北线蔗区甘蔗营养块育苗移栽技术研究

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。

A study on sugarcane nursing and transplanting with nutrient block

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.
