Economic crop belt for cutting down pollutants in ditch in irrigated region

Abstract

The invention provides an economic crop belt for cutting down pollutants in a ditch in an irrigated region. The economic crop belt comprises an economic crop growing region, a vertical weight lifting repair region, a transitional spacer region and fixing piles, wherein the economic crop growing region is connected with the vertical weight lifting repair region through the transitional spacer region, and the fixing piles are used for fixing the economic crop growing region, the vertical weight lifting repair region and the transitional spacer region at designated spots on one side of the ditch. According to the economic crop belt, organic pollutants and nutritive salt in farmland tail water are removed through assimilation and absorption as well as adsorption and consumption of water planting economic crops and light ceramic particles in the economic crop growing region as well as biozeolite in the vertical weight lifting repair region, the plants growing in the economic crop belt has economic benefits while giving play to ecological benefits simultaneously, the maintaining enthusiasm of farmers can be strengthened, and the generalization performance is strong. During the irrigation period, the device can be put away and put on the ditch to guarantee the water flow speed of the ditch, has the advantages of being low in cost, simple and attractive, economical and environment-friendly, and obvious in effect, and is suitable for cutting down the pollutants on a farmland surface source.

Description

technical field [0001] The invention explores a method for controlling agricultural non-point source pollution by constructing a economic crop belt for reducing pollutants in ditches in agricultural irrigation areas. Background technique [0002] With the development of society and economy, human activities have gradually increased, and water pollution problems such as organic pollution, oil pollution, and eutrophication have become increasingly prominent. As one of the most important sources of water pollution, agricultural non-point source pollution has become the focus of water environmental pollution control. question. In recent years, units at all levels have actively responded to the spirit of the central government's instructions on the prevention and control of agricultural non-point source pollution, and have taken many measures to control non-point source pollution. Ditches in agricultural irrigation areas are transitional areas that receive non-point source pollu...

Problems solved by technology

However, most of these methods are ecological restoration devices for the ditches themselves. The devices are immovable, and the installation and later maintenance are troublesome. During the irrigation period, the water passing rate may be affected, and it is difficult to mobilize farmers' enthusiasm for maintenance.
