摘要
水稻旱播是针对春旱地区最适合的栽培技术,然而田间杂草种类不同于普通水田,化学除草是田间管理的关键。采用几种除草剂对水稻旱播田进行处理,结果表明,氰氟草酯对马唐的防效比二氯喹啉酸好,可达98.2%;2甲4氯对藜的防效比苯达松好,可达97.2%;氰氟草酯和2甲4氯复配对杂草的总防效最好,可达98.7%。
Dry - seeded rice is the most suitable cultivation technique for the spring drought area. However,weed species in fields in these areas differ from those commonly found in typical paddy fields, thus chemical control becomes the key to weed management. Several herbicides were evaluated in a dry - seeded rice field. Cyhalofop butyl was more effective than quinelorac on sativa,providing up to 98% control. MCPA was better than benzene on quinoa providing up to 97%. The total control effect of eyhalofop butyl and MCPA was best,at 99%. These results are useful for the improvement of weed control in dry- seeded flee.
