以黑皮果蔗茎尖脱毒组培杯苗为材料,比较不同种植密度、主茎苗不同去除时间对生产商品蔗的影响,结果表明,脱毒果蔗组培苗在分蘖盛期拔节初期进行间苗,并去除主茎苗,定苗5.175万株.hm-2,可显著提高产量和商品蔗率;果蔗茎尖脱毒健康组培杯苗种植密度1.5万～1.8万株.hm-2,在苗间、去除主茎苗、定苗及在相应技术配套条件下进行商品蔗生产,经济效益高。
The effects of different planting density and different removal time of main stem seedlings on the production of commercial sugarcane were compared with the tips of dendrantimic cortex tip of black sugarcane cane. The results showed that during the initial stages of jointing, Mung bean seedlings, and remove the main stem seedling, Dingmiao 5.175 million.hm-2, can significantly increase the yield and commodity sugarcane rate; cotyledon shoot tip detoxification healthy tissue culture cup seedlings density 15000 ~ 18000.hm-2 , In the seedling, remove the main stem seedlings, Dingmiao and the corresponding technical conditions for the production of commercial cane production, high economic efficiency.
