Abstract: This research was conducted on the aspects of phonological phase, growth rate and shape index of ‘Hupingzao’ date by the application of greenhouse technology. The purpose of it was to solve the problem of the date crack in the rain, and the ultimate purpose was to indicate that more economic profits will be improved by ripping the date ahead of time. From the comparison of the results of the experiment and the traditional method named the open field cultivation, we found that the days of growing roots, flowering for the first time, blossoming and riping completely were earlier than the days of the work be done based on the open field cultivation, which will be 55, 46, 53, 55, 37 d respectively. By the contrast of the conditions we can seen that there was higher sprouting rate of root turion and grafted seeding by the implication the experiment (the rate risen by 31.7% and 30.1%). The number of shedding shoot of ‘Hupingzao’ were increased by 27.9% and 35%, the length of shedding shoot of ‘Hupingzao’ also increased by 14.2% and 34.5%; in addition to the ratio of them enhanced by 28.8% and 23.5% respectively. Therefore, according to the discussion above we can made a conclusion that there was a significant difference in the experiment (P<0.05). And we also learned that on the introduction of the greenhouse technology the ‘Hupingzao’ date shaped approximately oval by the comparison the reverse egg-shaped by the open field cultivation.
