Odorless organic fertilizer and preparation technology thereof

Abstract

The invention provides an odorless organic fertilizer and a preparation technology thereof. The odorless organic fertilizer is prepared from the following raw materials: wheat straws, corn stalks, beanstalks, oilseed rape stalks, soybean meal, cottonseed meal, distillers grains, vinegar residues, cassava residues, sugar residues, cow dung, sheep dung, horse dung, black stump chalk and powdered rock phosphate, and in parts by weight the raw materials are as follows: 20-25 parts of wheat straws, 20-25 parts of corn stalks, 15-16 parts of beanstalks, 12-14 parts of oilseed rape stalks, 3-5 parts of soybean meal, 1-2 parts of cottonseed meal, 2-4 parts of distillers grains, 1-2 parts of vinegar residues, 3-5 parts of cassava residues, 1-2 parts of sugar residues, 8-10 parts of cow dung, 8-10 parts of sheep dung, 8-10 parts of horse dung, 30-35 parts of black stump chalk and 30-35 parts of powdered rock phosphate. The odorless organic fertilizer is thoroughly decomposed without heating the roots and buds, prevents plant diseases and insect pests from occurrence, and is high in nutrient content and odorless during fertilizing.

Description

technical field [0001] The invention relates to an odorless organic fertilizer and a preparation process thereof. Background technique [0002] Organic fertilizers are mainly derived from plants and (or) animals. They are applied to the soil to provide plant nutrition as carbon-containing materials. They are processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances. Substances, rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, not only can provide comprehensive nutrition for crops, but also have a long fertilizer effect, which can increase and update soil organic matter , promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, and are the main nutrients for green food production.

Problems solved by technology

[0003] 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 lies in: 1) a kind of microorganism has the ability to provide plant nutrition functions (such as nitrogen fixation genes, etc.), but 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; 2) There are many types of soil pollutants, and there are now 105 More than one kind of substances have 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; 3) Biopesticides and biological detoxification The principle and strains of herbicides are very different. In principle, one fungus has one purpose, so it can only be made into a single fungal agent, and it takes a long time to work; 4) Some of the fungal agents in biological fertilizers are not typical. It is difficult for soil microorganisms to survive when they are made into inoculants and applied to the soil, and they usually only have a shelf life of 3 months before use

[0004] At present, the existing organic fertilizers have a large odor when used, which has great harm to the environment. They are not decomposed and will attract underground pests when they are decomposed in the soil.
