The intangible cultural heritage of south Hubei is rich in profound regional cultural connotations.By integrating such cultural heritage into ideological and political education of teachers'college,it not only helps its inheritance and protection,but also enriches the forms and contents of education,and promotes the innovative development of ideological and political education.In this paper,the integration of the tea-art creation process of green brick tea in southern Hubei and the practice of ideological and political education in teacher education major is selected as a study case,to deeply analyze the integration mechanism.The following integration strategies are proposed:combining ideological and political theory with practice,and adding courses related to tea culture;strengthening the construction of ideological and political practice bases,and enhancing the professional competence of the teaching team;building a"trinity"collaborative training system to ensure the smooth implementation of ideological and political education practice. 展开更多

To understand the genetic characteristics of a new photoperiod-sensitive genic male sterile line Mian 9S, some reciprocal crosses were made between Mian 9S and six indica rice materials, Yangdao 6, Luhui 602, Shuihui 527, Mianhui 725, Fuhui 838 and Yixiang 1B. Genetic analysis results suggested that the photoperiod-sensitive genic male sterility (PGMS) of Mian 9S was controlled by a single recessive nuclear gene. Thus, the F2 population derived from the cross of Yangdao 6/Mian 9S was used to map the PGMS gene in Mian 9S. By using SSR markers, the PGMS gene of Mian 9S was mapped on one side of the markers, RM6659 and RM1305, on rice chromosome 4, with the genetic distances of 3.0 cM and 3.5 cM, respectively. The gene was a novel PGMS gene and designated tentatively as pms4. In addition, the application of the pms4 gene was discussed. 展开更多

This study explored the effect of perceived social isolation on the mental health of college students during the high-risk period of COVID-19 transmission in Hubei,China and the role of social support from online friends in alleviating this effect.The questionnaire responses of 213 college students from four universities in Hubei were included.Measurement and structural models were constructed using structural equation modeling.The findings revealed that perceived social isolation while under home quarantine was a negative predictor of the mental health of college students in Hubei.Low social support from online friends may lead to a relatively strong relationship between perceived social isolation and mental health in these college students,whereas high social support from online friends may lead to a relatively weak relationship between perceived social isolation and mental health. 展开更多

This paper examines the current status and development dilemma of the children’s folk sports culture in the junction area between Chongqing and Hubei with reference to relevant literature.After the literature review and summary,the study finds there are several factors restricting the inheritance and development of the children’s folk sports culture in the area,including insufficiency of theoretical analysis,weak public support in cities,blind imitation of modern sports culture,and absence of policy support.To address the above problems,we put forward several suggestions to promote the inheritance and development of children’s folk sports game culture.First,we should focus on the theoretical research and cultural dissemination of children’s folk sports culture.Second,we should improve the basic rules of children’s folk sports games.Third,importance should be attached to government support in developing children’s folk sports game culture.Fourth,we should ensure the continuation and inheritance of children’s folk sports culture via school activities.Finally,we should carry forward children’s folk sports culture and explore ways to develop excellent cultural tourism. 展开更多

A photoperiod-sensitive genic male sterile (PGMS) rice was found in 1973 as a spontaneous mutant of Nongken 58, a japonica variety. Pollen fertility of Nongken 58s (N58s) is completely sterile when grown under long-day conditions, whereas fertile under short-day conditions. This PGMS was found to be controlled by one or two recessive gene(s), of which one gene(pms)was linked to a marker gene(d-1) on chromosome 5. In order to identify a more precise location of the pms, we analyzed the populations of BCFand BCFof N58s//N58s/KL211(v-10, virescent) and N58s//N58s/KL520 (gh-1, gold hull). The marker genes v-10 and gh-1 are located on the flanking region of d-1. The F, plants of two crosses were fertile. The number of fertile and sterile individuals in BCFfit 展开更多

The background of this article takes place after modern China.It is an essential change in the history of the Chinese salt industry that Sichuan salt supplies to Hubei.Sichuan salt jumped out of the original sales range,sold in Hubei.Since then,Hubei has become the most essential selling place of Sichuan salt,which continues to affect the economy of Sichuan.The War of Aid to Hubei was an inter-regional war in the warlord era.In order to realize“Local governance of Hubei”,the exploiting warlord Wang Zhanyuan was expelled.Sichuan chose to send troops,which economic factors are significant.Mainly,the Sichuan salt played a crucial role in it.Through the study of this problem,we can see that the economic factors in modern times occupy an essential position in the competition of warlords and promote the progress of history. 展开更多
