Abstract

The invention provides a regulation and control method and device for rice field water volume. The method comprises the following steps: acquiring daily precipitation of a current land parcel in the current year according to historical precipitation data of the current land parcel; determining the leaching amount of the current land parcel according to the total field surface water amount and historical leaching amount data of the current land parcel; according to the daily precipitation amount, the leaching amount and the measurement parameters of the current land parcel, determining the irrigation amount or the water discharge amount of the current land parcel based on the water demand amount of the rice in different growth stages. According to the regulation and control method and device for rice field water volume, timely and accurate regulation and control of the rice field water volume can be achieved, so that water resources are saved while water required by normal growth of rice is guaranteed, and nitrogen and phosphorus non-point source pollution of the rice field can be effectively prevented and controlled.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a method and device for regulating water volume in paddy fields. Background technique [0002] The water consumption of rice accounts for about 60%-70% of the total agricultural water consumption, and the consumption of chemical fertilizers exceeds 20%. Due to the extensive management of water and fertilizer in rice planting, there are common problems such as shallow fertilizer application, excessive base fertilizer and tillering fertilizer, random irrigation and drainage, etc. In addition, the water network in the rice planting area is densely distributed, and the rainfall is abundant, and flood disasters are prone to occur frequently The problem of non-point source pollution of nitrogen and phosphorus caused by rice cultivation cannot be underestimated. [0003] One of the key measures to prevent and control non-point nitrogen and phosphorus pollution in paddy ...
