Effect of intercropping forages on root growth of fruit tree and orchard ecology

摘要

Intercropping forages in young orchards not only could fully utilize the land resource to solve a conflict between orchard and pasture, but also could improve the microclimate of hilly orchards ( Qi et al, 1993 ).In contrast, some articles reported that planting mulch grasses in orchard could lead to conflicts of competing water and nutrients between grasses and fruit trees (Catzeflis et al, 1997).This paper investigated the root distribution of forage‐orchard compound system and effects of intercropping legume forage Chamaecrista sp p.on the orchard ecology to provide scientific basis for water and fertilizer management of orchard.
