宿州市維桥区为了保护环境和提高耕地肥力,推广秸秆还田面积逐年增加,但是由于机械、技术等落实不到位,对玉米生长带来了一定的影响,維桥区农委对玉米密度、田间整齐度、可见叶、叶面积指数、病虫害发生等方面进行调查研究,提出解决意见,以供推广应用。 In order to protect the environment and increase the fertility of cultivated land, Weiqiao District in Suzhou City has been promoting the area of ​​straw returning to increase year by year, but due to the lack of implementation of machinery and technology, it has had a certain impact on the growth of maize. Field uniformity, visible leaf, leaf area index, the occurrence of pests and diseases and other aspects of research, put forward suggestions for settlement, for the promotion of application.
