This paper presents the main results of research on storage of melon and fruit in Xinjiang from 1976 to 1981.,In this period of time, we had inrestigated the storage of Seedless grapes, Hamimelons and kuerle-pears in Xinyiang with X-ray, β-ray and atmospheric negative ion which were produced by a 2 MeV electronic electrostatic acceleratoro These experimental results are shown as follows. The seedless-grapes were treated by the atomespheric negative ion have better storage effects. than those treated by both the X-ray or the β-ray,The Hami-melons were radiated with the low dose of β-ray evidently have longer storage period and bigger.,The Kuerle-Pears were treated by the atmospheric negative ion. nine months later, 91.9% of the Kuerle-Pears were survived and no big change of skin, flavor, quality and form of the Kuerle-Pears were seen.
