Ten functions of silicon on plants

As a new type of inorganic mineral fertilizer, silicon element is a good quality fertilizer, health fertilizer and plant regulating fertilizer. It is a new type of multifunctional fertilizer that cannot be compared with other chemical fertilizers. It can be used as a fertilizer to provide nutrients and as a soil conditioner to improve the soil. Let's understand the role of silicon fertilizer on crop growth.

The role of silicon fertilizer

1. It is a kind of health-care nutrient element fertilizer: applying silicon fertilizer can improve soil, correct soil acidity, increase soil base, promote organic fertilizer decomposition, and inhibit soil bacteria. For example, the dry land of red soil has an acid pH value of about 4.5 to 5.2, lacks organic matter and calcium, and is easy to harden. Applying silicon fertilizer can improve soil properties, accelerate ripening, and increase crop production. Vegetable greenhouses have been planted continuously for more than two years, and the accumulation of mold and germs will affect the yield and quality of crops. Applying silicon fertilizer can effectively prevent the survival and reproduction of mold and root and stem rot and other crops.

2. It is an essential nutrient element for building plants: most plants contain silicon. Especially rice, its nutrient function is considered to be second only to N, P, K in recent years and ranks fourth. Tests show that when 1,000 kg of rice is produced, the amount of silicon dioxide absorbed is as high as 150 kg, which exceeds the sum of hydrogen, phosphorus, and potassium absorbed by rice. In the ash content of the six crops of rice, wheat, barley, soybean, lentil, and fennel, the oxides of seven nutritional elements such as silicon, phosphorus, potassium, and calcium accounted for more than 80% of the ash, of which silicon oxides accounted for 16-61.4%.

3. It is a nutrient element fertilizer that improves quality: applying silicon fertilizer to fruit trees can significantly improve fruit quality and increase fruit size. Increased sugar content. Sweet, fragrant and beneficial to human health. Also resistant to storage and transportation. Applying silicon to sugarcane can increase the yield, and in the later stage, it can promote the accumulation of sugar in the stem and increase the sugar yield.

4. It is a compound fertilizer with multiple calcium and magnesium elements: silicon fertilizer contains a certain amount of trace elements such as phosphorus, zinc, boron, iron, manganese, etc., and has a compound nutritional effect on crops. Suitable for a variety of crop applications.

5. It can help crops improve photosynthesis: silicon fertilizer can make the epidermis cells of crops silicified, make the stems and leaves of crops straight, reduce shading, and enhance photosynthesis of leaves. For example, after applying silicon to rice, the angle of the leaves is reduced, and the photosynthesis of the canopy is increased by more than 10%.

6. It can enhance the ability of crops to resist diseases and insect pests: after the crop absorbs silicon, silicified cells are formed in the body, the cell wall of the stem and leaf surface is thickened, and the cuticle is increased, thereby improving the ability of insect resistance and disease resistance, especially resistance to rice blast, leaf spot, and stem rot disease, bacterial blight, bacterial field disease, cotton bollworm, rust, etc.

7. It can improve the lodging resistance of crops: Because the stalks of crops are straight, the lodging resistance ability of crops can be increased by about 80%.

8. It can enhance the air permeability of crops: the amount of silicon in the crops increases, the rigidity of the crop tubes is strengthened, and the air permeability is enhanced. It is of great significance to aquatic and warm crops such as rice and reeds. It can also promote root growth and prevent root damage. decay and premature aging. In particular, it plays an important role in the control of rice root rot.

9. It can improve the stress resistance of crops: crops absorb silicon fertilizer to produce silicified cells, which can effectively regulate the opening and closing of leaf stomata and control water transpiration. Improve the ability of drought resistance, dry hot wind resistance and low temperature damage resistance. Silicon fertilizer is suitable for early spring crops. Such as early rice, early peanut and winter and spring vegetable production.

10. It can reduce the fixation of phosphorus in the soil: after applying silicon to the cultivated soil, it can activate the phosphorus in the soil and insoluble phosphorus, and promote the operation in the crop body, thereby increasing the seed setting rate.

Silicon fertilizer is listed as the fourth largest element fertilizer after nitrogen, phosphorus and potassium by the international soil community.
