Abstract

Corn is the third largest food crop in China after rice and wheat. It is mainly used in animal husbandry and processing industries. It is of great significance for enriching citizens' food bags and the combined use of "grain, economy, and feeding". Especially in the semi-humid and semi-arid regions of northwest China such as Ningxia, Shaanxi, Gansu, and Inner Mongolia, corn is an important food crop, but facing unfavorable environments such as drought and low rainfall, the yield is not high. The growth of corn is also inseparable with the application of fertilizers such as nitrogen, phosphorus, and potassium. Therefore, this article studies different combinations of nitrogen, phosphorus, potassium, and other fertilizers in order to achieve the purpose of increasing yield and efficiency of corn under adverse conditions such as dry farming. The contradiction between the supply and demand of fertilizer.
