Abstract

Abstract: In order to clarify the decomposing characteristics of different rates of tobacco straw and their effects on rice yield. In this study, one field experiment was conducted. Then, the decomposition rates of tobacco straw and rice yield among different treatments were analyzed. Meanwhile, the quantitative relationship between the external input of carbon and nitrogen ratio and rice yield was discussed. The results showed that： the decomposing characteristics of the tobacco straw in all treatments were fast in the early stage and slow in the late stage. At the 5th day, the amount of decomposed tobacco and the average daily decomposing amount were reached the maximum, which were 0.87 g and 0.29 g/d, respectively. The cumulative decomposing rate of tobacco straw also showed a similar trend, and the cumulative decomposing rate of tobacco straw in the whole rice season was 42.31%. However, there was not significant different for the total and daily decomposed amount of tobacco straw among all treatments, but the cumulative decomposing rate of the semi-returning treatment was higher than the equivalent and 1.5 times returning. The correlation between the input of carbon-nitrogen ratio and rice yield could be fitted by the quadratic curve equation. Moreover, it indicated that the reasonable input of carbon-nitrogen ratio was 10.1, and the corresponding maximum yield of rice was 10.4 t/ha. Therefore, in the rotation of tobacco and rice, the reasonable carbon-nitrogen ratio input was one key pattern to improve rice yield, although the characteristics of decomposing under different amounts of tobacco straw was similar.

Key words: Tobacco straw, Decomposing rate, Rice yield, Carbon-nitrogen ratio
