Gathers flows the separation formula irrigation is a new water-saving irrigation pattern, which is based on the characteristic and request that thinly plants the fruit-growing class industrial crop needs water and is proposed on the basis of innovation technical experiment and practice in recent years. This paper summarized the basic idea of gathers flows the separation formula irrigation pattern, elaborated the key technologies of gathers flows the irrigation system, and that is gathers flows the separation formula douche, analyzed the comprehensive technical effect of gathers flows the separation formula irrigation pattern, including saving water to increase production, conserving energy and consumption, raising irrigation water temperature and solving the problem of irrigation unlevelness in low head conditions and pointed out the main problems which should be focused in future.
