Sprinkler irrigation equipment has been widely recognized in greenhouse greenhouses, field planting, flower planting, landscaping and other planting environments because of its wide application environment and semi-automatic or even fully automated operation management. Irrigation using sprinkler irrigation equipment can effectively increase the utilization of irrigation water and increase crop yield to a certain extent. In fact, sprinkler irrigation as an irrigation method also has its limitations and its shortcomings. Then, what are the shortcomings of sprinkler irrigation equipment?
1. The sprinkler irrigation quality of sprinkler irrigation equipment is susceptible to natural wind.
When the sprinkler irrigation equipment is working, the irrigation water can be crushed and sprayed through the nozzle. No matter how much the sprinkler irrigation equipment has a long range, a certain amount of water will be atomized and vaporized and become very light. If there is wind blowing at this time, It directly destroys the natural scattered orbit of water, and can also greatly accelerate the natural evaporation of water. As a result, it will seriously affect the uniformity of sprinkler irrigation and destroy the design sprinkler irrigation capacity of sprinkler irrigation equipment. If sprinkler irrigation continues in a windy environment, water will be present in some areas of the soil, and some areas will be dry and waterless, eventually reducing crop yield.
Therefore, in the actual sprinkler irrigation process, if the wind is greater than 3, it is recommended to stop sprinkling and continue when there is no wind. If the area is windy all the year round and the sprinkler irrigation equipment is selected for irrigation, then the adverse effects of the wind should be fully considered in the stage of designing the sprinkler irrigation equipment, and the irrigation effect should be corrected by altering, misaligning and predicting the deviation in advance. If the wind is unstable, consider switching to other irrigation methods.
2. The sprinkler quality of sprinkler irrigation equipment is susceptible to humidity.
If the air humidity in the irrigated area is too low, the natural evaporation loss of the sprinkling water will increase, and the utilization coefficient of the irrigation water will be correspondingly reduced. This is not in line with the concept of water-saving irrigation. Therefore, if the air humidity during the day is too low, then it is selected. Sprinkle irrigation at night to ensure the best sprinkler effect.
3. The energy consumption of the sprinkler irrigation equipment is high.
As a kind of water-saving irrigation equipment, sprinkler irrigation equipment is different from the “soft and soft” of drip irrigation equipment. The main pipe of sprinkler irrigation equipment usually bears higher pressure. After all, sprinkler irrigation equipment needs to spray water and require a certain range. Therefore, it is more common to add electric drive booster equipment to the sprinkler irrigation system. This energy consumption is much higher than that of the drip irrigation system, and there is a conflict with the concept of green water-saving and water-saving irrigation. Therefore, at home and abroad, Low-range sprinkler irrigation and micro-sprinkler irrigation are the main types of promotion.
