Sugarcane, originating in China, is a tropical and subtropical Cash crop. Guangxi is located in the southern and middle subtropical monsoon climate zone, with hot and rainy seasons. It is the largest suitable area for sugarcane production in China, with an annual planting area of 680-7.8 million mu, accounting for 40% of the total sugar production in China. After years of development, the sugar industry has become a pillar industry of Guangxi's economy.

However, over 90% of the raw sugarcane in Guangxi is planted on dry land without irrigation conditions and with a relatively shallow cultivation layer. The yield and sugar content of raw sugarcane are not only affected by variety, fertilization level, and cultivation technology, but also to a large extent by meteorological conditions, especially disastrous weather such as spring drought and autumn drought in Guangxi, which have a greater impact on the yield and sugar content of raw sugarcane. Severe drought in winter and spring affects the timely sowing and emergence of sugarcane in winter and spring, reducing the number of effective stems and inhibiting seedling growth; Autumn drought affects the growth of sugarcane, and the occurrence of severe autumn drought will lead to a decrease in sugarcane yield and quality, low sugar content, and also affect the planting and seedling growth of autumn planted sugarcane. Irrigation and soil improvement are active methods for drought prevention. Therefore, we should adapt to local conditions, vigorously develop water-saving irrigation, and establish the concept of long-term drought resistance. The main measure should be to take the path of agricultural water-saving irrigation. The effective way to maximize the benefits of water-saving irrigation in drought resistance work is to promote high-tech water-saving irrigation.

Practice has proven that sprinkler irrigation equipment, especially reel type mobile sprinkler irrigation equipment, can achieve twice the result with half the effort in drought resistance due to its lightweight design structure, flexible movement, convenient use, and strong applicability to soil and water. If used and managed properly, it can achieve twice the result with half the effort.

The reel type sprinkler irrigation machine is suitable for plots ranging in size from tens of acres to hundreds of acres due to its wide variety of models. When it works, it usually needs to supply water from the underground main pipeline or main channel led out of the machine well, using high-pressure spray guns to generate long-distance range, and using the rotation of the reel to drag out the pipes and spray guns, until the irrigation of the land is completed. The entire process is fully automated, and the control of irrigation volume is achieved by controlling the speed of the reel rotation. The power for the reel rotation is only provided by the water source power - the pump, without the need for other energy sources such as electricity or diesel. After completing the irrigation of one plot, it can be towed to another plot for irrigation, which is very flexible and flexible. The adaptability of reel type sprinkler irrigation machines to different terrains is unmatched by other irrigation equipment. Even on uneven land, it can work normally and operate very simply. Generally, one to two laborers can control 5-8 such devices.

Good sprinkler irrigation machines, such as the "Rain Star" sprinkler irrigation machine manufactured by Huatai Baoer Irrigation Equipment Engineering Co., Ltd., have a lifespan of over 10 years and significant economic benefits. Guangxi's Nanning, Beihai, Liuzhou and other regions have achieved significant social, economic, and environmental benefits by promoting the use of this equipment on a large scale and actively developing water-saving agriculture.

In short, drought relief and disaster reduction is a systematic project, and relevant departments should focus on improvement and fully cooperate to achieve comprehensive and unified management of water resources. In particular, efforts should be made to research and promote the application of high-tech in drought relief work, in order to achieve optimal allocation and scientific management of water resources within the maximum range, minimize drought losses, and achieve maximum economic, social, and ecological benefits.
