2results about How to "Fully irrigated" patented technology

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.
