Effect of Climatic Factors on the Yield of Aneurolepidium chinense (Trin.) Keng Community

Guo Ji-xun and Zhu Ting-cheng   

Abstract: According to the yield of Aneurolepidium chinense (Trin.) Keng community and climatic variations from 1978 to 1990, the relationship between the yield and climatic factors was probed by correlation analysis. The results showed that the correlation degrees of Σ7—8 months' precipitation, Σ6--8 months' precipitation/Σ6--8 months' temperature and Σ4—7 months' sunshine in relation to the yield were 0.47, O. 41 and 0. 35 respectively and the correlation was in the order of 0.47>0. 41>0. 35. Water was the main limiting factor affecting the community yield. The effect of interation of water and heat factors on the yield was also extremely remakable. The yield of A. chinense community was simulated by using multiple regression equations and periodic variance analysis, reaching a simulated rate over 90%.
