赤峰地区主栽作物除草剂施用情况

通过调查赤峰地区主栽作物除草剂施用情况，为粮田生态系统可持续发展提供一定的理论依据。首先确定有代表性种植谷子和玉米的旗县区，有针对性的调查谷子田和玉米田杂草发生情况和除草剂使用情况并进行总结。调查发现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，存在随意加大除草剂用量、推迟喷施的现象。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、绿色、可持续的优点，但在生产中并未普及。

Application of herbicides to major crops in Chifeng

Based on the investigation of herbicide application on main crops in Chifeng area, this paper provides a theoretical basis for the sustainable development of grain field ecosystem. Firstly, the representative planting areas of millet and corn were identified, and the occurrence of weeds and the use of herbicides in millet and corn fields were investigated and summarized. The investigation showed that there were many kinds of weeds in millet field and corn field in Chifeng area, and herbicides were widely used. However, 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, green and sustainable, but they are not widely used in production.
