龙眼园环沟高树盘养蚯蚓综合效应研究

Comprehensive Effects of Raising Earthworms in Circular Ditch on Longan Orchard

对龙眼树盘进行环沟高树盘养蚯蚓、环沟高树盘盖白膜、环沟高树盘盖黑膜和环沟高树盘无膜处理,以无沟无膜处理为对照,测定土壤含水量、有机质、p H,植株根系,果实产量、品质,叶片相对含水量,枝条水势等指标。结果表明:环沟蚯蚓能显著提高树盘及环沟土壤含水量、有机质、p H,增加龙眼根系数目和重量;环沟白膜、黑膜能增加龙眼根系重量与数目,但效果不如环沟蚯蚓,环沟对龙眼根系无显著效果;环沟蚯蚓、环沟白膜、环沟黑膜的叶片相对含水量和枝条水势显著高于对照;环沟蚯蚓在果实产量、TSS、总糖、可滴定酸、Vc均显著优于对照。

In mature longan orchards, four treatments viz. circular ditch and earthworm, circular ditch and black film, circular ditch and white film, circular ditch without film were carried out, and no circular ditch no film as blank. The soil water content, soil organic matter, soil pH, plant root, fruit yield and quality,leaf relative water content and water potential of twigs were determined under the treatments. The results showed that circular ditch and earthworm can improve the soil water content, soil organic matter, soil pH, plant root,leaf relative water content and water potential of twigs; circular ditch and black film, circular ditch and white film can improve the the plant root, leaf relative water content and water potential of twigs;compared with blank, circular ditch and earthworm was better in fruit yield and quality.
