摘 要: | 以长白落叶松播种苗(S1-0)圃地为对象,采用果尔、拿扑净和一定重量的水按4种不同配比的药液进行除草试验,结果表明:芽前杀草效果以“A35ml+B40ml+C”为最好,苗期喷施效果考虑幼苗受害率和杀草率,以“A30ml+B40ml+C”效果最佳。采用化学药剂除草较人工除草可提高工效5倍,除草667m^2可节约生产成本1120元。

Abstract: | Seedlings nursery of Larix olgensis( S1-0 )were taken as objects to conduct weed control test by useing oxyiluorfen, sethoxydim and a certain weight of water, according to four kinds of different proportion of liquid. The results showed that the best effect before sprout was "A35 ml + B40 ml + C" ;considering the seedling vic- timization rate and percentage of weed control , " A30 ml + tM0 ml + C" was the best effect during seedling stage. The work efficiency of chemical herbicide was 5 times more than manual work weed control, and it could save production costs 1 120 Yuan per 667 m^2. |
