The rare-earth microelement fertilizer used in agriculture uses rare earth chloride as a raw material to remove radioactive impurities, and its radiation dose is equivalent to that of nitrogen fertilizer, which is lower than that of phosphate fertilizer. Although rare earth elements are not essential nutrients for crop growth and development, it has been proved that it has the function of regulating cell membrane permeability of crops, can protect cell membranes, delay cell aging, and can regulate the water holding capacity of cells, thereby improving the drought resistance and cold resistance of crops. Strengthens the synthesis of nucleic acids and proteins in crop cells, induces the production of resistant proteins, promptly repairs intracellular mitochondria, renews chlorophyll, and increases the photosynthetic rate of crops. It can significantly promote the absorption, transformation, and operation of nitrogen in crop roots; The intensity of crop photosynthesis is conducive to more accumulation of carbon nutrients. Application on greenhouse vegetables can promote photosynthesis to enhance the resistance of plants to improve the ability of seedlings to withstand adverse environments such as low temperature, high temperature, and low light, thereby promoting high quality, early maturity and increased yield. Such as: tomato application of rare earth micro-fertilizer, can increase plant height, leaf speed, leaves increased, the flowering period 3-5 days in advance, the number of fruits per plant increased by 2-20, the Fruit sugar content increased by 10% -20%, Precocious 5-7 days. The use of rare earth micro-fertilizers on cucumbers can generally increase the previous production by more than 40% and increase the total production by 20%. In fruit trees, Rare Earth Micro Fertilizer can stimulate plant growth, promote rooting and root elongation of cuttings, and enhance root activity, so as to achieve the purpose of increasing fruit setting rate and increasing yield. For example, application of rare earth micro-fertilizer on grapes can improve grape quality, effectively reduce the size of grains, and increase the fruit setting rate, increase the vitamin content of fruits and optimize the acid-sweet ratio, and can also promote early maturing. Rare earth fertilizer is a new plant nutrient and regulator. However, it is not allowed to over-apply in greenhouse vegetables, and the application method should be scientific. The correct method of application is: 1. When used as a base fertilizer, strictly adhere to the recommended method and dosage of the book. 2. Seed dressing: first 1-2 grams of rare earth fertilizer dissolved in 1.5 kilograms of water, and then use a sprayer or a small watering can spray on the cucumber seeds, while spraying and mixing, dry sowing. 3. Foliar spraying: 10 grams of rare earth micro-fertilizer per acre greenhouse, dubbed into a concentration of 0.03% -0.06% solution, first sprayed in the initial flowering period, then spray again about 20 days. The specific spraying concentration depends on the active ingredient content of the product. Please refer to the product manual before use to avoid improper use of the crop.
