定西市安定区科学规划马铃薯产业布局

      今年,定西市安定区马铃薯种植面积105.41万亩,其中区级标准核心示范基地25万亩,辐射带动全区马铃薯标准化种植75万亩;其中依托旱作农业项目的实施,黑色地膜全膜覆盖马铃薯44.4万亩以上。
      在规模布局上,全区主抓三大生产基地。一是淀粉加工薯生产基地。品种以陇薯3号为主,主要包括东西河流域的凤翔、李家堡、称钩等10个乡镇,总面积40万亩。二是优质鲜销薯生产基地。品种以新大坪为主,主要包括北部巉口、鲁家沟、青岚、西巩等8个乡镇,总面积30万亩。三是脱毒种薯生产基地。以新大坪、陇薯3号为主,由爱兰薯业、旱农中心、凯凯中心、百泉种业4家种薯企业提供原原种4000万粒,以香泉、高峰两乡镇为重点,使全区脱毒种薯面积达到10万亩以上。
      在技术保障上,一是突出以黑色地膜为主的地膜马铃薯种植技术。除在西南部水川区突出推广半膜垄作早上市种植技术外,在其余乡镇推广地膜马铃薯种植面积40万亩。二是突出脱毒种薯应用技术。按照“政府搭台、企业供种、农户种植、订单收购”和“反租倒包土地”的机制扩繁原种6400吨,一级种1325吨。三是突出测土配方施肥技术。坚持重施农家肥,氮、磷、钾配合施用的原则,大力推广配方施肥技术,使全区测土配方施肥应用率达到100%。四是突出病虫害综合防控。在北部和东南部乡镇全面推广稀土旱地宝浸种技术,提高马铃薯抗旱抗病能力。在西南部的内官、高峰、符川等乡镇大力推广宝大森拌种,重点防治马铃薯早、晚疫病。
