| 摘 要： | 本试验通过5个密度处理,探讨了大棚番茄春季早熟栽培的适宜密度。结果表明:高密度处理的植株高,茎细,节间长,表现徒长,群体内光照强度随密度增大,下降陡度变大,尤其在冠层以下40cm内更明显;高密度处理座果率下降,果实生长不良,单果重降低,但早期产量较高;总产量以株距30cm为最高,与株距20cm、40cm两处理差异均达显著水平。株距25～35cm是本地区大棚番茄早熟栽培的合理密度。

| Abstract: | The available plant spacing for tomato forwarding culture in plastic greenhouse in spring was studied. The results showed that plant was high, but stem was thin and spindling in the large spacing. The group light intensity decreased significently with the plant spaceing increase, especially for the top 40 cm portion of plant. The fruit setting rate and the weight of fruit were decreased , and the fruit development was not better in the large spacing treament, but the early yield was higher. The total yield was highest in the 30 cm spacing. Compared with the 20 and 40 cm treatments, the difference was statistical significent. It suggested that 25 to 35 cm spacing was available for tomato forwarding culture in plastic greenhouse in this region. |
