1. Scope This standard specifies the rules for the rational use of pollution-free vegetable fertilizers.
This standard applies to the rational use of fertilizers in the production of pollution-free vegetables in Huludao.
2. Definition
This standard uses the following definition.
2. 1 Farmhouse Fertilizer refers to the fertilizer that is used locally and collected locally, and contains a large amount of biological substances, animal and plant residues, excreta, biological waste and other substances. Including compost, manure, manure, biogas fertilizer, crop straw fertilizer, mud fertilizer, cake fertilizer.
2.1.1 Composting An organic fertilizer made up of various types of straw, deciduous, mountain green, lake grass, human and animal waste as raw materials, mixed with a small amount of soil.
2.1. 2 Fertilizers All materials of compost are basically the same as compost, but they are fermented under flooding conditions (animality).
2.1.3 manure refers to the manure and straw of the pigs, cattle, horses, sheep, chickens, ducks and other livestock and poultry.
2.1.4 Biogas Fertilizer In a closed biogas tank, organic matter is decomposed under anaerobic conditions to produce by-products of biogas, including biogas liquid and residue.
2.1.5 Green manure The use of cultivated or wild green plants as fertilizers is mainly divided into two major categories: legumes and non-legumes.
2.1.6 Crop straw fertilizer The crop straw wheat straw, straw, corn stover, bean straw, rapeseed straw, etc. are used as raw materials. Under suitable conditions, the elements contained in the straw crop are mineralized and returned to the soil. Medium, fertilizer for the absorption and utilization of crops.
2.1.7 Mud Fertilizer Undegraded river mud, pond mud, ditch mud, port mud, lake mud and other fertilizers that are decomposed by anaerobic microorganisms.
2.1.8 Cake Fertilizer A fertilizer made from various residues containing oil and pressed to remove oil. Such as: rapeseed cake, cotton seed cake, bean cake, sesame cake, castor cake, etc. 2.2 Commercial fertilizers According to national regulations, the national fertilizer department is required to manage the fertilizers sold in the form of commodities. Including commercial organic fertilizer, humic acid fertilizer, microbial fertilizer, organic compound fertilizer, inorganic (mineral) fertilizer, foliar fertilizer.
2.2. 1 Commercial organic fertilizer refers to commercial fertilizer produced by processing a large amount of biological materials, animal and plant residues, excreta, biological waste and other materials.
2.3. 2 Humic acid fertilizers 2.4. Fertilizers containing plant nutrients are processed by using peat carbon (grass carbon) containing humic acids, lignite, and weathered coal.
2.2.3 Microbial Fertilizer Microbial preparations cultured with specific microbial species. According to the microbial fertilizer to improve the different nutrients of plants, it can be divided into: rhizobial fertilizer, nitrogen-fixing fertilizer, phosphorus bacterial fertilizer, silicate bacterial fertilizer, and compound microbial fertilizer.
2.2.4 organic compound fertilizer (semi-organic fertilizer)
Fertilizer made by mechanical mixing or chemical reaction of organic fertilizer and inorganic fertilizer (the ratio of organic fertilizer to inorganic nitrogen does not exceed 1:1)
2.2.5 Inorganic (mineral) fertilizers Minerals are produced by physical or chemical industries and are classified as fertilizers in the form of inorganic salts.
2.2.6 Foliar Fertilizers Fertilizers that are applied to the leaves of plants and can be absorbed by them. Foliar fertilizers must not contain chemically synthesized growth regulators. It includes foliar fertilizers containing trace elements and foliar fertilizers containing plant growth aids.
2.3 Other fertilizers 2.3.1 Foods that do not contain synthetic additives, organic by-products of the textile industry.
2.3.2 Waste materials including organic residues such as preservative-free fish residue, beef wool waste, bone meal, amino acid residue, bone glue waste, livestock processing waste, and sugar factory waste.
2.4 Non-polluted vegetable production data refers to the production materials that have been identified by specialized agencies and meet the requirements for the production of pollution-free vegetables and are officially recommended for the production of pollution-free vegetables.
3. 1 Try to use the fertilizer in Chapter 3 of this standard.
3.2 If it is necessary in production, it is allowed to use chemical synthetic fertilizers in 3.3 and 3.4 of the standard, but the nitrate nitrogen fertilizer is prohibited.
3.3 Fertilizer must be applied in combination with organic fertilizer. The ratio of organic nitrogen to inorganic nitrogen is 1:1, and the last top dressing must be carried out 30 days before harvest.
3.4 Fertilizer can be applied in combination with organic fertilizer and microbial fertilizer. The last top dressing was carried out 30 days before the harvest.
3.5 Urban domestic garbage should be treated in a harmless manner and the quality can meet the requirements.
3.6 The organic fertilizer applied per mu shall not exceed 60 kg, of which the ratio of nitrogen: phosphorus: potassium should be 1:0.8:0.5, the leafy vegetables should be 2:1:0.5, and the root vegetables should be 1:0.8:0.8. Do not use potassium chloride.
3.7 Manure must be fully decomposed before use.
3.8 Cake fertilizer is used preferentially, and the unsoiled cake fertilizer is prohibited.
3.9 The quality of foliar fertilizer should meet the relevant provisions of GB/T17419 or GB/T17420, diluted according to the instructions for use, and sprayed two or three times during the crop growth period. The last use of a single variety of foliar and inorganic fertilizers should be carried out 12 days before harvest, and the foliar fertilizer and other pesticides (bactericides, etc.) should be used for the last 15 days before harvest.
This standard applies to the rational use of fertilizers in the production of pollution-free vegetables in Huludao.
