Potatoes are widely grown in some areas of China, and the economic benefits of potatoes are also high. How to apply fertilizer is summarized as follows:
1. Apply when planting potato chips, use superphosphate or apply a small amount of nitrogen fertilizer as seed fertilizer. However, it should be noted that nitrogen and phosphate fertilizers cannot directly contact seed potatoes. In many areas, the habit of seeding yam and ash is sown. In addition to the disease-preventing effect, the ash has a role in seeding.
2, based on organic fertilizer, the general dosage is 22.5 ~ 45 tons per hectare. The application method depends on the amount and quality of the organic fertilizer, and the amount of the organic fertilizer is 15 tons per hectare. The organic fertilizer can be applied to the seed potato block and then covered with soil. When the amount of coarse fertilizer is large, it should be applied and then ploughed into the soil. Phosphorus and potassium fertilizers should also be applied as base fertilizers.
