摘要
采用田间试验方法研究了施用钾肥对甘蓝产量、品质及养分吸收状况的影响,结果表明:在施氮225kg/hm^2、磷90kg/hm^2的基础上,施用钾肥能增加甘蓝产量,增加幅度为13.77％～41.56％,提高可溶性固形物、蛋白质、氨基态氮和Vc含量,促进植株对氮、磷养分的吸收。
The experiment results indicated that potassium fertilizer could increase yield of cabbage by ' 13.77% ~41.56% ,and could also increase content of soluble solid matter,protein,aminoN and Vc. Thus it could improve the quality of cabbage. In addition, potassium could enhance uptake of N and P.
