施肥对栽培川西獐牙菜生长发育的影响

Influence of Fertilization on Growth and Development of Cultivated Swertia mussotii

以不施肥栽培川西獐牙菜为对照,研究尿素和磷酸二铵对栽培川西獐牙菜生长发育的影响。结果表明,在试验设定施肥量的前提下,尿素可以明显增加栽培川西獐牙菜的株高、分枝数、叶片数、结实率和药材的产量,而磷酸二铵对于产量的增加效果不如尿素明显,但又优于不施肥处理。

Compared with unfertilized Swertia mussotii plant individual, the growth and development of Swertia mussotii plant was studied, which was fertilized respectively with urea and （NH4）2HPO4. The results showed that fertilizing urea dramatically increased the leaves quantity, branch quantity, fructification rate and weight of Swertia mussotii plant individual; however, the effect of fertilizing （NH4）2HPO4 was not so notable.
