摘要
北线蔗区甘蔗高效低耗营养块育苗移栽技术，必须选在冬季（１１月上旬）或春季（２月下旬）育苗，采用甘蔗上部（蔗梢）作种，选择８ｃｍ见方的营养块规格，且蔗芽要横放，芽朝边，并在３月中旬至４月上旬（５叶）土湿时移栽，裸地移栽必须覆盖地膜保湿，套移于油菜地应适当提前，保证６００００苗／ｈｍ２的主苗数，并在次年进行宿根栽培。
Sugarcane nursing and transplanting with nutrient block is an effective technique of low cost. To applicate it in north area, the following practices had better be taken: (1) Select shoots as seed cane and nutrient block size of 8x8 cm, nurse in the winter (early November) or spring (late February), place seed cane laterally; (2) Transplant to naked land during the period of middle March to early April with film covering, for intercrop, transplant earlier; (3) Control shoot number around 60000/hm 2, cultivate ratoon crop in the second year.
