil organic matter, the deterioration of soil structure, and the intensification of desertification.

Long-term overuse and dependence on chemical nitrogen fertilizers have brought huge negative impacts on agricultural production and the ecological environment

Long-term excessive application of chemical fertilizers, especially chemical nitrogen fertilizers, on the one hand, the accumulation of nitrates tends to lead to soil acidification and salinization, and the decline in soil microbial activity; Exceeding the standard of nitrate seriously endangers human health. On the other hand, it increases the risk of water pollution and has become an important factor restricting the sustainable development of agriculture.
