二作区马铃薯全程机械化绿色高效栽培关键技术

Key Techniques of Mechanized Green and Efficient Cultivation of Potato in the Double Cropping Region

河北省二季作区采用地膜种植马铃薯,2月下旬播种,6月上中旬收获,且不误下茬作物种植,如玉米、大豆、谷子、大葱、秋季蔬菜等,经济效益好,种植面积不断扩大。但目前生产上仍存在机械化应用水平低、施肥利用率低和农药超量使用等问题,限制了当地马铃薯产业发展。因此,为进一步提高二作区马铃薯种植水平,从播前准备、机械播种、田间管理、病虫害防治、机械杀秧与收获6个关键技术环节进行了总结,形成二作区马铃薯全程机械化绿色高效栽培关键技术,指导生产,促进河北省二季作区马铃薯产业健康发展。

In the double cropping region of Hebei Province,potatoes are mainly planted with plastic film mulching,sown in late February and harvested in early to middle June.This planting method does not delay the subsequent planting of maize,soybean,millet,green Chinese onion and other autumn vegetables,which leads to good economic results and growing acreage.However,there are still problems like low level of mechanization,low fertilizer utilization rate and excessive use of pesticides,which restrict the development of local potato industry.For further improvement of the potato cultivation level in the double cropping region,the six key technical links of pre-sowing preparation,mechanical sowing,field management,disease and pest control,mechanical haulm killing and harvesting were summarized to form the key technology of full mechanized green and efficient potato cultivation,which would guide production,and promote the healthy development of the potato industry in the double cropping region of Hebei Province.
