在日光温室条件下,以LED 植物生长灯(红蓝光比例7∶2)为补光光源,以不补光为对照,研究不同补光时长(1、
2、3 h)对番茄生长、产量及品质的影响。结果表明:与对照相比,补光2 h 和3 h 均能明显提高番茄的株高、茎粗和叶面
积;补光3 h 能够显著提高番茄的单果质量、单株结果数、产量,以及果实VC、可溶性糖含量及糖酸比,产量增加7.0%,
每667 m2 利润增加528.9 元。综上所述,补光3 h 对促进番茄生长、提高产量及改善果实品质的效果最好。
Under solar greenhouse condition,taking LED plant growth lamp(red and blue 7∶2)as
complementary light source,this paper studied the effects of different filling hours(1,2,3 hours)on tomato
growth,yield and quality. The results showed that compared with the control(without light supplementation),
both 2 and 3 hours could significantly increase the plant height,stem diameter and leaf areas of tomato. Filling 3
hours could significantly improve the single fruit weight,fruit number and yield,contents of fruit VC,soluble
sugar,and sugar-acid ratio. The yield was increased by 7.0%,and profit increased by 7 933.5 yuan·hm-2. In
summary,supplemental light for 3 hours has the best effects on promoting tomato growth,increasing yield and
improving fruit quality.
