摘要
选用多种除草剂及组合对宁夏南部山区林业苗圃中的恶性杂草刺儿菜进行化学防除试验研究,结果表明:防除刺儿菜最好的药剂组合是力虎+速展,助剂为斩草除根。刺儿菜平均高度<10 cm时,用药量以力虎750 m L/hm^2+速展300 m L/hm^2为宜;平均高度为10~20 cm时,用药量以力虎1 125 m L/hm^2+速展450 m L/hm^2为宜;平均高度为20~50cm时,用药量以力虎1 500 m L/hm^2+速展600 m L/hm^2为宜;高度>50 cm时,用药量继续增加即可。然而,在刺槐苗圃喷施力虎会对刺槐产生毁灭性的药害,应禁止在刺槐苗圃使用力虎。
With multi-herbicide, chemical control study on Cirsium setosum（Willd.） MB. in forestry nursery in mountains of southern Ningxia Province was carried out. The result showed that the best combined herbicides were Qiuci and Suzhan with additive of Zhancaochugen. When average height of Cirsium setosum（Willd.） MB. was less than 10 cm, the herbicides should reach 750 m L/ hm^2＋300 m L/hm^2; when it was between 10 cm and 20 cm, herbicides should reach 1 125 m L/hm^2＋450 m L/hm^2; when it was between 20 cm and 50 cm, herbicides should reach 1 500 m L/hm^2＋600 m L/hm^2; when it was higher than 50 cm, increase the herbicides. However, Qiuci would destroy Robinia pseudoacacia L., so it should be forbidden in Robinia pseudoacacia L. nursery.
