A greenhouse cucumber drip irrigation under mulch parameter collaborative optimization cultivation method

Abstract

The invention relates to the technical field of water-saving irrigation in protected agriculture and off-season vegetable cultivation, and discloses a coordinated optimization cultivation method for film-mulched drip-irrigated greenhouse cucumbers, comprising a cucumber cultivation technology investigation, a micro-irrigation system objective-function design, and an optimization of film-mulched micro-irrigation technology, wherein: the cucumber cultivation technology investigation includes determining the cultivation season, land selection and fertilization, pruning and vine-training, and harvesting; the micro-irrigation system objective-function design includes constructing and solving a geometric programming model of micro-irrigation parameters; the optimization of film-mulched micro-irrigation technology includes formulating the mulching method, configuring the micro-irrigation system, and conducting field management. The invention has the advantages of high irrigation-water use efficiency, reasonable control of humidity inside the greenhouse, reduced incidence of diseases, simple agronomic operation procedures, and low cost.
