覆膜类型对不同品种玉米资源利用率和经济效益的影响

Effect of Film Types on Resource Utilization and Economic Benefits of Different Varieties of Maize

通过不同颜色地膜对玉米产量和资源利用效率的影响,筛选出优良玉米种植品种,试验表明蓝膜覆盖均较相应白膜覆盖显著提高玉米产量、水分利用效率、光能利用率、经济效益和单方水效益,其中蓝膜先玉335的籽粒产量(15482 kg/hm^2)、水分利用效率(24.99 kg/mm·hm^2)、光能利用率(2.023%)、经济效益(22757元/hm^2)和单方水效益(3.83元/m^3)均最高,说明蓝膜覆盖是区域内节水增产的可行覆盖措施,先玉335是试区适宜栽培推广的玉米品种。

Effects of different color film on maize yield and resource utilization efficiency,excellent maize varieties were screened out.In this investigation showed that blue film significantly improved maize yield,water use efficiency,light energy utilization efficiency,economic benefits and unilateral water benefits compared with corresponding white film,Xianyu No.335 covered with blue film grain yield(15482 kg/hm^2),water use efficiency(24.99 kg/mm·hm^2),light energy utilization rate(2.023%),and economic benefits(22757 yuan/hm^2)And unilateral water efficiency(3.83 yuan/m^3)are the highest,the results showed that blue film is a feasible coverage measure to save water and increase production in the experiment area.Xianyu No.335 is a suitable maize variety for cultivation and popularization in the experimental area.
