以无限生长型圆串番茄‘洛美’为试材，利用封闭式无土栽培系统，采取日光温室架式无土栽培三穗果打顶促成法，在床距固定（90 cm）的条件下，研究了不同株距（26、21、16、11 cm）对番茄水肥吸收及植株生长、产量和品质的影响。结果表明：番茄对氮、磷、钾及水分的吸收速率随植株生长呈单峰曲线变化，单株吸收总量随栽植密度增大逐渐减少；小区产量以11 cm 株距处理最高，分别比16、21、26 cm 增产4．65％、18．76％和38．84％，但其单果重及单株产量均显著低于其它处理。随栽植密度增大，果实可溶性糖、糖酸比、VC及可溶性固形物含量降低，番茄红素含量则呈先升高后降低趋势。综合分析产量、品质及果实商品性，以90 cm ×16 cm为架式栽培番茄适宜的栽植密度。

The infinite-growth-typed rounded bunchy tomato cultivar‘Luomei’was chosen for exper-iment.Using enclosed soilless cultivation system with fixed frame distance of 90 cm,the effects of different plant spacings (26,21,16 and 11 cm)on water and fertilizer uptake,plant growth,yield and quality of to-mato were studied based on elevated soilless cultivation and 3 -cluster topping method in solar greenhouse. The results showed that,along with the growth of tomato,the uptake amount of N,P,K and water had in-creased firstly and then decreased.The total uptake amount of N,P,K and water per plant decreased gradual-ly along with the increase of planting density.The plot yield was the highest when the plant spacing was 1 1 cm,which increased by 4.65%,18.76%and 38.84%respectively than that of 16,21 and 26 cm treatment. The single fruit weight and yield per plant of 1 1 cm treatment were significantly lower than those of other treat-ments.The soluble sugar,sugar acid ratio,VC and soluble solid contents decreased with the increase of plant-ing density,and the lycopene content increased firstly and then decreased.Comprehensively considering yield,quality and commodity of fruits,90 cm ×16 cm was the desired planting density for elevated cultivation of tomato.
