近年来,随着农村劳动力的转移,直播稻在我国大范围的推广,同时杂草稻的危害也逐渐加强,不少地方出现杂草稻的危害,然而在有些地区对杂草稻的危害不够重视,因此,有必要对杂草稻的发生情况进行一次调查。通过此次调查,初步明确了南方杂草稻的发生情况,但是掌握信息不够全面,以后将继续加强对南方杂草稻发生情况的深入调查。 In recent years, with the transfer of rural labor force, direct broadcast rice has been widely promoted in our country. At the same time, the harm of weedy rice has been gradually strengthened. In many places, weedy rice has been endangered. However, the weedy rice is not endangered in some areas Therefore, it is necessary to conduct a survey on the occurrence of weedy rice. Through this survey, we initially identified the occurrence of weedy rice in the south, but the information was not comprehensive enough. We will continue to further investigate the occurrence of weedy rice in southern China in the future.
