互助县黄芪高产高效栽培技术研究OA

In order to study the high-yield and high-efficiency cultivation techniques of Astragalus membranaceus suitable for promotion and application in Huzhu County,field trials were conducted from four aspects:transplanting time,transplanting density,planting method and seedling type.The results showed that the optimal transplanting time of Astragalus membranaceus in Huzhu County was mid April,the optimal transplanting density was 300 000 plants/hm2,the optimal planting method was transplanting by using black plastic film full covering,and the optimal seedling type was high-quality seedlings with diameter longer than 0.5 cm,length longer than 30 cm,even and smooth root and without branching.By using this cultivation technique,Astragalus membranaceus had high emergence rate,high yield,good quality and good economic benefit.This study could provide a theoretical basis for the large-scale promotion of Astragalus membranaceus cultivation in Huzhu County,and promote the high-quality development of the local traditional Chinese medicine industry.
