Now it is the optimum period for the application of joint-fertilizer in maize. At this time, a large number of maize leaves begin to expand. The stalks are rapidly evolving, the stems and leaves grow vigorously, and the tassels begin to differentiate. The demand for nutrients becomes more urgent, and timely application of joint-fertilizer is needed. , can build a good skeleton for the later high-yield. So how much fertilizer is applied per acre? Experiments show that soil fertility is low, basal fertility is small, population is small, growth of seedlings is thin, and the yield per hectare is between 250 and 300 kilograms, and top dressing is 45% to 50% of the total topdressing fertilizer; moderate fertility plots and soil Good fertility, strong growth of seedlings, high uniformity of field population, dark green leaves, and yields of 550 to 650 kilograms of plots. To prevent seedling growth and ensure robust plant growth, jointing fertilizer can be controlled at 30% of the total fertilizer application rate. ~35% is good; the remaining fertilizer is reserved for tapping applications to meet the needs of rapid increase in trophozoites and continuous differentiation of male and female spikes. Soil fertility, base fertilizer, large populations, robust seedling growth, and high-yield plots with 650-750 kilograms of yield per mu, in order to prevent vegetative overgrowth, ensure stable growth of seedlings, maintain their plant energy conversion, and balance their metabolism. Easing the competition between groups and individuals on the living conditions, the top dressing should not be too much during this period. The jointing fertilizer generally accounts for 20% to 25% of the total fertilizer. Http://
