摘要
经过盆钵试验研究,无论施入有机肥、尿素,还是有机肥配施尿素均能使油菜的硝酸盐累积,且高氮水平各处理油菜的硝酸盐积累量均高于低氮水平各处理。与施用尿素比较,施用有机肥有利于控制油菜的硝酸盐累积;但增加有机肥的施用量,油菜硝酸盐累积也有加重的趋势。
Through pot experiment, the results showed that the nitrate accumulation in rape increased if Nitrogen fertilizer(N), Organic Manure(OM), or OM&N fertilizer was supplied. And compared to Urea, OM was better in the control over rape’s nitrate accumulation. Rape’s nitrate accumulation increased with fertilization increasing, including OM.
