Investigation on Weed Occurrence and Herbicide Application in Millet and Corn Fields in Chifeng Area

本研究选择赤峰市有代表性的地区,调查了谷子田和玉米田杂草发生情况及除草剂应用情况。调查结果表明:赤峰地区谷子田和玉米田杂草种类繁多,除草剂广泛普遍使用,但在使用方式上略有差别;除草剂复混使用效果优于单一使用;生物除草剂与化学除草剂相比具有对环境污染小和可持续利用的优点,但在生产中并未普及。

In this study,the representative planting areas of millet and corn in Chifeng City were identified,and the occur-rence of weeds and the application of herbicides in millet and corn fields were investigated.The investigation showed that there were many kinds of weeds in millet field and corn field in Chifeng area,and herbicides were widely used,but there were some differences in the application methods.The effect of compound herbicide was better than single herbicide.Compared with chemical herbicides,biological herbicides have the advantages of less environmental pollution and sustainable use,but they are not widely used in production.
