At present, the spring maize in Qianxi area has entered the jointing stage, and it is a critical period for the production of corn, which is a period of water demand and fertilizer demand. The summer management of corn should be strengthened.
First, top-dressing corn topdressing should be based on nitrogen fertilizer, the best two times topdressing, that is, big bell-mouth acres of urea 20 kg topdressing, tasseling, silking acres of topdressing 10 kg of urea. If the topdressing is completed, it should be concentrated in the big bell mouth period, 30 acres of topdressing urea, plus 5 kg of potassium dihydrogen phosphate, can enhance plant resistance. Fertilizer fertilizer should not be too close to the roots of corn, should be applied to the middle of two rows of corn, after the application of soil, in order to reduce the loss of fertilizer efficiency.
Second, weeding and weeding of corn is a mid-till crop. Reasonable cultivating can not only effectively remove weeds, but also increase ground temperature and promote plant growth. Drought cultivating can destroy the surface capillary, prevent evaporation of the lower layer of water, play a role in drought protection; after cultivating after the rain, the soil compaction can be broken to accelerate the evaporation of soil moisture, play a role in flood control. The cultivator should not be too deep in summer, and 4.5 to 6 centimeters should be appropriate to avoid injury. For fields with severe grass damage, chemical weeding methods can be used. M. paraquat (200 mg without trace), 100 kg of water, directional spray weeding, and spraying, the nozzle should be installed with a protective cover to avoid the liquid Drift damages corn leaves and surrounding crops.
Third, timely irrigation and drainage of large bell-mouth corn is the critical period of water demand, in case of drought will have a serious impact on the yield, where irrigation conditions, watering should be promptly drought, to prevent "card neck drought." Spring corn has a long grain filling period, and “autumn drought†has a very serious impact on corn yield. Farmers have the notion that “spring drought is not dry, and autumn drought is reduced by halfâ€. If the corn is in drought during the grain filling period, it should be watered and drought-resistant in time. Although corn is a high-fertilizer crop, it is not tolerant to radon. If there is a large area of ​​accumulated water in the fields after rain, it should be drained in time to prevent premature aging of rot.
Fourth, pay attention to the inspection and treatment of pests and diseases This period of corn pests and diseases are mainly corn borer, armyworm and corn, large and small spot disease, should strengthen monitoring, timely and effective measures to prevent and control.
