摘要
为了研究大葱伴生栽培对日光温室连作番茄植株生长、产量和光合参数的影响,以大葱和番茄为研究对象,测定了番茄植株的株高、茎粗、叶片数、节间长、产量及光合参数。研究结果表明,大葱伴生栽培不改变番茄植株叶片数,但能有效增加番茄株高、茎粗和节间长,且植株长势旺盛;净光合速率、气孔导度和蒸腾速率均明显高于对照处理,且大葱伴生番茄植株的净光合速率与对照处理差异显著。
In order to study effects of accompanied planting welsh onion on greenhouse tomato growth, yield andphotosynthetic characteristics, we took welsh onion and tomato as test materials, investigated plant height, stem diameter,leaf number, internode length, yield and photosynthetic parameters. The results showed that, accompanied planting welshonion didn＇t chang leaf number, but it effectively increased plant height, stem diameter and internode length of tomatowhich grew strongly. Net photosynthetic rate, stomatal conductance and transpiration rate of tomato planted with welshonion were obviously higher than control, and there was a significant difference between it with control in netphotosynthetic rate.
