玉米膜下滴灌在大庆市的发展与推广

Development and Promotion of Cron Growing Using Drip Irrigation under Plastic Membrance in Daqing City

玉米膜下滴灌技术是覆膜种植与滴灌技术的相结合,初步实现了浇水、施肥一体化和可控化,由传统的大水漫灌,转向了浸润式灌溉。膜下滴灌与常规种植方法相比较,节水、节肥、省工、节地、增产、提质、增效。大庆市在气候特点和社会需要等方面很适合发展玉米膜下滴灌。该文在分析玉米膜下滴灌节水、增产机理的基础上,从大庆市的气候条件,现代农业需要和产生的效益等方面论述了大庆市发展玉米膜下滴灌的必要性。虽然其推广中仍存在一定的问题,但膜下滴灌的优势已经显现。

Cron growing using drip irrigation under plastic membrance is the combination of plastic membrance and drip irrigation technology, it has been made the initial realization of watering, fertilization integrated and controlled, the way of irrigation from traditional flood irrigation turned to be immersion irrigation. Comparing with conventional planting methods, drip irrigation under plastic membrance has more obvious effect on water saving, fertilizer saving, labor saving, field saving, improving quality and increasing production of the corn. Cron growing using drip irrigation under plastic membrance is very suitable to developed in the city of Daqing, because of its climate characteristics and social needs. On the basic of analyzing the principle of water-saving and product increasing, according to the climatic conditions in Daqing, the needs and the effectiveness of the modem agricultural, discussing the necessary for the development of drip irrigation of corn under plastic membrance. Although there are still some problems to resolve, the advantages of drip irrigation is obvious.
