通过田间小区试验和微区筒15N示踪试验对垄作表层施肥（垄面下l～2cm土层处施肥）、垄作中层施肥（垄面下25cm土层处施肥）、垄作底层施肥（垄面下45cm土层处施肥）和平作表层施肥（常规耕作，1～2cm土层处施肥）的小麦生长发育及氮肥肥效的变化开展了研究。结果表明，在垄作条件下，施肥越深，氮肥利用率越高，即垄作表施（14.52％）＜垄作中施（16.53％）＜垄作底施（20.56％）;与其它处理相比，平作表施（23.78％）的氮肥利用率值最大。地上部生物量及叶面积系数在小麦各生育期通常是平作表施和垄作中施＞垄作表施和垄作底施。
Field experiment and micro-canister 15N tracing experiment were conducted to study the effects of surface fertilization on the top of the ridge (fertilization at the l ~ 2cm soil layer under the ridge), middle fertilization on the ridge (fertilization at 25cm under the ridge) 45cm soil fertilization) to make surface fertilization (conventional tillage, fertilization at 1 ~ 2cm soil layer) wheat growth and development and nitrogen fertilizer changes were studied. The results showed that under the conditions of ridge cultivation, the deeper the fertilization, the higher the utilization rate of nitrogen fertilizer, that is, the rate of nitrogen fertilizer utilization was 14.52% (16.53%) in the ridge and 20.56% in the ridge (20.56%). Compared with other treatments, The nitrogenous fertilizer utilization rate of Shi Shi (23.78%) was the highest. Aboveground biomass and leaf area coefficient are generally flat in the wheat growth stage and the ridge of the implementation of facilities> ridge topography and ridge toping.
