重金属锌污染土地大麻种植试验

Cannabis sativa Cultivation Experiments on Heavy Metal Zinc Contaminated Land

[目的]研究在重金属锌污染的土地上能否进行大麻种植。[方法]采用尺量法、称重法和抽样法,测定大麻的株高、1/2杆杆直径,分杆和枝叶称量鲜重,以及土壤和大麻中铅、锌含量指标。[结果]所选土壤受到重金属锌的轻度污染,大麻中铅、锌含量超标,而铜含量正常。两块地的大麻株高有明显差异,但1/2高度处的直径、产量以及雌雄差异比较,都无显著性差异。[结论]该研究可以为进一步利用多种指标研究重金属锌污染土地上大麻种植试验提供参考。

[Objective] The research aimed to study whether Cannabis sativa can be cultivated on heavy metal zinc contaminated land.[Method] The taping method,weighing method and sampling method were used to determine the height,1/2 of rod diameter,the fresh weight of sub-par and foliage of the Cannabis sativa,as well as indicators of lead,zinc content in soil and Cannabis sativa.[Result] The selected soil lightly polluted by heavy metals zinc,the lead,zinc content exceeded and copper content normal in the Cannabis sativa.The height of Cannabis sativa was significant difference on two places,but 1/2 of rod diameter production as well as differences comparison of male and female had no significant difference.[Conclusion] The research could provide the reference for the further study for the experiments of Cannabis sativa cultivation on heavy metal zinc contaminated land using various indicators.
