This paper reports on the research of the application of iron on the serious chlorotic peach in 1992-1993.The results showed that the leaf can be tnrned green in 7-10 days and the rotio of return normal plants approximated to 100% by root irfusion method with TL-Fe .After TL-Fe application ,the content of total iron in the leaf has increased by 71%,the content of chlorophy 11 336.7%,the activity of perhydrogenase 503.4%,the number of fruit set pet plant 424.5 %,the single-fruit weigh 71%and improved the fruit quality.
