Pepper is an eggplant vegetable that requires more calcium. Pepper plants are deficient in calcium, which can easily cause umbilical rot, which causes the umbilical rot of pepper and fruit, and also makes the color of pepper and fruit not bright. Especially for peppers grown in winter, it is difficult to turn red.
Many pepper growers believe that since pepper umbilical rot is caused by calcium deficiency, foliar application of calcium fertilizer can effectively prevent umbilical rot, but after repeated spraying of calcium fertilizer, there is still no obvious control effect, and umbilical rot occurs. Still serious.
What causes the calcium effect to be bad? It turns out that this is because the calcium has poor mobility in the soil, and the ability of chilli leaves to absorb calcium is very weak. Spraying calcium fertilizer on the leaves alone cannot meet the needs of the plants, and the plants still lack calcium. In order to ensure that the pepper plants have sufficient calcium supply, a combination of calcium application at the root and foliar spraying of calcium must be used, and calcium supplementation at the root must be supplemented by calcium supplementation at the leaf surface. The specific method is as follows:
When planting peppers, sufficient calcium fertilizer should be applied to the base fertilizer. Generally, 80 to 100 kg of superphosphate or calcium magnesium phosphate fertilizer per acre, or 15 to 20 kg of calcium nitrate or calcium ammonium nitrate per acre can be used to meet the plant growth and development process. Basic requirements for calcium. During the preparation of the land, the superphosphate or calcium magnesium phosphate fertilizer was evenly spread on the ground, and then the plough was raked to make the fertilizer fully contact the soil evenly. Or when planting pepper seedlings, place calcium nitrate or calcium ammonium nitrate at the bottom of the planting hole and cover with a small amount of soil before planting, or cover a small amount of soil after planting the pepper seedlings, and then spread it around the pepper seedlings, and then cover the soil.
In addition, after the pepper seedlings are planted to survive, the roots must also be sprayed with an aqueous solution of calcium ammonium nitrate 800 to 1000 times every 10 to 15 days, and continuously sprayed 3 to 5 times. Apply 0.5 to 1 kg of fertilizer solution per plant every time, and evenly apply it to the soil around the roots of pepper plants. It is advisable that the fertilizer solution completely penetrates into the soil and does not flow out.
During the flowering and pepper seasoning of pepper, foliar spray of 800 times the aqueous solution of Xing Peng Calcium Magnesium No. 1 or 1000 times the aqueous solution of chelated calcium, 1000 times the aqueous solution of calcium sugar alcohol, or 1000 times the aqueous solution of polymerized calcium is required every 7 to 10 days. Or 1000 times fluid calcium aqueous solution, or 800 times amino acid calcium aqueous solution, continuous spraying 3 to 5 times.
Spray all the leaves, flower buds, peppers and fruits evenly. It is advisable to start to drip water drops and add calcium fertilizer from the leaves. In this way, the combination of calcium supplementation at the root and calcium supplementation at the leaf surface can have a good calcium supplementation effect, the pepper plant will not be deficient in calcium, the occurrence of umbilical rot will be reduced, and the pepper fruit will be colored normally.
