摘　　要：木薯采用促根剂浸种,可有效提高出苗率,促出壮苗。于幼苗期叶面喷施宇花灵1号,可促进幼苗快速生长,于块根膨大初期叶面喷施宇花灵5号,可有效调节植株营养生长与生殖生长关系,促进块根生长。试验结果表明,采用促根剂浸种与叶面喷施宇花灵相结合,可有效提高木薯的产量和淀粉含量,可使木薯产量提高29.5%,鲜、干淀粉含量分别提高9.23%和9.22%,增产增效明显。Using＂promote root agent＂ soaking cassava＇s stem, could effectively improve germination rate, promoting a strong sprout. Spray on the leaf blade with ＂Yu Hua Ling＂No.1 in seeling time, could promote the seedling fast growth, spray on the leaf blade with ＂Yu Hua Ling＂No.5 in the bloCK root expands the initial period, could effective adjustment relations of adult plant vegetative and reproduction growth, promotion the bloCK root to grow up. The result show that, Using ＂promote root agent＂ soaking and spray on the leaf blade with ＂Yu Hua Ling＂ of the cooperative application , Coule increase the yiele of root tuber and the starch content, Could increase the yiele of root tuber by 29.5%,and it＇s starch content by 9.23% and 9.22% of it＇s Fresh and dry, The production increase efficiency is obvious.
