| 中文摘要: |
| 安徽省是我国水稻主产区之一, 地处南北过渡带, 滨江临淮, 区位优势明显, 地理、气候环境多样, 不同水稻种植区逐渐形成以稗Echinochloa crus-galli、千金子Leptochloa chinensis、马唐Digitaria sanguinalis、杂草稻Oryza sativa等一种或多种恶性杂草为主的差异性分布群落, 且伴随耕作及生产活动不断发生演替, 对水稻的产量与品质构成严重威胁。目前安徽省稻田杂草防除仍以化学防控为主, 单一化学除草剂常年高频超量使用现象突出, 带来农业面源污染、农药残留、抗药性等一系列问题, 使水稻稳产增收、杂草可持续防控等面临严峻的挑战。笔者在前期跟踪监测和调查走访的基础上, 对安徽省稻田杂草发生、为害及防控现状进行了剖析, 并针对安徽省当前稻田杂草防除中存在的问题提出部分对策和建议, 以期为稻田杂草防控提供科学参考。 |
| 英文摘要: |
| Anhui province is one of the main rice-producing regions in China. Located in the transitional zone between the north and south, along the Yangtze River near the Huai River, it boasts a prominent geographical advantage with diverse geographic and climatic environments. Different communities with varying distributions of noxious weeds, such as barnyard grass (Echinochloa crus-galli), Chinese sprangletop (Leptochloa chinensis), common crabgrass (Digitaria sanguinalis), and weedy rice (Oryza sativa), have gradually formed in different rice planting areas. These communities undergo succession with ongoing cultivation and production activities, posing a serious threat to both the yield and quality of rice. Currently, the control of weeds in rice fields in Anhui province is still mainly based on chemical control. The phenomenon of high-frequency and excessive use of single chemical herbicides for many years is prominent, leading to a series of problems such as agricultural non-point source pollution, pesticide residues, and herbicide resistance. These issues pose severe challenges to the stable yield and increased income of rice, as well as the sustainable control of weeds. Based on preliminary tracking, monitoring, investigations, and visits, the authors have analyzed the occurrence, damage, and current situation of weed control in rice fields in Anhui province. Furthermore, the authors proposed strategies and suggestions to address the issues existing in the current weed control practices, aiming to provide scientific insights for weed control in rice fields. |
