湖南山区发展苎麻的气候生态环境优势

SUPERIORITY OF CLIMATIC ECO-ENVIRONMENT FOR RAMIE GROWTH IN THE MOUNTAINOUS AREA, HUNAN PROVINCE

分析了湖南山区芒麻生长的气候生态环境条件，探讨了在山区加大竺麻生产力度的可能什，井就湖亩山区合理安排芒麻十产棵出了律议．

The climatic eco-environment indexes of the heat quantity,sunlight,water and wind for the growth of ramie plants were studied comparetively by analyzing the climatic eco-environment conditions in the mountainous and of Hunan Province. The results showed: 1. The heat quantity and sunlight indexes of mountainous area were almost the same as those of lake area,but there was more diffused and scattered sunlight in the mountainous area than in lake area, which brought forth higher photosynthetic efficiency, softer ramie fiber and better fiber quality; 2. There were more rainfalls in the mountainous area than in the lake area, especially during the second and third stages of ramie growth,which brought forth better water conditions for the ramie growth, because of more foggy days and higher relative moisture; 3. There were less windy days in the mountainous area which brought forth less wind injury. It was suggested that growing ramie plants at 600-700m uellbe better, considering the climatic eco-environment factors metioned above.
