施肥对雷公藤叶内酯醇含量的影响

The Effect of Fertilization on Triptolide Content Change in Tripterygium wilfordii Leaves

  • 摘要: 通过二次通用旋转组合设计建立雷公藤叶内酯醇含量与氮磷钾施肥量的3因子回归方程。结果表明:影响雷公藤叶内酯醇含量的顺序为:N>P>K,N肥对于提高雷公藤叶内酯醇含量的作用较大;应用计算机模拟试验,雷公藤叶内酯醇含量大于8871mg/kg的优化组合为,尿素663~864kg/hm2,过磷酸钙939~1191kg/hm2,硫酸钾1240~1641kg/hm2,可得叶内酯醇含量为90462~110541mg/kg,是对照内酯醇含量的42~51倍。

     

    Abstract: The regressional equation to reflect the correlations among fertilization quantities of nitrogen(N), phosphorus(P) and potassium(K) fertilizer and the triptolide contents in the Tripterygium wilfordii leaves was designed with common quadratic regression rotation combination method. The results showed that the effect of the three major elements on the leaf triptolide content was ordered as N>P>K, indicating the effect of nitrogen fertilizer made the relatively greater contribution to the increment of triptolide content in the leaves. Taking triptolide content in the leaves to be more than 88.71mg/kg as the agronomic objective, the optimal fertilization combination obtained by computer simulation was: 66.3~86.4 kg/hm2 of urea, 93.9~119.1 kg/hm2 of calcium superphosphate and 124.0~164.1 kg/hm2 of potassium sulfate. The highest triptolide content in the leaf samples of T. wilfordii reached 90.462~110.541mg/kg, which was 4.2~5.1 times of the triptolide content of the control.
