摘要
[目的]研究荥经县野生环境种植天麻的适宜海拔范围。[方法]利用泥巴山和荥经气象站1981～2010年气象观测资料，通过相关分析和直线回归方法得到各季平均气温垂直递减率，采用内插法计算出泥巴山北坡1000～2000 m的平均气温和降雨量，通过对泥巴山野生天麻的生态气候环境分析，在保证优质兼顾产量的条件下，研究其生长适宜的海拔范围。[结果]根据天麻正常生长发育、越冬休眠对温度、水分条件的要求，在保证优质兼顾产量的条件下，确定出荥经县野生环境种植天麻的海拔为1300～1800 m。[结论]该研究为荥经县仿野生天麻的种植、农民增收、山地立体农业气候资源的高效利用提供参考。
Abstract
Objective] To study suitable elevation for wild Gastrodia elata in Yingjing County.[Method] By using meteorological observation data of stations Niba Mountains and Yingjing during 1981 -2010 , the vertical lapse rate of average temperature in each season was obtained through correlation analysis and linear regression method .Average temperature and precipitation at the north slope of Niba Mountains at 1 000-2 000 m were calculated by using interpolation method.According to the analysis of ecological and climatic environment of wild G.elata in Niba Mountains, its suitable elevation was studied based on the premise that its quality and quantity were ensured.[Result] According to the demands of water and temperature for the normal growth and development ,and overwintering dormancy of G.elata, wild G.elata should be planted at 1 300-1 800 m in Yingjing County based on the premise that its quality and quantity were ensured.[Conclusion] The research can provide refer-ences for the planting of imitation wild plants, increase of farmers’ income, and efficient utilization of three-dimensional agricultural climate re-sources in mountains.
