[目的]為超級(jí)稻中浙優(yōu)1號(hào)蓄留再生稻獲得高產(chǎn)提供理論依據(jù)。[方法]以品種中浙優(yōu)1號(hào)為研究材料,研究頭季稻收割成熟度、收割后留樁時(shí)間和定樁高度3個(gè)因子對(duì)再生稻苗情、有效穗、結(jié)實(shí)粒數(shù)、千粒重和實(shí)際產(chǎn)量等的影響。[結(jié)果]頭季稻在80%、85%成熟度時(shí)收割再生稻產(chǎn)量最高;頭季稻收割后,留樁時(shí)間越短產(chǎn)量越高;定樁高度為10 cm時(shí)產(chǎn)量最高,其次是15、20、5 cm。[結(jié)論]中浙優(yōu)1號(hào)蓄留再生稻時(shí)要掌握好頭季稻收割成熟度、留樁時(shí)間和定樁高度,才能獲得高產(chǎn)。

Zhongzheyou 1; Regeneration; Stubble time; Stubble height; High yield cultivation techniques

［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．
