1975年春,红岩队在0.04亩的地上,用47株湖桑苗边定植边压条,当年秋天就繁育出圃湖桑苗321株。去年春天仍用这47株湖桑苗继续压条,秋后又繁育出圃632株桑苗,繁育系数为13.4倍。在两年中,用47株湖桑苗,共繁育953株桑苗,并采摘苗叶141.9斤。一、好处采用以苗育苗的办法,用1株桑苗当年就能育成7株,第二年为13.4株,第三、四年还会增多,比袋接法和插条法繁育速度快;技术简单,容易掌握,不要砧木、接穗和嫁接;这种方法比袋接法省工三分之一,省地二分之一,省肥一半
The spring of 1975, Hongyan team in the 0.04 acres of land, with 47 strains of Sang Miao edge planting side battens, then bred in the autumn Lake 321 seedlings Lake. Last spring still use the 47 strains of Sang Miao continue pressing, bred again autumn after the nursery 632 mulberry seedlings, breeding coefficient of 13.4 times. In two years, with 47 strains of Lake Sang, a total of 953 plants were bred, and picked 141.9 kg of seedlings. First, the benefits of seedlings to adopt the method of seedlings, with a mulberry seedlings that year will be able to bred 7, the second year of 13.4 strains, the third and fourth years will increase more than bags and cuttings lawbreeding speed; Technology is simple, easy to grasp, do not rootstocks, scion and grafting; this method is one-third of provincial labor than bag connection, one-half province, half fertilizer
