我们在长期生产实践中 ,摸索出一整套除草剂使用技术。为充分发挥除草剂药效 ,特提醒农民朋友使用时切记 :一、严格掌握使用剂量 ,并准确量取。剂量小 ,除草效果不明显 ;剂量大 ,易产生药害。喷药时应退着均匀喷雾于土壤表面 ,切忌漏喷或重喷 ,以免药效不好或发生局部药害。二 In the long-term production practice, we explored a set of herbicide use technology. In order to give full play to the effectiveness of herbicides, remind peasant friends when using remember: First, strictly control the dosage, and accurately measure. Small dose, weeding effect is not obvious; large dose, easy to produce phytotoxicity. Spraying should be sprayed evenly on the surface of soil spray, avoid leakage spray or re-spray, so as to avoid ineffective or local injury occurs. two
