(1) Hi-vegetable vegetables are rich in fertilizers. Vegetables absorb much more nutrients than rice. Compared with wheat, nitrogen uptake was 40% higher, phosphorus uptake was 20% higher, potassium uptake was 1.92 times higher, and calcium uptake was 4.3 times higher. Coupled with high yields of vegetables, more glutinous crops in the year, more fertile soil conditions are required, and the impact of nutrient deficiency on vegetable yield and quality is much greater than that of conventional field crops.
(2) Vegetable roots have strong absorption capacity.
(3) Vegetable is a nitrogen-like fertilizer plant that is sensitive to ammonium nitrogen fertilizer. Nitrate nitrogen fertilizer (such as sodium nitrate, calcium nitrate), vegetables absorb quickly and increase production significantly. However, over-application of nitrate fertilizers, it is easy to accumulate a large amount of nitrate in vegetables, and excessive amounts of nitrate will be converted into nifedipine peptides by humans. N-nitrosopeptides can harm human health. If the ammonium nitrogen fertilizer (such as ammonium sulfate, ammonium bicarbonate, ammonium chloride) is applied too much, serious fertility disorders will occur. Therefore, in the cultivation of vegetables, attention should be paid to the proportion of nitrogen fertilizers in various states. Ammonium nitrogen fertilizer should generally not exceed 1/4-1/3 of the total amount of nitrogen fertilizer.
(4) Vegetable roots have high oxygen demand for respiration. The condition of soil ventilation has a great influence on the absorption function of the root morphology. Vegetable cultivation, cultivator is an important field technology.
(5) Most vegetables absorb large amounts of potassium. Among the mineral elements absorbed by vegetables such as eggplants, melons, root vegetables, and cabbage and leafy vegetables, potassium nutrition accounts for the first place among various mineral fertilizers.
(6) Vegetables are hi calcium, the amount of boron is higher than other crops, and it will also enrich various mineral elements in the soil. Therefore, urban garbage containing large amounts of heavy metal salts cannot be used as fertilizer in vegetable fields.
