The invention discloses a water-saving landscaping irrigation device and an irrigation method, and relates to the technical field of garden machine.The water-saving landscaping irrigation device comprises a base, a water tank is fixedly installed on the top of the base, a water adding opening is connected to the upper portion of one side of the water tank in a penetrating mode, a water pump is fixedly installed on the upper portion of one side of the water tank, and meanwhile the water pumping end of the water pump is connected with the water tank in a penetrating mode; a hollow pipe is fixedly installed at the top of the water tank, the water supply end of the water pump is connected with the hollow pipe in a penetrating mode, the irrigation assembly is arranged at the top of the water tank, the hollow disc is arranged above the water tank, the bottom of the hollow disc is connected with a connecting pipe in a penetrating mode, and the connecting pipe is rotationally connected with the hollow pipe. Two groups of water outlet pipes symmetrically penetrate through the top of the hollow disc; the irrigation range can be widened while landscaping irrigation is conducted, the area near the water tank can be irrigated, irrigation uniformity can be guaranteed, the irrigation effect is improved, repeated irrigation is avoided, and the water saving effect is achieved.

This utility model discloses a drip irrigation device for agricultural irrigation, relating to the field of drip irrigation technology. It includes a water delivery pipe and an irrigation mechanism. Several connecting blocks are fixedly connected to the outer wall of the water delivery pipe. During the movement of the connecting plate, the device causes inclined plate one to contact inclined plate two. After contact and continued movement, inclined plate two forces a sliding rod to slide outwards on the support plate. At this time, spring one is subjected to the squeezing force of inclined plate two. When inclined plate one moves beyond inclined plate two, inclined plate two is no longer pushed by inclined plate one, the squeezing force on spring one disappears, and inclined plate two returns to the top of inclined plate one, limiting and locking inclined plate one. When the drip head becomes clogged, simply pull the pull ring to remove inclined plate two from limiting inclined plate one, and then pull the drip pipe out of the inlet groove, quickly completing the replacement and cleaning of the drip head, significantly improving the convenience of agricultural irrigation.

This invention discloses the application of a heteropoly compound / PVA composite in water retention of sandy soil. The invention prepares the heteropoly compound / PVA composite by mixing polymer polyvinyl alcohol with a Standberg-type heteropoly compound or its derivatives, which is then used for water retention in sandy soil. The heteropoly compound / PVA composite of this invention can significantly improve the water and fertilizer retention capacity of sandy soil, and has high adhesion ability. It can withstand strong winds in arid regions, is not easily blown away and loses its effectiveness, and will not disperse into the air causing particulate pollution. After gradually losing water, the sand amendment forms a porous membrane on the surface of the gravel, maintaining the soil's aeration and permeability, and plays a positive role in the restoration of degraded soils in desert areas.

The utility model discloses a garden maintenance device, and relates to the technical field of garden maintenance, the garden maintenance device comprises a walking path, the top surface of the walking path is provided with a long groove, a plurality of impounding reservoirs are arranged right below the walking path, the inner wall of the lower part of the long groove is integrally connected with a plurality of supporting columns, and the supporting columns are connected with the long groove. A plurality of floors are placed on the supporting columns; according to the garden maintenance device, the spraying equipment is combined with a path in a garden, in rainy days, rainwater can flow down from a gap between the two fillets, is filtered by the filter plate and is stored in the water storage pool, the effect of saving water resources can be achieved, follow-up irrigation is facilitated, and the garden maintenance device is convenient to use. The upper hole diameter of the spraying hole in the nozzle is larger than the lower hole diameter, the two sides of the nozzle body are inclined faces, and the face, away from the walking path, of the nozzle body is an arc face, so that the spraying range can be enlarged, grassland on the edge of the path can be fully irrigated, sprayed water cannot splash to people walking on the path, and the using effect is good.

The present invention relates to the field of plant cultivation, and discloses a modular cross-liquid flow plant hydroponic unit, a hydroponic device and a hydroponic system. The modular cross-liquid flow plant hydroponic unit comprises a mounting frame, two planting plates and a plurality of guide plates. The two planting plates are fixed on opposite sides of the mounting frame. The mounting frame and the planting plates enclose a flow cavity.
