In recent years, umbilical rot caused by calcium deficiency has jeopardized vegetables, so many vegetable farmers have increased the amount of calcium fertilizer applied. Coupled with many dealers have repeatedly misled the vegetable farmers: calcium fertilizer must be applied when the application of base fertilizer. This makes the vegetable farmers think that a large amount of calcium fertilizer should be applied when applying the base fertilizer.
In fact, not the more calcium fertilizer is applied, the vegetables will not be deficient in calcium. Although calcium fertilizer has poor mobility in soil and in plants, it is mainly based on base application. However, a large number of vegetables exhibit calcium deficiency symptoms but not due to insufficient application of calcium fertilizer. However, in recent years, the application of chemical fertilizers has led to the concentration of salt ions in soil. Too high, affecting the absorption of calcium by vegetables. Therefore, the key to the problem is to allow the vegetables to fully absorb the applied calcium fertilizer, rather than simply increasing the amount of calcium fertilizer applied. Moreover, excessive application of calcium fertilizer will also change the acidity and alkalinity of the soil, which is very unfavorable for vegetable growth. Generally, 50 kg of calcium fertilizer can be applied per acre. At the peak of the vegetable season, the amount of calcium needed for the plant will increase greatly. At this time, calcium should be supplemented by spraying the calcium-containing foliar fertilizer.
