在蔬菜种植中,塑料大棚、小棚和地膜覆盖栽培是一项新的保护地栽培技术。历年来,各种大棚累计总面积为600亩。大棚内套小棚和地膜覆盖栽培的蔬菜品种有黄瓜、番茄、茄子、菜尖椒和豇豆等,为城市供应蔬菜提早上市20～30天,取得显著的经济效益。随着蔬菜塑料大棚覆膜栽培的推广和应用,存在着追施肥水的困难,温湿度引起黄瓜病害,以及早衰等问题,影响了覆膜栽培的经济效益,针对上述问题,我们对塑料大棚覆膜栽培的黄瓜进行小喷灌和泼浇肥水两种方式的对比试验,取得了著的显效果,现将试验结果综述如下:
In the cultivation of vegetables, plastic sheds, sheds and plastic film mulching cultivation is a new protected cultivation techniques. Over the years, all kinds of greenhouses have a total area of 600 mu. Greenhouse covered shed and mulching Cultivated vegetables varieties cucumber, tomato, eggplant, vegetables, pepper and cowpea, vegetables for the city to market early 20 to 30 days, and achieved significant economic benefits. With the popularization and application of plasticized plastic greenhouse planting cultivation, there is the difficulty of fertilizer fertilizers, cucumber diseases caused by temperature and humidity, as well as premature aging and other issues, affecting the economic benefits of film cultivation. In response to the above problems, we covered the plastic shed Membrane culture cucumber small sprinkler irrigation and pouring fertilizer water two ways of comparison test and achieved significant results, the test results are summarized as follows:
