0404 The 3-S System of Rice Cultivation

  1. 1. The 3-S System of Rice Cultivation Prof. Jin Xueyong Northeastern Agricultural University Haerbin, Heilongjiong Province, China 10th National Workshop on High Yielding Rice, Haerbin
  2. 2. The ‘3-Super’ System of Improved Cold-Zone Rice Production <ul><li>Use the most productive variety for conditions; usually super hybrid rice variety will be best </li></ul><ul><li>Super-wide spacing between plants – single seedings @ 10,000 plants/mou ( ~ 25x25 cm) </li></ul><ul><li>Farmers will get super yields if using also other favorable growing conditions , such as water management and increased soil organic matter </li></ul>
  3. 3. Normal 3-S
  4. 4. 水稻三超栽培技术原理 <ul><li>延扩水稻营养时空,释放水稻个体生产力,强化双冠性能,促进水稻 “ 源足、库大、流畅 ” 而大幅度增产。 </li></ul>Field Inspection
  5. 5. With 3-S, 45-day-old seedlings are transplanted (older seedlings are needed with colder climate) with wide spacing and no flooding of the fields, reducing water by 50% and seed rate by 80-90%
  6. 6. Seedling for transplanting -- and resulting plants
  7. 7. Vegetative Growth Vigorous tillering
  8. 8. Vigorous roots
  9. 9. 3-S roots on right
  10. 10. 3-S with Different Varieties 423

  12. 12. . 422
  13. 14. 水稻优质、高产、抗病新品种 “ 东农 03-33 ”
  14. 15. 3-S has good grain quality
  15. 16. Vigorous root development while in pots seen on right
  16. 17. Seedlings are started at the end of winter in plastic greenhouses
  17. 18. Seedling Production
  18. 19. Growth in Greenhouses
  19. 20. Seedlings Bundled for Transplanting
  20. 22. Wide Spacing of Plants <ul><li>Average spacing 15 cm (13-17 cm) by 40 cm (37-43 cm), 1-2 per hill </li></ul>
