The Effect of Water and Nitrogen Regulation on Potato Growth in Arid Regions

With the development of heavy industry around the world, the utilization of water and land resources is gradually increasing, and the problem of water demand and supply has become increasingly serious, therefore, the application of irrigation methods for water-saving and water-storage is inevitable. Due to the severe drought in Northwest China, the annual precipitation is less than 200mm, resulting in frequent sandstorms and serious soil desertification. To protect the environment in arid areas, it is imperative to adopt efficient water and nitrogen control technology. Deficit irrigation and nitrogen fertilizer management is a technology that involves the water and nitrogen requirements during potato growth, regulation methods, and the influence of environmental factors on the regulation effect. In terms of water and nitrogen requirements, potatoes have different needs for water and nitrogen at various growth stages. In the early stages of growth, potatoes have relatively low water requirements, but as the plant grows and tubers form and expand, the need for water gradually increases. During the growth process of plants, nitrogen is an essential basic element, and the supply of appropriate amounts of nitrogen fertilizer plays an important role in increasing the yield and improving the quality of potatoes. Water and nitrogen regulation is mainly achieved through irrigation and fertilization techniques. In terms of fertilization, nitrogen fertilizer is applied in a timely and appropriate manner according to the growth stage and needs of potatoes, while also being combined with other nutrients such as phosphorus and potassium to meet the growth needs of potatoes. In terms of environmental factors, the effect of water and nitrogen regulation on potatoes is also influenced by environmental conditions. Suitable temperature and light conditions are conducive to potato growth and tuber formation and expansion, while soil type affects the retention and supply capacity of water and nutrients. So, the proper use of this technology can bring about the peak of potato production.
