我国桑树栽培技术的现状及发展对策

桑树栽培技术的进步，表现在优良桑品种的普及，实生桑园的实用程度提高，无性繁育技术的改进。密植速成桑园和立体栽培技术的确立及节本技术的应用。主要存在问题是，新技术新成果应用和以节本增效为目的实用技术偏少；桑园经营规模偏小。发展对策是，根据不同的生态环境，确立类型不同的栽培技术体系；加速桑树种质资源的利用，选育优质高产桑品种；重视防治新技术的研究与应用；加强节水、节本和提高叶丝转化率栽培技术及高技术的研究和应用；重视适度规模经营和劳动者素质的提高。

STATUS QUO OF MULBERRY CUULTIVATION TECHNIQUE AND ITS DEVELOPMENT STRATEGY IN CHINA

The progress of mulberry culture techniques showed as:(i)population of high quali-ty mulberry varieties;(ii) raising of practical level of mulberry seedling field;(iii) im-provement of asexual reproduction technique;(iv)establishment of dense planting andquick mulberry plantation and three-dimensional cultivation technique;(v)application ofcost-saving technique.The main problems existed are:no much application of new tech-niques and achievements and a few numbers of practical techniques aiming at saving costand promoting efficiency,and a small scale of mulberry field management.The counter-measures to bring about the development are as follows:(i)To determine mulberry culti-vation technique system according to different ecological environment;(ii)To increaseapplication of mulberry seed resources and breed more highquality and high-yield vari-eties;(iii)To pay great attention to the research and application of disease&insect pre-vention;(iv)To strengthen the research and application of both mulberry plantationtechniques which aim at saving water and cost and increasing the ratio of leaf to silk andhigh-newteches(including computer and biological techology):(v)To think highly of ra-tional scale management and enhancing of quality of the workers.
