固体基质无土栽培方式对樱桃番茄生长发育的影响

以"1319"樱桃番茄为试材,在日光温室内研究了3种固体基质无土栽培方式(砂培、有机基质培和蛭石培)对樱桃番茄产量、果实品质、净光舍速率和植株生长的影响.结果表明,3种无土栽培方式的前期产量、总产量、单果鲜重和单果千重及株高均显著高于对照土壤栽培,部分测定项目的处理间差异还达到了极显著水平;3种无土栽培方式的总产量分别比土壤栽培提高了26%、35%和50%.但是,3种无土栽培方式的樱桃番茄果实可溶性固形物含量、果实维生素C含量、果实干物质含量与对照土壤栽培差异不大.在3种无土栽培方式中,仅蛭石培在总产量和株高上显著高于砂培.

Effects of Different Soilless Culture-methods with Solid Substrate on the Growth and Development of Cherry Tomato

Cherry tomato (Lycopersicon esculentum Mill.var.cerasiforme Alef.cv.1319) was used to investigate the effects of three kinds of soilless culture-methods with solid substrate on yield, fruit quality, net photosynthetic rate and plant growth under solar greenhouse in Tianjin. The results indicated that the early harvest yield, total yield, single fruit fresh-weight, single fruit dry-weight and plant height of three kinds of soilless culture were all significantly higher than that of soil culture, which consis...
