| 摘 要： | 在果林下间作菊苣、紫花苜蓿（新疆大叶）、紫花苜蓿（驯鹿）、红三叶、鸭茅、无芒雀麦，对6种牧草的产量和光响应特性进行测定分析，研究不同牧草在果林的生长状况。结果表明：六种牧草产量的高低依次为菊苣>驯鹿苜蓿>新疆大叶>鸭茅>红三叶>无芒雀麦。利用叶子飘新模型15~16]对6种牧草的光响应曲线拟合表明菊苣、紫花苜蓿（新疆大叶）、紫花苜蓿（驯鹿）的光合能力较强，最大净光合速率均大于15μmol CO2.m -2.s – 1。六种牧草的光补偿点的大小为鸭茅<菊苣<新疆大叶<驯鹿苜蓿<无芒雀麦<红三叶，光饱和点为驯鹿苜蓿>新疆大叶>无芒雀麦>鸭茅>红三叶>菊苣；六种牧草在光量子小于400μmol m-2.s-1时Pn均值与第一茬鲜草产量存在显著相关关系。

| Abstract: | Cichorium intybus L.,Medicago sativa L.(Xinjiang big leaf),Medicago sativa L.(AC Caribou),Trifolium pratense L.,Dactylis glomerata L and Bromus inermis Leyss.were intercropped in orchard.The yield and photo-response characteristics of six forage were studied to analyze their growth under fruit forest.The result showed that the yield of six forage were in the order ofCichorium intybus L.>Medicago sativa L.(AC Caribou)>Medicago sativa L.(Xinjiang big leaf)>Dactylis glomerata L.> Trifolium pratense L.> Bromus ... |
