不同颜色地膜覆盖对甘薯产量和品质的影响
发布时间：2021-04-18 03:16
2018年和2019年广东海洋大学农学院试验地进行了田间试验,研究了不同颜色地膜覆盖对甘薯广薯87号和普薯32两个甘薯品种水热特性和产量品质的影响。试验设计为2x3因子。使用的塑料薄膜是:（I）黑色;（Ii）银色;（Iii）白色。每个治疗重复两次。广薯87和普薯32是广东省主栽品种。分别在移栽后30、60d和采收期记录主藤长（cm）和藤重的生长参数。移栽后四周记录叶温和地温,每周记录一次。收获期测定单株块茎数、总块茎重（Kg）、块茎粗（cm）、块茎长（Cm）、单果重（Kg）、块茎干物质含量（%）、块茎大小分级、虫害、象甲危害、总果产量（吨ha-1）、胡萝卜素和可溶性物质含量。结果表明:1.所有地膜覆盖材料的生长发育、产量、水热特性和品质性状均显著高于对照或不覆盖。2.在所有处理中,银覆盖处理的产量显著高于对照。普薯32号银质地膜的平均产量为18.65t/ha,其次是黑色地膜（16.51t/ha）和白色地膜（16.31t/ha）,而不覆盖的平均块茎产量最低（12.15t/ha）。3.银膜的块根地下害虫危害最低,其次是黑膜和白膜,所有地膜覆盖均优于对照。4.白膜覆盖普薯32号胡萝卜素含量最...
