Greenhouse hanging micro spray

Microirrigation can be divided into drip irrigation, micro sprinkler irrigation, and infiltration irrigation according to the different ways of water flow during irrigation. Drip irrigation is widely used among them.

Drip irrigation is a method of irrigation in which the emitter on the capillary at the tail of a micro irrigation system is a drip head or a drip irrigation belt that is integrated with the capillary to dissipate water under certain pressure and drip it into the roots of crops in a drip like manner. During use, the capillary and irrigator can be placed on the ground or buried 3040 centimeters underground. The former is called surface drip irrigation, while the latter is called underground drip irrigation. The flow rate of the drip head is generally 212 liters per hour, and the operating pressure is 50150 kilopascals.

Micro sprinkler irrigation refers to the use of a micro sprinkler head at the end of a micro irrigation system. The micro nozzle sprays water with a certain pressure (usually 200300 kPa) as a fine mist on the soil surface near the leaves or roots of crops. There are two types: fixed and rotating. The former has a small spraying range, while the latter has a large spraying range, large water droplets, and a large installation spacing. The flow rate is generally 10200 liters per hour.

Small tube outflow is a irrigation device that uses a microtubule with a diameter of 4 millimeters connected to a capillary to locally moisten the soil near crops in a fine flow (jet) shape. The flow rate is generally 80250 liters per hour. For tall fruit trees, a small drainage ditch is usually built around the trunk to disperse the water flow and evenly moisten the soil around the fruit tree.
