摘要：
For a long time, the soil of artificial forest land in the loess hilly-gully region was continued to be dry, which had serious impact on the subsequent vegetation. Studying on jujube growth in the dry soil had important significance to realize forestry sustainable development in this region. Four different initial soil volumetric water content levels were set for the experiment in the open air, and the same water-saving type pruning was used to keep consistent specifications. Soil moisture, jujube growth and yield for two consecutive years were tested under a completely natural rainfall condition. Results showed that the soil moisture was tended to be a fixed value for different initial soil moisture contents under natural rainfall. And this value was depended on rainfall. Normal precipitation year soil moisture was steady at (13.83±0.22)% in 2014, partial drought year soil moisture was steady at (9.46±0.32)% in 2015. Different initial soil drying degrees would significantly inhibit the growth of branches and jujube fruit number. Jujube growth under the same dry soil was depended on rainfall. The yield under water-saving type pruning technology was 36%~41% higher than that of conventional dwarf pruning, water use efficiency was increased by more than 3.6 times. Water-saving pruning techniques would improve jujube water use efficiency. This research can solve dry jujube soil water shortage in the loess hilly-gully region and provide new basis for achieving sustainable development. This research had the important theoretical significance and value in practice. © 2017, Chinese Society of Agricultural Machinery. All right reserved.
