| 摘 要： | 目的]为解决内蒙古东部大兴安岭东南地区由于零灌溉所带来的"单产不高,总产不稳"等问题,确定适合于当地的高产高效节水型灌溉制度。方法]以当地主要作物大豆为供试作物,开展了喷灌条件下的作物产量、水分生产率和经济效益等方面的研究。结果]当地原有的零灌溉农业种植模式并不能为大豆的种植提供足够的水分,采用喷灌技术追加2次灌溉,大豆可增产20.0%,但是经济效益并没有提高;追加4水灌溉,虽然总收益最高,但是大豆的作物水分生产率却相比3水灌溉小了很多,造成了不必要的水资源浪费。结论]在开花期、结荚期和鼓粒期分别对大豆增加3次灌水定额为200m3/hm2的灌水,不但可以提高大豆的产量(增产47.8%),而且可以获得最大的经济收益。

| Abstract: | Objective] In order to address the "low yield" issue caused by no irrigation in the east Greater Khingan Range region of Inner Mongolia, high yield and high efficiency irrigation programs are needed in this region.Methods] We took the traditional soybean as the test crop, to investigate the crop yield, water productivity and economic benefits under sprinkler irrigation system.Results] The local agriculture model could not provide enough water for soybean growth without irrigations. The soybean yield increased by 20% when irrigated 2 times by using the sprinkler irrigation technique, but the economic benefits were not improved. The total soybean yield was the highest when irrigated 4 times by using the sprinkler irrigation technique, but the soybean crop water productivity was lower, compared to the crop irrigated by 3 times, and unnecessary waste of water resources occurred.Conclusion] By 3 times irrigation with 200 m3/hm2 quota of water in different growing periods(flowering, fruiting and seed filling periods) of soybean, the soybean production can be increased by 47.8%, and the maximum economic benefits can be obtained. |
