怀牛膝(Achyranthes bidentata Biume)属苋科的多年生草本植物,其根部可供药用,为医药上常用的强壮滋补药。产地原以我国河南省为主,近年来江浙一带也广泛引种栽培。怀牛膝的产量虽逐年增长,可是仍未能满足医药事业日益发展的需要,而且各地的产量指标相差悬殊。所以提高单位面积的产量,寻找高产关键,就成为药用植物栽培上迫切需要解决的问题之一。近年来,生长刺激素开始在药用植物栽培的领域中进行了研究与应用,根据很多研究资料,说明了应用植物生长刺激素,能促进种子发芽,茎叶生长等作用,并对提高产量与质量 Achyranthes bidentata Biume is a perennial herb of the family Polygonaceae. Its root can be used medicinally and is a powerful tonic that is commonly used in medicine. The original origin was mainly in Henan Province, China. In recent years, Jiangsu and Zhejiang provinces were also widely introduced and cultivated. Although the output of Achyranthes bidentata grows year by year, it still fails to meet the growing needs of the pharmaceutical industry, and there are wide disparities in production indicators across the country. Therefore, increasing the output per unit area and finding the key to high yields has become one of the urgent problems to be solved in the cultivation of medicinal plants. In recent years, growth stimulating hormones have been researched and applied in the field of medicinal plant cultivation. According to many research data, it has been demonstrated that the application of plant growth stimulating hormone can promote the germination of seeds, the growth of stems and leaves, and increase the yield. quality
