Effects of Different Irrigation and Soil Moisture Conversation Treatments on Soil Water Dynamics and Water Consumption in Apricot Orchard

Through four different irrigation and soil moisture conversation treatments:conventional irrigation,drip irrigation,plastic mulched drip irrigation and plastic mulched of regulated drip irrigation on the field experiment of mountainous apricot orchard had carried out.The experiment was to evaluate the effects of these treatments on soil water content,water consumption,water use efficiency and yield of apricot trees.The results showed that,plastic mulched drip irrigation method not only saved the water amount,but also increased water use efficiency.Therefore,plastic mulched drip irrigation treatment was an effective method to keep soil moisture for apricot trees.before the harvest stage,the added irrigation quantity could increase water content.During growth period,compared to the conventional irrigation,the plastic mulched drip irrigation,drip irrigation and plastic mulched of regulated drip irrigation saved water by 49.85%,49.85% and 62.46%,respectively.The plastic mulched drip irrigation treatment of water use efficiency was 7.934 g/m3,which was the highest among four treatments.
