基于正交试验的小白菜“黄玫瑰”产量和品质影响因素分析

Analysis on Factors Influencing Yield and Quality of Chinese Cabbage “Yellow Rose” Based on Orthogonal Experiment

为了探明种植密度、复合肥施用和寡糖喷施对小白菜生长发育、产量和维生素C含量的影响,为小白菜的种植生产提供依据。采用3因素3水平的L9(3^4)正交设计试验,开展田间种植,结果表明对小白菜叶片数、叶柄宽、根系发育、植株重量和产量起主要作用的因素是复合肥;对株高和维生素C含量起主要作用的因素是密度;对茎叶比起主要作用的因素是寡糖喷施。

The study aimed find out the effects of planting density,compound fertilizer application and oligosaccharide spraying on the growth,yield and vitamin C content of Chinese cabbage,to provide a basis for the cultivation of Chinese cabbage.Using three-factor and three-level L9(3^4)positive design experiment and field planting,the result showed that the main factor affecting the number of leaves,leaf buffing,root development,plant weight and yield of Chinese cabbage was compound fertilizer;the main factor affecting plant height and vitamin C content was density;the main factor affecting stems and leaves was oligosaccharide spraying.
