通过对多年生产经验的总结，在南疆沙漠地区推广了利用农毛渠。畦间田埂和农家庭院栽桑，与其他作物高低搭配，充分利用光、热、水、肥资源的立体农业体系。本文总结提出了这一体系内桑树的栽植形式和树型养成技术．分析讨论了农毛渠栽桑的技术特点和经济效益，建议进一步推广。

In the desert areas in south of Xinjiang, the production exeperience wassummed tlp during many years and a mode of mulberry cultivation on branch irrigationcanals, field ridges and farrnar courtyards was popularized to establish a kind of stereo agricutural system with other crops of dlfferent height in order to make full use of the resourses oflight, heat, water and fertilizer, This paper put forward the cultivative pattern and trainingform of rntllberry in the systenl .discussed the technical properties and economicaI benefit ofrnulberry cuItivation on the branch lrrigation canals and suggested that the technique be madefarther popularization.
