Agricultural organic fertilizer and preparation method thereof

Abstract

The invention provides agricultural organic fertilizer. The agricultural organic fertilizer is prepared from, by weight, 35-45 parts of straw, 20-30 parts of plant ash, 10-15 parts of cow dung, 10-12 parts of phosphorus citric acid residues, 5-8 parts of Chinese pulsatilla roots, 3-5 parts of chalcanthite, 4-7 parts of big-leaf osbeckia nepalensis, 6-9 parts of hydrargyri oxydum rubrum, 1-2 parts of dyetree fruits, 4-8 parts of diversifolious pricklyash leaf seeds, 2-5 parts of quassia roots, 6-8 parts of brucea leaves, 5-7 parts of eucalyptus exserta leaves, 2-4 parts of copperas and 0.4-0.8 part of selinum japenious seeds. The agricultural organic fertilizer is fully ripened, reduces diseases and pests, has a sterilization effect, is high in nutrient content and can be preserved for a long time.

Description

technical field [0001] The invention relates to an agricultural organic fertilizer. Background technique [0002] Organic fertilizers are carbon-containing materials mainly derived from plants and (or) animals, and applied to the soil to provide plant nutrition as its main function. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production. Regardless of the history of biofertilizers, microbial agents continue to move forward. Since the 1...

AI Technical Summary

Problems solved by technology

Regardless of the history of biofertilizers, microbial agents continue to move forward. Since the 1980s, people have paid great attention to biofertilizers for the environment and crops because such products can effectively solve existing problems. Some problems, especially non-pollution and elimination of environmental pollution, therefore, it is very difficult to develop a kind of fertilizer that not only has the function of fertilizer, but also has the ability to eliminate environmental pollution. The difficulty is that a kind of microorganism has the function of providing plant nutrition Such as nitrogen fixation genes, etc.), but they may not necessarily have the ability to decompose pollution (that is, genes that decompose substances), it is very difficult to implement gene transfer, and a huge investment is required; there are many types of soil pollutants, and there are now more than 105 kinds of substances It has caused pollution to the environment. These pollutants have different structures and chemical compositions, so it is impossible to mix 105 kinds of microorganisms to make preparations, and gene transfer is even more difficult to achieve; the principles and principles of biopesticides and bioherbicides There are huge differences in bacterial species. In principle, one bacteria has one purpose, so it can only be made into a single bacterial agent, and it takes a long time to work; some of the bacterial agents in biological fertilizers are not typical soil microorganisms. When they are made It is difficult for the fungicide to survive after being applied to the soil, and it usually only has a shelf life of 3 months before use

[0003] At present, the existing organic fertilizers have a short storage time and are prone to mildew and deterioration, thus affecting fertilizer efficiency.
