不同海拔高度对三七的生长影响很大,随海拔高度的降低,植株也变得矮小,结果亦较少,在南宁就不能结出鲜红的果子。据多年来的观察,海拔越低,发病越早,病害越严重,尤其在高温高湿季节,炭疽病最为严重,如种植在120米,三七的死亡数可达50%以上,在海拔300—500米,死亡数仅在20—30%之间。此外,三七产量和加工率,也随着海拔降低而相对减少。因此,栽培三七最好选择在海拔700米以上,冬季 Different altitudes have a great influence on the growth of Panax notoginseng. With the decreasing of altitude, the plants also become short and the results are few, so bright red fruits can not be produced in Nanning. According to the observation over the years, the lower the altitude, the morbidity is earlier and the disease is more serious. Especially in the high temperature and high humidity season, anthrax is the most serious one. If planted at 120 meters, the number of deaths of Panax notoginseng reaches more than 50% -500 meters, the death toll is only between 20-30%. In addition, the yield and processing rate of Panax notoginseng also decreased as the altitude decreased. Therefore, the best choice for cultivation of Panax notoginseng at an altitude of 700 meters above the winter
