In the spring of March, vegetable farms were even more busy. Greenhouse tomatoes, peppers, eggplants, and cucumbers began to be planted, while cucumbers, zucchini, and tomatoes used in overwintering greenhouses should pay attention to dressing, watering, and pest control during this period. This period is a crucial period for striving for yield and benefits. Grasping the correct fertilization techniques and selecting the appropriate fertilizer type are the key factors. Fertilizer can promote vegetable growth and increase yield and quality. However, not all fertilizers are suitable for application on vegetables. Ammonium nitrate and other nitrate nitrogen fertilizers should generally not be applied to vegetables All fertilizers containing nitrogen in the form of nitrate (NO3-) are nitrate-containing fertilizers, including ammonium nitrate, calcium nitrate, and sodium nitrate. Among them, ammonium nitrate has both NH4+ and NO3-, but it is customarily listed as nitrate nitrogen fertilizer. . After nitrate nitrogen fertilizer is applied to the vegetable field, the nitrate content in the vegetables will increase exponentially. Nitrate is easily reduced to nitrite in the human body. Nitrite is a highly toxic substance that is extremely harmful to the human body. Ammonium chloride, potassium chloride and other chlorinated fertilizers are not suitable for use in tomatoes, potatoes and other vegetables Ammonium chloride, potassium chloride, and compound (mixed) Hefei, special fertilizer, and formula fertilizer made of ammonium chloride and potassium chloride are not suitable for use in vegetables such as tomatoes and potatoes. Because the chloride ion can reduce the starch and sugar content of vegetables, the quality of the vegetables will be reduced and the yield will be reduced. Moreover, the residual of chloride ions in the soil will lead to acidification of the soil, which will cause decalcification of the soil and cause soil compaction. Leafy vegetables such as spinach and rape must not be sprayed with nitrogen fertilizer When nitrogen fertilizer is sprayed on the leaves of vegetables, the ammonium ions are easily absorbed into leaves after contact with air, and the short growing period of leafy vegetables makes it easy to accumulate nitrate in the leaves. Therefore, avoid spraying nitrogen fertilizer on leaves of vegetable vegetables. The vegetable applies micro-fertilizer to avoid excessive, should determine the amount of soil testing Fertilizer can promote high quality and high yield of vegetables, but the demand for trace elements in vegetables is very small. Excessive application of trace element fertilizer not only causes waste, but also produces poison to the crop and pollutes the environment. The amount of ferrous sulfate per mu cannot exceed 3.25 kg. The consumption of manganese sulfate and manganese chloride per month cannot exceed 2.05 kg. Copper sulfate cannot exceed 2 kg per mu. The amount of borax and boric acid per mu cannot exceed 1.25 kg.
