Method for preparing insect repelling organic fertilizer

Abstract

This invention discloses a method for manufacturing an insecticidal organic fertilizer. The fertilizer is composed of human or animal excrement, straw powder, tree leaves, wine lees, drug residues, sawdust, edible fungi residues, furfural residues, lime powder, fermentation agent, phosphorus- and potassium-leaching bacteria, tobacco powder, Ricinus communis leaf powder, Zanthoxylum cake powder, Datura and Strychnos nuxvomica. The fertilizer has such advantages as wide raw material resources, low cost, convenient usage, abundant nutrition, low fertilizer application amount, high efficiency, no toxicity, no pollution and no residues.

Description

technical field [0001] The invention relates to a preparation method of an insect-repelling organic fertilizer. Background technique [0002] Fertilizers and pesticides are indispensable materials for agriculture, and people are becoming more and more aware of the harm of pesticides to people. Extensive use of chemical fertilizers and pesticides not only causes serious environmental pollution but also reduces the quality of agricultural products. Therefore, the use of organic fertilizers and low-residue pesticides is increasingly recognized by people. The quality of fertilizers determines the quality of crops. The current basic status of organic fertilizers is as follows: [0003] 1. Undecomposed organic fertilizer: This kind of fertilizer is mostly farmyard manure, which is human or livestock manure. However, these fertilizers are not fully decomposed, and they will cause burning of seedlings and broken ridges after being applied. Because the ma...

Problems solved by technology

However, these fertilizers are not fully decomposed, and they will cause burning of seedlings and broken ridges after being applied. Because the manure contains eggs and pathogenic bacteria, it is easy to cause soil-borne diseases after being applied to the soil, which will endanger the growth of crops; The use of chemical pesticides, which in turn makes the pesticide residues in agricultural products exceed the standard, endangering people's health

Therefore, undecomposed organic fertilizers should not be used

[0004] 2. Indigenous fermentation: that is to cover livestock and poultry manure with plastic cloth and carry out anaerobic natural fermentation. This kind of fermentation takes a long time, and some take several months; second, the fermentation temperature is low and uneven. Insect eggs, pathogenic bacteria and weed seeds in livestock and poultry manure cannot be completely killed, and the phenomenon of burning roots and seedlings will still occur after being applied to the soil

[0005] 3. Drying chicken manure: drying chicken manure is to put raw chicken manure directly into the drying furnace for drying, and then apply it to the farmland. This method is extremely undesirable, because drying only removes a large amount of water in the raw manure , is not a harmless treatment. There are a lot of insect eggs and pathogenic bacteria in the dried chicken manure. Severely polluted and do not meet environmental protection requirements, most of them have been ordered to close down by the local government

At present, there is no multifunctional fertilizer that combines organic fertilizers, biological fertilizers, insect repellent plants and Chinese herbal extracts
