After considering hay yield and isoflvone content,the best fertilizing rate(50 kg N/hm2,120kg P_2O_5/hm~2) which could get higher isoflavone yield was obtained.

The results showed that: ① the flavonoid content and yield of root-induced callus was higher than hypocotyl and cotyledon-induced callus;② the flavonoid yield of root-induced callus was stable during 3～12 subculture generati.

The isoflavone content change during the process of soybean sprouting was researched,and the approach of using accelerant to increase the isoflavone content of soybean sprouts was explored.

In this paper,effects of nitrogen and phosphate fertilizer on hay yield,isoflavone content and yield of red clover were studied.

The method for the determination of isoflavone content was developed,and the membrane separation conditions of isoflavones including membrane material type and membrane hole number,membrane regeneration,and the relationship of membrane flux with operation pressure and temperature were investigated.
