Abstract

This project aimed to investigate the relationship between light intensity and the growth rate of the green onion. As a typical kind of crop, green onions are frequently consumed and are known for their high nutritional value, which is a great sample of studying the universalization of crops. This project utilized a system of controlling variables, which changed the level of light intensity within three different kinds of blackout clothes (0% shading, 50% shading, 90% shading) with nine trails in three groups. This experiential research analyzed the impact of light intensity on the growth of green onions through the observation of their height difference in two weeks. The findings demonstrated that both lower and higher light intensity could increase the growth rate of green onions to some extent, which revealed superior resilience and provided an estimation of the light compensation and saturation points of green onions. Although the conditions of this research were limited, it still provided a direction in the area of increasing crop yields.
