1. Application of Ammonium Nitrate Green leafy vegetables such as Chinese cabbage, Chinese cabbage, Chinese chive, celery, and spinach have a short growing period and are easily absorbed by nitric acid nitrogen fertilizer, leading to excessive nitrate content in vegetables. Green leafy vegetables should not be applied ammonium nitrate.
2. The spraying of pure nitrogen fertilizer on green leafy vegetables should not be used to spray nitrogenous fertilizer such as urea or ammonium sulfate, nor should it be sprayed with human urine. Urea, ammonium sulphate or human urine are sprayed on the foliage, and the nitrate content will increase significantly, affecting human health.
3, can not be immediately after the application of urea irrigation urea can only be transformed into ammonium carbonate or ammonium bicarbonate can be absorbed and used by vegetable roots, or soil adsorption and preservation. Immediately after the urea is applied, it will be filled with water or rain, and the amide nitrogen will be lost along with the water, causing loss of nitrogen nutrients. Generally urea is applied 5-7 days before irrigation to avoid unnecessary nitrogen loss.
4. Do not apply ammonium sulfate multiple times in acidic soils or calcareous fields. If ammonium sulfate is used multiple times in a row, the acid soil will become more acidic; the calcareous soil will cause soil compaction and hinder the normal growth of vegetables.
5. It is not suitable to apply Ammonium Bicarbonate Ammonium Bicarbonate to the water in the absence of water in vegetable fields. It is extremely unstable and volatile. Especially in the case of drought and water shortage in vegetable fields, the loss is more serious. For the application of ammonium bicarbonate in vegetable fields, regardless of whether it is used as a base fertilizer or topdressing, deep application should be carried out under the condition of moist vegetable fields, and the soil shall be covered immediately after application.
6. Do not use too much phosphate fertilizer in the vegetable fields. If you use phosphate fertilizers for a large number of years, excessive supply of phosphate fertilizers, especially in the case of more than 40 kilograms of mu, will cause serious harm, which will seriously affect the growth and development of vegetables, cause premature aging of vegetables, and poor growth. , The output is reduced and the quality is deteriorated. General Mushi 15-20 kg is appropriate.
7. Green leafy vegetables should not be used to produce human excrement, especially in hospitals, stations, docks, restaurants and public toilets, containing a variety of infectious bacteria and parasite eggs. If such manure is directly applied to green leafy vegetables without being tampered with or treated, the vegetables will be seriously polluted and even cause the spread of various infectious diseases and parasitic diseases. The manure can be applied after the detoxification treatment such as sealed stacking, biogas digester fermentation, and drug treatment.
8. The livestock and poultry manure should be used for pigs and cattle after the stacking. The feedstuffs are selected from crop straws and weeds. The straws and weeds are mixed with a lot of weed seeds. The weed seeds in manure manure are very strong. The fecal ring fertilizers are brought into the vegetable field and can still germinate, causing great harm to the vegetables. Sputum fertilizer should be taken out of the ring, after high-temperature stacking, to kill weed seeds and parasite eggs, pathogenic bacteria in livestock manure. Generally, natural heaping can be applied for about 2 months. If the biological starter is used to treat the stack for 10 days, it can fully decompose.
