Abstract:

This study aims to sort out the impact of foliar fertilization on crop productivity. Through extensive research on a large number of domestic and foreign literatures, it reviews the development of foliar fertilizers, summarizes the types and characteristics of different foliar fertilizers, and concludes the roles of different types of foliar fertilizers in promoting plant growth and alleviating plant stress. Moreover, it takes the stomata and cuticle on the leaf surface as the entry point to summarize the mechanism of action of foliar fertilizers. Research has found that when reactive oxygen species accumulate in large quantities within plants, it will reduce photosynthetic efficiency and affect crop growth. Foliar fertilization can enhance the antioxidant activity of crops, regulate photosynthetic activity, energy metabolism and nutrient assimilation and other physiological processes to promote crop growth. Finally, the problems existing in the practical application of foliar fertilizers and the prospects for further exploring the mechanism by which foliar fertilizers regulate plant growth and development are discussed and prospected.

Key words: foliar fertilizer, type and characteristics, growth promoting effect, relieve environmental stress, mechanism of action
