Recently, stormy weather has frequently appeared, and this period is the critical period for the growth of summer corn. It is easily affected by bad weather and can easily cause corn lodging. In order to reduce flood damage and ensure the harvest of autumn crops, the reporter interviewed Yang Yinfu, a corn specialist at the Northwest A&F University. He gave five measures to strengthen corn field management after heavy rainfall.
Early drainage will eliminate the water accumulation in the field as early as possible, reduce soil and air humidity, and promote plant growth. In the early stage of corn, it is necessary to drain in time and flooding time should not exceed half a day.
Timely soils have been affected by stormwater, strong winds and other factors, resulting in the lodging of plots. In accordance with the actual situation, it is necessary to carry out soil conservation in time. Stems generally do not need to take remedial measures, so when the weather improves, it will automatically return to its upright state after a period of growth; the roots must be lifted immediately after the rain, and when they are raised, the stems and the ground must form a 30 to 50 degree angle. The roots of the corn are well-cultivated with earth, and the use of down-to-earth is practical; the stems are generally difficult to recover; the lighter lands are not easy to take rescue measures, and they can be allowed to grow naturally. For lands with severe stem folds, we must pay close attention to other types of crops. Fall crops to reduce losses.
Early application of Miaofei to long-flooded fields, flooding serious fields, timely recovery of Miao Fei, big bell-mouth period can be topdressing urea. Spraying high-efficiency foliar fertilizers and root-reinforcing agents at the same time as fertilization promotes transformation of seedlings, promotes root development, and promotes the restoration of growth. Late corn planting, drought, weak seedlings can be used to increase the timely application of available nitrogen fertilizer.
Pest control due to field water, plant damage, soil moisture saturation, air humidity, easily lead to various diseases. For the emergence of pests and corn fields, to symptomatic treatment, spraying once every 10 days, a total of 2 to 3 times the drug, can control field pests and diseases. At the same time, we must strengthen observation in the field and remove weeds in a timely manner. This can effectively prevent the occurrence and spread of the virus, and early detection and timely removal of diseased plants to bring out the field treatment.
After the cultivating and weeding rain, due to the large moisture content in the soil and the high temperature, the growth rate of weeds is obviously accelerated. If grass weeds are not cleared in time, it will cause grass shortage. Therefore, after heavy rain, severe weeds should be sprayed on the weeds in a timely manner, herbicide treatment can also be cultivator weeding, in order to ensure the normal growth of corn to do a good job of cultivator eradication, root and weeding.
