| 中文摘要: |
| 2014-2015年对广西6个主要城市麦冬草坪杂草调查结果表明, 麦冬草坪常见杂草有30科107种, 其中菊科最多, 有22种, 占总数的20.56%, 其次是禾本科13种, 占总数的12.15%。危害较严重的有15种, 依次为白花鬼针草、狗牙根、马唐、胜红蓟、香附子、铺地黍、阔叶丰花草、双穗雀稗、积雪草、龙葵、光鳞水蜈蚣、红花酢浆草、小飞蓬、银胶菊和升马唐。药剂防除试验结果表明, 24%甲咪唑烟酸AS 324 g/hm2、75%甲嘧磺隆WG 270 g/hm2、50%丁噻隆SC 4 500 g/hm2处理总草防效达80.37%~85.13%, 对麦冬的抑制率达31.69%~70.91%; 4%烟嘧磺隆SC 180 g/hm2、20%氯氟吡氧乙酸EC 360 g/hm2+4%烟嘧磺隆SC 90 g/hm2、5%精喹禾灵EC 90 g/hm2+10%双草醚WP 90 g/hm2、50%丁噻隆SC 2 250 g/hm2+20%氯嘧磺隆WP 22.5 g/hm2、75%甲嘧磺隆WG 135 g/hm2+24%乙氧氟草醚EC 337.5 g/hm2总草防效达81.07%~96.07%, 对麦冬的抑制率为1.53%~8.46%。 75%甲嘧磺隆WG 135 g/hm2+24%乙氧氟草醚EC 337.5 g/hm2总草防效达96.07%, 对麦冬的抑制率为3.31%, 适用于麦冬草坪杂草防除。 |
| 英文摘要: |
| The weed species in Ophiopogon japonicus lawn were investigated in Guangxi’s six major cities during 2014 and 2015 and the chemical control effects were also evaluated. The results showed that there were 107 weed species belonging to 30 families. Among them, 22 species belong to the family Compositae which accounts for the most (20.56%). 13 species belong to the family Gramineae which accounts for the second (12.15%). 15 species of weeds do serious harm to the lawn, including Bidens pilosa, Cynodon dactylon, Digitaria sanguinalis, Ageratum conyzoides, Cyperus rotundus, Panicum repens, Borreria latifolia, Paspalum paspaloides, Centella asiatica, Solanum nigrum, Kyllinga brevifolia, Oxalis corymbosa, Conyza canadensis, Parthenium hysterophorus, and Digitaria ciliaris. 24% imazameth AS 324 g/hm2, 75% sulfometuron-methyl WG 270 g/hm2 and 50% tebuthiuron SC 4 500 g/hm2 had the 80.37%-85.13% weed control effect and 31.69%-70.91% inhibition rate against O.japonicus. 4% nicosulfuron SC 180 g/hm2, 20% fluroxypyr EC 360 g/hm2+4% nicosulfuron SC 90 g/hm2, 5% quizalofop-P-ethyl EC 90 g/hm2+10% bispyribac-sodium WP 90 g/hm2, 50% tebuthiuron SC 2 250 g/hm2+20% chlorimuron-ethyl WP 22.5 g/hm2, 75% sulfometuron-methyl WG 135 g/hm2+24% oxyfluorfen EC 337.5 g/hm2 had 81.07%96.07% weed control effect and 1.53%-8.46% inhibition rate against O. japonicus While, 75% sulfometuron-methyl WG 135 g/hm2+24% oxyfluorfen EC 337.5 g/hm2 had the best weed control effect with the efficacy of 96.07%, and the inhibition rate against O. japonicus is 3.31%, which is suitable for the chemical control of weeds in O. japonicus lawn. |
