2018年和2019年廣東海洋大學農(nóng)學院試驗地進行了田間試驗,研究了不同顏色地膜覆蓋對甘薯廣薯87號和普薯32兩個甘薯品種水熱特性和產(chǎn)量品質(zhì)的影響。試驗設計為2x3因子。使用的塑料薄膜是:（I）黑色;（Ii）銀色;（Iii）白色。每個治療重復兩次。廣薯87和普薯32是廣東省主栽品種。分別在移栽后30、60d和采收期記錄主藤長（cm）和藤重的生長參數(shù)。移栽后四周記錄葉溫和地溫,每周記錄一次。收獲期測定單株塊莖數(shù)、總塊莖重（Kg）、塊莖粗（cm）、塊莖長（Cm）、單果重（Kg）、塊莖干物質(zhì)含量（%）、塊莖大小分級、蟲害、象甲危害、總果產(chǎn)量（噸ha-1）、胡蘿卜素和可溶性物質(zhì)含量。結果表明:1.所有地膜覆蓋材料的生長發(fā)育、產(chǎn)量、水熱特性和品質(zhì)性狀均顯著高于對照或不覆蓋。2.在所有處理中,銀覆蓋處理的產(chǎn)量顯著高于對照。普薯32號銀質(zhì)地膜的平均產(chǎn)量為18.65t/ha,其次是黑色地膜（16.51t/ha）和白色地膜（16.31t/ha）,而不覆蓋的平均塊莖產(chǎn)量最低（12.15t/ha）。3.銀膜的塊根地下害蟲危害最低,其次是黑膜和白膜,所有地膜覆蓋均優(yōu)于對照。4.白膜覆蓋普薯32號胡蘿卜素含量最...
