Some vegetables produce vegetable umbilical rot, and most of the vegetable umbilical rot is caused by calcium deficiency. So, how should vegetable umbilical rot be controlled?
Therefore, many vegetable farmers will apply calcium fertilizer to vegetables, which is actually very skillful.
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.
Metal silicon, also known as Crystalline Silicon or Industrial Silicon, is mainly used as an additive to non-ferrous based alloys. Metal silicon is a product made of quartz and coke in an electric furnace. The content of silicon in the main component is about 98% (in recent years, 99.99% of Si is also contained in metal silicon), and the remaining impurities are iron and aluminum. , calcium, etc.
