Abstract: Distributions of roots and rhizosphere nutrients were evaluated for wheat and maize intercropping system.The effects of intercropping on exudate of organic acid in the roots were discussed.Pot experiments and solution cultivation experiments were carried out.The results showed that intercropping increased growth of roots and their exudate of organic acid.It also made N content increase and P,K contents decrease in the rhizosphere soil of maize.On the contrary,the N content decreased and P,K contents increased in the rhizosphere soil of wheat.The effects of intercropping on the roots of wheat and maize were found quite distinct.
