The symptoms of potassium deficiency in peanuts are characterized by thick green leaves. The yellow leaves appear at the edge or tip of the leaflets from the old leaves. The leaves are even brown when the potassium is severely deficient. The uneven growth of the leaves often causes curling or ripples, which affects photosynthesis. Working with matter. Therefore, in the soil of potassium deficiency, special attention should be paid to the application of potassium fertilizer. Even in soils with high potassium content, proper potassium application can increase the yield and quality of peanuts.
Potassium application of peanuts should be carried out in stages, especially in the soil of potassium-deficient soil, and the effect of potassium application is more significant. The plant ash and soil fertilizers are rich in potassium. About 75 kilograms of wood ash per acre is used as the base fertilizer, and 5-7 kilograms of potassium sulfate can also be used. Potash, such as grass ash, is easily lost and should be applied in deep layers. Peanut flowering period requires a large amount of potassium. In the early flowering stage, 50-75 kg of grass ash is applied to the acreage, which has a certain yield increase effect. In order to improve the effect of potassium application, attention should be paid to the combination of nitrogen and phosphorus nutrition. When the nitrogen and phosphorus nutrition is sufficient, the potassium fertilizer at the flowering stage has a good effect.
