利用城市污泥生产的有机-无机复混肥肥效试验

Fertilizer Efficiency Experiment of Organic-inorganic Compound Fertilizer by Using Municipal Sewage Sludge

通过大田试验,初步探讨了污泥有机-无机复混肥在青海东部春油菜上的施用效果。结果表明,施用污泥有机-无机复混肥后,春油菜产量有显著增加,春油菜农艺性状的各项指标均有提高。由此说明,在青海省大面积推广污泥有机-无机复混肥是可行的。

Through field experiment, the application effect of municipal sewage sludge organic-inorganic compound fertilizer on using spring oilseed rape in eastern Qinghai was preliminarily studied. The results showed that the yield of spring oilseed rape had a significant increase, and all index of agronomic traits in spring oilseed rape were improved. This results showed that it was feasible to widespread extend the organ- ic-inorganic compound fertilizer in Qinghai Province.
