Abstract: In order to explore effect of different subsoiling machines on growth and yield of wheat and further confirm effect of subsoiling on growth of wheat, different types of subsoiling machines were tested in Gaocheng District of Shijiazhuang City．Results showed that there was no significant difference in plant height between four treatments and control group, which was 66～68 cm．Number of ears treated by wing shovel subsoiler was the highest, 6.3% higher than that of control group．Number of grains per ear in wing shovel subsoiler treatment was the highest, 1.9% higher than that of control group．Quality of 1000 seeds treated by vibratory subsoiling machine was the highest, which was 11.3% higher than that of control group．Theoretical output of vibratory subsoiler treatment was the highest, 10.5% higher than that of control group．Results showed that subsoiling could significantly promote growth and yield of wheat．
