Effect of Growing Medium on the Physiological Characteristics of Organic Rice Seedling

Article Preview

Abstract:

An experiment was conducted to study the effects of different growing mediums on rice seedlings. Nine kinds of growing mediums were used: AN, AR, BN, BR, CN, CR, DN, DR, mixtures of decomposed chicken feces, soybean cake, plant ash and two organic acid (N and R) with different proportions; CK, a commercial growing medium (XinZu), used as control. Chlorophyll content, soluble sugar, peroxidase activity and root vigor of rice seedlings were analyzed. Results showed that rice seedlings in BR were stronger, with higher contents of chlorophyll, soluble sugar and peroxidase activity. The root vigor of rice seedlings was enhanced in BR. It was indicated that BR could be used successfully as growing medium for organic rice seedling.
