对城市垃圾经高温高压水解处理后,发酵腐熟而成的垃圾肥的养分质量状况及其对盆栽小白菜植株体内养分及土壤农化性状的影响进行了研究,结果发现,此种垃圾处理技术生产的有机肥能使小白菜植株体内氮磷钾含量都有一定的增加,其中氮含量增加最为明显,同时还可以提高小白菜植株体内钙、镁、硼、铁等微量营养元素的含量;土壤有机质和养分供应力等也相应提高,酸性土壤pH值增加,土壤趋向中性。
After the municipal solid waste was hydrolyzed by high temperature and high pressure, the nutrient status of the garbage composted by fermentation and its effect on the nutrient and soil agronomical characters of the plants in potted cabbage were studied. The results showed that the production of such waste treatment technology Organic manure could increase the contents of nitrogen, phosphorus and potassium in cabbage plants, and the nitrogen content increased most obviously. At the same time, the content of trace nutrients such as calcium, magnesium, boron and iron in cabbage plants could also be increased. The contents of soil organic matter And nutrients supply also increased accordingly, pH of acidic soil increased, soil tended to be neutral.
