  1. The results show that the physical and chemical conditions of the corn belt phaeozem have significant different in different profile morphological characteristics. in another way, soil composition of three phases, content of available water, nutrient content and composition of humus have significant different in different profile morphological characteristics. among three groups of profile morphological characteristics, corn yields of phaeozem in " flat type " boundary soil ( depth = 30cm ) were the most, reached 8. 22t / hm2on average. corn yields of phaeozem in " wave type " boundary soil ( depth = 15cm ) reached 7. 55t / hm2 on average

    這兩種界面構造對玉米產量影響差異顯著， 「平面型」界面土壤抗逆性較強，產量最高，平均產量達8 . 23t / hm ~ 2 ，而「波浪型」界面土壤抗逆性較差，它可以分為兩種情況：當耕層厚度15cm時，產量處于中等水平，平均產量為7 . 55t / hm ~ 2 ；當耕層厚度15cm時，產量最低，平均產量為6 . 65t / hm ~ 2 ，此種土壤處于丘陵漫崗區，產量受水土流失影響較大。
  2.
