摘　　要：为探寻永州市水稻生产过程中适宜的化控剂,以水稻品种甬优6708为试验材料,设置了4个不同的化控剂处理及1个清水对照处理,比较了不同处理水稻的节间长度、抗倒伏及产量情况。结果表明,不同化控剂对水稻抗倒性及产量的影响各不相同,4种化控剂均可降低水稻对的倒伏比例,仅劲丰谷德可缩短水稻节间长度及株高,提高水稻产量。综合各因素考虑,建议在永州市水稻生产过程中使用劲丰谷德作为化控剂较为合适。In order to explore suitable chemical control agents for rice production in Yongzhou City,rice variety Yongyou 6708 was used as the experimental material,four different chemical control agents and one clear water control treatment were used to compare the internode length,lodging resistance and yield of rice under different treatments.The results showed that the effects of different chemical control agents on lodging resistance and yield of rice were different.All the 4 chemical control agents could reduce lodging ratio of rice pairs,and only Jingfenggude could shorten internode length and plant height of rice and increase rice yield.Considering all the factors,it is suggested to use Jingfenggude as chemical control agent in rice production in Yongzhou City.
