摘要:

摘 要:【研究目的】本实验目的是详细了解甘肃省岷县当归的生长发育特性,为以后培育优良品种研究提供数据支持和科学基础。【方法】选定野外试验田,固定样方,采用人工播种及育苗移栽的种植技术,同时对不同生长期当归进行观测记录。【结果】通过对当归不同生长期进行动态调查,得出当归最适宜采收期是第二年的9月,种子适宜采收期是第三年的8月下旬。当归根每平方米的鲜重产量约是882 g,而干重为252g,折干率约为3.5,每公顷当归蕴藏量是2520 kg。【结论】岷县当归适宜采用育苗移栽的栽培方法,但荒地育苗造成资源环境恶化,移栽苗的冬季贮藏易引起早期抽薹,因此,急需注重新当归育苗技术,加强优良品种选育。

Abstract:

【OBJECTIVE】The study aimed to learn more about the growth characteristics of Angelica sinensis (Oliv.) Diels. and supply research data and scientific bases for improving good breeding in Gansu region. 【METHOD】Selecting experimental field flot, artificial seeding ,transplanting cultivation, observing and recording the different growth stages were used.【RESULTS】By dynamic investigation of different growth stages of Angelica sinensis (Oliv.) Diels.,the best harvest time of the root was in September of the second year, the suitable time to harvest seeds was in August of the third year. The fresh weight of the roots were about 882 g for each square meter,the dry weight of the roots were about 252g for each square meter,the drying rate was 3.5.The dry weight of the roots were 2520 kg for each hectare.【CONCLUSION】The seedling transplanting cultivation is suitable for Angelica sinensis (Oliv.) Diels. in Gansu region, but wasteland resources and environmental degradation caused by breeding, the winter storage of transplanting seedlings is easy to early bolting. Therefore,we must pay attention to the new technology of growing seedlings and strengthen improving good breeding.
