蚯蚓粪对西瓜品质和产量的影响

采用露地栽培方式研究了蚯蚓粪不同添加量对土壤肥力以及西瓜产量和品质的影响。结果表明：添加蚯蚓粪明显提高了土壤碱解N、速效P、速效K和有机质含量以及西瓜植株和果实全N、全P、全K含量，有效地提高了西瓜果实中果糖、葡萄糖、蔗糖、VC、番茄红素和可溶性蛋白含量，改善了果实品质，同时还能显著提高产量。施用蚯蚓粪的效果与其施用比例有密切关系，本试验中添加50 %蚯蚓粪的效果最好，全部蚯蚓粪处理比50 %蚯蚓粪处理的效果有所降低，但仍好于其他处理。

Effects of Vermicompost on Quality and Yield of Watermelon

The effects of vermicompost in different volume ratios on watermelon〔Citrullus lanatus（Thunb.）Matsum. et Nakai〕yield and quality were studied. The results showed that the additional vermicompost could significantly increase available N, available P, available K, organic matter contents in soil, and increase the contents of N, P, K in watermelon plants and fruit. The concentrations of fructose, glucose, sucrose, VC, lycopene, and soluble protein were also enhanced. The fruit quality was improved and its yield was remarkably heightened. But the effect of treatment was greatly depended on the applying ratio of vermicompos. In this experiment, treatment with 50 % vermicompost showed the best results, and the full vermicompost treatment had less effect than that of 50 % treatment. But it was still better than other treatments.
