The main role of silicon fertilizer and scientific application method (1) The main effect of silicon fertilizer on crops Silicon fertilizer is more and more recognized by people. It is believed that silicon enters the plant body to help control transpiration, so that the leaves will not be excessively wilted under strong light and drought conditions, thereby increasing photosynthesis efficiency; at the same time, silicon can also promote surface cell siliceous It enhances the mechanical strength of crop stems, improves resistance to lodging and disease resistance. The average content of silicon in the soil is 32%, but the soluble effective silicon is low and it is difficult to be absorbed by crops. The more acidic the soil and the more sand the texture, the lower the effective silicon content. Some crops have large silicon absorption. For example, rice absorption of silicon is about twice the sum of absorption of nitrogen, phosphorus, and potassium. Silicon is more demanding, and silicon fertilizers can increase production in silicon-deficient rice fields. %about. (2) Application method of silicon fertilizer The silicon fertilizer is generally alkaline, and it can neutralize acidity when applied in acid soil, which can reduce the toxicity of aluminum ions and reduce the fixation of phosphorus, and improve the phosphorus nutrition condition of crops. At the same time, reasonable application of silicon and nitrogen fertilizer can increase the efficiency of silicon fertilizer. Silicon fertilizers are generally used as base fertilizers. The effective silicon content in the soil with silicon fertilizer is less than 90mg/kg, the application amount is 20kg/mu, and silicon-calcium fertilizer and silicon-manganese fertilizer are applied in 100kg/mu.
