0605 Non-flooding Rice Farming Technology In Irrigated Paddy Field

  1. 1. Non-flooding Rice Farming Technology In Irrigated Paddy Field China National Rice Research Institute Dr. Tao Longxing
  2. 2. SRI to China Modification and Improvement Ideas and thought
  3. 3. Non-flooding Rice Farming In Irrigation Paddy Field <ul><li>Main technical components of NFRF </li></ul><ul><li>Use of organic fertilizer </li></ul><ul><li>Super rice or super hybrid rice & direct sowing </li></ul><ul><li>Controlled water management/Physiological requirement by plant </li></ul><ul><li>Weeds control by “Gucaobai”,senescence control by “Lilibao” </li></ul>
  4. 4. 1 、 Use of organic fertilizer
  5. 5. Total/ha N: 225 kg P 2 O 5 : 90 kg K 2 O: 135 kg
  6. 6. 2 、 Plant super rice or super hybrid rice
  7. 7. Strong tillering ability Big root system
  8. 8. Row-direct sowing Thinning and adjustment
  9. 9. Controlled-water management Traditional(Deep water irrigation) NFRF(Dry-wet alternation)
  10. 10. <ul><li>1 st time Watering: steeping the manures and fertilizers, field leveling ,seedbed making , direct sowing; </li></ul><ul><li>2 nd time watering at 3~4 leaf stage: milk-fertilizer application and pesticides; </li></ul><ul><li>3 rd time watering at 7~8 leaf stage: Tillering fertilizer application and pesticides; </li></ul><ul><li>4 th time watering at 12~13 leaf stage: Panicle fertilizer, pesticides and fungicides. </li></ul>Water and fertilizer management Four times full irrigation only
  11. 11. 1 st time : steeping manures and fertilizer, field leveling and direct sowing Sowing rate: 13.5~15 kg/ha
  12. 12. 2 nd time : milk-fertilizer application and pesticides
  13. 13. 3 rd time : Tillering fertilizer application and pesticides
  14. 14. 4 th time : Panicle fertilizer ( P 、 K ) , pesticides
  15. 15. Dry-wet alternation
  16. 16. Important: Keep wet soil condition during filling stage for a good grain setting, usually keep a narrow water in the slot.
  17. 17. Dew in early morning Judgment of water stress
  18. 18. Weeds control by “Gucaobai” 谷草败 CK Gucaobai
  19. 19. Lilibao CK Senescence control by “Lilibao” during later maturation
  20. 20. Non-flooding Rice Farming In Irrigated Paddy Field
  21. 21. NFRF TRF IT : Productive tiller stage , PT:max tiller stage , YD : young panicle init. , H : Heading , YR : Yellow rip.
  22. 22. NFRF TRF Development stage
  23. 23. NFRF TRF
  24. 25. NFRF TFR
  25. 26. 47.9% 34.7%
