The mountains and hills in the south of China. There are many fruit trees planted in hilly areas. Taking Mayang as an example, millions of citrus trees with Mayang are used, most of the citrus trees with Mayang are used for spraying pesticide by using a knapsack sprayer at present, a small number of electric sprayers and motor sprayers are used, at least two people or even three people are needed for operating the electric sprayers or the motor sprayers at present, the motor sprayers do not need much time for spraying pesticide, but the preparation work is more, and water picking, pesticide dispensing, pipe placing and the like are needed. As most of farmers do not concentrate citrus trees, the spraying amount of the motor-driven spraying machine is large and is difficult to exert advantages. The transportation is very troublesome, and the pesticide is easy to waste. At present, the rice transplanting and the purchasing of the peasants are mechanized, but the field management is still relatively backward, farmers do not know when to apply fertilizer and spray pesticide, how much fertilizer is applied and how much pesticide is sprayed, the farmers are not clear at all, and more importantly, the existing sprayer is difficult to spray pesticide with large spraying amount and high efficiency.

The prior agricultural sprayers on the market are mainly classified into manual sprayers, electric sprayers and motor sprayers according to the power form. Though portable, manual and electric sprayer spray speed is slow, and is inefficient, and needs to change many times, makes a round trip to waste time and energy, and motor sprayer is efficient, but the machine constitution is complicated, and is heavy, carries inconveniently, and the cost is also higher, still needs to consume certain energy. More modern sprayer carrying modes include tractor-carried sprayers and remote control helicopter-carried sprayers. These sprayers all have fatal defect, are difficult to popularize in southern rural area in a large scale. For example: tractor-carried sprayers cannot be used for such paddy fields in south of China at all because the tractor is too heavy and falls down, and some farmlands have no way to go at all. The portable sprayer of the remote control helicopter has complex structure, high cost and easy damage due to improper operation.

Therefore, the sprayer with a brand new principle and a brand new structure is simpler and more reliable than the existing manual sprayer, more efficient and cheaper than a motor-driven sprayer, and can be used for applying foliar fertilizer or directly spraying and irrigating plants due to the large-area spraying and low cost.
