摘要
以"克瑞森"无核葡萄为试材,研究了干旱戈壁地灌水对"克瑞森"无核葡萄根系及果实品质的影响,以提高葡萄产量和土壤水分利用率。结果表明:滴灌条件下葡萄根系在土壤纵向40cm以下的生物量变大,即葡萄果实采摘后的根系相比果实开花前在40～65cm处葡萄根系的分布量增加了26.2%;果实单粒重和果实硬度均随灌溉量的增大呈现出先降低后升高的趋势,而果实横径明显降低;灌溉量为400m3/667m2的处理最佳,产量为730.1kg/667m2,比对照增产62.6%,达到极显著差异水平;葡萄产量与灌溉量的指数模型拟合效果较为理想,相关系数达到了显著性。
Taking ＇Crimson＇ Seedless as test material, the effect of irrigation volume on root system and fruit quality under drip irrigation in arid desert Gobi area were studied. The results showed that under drip irrigation the biomass of root system of grape were enhanced in vertical 40-65 centimeter of soil,namely the amount of root system of grape before bloom increased 26. 2% than after berries pick. Single fruit weight and fruit rigidity firstly decreased with enhance of irrigation volume,then rised slowly,but the diameter transversa was reduced obviously. Especially irrigation volume which was 400 m3/667m2 was best,their yield was 730. 1 kg/667m2 which was 62.6% than the control,the yield of grape and the irrigation volume match index number function a relation,the coefficient was very clearly.
