Peppers planted in winter are prone to rot, cracked pepper, and poor coloration. The main cause is calcium deficiency in plants. Because of the low temperature in winter, the large temperature difference between day and night, and the dry climate, which affects the absorption of calcium in pepper roots and the transportation of calcium in pepper plants, it is easy to cause calcium deficiency. Therefore, during the winter season, peppers must be supplemented with calcium fertilizer during flowering and peppering. To ensure the supply of calcium. Specific supplementary methods: During the blooming of chili peppers, the roots must be applied once every 15 to 20 days and 200 to 300 times calcium ammonium nitrate aqueous solution, or 600 to 800 times calcium and magnesium magnesium sulfate aqueous solution, continuously applied for 2 to 3 times. Each application of 1.5-2 kilograms of planting should be applied evenly to the soil around the roots of the pepper plants. It is advisable that the fertilizer solution completely infiltrate into the soil without flowing out. At the same time, the leaves were sprayed with 800-fold chelated calcium aqueous solution or 1000-fold activated calcium aqueous solution, or 800-fold fluid calcium aqueous solution, or 1000-fold aqueous calcium alkoxide solution, or 800-fold aqueous polymerized calcium solution, or 600-fold amino acid, every 7-10 days. Calcium aqueous solution, or 500 times calcium nitrate aqueous solution, etc., is continuously sprayed 3 to 5 times. Spray all the leaves, buds, and peppers evenly to start dropping drops of water. In this way, supplementing calcium fertilizer from leaf surface has obvious effects on promoting enlargement, ripening, coloration, crack prevention, and control of rot in the umbilicus, as well as improving the storage stability.
