以青梗菜为试材,通过对青梗菜农艺性状和产量测定,探究大量元素水溶肥中添加γ-PGA、GABA及其复配产物对青梗菜生长的影响。结果表明,在大量元素水溶肥中添加γ-PGA、GABA及其复配增效物质时,均能促进青梗菜的农艺性状和产量,以添加量为0.2‰γ-PGA和1‰GABA时,促生效果最好,其与对照相比,SPAD值提高9.60%,叶片数增加13.59%,最大叶面积增加33.43%,单株质量增加15.05%。为后期在新型肥料的推广应用中提供参考依据。
In order to understand the effects of the addition of the γ-PGA and GABA on growth of green cabbage were studied in water soluble fertilizer. Through the determination of agronomic characters and yield. The results showed that water soluble fertilizer adding γ-PGA, GABA and compound substance can promote the agronomic characters and yield of green cabbage. The best growth promotion effect was found when the amount of γ-PGA was 0.2‰ and GABA was 1‰. Compared with the control, SPAD increased by 9.60% , leaf number increased by 13.59%, the largest leaf area increased by 33.43%, weight per plant increased by 15.05%. This study provides a reference for the promotion and application of fertilizer in the future.
