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.
