湄潭县在1975年使用过除草剂,效果不佳。化除防效虽显著,但受海拔气温等地区性条件的影响较大。如在湄潭县高海拔山区,屡用均遭失败,致使化除在山区难以推广。因此在湄潭偏僻山区推行化除还是个新课题。鉴此,我们根据本县仅有的除草剂作了不少试验,以寻求在山区的使用技术,取得显著成效。在此基础上,我们还不断扩大试验和推广,特别是1981～1984年,在高台区和城关区试验和推广,成效尤佳,深受农民的欢迎,使化除面积迅速扩大。自1981年在农村各户推广415亩后,至1984年发展到1675亩,四年在农村各户推广面积共达2733
Meitan County used herbicide in 1975, the effect is not good. In addition to significant anti-effect, but by the altitude of the regional conditions such as temperature greater impact. As in Meitan high altitude mountainous areas, repeated use have failed, resulting in the addition of difficult to promote in the mountains. Therefore, it is still a new topic to promote the elimination of the remote mountainous areas in Meitan. In view of this, we have done a lot of experiments based on the only herbicides in this county to seek the use of technologies in the mountainous areas and achieve remarkable results. On this basis, we have also continued to expand our trial and promotion. In particular, from 1981 to 1984, we experimented and promoted in Gaotai District and Chengguan District. The results were particularly effective and were greatly welcomed by peasants. This has resulted in the rapid expansion of Huazhou area. Since the promotion of 415 mu of rural households in 1981, it has grown to 1,675 mu in 1984 and reached 2733 in each of the four years in rural areas
