中文摘要	探究是否可以将行距比例和种植密度集成于同一作物生产系统中来提高作物产量,增加水分利用效率。以玉米五谷568为研究材料,于2017-2018年进行大田试验,设7∶3(L_1,宽行56cm∶窄行24 cm),6∶4(L_2,宽行48cm∶窄行32cm),5∶5(L_3,等行距40cm)3个行距比例水平,82 500株/hm~2(D_1)、90 000株/hm~2(D_2)、97 500株/hm~2(D_3)、105 000株/hm~2(D_4)、112 500株/hm~2(D5)5个种植密度,探讨不同行距比例及密度处理对玉米的耗水特征、产量及水分利用效率的影响。结果表明,L_1行距比例可有效降低玉米耗水量,但会增加棵间蒸发,对E/ET影响不显著,其中2017年L_1较L_3能有效降低耗水量11.9%,2018年无显著差异;此外与传统行距比例相比,L_1行距比例具有增产优势,玉米增产5.2%~ 10.5%,提高水分利用效率6.5%~8.7%。密度间比较,D_3密度较传统密度D_1能有效降低耗水量、棵间蒸发量以及E/ET,对玉米增产及水分利用效率的提高有促进作用;其中D_3密度较传统密度D_1耗水量降低13.3%,2018年差异不显著;棵间蒸发量减小7.1%~7.2%;E/ET减小6.8%~19.2%;玉米增产7.5%~ 17.1%;水分利用效率提高23.9%~46.2%。2年L_1D_3较传统处理L_3D_1耗水量降低12.8%~30.6%;棵间蒸发量降低8.5%~10.4%;E/ET降低7.3%~7.5%;玉米产量增加7.7%~25.5%;水分利用效率提高36.0%~41.2%。因此,在河西绿洲灌区,7∶3(L_1,宽行56cm∶窄行24cm)行距比例结合97 500株/hm~2(D_3)种植密度可有效增加玉米产量,提高玉米水分利用效率。
英文摘要	The objective of this study was to explore whether the integration of row spacing ratio with planting density in one cropping system will increase water use efficiency ofWugu 568'maize at the Oasis Irrigation District.A field experiment was conducted at the Oasis experimental station from 2017to 2018,to investigate the above objective.Three row spacing levels were used in the ratio;7∶3(L_1,56cm wide∶24 cm narrow),6∶4(L_2,48cm wide∶32cm narrow),and 5∶5(L_3,equal row spacing 40cm);with five plant density levels,thus,82 500plants/hm~2(D_1),90 000plants/hm~2(D_2),97 500plants/hm~2(D_3),105 000plants/hm~2(D_4),112 500plants/hm~2(D5).The primary objective of this research was to investigate the effect of different row spacing ratio and planting densities on water consumption,grain yield and water use efficiency of maize.The results showed that row spacing ratio of L_1can effectively reduce the water consumption and increase the evaporation between rows and has no significant effect on E/ET.Among the treatments,L_1can effectively reduce water consumption by 11.9%compared with L_3in 2017,and there was no significant difference in 2018.Comparing the row spacing ratio,the L_1row spacing ratio has the advantage of increasing grain yield by 5.2%~10.5%,and improving water use efficiency by 6.5%~8.7%.By comparing the density treatments,D_3 density can effectively reduce water consumption and the evaporation between rows,and E/ET as compared to the traditional density D_1.The treatment D_3is 13.3%lower than that of the traditional density D_1and promoted and increased corn yield and water use efficiency.In 2018,the difference was not significant;the evaporation between rows decreased by 7.1%~7.2%;E/ET decreased by 6.8%~19.2%;increased grain yield by 7.5%~17.1%;and also increased water use efficiency by 23.9%~ 46.2%.Comparing the traditional treatment L_3D_1 water consumption to L_1D_3in two years,it reduced by 12.8%~30.6%.The evaporation between rows reduced by 8.5%~10.4%;E/ETreduced by 7.3%~7.5%;water use efficiency improved by 36.0%~41.2%,and increased the grain yield by 7.7%~25.5%.Therefore,7∶3(L_1,56cm wide∶24cm narrow)row spacing ratio combined with 97 500plants/hm~2(D_3)plant density can effectively increase maize yield and improve maize water use efficiency in Hexi oasis irrigation area.
