紫花苜蓿种植在Cd（II）、Cu（II）、Ni（II）和Zn（II）混合污染的土壤盆栽中，（每种土壤污染浓度为50 mg/kg），光照ph值分别为4.5、5.8和7.1。植物使用适当调整到相同ph值的营养液进行施肥。对照处理的植物在没有重金属混合物的情况下生长。对照植株在3个ph值下的生长基本一致，重金属胁迫植株在3个ph值下也表现出相似的生长行为。差异有统计学意义(P
Alfalfa plants were grown in soil-pots contaminated with a mixture of Cd(II), Cu(II), Ni(II), and Zn(II), (at 50 mg/kg each) Lit pHs of 4.5, 5.8, and 7.1. The plants were fertilized using a nutrient solution, which was adjusted appropriately to the same pH. Plants in the control treatment were grown in the absence of the heavy metals mixture. The growth of the control plants was the same at the three pHs studied and the heavy metal stressed plants also showed similar behavior at each pHs. There were statistically significant differences (P
