Pouring the key water corn from the tasseling stage to the mature stage at the late growth stage, in which the water requirement intensity is the highest during tassel flowering period. If the water shortage will lead to infertility during the maize flowering period, it will not be normal pollination and can easily cause baldness, lack of grain. Even empty stalks phenomenon; grouting to maturity is also an important period of corn water demand, this period of water shortage will directly lead to a decline in corn grain weight.
The application period of scientific fertilization of granular fertilizer is from tasselling to flowering, and the total amount of topdressing N fertilizer is 15%~20%, and Mushi urea is 5~7.5 kg. In the later stage of maize, foliar spraying fertilizer can significantly increase the grain weight, 0.2-0.25 kg of urea per mu, 0.1-0.15 kg of potassium dihydrogen phosphate, and 50-75 kg of water.
Prevention and control of pests and weeds at the ear stage of maize prone to leaf spot, rust, bacterial wilt, smut, and smut, and can be controlled by sprays of pharmocycin, triadimefon, carbendazim, mancozeb, and others. Spray it once every seven days, usually 2 to 3 times depending on the condition. For corn rough dwarf disease and dwarf mosaic disease, serious diseased plants should be removed timely and taken out of the field for destruction. For the third-generation armyworm, when 100 insects have 120 insects, 50% phoxim EC can be sprayed and used for 1500 times. Excessive weeds in the field can be controlled by chemical herbicides in corn fields. After the 4th leaf stage of weeds, 100-200 ml per mu can be used without trace, 25-50 kg watered, and sprayed in the corn row.
Artificial pollination and detasseling, if there is continuous high temperature, little rain and sunshine, it is best to artificially assist pollination in order to improve corn seed setting rate. Maize detasseling can play a role in the prevention and control of diseases and insects, increase the light transmittance, promote the early maturing of corn, and significantly increase the yield.
Appropriate late harvest based on the reality of the postponement of the corn growth period this year, on the premise of not affecting the normal sowing of autumn sowing seeding, timely timely receipt, promote corn grouting and postcooking, reduce water, improve quality, increase production. It is one of the important production increase measures for maize that is efficient and easy to implement. Studies have shown that the harvest of corn in the dry leaves of the twilight is more yellow than that of the yellow leaves. The 1000-grain weight is increased by 15% to 20%, and the maize yield can be increased by 50 to 100kg per mu. Therefore, it is advisable to harvest the corn as late as possible without affecting the normal wheat breeding. At present, the summer maize is about to enter the late growth stage. The central task is to create good environmental conditions for flowering, pollination and fruiting, increase the photosynthetic efficiency, enhance the physiological activity of roots and leaves, prevent premature decay, strive for the maturity of living trees, and increase grain weight.
