| Abstract | This study aimed to analyze the spatial correlation between soil water and root distribution in dense-dwarf jujube plantations in the Hilly Loess Region (HLR) of China. The soil coring method was used to sample roots at different depths within the 0–1,000 cm soil profile. The results showed that increase in average annual root depth decreased with increasing jujube stand age. The maximum root depth of the 12-year-old jujube was 520 cm. The difference between the maximum and minimum root depths in the 12-year-old jujube trees was 180 cm. Lateral roots started developing intersection networks 3 years after planting. Soil water fluctuation was not induced by vertical root systems of dense-dwarf jujube plants. With increasing jujube stand age, root depth, dry soil layer depth (below 240 cm) and annual soil water variance within the top 0–200 cm soil layer increased. However, root-zone soil water content decreased with increasing stand age while dry soil layer depth was slightly larger than root depth. The results of this study have important significance to provide vital technical support for jujube cultivation especially under semiarid conditions and were expected to find application in water management for plantations in the HLR. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
