玉米病虫害防治技术的应用

Application of Prevention and Control Technology of Corn Diseases and Pests

公主岭市是全国名列前茅的产粮大县,其中玉米在吉林省的粮食占比大,玉米产量受制约的因素多种多样,它会受到天气、管理水平、病害、虫害等因素的影响,其中病害、虫害影响是十分突出的。在广大农民追求高产量的同时,不科学、不合理的密植,过度追求产量而大量施用化肥,造成土壤板结,还有气候影响、工业污染等都为玉米病虫害提供了发展的契机,如果高度重视玉米病害、虫害,将会导致玉米产量大幅度下降。随着时代的发展、制药技术的发展,农民的田间管理水平的不断提高,玉米病虫害得到了有效的控制,但玉米病虫害防治仍存在以下的问题,需要针对不同问题提出相应的对策。

Gongzhuling City is one of the leading grain producing counties in China,Corn accounts for a large proportion of grain in our province.The yield of maize is restricted by many factors,including weather,management level,diseases and insect pests,among which diseases and insect pests are very prominent,while the majority of farmers are pursuing high yield,unscientific and unreasonable close planting,excessive pursuit of yield and heavy use of chemical fertilizers have caused soil hardening,as well as climate impact and industrial pollution,which have provided opportunities for the development of corn pests and diseases.If we do not attach great importance to corn diseases and insect pests,it will lead to a significant decline in corn yield.With the development of the times,the maturity of pharmaceutical technology,and the continuous improvement of the field management level of farmers,corn diseases and insect pests have been effectively suppressed.However,there are still some problems to pay attention to,but there are still some problems in the prevention and control of corn diseases and insect pests,which need to be analyzed and discussed according to different problems.
