	<span style=\"font-size:14px;\">推广和利用耐旱作物和耐旱品种，是提高干旱地区农作物单位面积产量的一项有效措施。为了验证以GPIT生物技术育种手段育成的大穗玉米的耐旱性和丰产性，2017年通过在山西省永和县雨养旱地进行比较试验。结果表明：大穗玉米在3个试点的耐旱丰产性均比不同对照(CK)品种好，3个试点平均比对照(CK)每公顷增产3850 kg，平均增幅30.16个百分点。说明GPIT生物技术的高光效作用在大穗玉米的耐旱性和丰产性上得到具体体现。大穗玉米不仅适应高水肥地种植，在山区、丘陵雨养干旱地区同样具有广阔的应用前景。<br />
Popularizing and using drought-tolerant crops and varieties are an effective measure to improve the yield per unit area of crops in arid areas. In order to verify the drought tolerance and fertility of large-spike corn bred by GPIT biotechnology breeding method, a comparative test was conducted in rainfed dry land of Yonghe County, Shanxi Province in 2017. The results show that: the drought-resistant and high-yield properties of large-ear maize in the three pilot projects are all better than those of different CK (three pilot projects), and the average yield increase per hectare is 3850 kg, and the average increase rate is 30.16 percentage points. It indicates that the high light efficiency of GPIT biotechnology is embodied in drought tolerance and fertility of large-ear corn. Large ear corn is not only suitable for planting in high water and fertilizer fields, but also has broad application prospects in rain-fed arid areas in mountainous and hilly areas.</span>
