Abstract

Objective: To breed a new Astragalus variety and to study its standard cultivation techniques, which are high yield, good quality, disease resistance, anti-reverse with intrinsic quality in line with the standard of the Pharmacopoeia of the People’ s Republic of China.

Methods: By using the method of single plant selection,15 excellent individual plants were selected in 2003→seed period tested in 2004→strains identification tested from 2005 to 2007 → new strains comparison tested for HQZX04-04-01 in medicine period from2008 to 2010→regional tested and production demonstration for HQZX04-04-01 from 2011 to 2014→Longqi 4 was named by Crop Variety Approval Committee of Gansu Province in April,2015.

Results: A new Astragalus variety of Longqi 4( the original code HQZX04-04-01) was bred. By 3 n tests in different ecological zones, the average yield of fresh Astragalus root was 708. 9 kg /666. 7 m2,and was31. 1% increased compared with the control variety; special / first class rate was 21. 5%,30. 6%,in which were 4. 8,5. 3 percentage points higher than that of the control variety, respectively; root rot disease incidence and disease index were 25. 7%,13. 5%,in which were 2. 75,2. 17 percentage points reduced compared with control variety; intrinsic quality were as follows, the total ash was 4. 5%,the extract was 41. 0%,the content of calycosin was 0. 10%,and the content of astragaloside was 0. 076%,respectively,which superior than the 2010 edition of the standard of the Pharmacopoeia of the People’ s Republic of China.

Conclusion: A new Astragalus variety of Longqi 4 is high-yield, good-quality, disease-resistant, anti-inverse and its intrinsic quality in lines with the standard of the Pharmacopoeia of the People’s Republic of China. Longqi 4 is suitable for application at an altitude of 1 900 ~ 2 400 m, the annual average temperature of 5 ~ 8 ℃,semi-arid and cold damp ecological area of annual precipitation of 450 ~ 550 mm.

黄芪新品种龙芪4号的栽培及标准化技术研究

目的:选育一种高产、优质、抗病、抗倒转、内在品质符合《中华人民共和国药典》标准的黄芪新品种，并研究其标准栽培技术。方法:采用单株选育法，2003年筛选出优秀单株15株→2004年种子期试验→2005 - 2007年品系鉴定试验→2008 - 2010年药期HQZX04-04-01新品系比对试验→2011 - 2014年HQZX04-04-01区域试验及生产示范试验→2015年4月龙七四号通过甘肃省作物品种审定委员会命名。结果:选育了黄芪新品种龙芪4号(原牌号HQZX04-04-01)。在不同生态区进行3 n次试验，平均鲜黄芪产量为708根。9公斤/666。7平方米，是31。比对照品种增加1%;特别/头等费率是21。5%, 30。6%，其中4人。8、5。分别比对照品种高3个百分点;根腐病发病率和病害指数均为25。7%, 13岁。5%，其中2人。75年,2。与对照品种相比降低了17个百分点;内在质量如下，总灰分为4。5%，提取物为41。0%，毛蕊异黄酮含量为0。10%，黄芪甲苷含量为0。分别为076%，优于2010年版《中华人民共和国药典》标准。结论:龙芪4号黄芪新品种高产、优质、抗病、抗逆，其内在品质符合《中华人民共和国药典》标准。龙旗4号适宜应用于海拔1 900 ~ 2 400 m，年平均气温5 ~ 8℃，年降水量450 ~ 550 mm的半干旱寒湿生态区。
