通过温室盆栽实验研究了施用羟基磷灰石改良Cd污染土壤对马铃薯生长及品质的影响.实验设置了3个Cd污染水平（0、5、10 mg.kg-1）、6个羟基磷灰石施用量（0、4、8、10、16、30 g.kg-1）和2个马铃薯品种（中薯3号、大西洋）.结果表明,土壤Cd污染导致马铃薯单株产量下降（5 mg.kg-1的Cd污染土壤中降低24%～31%,10 mg.kg-1的Cd污染土壤中降低41%～45%）,但是施用羟基磷灰石可以提高单株产量.相对于不施用羟基磷灰石,5 mg.kg-1的Cd污染土壤中施用10 g.kg-1的羟基磷灰石可以增产17%～39%,10 mg.kg-1的Cd污染土壤中施用30 g.kg-1的羟基磷灰石可以增产45%～58%.由于羟基磷灰石改善了Cd污染土壤环境,因此...

A pot experiment was conducted in a glasshouse to study effects of hydroxyapatite amending Cd polluted soil on growth and quality of potato (Solanum tuberosum L.). In the experiment, 3 levels of Cd pollution (0, 5, and 10 mg x kg(-1)) and 6 levels of hydroxyapatite application (0, 4, 8, 10, 16, and 30 g x kg(-1)) in soil were prepared to plant 2 potato varieties (Zhongshusanhao and Daxiyang in Chinese system). The results showed that Cd pollution in soil resulted in decrease in yield per plant of potato; for example, in the soils with 5 and 10 mg x kg(-1) of Cd, the yield per plant decreased 2...
