摘要
盆栽试验和田间试验结果表明， 施用西湖淤泥可以提高土壤有机质和氮含量， 使土壤阳离子交换量增加， 容重下降， 土壤结构系数提高。蔬菜增产效果明显， 与不施淤泥的对照相比，蔬菜增产４．１％ ～１３．５％ ， 并能提高品质， 蔬菜中维生素Ｃ含量增加， 硝酸盐含量下降。
Results from the pot and field experiments showed that applying sediments of West Lake could increase the content of organic matter and nitrogen in soil,decrease soil bulk density and improve soil CEC and structure coefficient.Vegetable yield was increased by 4.1%-13.5%,as compared with the control and the quality of the vegetable including increase of vitamin C content and decrease of nitrate content was improved.
