[Spatiotemporal distribution patterns of winter wheat and spring maize root systems under intercropping].
In this paper, root samples of winter wheat and spring maize under intercropping were taken with large-bore soil auger, and the dynamics of their spatiotemporal distribution were studied. The results showed that both in vertical and in horizontal directions, the root mass of winter wheat decreased in power function, while that of spring maize decreased in exponent function. Multiple linear regression was made to establish the two-dimensional spatiotemporal distribution functions of intercropped winter wheat and spring maize root biomass, and the validation tests demonstrated that theses functions were available to describe the real growth status of test crops root systems.
