5 usage rules
Fertilizer use must meet the crop's need for nutrient elements and return sufficient organic matter to the soil to maintain or increase soil fertility and soil biological activity. All organic or inorganic (mineral) fertilizers, especially those rich in nitrogen, can be used without adverse consequences on the environment and crops (nutrition, taste, quality and plant resistance).
5.1 Principles for the Use of Fertilizer for Production of AA Grade Green Food
5.1.1 The type of fertilizer that must be used in 4.1 is forbidden to use any chemical synthetic fertilizer.
5.1.2 It is forbidden to use municipal wastes and sludges, hospital wastes and industrial waste containing harmful substances (such as toxic gases, pathogenic microorganisms, heavy metals, etc.).
5.1.3 Localities can adopt the form of returning straw, returning land to the field, directly returning land to the field, and returning to the field.
5.1.4 Rational use of green manure by covering, overturning, stacking, etc. Green manure should be overturned at flowering stage, and the buried depth should be about 15cm. Sowing or transplanting can only be carried out 15-20 days after pressing.
5.1.5 Decomposed biogas liquids, residues and manure urine can be used as top dressing. Do not use unfamed human waste.
5.1.6 Cake fertilizer is preferred for fruits, vegetables, etc. It is forbidden to use uncomminuted human waste.
5.1.7 The quality of foliar fertilizers should meet the technical requirements of GB/T17419 or GB/T17420 or B3 in Appendix B. Diluted according to the instructions for use. Spray twice or three times during the crop growth period.
5.1.8 Microbial fertilizers can be used for seed dressing, and can also be used as base fertilizer and top dressing. When using, operate strictly according to the requirements of the instruction manual. The number of viable bacteria in microbial fertilizers shall comply with the provisions of 4.1 and 4.2 of NY227-1994.
5.19 The quality of calcined phosphate and potassium sulfate used in inorganic (mineral) fertilizers shall meet the requirements of Appendix B.
Fertilizer Use Principles for Grade 5.2A Green Food
5.2.1 The fertilizer type 4.2 must be used. If the type of fertilizer in 4.2 does not meet production requirements, chemical fertilizers (nitrogen, phosphorus, potassium) are allowed to be used according to the requirements of 5.2.2 and 5.2.3. However, the use of nitrate nitrogen fertilizers is prohibited.
5.2.2 Fertilizers must be applied in conjunction with organic fertilizers. The ratio of organic nitrogen to inorganic nitrogen does not exceed 1:1. For example, 1,000 kg of high-quality stubble fertilizer and 10 kg of urea (fertilizer as basal fertilizer and urea can be used as base fertilizer and top dressing). The last top dressing of leafy vegetables must be carried out 30 days before harvest.
5.2.3 Fertilizer can also be combined with organic fertilizer and compound microbial fertilizer. Fertilizer 1000kg, urea 5-10kg or diammonium phosphate 20kg, compound microbial fertilizer 60kg (fertilizer as base fertilizer, urea, diammonium phosphate and microbial fertilizer as base fertilizer and topdressing). The last top dressing must be done 30 days before harvest.
5.2.4 The municipal solid waste must be detoxified and its quality must meet the technical requirements of GB8172-1987 1.1. Limit the amount of farmland per hectare per year, sticky soil does not exceed 45,000 kg, and sandy soil does not exceed 30000 kg.
5.2.5 Straw returning: Same as in 5.1.3. It is also allowed to use a small amount of nitrogen fertilizer to adjust the ratio of carbon to nitrogen.
5.2.6 The other principles of use are the same as the requirements of 5.1.4-5.1.8.
6 Other provisions
6.1 Farmhouse Fertilizers for Producing Green Foods Composting, regardless of the type of raw materials (including human and animal waste, straw, weeds, peat, etc.), must be fermented at high temperatures to kill various parasite eggs, pathogens, and weed seeds. To achieve harmless health standards.
Fertilizers for farms are in principle used on-site for local production. Foreign farmhouse fertilizers should be used only after confirming that they meet the requirements. Commercial fertilizers and new fertilizers must pass the registration certification and production licenses of relevant state departments, and the quality indicators should meet the requirements of the relevant national standards.
6.2 When fertilization causes soil pollution, water pollution, or affects the growth of crops and agricultural products fail to meet sanitary standards, the fertilizer shall be stopped and reported to a special management agency. Food produced with it cannot continue to use the green food logo.
Second, convenience. It`s easy to lose keys and proximity cards. It`s troublesome to go out for a run, but mobile phones have become as important as our organs. When we use our mobile phones to get the QR code to open the door, we won`t lose them. Open it directly and swipe the door very convenient. If you share the key with your friends, you can set the number of unlocking times, the time limit for unlocking, etc. Anyway, who can open it and how long it will last is all up to you. No more silly going downstairs to pick up guests.
The third is to facilitate management. Its software has functions such as key sharing, management, access control record viewing, and role unlocking authority. It is suitable for places such as hotel apartments that require strict management of a large number of entrance guards and rooms.
Guidelines for the use of green food and fertilizer
Green food is pollution-free, safe, high-quality, nutritive food. The rational use of fertilizers, pesticides and other production materials is an important part of the production of green food. In order to ensure the quality of green foods and implement quality management of fertilizers for the production of green foods, this standard is formulated.
