Abstract: Through analyzing 22,20,18,8,5 perennial hops respectively in the test, salty ions in the farmland soil different aged hops were determined, at the same time, changing property of salty ions in soil for different aged hops and their relation with quality in hops were analyzed. The results showed：Soluble salinity content in soil sharply increased with the hops age rising, while the increased extent decreased with the soil layer deepening into (in general, the change trend was still rising). The change order of all ions was CL-＞Ca2+＞Mg2+＞Na+＞K+＞SO42-. By vertical-section analysis，as far as the salty ions content in soil were concerned, 0-20cm layer＞20-40cm layer＞40-60cm layer. Soil layer in the 0-20cm，soluble salinity in soil was 0.401%，0.298%，0.256%，0.321%，0.185% respectively at the 22-year，20-year，18-year，8-year and 5-year. The soluble salinity at the first four age were 2.17，1.61，1.38 and 1.72 times respectively as that at the 5-year，and the difference was remarkable. The superficial accumulation of the salty ions was an important cause to decrease the α-acid in hops.
