通过成都市超高茬麦套稻秸秆全量还田栽培技术试验示范,探索该技术应用的关键环节,分析关于成熟期延迟、化学除草效果较差、田间杂株较多等存在的主要问题,提出要注意水稻品种的选择、除草剂的选择与应用、前1年水稻收获时秸秆的及时处理等相对应的技术措施,最后阐明该技术的应用前景。
Through the experiment and demonstration of the full straw returning straw cultivation in Chengdu, this paper explored the key aspects of the application of the technology, analyzed the main problems about the delay of ripening, the poor chemical weed control effect and the large number of hybrid plants in the field. Attention should be paid to the selection of rice varieties, the selection and application of herbicides, the timely treatment of straw during rice harvesting in the previous year, and other corresponding technical measures. Finally, the application prospects of the technology are clarified.
