摘要: 多花苀子梢在岷江上游干旱河谷区广为分布，资源丰富。多生于山坡及向阳地、石质山地、干燥地及溪边的灌丛中，其伴生植物多以豆科、蔷薇科为主。在该区域针对多花苀子梢的研究较少。对多花苀子梢人工繁育进行了研究，以期将多花苀子梢作为抗旱物种或景观植物进行推广。多花苀子梢可用种子点播和嫩枝扦插两种方式进行繁殖，其中种子采用浸种催芽法进行预先处理，在60℃水温浸种处理方式下，种子发芽率达到最高82.65%，种子催芽后，在田间进行点播，在良好的田间管理措施之下，多花苀子梢植株当年生长量可达90cm以上，且当年可开花1次；多花苀子梢一般选用嫩枝进行扦插繁殖，在使用生根剂的处理下，可大大提高插穗条生根率，其中以200 mg·kg^-1浓度为最高，生根率达84.33%。多花苀子梢在岷江上游干旱河谷区分布较广，采种较为容易，用种子点播萌发实生苗抗逆性强，育苗成本低于嫩枝扦插繁殖，因此在大量育苗时可优先考虑种子繁殖的方式。

Abstract: Campylotropis polyantha plants are rich in resources in the dry valley area of the upper reaches of the Minjiang River, and most of them are found in the shrubs of rocky mountains, dry land and streams along the hillsides and sunny places. The Associated plants are mainly leguminous and Rosaceae. There were few studies of the Campylotropis polyantha in this area, hence researches were made on the artificial breeding of the Campylotropis polyantha in order to promote the flowering scorpion shoots as drought-resistant species or landscape plants.It could be propagated by seed they were dibbled and twig cutting. The seeds were pretreated by soaking and germination method, and the seed germination rate reached 82.65% at 60℃ water temperature soaking treatment. After seed germination, in the field, under good field management measures, the growth of the flowering scorpion shoots could reach more than 90 cm in that year, and they could bloom once in the same year. Campylotropis polyantha was generally selected by cutting shoots. Under the treatment of the root-promoting reagent solution, the rooting rate of the cuttings could be greatly improved, with the highest concentration of 200 mg·kg^-1 and the rooting rate of 84.33%. The resources of Campylotropis polyantha in the arid valley of the upper reaches of the Minjiang River are widely distributed, and the seed collection is relatively easy. The seedlings germinated with seeds have strong stress resistance, and the cost of seedlings is lower than that of shoots. Therefore,the priority can be given to the seed propagation method when a large number of seedlings are bred.
