不同种植模式对红枣产量和品质的影响

Effect of Different Planting Patterns on Yield and Quality of Jujube

以红枣为研究对象,采用单作(红枣纯林)与混作(红枣×核桃、红枣×扁桃)等3种不同种植模式,对红枣产量和品质进行比较分析。结果表明:不同种植模式的红枣单果质量、产量均差异较大,上坡纯林模式红枣产量最高,红枣×扁桃、红枣×核桃混作模式的红枣产量较低;不同种植模式的红枣总糖含量、总酸含量、维生素C含量均存在差异,下坡红枣纯林、上坡红枣纯林和下坡红枣×核桃3种模式的红枣品质较好;上坡红枣纯林的种植方式既有利于提高红枣产量,又有利于改善其品质。

Jujube was used as research object under three different planting patterns，jujube monoculture，jujube × walnut，and jujube × almond yield and quality of jujube were investigated.The results showed that the difference of single fruit weights and yields under different planting patterns were significantly different.Jujube yield under monoculture uphill was the highest while those under jujube × walnut and jujube × almond were lower.The difference of total sugar content，total acid content，and vitamin C content under different planting patterns were significant.Jujube quality under monoculture uphill，monoculture downhill，and jujube × walnut downhill were all better.Jujube monoculture was not only beneficial for improving the yield，but also improving its quality.
