摘要:

为提高金莲花育苗的幼苗质量,筛选适宜推广应用的金莲花育苗基质配方,探索栽培基质对金莲花幼苗生长影响的生理机制,本试验以金莲花幼苗为植物材料进行盆栽试验,研究了不同比例的草炭、蛭石和珍珠岩改良园土对金莲花幼苗生长、生理和光合特性的影响。结果表明:添加草炭后T4、T5、T7对园土的理化性质有明显改善,其中以处理T7(草炭∶珍珠岩∶蛭石∶园土=1∶1∶1∶1)改善效果最好,金莲花幼苗的株高、冠幅、叶面积、叶片数量分别比对照提高32.08%、26.62%、56.22%、64.41%;显著提高了金莲花叶片的抗氧化酶活性,矿质营养含量,叶绿素含量及光合速率(P<0.05),可作为金莲花育苗的基质配方。

Abstract:

In order to screen suitable substrate formulations and to improve the quality of Trollius chinensis seedlings, and to explore the physiological mechanism of the influence of cultivation substrates on its seedling growth, the pot experiment peat and vermiculite and perlited on the growth, physiology and photosynthetic characteristics of the T. chinensis seedlings were conducted respectively. The results showed that T4, T5 and T7 significantly improved the physical and chemical properties of the garden soil, among which T7 treatment had the best effect on the seedlings. The plant height, width, leaf area and leaves number of the seedlings of T.chinensis increased by 32.08%, 26.62%, 56.22% and 64.41% respectively compared with the control; the antioxidant enzyme activity, mineral nutrient content, chlorophyll content and photosynthetic rate of T. chinensis leaves were significantly increased(P<0.05). Therefore, it could be used as the substrate formula of T. chinensis seedling to replace garden soil.
