Peppers are solanaceous vegetables that require more calcium. Pepper plant calcium deficiency, it is very easy to occur umbilical rot, resulting in rot of the umbilical pepper fruit, but also make the pepper color is not bright, especially in the winter planting pepper, pepper fruit is difficult to turn red.
Many pepper growers believe that since the umbilical rot of pepper is caused by calcium deficiency, foliar spray of calcium fertilizer can effectively prevent and cure the umbilical rot, but after repeated spraying of calcium fertilizer, there is still no obvious control effect, and umbilical rot occurs. Still very serious.
What causes the calcium effect to be poor? It turned out that this is because calcium has poor mobility in the soil, and the ability of pepper to absorb calcium is also very weak. Only relying on foliar spray of calcium fertilizer can not meet the needs of the plant, and the plant still lacks calcium. In order to ensure that the pepper plants have sufficient calcium supply, it is necessary to use calcium in the roots and calcium spray in the leaves, and the calcium in the roots should be the main supplement, supplemented with calcium in the leaves. The specific approach is as follows:
When growing pepper, the base fertilizer should be filled with calcium fertilizer, generally 80-100 kg of superphosphate or calcium magnesium phosphate per acre, or 15-20 kg of calcium nitrate or calcium ammonium nitrate per acre to meet the plant growth and development process. The basic requirements for calcium. During soil preparation, superphosphate or calcium magnesium phosphate fertilizer is evenly spread on the ground, and the ploughshare is ploughed to make the fertilizer and the soil fully and evenly contacted. Or when planting pepper seedlings, put calcium nitrate or calcium ammonium nitrate on the bottom of the planting hole, cover a small amount of soil before planting, or cover a small amount of soil after planting the pepper seedlings, then spread them around the pepper seedlings, and then cover the soil.
In addition, after the pepper seedlings are planted and lived, they must also be applied with an aqueous solution of 800-1000 times ammonium calcium nitrate once every 10-15 days, and continuously applied for 3 to 5 times. Each application of 0.5 to 1 kg of fertilizer solution per plant, evenly applied in the soil around the roots of pepper plants, with fertilizer solution completely infiltrated into the soil is not appropriate to flow.
During the flowering of peppers, the leaves should be sprayed once every 7 to 10 days with a 800-fold aqueous solution of Starch Calcium Magnesium No. 1 or a 1000-fold chelated calcium aqueous solution, or a 1000-fold aqueous calcium alkoxide solution, or a 1,000-fold aqueous polymerized calcium solution. Or 1000 times fluid calcium aqueous solution, or 800 times amino acid calcium aqueous solution, continuous spraying 3 ~ 5 times.
Evenly spray all the leaves, buds, and peppers to start dropping drops of water, supplementing calcium from the leaves. In this way, the combination of calcium in the roots and calcium in the leaves will have a good effect on calcium supplementation. The pepper plants will not be deficient in calcium, and the incidence of umbilical rot will be reduced, and the pepper fruits will be normally colored.
