近年来,随着农民机械化种植面积的扩大,市场要求越来越多的高质量玉米杂交种,以适应单位用种量降低所带来的风险。单粒播种已加速普及,根据我国目前的种植要求,相信在不久的将来,玉米杂交种机械化单粒播种必将成为主流,尤其在黄淮海区更是发展的必然。 In recent years, with the expansion of mechanized planting area of ​​peasants, more and more high-quality maize hybrids are demanded in the market to adapt to the risks brought by the reduction of the unit-use quantity. Single grain sowing has accelerated the popularization, according to the current planting requirements of our country, I believe in the near future, mechanized single sowing of maize hybrids is bound to become the mainstream, especially in Huang-Huai-Hai region is the inevitable development.
