改良剂对玉米和大豆间作植株锌铬积累的影响
EFFECTS OF AMENDMENTS ON ACCUMULATION OF ZINC AND CHROMIUM IN INTERCROPPING OF CORN AND SOYBEAN
摘要
Abstract
A pot experiment was conducted to determine effects of different amendments(lime and superphosphate) on accumulation of heavy metals(Zn and Cr) in intercropping of corn and soybean.Results showed that all treatments significantly reduced the contents of available zinc and chromium in soil plants,followed the order of control(CK) low concentration of lime(LI(l)) high concentration of lime(LI(h)),CK high concentration of superphosphate(SP(h)) low concentration of superphosphate(SP(l)),monoculture intercropping.The effect of SP(l) treatment under intercropping condition was the best than all the other treatments with the contents of zinc and chromium in the roots,stems and leaves of corn reduced by 30.72%,35.96%,29.51%,69.98%,64.21% and 51.56%,respectively,compared with the treatment of SP(l) of monoculture corn.Compared with the intercropping corn without any amendments,the contents of zinc and chromium in the roots,stems and leaves of corn were reduced by 55.57%,59.68%,66.57%,64.10%,76.79% and 80.75%,respectively.The contents of zinc and chromium in soybean roots,stems and leaves declined by 0.26%,4.91%,16.42%;14.25%,8.16% and 23.33%,respectively,compared with the treatment of SP(l) of monoculture soybean.They reduced by 63.95%,69.54%,65.49%;54.15%,57.14% and 57.14%,respectively,compared with the intercropping soybean of no amendments.Our results suggest that the SP(l) treatment under intercropping condition could greatly reduce the absorption of zinc and chromium in corn and improve corn yield without increasing the contents of zinc and chromium in soybean.关键词
