摘要:
 滇黄精具有较高药用价值，是林下种植药用植物的首选。以马尾松人工林所形成的林缘、林隙、林内3种生境下种植的2年生滇黄精植株为试验对象，通过测定不同林下生境滇黄精叶片表型、光合色素质量分数及光合参数，比较分析在不同生境下的叶片表型及光合功能特性。结果表明，不同生境下滇黄精叶宽与比叶面积差异显著，表现为林隙>林缘>林内；不同生境光合色素(叶绿素a、叶绿素b、叶绿素a+b、类胡萝卜素)质量分数差异显著，均为林内>林缘>林隙；不同生境下滇黄精净光合速率日变化均呈“双峰”曲线，存在明显“午休”现象，其中林缘为气孔因素导致；林隙为气孔与非气孔因素共同影响；林内则为非气孔因素限制；林隙下的滇黄精光补偿点、暗呼吸速率较低，而光饱和点、日均净光合速率、最大净光合速率较高，表明其对光利用能力更强，即更有利于植株生长。因此，林下种植滇黄精的最佳生境为林隙，林缘次之，林内最差。
Abstract:
Polygonatum kingianum is the first choice for planting medicinal plants under the forest for its high medicinal value.In this experiment,2-year-old P.kingianum were planted in three habitats,including forest edge,canopy gap and understory of Pinus massoniana plantations.By measuring the leaf morphological characteristics,photosynthetic pigment mass fraction and photosynthetic parameters in different forest habitats,the leaf surface morphology and photosynthetic function characteristics in different habitats were compared and analyzed.The results showed that there were significant differences in leaf width and specific leaf area of P.kingianum in different habitats,manifested as canopy gap>forest edge>understory.There were significant differences in the mass fractions of photosynthetic pigments (chlorophyll a,chlorophyll b,chlorophyll a+b and carotenoids) in different habitats,which were understory>forest edge>canopy gap.The diurnal variation of net photosynthetic rate of P.kingianum in different habitats showed a "double peak" curve,and there was an obvious "midday break",in which the forest edge was caused by stomatal factors; the canopy gap was affected by both stomatal and non-stomatal factors; in the understory,it was limited by non-stomatal factors.The light compensation point and dark respiration rate of P.kingianum in the canopy gap were lower,while the light saturation point,daily average net photosynthetic rate and maximum net photosynthetic rate were higher.It showed that it had stronger light utilization ability,that is,it was more conducive to plant growth.Therefore,the best habitat for planting P.kingianum under the forest was forest gap,followed by forest edge,and the worst in the forest.
