main harvest
3.To solve the problem of short growth cycle and low yield of summer-planting stevia in Jining city of the Shandong province, the main cultivated techniques after summer-planting stevia harvest were introduced for planting some vegetables, such as Chinese cabbage, radish, garlic, onion, cabbage and potato.
4.Sod activity (SOD-a) of main organs of peach, apricot, cherry, and nectarine which contained 15 cv. was detected in different phenological phases. In shoot cortex, SOD -a raised at first, then went down and raised a-gain in the period of pre budding (Ⅰ), young fruit setting (Ⅱ), fruit puffness (Ⅲ) and harvest (Ⅳ). SOD-a was the highest in Ⅱ generally;
5.It is an important that bacteria contaminated vaccine in the biologicals production.We collected 703 samples of cell culture, virus cultivation and harvest which were contaminated by bacteria during poliovaccine production within two years.We checked these samples by bacteriological method and antibiotics sensitivity tests were done.It shows that 1)the main contaminated bacteria come from staphylococci,bacilli and streptococci of environment in the poliovaccine production.2）It is effect that antibiotics to contaminated bacteria are doxycycline,albiotic,prescription 2,cefotaxime Na salt,gentamycin,neomycin,aureomycin and erythromycin.
