The effects of microsprinkler irrigation combined with reduced phosphorus,potassium fertilizer and topdressing time on growth and development,water use efficiency and quality of wheat were studied. Results showed that stem and tiller number of jointing stage were affected significantly under phosphorus,potassium fertilizer reduced.Watering three times,(wintering water,drawing water and grouting water)and four times(wintering water,drawing water and flowering water and grouting water),50% phosphate fertilizer applied at seeding time and 50% at jointing stage was the highest,improved the ability of dry matter accumulation after flowering,increased the proportion of dry matter of grain after flowering,allocation amount at mature stage was the highest.Compared with the traditional cultivation mode and micro irrigation with normal fertilization,water was irrigated three times and total amount of 1 500 m3/hm2,50% phosphate fertilizer at seeding time and 50% at jointing stage and 70% of normal phosphate and potassium fertilizer amount was not significant under the irrigation mode,the number of ears and grains of yield components had no significant change,but 1 000grain weight increased.Quality indicators were better than the local traditional mode.Therefore,under the condition of drought and water shortage in Shanxi province,it is possible to realize water and fertilizer reduction with the stable yield and improving quality by microsprinkler irrigation.
