| Abstract: | A reasonable coefficient of irrigation benefit is the key in computation irrigation benefit when use shared coefficient of irrigation benefit.The experiment of different crops production is taken in middle district of Guizhou province under the condition of local typical hydrology year,in order to determinate the shared coefficient of irrigation benefit of local staple crop,the function of farmland irrigation water in the agricultural production was analysised,and it can provide the scientific basis for the... |
