Micro sprinkler
Micro-sprinkler irrigation is a form of irrigation that uses refraction, rotation, or radiation micro-sprinklers to evenly spray water to areas such as crop branches and leaves, and belongs to the category of micro-irrigation. The working pressure of micro-sprinkler irrigation is low and the flow rate is small. It can not only increase the soil moisture regularly and quantitatively, but also improve the air humidity and adjust the local microclimate. humidification and cooling.
drip irrigation
Drip irrigation is a form of irrigation in which water is dripped into the soil near the roots of plants evenly and slowly. Evaporation, under drip irrigation conditions, except the soil moisture immediately below the dripper is in a saturated state, the soil moisture in other parts is in an unsaturated state, and the soil moisture infiltration and diffusion mainly rely on capillary tension.
However, if the drip irrigation time is too long, infiltration may occur under the root system, so drip irrigation is generally completed by high-tech computer manipulation, and some are manually operated. Drip irrigation has low water pressure and saves water. It can be used to irrigate each plant separately in areas where different plants grow. However, pressure compensation is required for sloping land. It can be controlled by a computer by adjusting the valves in different sections. The key is to control and adjust the pressure and Remove particulate matter from water to prevent clogging drip holes.
Plastic pipes are generally used for water transportation, which should be black, or covered under the mulch to prevent the growth of algae and prevent the pipes from aging due to ultraviolet radiation. Drip irrigation can also be done with porous ceramic tubes buried in the ground, but it is more expensive and is only sometimes used for turf and golf courses.
