Atomizing irrigation belongs to one of micro irrigation, and is characterized in that pressurized water at the head part is conveyed to a field through a pressurized pipe network, and then is sprayed into mist through a special atomizing nozzle for irrigation. The diameter of the atomized irrigation raindrops is smaller than 0.5mm, so that crops are covered by cloud and fog, especially when drought, high temperature and low humidity occur, the humidity among the plants of the crops can be increased by more than 20%, the temperature is reduced by 3-5 ℃, the relative water content of the leaves is increased by 10-15%, and therefore the afternoon nap phenomenon of inhibiting photosynthesis of the crops due to high temperature and low humidity is slowed down or eliminated, and the normal growth of the crops is promoted. The atomizing irrigation technology is used for irrigating crops, has the characteristics of high atomizing degree of irrigation water, capability of increasing the humidity among plants, improving the microclimate in the field and the like, and meanwhile, atomized raindrops are directly supplied to the blades and slowly reach the ground, so that the soil moisture is increased, the soil structure is not damaged, the effect of cooling and humidifying is achieved, and the water saving effect is quite obvious.
The existing atomizing irrigation is generally used for greenhouse irrigation, and for open outdoor large-scale irrigation, a self-propelled irrigation vehicle is generally adopted, and the size of irrigation raindrops sprayed is changed by changing a spray head on the irrigation vehicle, so that atomizing irrigation is realized. However, the irrigation amount of the self-propelled irrigation vehicle cannot be precisely controlled, and manual control is required during irrigation. In addition, a water and fertilizer integrated watering device is arranged between plants by adopting pipelines, atomization watering is realized by utilizing an atomization nozzle, meanwhile, a fertilizer pipe is connected by the pipelines, water in the watering pipeline is used as a carrier, fertilizer is sprayed to the field, and the fertilizer absorption effect is improved. However, when the fertilizer is dissolved, the fertilizer is partially dissolved slowly, the atomizing nozzle is blocked to influence the irrigation effect and the irrigation rate, and meanwhile, the fertilizer solution concentration is uneven due to different fertilizer dissolution rates, so that the fertilization effect is influenced.
In view of this, we propose an intelligent farmland atomizing irrigation device and a method of use thereof.
