摘要: 为了研究磷胁迫对三七生长及干物质积累的影响,确定适宜的施磷量。笔者采用盆栽土培试验,定期采样测定植株生长性状及干重。结果表明,缺磷抑制1年生三七及2年生三七生长及其干物质积累;高磷利于1年生三七生长及干物质积累,对2年生三七生长及干物质积累有抑制作用。1年生三七的适宜施磷量为0.18 g/kg土,2年生三七的适宜施磷量为0.15 g/kg土。

Abstract: In order to study the effect of phosphorus stress on growth and dry matter accumulation of Panax notoginseng, and explore suitable P amount, the authors adopted pot culture experiment to measure the growth traits and dry weight of Panax notoginseng by collecting samples in fixed time. The results showed that: phosphorus deficiency inhibited plant growth and dry matter accumulation of 1-year-old and 2-year-old of Panax notoginseng; high phosphorus condition was good for plant growth and dry matter accumulation of 1-year-old of Panax notoginseng, while inhibited 2-year-old of Panax notoginseng. The suitable P2O5 amount for 1-year-old and 2-year-old of Panax notoginseng was 0.18 g/kg, 0.15 g/kg in soil, respectively.
