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。 Taking Feng-Feng Valley as material, five herbicides were selected to study the field weed control effect in the valley. The results showed that each herbicide had different degree of inhibition on weeds. In the control effect of the strain, Guiyou at a concentration of 200 g / 667m ~ 2 and the atrazine of 150 g / 667m ~ 2 had the best effect on the 10th and 25th days after spraying. On the height of the plant, The effects of other chemicals were obvious. There was no significant difference in the yield between 2,4-Dbutyl, Guyou and trifluralin at a concentration of 150 g / 667 m ~ 2, but no obvious difference was found between 150 g / 667 m ~ 2 Of 2,4-D butyl ester than 150 g / 667m ~ 2 of atrazine significantly higher.
