边境和林区防火道灭生性化学除草技术的研究从1974年开始到现在已经进行了五年。通过室内外的大量试验与研究,已经肯定了适合该地区的既经济、药效又好的以镇草宁为主体的复合配方及经济用药量、最佳施药期,同时对喷洒工具也作了些试验和研究。通过试验和研究,证明化学除草开设边境和林区防火道,确实是一种质量好、速度快、成本低的新途径,深受广大群众欢迎。现把有关技术报告如下,仅供参考。一、基本情况试验区位于大兴安岭南麓内蒙古科右前旗西部,为蒙古草原的过度地段。地势平缓,海 The research on the extinction chemical weed control technology for the fire protection of the border and forest areas has been going on for five years since 1974. Through a large number of experiments and studies both inside and outside, it has been confirmed that an economical and effective compound prescription and economical dosage, the best application period, and the spraying tools suitable for the area are suitable Some experiments and research. Through experiments and studies, it has been proved that chemical weeding provides a new way of good quality, high speed and low cost by opening borders and forest fire prevention tunnels and is well received by the general public. The relevant technical report is as follows, for reference only. First, the basic situation The pilot area is located in the southern foot of Daxinganling, Inner Mongolia Branch right before the western banner, for the Mongolian steppe over the lot. Flat terrain, the sea
