在栽甘薯时,上部只留3—4片叶,其余叶子全部栽入土中,缓苗快,成活率高。因此,有经验的栽秧手都是一手拿苗,另一手把下部几片叶缠到茎上,栽入土内,叫做“握叶”。凡这样栽的,都表现增产。但因“握叶”栽的慢,又麻烦,在生产上不易推广。 In planted sweet potato, the upper left only 3-4 leaves, the remaining leaves all planted in the soil, Huanmiao fast, high survival rate. Therefore, the experienced seedlings are hand holding seedlings, the other hand the lower part of a few leaves wrapped around the stem, planted in the soil, called “hold the leaf.” Where planted, have shown increased production. But because of “slow leaf” planted, and trouble, difficult to promote in production.
