摘要
通过利用甘薯的无性繁殖特性和薯蔓无限生长的能力,在2月初采用人工加温方法,使甘薯提早出苗,并通过温床、地膜覆盖栽培等途径,尽量多繁苗。充分利用5～10月有利薯块膨大的生长季节,尽量早插薯、多插薯,进行春薯、夏薯、秋薯的高产栽培,使甘薯良种的繁殖系数达到20000倍以上。
Utilizing asexual propagation characteristic of sweet potato and infinite growth ability of sweet potato vine, seedlings of sweet potato were emerged earlier by using artificial beating condition in the beginning of February, and using hot bed and film mulching to breed seedlings as more as possible. Making full use of favorable to enlargement of sweet potato＇s block in growing season from May to October, while intercalation as soon as possible and as more as possible. The propagation coefficient of improved sweet potato variety could increase more than 20 000 times as before by high-yield cultivation of sweet potato in spring, summer and autumn.
