摘要/Abstract

摘要： 对塑料大棚栽培的甜椒进行滴灌施肥,研究不同用量的氮磷钾肥料对甜椒品质的影响.结果表明,侧枝是甜椒硝态氮的敏感反应部位,且含量最高.叶片次之,果实最少.高量施肥对甜椒果实的硝态氮与可溶性糖含量没有产生不良影响.果实是甜椒糖分的主要贮存器官,其可溶性总糖含量在50%～55%范围内,高于叶片和侧枝.施肥量减少,果实中肌醇和蔗糖的含量增加.葡萄糖与果糖是甜椒果实主要的可溶性糖类.高量施肥削弱叶片的C素代谢作用,表现为抑制同化物淀粉在叶片的积累.粗淀粉在果实中的含量最高.叶片脂类含量均超过侧枝和果实3～4倍以上,可能是由于叶片中叶绿素含量高所致.

Abstract: In order to study the effect of fertilization on the qualities of sweet pepper(Capsicum annul L)cultured in greenhouse,the experiment was carried out by drop irrigation.The results showed that the most sensitive organ of sweet pepper for nitrate was lateral branch,in which the nitrate content was highest.The nitrate content in leaf was lower than that in lateral branch,and in fruit,the nirtate content was the lowest.High fertilization of N,Pand Khad no negative influence on content of nitrate and total soluble sugars in fruit.The content of soluble sugars in fruit were about 50%～55% under all treatment and higher than that in leaf and lateral branch.Decreasing fertilization would cause increasing of the inosital and sucrose contents.Glucose and fructose were the main soluble sugars in fruit.The metabolism of carbohydrates was weakened by high fertilization,and it experessed as restraining the accumulation of starch content in leaf.The content of starch was the highest in fruit.The lipid content were exceed 3～4 times in the leaf than in the lateral branch and fruit,and perhaps,it was due to the hiher content of chlorophyll in the leaf.
