A Study on the Optimal Parameters of Nutrient Solution for Raising Seedlings of Brassica botritis L .in Industrialized Production

doi:10.3321/j.issn:1000-7091.1988.03.015

Abstract

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
