In the growing season of Gannan navel orange, the rainfall is more and uniform, the irrigation cost can be reduced, and irrigation needs to be carried out in the case of less rainfall or drought season. In spring in particular, a humid soil environment is needed to facilitate the blossoming and fruiting of the navel oranges; the summer is the key period of the growth of the navel orange fruits, water needs to be watered once when the navel orange fruits do not fall in every week on average, and if the navel oranges meet dry seasons, the watering frequency is higher, and the water amount is larger.
In the navel orange plantation orchard in the Jiangxian mountain area, wires are inconvenient to erect and high in cost when the orchard is not near a village, particularly in an area 6 kilometers away from the village. Traditional water lifting equipment such as water channels, waterwheel, manpower waterwheel and the like lose efficacy in hilly and mountainous areas, local common people mainly irrigate fruit trees by picking water from small rivers, and the local common people are hard to eat and time and energy consuming, very inconvenient and troubled by about 70 thousands of fruit growers in Jiangxnan.
At present, a novel water taking machine without energy consumption (with the notice number of CN 202850100U) is designed in northern water shortage areas, the working principle of the novel water taking machine is that a mixture of silica gel and sand grains in an adsorption pipe is used as an adsorbent, water vapor is adsorbed at night, the water vapor is separated out after the temperature rises in the daytime, and the water vapor is liquefied and collected to achieve the purpose of taking water in arid areas. However, the method has small water intake and high cost, is mainly used for extracting drinking water in perennial arid areas in the north and is not suitable for agricultural irrigation. The manpower waterwheel is restricted by the distance of water delivery and is not suitable for irrigating in mountain areas.
