摘要
为突破陇东黄土丘陵区传统种植模式的生产瓶颈,充分发挥区域水热资源优势,提高农田产能,经过连续3 a试验研究和示范验证,早熟马铃薯-粮饲兼用玉米一年两茬生产体系周年产量突破“吨粮”。从整地施肥、起垄覆膜、品种选择、合理密植、田间管理、病虫草害防治和收获等环节总结了早熟马铃薯-粮饲兼用玉米一年两熟种植技术,以期为陇东黄土丘陵区及同类型地区周年高产栽培及资源高效利用提供参考依据。
In order to break through the production bottleneck of the traditional planting mode in the Loess Hilly Region of eastern Gansu,give full play to the advantages of regional water and heat resources,and to improve the productivity of farmland,a continuous 3-year study and demonstration showed that the annual yield of the two-crop-a-year production system of early-maturing potato and grain-forage corn has exceeded'one ton of grain'.Therefore,this paper summarizes the two-crop-a-year planting technology of early-maturing potato and grain-forage corn from the aspects of land preparation and fertilization,ridge formation and film mulching,variety selection,reasonable close planting,field management,prevention and control of diseases,insects,weeds and pests,and harvesting,with the aim of providing a reference for the annual high-yield cultivation and efficient utilization of resources in the region and similar regions.
