Abstract: The contents of available N, K in the different growth stages of later-rice under different patterns of straw returning to field (SRF) were tested respectively in the experiment. The results indicated that the patterns of SRF siginificantly influenced the contents of NH4+-N in soil and unconspicuously influenced the available K contents of soil and NO3--N content of soil. The content of available NH4+-N under conventional tillage with high stubble (CTHS) was 40.8% and 36.7% higher than that under zero tillage with high stubble (ZTHS) and that under zero tillage with covering straw (ZTC), respectively. The available K content of soil under CTHS was 7.5% and 2.0% higher than that under ZTHS and that under ZTC, respectively. CTHS could improve rice growth, increase the content of chlorophyll, make full use of light energy, and enhance photosynthetic rate. The yield of CTHS was 5.8% and 9.0% higher than that of ZTHS and that of ZTC, respectively. So in conclusion, CTHS is the optimal pattern for local area.
