夏季覆盖对“红地球”葡萄土壤温湿度及果实品质的影响

Effect of Summer Mulching on Soil Temperature and Humidity and Fruit Quality of Vitis viniferacv.'Red Globe'

以3年生日光温室延后栽培"红地球"葡萄为试材,研究了设施葡萄园玉米秸秆覆盖、塑料薄膜覆盖和清耕3种处理对土壤温、湿度及果实品质的影响。结果表明:塑料薄膜覆盖能显著提高土壤浅层温度,而玉米秸秆覆盖保温效果不如清耕。2种覆盖方式均能提高土壤湿度,提高"红地球"葡萄的果实品质;以塑料薄膜覆盖处理效果最好,单果重较CK提高(63.5±0.65)%、果穗重较CK提高(45.0±90.09)%、可溶性固形物含量较CK提高(35.5±1.53)%,维生素C含量较CK提高(124.3±0.15)%,而可滴定酸含量较CK降低(42.2±0.07)%。

Taking a three-year-old prolong cultivated Vitis vinifera cv.‘Red Globe＇in greenhouse as test material,the effect of residue coverage,plastic film mulch,and clean tillage protective measures on soil temperature and humidity and fruit quality were studied.The results showed that plastic film mulch treatment increased soil temperature,while residue coverage kept warm worse than clean tillage conditions.The two covering ways enhanced soil moisture evaporation and fruit quality.Compared with clean tillage conditions,plastic film mulch treatment was the optimal covering way,which could significantly increase single grain weight with（63.5±0.65）%,cluster weight with（45.0±90.09）%,soluble solids content with（35.5±1.53）%,vitamin C content with（124.3±0.15）%,while reduce fruit titratable acidity content with（42.2±0.07）%.
