不同光质LED灯育苗对设施番茄生长及产量的影响

Effects of Using Different LED Lights to Raise Seedlings on Growth and Yield of Facility Tomato

以益丰4号为试验材料,探讨不同光质(7R3B、8R2B、9R1B)LED灯育苗补光在设施番茄栽培生产中应用的效果。试验结果表明,不同光质LED灯补光育苗时,红蓝光比例为7∶3(7R3B)的LED灯处理下,移栽后番茄的生长、抗逆性、坐果率及产量较好,坐果率90%,增产率18.34%。

Taking Yifeng No.4 as material, we explored the application effects of different supplementing treatments with LED lights （TR3B, 8R2B, 9RI B） on the production of facility tomato cultivation. The results showed tha4 the supplementing treatment （7R3B） with the proportion of red and blue lights of 7：3 could promote the growth, stress resistance, fruit-setting rate and yield of transplanting tomato, with the fruit setting rate and yield-increasing rate of 90% and 18.34% respectively.
