摘　　要：本试验以不同浓度的营养液 (B)对两个网纹甜瓜品种 (A)的植株生长情况及产量、品质的影响进行了初步研究。结果表明 :温室基质栽培条件下 ,在甜瓜不同的生长时期应施以不同的营养液浓度 ,幼苗期至抽蔓期 ,营养液EC =1.5～ 1.9比较合适 ;座果期至果实成熟期 ,营养液EC =2 .3～ 2 .7比较合适。不同的甜瓜品种对营养液浓度的要求不尽相同。本试验中 ,AG15甜瓜品种对营养液浓度的适应性好于AG5,AG15品种的最高产量比AG5高 4 50 0kg/h 左右 ,商品瓜率AG15比AG5高出 11%左右 ,最高维生素C含量AG15比AG5高 1.0mg/ g(FW )左右 ,可溶性固形物AG5比AG15高 0 .7。Nutrition solution of two concentrations were applied to two muskmelon varieties to study their growth,output and quality.The results showed that concentrations of nutrition solution were vary with the stages melon grouth under media cultivation in greenhouse.A solution with EC value from 1.5 to 1.9 was suitable for seedling stage and shooting up stage,while solution with a higher ECvalue of 2.3 to 2.7 was sufficient for later stages.The results also indicated that melon varieties were differed in the needs of nutritional concentration.Melon variety AG15 in this experiment showed better adaptability to nutrition concentration,with its top yield about4 500Kg/Ha higher than that of AG5,rate of merchantable fruit about 11%higher,top Vc content about 1.0mg/gFW higher,and soluble dry matter 0.7 higher.
