Study On Ebb And Flow Irrigation Technique Of Leafy Vegetables On Balcony

In order to explore the suitable ebb and flow irrigation mode for leafy vegetables in the balcony,the effects of different ebb and flow irrigation modes on the growth,yield and quality of four kinds of leafy vegetables,including lettuce,fast vegetable,rape and mustard were studied by using the ebb and flow irrigation system.According to the morphological,yield,SPAD value and quality index measured by the test,the following conclusions were obtained after comprehensive analysis.(1)When the experimental conditions were as following:irrigation height was 2 cm,hold time was 3 min and irrigation Interval time was 2 h,the form of lettuce and fast vegetable were the best.Irrigation interval time was 6 h,the quality of lettuce and fast vegetable were the best.Comprehensive the yeild and quality,the indicators of lettuce,fast food in irrigation time interval for4 h is more appropriate,in which can achieve a better yield and quality.Therefore,in the actual production can undertake choosing according to the actual demand.(2)In ebb and flow irrigation height is 2 cm of the experimental conditions,the irrigation time interval for 2 h,hold the irrigation time 3 min,the morphology of rape,mustard,yield the best.Irrigation time interval for 4 h,the irrigation time 3 min,rape,mustard quality best,yield is second only to the highest process.Comprehensive indicators,rape,mustard in irrigation time interval for 4h,irrigation time 3 min is relatively appropriate,after obtaining the best quality and higher output.(3)In different irrigation of time interval of treatment,and the growth of lettuce,fast food quality are increased with irrigation interval extension of the first after rising downward trend.The results showed that suitable irrigation time interval is conducive to the growth of lettuc and fast vegetable,biomass accumulation and quality formation.(4)In different irrigation time interval,irrigation under the influence of the processing of time,and the growth of rape,mustard and production are in with the irrigation time interval,the quality is as the extension of irrigation time interval and rise.When dealing with the irrigation time interval,the same irrigation maintenance time is different,rape,mustard,there were no significant differences on the growth and yield of differences in the quality.The results showed that the irrigation maintenance time of 3 min or irrigation,time of 6 min,growth and biomass accumulation of rape,mustard no significant influence,but can affect the quality of rapeseed and mustard.
