How to promote the early ripening of summer corn?

How to promote the early ripening of summer corn? Please introduce the methods to promote the early maturity of summer corn can use the following methods: 1. Foliar fertilization in the middle stage of corn growth, 0.3% potassium dihydrogen phosphate plus zinc, boron micro-fertilizer mixture can be sprayed to promote corn grain formation, improve stress resistance, and mature earlier. 2. timely prevention and control of diseases and insect pests to reduce the harm of diseases and insect pests to maize in the later stage, improve the utilization rate of light energy, and promote the transformation and accumulation of nutrients in summer maize. Therefore, it is necessary to do a good job in the control of corn brown spot, leaf spot, aphids and corn borer. 3. After going to the male every other line, "the corn has gone to the head, and he is as strong as an ox." After castration, corn can supply the nutrients and water needed for male ear flowering to the needs of female ear growth and development. Second, male flowers on the top of the plant, remove part of the male flowers to prevent shading, which is conducive to maize photosynthesis. So interline emasculation can speed up the ripening of corn. The method of emasculating: you can go to one line or one other line. The most suitable period for emasculation is when the tassel is just pulled out and can be held by the hand, and all the remaining tassels are removed after pollination. 4. except for empty plants, the plants and diseased plants that can not bear ears are removed, which not only saves water and fertilizer, but also helps ventilation and light transmission. 5. Peeling and drying the ear in the late milking stage of corn, gently peel off the bracts on the female ear of corn, so that the corn grain is directly exposed to sunlight, which can promote the nutritional transformation and dehydration of corn grain, and mature 7-8 days earlier. 6. during the corn wax ripening period, the corn is planed with the roots, transported out of the field and placed in the shady place behind the house or under the tree. it is best to pile up the soil and pour some water on the roots in order to maintain the green leaf function for a long time, promote the nutrients in the stems and leaves to be transported to the grain and increase the grain weight, the storage pile should not be too large, the stacking time should not be too long, 15 days is suitable for 20 days.
