  • Two fields of rice growth with normal methods and 3-S. The phenotypical differences are evident, much as seen with SRI.
  • 0429 Development of System of Rice Intensification for Rice Production in China

    1. 1. Development of SRI for Rice Production in China Slides from a powerpoint presentation made to a workshop on SRI, held at the World Rice Research Conference, Tsukuba, Japan, November 7, 2004 <ul><li>Dr. Zhu Defeng </li></ul><ul><li>China National Rice Research Institute </li></ul><ul><li>Hangzhou, PRC </li></ul>
    2. 2. Basic principles of SRI and functions Water saving, root growth, and fertilizer use efficiency Irrigation management Soil fertility Organic/chemical fertilizer Tiller growth, large panicle Sparse planting Tiller growth Younger seedlings Function Basic principle
    3. 3. Contributions of SRI Sustainable soil fertility Organic/chemical fertilizer Water saving Irrigation management Labor saving Sparse planting with younger seedlings Contribution Practice
    4. 4. Comparison of yield in SRI and check (Jiayou 99 variety), 2003 9.3 11.1 Yield (t/hm 2 ) 100.0 25.1 92.6 191 209.6 CK 119.4 25.3 91.2 222.8 215.7 SRI Relative yield(%) Grain weight (g /1000) Fertility (%) Grains (No./ panicle Panicle (No./m 2 ) TR
    5. 6. Analysis of factors of yield increase in SRI compared with check 100.0 1.73 Total 4.3 0.07 Grain weight 80.1 1.38 Grain no. 15.7 0.27 Panicle no. Contribution (%) Yield (t/hm 2 ) Item
    6. 7. Pattern of tiller growth in SRI and check
    7. 8. Light penetration
    8. 9. Experiment of water saving at CNRRI
    9. 10. Comparison of water consumption in SRI and check 39.5 3806.7 S2 44.7 3477.0 S3 22.4 4879.9 S1 0.0 6289.8 CK Rate of saved water (%) Water consumption (m3/ha) Treatment
    10. 11. Transplanting in shallow water layer
    11. 12. 33 DAS
    12. 15. Heavy panicles
    13. 16. Normal 3-S (SRI)
    14. 17. Sparse sowing Check
    15. 18. Wide row planting
    16. 19. Moist soil
    17. 21. Conclusions <ul><li>Rice management technology that matches new varieties/hybrids is needed to further increase yield </li></ul><ul><li>SRI principles match the current trends in the advance of rice cultivation technology </li></ul><ul><li>Site-specific SRI technology is needed to for raising the yields of Super-Rice and for greater water productivity </li></ul>
