摘  要：
为了解堆肥施入重金属Cu、Cd污染土壤后对蔬菜品质和产量的影响,利用盆栽试验研究了不同堆肥用量下茼蒿品质、产量和重金属含量的变化。结果表明,随着堆肥用量的增加,茼蒿产量、粗蛋白、Vc、P和K含量先显著增加后降低,而茼蒿可溶性糖含量呈先显著降低后增加的趋势。堆肥量的增加显著降低茼蒿中Cu含量,比对照最多降低35.5%。茼蒿地上部Cd、根部Cu和Cd含量呈先显著降低又上升的趋势。茼蒿地上部Cd含量在堆肥用量为20g·kg-1时达最低,根部Cu、Cd含量与对照相比最多分别降低20.1%和39.5%。对于污染地区的茼蒿种植,试验堆肥的适量施用是切实可行的。

摘  要：
The experiment was designed to investigate the effects of chicken dung compost on the quality and production of chrysanthemum grown in heavy metal contaminated soil. We studied the change of quality,production and content of heavy metals of chrysanthemum for applying different compost amounts of 0,20,40,60,80,100 g·kg-1. The results showed that with increase of compost amount,the production,crude protein,Vc and total content of P and K of chrysanthemum increased first and decreased afterward significantly,while reversely for the content of soluble sugar of chrysanthemum. The content of Cu in chrysanthemum was significantly reduced by 35.5% compared with that of the control due to the increase of compost amount. Moreover,the content of Cd in over-ground part of chrysanthemum and Cu,Cd in its root showed a trend of significant decrease at first and then increase. The content of Cd in chrysanthemum' over ground part reached the lowest at the amount of 20 g·kg-1 compost applied. Compared with the control,the content of Cu,Cd in chrysanthemum root decreased at most by 20.1% and 39.5%. As a result,adequate compost is feasible to be applied in such kind of heavy metal contaminated areas where chrysanthemum would be grown in. Notwithstanding,it's subjected to further research for the applied compost amount in terms of different types of crops and soil.
