根据扬州地区夏季气候特点和小青菜生长习性,按照无公害生产的要求,设计了一套无纺布作基质高效设施立体水培系统。经栽培试验,从品种的选择、播种量与播种方法、出苗至采收阶段日常温度管理、水肥运筹、病虫害防治,以及采收等各个环节摸索出了适合该栽培系统的栽培技术,以期为夏季高温时期设施大棚高效利用、生产多茬安全优质的小青菜提供技术支撑。
According to the characteristics of summer climate in Yangzhou and the growth habits of small vegetables, a non-woven fabric was designed as a three-dimensional hydroponic system of matrix-efficient facilities according to the requirements of pollution-free production. After cultivation experiments, the cultivation techniques suitable for the cultivation system were explored from various aspects such as variety selection, sowing rate and sowing method, daily temperature control from emergence to harvest stage, water and fertilizer operation, pest and disease control and harvesting, High-temperature facilities, efficient use of greenhouse, the production of more safety and quality of small cabbage to provide technical support.
