定西市农科院两个马铃薯项目通过省级验收

        日前,省农牧厅邀请有关专家组成验收组,对定西市农科院主持完成的《马铃薯窖藏病害生物防治技术研究与应用》和《马铃薯脱毒种薯节本高效扩繁技术研究与应用》进行了验收。
  甘肃省农业生物技术专项《马铃薯窖藏病害生物防治技术研究与应用》项目,经调查确定甘肃中部马铃薯窖藏病害14种;应用田间防病、提前杀秧、块茎入库及库型改进和温湿度控制等技术,使重点示范区烂窖损失由项目实施前的26%降至8.5%;研究提出了甘肃中部马铃薯种薯贮藏技术规程,确定了半地下立柱棋布式马铃薯贮藏库为甘肃中部最佳贮藏库类型;应用新技术、新成果,从2009年以来,挽回马铃薯损失7000万公斤,新增产值11200万元。
  《马铃薯脱毒种薯节本高效扩繁技术研究与应用》项目通过对脱毒苗基质改进、植物延缓剂应用,使脱毒苗生产成本降低了10%;通过对不同苗龄移栽、营养配方创新等研究与应用,提高了单株结薯率,使原原种生产成本降低了15%,创新研制出一套标准化的脱毒苗及原原种节本高效生产技术规程。2009年以来,应用新技术累计生产原原种8650万粒,节约成本324.38万元,并在新疆阿勒泰地区青河县示范生产原原种303.6万粒,新增收益106.26万元,共计新增效益430.64万元。
