Abstract:
‘Dongnong722’ tomato was used as material,eight kinds of plant growth regulators which were PCPA,Fruit capsule,2，4-D,Fengchanji No.2,Swell king,Boron fertilizer,Plant essence and Fruit swell agent were selected to study what influences of different plant growth regulators on growth period of tomato,fruit setting rate,deformity fruit rates,appearance quality and yield.The results showed that the treatments of different plant growth regulators could make harvest time in advance,improve the tomato fruit setting rates and increase the pre-yield and total yield to a certian extent compared with the control.For Fengchanji No.2,the stage of fruit setting,color change and harvest were earlier than other treatments and the harvest data was six days in advance than control.For the first fruit of PCPA,Fruit capsule,2,4-D and Fengchanji No.2,the fruit setting rate were all 100.00%,which were significantly higher than the control.The fruit setting rates of Fruit capsule and Fengchanji No.2 were relatively higher for the second fruit and were 100.00%,97.22% respectively.For the third and forth fruit,the fruit setting rates of Fengchanji No.2 was higher than other treatments.The deformity fruit rates of the first,second and forth fruit were no significant differences among treatments.The fruit shape indexes of Swell King and Boron fertilizer were 0.85,which were higher than other treatments and there were no significant differences among treatments.,their shape were all close to circular.The 667 m2 pre-yield and 667 m2 total yield of Fengchanji No.2 were higher than other treatments and were 2 934.12 kg，5 987.99 kg respectively,which were significantly higher than control.PCPA was slightly lower than Fengchanji No.2.The results showed that Fengchanji No.2 stage of fruit setting, color change and harvest were earlier than other treatments, and it was higher fruit setting rates,lower deformity fruit rates, but could effectively improve 667 m2 the pre-yield and total yield effectively.
