松嫩平原西部地区降水少、蒸发量大、春旱严重,干旱盐碱是限制区域作物产量的主要因素,培育和引种抗干旱耐盐碱作物及其品种,对该地区调整种植业结构、发展粮食生产、提高农民收入意义重大.采用小区试验的方法,对引进的作物新品种"长寿香谷"进行了不同播量试验,并与当地品种进行了对比.结果表明引进作物新品种"长寿香谷",与当地对照品种相比.株高低矮、抗倒伏能力强;分蘖多、产量调节能力大;耐盐碱、抗干旱;穗大、产量高;在特大干旱年份条件下,比对照品种增产11.1%～70.9%.适合在黑龙江省西部干旱轻沙碱地种植.

The western part of Songnen plain is an area with less rainfall,high evaporation and serious drought in spring.The drought and salinization are the main factors to impact crop production there.Therefore, introducing or breeding new crop cultivars with drought and salination-resistance is needed for adjusting cropping system,developing grain production and raising fanners' income.In this study,a filed-plot experiment was conducted.The different densities of a introduced millet cultivar, i.e.longevity fragrant millet, were designed with a local cultivar as control. The results showed that,compared with local cultivars varieties, longevity fragrant millet had lower height,stronger lodging and salination resistance, bigger spike and higher yield. In heavy drought years,the yield is 11.1% - 70.9% higher than control,indicating the new cultivar is suitable for the slight sandy and salinization area in western part of Heilongjiang province.
