At present, continuous high temperature and drought are extremely unfavorable to the growth and development of corn. Therefore, in the field of corn management, the emphasis is on drought resistance, disease treatment, and pest control.
First, sowing corn in spring. At present, it has entered the period of flowering and grouting. At this time, dry and water shortages are likely to form empty poles, which lead to a lack of grain, resulting in reduced yields. It is imperative to strengthen irrigation and drought resistance in field tubes to meet the needs of corn growth and development.
Second, the late sowing of corn to strengthen water and fertilizer management, has entered the trumpet of corn to heavy ear fertilizer. Seeding corn after the end of June depends on the days when the spring seedlings apply less fertilizer and weak seedlings, and the weak seedlings are replanted to promote balanced growth. The size, height, and thickness of the seedlings should be as consistent as possible.
Third, the prevention and control of corn borer and larvae of warts. Late sowing of maize is carried out in the middle and late of this month. The use of agents: corn mash: with kilandan or seven swords or rice plus BT powder, watered thick spots cover the top of the heart. Prevention of corn downy mildew, the use of pharmaceuticals: Jinlei Jia Wei Wei sterilization or sterilization of Wei Jia metalaxyl or sterilized Wei Jia bacteria clearance, watered 120 kg spray.
Fourth, the late sowing of corn should pay attention to control of grass and weeds, and we must promptly remove the tiller seedlings and prevent seedlings.
