玉米种子催芽包衣处理的芽长及播种时期的研究

Study on Shoot Length and Sowing Period of Corn Seed Lagging Cover Treatment after Germination

以四单１９与北农大生产的种衣剂为材料，研究玉米催芽后不同芽长包衣及包衣后不同播种时期对出苗率及其它幼苗指标生长速度的影响。结果表明，催芽至露白的种子包衣后１２ｈ播种，出苗率优于其它处理，此处理区的幼苗高度、叶数、鲜重以及干重的生长积累速度均好于其它处理。因此，生产上可采用露白的种子进行包衣，包衣后１２ｈ左右再播种，对于干旱、半干旱催芽坐水种植玉米的地区有重要的指导意义。

The resnlt shaved that the germination rate of the treatment that germination was until emergent seed lagging cover after 12 o′clock and sowed was better than other else. The height,leaf number,fresh weight and dry weight of the seeding accnmulation was higher than other So the method may be made use of on production.Corn plantation after germination with as a new technique cand be important direotion in dry and half dry area.
