杨树扦插苗的化学除草效果
Chemical Weeding Effect of Poplar Cutting Seedlings
摘要
Abstract
[Objective] The aim was to study technical measures of closed weeding at spikelet stage combined with chemical wedding at exhibi-tion leaf stage.[Method] Gramineous and broad-leaved weeds were controlled by different combinations of 23.5% Guoer,99% Jiujiuhong and 22% Chuheling at spikelet stage and exhibition leaf stage .[ Result] Through the experiment and combining production cost ,the herbicide formu-lation at spikelet stage was 20 mL 23.5%Guoer+25 mL 99%Jiujiuhong+40 L water,and the herbicide formulation at exhibition leaf stage was 35 mL 23.5% Guoer+15 mL 22% Chuheling+40 L water.The percentage of weeding for the two combinations were 85%-90%,which could save 70% of cost.[Conclusion] The results provide reference for production and business operation of poplar nursery.关键词
