Abstract: For the purpose of exploring the growth and development of tomatoe during fruit harvest in greenhouse, the experimental data of the greenhouse environmental conditions were collected, and the fruit traits in the harvest period were measured. The test used ‘Provence’ as material and the experimental site was the greenhouse of Xiaotangshan in the Beijing. The results showed that: the daily average greenhouse inside temperature was about 20℃ between March and May, and about 25℃ in June, and the change range of it was smaller than that of outside. The daily average relative humidity of greenhouse was about 70%, while the change of radiation was larger, mostly in the 150-270 μmol/(m²·s). The mean growth of tomatoe plant height per week was decreasing from the mid of harvest to uprooting plants. The mean growth of flower and fruit setting position per week was also decreasing. After fruit setting, it took eight weeks for the fruit to become ripe and to be harvested. The mean growth of fruit transverse and longitudinal diameter per week decreased significantly. The weekly harvest fruit weight decreased first and then increased, and the maximum average weight per fruit was 125.2 g. The weekly production gradually increased to reach a peak of 0.74 kg/(m²·week) and then significantly declined. The mean growth of plant height and flower and fruit setting position per week in the south were slightly larger than that in the north.
