三熟制早稻前期管理是保苗争多穗,为高产奠定基础。中期主攻方向是控制稳长,巩固有效分蘖,提高成穗率,促进根系旺长深扎,壮秆大穗;后期是抓尾促活熟,保穗数,攻粒饱,争粒重。控中期稳长促根壮秆争大穗 Three-crop early rice management is to fight more seedlings fight spike, laying the foundation for high yield. Mid-term main direction is to stabilize the control, consolidate and effective tillering, increase the rate of spike, and promote the root of the wang deep tie, strong stalk big spike; late is to catch the tail to promote live cooked, spike number, attack grain full, grain weight competition. Control of the long-term stability and promote strong stalks big spike
