摘要
采用三因素五水平正交旋转组合设计,用基质盆栽法,研究了氮、磷、钾施用量与辣椒矿物质含量的相关性,建立了相应回归方程。结果表明:氮、磷、钾施用量对辣椒果实的全氮、全磷、全钾含量影响显著,施肥水平越高,辣椒果实中积累的全氮、全磷、全钾越多。说明施用氮磷钾能有效地促进辣椒果实的生长与发育,有利于辣椒高产优质生产。
By means of orthogonalty rotational combination design, a three-factor(N P K) substrate cultivation experiment was conducted on hot pepper, and the zero level was N:244 mg·L^(-1),P:42 mg·L^(-1), K:313 mg·L^(-1). The regression equations of the relationship between N,P,K and the effects on the total N, total P, total K contents were discussed. The results indicated that the relationship between the total N content and the N applicated is linear, and there is a curve relationship between the total P content and the P applicated, for the total K content, it is curvilinear changed by the K applicated, and influenced by the N, P applicated.
