不同土壤环境对温郁金栽培的影响研究

Experimentation of Curcuma wenyujin in different soil conditions

摘要: 试验研究不同土壤环境对温郁金栽培的影响结果表明，在石灰土上栽培的温郁金具有较长的生长期和较高的生物量，莪术中莪术油含量也比栽培在酸性红壤上的高，石灰土比红壤更能忍受施加铵态氮肥带来的负面效应。

Abstract: The effect of different soil conditions on growth of C.wenyujin was studied. Results show that C.wenyujin has longer growth period and higher biomass in lime soil. Naphtha content distilled from rootstalks of C.wenyujin in lime soils is also higher in comparison with those in red soils. Lime soil has a stronger capacity of resisting negative effects owing to NH⁺₄-N fertilizer.
