虹桥园艺场是专门生产供应宾馆蔬莱的单位.为了满足市场需要,提高经济效益,我们借鉴杭州、苏州、南京等地的成功经验,在园艺场新址发展22亩无土栽培.经过几年实践,有以下几点体会:一、选定栽培模式无土栽培究竟选择哪一种模式最为理想,我们曾经历了一个探索过程.1992年春,学习苏州虎丘乡花锦园艺场的经验,曾在园艺场旧址建了4个中棚的营养液膜栽培设施.当年定植美芹,由于气温适宜,长势良好.但到第二年,遇夏季高温和冬季低温,长势均不理想.看来,在无温控条件的中棚内,营养液膜栽培难以周年生产.后来,也曾考虑过基质栽培.但上海近郊基质来源很困难,而且需要定期更换、消毒,工作量很大,因而也不能采用.最后,在学习浙江省农科院经验的基础上,结合本场的实际,采用了结构简单、适用性广、管理方便、投资较省的深水栽培模式.
Hongqiao Horticultural Field is specialized in producing and supplying hotels and restaurants. In order to meet the market needs and improve economic efficiency, we learn from the successful experience of Hangzhou, Suzhou, Nanjing and other places to develop 22 acres of soilless cultivation in the new horticultural site. After several years of practice , The following experience: First, the selected cultivation mode Soilless culture exactly what kind of model to choose the most ideal, we have experienced a process of exploration .1992 spring, Suzhou Huqiu Township Flower Jin Horticultural experience, Horticultural site built in the middle of four shed nutrition liquid film cultivation .Centennial planted celery, due to the appropriate temperature, good growth.But the second year, the case of high summer temperatures and winter temperatures, the growth is not ideal.It seems that in the In the greenhouse with no temperature control conditions, it is difficult to produce annual nutrition liquid film culture. Later, the substrate cultivation was also considered. However, the matrix source of the suburbs of Shanghai is very difficult to be replaced and disinfected regularly, so it can not be used Finally, based on the experience of Zhejiang Academy of Agricultural Sciences, combined with the actual situation in this field, a deep - water cultivation mode with simple structure, wide applicability, convenient management and less investment is adopted.
