Abstract:

Recently, the areas with high concentration of ozone are ever\|increasing, and the studies on ozone effects on plants are growing in depth. Studies are developed from the most basic ozone damage phenomenon to ozone damage mechanism, and to ozone damage effect on plant in vivo elements. Thus, these studies have provided the basis for developing scientific agricultural management measures and ensuring high and stable crop yield. This paper summarized the research progress on the effect of ozone concentration rising on crop in vivo nutrient elements at home and abroad, and also on plant ozone protection. It has provided theoretical reliance to scientific fertilizing, rational cultivation, and to ensure grain safety. The paper also pointed out several aspects for further study in ozone pollution research field in China, so as to promote studies on plant nutrition under atmospheric environment change condition.

Key words: ozone, C/N, nutritional elements, protection
