大棚蔬菜的生长环境,因覆盖一层塑料薄膜,形成了对蔬菜生长的小气候条件,对水肥的管理需要讲求技术。在气温较低的月份不宜浇水过多,否则不但影响蔬菜的生长,还会引起病害。在天气逐渐转暖,蔬菜进入生长旺期,应适当加大浇水量,否则也会阻碍蔬菜的生长,造成严重减产。为了使大棚蔬菜获得丰产.在浇水技术上应该注 Greenhouse vegetable growth environment, due to cover a layer of plastic film, forming a microclimate on the growth of vegetables, water and fertilizer management requires emphasis on technology. In the lower temperature of the month should not be too much water, otherwise not only affect the growth of vegetables, but also cause disease. Gradually warming up in the weather, vegetables into the growing season, should be appropriate to increase the amount of water, otherwise it will hinder the growth of vegetables, causing serious cuts. In order to make greenhouse vegetables get rich in watering technology should note
