岷当气候生态适应性研究

目的:进行岷当气候生态适应性的研究,为当归种植基地建设提供科学的参考依据。方法:采用田间试验研究当归气候生态适应性,用积分回归统计方法研究气象条件对当归产量的影响。结果:选取≥0℃积温和年降水量为主导指标,海拔高度为辅助指标,单产和成品率为参考指标,确定出气候生态区划综合指标体系。结论:根据气候相似原理和主导指标叠加的结果,结合辅助和参考指标,对当归进行了最适宜、适宜、次适宜、可种植和不宜种植区等5级气候生态适生种植区划,并提出提高气候生态资源利用的途径。

Study on eco-climatic applicability of Angelica sinensis

OBJECTIVE: In the interest of establish planting base of Angelica sinensis on a large scale, enhance economic benefit, and improve decision-making reasons, the eco-climatic applicability of A. sinensis was studied. METHOD: Using integral regression, eco-climatic applicability and the effect of meteorological conditions for the yield of A. sinensis' were analysed by field experimental data. RESULT: Selected > or =0 degrees C accumulated temperature and annual precipitation as leading index, altitude as assistant index, yield and rate of finished products as reference index, the integrated eco-climatic division index and the planting division applicability of A. sinensis was confirmed. CONCLUSION: Accordancing to theory of climate similitude and leading index summarisation, combining with assistant index and reference index, the integrated division index of eco-climate was confirmed. The planting division of co-climate applicability was divided into 5 grades as best suitable, suitable hypo-suitable, just suitable and no suitable regions. At the same time,the way to enhanced utilizing efficiency of eco-climate resources was brought forward.
