摘要: 本试验采用3因素2次饱和回归设计方法,对机械化工厂化育苗条件下椰菜菜(Brassica botritis L.)幼苗生长的最佳营养条件进行了研究,建立了花椰菜幼苗生长量及叶面积与育苗营养液中氮磷钾浓度之间的2次回归模式,拟合度较高。利用回归模式分别对育苗前期和后期花椰菜幼苗生长的最佳营养浓度及氮磷钾3要素各自对花椰菜幼苗生长的促进效应进行了分析和探讨。

Abstract: The experiment used a three-factor,quadratic,saturated incomplete factorial regression design to investigate the optimal nutritional conditions for seedlings of Bras-sica botritis L.in an industrialized seedling production plant.A group of regression models,with higher fitting,were established describing the relationship between the fresh weight/leaf area of the seedling and the concentration of NPK nutrient solution.This paper here presents an analysis and discussion,with the use of regression models,on the optimal concentration of the nutritional solution for seedling growth in the early and late periods,and the positive effect of each of the three factors(NPK)o.n seedling growth of Brassica botritis L

Key words: Brassica botritis L, Industrialized seedling production, Nutritional concentration, Optimization
