The results showed that the damage of rice stem borers was lower in the 1st crop season of the rotation system B , which was only 2%. The water demand amount was 37,668 m3/ha in the rotation system B (rice-soybean). Compared with the conventional rotation system A (rice-rice), the annual water demand was 44,370 m3/ha. The rotation system B(rice-soybean) was reduced 6,702 (m3/ha) than the conventional rotation system A (rice-rice), with a reduction ratio of 15.11%.In the comparison of rice yield at the 1st season, the rotation system B was increased 568 kg/ha, an increase of about 7%, and the net income was increased 15,023 nt/ha.The total income of the rotation system B was 239,595 nt/ha,which was more than the total income of the rotation system A which was 146,858 nt/ha, which can be increased 92,737 nt/ha and Increase ratio was to 63%.On the whole, the paddy rice field transferred to soybean rotation System can increase the production of rice in the 1st reason, while blocking or slowing the occurrence of pests and disease, and the efficiency of water was used best, which was one of the excellent rotation systems. |
