Abstract: Effects of ABT powder for rooting(No.3)and times of seed soaked，sowing period and field-membrane cover on the germination percentage(GP)，formation percentage of seedling(FPS)and growth of seedling are studied in order to increase the efficiency of sowing and cultivating seedling of cycad Effects of photic percentage and leaf-fertilizer on sprouting velocity，GP and chlorophyll contents are also included in this paper． Results showed that concentration of 0．02ug／kg for rooting powder was most useful，making GP and FPS amount to above 60 percentage and being significantly different from the other concentration．Effect of soaking seed time on tested indicators was not obvious．Effect of sowing period on them was distinct and best result was got by means of so wing in April 13．The time needed for sprouting was shorter than that by any other treatment GP and FPS was increased significantly and sprouting time was shortened by means of field-membrane cover．Effects of photic percentage on leaf growth and chlorophyll content were obvious．Sixty photic percentage was most profitable．Leaf growth and chlorophyll content of cycad were enhanced distinctly by use of leaf-fertilizer．
