1results about How to "Reduce ineffective evaporation" patented technology

This specification provides one or more embodiments of a root-oriented water-saving irrigation device, including a base frame, a drip irrigation assembly, and a limiting support assembly. The base frame is a cylindrical structure used to insert into the soil and control the directional growth of crop roots. The drip irrigation assembly includes two sets of drip irrigation frames symmetrically arranged on the top periphery of the base frame. Each drip irrigation frame is internally threaded with an irrigation rod. Grooves are provided on both sides of the irrigation rod, and a sponge is fixed within each groove, with PAM (a water-retaining agent) placed inside the sponge. This device is suitable for all greenhouse applications and has a wide range of applications. Specifically designed for plastic greenhouse planting, it incorporates a precipitation impact correction formula, which can accurately adjust irrigation water demand based on factors such as the greenhouse's closure status, ventilation opening, and external precipitation. It possesses self-learning (automatic adjustment) optimization capabilities, continuously improving irrigation accuracy. The device can use a fixed cycle as an iteration unit, providing actual crop growth data based on measured soil moisture content data within the cycle.
