How do peanuts spray foliar fertilizer?

How do peanuts spray foliar fertilizer? Please introduce that foliar fertilizer spraying on peanuts has the effects of high fertilizer absorption and utilization, saving fertilizer, increasing production and so on. With the application of nitrogen fertilizer on the leaf, the absorption and utilization rate of peanut plant reached more than 55.5%, the number of full fruits increased significantly, and the economic benefit increased significantly; when phosphate fertilizer was applied on the leaf, it could increase yield by 7%; and micro-fertilizer, such as molybdenum, boron, manganese, iron, etc., could increase the yield by 8%. 1 kg of urea is obtained by spraying nitrogen fertilizer, and 100 kg of clear water is fully stirred to dissolve 1% urea aqueous solution. If there is the phenomenon of de-fertilization in the middle and later stage of peanut growth, or when it is difficult to absorb nutrients by continuous rainfall, stagnant soil and root system, it can be sprayed with 60 kg urea solution per mu. Spraying phosphate fertilizer on peanuts has a strong ability to absorb phosphorus. Spraying 2% Mel 3% calcium superphosphate aqueous solution on the leaves in the middle and later stages of growth can increase the rate of photosynthate transporting to pods and increase pod yield. The specific method is as follows: put 3 kilograms of calcium superphosphate in 100 kilograms of water, stir and soak, after one day and night, take the upper clarifying liquid to apply, generally spray every 10 days, spray 3 times, each time about 60 kilograms per mu. Care should be taken to remove the residue thoroughly so as not to damage the leaves. Mixed spraying of nitrogen and phosphorus in peanut fields deficient in phosphorus and nitrogen can spray a mixture of 1% urea and 2% superphosphate. The preparation method of the mixture is as follows: 1 kg urea is added to 100 kg 2% superphosphate aqueous solution. Spraying potash fertilizer is generally prepared with plant ash. The preparation method is to take 10 kg of undrenched plant ash, add 100 kg of water, fully stir, soak 12ml for 14 hours, and take the clarification solution, that is, 5%-10% of the plant ash leaching solution, spraying about 60 kg per mu. Potassium sulfate or potassium chloride aqueous solution can also be used, spraying 60 kg per mu. Use phosphorus and potassium to take 5 kg of dry plant ash, add water 40Mel 50 kg to soak, at the same time take 2 kg of calcium superphosphate, sprinkle it into the soaking solution, fully stir well, filter out the clear solution half a day later, add 20 kg of water, soak and filter, and then combine the filtrate twice and mix it with water to 100 kg, that is, the potassium dihydrogen phosphate solution prepared by local method, each time spraying 60 kg per mu. The problems that should be paid attention to in foliar spraying of peanut are as follows: 1. The fertilization time should be determined according to the growth situation and growth period of peanut, which is generally applied in the later growth stage. 2. Spray on windless and cloudy days or sunny days before 9: 00 a.m. and 4: 00 p.m., in order to increase leaf absorption, prevent damage to leaves, and make up spraying 4 hours after spraying in case of rain. 3. It is necessary to strictly control the spraying concentration, which is easy to damage the leaves and cause fertilizer damage. 4. Spray evenly and carefully when spraying, and spray both sides of the leaves.
