秋玉米生育特点及高产栽培技术

秋玉米栽培是实现多元化熟制重要途径。生育特点为营养体小，单株生产力较低，生育期比春玉米短20d，比夏玉米短7d。但前期生长发育快，抽雄后灌浆成熟慢，虽“慢－－快－－慢”速率变化。要获得秋玉米优质高说，栽培选用早中熟紧凑型抗病良种，7月15日前播种，确保9月10日前抽雄，收获密度5000株／667m^2，采用“促－－促－－促”施肥，及时防治病虫草害，推迟带秆收获。

Differentiation of hog cholera and bovine virus diarrhoea viruses in pigs using monoclonal antibodies

Monoclonal antibodies against hog cholera and bovine viral diarrhoea viruses were assayed on organ tissue sections of experimentally infected animals. The animals had been infected simultaneously with both viruses. The antibodies were tested using an indirect immunofluorescence test and an indirect enzyme immunoassay with a biotin/streptavidin/peroxidase detection system. A polyclonal hyperimmune serum was used as a control in direct immunofluorescence tests. Both techniques based on monoclonal antibodies were more sensitive and more specific than the conventional test, the enzyme immunoassay being more sensitive than the immunofluorescence test. Small amounts of BVD viral antigen were demonstrable with monoclonal antibodies in most organ tissues.
