Technical Field

The invention belongs to the technical field of greening construction, and particularly relates to a local turf management device based on greening construction.

Background

Turf is an artificially cultivated green plant laid on stadiums, football fields, plazas, and the like. The grass shoveled down with a thin layer of clay is used for laying lawn to beautify environment or laying on the surface of the bank to prevent scouring. The turf type is 75% fine leaf grass and 25% big leaf grass. The turf of the world cup court is a kind of 'synthetic' turf, namely different natural turf is artificially synthesized according to an expert formula, wherein about 70 percent of the turf is the grass in the shape of the panicle, and about 30 percent of the turf is the pasture. In 2006, turf required for the world cup court was partially cultivated in damstatt, local in germany, and partially cultivated in haitsen, the netherlands.

Application No.: the invention discloses a municipal greening construction device which comprises a liquid medicine box body, wherein an opening is formed in the upper end of the liquid medicine box body, a liquid inlet mechanism is arranged in the opening, a strap mechanism is fixedly connected to the side wall of one end of the liquid medicine box body, a first through hole which is communicated with the inside and the outside is formed in the lower end of the liquid medicine box body, a first telescopic hose which is communicated with the through hole is fixedly connected to the lower end of the liquid medicine box body, a grabbing mechanism is fixedly connected to one end, far away from the liquid medicine box body, of the first telescopic hose, the grabbing mechanism is communicated with the first telescopic hose, and a pressing mechanism is fixedly connected to the lower end of the grabbing mechanism.
