为了探寻棉花生长期田间除草技术，我们采用禾草克五种浓度进行小区试验，结果显示：每亩用20g对棉田禾本科杂草和阔叶杂草都有良好的除草效果。 In order to explore the field weed-growing technology in the cotton growing season, we used five concentrations of graminex to conduct community trials. The results showed that 20g per acre had a good herbicidal effect on grassy weeds and broad-leaved weeds in cotton fields.
