【摘要】 [目的]研究特效植物营养素对杂交菜心产量及生化品质的影响。[方法]在已经采收后才开始用特效植物营养素(SPNE)喷施杂交菜心植株,比较SPNE在非常规使用时期对杂交菜心产量及生化性状品质的影响。[结果]SPNE使杂交菜心的菜薹比对照发得早,生长快,苔粗、苔长、苔重和叶面积增加因而提高产量,在提高产量的同时使产品生化品质更好,用SPNE处理过的菜薹其蛋白质、维生素C、钙的含量超过对照,尤其是叶绿素和糖的含量比对照增加较多,使产品口感更佳。[结论]说明在杂交菜心采收后才使用SPNE也有一定效果。更多还原

【Abstract】 [Objective] The effects of SPNE on the yield and biochemical quality of flowering Chinese cabbage were investigated in this study. [Method] The special plant nutritional element(SPNE) was sprayed on the flowering Chinese cabbage plants after the beginning of harvesting. The effects of SPNE on the yield traits and biochemical quality traits of flowering Chinese cabbage were investigated in the unconventional using period. [Results] The results showed the flowering stalk of flowering Chinese cabbage developed earlier and grew fasterly for the SPNE treatment;the diameter, length and weight of flowering stalk of SPNE-treated flowering Chinese cabbage were all higher than that of control. The SPNE treatment could not only increase yield, but also bring better biochemical quality. The protein, vitamin C and calcium contents, especially the chlorophyll and sugar contents in the SPNEtreated flowering Chinese cabbage were all higher than that of control, making the SPNE-treated flowering Chinese cabbage taste better. [Conclusion] It was indicated although sprayed after the beginning of harvesting, the SPNE had a certain effect on the flowering Chinese cabbage.更多还原
