摘要
Abstract
[Objective] The study aimed to discuss the law of the effect of applying EDTA in the cadmium-polluted field on the growth of rice.[Method] With the rice variety Xiushui 63 with high cadmium accumulation and the conventional variety ⅡYou 527 as the tested materials, 2.0 mmol/ L EDTA was applied on the potted soil to study the effect of EDTA added in the cadmium-polluted soil on the growth of rice with different cadmium enrichment types.[Result] Applying EDTA in the cadmium-polluted soil could increase the plant height and reduce the root length of rice.The effects of EDTA applied in the soil with high cadmium (5.0 mg/kg) pollution on the rice growth were better than that with low cadmium(1.0 mg/kg) pollution on the rice growth.The effects of cadmium pollution on effective panicle number of Ⅱ You 527 were more significant than that of Xiushui 63.Applying EDTA could increase the effective panicle number, the panicle setting rate, the spikelet number per panicle and 1 000-grain weight of Ⅱ You 527 and reduce the panicle length of cadmium-polluted rice and 1 000-grain weight of Xiushui 63.Under the same condition, the effective panicle number and panicle setting rate of Ⅱ You 527 were superior than that of Xiushui 63.[Conclusion] This research provided the sciensific basis for controlling the cadmium absorption by rice with the improving measures.关键词
