| 摘 要： | 在被重金属污染的土壤中 ,用Ca(NO3)2 拌种处理甘蓝种子 ,进行甘蓝抗重金属污染试验。结果表明 ,Ca(NO3) 2 拌种可以促进甘蓝种子萌发和幼苗生长 ,增强光合速率和抗逆性 ,使甘蓝叶片中Hg ,Cr,Cd含量分别比对照下降 71.9%～ 97.7% ,2 .77%～ 12 .88% ,38.4 6 %。

Study on Pollution-resistance of Cabbage to Heavy Metal |
| |
| Abstract: | The present paper reports on an anti-heavy metal pollution experiment. In the experiment cabbage seeds are dressed with Ca (NO 3) 2 planted in a heavy-metal polluted field. The experiment proves: cabbage seeds, when dressed with Ca (NO 3) 2, sprout easier and grow better in the field heavily polluted by heavy metals. The experiment also shows that in the cabbage plants the rate of photosynthesis has been greatly increased whereas the contents of Hg, Cr,Cd have been greatly decreased. |
