Foliage topdressing is a fertilization method often used in production. Fertilizers suitable for topdressing of peanuts and their application methods are:
1. Urea in the middle and late stages of peanut growth, if the plants have defertilizer phenomenon, or continuous rainfall during the growing period of peanuts caused water accumulation in the field, the roots are difficult to attract fertilizer, can be sprayed with 1% urea solution, spraying 60 kg per acre. .
2.Superphosphate peanut leaves have a strong absorption capacity for phosphorus. In the middle and late stages of growth, they are sprayed with 2-3% of superphosphate calcium leachate once every 7-10 days, and sprayed 2-3 times per acre. Sub-spraying about 60 kilograms can speed up the speed of photosynthetic products to pods, generally increasing production by 7-10%.
3. Urea and superphosphate mixed spray in phosphorus deficiency and nitrogen deficiency land, can be added in 100 kg of 2% superphosphate leachate 1 kg urea mixed spray, both labor, the effect is good.
4. Potassium Dihydrogen Phosphate Potassium Dihydrogen Phosphate is a dual compound fertilizer of phosphorus and potassium. Spraying on the upper leaf of peanut can increase production by 18.2-26.9%. Application method: Use 150-200 grams of potassium dihydrogen phosphate per acre, 50 kg of water, and spray it in the evening or cloudy afternoon after it is fully dissolved. It is best to spray 3 times, each time for 7 days; if after spraying, 8 Rain within hours, re-spray once.
5. Potassium fertilizer is sprayed with 5-10% ash leaching solution or 2% potassium sulphate (or potassium chloride) solution, spraying 60 kg per acre.
6. For each ton of dry matter formed by iron-fat peanuts, 264 grams of iron need to be absorbed, and iron fertilizers should be applied to iron-deficient soils, generally increasing production by more than 10%. Method of application: In the peanut flowering stage, crusting stage, or when the iron deficiency symptoms appear in plants, spray once every 5-6 days with 0.2% ferrous sulfate solution and spray 2-3 times continuously.
7. Boron peanuts need to absorb 44 grams of boron for each ton of dry matter formed, and apply boron fertilizer for boron-deficient soil, generally increasing production by 7.8-22.5%. Application method: In peanut seedling stage, initial flowering stage and flowering stage, spraying with 0.2% borax or boric acid solution.
8. Manganese Peanuts Each ton of dry matter formed requires the absorption of 39 grams of manganese. Manganese fertilizer is applied to soils lacking manganese, which generally increases production by 8-11%. Application method: Start from 30-50 days after sowing of peanuts and 15-20 days before harvest, spray once every 10-14 days with 0.1% manganese sulfate solution; if necessary, with the fungicide to control peanut leaf spot Mixed application.
9. Molybdenum peanuts Each ton of dry matter formed requires the absorption of 1.32 grams of molybdenum, and the application of molybdenum fertilizer in the absence of molybdenum can increase production by 11.39%. Application method: In the peanut seedling stage and flowering period, spraying with 0.1-0.2% ammonium molybdate solution.
10. Rare earth micro-fertilizer Rare earth micro-fertilizer is also called rare earth nitrate. It is a new type of rare earth element fertilizer that was first introduced and promoted in China. Applying on peanuts generally increases production by 9.5-14.1%. Application method: 40 grams of rare earth micro-fertilizer per acre, 50 kilograms of water, foliar spraying at the beginning of flowering period.
