覆盖材料对薯棉连作栽培模式产量和品质的影响

Study on the effect of mulch material on the yield and quality of continuous cropping pattern of potato and cotton

在马铃薯-棉花连作栽培模式中分别使用黑色地膜、黑色地膜+稻草、白色地膜、白色地膜+稻草4个不同覆盖材料组合进行试验比较,通过分析不同覆盖材料组合对马铃薯和棉花农艺性状、商品性状及产量性状的影响,综合分析不同覆盖材料组合薯-棉连作栽培模式的经济效益、生态效益和社会效益。结果表明,黑色地膜+稻草覆盖材料组合在改善马铃薯生长环境,提高马铃薯产量和品质,种植马铃薯后改善棉花种植土壤理化指标,提高棉花纤维品质,提高棉花产量方面,优势较明显。

Four different mulch material combinations including black plastic film,black plastic film+straw,white plastic film and white plastic film+straw were used in the potato-cotton continuous cropping mode for experimental comparison.By analyzing the ef⁃fects of four different mulch material combinations on the agronomic traits,commercial traits and yield traits of potato and cotton were analyzed,and the economic,ecological and social benefits of the potato+cotton continuous cropping mode with different mulch materi⁃al combinations were comprehensively analyzed.The results showed that the combination of black mulch+straw had obvious advantages in improving the growth environment of potato,increasing the yield and quality of potato,improving the physical and chemical indexes of cotton planting soil,improving the fiber quality of cotton and increasing the yield of cotton.
