Calcium is an essential nutrient for the growth of vegetables. However, some vegetable farmers have recently reflected such a situation. They have already supplemented calcium, but the vegetables in vegetable greenhouses are still lacking calcium. Problems caused, such as cracking caused by calcium deficiency, slowness, low yield, etc. What is this situation? Let Xiaobian give you an analysis of the reasons: 1. Soil acidification: If the greenhouse soil is planted continuously for many years, fertilization and long-term imbalance will cause soil acidification and compaction, which will not only affect the soil calcium content, but also cause the roots to absorb nutrients. 2, root injury or temperature discomfort: Because the absorption of calcium mainly depends on transpiration, so the factors affecting transpiration can affect the absorption of calcium. If the soil is dry, improper watering or improper fertilization, the root system is damaged, resulting in calcium deficiency in the plant. 3. Unreasonable fertilization: If the high-potassium fertilizer is continuously applied to the vegetable soil, the fertilization will be unbalanced, and the calcium deficiency will occur in the vegetables for a long time. If calcium has been supplemented, but vegetables are still deficient in calcium, I think it is mainly due to the quality of calcium fertilizer or improper use. The key to calcium supplementation depends on absorption. Calcium deficiency prevention measures: 1. Strengthen comprehensive management: As the temperature decreases, it is necessary to properly regulate the temperature and do a good job of shed insulation. Secondly, we must ensure that the water is evenly supplied. It should not be too dry or too wet, otherwise it will affect the growth of roots and the absorption of calcium. 2. Combination of spraying and flushing, and rational supplementation of calcium fertilizer: The supplement of calcium fertilizer must be early, after the vegetable is planted, the seedling period, growth period and fruit setting period should be supplemented. 3. Foliar application of calcium fertilizer: When the root system is damaged or unsuitable for watering, calcium fertilizer can be added through the foliar surface, and the young part is sprayed with emphasis. After understanding the causes and prevention measures of calcium deficiency in vegetables, you can go back and look at your own vegetables. Is there any such situation? If there is, then you have to do it quickly. Urostomy Bag,Ileal Conduit Bag,Urostomy Bag Covers,Urine Ostomy Bag Wenzhou Celecare Medical Instruments Co.,Ltd , https://www.wzcelecare.com
