【目的】研究稻草覆盖或厢边种植大豆等农艺措施对玉米产量、氮磷钾养分利用和径流损失的影响,为探索旱地作物高产高效种植的有效农艺措施提供科学依据。【方法】采用田间小区试验,设不施肥且无农艺措施（CK）、施化肥但无农艺措施（CF）、施化肥+覆盖稻草（CF+R）、施化肥+厢边种植大豆（CF+S）和施化肥+稻草覆盖+厢边种植大豆（CF+R+S）5个处理,探讨稻草覆盖和厢边种植大豆对玉米产量、氮磷钾养分利用及径流损失的影响。【结果】与CF处理相比,CF+R和CF+R+S处理的玉米产量分别显著增加16.0%和23.2%（P0.05,下同）,氮、磷、钾径流损失量显著减少33.6%和40.2%、38.0%和40.0%、38.8%和46.6%。CF+S...

【Objective】In order to explore the effective agronomic measures for high-yield and high-efficiency cultivation in upland,the effects of the agronomic measures of rice-straw mulching and planting soybeans around maize blocks on yields,utilization and runoff losses of nitrogen(N),phosphorus(P)and potassium(K)in crops systemstudied were studied.【Method】Field plot experiments were conducted to investigate the effects of rice-straw mulching and planting soybean around cultivated plots on maize yield,NPK nutrient utilization efficiency and runoff...
