Studies On Premature Techniques Of Protected Cultivation For Grape In Turpan City

The Flame Seedless Grape was used for study in this paper as the test materials inTurpan City, combined with conventional facility grape cultivation management measures,using different concentrations of lime nitrogen to break the dormancy of grapes, differentconcentration of gibberellin inflorescence period processing, fruit after repairing spike. Theresults are as follows:(1) Natural condition, the flame seedless grapes to cold quantity for1280h, throughdormant dated January15; Under the condition of constant temperature, cold quantity for1462h, through dormant dated December30.(2) Were the best for20%lime nitrogen to break dormancy and germination period,exhibition leaf stage, early flowering respectively advance the6d,5d,5d.(3) The third phase of the inflorescence spraying ga3concentration of30mg/L, thephysical and chemical indexes reach the optimal value of the plant, the optimization effect isobvious; The fourth phase of the inflorescence spraying ga3concentration of60mg/L, thegrape plants indexes reach the maximum, the inflorescence long, increasing fruit-bearing rate,expands fruit grain of obvious effects.(4) The fourth phase of inflorescence, concentration of gibberellin for60mg/L, evenspraying inflorescence, achieve fruit enlargement, elongated clusters, the purpose ofproduction.(5) Spike grain appearance quality can be improved through (including uniformity,compactness, grain size, etc.), increase the fruit, increase the sugar content, improve the innerquality, significantly improve the flame seedless table grapes product commodity quality, atthe same time, also can early maturity, increase its economic benefits.
