Applying nitrogen fertilizer in stages is an effective way to enable unlimited-growth tomatoes to better absorb nutrients and increase yields. This study introduces the research situation in recent years on the impact of when and how many times nitrogen fertilizer is applied on the fruit setting quantity and total yield of tomatoes. It compares the effects of one-time fertilization only at the time of planting and staged fertilization, elaborates on how staged nitrogen application helps unlimited-growth tomatoes use nitrogen fertilizer more efficiently, how to extend the fruiting time, and how to make the fruits more easily obtain nutrients. The relationship between this fertilization method and the climate, the growth rhythm of tomatoes, as well as the coordinated growth between roots and branches and leaves was also discussed. This study aims to provide a scientific basis for improving fertilization methods, increasing yields, and making planting more environmentally friendly and sustainable.
