摘要
在芒果园、龙眼园、荔枝园树下套种了山毛豆(Tephrosiacandida DC)、白花扁豆(Lablab purpureus)、圆叶决明(Chamaecrista rotundifolia)等9个牧草品种,对它们的生长速度、鲜草产量、茎叶比、风干率及营养成分等进行了观测和比较分析。结果表明,蟛蜞菊(Wedelia chinensis)、山毛豆、白花扁豆、大翼豆(Mac-roptiliumlathyroides)、罗顿豆(Lotononis bainesii)等5个品种在果园内种植,再生性好,鲜草产量较高,耐荫性强,粗蛋白含量高,动物喜食,并能抑制果园杂草生长,提高土壤肥力和促进果树生长,可以在该地区进一步推广应用。
Nine kinds of leguminous forages,including Tephrosia candida,Semen dolichoris,Chamaecrista rotundifolia、Alysicarpus vaginalis、Pueraria lobata、Stylosanthes dolichoris、Macroptilium lathyroides、Wedelia chinensis、Lotononis bainesii,were intercropped in mango,longan and litchi orchards and the growth speed,fresh yield,stem to leaf ratio,dry matter ratio and nutrient content of the legumes were measured.The results showed 5 legumes including W.chinensis,T.candida,S.dolichoris,M.lathyroides and L.bainesii performed good shading tolerance,regeneration,palatability and high crude protein content,and they also could promote the growth of fruit trees by inhibiting weed growth and increase the soil fertility.Therefore,they should be further extended in this area.
