摘要: 为研究不同育苗方式对夏枯草(Prunella vulgaris L.)的影响,比较了传统露地育苗、地膜隔离穴盘育苗、接触土壤穴盘育苗及平盘育苗4种不同育苗方式,分析并探讨了其对夏枯草幼苗形态、农艺性状、生理生化指标的影响及各指标间的关联度。结果表明,4种育苗方式中,2种穴盘育苗方式在根系发育方面表现最优,根长和根系体积分别为传统露地育苗的1.80倍和2.50倍,根系与基质结合紧密,有利于成苗与移栽。在生理代谢方面,2种穴盘育苗显著促进了可溶性糖的积累,其中,地膜隔离穴盘育苗方式的叶片可溶性糖含量为传统露地育苗的1.30倍。3种光合色素总量以传统露地育苗最高[(0.695±0.039)mg/g],2种穴盘育苗方式次之[(0.563±0.042)mg/g、(0.614±0.008)mg/g],平盘育苗方式最低。由此可见,穴盘育苗在促进夏枯草根系构建与糖类积累方面优势明显,适用于标准化种苗生产;传统育苗虽光合色素含量较高,但适于小规模种植;平盘育苗整体生长不良,不推荐在生产中应用。

Abstract: To investigate the effects of different seedling raising methods on Prunella vulgaris L., four methods were compared: Traditional open-field seedling raising, plug seedling raising with plastic film isolation, plug seedling raising with direct soil contact, and flat tray seedling raising. The influences of these methods on seedling morphology, agronomic traits, and physiological and biochemical indicators of Prunella vulgaris, as well as the correlations among these indicators, were analyzed and discussed. The results showed that among the four seedling raising methods, the two plug seedling raising methods exhibited the best root development. Their root length and root volume were 1.80 times and 2.50 times those of traditional open-field seedling raising, respectively. The roots were closely bound to the substrate, which was conducive to seedling establishment and transplanting. In terms of physiological metabolism, the two plug seedling raising methods significantly promoted the accumulation of soluble sugars. Specifically, the leaf soluble sugar content under plug seedling raising with plastic film isolation was 1.30 times that of traditional open-field seedling raising. The total content of the three photosynthetic pigments was the highest in traditional open-field seedling raising [(0.695±0.039) mg/g], followed by the two plug seedling raising methods [(0.563±0.042) mg/g and (0.614±0.008) mg/g], and was the lowest in flat tray seedling raising. It could be concluded that plug seedling raising had obvious advantages in promoting root system construction and carbohydrate accumulation in Prunella vulgaris, and was suitable for standardized seedling production. Although traditional seedling raising had a higher photosynthetic pigment content, it was only suitable for small-scale cultivation. Flat tray seedling raising resulted in poor overall growth and was therefore not recommended for production applications.
