Potassium sulfite is used as base fertilizer: potassium sulfite is mixed with other fertilizers or organic fertilizers and applied in the soil before cultivated. For topdressing: the topdressing should be applied in advance, which can be applied in furrow or mixed with water. Generally, 10-13 kg / mu of land is suitable, and 250-500 g / mu of fruit trees is suitable.
Potassium sulfite is used for foliar spraying: in order to correct the symptoms of crop magnesium deficiency, it can be used for root topdressing, but the effect of foliar spraying is not lasting, in order to achieve the effect, it should be sprayed several times continuously. Foliar spraying of potassium sulfite can be carried out in the early and middle stages of crop growth.
Agricultural potassium sulfite can also promote the formation of vitamin A and vitamin C in crops, so as to improve the quality of fruits and vegetables. At the same time, it can also promote the absorption of silicon and phosphorus by crops. After sufficient application of magnesium fertilizer, it can be applied at intervals of several crops instead of every season.
