When it comes to silicon fertilizer, it is generally believed that rice is prone to lack of silicon, causing the leaves to be slack, with dead spots, poor erect erectility, easy lodging, premature aging, and greatly reduced yield, but little is known about its other effects on crops. In fact, silicon is the fourth element required for plants after NPK.
Silicon has a major impact on the yield and quality of crops. The mechanism of action is multifaceted: after application of silicon fertilizer, the epidermal cells can be silicified, the stems stand upright, and the photosynthesis of the leaves is enhanced. Silicified cells can also increase the thickness of the cell wall, forming a strong protection god, the disease is difficult to invade; pests and diseases are resisted once they are harmed. After the crop absorbs the silicon fertilizer, the rigidity of the catheter is strengthened, which prevents the lodging and promotes the growth of the root system, and is an important part of maintaining the normal life of the plant.
In addition, silicon has a "magic" effect. The lack of silicon can make the fruit and fruit deformed, the color is gray, the sugar content is reduced, the taste is deteriorated, and the commodity is affected. Adding silicon fertilizer can greatly improve these traits. For example, some markets offer "sweet" cucumbers that use silicon fertilizer. The apples in Sanmenxia, Henan Province are well-known both at home and abroad. They are not only good in commodity, but also resistant to storage and not easy to lose water. They use silicon fertilizer. The physiological explanation from the plant is that under the regulation of silicon fertilizer, plants can inhibit the excessive absorption of nitrogen fertilizer by crops, and correspondingly promote the conversion of assimilation products to polysaccharides. Therefore, it is necessary to ensure high yield in agriculture. High quality, this requires the application of silicon fertilizer. However, due to the stable nature of silicon, it will be fixed in the form of compounds in the soil, and the mobility is poor. Therefore, we must supplement it by applying silicon fertilizer, which is more necessary nowadays in the application of organic fertilizers.
After applying silicon fertilizer, it generally has a more obvious effect of increasing yield. According to the data, silicon fertilizer not only has obvious effects on the yield increase of undergraduate crops, but also has good yield-increasing effects on white, tomato, cucumber, watermelon, pumpkin, green pepper and other vegetables. The yield increase can reach 22.6%-63.1%.
