摘　　要：以欧美杂交种葡萄‘蜜光’为试材,探究聚乙烯(PE)编织物Coverlys TF150^(®)材质的避雨棚膜对树冠和果实微域环境及果实品质的影响。连续两年的试验结果表明:CoverlysTF150^(®)透光率比聚烯烃(PO)膜低11.91%,降低了果面微域温湿度,缓解了高温和强光胁迫。Coverlys TF150^(®)覆盖提高了成熟期果实大小、可溶性固形物、花色苷、总酚、类黄酮和黄烷醇含量,降低了可滴定酸含量。2020和2021年果实百粒质量分别增加2.15%和2.46%,果实可溶性固形物含量分别提高3.70%和3.04%,果实可滴定酸分别降低17.90%和10.53%,果实花色苷含量分别提高18.33%和11.91%,总酚含量分别提高23.30%和13.07%,类黄酮含量分别提高24.00%和19.43%,黄烷醇含量分别提高18.20%和15.58%。CoverlysTF150^(®)覆盖提高了葡萄果实中萜烯类香气物质含量,尤其是里那醇含量,降低了C6醛类如己醛的含量。The effect of rain-shelter film polyethylene(PE)fabric Coverlys TF150^(®)on canopy,fruit microenvironment and fruit quality were investigated by using grape‘Miguang'(Vitis vinifera×V.labrusca)as test material.The experimental results from two consecutive years showed that the light transmittance under CoverlysTF150^(®)is 11.91%lower than that under polyolefin(PO)film,which reduced the temperature and humidity around the fruit zone and alleviated the stress of high temperature and strong light.CoverlysTF150^(®)increased fruit size and the content of soluble solids,anthocyanins,total phenols,flavonoids and flavanols,while reduced titratable acid content.In 2020 and 2021,fruit hundred-grain weight increased by 2.15%and 2.46%,fruit soluble solids content increased by 3.70%and 3.04%,fruit titratable acid content decreased by 17.90%and 10.53%,fruit anthocyanin content increased by 18.33%and 11.91%,total phenol content increased by 23.30%and 13.07%,flavonoids content increased by 24.00%and 19.43%,flavanol content increased by 18.20%and 15.58%,respectively.Coverlys TF150^(®)increased the content of terpenes aromas,especially linalool,while decreased the content of C6 aldehydes such as hexanal aroma.
