| 摘 要： | 目的]探究林下太阳辐射环境对人参生长发育的影响。方法]选取吉林省梅河口市吉乐林场内10个试验单位，测定其内的太阳直射辐射、散射辐射、光合有效辐射（PAR）及光谱辐射指标，以8年生林下参为试验材料，测定其形态指标及净光合速率（Pn）。结果]林下散射辐射日累计值在109．45～202．27W／m^2时，人参地上部分的生长与散射辐射呈显著负相关；林下参株高仅取决于PAR的大小，茎高、叶宽和叶面积与散射辐射呈显著负相关，而与PAR相关性不显著；茎粗与散射辐射和PAR均呈显著负相关；当PAR值接近时，红橙光和绿光含量高的试验单位，林下参Pn较大。结论]林下太阳辐射环境对人参的形态特征及光合生理特性均有较大影响。

| Abstract: | Objective] The aim was to study the effect of solar radiation under forest on growth and development of ginseng.Method] Choosing 10 experinent units of Jile Farm in Meihekou City in Jilin Province,the indexes of direct radiation,diffuse radiation,photosynthetically active radiation(PAR) and spectral solar radiation were determined.Taking 8 years ginseng under forest as material,morphological index and net photosynthesis rate(Pn) were determined.Result] When the daily accumulated value of diffuse radiatio... |
