摘要
通过5个密度对大棚番茄越夏连秋栽培进行了研究,其结果:1.随着密度的增加,株高、节间增长,茎粗减小,植株趋向于徒长;2.叶片数以密度为120×30cm者为最多,群体内光强随密度的增加而减弱;3.单果数随密度的增加而减少;单果重以行株距为120×30cm的处理为最重。产量随密度而变化,其总产量有显著差异,以120×30cm的产量最高;120×20cm的产量较高。
5 planting densities of tomato cultured from spring to autumn in plastic house were studied. The results showed that (1) with the increase of planting density the height of plant and length of internode increased and the girth of stem decreased and the plants tended to spindle; (2) the leaf quantity of each plant was the largest in the density of 120×30cm, and light intensity decreased with the increase of planting density; (3) the fruit quantity of each plant decreased with the increase of planting density;the average weight per fruit was the biggest from the density of 120×30cm.The yield varied with the change of planting density and total yield differred significantly from one another. The best yield was obtained from the density of 120×30cm followed by 120×20cm.
