甘蓝型双低油菜品种,在综合高产栽培技术的基础上,抽薹前1周或摘薹后每公顷追施薹肥尿素112.4kg,当主茎伸长30cm左右时,摘去主茎12～15cm,每公顷可采摘3386.18～4687.50kg的菜薹作蔬菜用,然后使油菜正常成熟每公顷可收获油菜子2604.90～2772.15kg。且摘薹处理比不摘薹的处理菜子增产4.55%～7.32%。抽薹前1周追施薹肥和摘薹后追施薹肥的在扣除成本后分别较施薹肥不摘薹每公顷净增收入7466.60元和5187.54元,分别增115.01%和82.95%,实现了菜薹、菜子双丰收,取得了显著的经济效益。
Based on the comprehensive high-yielding cultivation techniques, 112.4kg urea was topdressing 1 hectare of semen fertilizer per hectare for 1 week before bolting and 12-15 cm when the main stem was about 30cm long. Can be picked per hectare 3386.18 ~ 4687.50kg of vegetable sprouts for vegetables, and then rape normal maturity can be harvested per canola rape 2604.90 ~ 2772.15kg. The bolting treatments increased 4.55% ~ 7.32% more than the treatments without bolting. 1 week before bolting topdressing sedge fertilizer and seized after sprouting sedge fertilizer after deducting costs respectively than sprouting fertilizer seeding per hectare net income 7466.60 yuan and 5187.54 yuan, respectively, by 115.01% and 82.95%, to achieve Vegetable sprouts, double crop harvest, and achieved significant economic benefits.
