摘要
为了解决‘壶瓶枣’成熟季节遇雨裂果的问题,使其提早成熟,提高经济效益,通过日光温室栽培试验对壶瓶枣物候期、生长量和果型指数进行了研究。结果表明,‘壶瓶枣’的萌芽、初花、盛花、结果和成熟,分别比露地早55、46、53、55、37天。在日光温室内,‘壶瓶枣’根蘖苗、嫁接苗抽枝量比露地分别提高31.7%、30.1%;枣吊数分别增加27.9%、35%;枣吊长度增加14.2%、34.5%;吊果率提高28.8%、23.5%。在0.05的显著性水平下,温室内外‘壶瓶枣’的果形指数存在显著差异。露地栽培的‘壶瓶枣’,果实呈长倒卵形,而温室内枣果近似椭圆。
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.
