Study on intercropping leguminous forages in orchard

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.
