In agricultural production, many farmers only pay attention to the application of nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, but the yield and quality of crops do not increase but decrease, which is due to the single nutrient of chemical fertilizers, and the partial application of one of the chemical fertilizers can easily lead to crop nutrient imbalance.
Today I will share with you a new fertilization method, that is, to increase the application of "silicon fertilizer". Silicon fertilizer is listed by the international soil community as the fourth major element fertilizer after nitrogen, phosphorus and potassium, in foreign countries, silicon fertilizer in rice yield increase effect has exceeded phosphate fertilizer and potassium fertilizer, while the mainland silicon deficiency soil up to 60% to 80%, increase the application of silicon fertilizer significantly.
Silicon fertilizer can not only provide nutrients, but also improve the soil, in addition to silicon fertilizer also has the role of disease prevention, insect control, is the development of green ecological agriculture of efficient and high-quality fertilizer, which has become a new type of fertilizer in the 21st century mainland.
What is the specific role of silicon fertilizer on the growth of crops?
First, silicon fertilizer is a plant regulatory fertilizer. There is antagonism between different chemical fertilizers, such as partial nitrogen fertilizer will inhibit the absorption of potassium by plants, and silicon can regulate the balanced absorption of different nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, etc., which can reduce the fixation of nutrients by the soil, and increase the application of silicon fertilizer can effectively prevent the symptoms of "lack of hormones" in plants.
Second, silicon fertilizer is a "quality" fertilizer. After the application of silicon fertilizer to the crop, the quality of the crop will be significantly improved, silicon fertilizer can prevent the occurrence of cracked fruit, deformed fruit, can enhance the shelf life of the fruit, in addition to calcium fertilizer can also improve the taste of the crop, so that the fruit shape is correct, good coloring, can greatly enhance the commerciality of the crop.
Third, silicon fertilizer can significantly enhance the lodging resistance of crops. Once the crops are lodging during the filling and milk maturation stages, they will seriously reduce yield and quality. Silicon fertilizer can increase the mechanical strength of crop stems, and the ability to resist lodging can be increased by more than 80%.
Like some crops that are prone to lodging, such as corn, wheat, rice, and sorghum, the application of silicon fertilizer can greatly improve the lodging resistance and is conducive to dense planting.
Fourth, silicon fertilizer can improve the resistance of crops to diseases and insect pests. After adding silicon fertilizer to crops, the cell walls of crop stems and leaves will be thickened, the stratum corneum on its surface will increase, and the protective layer formed will effectively increase the resistance of crops to diseases and insect pests.
The same land is divided into two halves, half of the soil is increased by silicon fertilizer, half of the soil is not applied with silicon fertilizer, and the ability of crops with more silicon fertilizer to resist whitefly, aphids, borers, root nematodes, rust, sclerotia, gray mold, green blight and other diseases and insect pests is significantly stronger.
Fifth, silicon fertilizer can enhance the stress resistance of crops. Climate has a very great impact on the growth of crops, so farmers are looking forward to "smooth wind and rain", and silicon fertilizer can enhance the drought resistance, dry and hot wind, cold resistance and other stress resistance of crops, and the adaptability of crops to climate changes will be strengthened.
Sixth, silicon fertilizer can improve the rate of photosynthesis. After the application of silicon fertilizer to crops, the content of chlorophyll in plant leaves will be significantly improved, the higher the chlorophyll content, the stronger the photosynthesis, and the stronger the photosynthesis, the more organic matter synthesized, the higher the yield and quality of the crop.
Seventh, silicon fertilizer can improve the soil. Long-term application of chemical fertilizers or heavy stubble cultivation is easy to lead to soil acidification, and silicon fertilizer can activate the beneficial microorganisms in the soil, can improve the soil, can balance the soil pH, and can create a soil environment suitable for crop growth.
How to apply silicon fertilizer when growing crops?
Silicon fertilizer We can choose "water-soluble silicon fertilizer", which can be used as a base fertilizer or as a foliar spray.
As a base fertilizer, we can mix and apply with ordinary chemical fertilizers, the amount per mu is 2 kg; if it is used for foliar spraying, we can dilute 1000 times and then apply, that is, spray 50 grams of water-soluble silicon fertilizer per mu with 50 kg of water, spray once every 10 days, spray 2 to 3 times continuously, silicon fertilizer can be applied in any growth period of the crop, without any side effects.
Mixed spraying of silicon fertilizer and foliar fertilizer can play the effect of "1+1>2"
First, silicon fertilizer + urea
For nitrogen-loving crops such as corn and leafy vegetables, we can spray "silicon fertilizer + urea", which can not only reduce pests and diseases, but also increase yields.
How to use: Per acre we can use 200 grams of urea + 50 grams of water-soluble silicon fertilizer, mix with 50 kg of water, fully mix well and then carry out foliar spraying, spray once every 10 days, spray 2 to 3 times continuously.
Second, silicon fertilizer + potassium dihydrogen phosphate
For solanum fruit vegetables (peppers, eggplants, tomatoes), root vegetables (potatoes, sweet potatoes, taro), fruits and other potassium-loving crops, we can spray "silicon fertilizer + potassium dihydrogen phosphate", which can not only make the fruit shape, good coloring, good taste, but also significantly increase the yield.
How to use: Per acre we can use 150 grams of potassium dihydrogen phosphate + 50 grams of water-soluble silicon fertilizer, mixed with 50 kg of water, mixed and sprayed, sprayed every 7 to 10 days, sprayed continuously 2 to 3. The best time for spraying is during the expansion and coloring periods of the fruit.
Note: Control the concentration when spraying to avoid fertilizer damage. In order to improve fertilizer efficiency, the best time to spray should be in the morning or evening when the evaporation is small, and the spray is prohibited when the sun is strong at noon.
In summary, silicon fertilizer is a good quality fertilizer, plant regulating fertilizer, known as "universal fertilizer". Silicon fertilizer can not only improve the soil, reduce the occurrence of pests and diseases, but also improve the yield and quality of crops, the use of silicon fertilizer for sustainable development of agriculture is of great significance.
