For the summer corn with single base fertilizer, in order to improve the fertilizer efficiency, organic fertilizer and some chemical fertilizers are generally mixed and applied, and the effect of concentrated ditch is best. Micro-fertilizers such as boron, molybdenum and zinc can be applied as base fertilizer. The specific dosage per mu is as follows: 1 kg of borax, 1 kg of molybdenum sulfate, and 1.5-2 kg of zinc sulfate. It is difficult to apply base fertilizer to the land of fertilization of corn, and the application of seed fertilizer can be adopted to solve the problem of nutrient supply. A small amount of farmyard manure (soiled) can be used as a seed fertilizer or urea as a seed fertilizer, but seed and fertilizer must be isolated to prevent injury. Urea should be used in 3-4 kg per mu. The period, frequency and quantity of topdressing and topdressing should be considered comprehensively based on factors such as the appearance of corn, the period of fertilizer requirement, and the growth period. Phosphorus and potassium fertilizers have long-term effects, and the demand for corn is relatively large in the early stage. It can be applied as a base fertilizer or a seedling fertilizer once, and 25-35 kilograms of phosphate fertilizer per acre and 10-15 kilograms of potassium fertilizer. The topdressing method of nitrogen fertilizer can adopt the three-step topdressing method of light chasing seedling fertilizer, heavy chasing ear fertilizer and compensatory grain fertilizer: the seedling fertilizer accounts for 30% of the total topdressing amount, and it is applied in the period from the fixed seedling to the jointing stage, and there are strong seedlings and seedlings. The role of strong stalks; panicle fertilizer accounts for about 50% of the total topdressing amount. In the large trumpet period of corn, the ear can be large and large, which lays a foundation for high yield of corn. The grain fertilizer accounts for 20% of the total topdressing amount. The application period ensures the supply of nutrients in the late growth stage of corn, prolongs the functional period of green leaves, and promotes the grain yield and grain weight to obtain high yield.
