The time, place and surface type of each observation are as follows: Cumin land near sample e (barley land) on June 6, 2008; On June 11, 2008, quadrat D (alfalfa field) and quadrat e (barley field); On June 15, 2008, quadrat D (alfalfa field) and quadrat e (barley field); Sample e (barley field) on June 16, 2008 Sample a (reed land) on June 20, 2008 Sample B (saline alkali land) on June 22, 2008 June 23, 2008 sample D (alfalfa land) sample e (barley land) June 24, 2008 sample B (saline alkali land) June 29, 2008 sample a (reed land) sample e (barley land) This data set includes 14 optical quantum meter measurement data excel tables, a word document of original data description and a TXT document of data problem record.
