Effect of Drip Irrigation and Micro-sprinkler Irrigation on Water Consumption,Yields and Quality of Walnut

Field experiment was conducted to study the effect of drip irrigation and micro-sprinkler irrigation on Water Consumption,Yields and Quality of aged Walnut trees,which used the same irrigation schedule.The experiment results showed:①Under the condition of drip irrigation,the average of daily water consumption in blooming stage,fruit accelerated growth stage crust stage and maturity stage were 2.9mm,3.97mm,5.55mm and 3.39mm respectively.Water consumption of micro-sprinkler irrigation was different from drip irrigation,but in fruit accelerated growth stage and maturity stage the cumulation of water consumption of Both irrigations had no difference.②The water use efficiency of drip irrigation was about 15% higher than micro-sprinkler irrigation.The yield of drip irrigation was higher than that of sprinkler irrigation.③Under the condition of two Irrigation methods,the content of protein of drip irrigation was higher than micro-sprinkler irrigation and as same as the ratio of bared kernel.Other indexes made no difference.
