摘　　要：以马铃薯冀张薯8号为材料,在现蕾期、开花期、淀粉积累期喷施多效唑和矮壮素,对其叶绿素含量、株高、大小薯数和产量指标进行测定,以期明确马铃薯喷施多效唑和矮壮素的最佳时期。试验结果表明,在现蕾期喷施多效唑和矮壮素,株高最低;开花期喷施多效唑,叶绿素含量、产量最高;淀粉积累期喷施,效果最差。综合试验结果表明,开花期是马铃薯喷施多效唑或矮壮素的最佳生育时期。Under condition of field cultivation,potato JI Zhang No.8 were sprayed with paclobutrazol（PP333） and chlorocholine chloride（CCC） in squaring period,flowering period and starch accumulation period to study their effect on yield constituents.The results suggested that： Spraying PP333 and CCC could increase the yield and chlorophyll content,and decrease the average strain height of potato in all stages.The strain height was lowest in squaring period.The production and chlorophyll content of potato increased most in the flowering period and lest in starch accumulation period.So flowering stage was the best growth period of potato to spray PP333 and CCC.
