适应气候变化科学利用生态环境发展蚕桑

Analysis of the Climate and Ecological Environment about the Development of Silkworm Industry in Yangcheng County

通过对阳城县气候历史资料的调查分析和对蚕桑生产情况的调研，分析了生态环境对蚕桑发展的重要性。认为阳城蚕桑生产需适应气候变化，及时抓住冬春变暖，夏季变凉，无霜期变长，冬夏降水增加的生态环境，调整生产布局，改进管理技术。气候变暖不仅有利于桑树生长和安全越冬，同时也增加了桑树、桑蚕相应病虫害的越冬能力和危害行为的超常性，如低温冻害、高温干旱、低温连阴雨等，这些都有可能导致桑树、蚕作的突发性灾难和病虫害的暴发。本文在桑管技术、养蚕布局、防虫防病等方面提出了应对措施。

Through analyzing the climate condition and investigating the development of silkworm industry, the importance of ecological environment to the development of silkworm industry is analyzed in this paper. The study shows that the warming climate change is beneficial to growth and safe overwinteringof mulberry trees, meanwhile, it provides better condition for diseases and pests surviving. So, we must adjust arrangement, improve management promptly to adapt to the climate change. Some concrete measures are presented.
