The invention provides an ecological water replenishment system and a water replenishment method for a rain-source river, comprising a water intake system in a water plant, a water replenishment pipeline system, a comprehensive utilization system for replenishment water and a rainwater storage system. The water intake system of the water plant includes a parallel overflow well water outlet system and a gate well water outlet system; the comprehensive water replenishment utilization system includes four water utilization methods, including water replenishment ports in the upper reaches of the river, artificial wetlands, small lakes and ponds, and reserved later water replenishment interfaces. The final outlet water from the constructed wetland and small lakes and ponds is connected to the river through pipelines, and the water replenishment pipe network and small lakes and ponds respectively have reserved water replenishment interfaces for the later stage. The outlet pipe network of the water replenishment pipe system adopts the layout method that the main system forms a ring pipe, and the branch system adopts a branch pipe network to flow into each outlet. The rainwater storage system includes a rainwater storage module, and the rainwater flows through the sedimentation and abandonment well to the rainwater storage module. The technical solution of the present invention can not only realize water replenishment in the basin, but also improve the abundance of running water in the basin and the clear water quality up to the standard according to different situations. Effect.

The invention discloses a method for improving the survival rate of plants transplanted in winter, which comprises a subsoil layer, a first wet garbage layer, a perlite layer, a greening planting soil layer and a second wet garbage layer successively laid in a planting hole, wherein the first wet garbage layer At least one layer of the garbage layer and the second wet garbage layer is the primary fermented product of wet garbage; the soil balls at the roots of transplanted plants are located in the greening planting soil layer above the perlite layer. Preferably, the first wet garbage layer is wet garbage primary fermentation product, and the second wet garbage layer is wet garbage granules. The primary fermentation of wet garbage is obtained by crushing wet garbage and fermenting for 10-15 days, with a particle size of <1cm; wet garbage granules are granules obtained by dehydrating, drying and compressing wet garbage after secondary fermentation. By using wet garbage, the internal temperature of the soil can be increased, the root system of the plant can be protected, and after degradation, it can be used as a slow-release fertilizer for transplanted trees, improving the survival rate of plants transplanted in winter.

The invention relates to a water bottle cap with a water sealing structure, which comprises a body, a compression bar device, an elasticity device and a water sealing piece, wherein the top of the body is provided with a water outlet hole and an installation cylinder with an accommodation cavity, and the bottom of the installation cylinder is provided with an opening; the compression bar device comprises a compression bar, and one end of the compression bar is movably connected at the body; the elasticity device comprises a rod body, a first elastic piece and a second elastic piece, and the rod body is vertically arranged in the accommodation cavity in a moving way; the rod body is positioned below the compression bar, and the first elastic piece is arranged between the compression bar andthe rod body; the second elastic piece is arranged between the opening at the bottom of the accommodation cavity and the top of the rod body, and the lower end of the rod body protrudes out of the opening; the water sealing piece is arranged below the top of the body, and one end of the water sealing piece is provided with a water sealing part; the other end of the water sealing piece is connected with the top of the body, and the middle part of the water sealing piece is connected with the lower end of the rod body. The invention utilizes the first elastic piece and the second elastic pieceto realize water outlet and water sealing control by a two-stage type stroke, and the purpose of rapid and convenient water drinking for a consumer can be realized.
