摘要
试验以＂金妃＂甜瓜为材料,采用基质培养方法,通过测定甜瓜果实可溶性固形物、可溶性糖、Vc、可溶性蛋白、总酸含量等营养品质指标变化规律,研究了不同磷素用量对甜瓜营养品质形成的作用效应。结果表明：适宜的磷素用量（即0.9～1.2mmol·L^-1）时,不仅可以改善甜瓜可溶性固形物、可溶性糖、Vc、可溶性蛋白、总酸含量等营养品质,而且也提高了产量;而当磷素用量低于0.6mmol·L^-1或高于1.5mmol·L^-1时,各项指标均显著下降。
In the experiment,muskmelon（Jinfei）was used as experimental material,adopted the way of sub-strate culture to study the action effects of different dosages of phosphorus element on the quality of musk-melon through measuring change laws of fruit soluble solids,soluble sugar,Vc,soluble protein and total ac-id content.The results showed that appropriate dosage of phosphorus element（0.9～1.2mmol·L^-1）can best pro-mote fruit growth of muskmelon through enhancing chlorophyll content and nitrate nitrogen content whichcan improve nutrient quality of muskmelon which included soluble solids,soluble sugar,Vc,soluble proteinand total acid content,at the same time, yield was increased;While phosphorus dosage was less than0.6mmol·L^-1 or higher than 1.5mmol·L^-1,all indexes decreased significantly.
