摘　　要：为了对穴盘鸡毛菜基质栽培技术进行摸索,在清美数字化智能穴盘工厂开展不同穴盘规格及不同的种植密度对鸡毛菜的生长发育及产量性状的影响试验。采用72孔、128孔、200孔3种不同规格的穴盘进行鸡毛菜生产,单株质量分别为3.6 g、2.3 g、1.27 g,结果表明,随着穴盘孔数的减少,鸡毛菜长势更好,但3种不同规格鸡毛菜的单产分别为515.8 kg/667 m^(2)、663.5 kg/667 m^(2),562.4 kg/667 m^(2),因而综合生产成本及产量考虑,以128孔穴盘生长鸡毛菜最佳。In order to explore the substrate cultivation techniques of Brassica rapa,carried out a study in Tramy smart vegetable factory,this study evaluate the effects of different plug sizes and planting densities on the growth,quality and yield of Brassica rapa,set the three plug sizes(72,128,200 holes)in this study,fresh weight of aerial part of the Brassica rapa was seeded in 3 different plug sizes was 3.6 g,2.3 g and 1.27 g respectively.The results showed that with the reduction of the number of holes in the plug plate,the Brassica rapa grewd better,but the yield of the Brassica rapa that was seeded in the three different plug sizes was 515.8 kg/667 m^(2),663.5 kg/667 m^(2)and 562.4 kg/667 m^(2)respectively.Therefore,comprehensive considering the cost of production and yield,the 128 hole plug plate was the most suitable plug size for seeding Brassica rapa.
