解放以来,浙江的茶叶生产一靠政策,二靠科学,获得了迅速的发展,总产量和单产都有大幅度上升。但随着生产的发展,茶树病虫害也有加重的趋势。六十年代以来,尽管在病虫防治技术上有了提高,但病虫发生数量并未减少,为害程度仍很严重,新的病虫时有发生,防治成本直线上升,还出现茶叶中农药残留和害虫抗药性现象。这些现象的产生是和对综合防治的概念理解不全面,片面强调化学防治有关。为了进一步提高病虫防治技术水平,从本期起,特开辟《茶园病虫综合防治》讲座,计划从综合防治的概念,农业防治,生物防治,化学防治,防治指标,预测预报等方面分十个专题进行介绍,希望能对振兴我省的茶叶有所贡献。
Since the liberation, Zhejiang’s tea production has relied on policies. On the other hand, science and science have achieved rapid development. Both output and yield have risen sharply. However, with the development of production, pests and diseases of tea trees also have aggravating trend. Since the 1960s, despite the improvement in pest control technology, the number of pests and diseases has not decreased, the degree of damage is still serious, new pests and diseases occur from time to time, and the cost of prevention and treatment has risen linearly. Pesticide residues in tea also appear And pest resistance. The occurrence of these phenomena is related to the incomplete understanding of the concept of integrated prevention and control and the one-sided emphasis on chemical prevention and control. In order to further improve the technology level of pest control, starting from this issue, we will open a lecture on “comprehensive prevention and control of tea plant diseases and insect pests” and plan to shift from ten concepts of comprehensive prevention and control, agricultural prevention and control, biological control, chemical prevention and control, prevention and control indicators, forecast and forecasting Introduction of a topic, hoping to rejuvenate the contribution of tea in our province.
