摘　　要：[目的]探索与直播青菜栽培技术相配套的播种速度。[方法]以青菜品种苏州青2号为供试品种,利用荷兰AL-640-SNT蔬菜气吸式精密播种机直播,设计4种播种速度:高速1档、高速2档、低速3档、低速4档,以研究播种速度对直播青菜出苗的影响。[结果]播种速度为低速4档最有利于直播青菜的出苗。[结论]该研究可为上海农场大面积推广直播青菜机械化栽培技术提供技术参考。[ Objective ] Tile aim was to explore the corresponding sowing speed of directly sowing vegetables. [ Method ] Taking Suzhouqing No. 2 as tested variety, and using The Dutch AL-640-SNT Type Vegetable Precision Suction Seeder, 4 kinds of sowing speeds（ High speed 1 file, high speed 2 file, low speed 3 file and low speed 4 file, resp. ） were designed to study the effects of sowing speed on seedling emergence of directly sowing vegetables. [ Result] Low speed 4 file was most favorable of seedling emergence of directly sowing vegetables. [ Conclusion] The study provides a technical reference for promoting directly sowing vegetables mechanized cultivation of Shanghai Farm in a large scale.
