根据９年的田间定位试验资料，我们分析了９种不同施肥处理黑垆土耕层（０～２０ｃｍ）、古耕层（２０～５０ｃｍ）和垆土层（５０～８０ｃｍ）三层土壤养分的变化。结果表明：施肥对黑垆土剖面养分的影响随深度的增加而减弱，一般为，耕层＞古耕层＞垆土层。不同处理耕层土壤养分差异比较明显，耕层以下土层尽管差异减小，但其养分变化与耕层趋势一致。各层土壤速效养分对照比裸地均有下降。综合评价施肥对黑垆土剖面的培肥效果，ＮＰＭ＞Ｍ＞ＰＭ。
According to the data of 9 years of field experiment, we analyzed the nutrient contents of three layers of black soil layer (0 ~ 20cm), old layer (20 ~ 50cm) and soil layer (50 ~ 80cm) Variety. The results showed that the effect of fertilization on the nutrients in black loess soil decreased with the increase of depth. Generally, the effect of fertilization on topsoil was> topsoil> loess soil. The differences of soil nutrients in different treatments were obvious. Although the differences of soil layers below the top layer decreased, the changes of nutrients in soil layer were the same with those of top layer. The soil available nutrients in all layers were lower than bare land. Comprehensive evaluation of fertilization on the black soil profile of the effect of fertilization, NPM> M> PM.
