The 7-leaf stage of maize enters the jointing stage, which is the optimum period for applying jointed fertilizer. At this time, the corn leaves are fully expanded, the stems are rapidly elongated, the stems and leaves grow vigorously, the tassels begin to differentiate, and the demand for nutrients is increasing. Urgently, timely pursuit of joint fertilizer, can build a skeleton for the late high yield. So how much fertilizer is applied per acre? The experiment shows that the soil fertility is low, the base fertilizer is small, the population is small, the seedlings grow thin, the yield per acre is 250-300 kg, and the topdressing amount is 45%-50% of the total topdressing amount; medium fertility land, soil The fertility is better, the seedlings grow robustly, the field group is highly uniform, the leaves are thick green, and the yield per mu is 550-650 kg. In order to avoid the growth of the seedlings and ensure the stable growth of the plants, the jointing fertilizer can be controlled at 30% of the total topdressing amount. ~35% is good; the remaining fertilizer is reserved for earing application to meet the need for a sharp increase in vegetative body and continuous differentiation of the male and female ears. High-yield soil with high soil fertility, large fertilizer, large population, strong seedling growth, and high yield of 650-750 kg per mu. In order to prevent the growth of vegetative bodies, ensure the steady growth of seedlings and maintain the energy conversion of plants and the metabolic balance of substances. To alleviate the competition between the group and the individual on the living conditions, the topdressing should not be too much in this period, the jointing fertilizer generally accounts for 20% to 25% of the total topdressing amount; the remaining fertilizer is reserved for attacking and attacking, which is conducive to the promotion of spikes. Increase grain weight and high yield. Disclaimer: Some articles on this website are transferred from the Internet.
