摘要
针对贺兰山东麓酿酒葡萄主栽区存在水分利用率低、土壤持水能力较弱等问题,采用田间小区试验,研究不同灌水定额对4年生酿酒葡萄(蛇龙珠)不同指标的影响。结果表明:灌水定额为290 m^(3)/0.067 hm^(2)时促进新梢生长,降低副梢长度;灌水定额为320 m^(3)/0.067 hm^(2)时增加SPAD值,并且提高水分有效利用率,同时,增产效应明显,提高了可溶性固形物,降低了可滴定酸;灌水定额为350 m^(3)/0.067 hm^(2)时,提高了叶柄全氮含量,增加了干物质积累。
In response to the bottleneck issues of low water use and weak soil water holding capacity in the main planting area of wine grapes at the eastern foot of Helan Mountain,drip irrigation technology was used to manage water and fertilizer integration.Field experiments were conducted to study the impact of irrigation quotas on different indicators of 4 old wine grape"Snake Dragon Ball".The results showed that the irrigation quota was 290 m^(3)/0.067 hm^(2),which promoted the growth of new shoots and reduced the length of secondary shoots.The irrigation quota is 320 m^(3)/0.067 hm^(2),which increases the SPAD value and water effective utilization rate.At the same time,the yield increase effect is obvious,with a large increase.In addition,this treatment increases the soluble sol‐ids and reduces titratable acid.The irrigation quota is 350 m^(3)/0.067 hm^(2)to increase the total nitrogen content of leaf stalks and in‐crease dry matter accumulation.
