摘要
通过盆栽试验探究染料副产品作为肥料对油菜生长的影响,结果表明:在等氮量情况下,施用染料副产品与硫酸铵在油菜的生物量、叶面积、株高、根长和叶绿素含量等方面没有显著差异,都高于空白对照处理。基施条件下,施用硫铵和染料副产品较空白对照产量分别增加3.25倍和2.73倍;喷施条件下,施用硫铵和染料副产品较空白对照产量分别增加97.1%和76.5%;施用染料副产品还可以增加土壤有机质含量,提高土壤中其它养分含量。
A plot experiment was conducted to study the effects of dye by-products（BP） as fertilizer on rape growth.Under the condition of equal nitrogen amount,the application of BP had similar effects on biomass,leaf area,plant height,root length and chlorophyll content of rape compared with ammonium sulfate,and all were higher compared with no fertilization.The application of ammonium sulfate and BP increased the rape yield by 3.25 and 2.73 times as basic fertilizer,while 97.1% and 76.5% as foliar fertilizer,respectively.The application of BP also could improve the contents of organic matter and other nutrients in soil.
