摘要
为了研究遮荫对不同生长年限泰山黄精生长的影响,本试验以一年生、二年生泰山黄精为材料,设置5种不同程度的遮荫处理,并对不同处理下的泰山黄精农艺性状进行统计分析。结果发现,不同程度遮荫对不同生长年限泰山黄精的农艺性状均有一定程度的影响,在遮荫率为40%~60%处理下一年生和二年生泰山黄精的株高、叶片数、开花率、每株花序数及种子数量达到峰值,这为泰山黄精的规范化种植提供了一定的参考依据。
This experiment was aimed to study the influence of different degrees of shading on growth of Taishan Polygonatum with different growth years in order to guide its planting under forests.The annual and biennial Taishan Polygonatum were used as test materials,and treated with five different degrees of shading,then their agronomic traits were statistically analyzed.The results showed that each degree of shading had a certain degree of influence on agronomic traits of Taishan Polygonatum.Under the treatment with 40%~60%of shade rate,the plant height,leaf number,flowering rate,inflorescence number and seed number reached the peak.The results could provide bases for normalized planting of Taishan Polygonatum.
