补光对日光温室越冬番茄生长及产量品质的影响

Effect of Supplementary Lighting on Growth, Quality and Yield of Tomato Overwintering Stand in Greenhouse

以普通荧光灯为对照,采用不同光质荧光灯(红,蓝,红蓝1∶1)对日光温室内番茄进行定时补光(6:30—8:30,16:00—18:00;光照强度2 000 lx),研究不同光质补光对番茄生长、产量及品质的影响。结果表明,与对照相比,补照红光能够促进番茄植株生长;补照红光和红蓝混合光能提高番茄产量,且补照红光的增产效果最好,产量增加22.4%;可溶性糖含量以红光处理最高,可溶性蛋白、Vc和可滴定酸含量以蓝光处理最高,果实番茄红素含量在红光与红蓝混合光照射下均明显增加。综合评价,补照红光有利于促进番茄生长,提高产量和品质。

In order to study the effected of supplementary lighting on the growth, yield and quality of tomato in greenhouse, different light qualities （red, blue, red ＋ blue 1：1） were used to provide light regularly （6：30--8：30 am; 16：00--18：00, light intensity were 2 000 Ix）, compared with common fluorescent lamp. The results showed that compared with the control, the red light could significantly promote plant growth. Red, red ＋ blue light can both increase the yield, and for red of supplementary lighting the increase of yield weight was 22.4%. Soluble sugar content was the highest under red light, while soluble protein, vitamin and titratable acid content attach the best under blue light. Red, red ＋ blue light treatment can significantly increase the lycopene content in fruit. It is concluded that red light is suitable for the growth and can improve fruit yield and quality of tomato.
