| 摘 要： | 在宁夏贺兰山东麓葡萄种植基地,以5年生赤霞珠酿酒葡萄为供试材料,布置田间试验,针对葡萄需水需肥规律开展滴灌水肥一体化研究,分析不同灌溉定额及不同施肥量对葡萄产量和品质的影响,确定砾石土壤条件下酿酒葡萄灌溉制度。试验结果表明:随着灌溉定额增加可提高葡萄产量,当灌溉定额为3 825m3/hm2时,产量最大,但超过一定限度后,随灌溉定额增加产量出现下降趋势;增加施肥量在一定程度内可提升葡萄产量。不同施肥量、灌溉定额对单宁影响显著,变异系数分别为25.08及54.03,其他品质指标受其影响不显著,且灌溉定额对品质影响明显大于施肥量影响。减小灌溉定额可在一定范围内提高可溶性固形物含量,减小施肥量能显著降低滴定酸含量,单宁含量增加明显,有利于改善葡萄品质。

Wine Grapes at the Eastern Foot of Helan Mountain of Ningxia Experimental Study on Integration of Water and Fertilizer of Drip Irrigation |

| Abstract: | In eastern Ningxia Helan grape planting base,with 5-year-old Cabernet Sauvignon wine grape for the test material,layout-ed field experiment,then carried out the research on drip and integration of water and fertilizer with irrigation fertilizer requirement regularity of grape water demand,and analysised the different irrigation quota and the effect of different fertilizer on the yield and quality of grape,finally determined the wine grapes of the gravel soil irrigation system.Test results showed that with the increasing irrigation quotas can improve grape yields,when the irrigation quotas was 3 825 m3/hm2 ,the production reached a maximum,but beyond a certain limit,as irrigation increased the yield appeared a downward trend.Increased the amount of fertilizer applied to a certain extent could enhance the grape production.Effect of different fertilizer and irrigation quota on tannin significantly,variation coefficient was 25.08 and 54.03,the other quality indicators did not have a significant effect,qulity effect than fertilization and irriga-tion quota on impat.Reducing irrigation can increase soluble solids content in a certain range,reduce the amount of fertilizer could significantly reduce the acid content,tannin content increases,it can contribute to the improvement of the grape quality. |
