摘要
研究了同步叶片修剪对温室番茄品种“Capita”产量与植株发育的影响。结果表明,在修剪每穗果实为6时,同步叶片修剪显著地将叶面积指数(leafareaindex,LAI)从2.9m2/m2降至2.4m2/m2,从而导致番茄植株总产量显著降低5.2%,但果实产量并未降低。当植株密度从2.5株/m2增加到3.8株/m2时,LAI显著地从2.4m2/m2增加到3.6m2/m2,虽然单位植株的总产量与果实产量分别降低了13.0%与9.0%,但是单位面积植株的总产量与果实产量反而分别增加了32.3%与38.4%。同步叶片修剪与植株密度并不影响植株的发育,对植株高度也没有显著影响。
Effect of synchronous leaf pruning on yield and plant development in greenhouse tomato cultivar 'Capita' was investigated. The results indicated that with 6 fruits per truss leaf area index (LAI) was significantly decreased from 2.9 m2/m2to 2.4 m2/m2 by synchronous leaf pruning, therefore total plant yield was significantly decreased by 5.2%, while no significant reduction was observed in fruit yield. With the increment of plant density from 2.5 to 3.8 plant/m2, LAI was increased significantly from 2.4 to 3.6 m2/m2,which resulted in a increment by 32.3% and 38.4% in total plant yield and fruit yield per square meter, respectively, while a reduction by 13.0% and 9.0% in total plant yield and fruit yield per plant, respectively. Both plant development and height were influenced neither by synchronous leaf pruning nor by plant density.
