TY - Data T1 - Data on cation exchange capacity of Sandy and salinized saline soil, continuous cropping of cotton field, land improvement and ecological management in Alar oasis, Xinjiang (2017-2018) A1 - He zhibin A1 - None A1 - None DO - 10.12072/ncdc.STXF.db0004.2021 PY - 2021 DA - 2021-10-22 PB - National Cryosphere Desert Data Center AB - The cation exchange capacity of different types of saline soils includes the data of soil base ions and soil cation exchange capacity of different types of saline soils in the middle and upper reaches of Tarim River in Aksu area, Xinjiang. Salinized soil data (organic matter and eight ions) include total salt of salinized soil and pH of salinized soil; Water extraction germination potential was set up in continuous cropping obstacle elimination test; Water extraction - germination rate; Water extraction - seedling length; Water extraction - plant height; Water extract - blank. The data were collected from 2017 to 2018 at alar and Tarim rivers in Xinjiang. The data set carries out relevant tests, observations and data collection in strict accordance with the unified test scheme formulated by the subject and the specifications for water, soil and gas generation observation of terrestrial ecosystem compiled by China ecosystem research network. Excel and SPSS are used for data input, processing and calculation. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/c631e508-b798-492c-b379-fe86f36c2b89 ER -
