1.选地.选择腐殖层深厚,土壤肥沃,质地均匀,有灌溉和排水条件的地块作为提纯复壮田。为了保证人参个体生长发育,在技术措施和管理水平上,都要高于生产田,株距要适当扩大,品种之间应保持一定的距离,防止自然杂交,保证种子的纯度。 2.选择种苗。人参播种出苗3年后开始开花结果,4年以后才能采种。为了恢复某品种原来的纯度和种性,必须在该品种的留种田或生产田中,单株选择3年生的参苗。选择标准,要以符合该品种原来典型为主要依据,即选择主根粗而长,发育均匀,支根少,皮色正,芽胞饱满,无病虫危害的 1. Select the site. Select humus deep, fertile soil, uniform texture, irrigation and drainage conditions of the plots as purification and rejuvenation. In order to ensure the individual growth and development of ginseng, the technical measures and management level should be higher than that of the production field. The spacing between plants should be appropriately expanded. The distance between varieties should be kept at a certain distance to prevent the natural hybridization and ensure the purity of the seeds. 2. Select seedlings. Ginseng seedlings planted 3 years after the start of flowering, 4 years after the seed. In order to restore the original purity and species of a certain variety, it is necessary to select the three-year-old ginseng seedlings in the remaining farming or producing fields of the variety. Selection criteria, to be consistent with the original typical of the breed as the main basis, that is, choose the main root thick and long, uniform development, less branching, skin color is positive, full sprouts, no pests and diseases hazards
