冬季马铃薯免耕栽培技术

      1.选择良种。根据市场需要和气候特点,建议选用荷兰15号、东农303、克新4号、中薯2号等良种,这些品种早熟、高产、商品率高,芽眼浅,表皮光滑,块茎呈椭圆型,市场畅销。特别注意的是要应用脱毒种薯,不要用市场上的商品薯做种薯。
  2.选择适宜田块。要选择土壤疏松、排灌方便、不渍水的田块种植。特别注意不要选择在地势低洼的田块种植马铃薯,以防止3-4月雨水多时渍水,同时,要避免选择在上造种植过番茄、辣椒、茄子等茄科作物的田块上种植马铃薯,以免易感病害。
  3.选择适宜的季节播种。贺州市地处桂东北,历年在12月下旬至次年1月中下旬霜冻较重,冬种马铃薯易受霜冻危害。因此,在生产上要采取适时播种、避霜栽培的技术措施。根据多年的生产实践和经验总结,我市冬种马铃薯应在12月下旬(即冬至前后)播种为宜,元月下旬出苗,4月中下旬就能够正常成熟收获。
  4.应用配套栽培技术。主要是做好种薯处理、合理密植、科学施肥、免耕栽培、综合防治病虫害等配套技术。建议应用免耕稻草种植马铃薯,免耕马铃薯具有稳产高产、省工节本、优质高效、生态环保等独特优势,其种植技术也非常简单,只要“摆一摆、盖一盖、拣一拣”,就可大功告成。但要取得好的效果,特别要注意三点:第一,要在施足基肥的基础上(每亩沟施腐熟有机肥1000千克和复合肥100千元作基肥,有机肥不足时,亩施复合肥150kg作基肥);先盖好泥,再盖稻草,以提高出苗率、减少禾草用量。第二,盖草的厚度要达5-6厘米,否则马铃薯露光后,青薯多,商品价值下降。第三,生长后期要注意清沟排水,以免渍水导致烂薯。
