摘要：

【目的】黄土旱塬半湿润易旱区属于雨养农业区,水分亏缺为主要限制因素,因此,有必要筛选适于黄土旱塬半湿润易旱区春玉米综合栽培模式,从而提高旱地春玉米水分利用效率和产量。【方法】 2017—2018年玉米生长季,探讨不同耕作方式（翻耕、免耕、深松）、施氮（0、150、225 kg·hm^-2）和种植密度（52 500、67 500 株/hm²）对春玉米田土壤水分动态、水分利用效率、春玉米生长、产量及其构成因素的互作效应,提高玉米综合生产力。【结果】（1）2017—2018年春玉米播种期0—200 cm土层土壤蓄水量均表现为免耕>深松>翻耕,2年平均免耕与深松播种期0—200 cm土层土壤蓄水量较翻耕分别提高6.1%和4.1%。2年春玉米水分利用效率均在深松高密高氮（STH2）处理最高。（2）深松与免耕处理较翻耕处理显著提高叶面积指数与干物质积累量,随密度与施氮量的增加,春玉米叶面积指数与干物质积累随之增加,耕作×密度对拔节、抽雄期叶面积指数有显著影响,密度×施氮对灌浆中期叶面积指数有显著影响。STH2处理下,玉米成熟期干物质积累量较其他处理提高3.3%—32.9%。（3）穗粒数和百粒重与施氮呈显著正相关关系（P<0.05）,深松与免耕处理玉米产量显著高于翻耕。STH2处理产量最高,2017年STH2产量较其他处理增幅为1.4%—63.3%;2018年增幅为2.9%—39.6%。【结论】在黄土旱塬半湿润易旱区,深松耕配施150—225 kg·hm^-2施氮量与67 500株/hm²种植密度,不仅可以提高春玉米水分利用效率,还可获得较高的玉米产量效益;免耕配施225 kg·hm^-2施氮量与67 500株/hm²种植密度,可获得较高的经济效益。

Abstract:

【Objective】The semi-humid and arid areas on the Loess Plateau belong to rain-fed agricultural areas, in which water deficit is the main limiting factor for agricultural production. Therefore, a comprehensive cultivation mode of spring maize suitable for semi-humid and drought-prone areas on the Loess Plateau was screened to improve maize water use efficiency and yield. 【Method】During the 2017 and 2018 maize growing season, the effects of different tillage methods (conventional tillage, no-tillage, and subsoil tillage), nitrogen application (0, 150, and 225 kg·hm^-2) and planting density (52 500 and 67 500 plants/hm²) on soil water dynamics, water use efficiency, crop growth, yield and its components in spring maize field were analyzed to improve the comprehensive utilization of maize. 【Result】 (1)The soil water storage (0-200 cm) of spring maize before sowing in 2017and 2018 showed the trend of NT>ST>CT, which under NT and ST increased by 6.1% and 4.1% than that under CT, respectively. In addition, water use efficiency was the highest under STH2 treatment during two consecutive years. (2) Compared with conventional tillage treatment, subsoiling and no-tillage treatment significantly increased leaf area index (LAI) and dry matter accumulation. LAI and dry matter accumulation of spring maize increased with the increase of density and nitrogen rates. The tillage×density interaction had significant effect on LAI at jointing and tasseling stages, and the effect of density×fertilization interaction had significant effect on LAI at filling stage. Compared with other treatments, the dry matter accumulation of STH2 treatment in maturity stage increased significantly by 3.3% -32.9%. (3)There was a significant positive correlation between nitrogen application and the number of grains per ear and 100-grain weight; the maize yield under subsoiling and no-tillage treatment was significantly higher than that under conventional tillage, among which the yield under STH2 treatment was the highest, and compared with other treatments, the maize yield under STH2 treatment increased by 1.4%-63.3% in 2017 and 2.9%-39.6% in 2018. 【Conclusion】Under the condition of subsoiling tillage, applying 150-225 kg·hm^-2 nitrogen and 67 500 plants/hm² planting density could not only improve water use efficiency of spring maize, but also obtain higher yield benefit, no-tillage, applying 225 kg·hm^-2nitrogen and 67 500 plants/hm² planting density could get the high economic benefit.
