冀中南是我国重要粮食产区,夺取夏玉米高产对实现全年粮食增产,保证粮食安全具有重要战略意义。因此冀中南在夏玉米生产中要紧紧围绕“一增五改”技术(即合理增加种植密度、改种紧凑耐密型高产品种、改套种为直播、改粗放用肥为配方施肥、改人工种植为机械作业、改早收为适时晚收),充分挖掘夏玉米群体增产潜力,实现夏玉米高产、丰收。
Jizhong South is an important grain producing area in China. It is of great strategic significance to seize high yield of summer maize for food production increase throughout the year and ensure food security. Therefore, Jizhongnan should focus on the technology of “one additional and five changes” in summer maize production (ie, rationally increase the planting density, rebuild the compact high-density and high-density varieties, change the intercropping system to live broadcasting, Artificial planting for mechanical operations, the early harvest received timely late closing), fully tap the yield potential of summer maize populations to achieve high summer maize yield and good harvest.
