Problems solved by technology

[0002] The construction of submerged plant systems in the current water ecological restoration technology is limited by the background conditions of the water body. Hard-bottomed water bodies, excessive flow velocity erosion, excessive sedimentation, excessive pollution load, high water level and low transparency are all conditions that limit the planting of submerged plants. ; It is difficult for traditional aquatic planting beds to solve the problems of high-velocity scouring and bottom-fitting and tiling, and it is also difficult to maintain a high survival rate in high-load polluted water or high-load polluted silt; , or under soil conditions
Most of the existing submerged grass blankets have a single fiber structure, single utility, low plant survival rate, and many restrictions. It is difficult to scale production and application, and it is difficult to subvert the traditional submerged plant planting mode. The application prospect is small

Abstract

The invention relates to the technical field of submerged planting, and provides a composite planting carrier, a preparation method and application and a submerged grass blanket. The composite planting carrier comprises the following components in percentage by mass: 15-18% of plant fibers; 60-68% of high-molecular polymer fiber; 5-10% of a slow release agent; 1-2% of a foaming agent; 1-2% of a low-melting-point auxiliary agent; and 10-12% of an adsorbent. The preparation method comprises the following steps: carding plant fibers and high-molecular polymer fibers, spreading, knitting, carrying out hot air setting, carrying out cold air setting, dipping in an aqueous solution containing an adsorbent, drying, and adding a slow-release agent, a foaming agent and a low-melting-point additive during spreading. The submerged plant blanket comprises the composite planting carrier and submerged plants. According to the method, the submerged plants can be cultivated and grow on the composite planting bearing body in an expanding mode without the soil matrix condition, and the high survival rate of the submerged plants in high-load polluted water or high-load polluted sludge is kept.

Description

technical field [0001] The invention relates to the technical field of submerged planting, in particular to a composite planting carrier, a preparation method and application, and a submerged grass blanket. Background technique [0002] The construction of submerged plant systems in the current water ecological restoration technology is limited by the background conditions of the water body. ; The traditional aquatic planting bed is difficult to solve the problems of high flow rate scouring and underwater fitting and tiling, and it is also difficult to maintain a high survival rate in high-load polluted water or high-load polluted sludge; in addition, submerged plant seedlings can only be expanded in ponds. , or under soil conditions. Most of the existing submerged grass blankets have a single fiber structure, single utility, low plant survival rate, many restricted conditions, difficult to large-scale production and application, difficult to subvert the traditional submerg...
