空心莲子草的化学防治研究

本试验通过选用5种不同药剂(组合),即百草枯、使它隆、使它隆 洗衣粉、使它隆 食盐、使它隆 草甘膦,对空心莲子草进行化学防治,并对结果进行显著性测验。结果显示:其2次除草的总株防效分别可以达到98.9%、94.62%、92.22%、91.18%、90.03%,2种浓度的株防效平均值分别为95.33%、91.46%,并且,在第2次施药中,后3种没有显著效果,只需进行一次除草即可;由此表明:使它隆 食盐组合是最佳的除草方法。

Study on chemical control on Amararanthaceae philoxeroides

The effects of 5 herbicide(combination),including paraquat,starane,starane detergent,starane salt and starane glyphosate on controlling Amararanthaceae philoxeroides Griseb were compared and the result was analyzed by difference significance test.The rusult showed that the general controlling effects could reach to 98.9 %,94.62 %,92.22 %,91.18 % and 90.03 % after 2 times weeding and the average controlling effects by 2 kinds of density herbicide(combination) was 95.33 % and 91.46 %.The differences of the first weeding and the second weeding by starane detergent,starane salt and starane glyphosate were not significant,so one time weeding could get better effect.It was the best methods that the starane adding to salt was used to control A.philoxeroides Griseb.
