1, base fertilizer in Pu Shi decomposed organic fertilizer, phosphorus, potassium fertilizer, sandy soil should increase calcium magnesium phosphate fertilizer, calcium superphosphate, calcium nitrate and other calcium-containing fertilizer; old vegetable gardens and heavy land should increase lime, each year Mu application of calcium fertilizer is 1.67 ~ 3.33 kg.
2, foliar fertilizer per 100 kg of water plus 1 ~ 2 kg of superphosphate, stirring for half an hour, then soak for a period of time, the above supernatant can be sprayed, can also choose amino acid calcium, calcium humate, biological calcium fertilizer Etc., sprayed during the peak period of calcium absorption in vegetables.
3, scientific application of nitrogen and potassium fertilizer ammonium ions and potassium ions and calcium ions between the antagonistic effect, the soil ammonium, potassium content is too high, and nitrogen and calcium ratio is too high, can inhibit the absorption of calcium. The use of nitrogen and potassium fertilizers should be properly controlled and scientific fertilization should be conducted to avoid the phenomenon of excessive nitrogen and potassium fertilizers.
4. Addition of Organic Fertilizer Organic fertilizer is rich in organic matter and various nutrients required by crops. It is a complete fertilizer and has a unique effect on improving soil and fertility.
5. Appropriate amount of boron for proper application of boron fertilizer can promote the transportation of carbohydrates from the leaves to roots, promote new roots, and facilitate the absorption of calcium. In the case of calcium supplementation on the soil and foliar spray, appropriate amount of borax can be incorporated. .
