Root Growth and Distribution of Winter Wheat With Sprinkler and Surface Irrigation

Based on the characters of soil moisture distribution of both sprinkler and surface irrigation, the root growth and distribution of winter wheat were discussed. Then root growth and distribution models of winter wheat were presented for sprinkler and surface irrigation with different water quotas. At last the differences and the similarities of root density relative distribution on profile between sprinkler and surface irrigation were analyzed in detail. The results are useful for nicely establishing root intake water model and modeling soil water movement.
