Appropriate application of lime and phosphate fertilizer is good as calcium, magnesium and phosphate fertilizer, the amount is generally 15 to 20 kilograms per mu, potash potassium chloride or potassium sulfate is preferred, dosage is 10 kilograms per mu. When sowing in acid red soil, 20-30 kilograms of lime per acre is applied to neutralize acidity; when fertilizing soil, a lime of 30-40 kg per acre is applied.
Adding gypsum red soil acidic soil is generally acidic, gypsum top dressing than basal fertilizer application effect is good, flowering period in the strong circle of 20 to 35 kg gypsum powder per acre effect is best.
When molybdenum dressing is sown, 2 grams of ammonium molybdate per kilogram of peanut is mixed. First, dissolve the ammonium molybdate with a small amount of hot water, then dilute it with cold water to a concentration of 1%, and mix it for 3 to 4 hours before planting. In the lack of molybdenum soil preparation, 50 to 100 grams of ammonium molybdate can be applied per acre.

After applying a large number of fruit needles into the soil at the flowering stage, the foliar dressings should be promoted and controlled in combination with foliar spraying. The spraying concentration is preferably 200-300 micrograms per liter of solution containing trichlorobenzoic acid. During the flowering period of peanuts, a 0.4% aqueous solution of potassium dihydrogen phosphate was sprayed once every 7 days and sprayed three times.
