- 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
- 3. Normal 3-S
- 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. Seedling for transplanting -- and resulting plants
- 7. Vegetative Growth Vigorous tillering
- 9. 3-S roots on right
- 10. 3-S with Different Varieties 423
- 11. . 131
- 12. . 422
- 14. 水稻优质、高产、抗病新品种 “ 东农 03-33 ”
- 15. 3-S has good grain quality
- 16. Vigorous root development while in pots seen on right
- 17. Seedlings are started at the end of winter in plastic greenhouses
- 20. Seedlings Bundled for Transplanting
