Workshop on the System of Rice Intensification, Exchanging Experience in
China, the Democratic People's Republic of Korea and Internationally, organized and
hosted by the China National Rice Research Institute (CNRRI), with support from The
Asia Foundation.
Hangzhou, China, February 28-March 2, 2010
1. Workshop on SRI rice technology Evaluation of Key Factors of SRI Method Dr. Lin Xianqing E-mail: xqlin2003@163.com China National Rice Research Institute
2. Reporting Content: Ⅰ. Seedlings Ⅱ. Spacing Ⅲ. Organic fertilizer Ⅳ. Water management Ⅴ. Comparison between SRI and traditional method Ⅵ. Operation of SRI
18. Changes in redox potential of SWD at different growth stages ( A----SWD)
19. The number of actinomycetes under different fertilizer and water management regimes I1 =SWD; I2 = CKF1 = Chemical fertilizer F2 = 50% organic, 50% chemical fertilizer F3 = All organic fertilizer
20. Physiological characteristics of rice leaves at flowering stage as influenced by manure and density D1: 7.5 hills/m2; D2: 13.5hills/m2; D3 : 19.5hills/m2
21. Nitrogen accumulated before flowering stage and during the grain-filling period (GFP); N remobilized from vegetative tissue; leaf and grain N content; total N accumulated at maturity; and N harvest index (NHI) of 2 irrigation methods in 2 rice cultivars (Liangyoupeijiu and Eryou 7954)
22. Effect of SWD on tiller composition and productive panicles
28. Physiological characteristics of rice leaves as influenced by SRI * Means followed by different letters are significantly different at the P = 0.05 level according to Duncan’s Multiple Range Test.
29. a c b b Effect of transplanting density on leaf nitrogen content under SRI CK = 25 hills/m2; D1 = 7.5 hills/m2D2 = 13.5 hills/m2D3 = 19.5 hills/m2
37. “SWD” = Three Shallows – transplanting, when spraying with insecticide, and during booting-floweringstage Three Wets - tillering, panicle initiation, and during milk grain-mature grainstage One Dry - tiller control
