8种除草剂对林业苗圃杂草的防除效果和苗木安全性试验
Effect of eight herbicides on weed control and seedling safety in forest nursery
摘要
Abstract
Experiment was carried out on the herbicide selection under the condition of basin cultivation and field. The results showed that these herbicides, 10% Bensulfuron-methyl ( 150 -750 g · hm-2) , 20% Oxyfluorfen · Pendimethalin(2 250 -3 150 mL · hm-2) ,33% Pendimethalin(1 200 -90 000 mL · hm-2) , 24% Oxyfluorfen (600 ~ 3 000 mL · hm-2) , Pinglil 1 (900 - 1 500 mL · hn-2),50% Isoproturon(2 250 -2 700 mL · hm-2),50% Butachlor(900 -2 700 mL · hm- 2), 30% Bensulfuron-methyl · Butachlor(900 - 1 500 mL · hm-2 ) ,had different weeding effect and weed control time, among which weeding effect of 24% Oxyfluorfen ( 1 200 mL · hm-2 ) could amount to 100% and its weed control time could maintain over 45 days. For the other seven kinds of herbicides, their weed control effect and weed control time were lower than the corresponding value of Oxyfluorfen. Furthermore, the seedling safety experiment indicated that 24% Oxyfluorfen(1 200 mL · hm-2) had little effect on emergence rate, early growth and root growth of the seedlings when applied before emergence of seedlings. Even if applyed before fast-growth stage (30 days after emergence of the seed-lings) , the whole year growth of seedlings was hardly affected.关键词
