近年来,我们进行了甘蓝再生栽培试验,获得了成功,第一次采收平均单株1kg按亩栽2500株,亩产2500kg,第二次采收平均单株1.6kg,亩产4000kg,比一季增产37.5％,同时比一季可缩短生长期50～60天,减轻田间劳动强度、降低生产成本,是一项增产增收的有效技术。品种采用早熟平头类型的京丰1号,主要栽培技术如下。 1 严格掌握第一次的采收期根据第一次的适时采收期分期比较,10月下旬最适宜。因此,第一次必需在10月底采收才能满足二次再生的高产。
In recent years, we carried out the regeneration of cabbage cultivation experiments, was a success, the first harvest of an average of 1kg planted acres per acre 2500, mu 2500kg, the second harvest of an average of 1.6kg, mu produce 4000kg, than An increase of 37.5% in the first quarter, while shorter than the first quarter growth period of 50 to 60 days, reduce labor intensity and reduce production costs, is an effective technology to increase production. Varieties using precocious flat type Jingfeng 1, the main cultivation techniques are as follows. A strict grasp of the first harvest According to the first timely harvest period comparison, the most suitable late October. Therefore, the first harvest must be completed by the end of October to meet the high yield of secondary regeneration.
