采用土壤盆栽试验研究水溶性有机肥料对水稻抗氧化酶活性及镉吸收的影响。结果表明:施用水溶性有机肥料可提高稻谷产量,显著降低水稻孕穗期叶片超氧化物歧化酶(SOD)、灌浆期超氧化物歧化酶(SOD)和过氧化物酶(POD)活性;降低稻米镉含量,降低率为2.9%~21.5%,提高稻草镉含量,提高率为26.8%~99.1%。以750倍稀释液喷施增产幅度最大,达43.1%,基施(0.16 mL· kg~(-1))配合喷施(750倍稀释液)处理稻米降镉率最高。

A pot experiment was conducted to study the effects of water-soluble organic fertilizer on antioxidant enzyme activities in flag leaves and the absorption of cadmium（Cd）in rice grain and straw. The results showed that the yield of rice grain was increased, and the ac-tivity of SOD at the early booting stage（BBCH 41）and SOD, POD at the early milk stage（BBCH 73）were decreased significantly after ap-plying water-soluble organic fertilizer. The Cd concentration in rice grain reduced by 2.9%~21.5%, while the Cd concentration in straw en-hanced...
