摘要
试验表明,采用电热线温床扦插,在2月下旬剪取插穗,穗长18厘米,直径1.1厘米以上。插前穗基用150ppmNHM激素浸渍20—24小时。扦插密度每平方米2000株,插床温度27℃,气温12℃,每天喷水一次,(1.75公斤/米~2)。本地区扦插适期为3月上旬,插穗发根率达95％左右,插后1个月移栽,成活率60—70％。每扦插一株所花材料和电费为0.013元。
Having been treated with 150ppm of NHM hormone for 20 ?24 hrs ,the mulberry wood cuttings, 18cm in length and above 1. 1cm in diameter,cutted in the late February were cultured in the warm bed with heating wire under the conditions of 27℃ in the bed and 12℃ at atmosphere. The density was about 2 000 cuttings per squire metre and the 1. 75 kg of water was necessarily sprayed every day. The result showed that the root germinating rate was about 95%,the surviving rate of transplant was 60-70% after cutting for one month and the optimal cutting period was in early March in Suzhou area.
