利用塑料大棚栽培蔬菜具有对气候条件的依赖性小、可调节蔬菜供应时间等优点,各地发展较快.但由于大棚栽培与露地栽培条件有所不同,若栽培管理技术跟不上,或连年栽培和不合理的施肥、灌溉,会导致蔬菜生长发育产生多种障碍.根据我们近几年的调查和研究,大棚蔬菜盐害是主要危害之一,目前一些地方已比较严重,尤其是杭州市郊等地发展大棚栽培较早的地区对一些抗盐力差的蔬菜如黄瓜等,大棚栽培已相当困难,应引起菜农及有关部门重视。
The use of plastic greenhouse cultivation of vegetables has the advantages of small dependence on climatic conditions, adjustable vegetable supply time, rapid development around the However, due to greenhouse cultivation and open field cultivation conditions are different, if the cultivation and management techniques can not keep up, or even years of cultivation And unreasonable fertilization, irrigation, will lead to a variety of vegetable growth and development obstacles.According to our investigation and research in recent years, the greenhouse salt is one of the major hazards of vegetables, at present some places have been more serious, especially in Hangzhou suburbs, etc. The development of greenhouse cultivation earlier areas for some poor salt resistance of vegetables such as cucumber, greenhouse cultivation has been quite difficult, should cause vegetable farmers and relevant departments attention.
