Master the method of topdressing edible fungus, micro-spray and artificial fog system are commonly used in flower irrigation.

Micro-sprinkler is one of the common ways of water-saving irrigation. The micro-sprinkler irrigates crops in the state of spraying water flow. In the micro-spray system, all kinds of micro-sprinklers and sprinkler belts are commonly used emitters. The micro-sprinkler system used for flower cultivation in the open field usually lays sprinkler belts on the surface or inserts the micro-sprinkler; in facility horticulture, the micro-sprinkler is usually hung upside down from the skeleton of the facility to avoid affecting the micro-spray system to irrigate other crops.

Rotary micro-sprinkler and scattered micro-sprinkler are the two most common sprinklers in micro-sprinkler system. In general, the function of rotary micro-sprinkler is to supplement irrigation, while scattering micro-sprinkler is divided into refractive micro-sprinkler and centrifugal micro-sprinkler, which has two functions of irrigation and humidification and cooling. Centrifugal micro-sprinkler is often used for atomization irrigation in soilless cultivation and has the effect of humidification and cooling.

In order to create field microclimate, drip irrigation and micro-spray should be combined, mainly drip irrigation, and micro-spray system is mainly used for supplementary irrigation and humidification and cooling.

When using the micro-spray system, you should pay attention to the following:

1. When the micro-sprinkler is installed upside down, an anti-drip device must be installed to prevent the micro-sprinkler from causing harm to flowers after the water is stopped.

two。 In the facility, the micro-sprinkler system and the drip irrigation system share the same water source at the same time. It is necessary to install a pressure reducing device in the drip irrigation system or a local pressure device in the micro-sprinkler system to prevent the drip irrigation system from blasting or the micro-sprinkler system from not spraying.

3. The micro-spray device must be cleaned regularly, it is recommended to clean after each irrigation, and it is taboo to remove the filter element.
