AB  - This data set was collected in test area 5 on June 14, 2012 × Crop Phenology and field management survey data carried out near 13 vortex stations in 5km. 1.1 purpose of investigation Provide supporting data sets for eddy, meteorological and biophysical parameter tests. 1.2 investigation location and content Survey locations: Shiqiao No. 9 community (EC3), Xiaoman South Street (ec16), five star No. 5 community (ec13), Xiaoman No. 5 community (ec14), Shiqiao No. 2 community (EC5), Zhonghua No. 6 community (ec11), Shiqiao No. 6 community (EC2), ec6, Jincheng No. 5 community (EC7), Jincheng No. 6 community (EC8), Corning No. 1 Community (ec9), Corning No. 2 community (EC10) and Jincheng No. 4 community (ec12). The investigated crop type is seed maize, and the investigation content includes two parts: Crop Phenology and field management. The crop phenological data includes crop type, variety, sowing date, sowing method, plant spacing, row spacing, ridge direction, field area, seedling emergence period, three leaf period, seven leaf period, etc. the field management data includes tillage time, tillage time, irrigation time, irrigation amount, fertilization time, fertilization type, fertilization amount, etc. 1.3 investigation method The survey adopts the household by household survey method. The owner of the pre investigated field is found on site. According to the pre-designed survey content, a questionnaire survey on the phenological characteristics of crops in the field and field management methods is carried out. For the organization and format of Crop Phenology and field management survey data, see "description document of Crop Phenology and field management survey data". The file format of the data is Excel 2007. The data files include Heihe comprehensive remote sensing joint test: Crop Phenology survey data in the ecological and hydrological test area of the middle reaches of the artificial oasis.
