摘    要:采用膜下滴灌种植方式,研究黑龙江大庆地区玉米基于叶龄指数管理的氮肥施肥次数及施氮量对玉米干物质积累、氮素利用率以及产量形成的影响。结果表明,在3次追肥(T3,叶龄指数30%、60%、100%等比例3次追肥)条件下、追氮量为120 kg/hm~2处理时,玉米子粒产量最高,为12 405.29 kg/hm~2,显著高于T3条件下其他追氮量处理,显著高于覆膜传统追肥处理和覆膜不施肥处理。在追氮量为120 kg/hm~2处理下,T3显著高于T2(叶龄指数30%和60%等比例2次追肥)和T5(叶龄指数30%、45%、60%、100%、抽雄吐丝后15 d等比例5次追肥)追肥处理(P0.05)。成熟期氮素吸收量表现为T3处理、追氮量150 kg/hm~2时最大,达241.82 kg/hm~2,比T2和T5追肥处理提高3.8%和1.6%,比T3处理下各追氮量处理提高0.6%~37%。

关 键 词:玉米  膜下滴灌  氮肥利用率  干物质积累

Abstract:The planting mode of drip irrigation under film was used to study maize varieties in Daqing area of Heilongjiang maize based on the effects of leaf age index management of nitrogenous fertilizer application times and application amount of nitrogen on maize dry matter accumulation and nitrogen utilization efficiency and yield formation. The results showed that, in 3 dressing(T3) conditions, nitrogen application of 120 kg/ha treatment, the maize grain yield reached the highest 12 405.29 kg/ha. Significantly higher than the others nitrogen application of T3 conditions processing. Significantly higher than the traditional fertilization, and higher than the film without fertilization treatment. In the treatment of 120 kg/ha, 3 times topdressing was significantly higher than that of 2 times(T2) and 5 times(T5) top dressing. Maturity nitrogen absorption performance that 3 times topdressing(T3) and to recover the amount of nitrogen 150 kg/ha up to the maximum 241.82 kg/ha, more than 2 times (T2) and 5(T5) fertilizer treatment 3.8% and 1.6%, more than 3 times dressing process(T3) others nitrogen application processing 0.6%-37%.
Keywords:Maize  Drip irrigation under mulch  Nitrogen use efficiency  Dry matter accumulation
