利用塑料大棚黄瓜定植前空闲时间移植甘蓝苗,具有成本低、缩短苗龄、扩大幼苗营养面积、便于集中管理等优点。 1.适期播种:塑料大棚光照、肥水条件较好,昼夜温差大,秧苗生长较快。1月下旬～2月初于温室播种,苗龄为60天左右。 2.适时扣棚:为了提高棚内温度,2月末～3月初扣棚为好,为便于后期放风等管理以覆盖4大扇为宜。扣棚后,应准备保温措施,如遇寒潮可进行小棚覆盖、挂天幕或设围裙。然后,平整床土做成1米宽的菜畦。
The use of plastic greenhouses before planting cucumbers free time transplanting cabbage seedlings, with low cost, shorten seedling age, expand seedling nutrient area, easy to centralized management and so on. 1. Sowing: plastic greenhouse lighting, fertilizer and water conditions are good, large temperature difference between day and night, seedlings grow faster. In late January ~ early February planting in the greenhouse, seedling age of about 60 days. 2 timely deduction shed: In order to improve shed temperature, the end of February ~ early March buckle as well, in order to facilitate post-wind and other management to cover 4 large fan is appropriate. After deduction shed, should be prepared for insulation measures, in case of cold sheds can be covered shed, hanging curtain or apron. Then, the flat bed made of 1 meter wide dishes.
