The Influence Of Plant Growth Regulatiors To Potato Yield And Quality

Through Single factor randomized block design in this experiment, four influence for experimenting project were designed, and five groups of plants growth regulating were chosed which were used to go together or signally , the influence of plant growth regulating to potato yield and quality were studied. Through measures appearance index ,physiology index, yield and the quality index of the potato, the growth regulating and its applied techniques which suit potato's production were preliminary blotted.As a result, in baofengsu dosage experiment, the low dosage baofengsu(12 g/30kg water/667 m~2) are the best,. In baofengsu+PP333 dosage expermint, baofengsu dosage(12 g/ 30kg water/667 m~2)+ ppp333 dosage (40 g/30 kgwater/667 m~2) is the most suitable concentration. In PP333 dosage experiment, the concentration NO.3(75 g/30 kgwater/667 m~2) is the best dosage; In PIX dosage experiment, the concentration (15 g/30 kgwater/667 m~2) is the most suitable dosage. Contrasting the four experiments, the low dosage baofengsu(12 g/30kg water/667 m~2) is extremely obvious to potato's production, but PIX dosage (15 g/30kg water/667 m~2) is the most obvious to potato's quality index .
