摘　　要：为探究花生麸处理对菜心品质和糖分积累的影响,以60天特青菜心为试材,设置花生麸30 kg·667 m^(-2)、40 kg·667 m^(-2)、50 kg·667 m^(-2)和复合肥30 kg·667 m^(-2)以及不施肥(CK)5个处理,研究不同处理对菜心产量、品质及糖代谢相关酶活性的影响。结果表明,50 kg·667 m^(-2)花生麸处理的菜心单株质量比对照提高50.22%,比复合肥处理提高8.19%。花生麸用量达40~50 kg·667 m^(-2)时,菜心薹叶中可溶性糖、还原性糖、蔗糖、果糖和薹茎中维生素C、还原糖、蔗糖含量均显著优于复合肥及对照处理。50 kg·667 m^(-2)处理时,薹叶和薹茎中可溶性糖及蔗糖含量最高,可溶性糖含量(w,后同)为17.09 mg·g^(-1)和29.7 mg·g^(-1),蔗糖含量为0.51 mg·g^(-1)和0.87 mg·g^(-1),与40 kg·667 m^(-2)处理间差异不显著。薹茎中蔗糖和可溶性糖含量与蔗糖合成酶活性呈显著正相关,果糖和还原糖含量与中性转化酶活性和蔗糖磷酸合成酶活性呈显著正相关。从成本与效果综合考虑,以花生麸40 kg·667 m^(-2)处理较适宜。A 60-day Chinese flowering cabbage variety was used to test the effects peanut bran fertilization on quality and sugar accumulation.The experiment had five treatments with peanut bran 30 kg·667 m^(-2),peanut bran 40 kg·667 m^(-2),peanut bran 50 kg·667 m^(-2),compound fertilizer 30 kg·667 m^(-2),and no fertilizer as CK.The results showed that use of peanut bran at the rate of 50 kg·667 m^(-2) significantly increased the plant weight of Chinese flowering cabbage,50.22%higher than that of no fertilization and 8.19%higher than that of compound fertilizer.Whenpeanut bran use at rate of 40-50 kg·667m^(-2),the contents of soluble sugar,reducing sugar,sucrose,fructose in the leaves and the contents of vitamin C,reducing sugar,sucrose in the stem were significantly greater than those in the compound fertilizer and the control.At the application rate of peanut bran 50 kg·667 m^(-2),the contents of soluble sugar and sucrose were the highest,the soluble sugar contents were 17.09 mg·g^(-1) and 29.7 mg·g^(-1),and the sucrose was 0.51 mg·g^(-1) and 0.87 mg·g^(-1) in the leaves and stems,respectively.No difference was observed between the rate of 50 kg·667 m^(-2) and 40 kg·667 m^(-2).The contents of sucrose and soluble sugar in stem were positively correlated with sucrose synthase activity,and the fructose and reducing sugar contents were positively correlated with neutral invertase and sucrose phosphate synthase activities.Considering the treatment cost and effect,the application of peanut bran 40 kg·667 m^(-2) gave the best result.
