| 摘 要： | 针对黑龙港流域干旱少雨、地下水资源由于超量开采而严重匮乏的局面，河北省农林科学院旱作农业研究所立足于黑龙港流域的生产和气候特点，以区域内两大主要节水作物——油葵和夏玉米为试验材料，以7月5日轮作直播玉米为对照，在套播条件下研究了不同种植模式（60cm等行距，40cm＋80cm宽窄行）和玉米不同播期（6月20日、25日和30日）对单位面积经济效益的影响。结果表明：油葵．夏玉米套播时，采用宽窄行种植、6月25日播种玉米，单位面积经济效益最高，达到了40080元／hm2。在黑龙港流域可以采用油葵一夏玉米套播种植模式，部分替代目前耗水量巨大的小麦一夏玉米轮作模式。

| Abstract: | For against the serious shortage of groundwater due to drought and over-exploitation in Heilonggang river valley. According to the production and climatic characteristics of the area, within the region two major watersaving crops oil sunflower and summer maize were taking as the materials, the maize sowed on July 5 with rotation was using as control, in the interplanted conditions, the effects of different cultivation mode （60 cm of row spacing, 40 cm ＋ 80 cm of narrow and wide row spacing） and different sowing date （June 20, 25 and 30 of maize on economic benefit of unit area were studied. The results showed that in the condition of oil sunflower and summer maize interplanted, using the narrow and wide row spacing and sowed maize on June 25, in which the economic benefit of unit area was highest （40 080 yuan/hm2）, in Heilonggang river valley, the cultivation mode of oil sunflower and summer maize interplanted could be used to partially replace the wheat and summer maize rotation mode with huge water consumption at present. |
