唐山市近郊温室蔬菜生产多以一年两茬为主,即春茬番茄、黄瓜,秋茬黄瓜、番茄或芹菜、韭菜。由于长期重茬种植,病害严重、产量不稳,加之蔬菜种类单调上市集中,如遇销售渠道不畅时往往造成菜贱伤农,影响温室生产的效益。据此,我们在开发南方蔬菜品种的同时,指导农户抓住市场空缺,利用时间差与空间差,优化蔬菜品种配置,进行立体化、多茬次种植,使温室蔬菜生产的年效益稳定在1.5万元左右,受到菜农的普遍欢迎,现介绍于后(文中符号“——”表示接茬,“……”表示间作)。
The suburbs of Tangshan City greenhouse vegetable production and more in a year mainly on two stubbles, that is, spring stubble tomato, cucumber, autumn cucumber, tomato or celery, leek. Due to long-term continuous cropping, serious disease, unstable yield, and monotonous market concentration of vegetables, in case of poor sales channels often result in lower prices and harmed farmers, affecting the benefits of greenhouse production. Therefore, while developing the varieties of southern vegetables, we guide farmers to seize the market vacancies, make use of the difference in time and space, optimize the configuration of vegetables, and implement the three-dimensional and multi-cropping arrangements to stabilize the annual benefit of greenhouse vegetable production at 15,000 Yuan or so, are generally welcomed by vegetable farmers, are now introduced in the post (the symbol “-” said Jie crop, “...” said intercropping).
