    The taxonomic status, damage status, biological control and anti-bacteria mechanism of Chinese cabbage clubroot disease were reviewed. Some strains from fungi, actinomycetes and Bacillus as biological pesticide against Chinese cabbage clubroot disease were studied by the researchers in the world. It had been reported that many Streptomyces had preventive control effects on clubroot disease, which needed further research and development. The first step of the disease cycle in the cruciferous vegetable host was the germination of dormant spores of Brassica brassicae. When it entered the host tissues, the zoospores would be the main damage form, and there was also a short asexual cycle stage, so the disease cycle was complex. Inhibiting dormant spore germination could be one of the main method to control club-root disease. Taking dormant spores as a targeting point to control Chinese cabbage clubroot disease had become a hot spot of interests from experts in various countries.

    Twenty japonica varieties with good quality and high efficiency were initially screened out among 145 collected varieties （lines）,and their growth period, yield and components, rice quality and comprehensive resistance were studied and analyzed in the northwest of Hubei. The results indicated that Yongyou 6763,Yongyou 4949,Yongyou 7053,Yongyou 1526,Yongyou 6760 and Nanfan 1605 had good yield potential and good comprehensive performance, which could be cultivated in the northwest of Hubei. The yields of Yangyujing No.2,Ning 5718,Nanfan 1610,Xu 32646,Yanjing 16,Yangjing 1612 and Wankenjing 372 were relatively high,and there were not obvious defects, so it was necessary to investigate the annual performance of these varieties in the northwest of Hubei. Huajing 295 and Wuyun 5020 had good yields, but their growth period was too long, so the seeding time should be appropriate. Sidao 14-211 and Xunong 33202 had high yields and good appearance, but their banded sclerotial blight was severe and lodging resistance was general, so it was not suitable for planting in areas with serious banded sclerotial blight. Shengdao 20, Huajing 8 and Yongyou 2640 had certain yield potential, and their growth period was suitable, but they had defect on lodging in the extreme weather of the maturation stage, so further test and demonstration was needed.

    Genetically modified（GM） science is not a one-way top-down knowledge transfer from professionals to the public. Different people have different degrees of acceptance of genetically modified science. The GM science questionnaire surveyed in different regions and ages in Hubei Province in 2018 is analyzed to explore the differences in the effectiveness of genetically modified science in different populations. The results show that the science effectiveness of different populations is different. Age, education level, region and other factors are factors that affect people's cognition.

    Based on the behavior of farmers' borrowing for the empirical analysis, the impact of rural household factors on the development of rural inclusive finance were analyzed by using the national fixed observation point survey system from 1986 to 2009. The results show that the area of cultivated land, whether it's a village cadre family and the degree of education play a positive role in promoting the household borrowing activities; while the family farming and production activities, family per capita annual income, non-agricultural income, informal borrowing quota and cash holding at the end of the year has a negative impact. In this regard, we should accelerate the reform of agricultural land circulation, expand the arable land area of farmers, use the advantages of Internet technology, expand the network of rural social relations, increase financial input, improve the overall quality of farmers, reduce barriers to entry, and guide the transformation of informal financial organizations to better promote the development of rural inclusive finance.

    In the context of the promulgation and implementation of the Charity Law, the QX village was investigated on the spot, using the literature method, the questionnaire survey method and semi-structured interview method to research in the cognition status, participation awareness, responsibility of the current resident population and consciousness and action trends of QX village. From the current situation of charity awareness in QX village, it is found that due to the small propaganda of the relevant state departments, the small amount of tax incentives limits the enthusiasm of citizens for charitable donations, etc., there are single ways of charitable donations and passive donations, citizens have a strong sense of traditional charity, lack of awareness of philanthropy and other issues. In response to these problems, we proposed ways to expand charitable donations, put an end to the behavior of leaders to encourage donations, establish a modern sense of charity, strengthen the publicity of charities in relevant departments, and establish and improve the supervision mechanism of charitable activities, with a view to providing reference for the sustainable development of charities in China.
