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.
