中文摘要	采用二因素二次饱和D-最优设计,于2016-2017年在辽西半干旱区移动遮雨棚内进行了水氮精量控制试验,设灌溉量和施氮量2个因素,灌溉量分别设145.4、271.7、348.2、436.2 mm 4个水平,施氮量分别设0、84.6、 136.1、195.0 kg·hm~(-2) 4个水平,共6个处理。试验分析了水氮交互作用对春玉米产量和水分利用效率的影响,建立了产量回归模型。研究结果表明:浅埋滴灌条件下,灌溉量在145.4~ 350.5 mm时,春玉米产量随灌溉量的增加而增高至11 005.60 kg·hm~(-2) ;灌溉量在350.5~ 436.2 mm时,产量随灌溉量的增加而降低至10 730.09 kg·hm~(-2) ;施氮量在0~ 146.9 kg·hm~(-2)时,产量随施氮量的增加而增高至10 983.19 kg·hm~(-2),施氮量在146.9~ 195.0 kg·hm~(-2)时,产量随施氮量的增加而降低至10 862.39 kg·hm~(-2)。灌溉量因素的影响大于施氮量,水氮之间有明显的正向交互效应,当灌溉量为373.1 mm,施氮量为165.6 kg·hm~(-2)时产量最高。作物耗水量在拔节-抽雄期和灌浆-收获期较大,分别为115.64、127.50 mm;水分利用效率随灌溉量的增加呈逐渐降低趋势,降低幅度达到52.21%,随着施氮量的增加则呈先升高后降低趋势,增幅为14.73%~ 20.08%;其中处理6(灌溉量348.2 mm,施氮量195.0 kg·hm~(-2) )最利于水分利用效率的提高。综合产量和水分利用效率两方面的因素,初步建立了春玉米浅埋滴灌水氮施用优化模式,参数组合为灌溉量348.2 mm、施氮量165.6 kg·hm~(-2)。
英文摘要	A two-factor quadratic saturation D-optimum design was used to carry out water and nitrogen precisely controlled experiment in a mobile shelter in semi-arid area of western Liaoning Province during 2016 to 2017. There were two factors,irrigation and nitrogen ( N) applications. The irrigation rates were 145.4,271.7,348.2 and 436.2 mm,and the nitrogen application rates were 0,84.6,136.1 and 195.0 kg·hm~(-2),respectively,and there were totally 6 treatments. The effects of water and N interaction on yield and water use efficiency were analyzed and a regression model for yield was established. The results showed that the yield of spring maize increased to 11 005.60 kg·hm~(-2) with the increase in water when the irrigation quantity was between 145.4~350.5 mm,and it decreased to 10 730.09 kg·hm~(-2) with the increase of water when the irrigation quantity was 350. 5 ~ 436. 2 mm. When the amount of nitrogen was 0 to 146.9 kg·hm~(-2),the yield increased to 10 983.19 kg·hm~(-2) with the increase in N application. When the amount of N was 146.9 to 195.0 kg·hm~(-2),the yield reduced to 10 862.39 kg·hm~(-2) with the increase in N application. The effect of irrigation was greater than that of N application,there was an obvious positive interaction effect between the two factors,when the irrigation was 373.1 mm and the N application was 165.6 kg·hm~(-2),the yield reached the highest. Crop water consumptions were greater in the jointing-tasseling and the filling-harvesting periods,which were 115.64 mm and 127.50 mm,respectively. Water use efficiency decreased with the increase in irrigation,and decreased up to 52.21%. However,water use efficiency increased first and then decreased with the increase in N application,and it increased in 14.73%~ 20.08%. Treatment 6 ( irrigation volume 348.2 mm,N application 195.0 kg·hm~(-2) ) was most conducive to the improvement of water use efficiency. Based on the results of both yield and water use efficiency,the suitable water-N application pattern for shallow-buried drip irrigation of spring maize was established and the optimum parameters of irrigation amount was 348.2 mm and N application rate was 165.6 kg·hm~(-2) .
