硅肥对早稻群体生产力和镉吸收的影响
E ffects of Silicon Fertilizer on Population Production and Cadmium Absorption for Early Rice
摘要
Abstract
Cd (cadmium) pollution in paddy soil is one of most threat to food safety and human health, and it was necessary to find one technology for cadmium reduction in soil and rice. Therefore, one field experiment was set up to research the effects of silicon fer-tilizer on grain yield and cadmium content in rice. The results showed that, appliacation of silicon fertilizer could improve significantly tiller and white root number, and they were increased than CK treatment by 44.5% and 22.6%, the grian yield and filled grains were rised by 11.7% and 5.4%, respectively. However, application of silicon fertilizer could significantly reduced cadmium uptake of rice. Compared with the CK treatment, Cd content of rice in Si fertilization was decreased by 27.6%~32.4%. This indicated that silicon fer-tilizer could not only improve the population quality and the grain yield of rice, but also significantly decline cadmium uptake.关键词
