The basic characteristics of the whole process were gained. When the seedling falling out of the tube feet, the difference of the time interval between 2 neighboring seedlings wasn't notable, and the difference of the time interval of 2 neighboring seedlings wasn't notable and the agricultural time was not special notable. These results showed that the uniformity of the pneumatic ordered throwing transplantation was excellent and could meet the demands from design and agriculture; Upstanding state was primary as the seedling falling out of the tube feet, it showed that the seedling could keep erective preferably when the seedling falling to the field.

Results The recovery time of bowel sound was 8-112 h (M=28 h) in the treated group and 16-24 h (M=46 h) in the control group, with a significant difference P=(0.0001. The time of anal exsufflation in the treated group was 2-116 h (M=56 h), and 24-147 h (M=82 h) in the control group, with a significant difference (P=0.0001). The electroenterogram revealed that control activity, continuous response activity and contractive electrical complex were significantly stronger in the treated group than in the control group.
