Application of Landfill Composed of Biogas Residue and Slurry in Cherry Production

In order to explore the effects of landfill composed of biogas residue and slurry on the improvement of soil nutrients and cherry fruit yield, three treatments： control （no landfill）, landfilling with biogas residue and water （BR）, landfilling with biogas residue and slurry （BS） were conducted in a cherry orchard. The results showed that compared with the control, soil water content around the landfills with a radius of 60 cm within 30 d was increased in BR and BS treatments. The poment- age of short shoots and the total number of shoots of cherry trees were also signif- icantly increased by BR and BS treatments; the cherry fruit yield per tree and the single-fruit weight in BS treatment were increased by 21.76% and 28.89%, respec- tively. In addition, BS treatment obviously improved the contents of soil organic matter, soil available nitrogen, s0il available phosphorus, soil available potassium and other nutrients. The positive effects of BR treatment on the improvement of soil nutrients and cherry fruit yield were lower than those of BS treatment, indicating that the combined use of biogas residue and biogas slurry as landfill can improve the soil water and fertilizer status in orchards, and thus can be promoted in the cultivation of fruit trees.

Application of Intensive Closed-type Float System in Tobacco Nursery

Due to the continuous low temperature during the early-nursery period in most tobacco-growing areas in Guizhou Province, the tobacco seed germinate slow-ly, the nursery period is prolonged, the quality of tobacco seedlings are not that good, the transplanting is delayed, etc. A comparative test of intensive closed-type floating-seedling system and conventional floating-seedling system was carried out in this study. The results showed that the intensive closed-type floating system could shorten significantly the nursery period; enhance the growth of tobacco seedlings;improve significantly the appearance of agronomic traits, such as number of leaves, stem height, stem diameter, fresh weight of leaves, etc; increase slightly the chloro-phyl content in seedlings. However, the root fresh weight and root vigor of seedlings nursed with the intensive closed-type float system were lower than that of seedlings nursed with the conventional float system. The intensive closed-type float system had a certain application potential in tobacco production.

Treatment of Dimethoate Aqueous Solution by Using Ultrasonic Airlift Loop Reactor

Ultrasonic airlift loop reactor （UALR） shows potential and wide application for wastewater treatment. In this paper the performance and efficiency of UALR in dimethoate degradation were presented. The effects of O3 flow rate, ultrasonic intensity and initial concentration of dimethoate on degradation rate were investigated. UALR imposed a synergistic effect combining sonochemical merit with high O3 transfer rate. The results showed that UALR not only increased degradation rate, but also was better than the simole sum of degradation by O3 and ultrasound separately. Under the operation conditions of O3 flow of 0.34 m^3·h^-1, ultrasonic intensity 3.71 W.cm^-2, and initial concentration of dimethoate at 20 mg·L^- 1, the degradation rate of dimethoate increased to 80%. UALR seems an advisable choice for treating organic wastewater and this process may have wide application prospect in industry.

Establishment and Preliminary Application of a Rapid Fluorescent Focus Inhibition Test (RFFIT) for Rabies Virus

The World Health Organization (WHO) standard assay for determining levels of the rabies virus neutralization antibody (RVNA) is the rapid fluorescent focus inhibition test (RFFIT), which is used to evaluate the immunity effect after vaccination against rabies. For RFFIT, CVS-11 was used as the challenge virus, BSR cells as the adapted cells, and WHO rabies immunoglobulin (WHO STD) as the reference serum in this study. With reference to WHO and Pasteur RFFIT procedures, a micro-RFFIT procedure adapted to our laboratory was produced, and its specificity and reproducibility were tested. We tested levels of RVNA in human serum samples after immunization with different human rabies vaccines (domestic purified Vero cell rabies vaccine (PVRV) and imported purified chick embryo cell vaccine (PCECV)) using different regimens (Zagreb regimen and Essen regimen). We analyzed the levels of RVNA, and compared the immune efficacy of domestic PVRV and imported PCECV using different immunization regimens. The results showed that the immune efficacy of domestic PVRV using the Zagreb regimen was as good as that of the imported PCECV, but virus antibodies were generated more rapidly with the Zagreb regimen than with the Essen regimen. The RFFIT procedure established in our laboratory will enhance the comprehensive detection ability of institutions involved in rabies surveillance in China.
