    Abstract:

    [Objective] The effects of moisture in Hexi desert oasis area(taking Zhangye City in Gansu Province as the representative) on soil temperature was demonstrated and the association between soil temperature and fruit quality was explored to provide theoretical basis for facility delayed cultivation technology research.[Methods] Five growth stages(GS, PS, FS, ES, CS) were recognized for the cultivation of faculty-delayed grapes. In each growth period, a moderate moisture treatment(the lowest of soil moisture was about 55% of the soil field capacity).[Results] (1) Soil temperatures of different layers ranked as 5 cm > 10 cm > 15 cm > 20 cm > 25 cm. During the whole growth period of grape, the soil temperature in each soil layer increased first and then decreased. Water stress at certain growth stage not only improved soil temperature, but also played an important postponed role in soil temperature to the next growth stage. (2) GS treatment had the highest ear quality and greatest single grain weight; FS treatment had the highest soluble solids content; the total sugar content of CS treatment was the most; titratable acid content was lowest in CS.[Conclusion] Soil temperature of the grape was significantly affected by environment during the delayed cultivation. Soil heat was transferred from the surface layer to the deep layer during the daytime, and hence water stress can increase soil temperature. In order to increase the sweetness of the grapes, to reduce the acidity and to increase the maturity, soil temperature should be increased in the late growth stages. They are the fruit swelling stage and the coloring mature stage.
