摘要(Abstract):

以发光二极管作为照明光源,利用5种不同光配方的LED灯(7R/1B、5R/1B、4R/1B、3R/1B、2R/1B)在室内对水培番茄进行全人工光照明试验,以探究LED灯不同光质对番茄生长形态特征的影响。结果表明:红蓝配比3R/1B的LED灯照明处理的番茄总体比其它几种光配方的照明处理的更有利于番茄形态生长。株高、节长合理,茎干粗壮,第一穗、第二穗及单株果数多,穗果重、单株总质量更大,单粒果重,第一穗及单株坐果率都比较高,第二穗果糖度最大。2R/1B照明处理的番茄植株矮、节间短、叶片短、穗高矮,生长形态优势一般。5R/1B照明处理各时期叶片基本是各处理中最长的。不过第一穗、第二穗、单株总结果的果数最少,第二穗果重、单株果总重最小,第二、第三穗果单颗果粒较轻,第一穗坐果率和单株总坐果率较低,对提高番茄质量产量效果一般。7R/1B照明处理的后期番茄植株顶端优势明显,茎干纤细,直径基本为处理中最小,第一穗果单颗果粒均值最轻,糖度低,徒长趋势明显,不利于健苗壮苗。这一试验结果对以后番茄种植栽培和LED类研发都有着一定的指导与借鉴意义。
5 LED light of different formulations( 7 R/1 B,5 R/1 B,4 R/1 B,3 R/1 B,2 R/1 B) were used to conduct indoor artificial lighting test on tomato,in order to explore the impact of LED lamp with different light quality on morphological characteristics of tomato growth. The results showed that: the tomato plant processed by the 3 R/1 B LED lighting overall has better impact to the growth of tomato morphology than several other light: Plant height,internode length,stem stout,first ear,second ears and fruit number,fruit weight per panicle,total mass,single fruit weight,spike per plant and fruit rate,all these indicators are higher The tomato plant processed by the 2 R/1 B lighting produces short tomato plant,short internodes,short leaf,ear height,with ordinary growth advantage. 5 R/1 B lighting in each period produces the most leaf length. But the first and second spikes,has least fruit number per plant; spike two fruit weight and fruit weight per plant are the smallest the single fruit is lighter on spike two and three; the first panicle setting rate and total fruit rate is low. Overall its effect to improve the tomato quality and yield is ordinary.7 R/1 B lighting processing has obvious advantages to the latter period of tomato plant height. The stem is slender,with smallest diameter; the first spike has lightest average fruit weight,low sugar rate,whose energy is obviously wasted on plant growth itself. The test results have certain guidance and reference to future tomato cultivation and LED R&D and production.
