How can seedling burn be prevented when planting corn in summer? Please explain the methods
When planting corn in summer, improper application of starter fertilizer makes summer corn prone to seedling burn, so first of all, choose the right fertilizer type and control the application rate. Urea and other urea-based fertilizers are not suitable as starter fertilizer, otherwise seedling burn easily occurs; a nitrogen, phosphorus and potassium compound fertilizer can be applied. Corn needs relatively little fertilizer at the seedling stage, so to reduce waste, the starter fertilizer application rate should not be too large, generally about 10 kg per mu; especially when sowing into moisture, the starter fertilizer application rate must be strictly controlled. Ensure separation between seed and fertilizer. When applying starter fertilizer, to avoid direct contact between seeds and fertilizer that causes seedling burn, mechanical sowing should keep the seed and fertilizer separated by 7-10 cm; with manual sowing, change fertilizer application below the seed to side-deep application or deep application in holes between seeds. Ensure soil moisture. For plots where starter fertilizer is applied, sow with sufficient moisture or water over the field after sowing, so as to "dilute" the starter fertilizer and, to a certain extent, reduce the seedling burn caused by a large amount of starter fertilizer.
