城市污泥、垃圾复混肥对油菜产量及土壤肥力性状的影响

利用盆栽试验,研究了不同配方城市生活垃圾和污泥研制的粒状有机无机复混肥料对油菜产量、品质以及对土壤肥力性状的影响,结果表明:施用污泥和垃圾复混肥料后,油菜产量、叶绿素含量,土壤有机质含量都有明显提高,其中以复混肥W1和L1的肥效最好,均达显著水平。土壤中铜含量高于对照,达显著水平,但在安全范围之内;镉、铅差异不显著。这与垃圾、污泥本身有机质含量较高和试材中铜含量高相符合。施用污泥、垃圾复混肥可显著提高油菜的产量,提高土壤肥力,合理施用不会造成土壤或产品污染。

Effects of Municipal Household Garbage and Sewage Sludge Compound Fertilizer on the Rape Output and Soil Fertility Character

The output and quality of rape and oil fertility characters were studied in pot experiment with granular organic/inorganic fertilizer made from municipal household garbage and sewage sludge in various formula,the results indicated: The employment garbage and sewage sludge compound fertilizer to the rape output, the chlorophyll content, the soil ulmincontent has the remarkable enhanced, and the effect of compound fertilizer W 1 and the L 1 is the best showing the remarkable level; In the soil the heavy metal copper content is higher than the control,at a remarkable level but in the product the content conformed to the national food health standard; The difference between cadmium and lead is not remarkable.This is tally with garbage, the sludge itself organic content high and the material the copper content. The employment of sludge, garbage compound fertilizer may remarkably enhance the rape the output and improve soil fertility.Reasonable employment will not bring the soil or the product pollution.
