This paper introduced the breeding process, yield performance and characteristics, and the high-yield cultivation technology of new edible sunflower variety AR9-9293. The promotion of edible sunflower varieties and cultivation technology could achieve the effects of improving the level of the sunflower cultivation, promoting the development of rural and agricultural economy and increasing farmers＇ income, as well as positively promoting development of the society and adjusting agricultural industry structure.展开更多

In this paper, the mixotrophic cultivation of Tetraselmis sp.-1 in airlift photobioreactor is investigated. Firstly, the paper calculates the light attenuation in the mixotrophic medium, and sets the light attenuation model. Secondly, it uses the same dissolved oxygen coefficient (K d) of flask culture to select the aeration of bioreactor. Finally, it sets the growth kinetic model, production (chlorophyll-a and total lipid) kinetic models and substrate (glucose) consumption kinetic model of Tetraselmis sp.-1 in airlift photobioreactor.展开更多

This paper takes the Belt and Road Initiative for example,emphasizing the interpretation of the inheritance and development of Chinese culture so as to study the importance of Culture Self-Consciousness in Chinese Philosophy,in the context of English globalization. That is to say,this paper stresses the spirits and the stand of nation 's demonstration on pursuing peace,cooperation and sustainable development in the civilization continuity from traditional China to the contemporary China,with practical philosophic view.展开更多
