摘要： The present disclosure provides a method for two-phase partitioning production of a medium-chain fatty acid (MCFA) by dry anaerobic digestion. In the present disclosure, due to a slow heat transfer of the dry anaerobic digestion, a same dry anaerobic digestion device is naturally divided into two phases, and the MCFA is synthesized while producing electron acceptors and electron donors in the same dry anaerobic digestion device. Meanwhile, the dry anaerobic digestion device is provided with a high-efficiency decomposing microbial inoculant on an upper part and inoculated with sludge having a carbon chain extension function on a lower part. In this way, a material residence time is regulated, and cycles of hydrolytic acidification and carbon chain extension are shortened, thereby achieving the high-value conversion of agricultural waste while increasing a conversion rate of organic acids in the dry anaerobic digestion.

摘要： The present provides methods for assessing comprehensive risk of drought and flood disasters on apple. The method adopts an optimal curve relationship between an apple yield reduction rate and drought and flood indexes and considers two disasters of drought and flood at the same time to determine the weather index threshold value under the threshold values of different yield reduction rates, meanwhile, builds comprehensive risk index models of drought and flood disasters from risk of disaster-causing factor, sensitivity of disaster-pregnant environment, vulnerability of disaster-bearing body, etc. using terrain, rivers, vegetation, apple planting area, and water profit and loss ratio, etc., and determine a premium rate according to a level of disaster risk to obtain insurance rates and premiums in different regions according to local conditions, thereby formulating a design scheme of insurance products suitable for local conditions, which has great advantages compared with a traditional single-disaster weather index insurance.
