Peanut spraying foliar fertilizer points

March 10, 2023

(1) Apply 1 kg of nitrogenous fertilizer urea to foliar, 100 kg of clear water to dissolve 1% aqueous urea solution; if there is defertilization during the middle and late stages of peanut growth, or continuous rainfall during the growing period of peanuts, the water in the soil, and the nutrients in the root system is difficult to absorb, Sprayable, spraying 60kg urea aqueous solution per acre.
(b) Foliar application of phosphorus fertilizer Peanuts have strong absorption capacity for phosphorus. Spraying superphosphate solution in the middle and later stages of fertility can increase the yield of pods. 2-3kg superphosphate, 100kg water, stirring soaking, after a day and night, take the supernatant application, generally every 7-10 days spray once, and even spray 2-3 times, spray 60kg per acre. Be careful to remove the residue completely so as not to damage the blade.
(3) Nitrogen and phosphorus may be mixed in a peanut field that is deficient in phosphorus and lacks nitrogen. A mixture of 1% urea and 2% of superphosphate may be sprayed, which is a good method and the effect is good. Preparation method: 100 kg of 2% superphosphate Urea lkg is added to the calcium aqueous solution.
(4) The foliar application of potash fertilizer is generally formulated with plant ash. The preparation method is to take 5-10kg of ash without rain, add 100kg of water and stir well, immerse for 12-14 hours, take the clear solution, which is 5%-10% of the ash leaching solution, about 60kg per spraying. An aqueous solution of potassium sulfate or potassium chloride may also be used. The preparation method is to add potassium sulfate or potassium chloride 2 kg in 100 kg of clean water, and dissolving and stirring to prepare a 2% solution of potassium sulfate or potassium chloride, each spray 60 kg per acre. .
(5) Phosphorus and potassium combined to take 5kg of hay ash, add 40-50kg of water to soak, take 2g of calcium phosphate, and soak it in the soaking solution. Mix thoroughly and filter out the clear solution after a long time. Add water to the remaining solution to soak it for 20k. , And then combined two times the filtrate, the water to 100kg, that is, the method of production of potassium dihydrogen phosphate, spraying 60kg per acre, spraying two times that there is a significant increase in production.
(6) Problems of Attention
1. It is necessary to determine the fertilization time according to the growth condition and growth period of peanuts, and it should generally be applied at the later stage of fertility.
2. To choose no windy cloudy days, or spray on sunny days before 9:00 and after 4:00 pm to increase the amount of leaf absorption and prevent damage to the leaves. After 4 hours of spraying, rain should occur.
3. To strictly control the spraying concentration, the concentration of large and easy to damage the leaves, causing damage.
4. When spraying, spray evenly, spray the front and back of the leaf.
(b) Foliar application of phosphorus fertilizer Peanuts have strong absorption capacity for phosphorus. Spraying superphosphate solution in the middle and later stages of fertility can increase the yield of pods. 2-3kg superphosphate, 100kg water, stirring soaking, after a day and night, take the supernatant application, generally every 7-10 days spray once, and even spray 2-3 times, spray 60kg per acre.
