化学调控剂对马铃薯生理特性及产量的影响

试验结果表明，３种化学调控剂均能促进马铃薯横向生长，抑制纵向生长，且能提高其光合速率和叶绿素含量，作用效果依次为稀效唑、多效唑、壮丰安。３种调控剂可大幅度提高马铃薯产量，稀效唑提高幅度最大，为３０１２％；多效唑次之，为２４００％；壮丰安为１５４２％。考虑到多效唑的残留问题以及对后茬作物的影响，马铃薯栽培中首选化学调控剂应为稀效唑。

Effect of Chemical Regulators on Physiological Characteristics and Yield of Potato

In this paper, the effect of three kinds of chemical regulators on potato was compared. The results showed that three kinds of chemical regulators promoted crossing growth, restrained vertical growth, improved photosynthetic rate and chlorophyll content of potato; the sequence of evident effect were S3307,PP333 and ZhuangFengAn in turn. The yield of potato could be improvd by them too, the increased range by S3307, PP333 and ZhuangFenAn were separately 30.12%, 24.00%, 15.42%, and because the residue of PP333 affected back stubble crops, so S3307 was the best chemical regulator of potato.
