The method of spraying foliar fertilizers out of the roots to supplement nutrients to allow direct absorption and utilization of rice stems and leaves, less fertilizer, and quick results is a common measure for high-yield cultivation of rice. The types and application methods of rice leaf foliar fertilizers are as follows: 1. Nitrogen fertilizer spraying nitrogen fertilizer in the middle and later stages of rice breeding can prolong the life of functional leaves and prevent premature denitrification. The 1% urea solution is sprayed once during the booting stage and at the beginning of the grouting period, and the spraying effect is better if it is mixed with 3000-4000 times the 920 regulator. 2. Phosphate Fertilizer Spraying phosphorus at late growth stage of rice can increase seed setting rate and 1000-grain weight and promote early maturing. Two times of 2% calcium superphosphate solution is sprayed from the heading to the grain filling stage. In the nitrogen-depleted field block, a proper amount of urea mixed spray can be added to the prepared phosphate fertilizer solution. 3. Potassium fertilizers were sprayed once during the booting and heading stages of potash rice, which promoted heading and increased the seed setting rate. Take 5 kg of fresh grass ash, add 100 kg of fresh water, stir and soak for 12-24 hours, then take the supernatant and spray it with 50 kg of spray fertilizer. Can also be sprayed with 1% potassium chloride solution. 4. Potassium dihydrogen phosphate rice spraying potassium dihydrogen phosphate, can improve the resistance, enhance heat resistance and cold resistance, increase grain weight gain, and increase production. At the booting stage, heading stage, and filling stage, spray 1 time, and use 150 g of potassium dihydrogen phosphate per mu, and add 50 kg of water to spray. When heading reaches 20%, the use of potassium dihydrogen phosphate 150 grams plus 1-2 grams of 920, plus 50 kg of water diluted evenly sprayed, can promote the earing and tidy, reduce the neck package, increase production significantly. 5. Zinc fertilizer rice is sensitive to zinc. Spraying zinc fertilizer once at the heading stage and heading stage can promote the ordering of heading, enhance the function of leaves, accelerate the nutrient operation, and be conducive to grouting. Each time, 100 grams of zinc sulphate is used, and 50 kg of water is diluted and sprayed. The effect of mixing with potassium dihydrogen phosphate is better, but it should not be mixed with phosphorus fertilizer. 6. The supply of boron nutrient was sufficient at the grain filling stage of boron fertilizer, and the seed setting rate was high and the empty crop was small. Especially the hybrid rice had more obvious effect of increasing the yield. The 0.1%-0.2% borax solution was sprayed once at full heading stage and filling stage to increase production by about 10%. When the rice is in low temperature and rainy conditions during grain filling, spraying boron fertilizer is better. Spray borax, should be dissolved with a small amount of warm water, then diluted with water to the required concentration and sprayed.
Standardized Herbal Extract
A standardized herbal extract is an herb extract that has one or more components present in a specific, guaranteed amount, usually expressed as a percentage. The intention behind the standardization of herbs is to guarantee that the consumer is getting a product in which the chemistry is consistent from batch to batch. This practice has developed out of the drug model of herbal medicine, in which modern scientists have attempted to identify the components of a plant that have definite pharmacological activity in the body. Unfortunately, while scientists can isolate many constituents from an herb and discover how particular chemicals may act in the body, they inadvertently remove or overlook components that may contribute to the activity of the whole herb. Consequently, standardization may concentrate one constituent at the expense of other potentially important ones, while changing the natural balance of the herb`s components.
