Fertilizers are quick-acting nitrogen and phosphorus mixtures. Each manure uses 750-1000 kilograms of human waste, and 500 kilograms of clean water is mixed at about 5 pm. 500 grams of potassium dihydrogen phosphate per acre, first dissolved in warm water, then mixed with 500 kilograms of water, water in the cracks. 2.5 kg of urea per mu, 10 kg of superphosphate, dissolved in a small amount of water, 500 kg of water to root. After dissolving 100 kilograms of ash per acre, soak for 5 hours, remove impurities, and irrigate 500 kilograms of water.
After checking the cracks, seeing the leaf color, and seeing the variety in the field, determine the topdressing time. If the cracks on the ridge surface of the sweet potato begin to fade and the leaf color fades, it can be topdressed. Topdressing time: Generally, summer sweet potato should be used before “white dew†after “potential potatoâ€; autumn sweet potato should be “before decoction†after “white dewâ€.
Method: Choose cloudy or sunny evening. Fertilizer should be fully mixed, and according to the weather and dry and wet conditions of the soil to prepare a good concentration of fertilizer, sunny days dry should be more thin, Tianyin wetting should be thicker. It is necessary to chase ridges and ridges one by one along the cracks to make them uniform and avoid leakage. While applying cracking fertilizer, sweet potato leaves are planted with 100kg/mu of plant ash to supplement K fertilizer, which can also increase the application effect of crack fertilizer.
