Abstract：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.
