How to manage planting corn?

How to manage planting corn? Please give suggestions that Rain Water is too much, and the occurrence of corn diseases and weeds will be more serious than in previous years. Therefore, the following suggestions are put forward for the planting and management of corn this year. 1. Strengthening the prevention and control of diseases at seedling stage due to more Rain Water, high soil moisture and lower ground temperature, the emergence date of maize will be relatively slow, which increases the possibility of rotten seeds and dead seedlings of maize. The key point of prevention and control is seed coating. 2.5% water suspending agent can be selected. The usage is as follows: a bag of Xerox (10ml), 100ml ~ 150ml of water, pour into an enamel basin or plastic bag, then pour 3kg ~ 5kg of corn seeds, stir or shake hard, so that the liquid is uniformly wrapped on the surface of the seed. Wrapped seeds can be sown in time without drying. 10 ml phoxim or methyl isomaliphate can also be added to the solution to control underground pests. 2. the technology of weed damage control is rainy in summer, and it is not conducive to artificial weeding, so chemical weeding is the first choice this summer. The following weeding methods are recommended according to different maize sowing methods. Wheat interplanting with corn is recommended to first kill stubble, remove weeds that have already emerged in the field, and then spray pre-seedling herbicides such as du A mixture, herbicide, corn treasure, Yucaojing, Qiaochang Yuchangsi, and so on. If it is too late to kill stubble or save labor, you can also choose 25% grams of tracer-free water agent after the corn has grown to 4 leaves, directional spray weeding. According to the number and size of weeds in the field, 125ml ~ 175ml is used per mu and 40kg ~ 60kg to water. When spraying, put a protective cover on the sprinkler and keep the sprinkler as low as possible to avoid spraying liquid on the corn. Direct seeding corn in wheat field before sowing corn after wheat harvest, there are a large number of weeds in the field before sowing. The weeding technique of "one kill one letter" can be adopted. That is, before the emergence of seedlings after corn sowing, use du A mixture, herbal water, Maibao, Yucaojing or Qiaochang Yuchangsi 150ml ~ 200ml per mu, mixed with gram untraceable 25% water agent 50ml ~ 80ml, 40 kg ~ 60 kg of water ground spray. Gram without trace can kill all kinds of weeds that have emerged, and du A mixture or herbicide water can effectively control the emergence of ununearthed weeds.
