烟苗于苗床移栽到露地时,往往由于环境条件骤然变化,不易保全苗,即使成活了,但生长缓慢。为此,我们于1979-1981年在烟苗移栽前进行了囤苗效应的研究。所谓囤苗,即将育成的烟苗,在移栽前六天左右,以烟苗为中心,切成2寸见方的立体土坨,然后按行整齐地排在原畦内,土坨之间弥上细湿土,每天上午喷些清水,以烟苗不严重萎蔫为度。实验结果表明: Tobacco seedlings transplanted to the open bed in the open, often due to sudden changes in environmental conditions, not easy to protect seedlings, even if alive, but slow growth. For this reason, we studied the effect of stocking seedlings before the transplanting of tobacco seedlings in 1979-1981. The so-called store seedlings, about to bred tobacco, about six days before transplanting to tobacco seedlings as the center, cut into 2-inch square three-dimensional soil lump, and then neatly arranged in the original line within the soil, between soil Tuo Mi Fine wet soil, spray some fresh water every morning, with no serious tobacco plant wilting for the degree. Experimental results show:
