[目的]为超级稻中浙优1号蓄留再生稻获得高产提供理论依据。[方法]以品种中浙优1号为研究材料,研究头季稻收割成熟度、收割后留桩时间和定桩高度3个因子对再生稻苗情、有效穗、结实粒数、千粒重和实际产量等的影响。[结果]头季稻在80%、85%成熟度时收割再生稻产量最高;头季稻收割后,留桩时间越短产量越高;定桩高度为10 cm时产量最高,其次是15、20、5 cm。[结论]中浙优1号蓄留再生稻时要掌握好头季稻收割成熟度、留桩时间和定桩高度,才能获得高产。

[Objective]The aim was to provide theoretical basis for high yields on regeneration super rice Zhongzheyou 1. [Method]TakingZhongzheyou 1 as study material,the influences were studied of the maturity on rice first quarter,stubble time and stubble height on the growthof the seedlings,panicles,seed grains,grain weight,real yield and other data. [Result]When the crops first matured at 80% and 85%,theyield was the highest. After harvesting,the shorter the time was,the higher the yield obtained. When the stubble was at a height of 10 cm,the yield was the highest,followed by 15,20 and 5 cm. [Conclusion ]High yield cultivate techniques of regeneration super rice Zhongzheyou1 must master maturity on rice first quarter,stubble time and stubble height.
