葡萄园不同覆盖对红地球果实品质的影响

Effects of different vineyard mulching on fruit quality of Red Globe

以红地球葡萄为试材,通过葡萄园秸秆覆盖、地膜覆盖、生草覆盖和清耕4种处理,研究土壤不同保护性措施对红地球葡萄品质的影响。结果表明:秸秆、地膜和生草覆盖均能显著提高红地球葡萄的果实品质,其中以地膜覆盖处理效果最好,果粒重达到12.24g,较清耕提高22.40%;穗重998.23g,较清耕提高20.79%;可溶性固形物含量较清耕提高12.30%,达到13.88%;有机酸含量为0.36%,较清耕降低50.68%。秸秆覆盖和生草覆盖也能显著改进葡萄品质,秸秆覆盖效果较好。

Effects of residue coverage, plastic mulching, green cover and clean tillage of soil conservation treatments on Red Globe berry quality were studied. The results showed that residue coverage, plastic mulching and green cover could improve the berry quality obviously. Of the treatments, plastic mulching did the best. The average berry weight, cluster weight, soluble solids, were 12.24g, 998.23g, and 13.88%, respectively, which were 22.40%, 20.79%, and 12.30% higher than that from under clean tillage. The organic acid content was 0.36% with a 50.68% decrease of that under clean tillage. Residue coverage and green cover could also improve berry quality, and residue coverage could do better.
