Resource Utilization of Rice Straw and Its Effect on Soil Fertility
Abstract: The characteristics of rice straw decomposition in the process of resource utilization and its effect on soil fertility and crop yields were analyzed based on nylon bags method of field trials. The results showed that rice straw decomposition ratio increased with time increasing and rice straw decomposition rate was bigger in the early stage than that of late stage. The decomposition effect of rice straw in farming is better than that of no farming. The returned rice straw not only improved the soil physical and chemical properties, but also in-creased the soil nutrient content and rape yields. The study can provide the basis parameters for rice straw resource cycle utilization and for improving agricultural eco-environment.
