This paper reviewed and analyzed the current situations and influencing factors of the bilateral agricultural product trade development in China-ASEAN Free Trade Area(CAFTA),which has important practical significance for promoting the in-depth development of the free trade area and has guiding significance for precise policy *** on the status of import and export trade of agricultural products in CAFTA from 2013 to 2017,it constructed a trade gravity *** the aid of Stata 14.0 software,it explored major factors influencing the development of bilateral agricultural trade from the total amount of agricultural products import and export and Commodity Indexes for the Standard International Trade Classification,Revision 3(SITC Rev.3)agricultural product classification *** empirical regression results show that the GDP of ASEAN countries,the ratio of agricultural added value to GDP,and the per capita gross national income(GNI)measured based on the purchasing power parity(PPP)exchange rate have the greatest impact on agricultural product trade in CAFTA in the context of"the Belt and Road"(B&D).Based on empirical research,it came up with recommendations including adjusting the import and export structure of agricultural products,enhancing product competitive advantages,and implementing diversified markets.

Prochloraz diluents( 450 ×,475 ×,500 ×) were added with different concentrations of nano-titanium dioxide( Ti O2)( 0. 8%,1. 0%) respectively to prepare complex fresh-keeping agents,which were applied in the refrigeration of Dioscorea alata Lirm. sp. With rot index,weight loss rate,browning degree( BD),total soluble solids( TSS) content,malondialdehyde( MDA) content,polyphenol oxidase( PPO) activity and peroxidase( POD) activity,DPPH· scavenging rate as evaluation indexes,the preservation effect of the prepared freshkeeping agents on D. alata during the cold storage period was analyzed. The results showed that prochloraz added with nano-titanium dioxide significantly prolonged the storage life,reduced the rot rate and weight loss rate,and slowed the loss of pulp of D. alata. The preservation effect of complex fresh-keeping agent of prochloraz diluent( 475 ×) and nano-titanium dioxide( 1. 0%) was better than that of other treatments.

[Objectives]This study was conducted to discuss the change laws and relationships of the physiological indexes in green plums treated with nisin or 1-MCP in the cold storage process.[Methods]Different storage methods on the physiological and quality indexes of green plums were investigated through two kinds of different treatment methods(treatment 1:1-MCP+cold storage,treatment 2:nisin+cold storage),with rotten fruit rate,weight loss rate,yellow ripeness index,hardness,Vc content,titratable acid,soluble solids and peroxidase(POD)activity as the evaluation indexes.[Results]The storage method of treating green plums with 1-MCP combined with cold storage could delay the quality decline of green plums after harvest,while the effect of nisin treatment was slightly inferior.1-MCP treatment followed by cold storage could more effectively delay the senescence of green plums,delay the decrease of fruit hardness and soluble solid content to the greatest extent,and maintain the titratable acid and Vc contents at relatively good *** further reduced weight loss rate and rotten fruit rate,postponed the time of the peak of POD enzyme activity,and reduced the loss of nutrients in the fruit,thereby maintaining good commercial properties of the fruit.[Conclusions]This study plays an important role in the post-harvest storage,preservation and transportation,as well as the development of the green plum industry.
