Over these years, by the methods of systematical monitoring, regular surveys, field investigation, rice blast resistance identification, experiments and meteorological data analysis, the study on comprehensive prevention and control of rice blast in Nanchong City was conducted. The results showed that the rice varieties more sensitive to blast had a higher incidence of severe blast disease. Replacing,varieties with different source of resistance every three to five years and reasonable variety distribution can effectively reduce the prevalence of rice blast. Appropriate treatment of infected rice straw and pathogen, seed disinfection, seedling disinfection, and pesticide application at transplanting and etc. can delay blast occurrence and reduce the damage caused by blast. By analyzing the blast control efficiency of pesticides applied at different growth stages, we found that best control efficiency against blast was achieved by spraying pesticide twice during the whole growth stage, once 3 d before transplanting or 10 d after transplanting; and once at initial heading stage. Spraying 525 g/hm^2 75% tricyclazole was proven to be the best dosage for blast control. However, 375-450 g/hm^2 75% tricyclazole is enough if the blast incidence is not severe, or the rice varieties are slightly susceptible to blast.The control efficiency against leaf blast between 4% kasugamycin and 20% tricyclazole had no significant difference, but was significantly higher than that of 100 billion spores/g of Bacillus subtilis. The control efficiency against neck blast had no significant difference among 4% kasugamycin, 20% tricyclazole and 100 billion spores/g of B. subtilis. 450 g/hm^2 75% tricyclazole had better control efficiency against neck blast than 2 250 g/hm^2 2% 800 million spores/g Jinggangmycin-wax bud bacteria SC, 1 050 g/hm^2 41% kasugamycin-isoprothiolane WP and 900 g/hm^2 41%kasugamycin-isoprothiolane WP. The frequency of severe blast incidence in Nanchong City has reached 50% since 1997. The rice blast disease has been effectively controlled by comprehensive prevention and control technology, reducing the production loss to less than 2%, and pesticides by 4 523 t in total. In 2014, 327000 t rice grains were approved as pollution-free, green and organic agricultural products, indicating that the blast control measures produced great economic, social and ecological values.展开更多

文摘Objective To investigate the current status of life stress and hypertension among couples of childbearing age across diverse economic regions in China,and to explore relevant influencing factors.Methods This study was a cross-sectional study,with subjects from the"Research on the standardized system of comprehensive prevention and control of birth defects based on preconception-prenatal-postnatal whole chain",From February to May 2021,urban and rural couples of childbearing age(18-49 years old)from Beijing,Henan,and Gansu provinces were enrolled,representing the eastern,central,and western regions of China,respectively.The detection rate,cognition and control of hypertension in the general population,as well as the detection rate of hypertension in different genders and regions were analyzed.Subjects were divided into hypertensive group and non-hypertensive group based on whether their blood pressure was≥140/90 mmHg(1 mmHg=0.133 kPa),and the general clinical data of the two groups were compared.Subjects were also divided into prehypertension and hypertension group and normal blood pressure group based on whether their blood pressure was≥130/80 mmHg,and the general clinical data of the two groups were compared,with subgroup analyses conducted by gender.Multifactorial logistic regression model was applied to identify factors associated with prehypertension and hypertension in both males and females.Results A total of 1942 couples of childbearing age,comprising 3884 individuals,aged(29.8±5.2)years were enrolled,with 1942 males(50.0%).The overall hypertension detection rate was 6.3%(246/3884),with a detection rate of 10.5%(203/1942)in males and 2.2%(43/1942)in females.The hypertension detection rates in Beijing,Henan,and Gansu were 6.2%(92/1482),11.6%(139/1200),and 1.2%(15/1202),respectively.The overall detection rate of prehypertension and hypertension was 40.5%(1574/3884).Multifactorial logistic regression analysis showed that life pressure factors had no effect on female blood pressure levels(P>0.05),while a significant or high level of life/work pressure was a risk factor for prehypertension and hypertension in males(0R=2.30,95%CI 1.06-4.99,P<0.05).Conclusion The detection rate of prehypertension and hypertension among young couples of childbearing age in China is high,and the awareness and control of hypertension are poor.There are sex differences in the relationship between life pressure and blood pressure levels.Comprehensive consideration of individual living environments and mental health factors is crucial in blood pressure management.Measures to reduce life stress and enhance mental resilience should be implemented to address this public health issue.
