同步叶片修剪对温室番茄产量与植株发育的影响

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（leaf area index, LAI）从2.9 m2/m2降至2.4 m2/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

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.
