苹果已发展成为庆阳地区农村经济的一个重要支柱产业 ,而制约该区苹果发展的主要自然因素是水资源匮乏。试验结果表明 ,盛果期苹果树实行果园覆膜、覆草免耕覆盖集水技术 ,可以有效地利用天然降水 ,减少土壤蒸发 ,不必灌溉或少量灌溉就能维持全生育期生长、结果的水分需要 ,既节约了灌溉用水与中耕除草投资 ,又改善了果树生长的微生态环境 ,可促进果树生长 ,提高产量和质量 ,是北方干旱果园实行农艺节水栽培行之有效的措施 Apple has developed into an important pillar industry in Qingyang rural economy. The main natural factor restricting the development of apples in this area is the lack of water resources. The experimental results show that apple trees in orchard full bloom fruit orchard mulching no-tillage cover catchment technology can effectively use natural precipitation, reduce soil evaporation, irrigation without irrigation or a small amount of irrigation can maintain the growth during the whole growth period, the results of the water It is necessary to save investment in irrigation and cultivation and weeding, and improve the micro-ecological environment for the growth of fruit trees, which can promote the growth of fruit trees and increase the yield and quality, which is an effective measure to implement water-saving farming in the northern arid orchards
