Experiment and Application of Integrated Water and Fertilizer Technology for Corn Drip Irrigation under Plastic Film in Fenhe Irrigation District
In the Fenhe Irrigation District,the application test of drip irrigation water and fertilizer integration technology under the condition of maize mulching was carried out with the traditional surface irrigation without mulching maize as a contrast.The experiment compared the growth dynamics,water consumption,and water consumption patterns of corn under two modes,as well as irrigation,fertilization,yield,and economic benefits.The results show that the water consumption patterns of drip irrigation corn under plastic film are basically the same as that of ground irrigation corn without plastic film,but the daily average water consumption is lower than that of corn without plastic film,and it has significant water-saving,fertilizer-saving,efficiency improvement,yield increase,and income increase effects.The method for determining the irrigation quota was proposed,as well as the irrigation scheduling and fertilizer regime of integrated water and fertilizer technology for corn drip irrigation,which can provide reference for agricultural production practices in Fenhe Irrigation District and other areas in our province with similar conditions.
