Experiments on Characteristics of Wheat Roots Difference between Apple-wheat Intercropping System and Wheat Monoculture System

The difference characteristics of wheat roots between the apple wheat intercropping and the wheat monoculture(CK) was conducted in the hilly region of Taihang Mountains. The results show that: during the wheat double ridge maturity stage, the amount of wheat fine roots in the intercropping is about 4.74% more than that in the CK; there is no significant difference of vertical and temporal roots distribution trend between the intercropping and the CK.
