不同遮荫条件对龙蒿生物学产量的影响

Effect on Artemisia dracunculusbiology Yield by Different Shading Condition

为了深入了解光照对野生蔬菜龙蒿的生物学产量的影响,通过设置不同的遮荫条件对其进行了研究。结果表明:透光率50%时,龙蒿生物学特征优于对照(透光率100%),随着透光率的减小,生长量明显减少,说明适当遮荫有利于龙蒿生物学产量的提高,但过度遮荫则明显抑制龙蒿的生长发育。

In order to comprehend the effect of light on the biomass of Artemisia dracunculus deeply, the study under the different shading conditions was conducted. The results showed that when the light transmittance was 50%, the biological trait was prior than thoes of the CK （light transmittance was 100%）. With the light transmittance decreasing,the biomass decreased obviously. That was to say,the proper light transmittance was propitious to the increasing of biomass, while in excess of overshadow,the growth and develop was restrained evidently.
