为了指导知母合理移栽,采用不同移栽密度(行距为30 cm和宽窄行40/20 cm;株距为10 cm、20 cm、30 cm)进行知母栽培,旨在探索适合西陵知母移栽的密度,为知母的规范化栽培提供依据。结果表明,在行距为宽窄行40/20 cm,株距为30 cm时,知母分蘖最少,株高值最小,单株鲜重、根茎鲜重、根茎最大直径和根茎长度均达到最大值,根茎药用活性成分芒果苷和知母皂苷BⅡ的含量也符合2015版药典标准。综合不同移栽密度对知母生长性状和根茎中药用活性成分含量的影响说明,西陵知母最佳种植行距40/20 cm,株距30cm,移栽密度为10.5万株/hm~2。
In order to guide the rational transplanting of Anemarrhena asphodeloides, we planted Anemarrhena asphodelus with different transplanting densities (row spacing 30 cm and width row 40/20 cm; plant spacing 10 cm, 20 cm, 30 cm) Planting density, Zhounimu standardized cultivation provide the basis. The results showed that when the row spacing was 40/20 cm wide and the plant spacing was 30 cm, the number of tillers was the least, the plant height was the smallest, the fresh weight per plant, the fresh weight of rhizome, the maximum diameter of rhizome and the length of rhizome reached the maximum, Pharmacological active ingredients mangiferin and timosaponin B Ⅱ content also meet the 2015 version Pharmacopoeia standards. The effects of different transplanting density on the growth traits of Zhimu and rhizome indicated that the optimal planting distance of Zhiling Zhimu was 40/20 cm with the plant spacing of 30 cm and the transplanting density of 105 000 plants / hm ~ 2.
