西辽河流域宜机收玉米品种鉴选试验

Identification and Selection of Corn Varieties Suitable for Machine Harvesting in the Xiliao River Basin

为筛选出适宜西辽河流域种植的宜机收玉米品种,根据相关选择标准,对内蒙古自治区内外新审定或引进的品种进行了产量、籽粒含水率、倒伏倒折率、籽粒破碎率等指标的对比试验。结果表明:迪卡159、TK601、LH5013个品种适宜在西辽河流域种植,其中,迪卡159、TK601的适宜种植密度为9.0万株/hm^(2),LH501的适宜种植密度为7.5万株/hm^(2)。该试验结果为西辽河流域玉米籽粒直收规模化、机械化提供了重要的品种支撑。

In order to select corn varieties suitable for machine harvesting and planting in the Xiliao River Basin,this paper conducted a comparative experiment on yield,grain moisture content,lodging and folding rate and grain breakage rate of newly approved or introduced varieties both inside and outside Inner Mongolia Autonomous Region based on relevant selection criteria.The results showed that three varieties(Dika 159,TK601 and LH501)were suitable for planting in the Xiliao River Basin.Among them,the suitable planting density for Dika 159 and TK601 was 90000 plants/hm^(2),and the suitable planting density for LH501 was 75000 plants/hm^(2).The experimental results could provide important variety support for the large-scale and mechanized direct harvesting of corn grains in the Xiliao River Basin.
