摘要
阐述了苹果园生产中工程节水、生物节水、农艺节水等减蒸降耗节水技术。对苹果园适时、适量、适位灌溉和降低果园蒸散量的"三适一降"农艺节水技术进行了说明。据此进行苹果园水分管理,可以在保证苹果高产、优质的前提下减少无效蒸发,降低奢侈蒸腾,提高灌溉水和降水利用率。
The water-saving techniques with reduced transpiration and water consumption in the production of apple orchards was expounded.The techniques of when,where,how much to irrigate,and how to reduce the water consumption was described.The water-saving techniques with reduced transpiration and water consumption for apple orchards could maximize reduced invalid evaporation and extravagant transpiration and improve utilization efficiency of irrigation water and rainfall in water management of apple orchards under the premise of ensuring high yield and quality of apple fruits.
