【摘要】 利用条桑灌木带作为母体进行培土繁苗。枝条休眠处理:初冬砍条时留茬12cm,然后培上盖没茬口,秋后单株生根率91.5％,单株发根3.6条,总长度99.9cm;生长期新梢处理:待新梢长至40cm左右时,基部培土15cm,秋后发根率85.6％,单株发根3.2条,总长度61.3cm,苗木栽植成活率85％以上。更多还原

【Abstract】 In mulberry bush belt, the twigs are cut down with stumps 12cm high left and earthed up at the beginning of winter .And in Autumn the rooting rate of the twigs reaches 91 .5%, the total length of 3.6 roots per twig is 99.9cm, Or the twigs are earthed up to 15cm above ground in Summer while they are baout 40cm long.This also gives good results in Autumn: rooting per rate of the twigs more than 95%, the tatal length 3.2roots twig 6.13cm .The experiments demonstrate that the technique mentioned above is econoimic, labour saving and easy for extension.更多还原
