[目的]探讨影响苎麻生态区域适应能力的气候因素。[方法]在长江流域苎麻主产区选取5个不同生态区域分别作为试验点,考察了中苎2号的产量,并依据苎麻产量高低衡量了中苎2号对各生态区域的适应能力,最后分析了导致苎麻适应性差异的气候因素。[结果]各试验点产量差异较大,最高和最低产量差异达到2.3kg/20m2,且这一结果在2年试验中可以很好的重复。结合各生态区域的气候因子分析发现,中苎2号产量与其生长期间降水量、日照时间和相对湿度均呈显著相关性,其中长江流域不同生态区域日照时间和降水量可对中苎2号起到增产作用,而相对湿度则会对中苎2号起到减产作用。[结论]环境气候因子降水量、日照时间和相对湿度差异是导致苎麻在长江流域不同生态区域适应性差异的一个重要因素。
[Objective] The research aimed to discuss the climatic factors that affect the adaptability of ramie ecosystem. [Method] Five different ecological regions were selected as the experimental points in the main ramie producing areas of the Yangtze River to investigate the yield of Zhongzhu 2 and the adaptability of Zhongzhu 2 to each ecological zone was measured according to the yield of ramie. Finally, The climatic factors that led to differences in adaptability of ramie were analyzed. [Result] The yield of each experiment point was quite different, the difference between highest and lowest yield reached 2.3kg / 20m2, and this result could be well repeated in the 2 years test. According to the climatic factors analysis of various ecological regions, it was found that the yield of Zhongzhu 2 was significantly correlated with the precipitation, sunshine duration and relative humidity during the growth period. The sunshine hours and precipitation in different ecological regions of the Yangtze River could be controlled by Zhongzhu 2 To increase the role of production, while the relative humidity will play on the 2nd cut in the amount of Limousin effect. [Conclusion] The difference of precipitation, sunshine time and relative humidity of environmental climatic factors is an important factor leading to the adaptability of ramie in different ecological regions of the Yangtze River.
