矮化密植苹果树节水灌溉研究
Study on Water-saving Irrigation of Compact Shortened Apple Tree
摘要
Abstract
[Objective] To improve the irrigation water use efficiency of fruit trees in Beijing,and provide basis for the design and application of trace irrigation system.[Method] Through laboratory experiment and field application,the effects of different irrigation amount on irrigating dwarfing close planting apple trees were compared.[Result] The ratio of vertical wetting front to horizontal wetting front increased with the growth of irrigation time.The soil water content at different depths showed the law of increasing first,then decreasing and then increasing.The law of soil water content in the same layers was that the irrigation quota for 12 L/h treatment (H1) was higher than the irrigation quota of 10 L/h (H2).The height growth of H1 was larger,the growth of base diameter and crown width of H2 was larger.[Conclusion] When the amount of irrigation decrease by 20%,growth of trees will not be affected as well as to achieve water-saving irrigation purposes.关键词
