摘　　要：试验通过控制不同种植密度,研究不同摘心位置对温室番茄光合作用、产量以及品质的影响。结果表明:封顶情况下,随着定植密度的减少,叶绿素含量增加,叶片净光合速率增加。定植密度相同,封顶越早,叶绿素含量越高,净光合速率增加的越快。低封顶、高密度栽培对温室番茄产量的影响较大,在一定范围内栽培密度增加,留果盘数相应减少可增加温室番茄产量。低封顶有利于温室番茄品质的提高。The experiment studied the effect of controlling different growing point on photosynthesis,production and fruit quality of tomato in greenhouse,by controlling different densities.The resulted showed that with the reduction in planting density,chlorophyll content and leaf net photosynthetic rate are increased in the case of the same topping position.The lower topping position,the higher chlorophyll content,the faster net photosynthetic rate increased in the case of the same planting density.Low growing point and high-density planting have a larger effect for tomato production in sunlight greenhouse.Planting density increased with a corresponding reduction in the number of remaining fruit can increase the tomato production in greenhouse.It is not significant for fruit quality of greenhouse.
