鲜食葡萄无核白滴灌水肥一体化试验研究

通过鲜食葡萄无核白水肥一体化试验研究发现，果实膨大期耗水模系数达到50%以上，是鲜食葡萄需水关键期；低氮水平下，鲜食葡萄前期轻度亏水后在后期复水能够刺激新稍分化生长，充分供水条件下较高的施氮水平能够促进葡萄LAI的生长；充分供水条件下高氮有利于葡萄产量的进一步提高，重度亏水下高氮对葡萄产量积累最为不利；轻度亏水能够在保证产量的基础上提高葡萄WUE。

The Integrative Water and Fertilizer Experiment of Table Grape Under Drip Irrigation

The integrative water and fertilizer experiment of table grape under drip irrigation was carried out. The result indicated that the fruit expanding process was the key water requirement and the water consumption coefficient of mould was more than 50%.In low nitrogen level, the water stress in earlier stage and water regain latterly could stimulate the new grape growth.The LAI of table grape was promoted under higher level of nitro-gen in the condition of sufficient water supply ,and the yield could be increased ulteriorly.The higher level of nitrogen was disadvantageous to the yield under severe water deficit ,and the WUE of table grape was in-creased on the basis of ensure production under mild water deficit.
