Weeding Effect of Different Herbicides at Different Periods of Sorghum and Effect on the Growth of Sorghum
摘要
Abstract
[ Objective ] The aim was to explore the weeding effect of different herbicides at different periods of sorghum and effect on the growth and yield of sorghum. [ Method] The weeding effect of Roundup, 38% Atrazine and Starane were observed at different periods of two sorghum varieties (Lunuo 8 and Luzhouhong 1) , such as seven days before transplanting, before transplanting, after transplanting and at the mid-term ploughing time, meanwhile effects on the growth and yield of sorghum were studied. [ Result] The other treatments had no phytotox- icity to sorghum except Roundup applied after transplanting and at the mid-term ploughing time. Roundup had the best weeding effect; Starane only had good weeding effect on wide leaf weeds; 38% Atrazine had slow weeding effect. Compared with water control, Roundup applied at seven days before transplanting and 38% Atrazine applied after transplanting could improve the yield and relative growth indexes of hybrid and conventional sorghum obviously. [Conclusion] The research result provides theoretical basis for the control of weed in sorghum yield.关键词
