Organic seedling matrix was mixed with brown loam soil and paddy soil in different proportions as culture matrix.The physical and chemical indexes of the matrix were detected.The growth trend of rice was observed.According to the effects of the complex matrix on sucrose metabolism related enzymes and soluble protein content,the optimal ratio of rice seedling cultivation was selected.The results show that the above ground dry weight can represent the growth trend of rice by principal component analysis.Select the optimal treatment T2(75%BS+25%OSS).The seedling matrix is better than other treatment groups,which is suitable for rice growth and good growth,and provides a theoretical basis for optimizing the growth conditions of indoor rice seedling.
