赤峰地区谷田除草剂防效初探

A Preliminary Study on Millet Herbicides in Chifeng Region

以峰红谷为材料,选用5种除草剂对谷田杂草防效进行了田间试验研究。结果表明,各除草剂对杂草均有不同程度的抑制作用。在株防效上,喷药10 d、25 d时,浓度为200 g/667m^2的谷友、150 g/667m^2的莠去津效果最好;在株高上,莠去津相对于其他药剂的影响较为明显;在产量表现上,浓度为150 g/667m^2的2,4-D丁酯、谷友以及氟乐灵之间无显著差异性,但是150 g/667m^2的2,4-D丁酯较150 g/667m^2的莠去津显著升高。

In the study, a millet variety named‘Fenghonggu'was used for material and the control effects of 5herbicides on weeds in the area were studied. The results suggested that different herbicides have different degreesof inhibition to weed growth. The best results on control effect were 200 g/667m^210 day after 44% Monosulfuronplus Propazine WP spraying and 25 day after 150 g/667m^2 of Atrazine spraying. Compared with other drugs, effectof Atrazine on plant height was more significant. The millet yield were not significant different among spraying of 2,4-D Butylate, 44% Monosulfuron plus Propazine WP and Trifluralin at 150 g/667m^2, but the millet yield whichsprayed of 150 g/667m^2 of 2,4-D Butylate was significant higher than that of spraying of 150g/667m^2 of Atrazine.
