[Methods] The spatial distribution pattern of diseased or infected plants was analyzed using the least square method, fre- quency distribution, aggregation index, m＊-m regression analysis and Taylor＇s pow- er law model. [Result] The field distribution of broccoli plants with clubroot disease tended to be aggregated distribution, m＇-m regression analysis showed that the el- ementary composition of the spatial distribution of diseased or infected plants was individual colony, the individuals attracted each other; the disease had obvious dis- ease focus in the field, and the individual colony showed uniform distribution pattern in the field. Taylor＇s power law showed that the spatial pattern of individual dis- eased or infected plant with clubroot disease tended to be uniform distribution with the increase of the density. On the basis of this, Iwao optimal theoretical sampling model and sequential sampling model were established, namely N =273.954 1/m- 59.698 5, To （N）=0.368 4N±1.926 8√N, respectively, it meant that when surveying N plants, if the accumulative incidence rate exceeded upper bound, the field can be set as control object; if the accumulative incidence rate didn＇t reach lower bound, it can be set as uncontrol field; if the accumulative incidence rate was between upper bound and lower bound, it should be surveyed continuously until the maximum sample size （mo=0.368 4） appeared, that was, the disease incidence was 15%, so the sampling number should be 684 plants. [Conclusion] The research results had very important instructive meaning for disease control.展开更多

However, students' apparent reticent behavior in English classes is found to become a common phenomenon in China. With the increasing importance of English speaking skills, there is a pressing need for teachers in universities to be aware of the reasons for student reticence, help students to adopt an active participatory role in class and provide them with more opportunities to practice their oral English.展开更多

The purpose of this paper is to explore the reasons for the differences in class participation between Chinese and American students from the perspective of cultural values. The learning behaviors of both Chinese and American students are described based on the author's observation and research. A questionnaire delivered to a number of Chinese and American students is then briefly analyzed. The paper focuses on five dimensions of contrastive values held by the Chinese and Americans, which lead to their different views about talk: high-context culture vs. low-context culture; harmony vs. confrontation; collectivism vs. individualism; obedience vs. aggression; face giving vs. facing saving.展开更多
