Effects of Weed Control Methods on Grain Yield and Quality of Herbicide-resistant Rice Under Direct Seeding
摘要
Abstract
[Objective]The aim of this study was to investigate the effects of different weed control methods on herbicide-resistant rice growth and yield formation.[Method]Field experiments were carried out with the ALS herbicide-resistant varieties of conventional glutinous rice Zhennuo 19(Z19),indica restorer line rice Huazhan(HZ),conventional japonica rice Zhendao 18(Z18),soft rice K6(K6)and their corresponding herbicide sensitive wild-type varieties as materials.The method of direct seeding was adopted.Three weeding methods were employed,including,artificial-weeding(T1),imazamox-weeding(T2)and conventional-weeding(T3).[Result]The control effect of artificial weeding was the best,followed by metomiazol treatment,with weed control efficacies of 95.43%and 86.34%,which were 34.32%and 24.23%higher than that of conventional weeding at 40-day after treatment.In addition,the agronomic traits of tested rice varieties(number of tillers,heading rate,leaf area index,leaf area decay rate and dry matter accumulation)increased to different degrees,with no significant effect on SPAD value or rice quality.Compared with the conventional-weeding(T3),the yield of Zhennuo 19,Huazhan,Zhendao 18 and K6 in T1 increased by 35.0%,34.8%,31.9%and 28.8%,respectively,and the yield of corresponding rice varieties in T2 increased by 17.6%,15.9%,14.1%and 15.2%,respectively.[Conclusion]The above results indicate that selecting ALS herbicide-resistant rice varieties and applying corresponding herbicide control technology under mechanical direct seeding conditions can effectively control weeds and maintain high grain yield,which is a high-yield cultivation method worthy of promotion.关键词
