The production of green foods also imposes various restrictions on the fertilizers used. So what are the fertilizers allowed?
1. Farmhouse fertilizer. Refers to fertilizers containing a large amount of biological substances, animal and plant residues, excreta, biological waste and other substances.
1. Composting. An organic fertilizer made up of various types of straw, deciduous, human and feces as raw materials and a small amount of soil.
2, fat fertilizer. The materials used are basically the same as the compost, but they are fermented under flooding conditions (animality).
3. Manure. It refers to the manure and straw of the pigs, cattle, horses, sheep, ducks and other livestock and poultry.
4. Biogas fertilizer. In a sealed biogas digester, organic matter is decomposed under anaerobic conditions to produce by-products of biogas.
5, green manure. The use of cultivated or wild green plants as fertilizers is mainly divided into two major categories: legumes and non-legumes, and legumes include mung beans, broad beans, and hibiscus. Non-legume green manure, the most commonly used are grasses, such as ryegrass; cruciferae, such as fertilizer radish.
6, crop straw. The crop straw contains a considerable amount of nutrient elements (n, p, k, ca, s, etc.), and under suitable conditions, through the action of soil microorganisms, after mineralization, it returns to the soil for absorption and utilization.
7, mud fertilizer. Uncontaminated river mud, pond mud, ditch mud, port mud, lake mud, etc.
8, cake fertilizer. Rapeseed cake, cottonseed cake, bean cake, sesame cake, peanut cake, castor cake, tea seed cake, etc.
2. Commercial fertilizers.
1. Commercial organic fertilizer. It refers to commercial fertilizers produced by processing a large amount of biological substances, animal and plant residues, excreta, biological wastes and other materials.
2. Humic acid fertilizer. Refers to fertilizers containing humic acids such as peat (pitch), lignite, and weathered coal.
3. Microbial fertilizer. It refers to the cultivation of active microbial preparations by using specific microbial strains, which can improve the nutrition of plants or produce plant growth hormone through the life activities of specific microorganisms, and promote plant growth.
4. Semi-organic fertilizer (organic compound fertilizer). A fertilizer made by mixing or combining organic and inorganic substances. After the harmless treatment of the poultry manure, add appropriate amount of fertilizers such as zinc, manganese, boron, molybdenum and other trace elements.
5. Inorganic (mineral) fertilizer. Minerals are produced by physical or chemical industries, and the nutrients are in the form of inorganic salts. Mineral potassium fertilizer and potassium sulfate; mineral phosphate fertilizer (phosphorus ore powder); calcined phosphate (calcium magnesium phosphate fertilizer, defluorinated phosphate fertilizer); limestone: limited to use in acidic soil; powdered sulfur fertilizer: limited to alkaline soil use.
6, foliar fertilizer. It refers to fertilizer that is sprayed on the leaves of plants and can be absorbed and utilized by them. Foliar fertilizers must not contain chemically synthesized growth regulators. Trace element fertilizer is a fertilizer formulated mainly from trace elements such as cu, fe, mn, zn, b, mo and beneficial elements. The plant growth auxiliary fertilizer is a fertilizer prepared by using natural organic fertilizer extract or fermenting liquid for inoculating beneficial fungi with some humic acid, alginic acid, amino acid, vitamins and sugar.
3. Other fertilizers.
1. Includes foods without synthetic additives and organic by-products from the textile industry.
2. Includes fish residue without preservatives, beef wool waste, bone powder, amino acid residue, bone glue residue, etc.
