烤烟是贵州省的重要经济作物之一。在烤烟育苗阶段,由于贵州气候干旱易造成苗高、苗弱的现象,对后期烟叶的产量和品质造成危害。我所针对这一问题,开展了育苗技术的研究,经过多年的试验研究,研制出了新型烤烟壮苗素。已累计推广400多万亩,并获贵州省科技进 Flue-cured tobacco is one of the important cash crops in Guizhou Province. In the flue-cured tobacco seedling stage, due to the climate aridity in Guizhou, the phenomenon of seedling height and seedling may be caused, which will endanger the yield and quality of the late tobacco leaves. In response to this question, I conducted a research on seedling raising technology. After years of experimental research, I developed a new type of strong seedling of tobacco. Has accumulated more than 400 acres, and access to science and technology in Guizhou Province
