有机 - 无机肥配施增产效应及土壤剖面（NO3）- - N累积定位研究
Effect of Combined Application of Organic Manure and Fertilizers on Crop Yield and Accumulation of NO-3-N in Soil Profile
【摘要】 根据１２年定位研究资料，探讨了不同量有机肥与Ｎ、Ｐ化肥配合施用对粮食产量和０～４００ｃｍ土壤剖面ＮＯ－３－Ｎ累积的影响。结果表明，关中土娄土有机肥与Ｎ、Ｐ化肥配施是该区粮田持续高产的有效措施，同时土体中ＮＯ－３－Ｎ积累少，减少了对地下水污染的可能。
【Abstract】 Effects of combined application of organic manure and chemical fertilizers on crop yield and accumulation of NO-3-N in soil profile were studied according to the results of a 12year located experiment The results show that the application of N and P in combination with organic manure would be an efficient way for raising crop yields and had little accumulation of NO-3-N in soil profile
