不同宽度地膜覆盖对西瓜栽培效果影响对比试验

Effects of Mulching Polythene Film with Different Widths on Watermelon Cultivation

采用田间栽培对比试验,研究分析了不同宽度地膜覆盖西瓜种植畦对西瓜植株生长状况、产量和品质形成的影响,寻找适合华南地区冬、春、秋干旱,夏季多雨气候环境下,能很好调节土壤水分和肥料,满足西瓜植株正常健康生长所需的栽培技术方法。试验结果表明,在同等的栽培管理条件下,覆盖100 cm宽黑色地膜效果最好,在种植后遇到干旱或下雨季节,其对土壤的保水及防水能力,提高肥料的利用率,提高西瓜产量及品质等方面都有明显效果,可作为我国华南地区冬、春、秋干旱,夏季雨水偏多气候环境露地西瓜生产栽培模式技术。

In this paper, we studied the effects of covering polythene film with different widths on the furrow on the growth, yield and quality of watermelon, to find out suitable cultivation methods which met the require of watermelon plants normal and healthy growth through adjusting soil moisture and fertilizer well in the south China environment, where was droughty in winter, spring and autumn but rainy in summer. The results showed that the best effect was gained by covering 100 cm wide black film on the furrow under the same cultivation method, and it had good water holding and water-proof effects in the droughty or rainy climate after planting, meanwhile it could increase the utilization rate of fertilizer and improve the yield and quality obviously, so it could be recommended as a suitable open field cultivation method of watermelon in the south China where was rainy in summer and droughty in winter, spring and autumn.
