无土栽培有机肥含量对小型西瓜产量和品质的研究

以小型西瓜京秀为试材，研究了基质无土栽培情况下增施有机肥对西瓜产量和品质的影响。结果表明，基质中增施有机肥对西瓜单瓜重和亩产量有一定影响，对提高西瓜的可溶性固形物、Vc含量、可溶性蛋白质和氨基酸具有显著效果，能显著改善西瓜品质。增施一定量的有机肥能提高西瓜的单瓜重和亩产量，在低水平有显著效果，以每立方米基质增施8kg为好，继续增施效果不明显；在每立方米基质增施15kg发酵鸡粪对可溶性固形物和Vc含量的效果显著，继续增加有机肥含量效果不明显，但是对于边缘可溶性固形物含量有效；基质中有机肥含量越高，可溶性蛋白质和氨基酸含量越高。

Effect of Organic Manure on Yield and Quality of Mini-watermelon under Medium Cultivation

The experiment adopted Jingxiu watermelon as examination material, the effects of organic manure content on yield and quality of fruit in the plant condition of soiUess were studied. The result indicated that the organic manure was benefit for the yield and quality of watermelon fruit, and was attributed to the soluble solids,Vc, soluble protein and dissociative amino add. The organic manure content in low level of 8 kg/m^3 had obvious effects on the weight of single fruit and yield , and in the level of 15 kg/m^3 had obvious effects on soluble solids and Vc, but there was no more effects if the organic manure contem in the soilless plant was improved. To the soluble protein and dissociative amino acid, it showed the more the organic manure content, the more the soluble protein and dissociative amino acid.
