Abstract:

In order to promote the application of PAM in tomato production，field experiments of PAM with different application methods on soil moisture and tomato growth were conducted in Hetao irrigation district，Inner Mongolia.The results indicated that PAM enhanced soil moisture，especially in young fruit stage,and the effects of broadcasting was stronger，furrowing and mixing were weaker.Among the different application methods,only broadcasting improved the photosynthetic rate and transpiration rate,boosted the growth of roots，stalks and leaves，and remarkably enhanced the yield and soil water use efficiency,while furrowing and mixing lowering the yield and soil water use efficiency significantly.In the tomato production broadcasting PAM should be the optimum method.
