Construction and evaluation of an efficient rice straw collection,storage and transport system at scale:A case study of Henghu reclamation farm in Jiangxi Province
This study focuseed on the Henghu reclamation farm in Jiangxi Province with the aim of enhancing the com-prehensive utilization of straw and improving its collection,storage,and transportation system.The study analyzed the process of rice straw collection,storage,and economic cost and develops a suitable rice straw collection,storage,and transportation system for more than 10000 tons.The results were as follows:① The baler can be admitted to the field if the water content of rice straw was ≤20％on the 4th day under natural conditions.② To ensure the stability of the qual-ity of the rice straw and safe storage,the field operation parameters of the baler.This included maintaining a density of straw bales≥150 kg·m-3 and an impurity rate ≤5％.③To enhance the stacking and storage capacity of the rice straw yard,optimizing its design while ensuring the safety and stability of the rice straw.④ As storage time increased,the de-gree of rice stalk corruption gradually increased.The cellulose content coefficient of variation was the largest.Additional-ly,the non-film cover coefficient of variation was higher than that of the film cover.The bottom layer coefficient of varia-tion was also higher than that of the top and middle layers.⑤ An economic model for rice straw collection,storage,and transportation should be established.This model should evaluate the economic cost of the rice straw collection,storage,and transportation system.The total economic cost of the centralized mechanical collection,storage,and transportation model was approximately 290 yuan·t-1.The study results offered technical support for the creation of an effective sys-tem for collecting,storing,and transporting straw and for the development of the comprehensive utilization of the straw industry in Jiangxi Province.
