| 摘 要： | 为确定山西省北部地区膜下滴灌玉米适宜的种植密度和灌溉制度,于2015年在山西省阳高县进行了大田玉米膜下滴灌试验。研究分析了不同种植密度和灌水次数组合对玉米田水分含量、水分消耗量、植株生长发育状况、水分利用效率的影响。结果表明,种植密度、灌水次数均对玉米生长具有明显影响,进而影响到玉米产量。在种植密度8.25万株/hm^2、生育期内灌水3次的组合下,玉米的长势、水分利用效率、产量均最高,产量达到8418 kg/hm^2,耗水量为4057.03 m^3/hm^2,水分利用效率达到2.08 kg/m^3,是最佳的种植密度和灌溉次数组合模式。

| Abstract: | In order to determine the suitable maize planting density and irrigation mode in the north region of Shanxi Province,the experiment of mulched drip irrigation is carried out in the maize field in Yanggao County,Shanxi Province in 2015.The effects of various combinations of planting density and irrigation times on water content,water consumption,the growth and development of plant,and water use efficiency in maize fields are studied.The results show that the planting density and irrigation times have a significant effect on maize growth,which affects maize yield.Under the combination of the planting density of 82500 plants/hm^2 and the irrigation times of 3 during the growing period,the growth,water use efficiency and yield of maize are the best.It is the optimum combination with a yield of 8418 kg/hm^2,a water consumption of 4057.03 m^3/hm^2,and a water use efficiency of 2.08 kg/m^3. |
