■缬草,一种高大的草本植物,传统上在中国和俄罗斯都被用作草药。
■这项研究旨在探索如何培育高质量的幼苗,考虑到播种时间等因素,播种密度,阴影,和塑料薄膜覆盖。此外,我们研究了打顶和肥料对V.amurensis生长和品质的影响。
■根据种子发芽的百分比,4月下旬至5月中旬,采用地膜覆盖法,以0.88gm-2的密度播种。最佳移植时间确定为9月下旬,确保98%的高存活率。一般来说,在果实后期(自由基叶数为21.87)和枯萎期(芽数为6.50,根数为234.81),最高显示出生长指数改善最大。打顶提高了戊酸盐的产量(每株植物10.91毫克),枯萎期的戊酸盐(每株植物809.51毫克)和精油(每株植物395.64毫克)。氮肥最大程度地促进了根系的生长,并增加了V.amurensis的生物量。同时,在三种类型的肥料中,氮肥显着提高了戊酸酯的产量至每株植物10.46mg,并提高了戊酸酯的产量至每株植物772.32mg。根据合理的播种因素和移栽时间获得幼苗。打顶和氮肥成为提高这种有价值植物生长和药用品质的优越策略。
■这项研究为栽培V.amurensis提供了可行的见解。
UNASSIGNED: Valeriana amurensis, a tall herbaceous plant, has been traditionally utilized as a herbal remedy both in
China and Russia.
UNASSIGNED: This study was set to explore how to cultivate high quality seedlings, considering factors such as seedling time, seeding density, shading, and plastic film mulching. In addition, we investigated the impact of topping and fertilizer on the growth and quality of V. amurensis.
UNASSIGNED: According to the percentage of seed germination, the seeds of V. amurensis were sowed with 0.88 g m-2 density using plastic film mulching from late April to mid-May (germination percentage was more than 30%). The optimal Transplanting time was identified as late September, ensuring a high survival rate of 98%. Generally, topping showed the most improved growth indices in late fruit period (21.87 for number of radical leaves) and withering period (6.50 for number of buds and 234.81 for number of roots). Topping increased the yields of valtrate (10.91 mg per plant),
valepotriates (809.51 mg per plant) and essential oil (395.64 mg per plant) in withering period. Nitrogen fertilizer promoted maximum root growth and increased the biomass of V. amurensis. Meanwhile, N fertilizer significantly increased the yields of valtrate to 10.46 mg per plant and
valepotriates to 772.32 mg per plant among three types of fertilizers. Seedlings are obtained according to rational sowing factors and transplanting time. Topping and nitrogen fertilization emerge as superior strategies to enhance the growth and medicinal quality of this valuable plant.
UNASSIGNED: This study provides actionable insights for the cultivation V. amurensis.
