摘　　要：栽桑养蚕是我国农村的一项传统副业,至少已有5000年的悠久历史。传统的栽桑养蚕体制对自然资源和设备的利用不尽合理。例如,在江浙蚕区,每年桑树无叶期长达5个月之久,其间每1ha桑园大约接受1.26×10^(13)A mulberry-silkworm-livestock ecosystem was experimentally established in 1984 at Tai county of Jiangsu province. Winter crops have been interplanted as fodder in mulberry field during leafless seasons. Plant residues left by silkworm and fallen leaves have been used to feed goats. Chickens have fed on weeds and insects in mulberry field in summer and kept in silkworm breeding rooms in winter. The excrements of silkworms, goats and chickens have been applied as manures to mulberry and intercropping crops. Compared with traditional sericulture, this is one of successful homestead agroforestry'system, with better cycling of material and energy and better economic benefits, which is inereasingly practised in China today.
