2. SRI to China Modification and Improvement Ideas and thought

4. 1 、 Use of organic fertilizer

5. Total/ha N: 225 kg P 2 O 5 : 90 kg K 2 O: 135 kg

6. 2 、 Plant super rice or super hybrid rice

7. Strong tillering ability Big root system

8. Row-direct sowing Thinning and adjustment

9. Controlled-water management Traditional(Deep water irrigation) NFRF(Dry-wet alternation)

11. 1 st time : steeping manures and fertilizer, field leveling and direct sowing Sowing rate: 13.5~15 kg/ha

12. 2 nd time : milk-fertilizer application and pesticides

13. 3 rd time : Tillering fertilizer application and pesticides

14. 4 th time : Panicle fertilizer （ P 、 K ） , pesticides

15. Dry-wet alternation

16. Important: Keep wet soil condition during filling stage for a good grain setting, usually keep a narrow water in the slot.
