2022-11-22 Study on the change of winter wheat crop coefficient and its influencing factors in the taihang piedmont plain of luancheng experimental station from 1980 to 2020 doi:10.57760/sciencedb.06573 en 1. Test name: Research database of crop coefficient change and influencing factors of winter wheat in Taihang piedmont plain for 40 years from 1980 to 20202. Data collectors: Zhang Xiying, Li Haotian, Li Lu, Yan Zongzheng, Gao Congshuai3. Test data year: 1980-20204. Test site: Luancheng Agricultural Ecosystem Test Station, Chinese Academy of Sciences (37 ° 50 ′ N, 114 ° 40 ′ E, altitude 50.1m)5. Research objectives:(1) Crop coefficient is a basic parameter for calculating crop water demand. Accurate determination of crop coefficient plays an important role in optimizing irrigation management.(2) Crop coefficient changes with crop growth and environmental conditions. Studying how crop coefficient is affected by changes in production conditions and meteorological conditions can provide a basis for accurate determination of crop coefficient.
