摘    要:针对宁夏扬黄灌区沙质土壤肥力贫瘠、养分利用率低以及农田生产力弱等问题。通过两年连续田间定位试验,采用裂区试验设计,主处理为不施有机肥(+M)处理和施有机肥3000kghm^-2(+M)处理,副处理为施纯氮0(N0)、75(N75)、150(N125)、225(N225)和300kghm^-2(N300)5个不同氮肥用量,进行滴灌条件下有机肥与氮肥配合施用对玉米产量及土壤肥力状况的研究,探讨施肥对土壤养分、玉米产量的影响,以选择最佳的肥料配比,从而达到玉米高产、优质和土壤培肥的目的。结果表明,有机肥配施氮肥能有效增加土壤有机质、全氮、全磷、速效钾和速效磷含量,促进春玉米干物质累积并提高产量,以有机肥配施纯氮300kghm^-2和225kghm^-2处理的培肥效果最佳。有机肥配施氮150、225和300kghm^-2处理间的玉米产量无显著差异,但较不施氮肥处理产量分别提高了74.21%、91.33%和81.23%,施有机肥处理较不施有机肥处理平均增产24.28%。在试验区的推荐施肥量为3000kghm^-2有机肥配施225~300kghm^-2氮肥。

Abstract:The study focused on the problems of poor fertility, low nutrient utilization and weak productivity in sandy soil of Ningxia provinces. A two-year of continuous field positioning experiment designed by split block, the main treatment for non-organic fertilizer (-M) and organic fertilizer 3000 kg hm -2(+M) treatment, and the secondary treatment for pure nitrogen of 0 (N0), 75 (N75), 125 (N125), 225 (N225), and 300 (N300) kg hm -2, total 5 different nitrogen fertilizer dosages. The aim for this study was to screen the best fertilizer combination for improving soil fertility and achieving high yield, high quality of corn. The application of organic fertilizer combined with nitrogen fertilizer could effectively increase the contents of soil organic matter, total N, total P, available K, and available P, the dry matter accumulation and grain yield of maize, and two treatments of applying organic fertilizer 3000 kg hm -2combined with pure nitrogen of 300 kg hm -2 and 225 kg hm -2 performed the best. There was no significant difference in yield among the treatments of organic fertilizer combined with pure nitrogen of 150, 225, and 300 kg hm -2, these three treatments increased maize yield by 74.21%, 91.33%, and 81.23% respectively compared with that of the treatment without organic fertilizer, and the average yield of organic fertilizer treatments was 24.28% higher than that of non-organic fertilizer treatments. Organic fertilizer combined with pure nitrogen of 225 kg hm -2 to 300 kg hm -2 is recommended in the test area.
Keywords:drip irrigation  organic fertilizer  nitrogen fertilizer  maize yield  water-fertilizer status
