| 摘 要： | 桃园林下对白花三叶草、紫云英、大巢菜、多年生黑麦草和蚕豆5种植物进行了栽培试验。结果表明:5种植物秋季种子播种出苗后至第二年5月上旬地上部生物量达到高峰,其中白花三叶草、大巢菜和紫云英的地上部生物量可达100 t/hm~2以上;5种植物对杂草均有一定的抑制作用,白花三叶草、大巢菜和紫云英对杂草的抑制作用明显,春季时对禾本科和阔叶杂草的抑制率均达80%以上;桃园种植生草植物后蜜蜂数量普遍增加,其中紫云英种植区蜜蜂数量增幅最高,达1 210.0%。综合其相对电子传递速率、光能利用效率和半饱和光强等参数分析,蚕豆、白花三叶草和紫云英较适宜于桃园林环境下栽培。

| Abstract: | The cultural experiments of Trifolium repens,Astragalus sinicus,Vicia sativa,Lolium perenne and Vicia faba were carried out in a peach orchard.The results showed that after seeded in fall,the 5 grass species’ aboveground biomass reached the peak in the early May of following year,and that of T.repens,A.sinicus or V.faba could reach above 100 t/hm~2;The 5 grass species had a certain inhibiting effect on weeds,and the efficacy of T.repens,A.sinicus or V.faba in controlling weeds was significant and could be over 80%in controlling gramineous and broad-leaved weeds in spring; The number of bees increased after planting the 5 grass species and the highest increment rate was 1 210.0%in the plot of planting A.sinicus.According to the above results and the analysis of such parameters as relative electron transport rate,efficiency of light energy utilization and half-saturation light intensity,T.repens,A.sinicus and V.faba were suitable for planting in a peach orchard. |
