After the water pump entered the water inlet pipe, the water outlet gap between water spray lower clutch and the water spray upper clutch was spout from the water pump to along the downward high-speed flow of inlet tube outer wall, the rivers that flow downwards made field planting pipe upper end form the negative pressure, made the air of field planting pipe top pour into in the field planting pipe and along with rivers downward flow. The intraductal mobile air of field planting makes the root system of plant can carry out abundant respiration on the one hand to the ability of reinforcing root system absorption nutrient (the root system of plant absorbs transportation moisture and nourishment and all needs the energy of consuming, these energies are provided by root cell's respiration, the respiration is stronger, then the absorbing action of root system is stronger), when on the other hand air was from the intraductal flow of field planting, the particulate matter that carries in the air can be attached to the root system of plant, the root system of plant has played the purifying action to the intraductal air of field planting of flowing through promptly.

further, the spray head sprays water mist (nutrient solution is added into the water in the water tank) into the planting pipe to provide water and nutrients for the plant root system; meanwhile, the water mist can capture dust particles in air flowing through the planting pipe, and the water mist with the dust particles is finally attached to plant roots or falls into a water tank; meanwhile, the vaporization of water mist can be accelerated by the flowing air in the field planting pipe, the vaporization of the water mist can reduce the temperature in the field planting pipe in summer, and the influence of overhigh temperature of a plant root system on normal growth is avoided.

every interval a period (1 to 24 hours), the controller increase the output of water pump for the inlet tube increases together with the water pressure in the water spray top connection, the spring atress of piston body upper end increases the compression and makes piston body rebound, thereby make the water jet switch on, the water jet sprays rivers to the field planting inside pipe wall, rivers flow along the field planting inside pipe wall, rivers flow downwards in-process have partly can receive blockking of field planting elbow, and trickle downwards along the root system of plant, wash away to the plant root system, the dust granule attached to on the root system can fall into the basin along with rivers.

according to the invention, water in the butt joint water tank is filtered by the filtering component and then discharged into the water purifying tank body, so that on one hand, the water spraying head and the atomizing head are prevented from being blocked by impurities in the water, on the other hand, the impurities in the water tank are stored in the wastewater box after being filtered, only regular cleaning is needed, the water in the water tank can be continuously used for a long time, and frequent water replacement is not needed.

at the ascending or initial stage that descends of electric cylinder drive cartridge filter, the linkage slider can upwards or one section distance of downstream along vertical spout, the linkage slider is last, the lower slip in-process drives the carriage and rotates, drive magnet on the carriage and steel material's driven gyro wheel between drive wheel drive brush yoke through magnetic force, thereby make the brush hair on the brush yoke under to the filter terminal surface scrub, make the filth and the filter of terminal surface break away from under the attached to the filter, it is less to make the filter downstream move and carry out filterable in-process resistance.
