摘要
氮肥的过量施入导致了许多环境问题,引起了各个方面的重视。该试验研究了单独施用无机肥和有机肥对温室油菜产量的影响。结果表明:施用尿素和有机肥都可以大幅度提高小油菜的鲜重和干物质重量;施用尿素的处理产量稍高于施用有机肥的处理,但差异不显著。建议在种植保护地绿叶菜时要尽量少施用无机肥料,多施用有机肥,减少生产成本的同时也减少化肥投入带来的环境压力。
Excessive application of N fertilizer could lead to many environmental problems,which have been paid much attention.The results of this paper proved that the urea treatment and organic fertilizer treatment could both promote the yield of Chinese rape,and the yield of urea treatment was little higher than that of organic treatment.So we should add the use of organic fertilizer and decrease the application of inorganic nitrogen fertilizer,which was advantageous to protect the environment and improve the quality of vegetables.
