1. Deep application of base fertilizer. Acre of high-quality decomposed farmyard manure 1000-1500 kg, corn special formula compound fertilizer 40 kg, potassium sulfate 5 kg, fertilizer applied to the middle of two pond corn, should not be in contact with seeds.
2. Lightly apply seedlings. When the corn grows to 6-7 leaves, 10 kg of urea is applied to the mu, and the weak seedlings are applied more, and the strong seedlings are correspondingly less applied.
3, heavy pursuit of panicle fertilizer. When the corn grows to 10 to 11 leaves, it has entered the stage of young panicle differentiation. At this time, the seedling grows fast and absorbs more nutrients. It is a key period for corn to be fertilized, and 30 kg of urea is applied to the mu to effectively promote the large number of grains.
4, supplement the application of granular fertilizer. When the plant is pollinated, it enters the filling period. According to the situation, 8 to 10 kg of urea and 10 to 15 kg of potassium sulfate can be appropriately applied per acre to increase the grain weight.
In short, corn fertilization must be based on organic fertilizer, rational application of nitrogen, phosphorus, potassium, scientific fertilization methods, improve fertilizer utilization, in order to increase production and income.
