Water control and paddy production technology of rice is to strictly control field moisture according to crop water requirements, accurately grasp the control time and field water control standards, and make limited water resources obtain higher yields. From 1994 to 1998, Lingling Irrigation Experimental Station hosted and promoted 259000 hm2 times in 8 cities and municipality of Hunan Province, saving 30.31% ~ 50.91% and increasing 8.16% ~ 14.3 0% of the effect.
