Abstract: This paper aims to explore the possible consequences of the nitrogen deposition and growth of macadamia seedlings in the atmosphere. By setting up a control group and a test group, a total of 20 young macadamia nuts were planted and cultivated in the normal environment of the planting base of the agricultural institution. The growth environment of the experimental group simulates atmospheric nitrogen deposition. In order to make the experiment fair, the two groups of plants have the same supply, soil conditions and other growth conditions, and the two groups of plants were cultivated and observed for a period of three years. The results showed that atmospheric nitrogen deposition has a great influence on the growth and fruiting of young macadamia nuts. The number of 20 plants in the experimental group was far less than that in the control group, and the survival rate was 15% lower than that in the control group.

Keywords: atmospheric nitrogen deposition; nitrogen deposition; macadamia seedlings; plant cultivation and growth; plant fruiting; experimental comparison and analysis.
