摘要
以C_2H_4、CO_2和N_2为试验因子,选用L_9(3~4)正交设计不同浓度混配组合;以下胚轴长、下胚轴粗和主根长为绿豆芽外观形态考察指标;全株质量和产出比为产量构成考察指标,采用正交设计矩阵分析,对3个外观形态和2个产量构成考察指标的权矩阵分析和外观形态与产量构成的总权矩阵进行分析,为绿豆芽工厂化生产提供最佳混合气调方案。结果表明:影响绿豆芽外观形态和产量构成的权重由大到小的因子与水平依次为A_3=0.230 0、B_1=0.059 7、C_3=0.058 8,说明绿豆芽外观形态和产量构成与C_2H_4、CO_2和N_2的关联度依次为C_2H_4>CO_2>N_2;最优处理组合为A_3B_1C_3。综合分析成本及环境考量,认为生产实践中采用C_2H_460mL·L^(-1)、CO_2800mL·L^(-1)、N_285%(A_2B_1C_2)混合气调方案,有益于绿豆芽下胚轴增长增粗、抑制主根伸长而提高产品外观商品性、增加豆芽产量。
Length and thickness of hypocotyl and length of taproot were chose as morphology components of mungbean sprout.Weight per plant and output ration were chosen as yield components.The atmosphere conditions which contain the concentration of CO2,C2H4 and N2were analyzed by using orthogonal matrix L9（3^4）to study the effects on morphology and yield components.To provide best atmosphere conditions for factory production of mungbean sprouts.The results showed that,the order of factors and level which weighted from big to small was A3=0.230 0,B1=0.059 7,C3=0.058 8,which meant the relevance between atmosphere conditions,morphology and yield components was C2H4〉CO2〉N2.However,based on environment and cost consideration,this research suggested the best atmosphere conditions were C2H460mL·L^-1;CO2800mL·L^-1;N285%（A2B1C2）.
