摘要
对仙客来无土栽培营养液中N、P、K元素采用三因素二次D-饱和最优设计,探讨不同浓度氮磷钾对仙客来生长发育的影响,对仙客来的叶面积、株高、冠幅进行了分析。结果表明:N、P、K最佳浓度组合为300mg/L、60mg/L、325mg/L。
The optimal design of Cyclamen nutrient solution N,P,K elements in a three-factor second D-saturated is adopted. Different concentrations of NPK＇s influence on the Growth of Cyclamen are discussed and cyclamen leaf area, plant height, crown width are analyzed. The results show that： N, P, K optimal concentrations are 300mg/L, 60mg/L, 325mg/L.
