Silicon fertilizer has been widely promoted and used in developed countries and regions such as South Korea, the United States, France, Malaysia and Taiwan. It is reported that the effect of silicon fertilizer on rice production has exceeded that of phosphate fertilizer and potassium fertilizer. At the same time, silicon fertilizer can improve the quality of products, such as apple sugar content, coloring rate, storability and transportability. Silicon fertilizer can also play a role in disease prevention and pest control, such as rice blast, leaf spot, bacterial blight, stem rot and so on.
Application effect of silicon fertilizer on various crops (for reference)
- Rice -
The effect of increasing production is particularly obvious. The rice epidermal cells can be thickened, the stems and leaves of the crops are thick and straight, the roots are developed, the photosynthesis is enhanced, the effective tillering, the seed setting rate is high, the ear and large grains are more, the drought resistance and lodging resistance are improved by more than 85%, the early maturity is promoted, and the rice quality is improved. , resistant to pests and diseases, can reduce the incidence rate by 75%;

After spraying silicon fertilizer, the strawberry fruit can be enlarged, the appearance is bright and round, shiny, the strawberry fruit rate is increased, the quality is good, the harvesting period is 7 days earlier, and the economic value is improved. The test shows that the aphid occurs after spraying the silicon fertilizer. The rate is reduced by 75%, and the resistance to gray mold is 40%-53%. It is also resistant to other diseases such as powdery mildew and viral diseases.
-Chinese cabbage -
After spraying the silicon fertilizer, the plant growth is robust, the incidence of dry heartburn and soft rot is reduced, and the aphids are also greatly reduced.
- Chili, eggplant, tomatoes -
After spraying silicon fertilizer, the plants are robust, the leaves are dark green, the fruit setting rate is high, the fruit shape is correct, the yield is high, and the pests and diseases are few.
-cucumber-
After spraying silicon fertilizer, the stems and leaves are straight, the photosynthesis is enhanced, the growth is good, the market is early, the color is good, the taste is good, the pests and diseases are few, powdery mildew, blight and leaf spot are basically absent, and the quality and yield are obviously improved.
-watermelon-
After spraying silicon fertilizer, it grows strong, thin skin, crisp and sweet meat, high sugar content, less pests and diseases, high yield and good quality.
-potato-
After spraying silicon fertilizer, the growth rate is strong, the incidence of powdery mildew is low, the size is large, the appearance is smooth and there is no dark spot, and the quality is improved.
-tobacco-

-lawn-
Spraying silicon fertilizer can significantly improve the mechanical strength of grass stems, and has a resistance to diseases caused by various fungi such as leaf spot, brown spot and blight of lawn.
-Chinese herbal medicines -
After spraying silicon fertilizer, the plant grows robustly, with less insects, less disease and good quality.
Ten advantages of silicon fertilizer:
1. Silicon is an important nutrient element of plant composition, and is listed as the fourth largest element after nitrogen, phosphorus and potassium by the international soil community;
2. Silicon fertilizer is beneficial to increase the photosynthesis and chlorophyll content of crops, make the stems and leaves straight, and promote the accumulation of organic matter;
3. Silicon fertilizer can increase the mechanical strength of crop stems and increase the lodging resistance by more than 85%, so that the stems are straight and conducive to close planting;
4. Silicon fertilizer can improve the resistance of crops to pests and diseases, reduce the occurrence of various diseases and insect pests. After the silicon is absorbed by the crops, silicified cells can be formed in the plants, the cell wall of the stems and leaves is thickened, and the stratum corneum is increased to form a strong protection. The layer makes the insects difficult to bite and the bacteria are difficult to invade. (especially for rice blast, sheath blight, bacterial blight, stem rot, rotten rot, leaf spot, smut, sclerotinia, rust, powdery mildew, black spot, downy mildew, ash Mildew, bacterial wilt, blight, root rot and aphids, rice planthoppers, aphids, cotton bollworm, borer, whitefly, root-worm and other pests and diseases;
5. Silicon fertilizer can enhance the air permeability of crops, prevent root rot and premature aging, and play an important role in the prevention and control of rice root rot disease.
6. Silicon fertilizer can effectively regulate leaf stomatal opening and closing and inhibit water transpiration, and enhance crop drought resistance, dry heat resistance, cold resistance and low temperature resistance;
7. Silicon fertilizer can enhance the pollen vigor of melon and fruit crops, and apply silicon fertilizer during flowering period, which can significantly improve the rate of achievement;
8. Silicon fertilizer can reduce the fixation of phosphate fertilizer in soil, activate phosphorus in soil and promote the absorption of phosphorus by roots, and improve the utilization rate of phosphate fertilizer. Strengthening the absorption and utilization of calcium and magnesium can regulate the balanced absorption of different nutrients such as nitrogen, phosphorus and potassium in crops, and is called “plant regulating fertilizerâ€;
9. Silicon fertilizer is a health fertilizer that can activate beneficial microorganisms, improve soil, correct soil acidity, improve soil salt base, promote decomposition of organic fertilizer, inhibit soil bacteria, resist heavy mites and reduce heavy metal pollution (such as continuous cultivation of plastic greenhouse for more than 3 years). It will encounter the accumulation of soil-borne pathogens such as mold, which will seriously affect the yield and quality of fruits and vegetables. The application of silicon fertilizer will effectively prevent the survival and reproduction of molds;
10. Silicon fertilizer is a quality fertilizer, which can significantly improve the quality of agricultural products, effectively prevent cracking, shrinkage and deformed fruit, increase the hardness of the fruit, make the fruit shape correct, good coloring, good taste, good commodity, resistant to storage and transportation, and extended preservation. period.

Silicon fertilizer, a medium-quantity element fertilizer, was first discovered in 1787 by Lavoisier in the presence of silicon. Introduced systematically by Cai Delong, and realized industrial production and agricultural applications.
According to the current Chinese fertilizer classification method (large amount of elements, medium amount elements, trace element fertilizers), the fertilizer and calcium fertilizer are medium-weight element fertilizers. Since 1996, the Henan Provincial Academy of Sciences has set up the “Henan Province Silicon Fertilizer Engineering Technology Research Centerâ€. The China National Silicon Fertilizer Standard is responsible for the formulation and implementation.
