<正> Abstract: Field experiment was carried out to nitrogen release characteristics of rice controlledrelease fertilizer (RCRF) coated with natural and half natural high molecular materials, and to thereofeffects on the nitrogen uptake and yield of early and late hybrid rice from 1999 to 2000, with urea ascontrol.
<正> Abstract: According to clinical and pathological observation in infectious serositis of duck, the mainsigns of this disease were diarrhoea, breathing with difficulty, head tremble and movement beyondcoordination. The pathological changes that had been found in 30 experimental ducks were fibrouspericarditis, hepatitis, and encephalitis.

<正> Abstract: Strain T_(02-25) was selected from approximately 30 rhizosphere isolates of Trichodermaspecies isolated from roots of crops. Its biological activity against Rhizoctonia solani was determinedfor the control efficacy to pepper seedling blight caused by R. solani in the field. The assay methodswere treating R. solani sclerotia by Trichoderma conidial suspension (10~6cfu ml_(-1)) and scattering

<正> The national biggest genbank of gingko germplasm has been established in Nanjing Forestry University andpassed certification in June 2002.It will not only offer the good substantial foundation to gingko breeding,butalso greatly promote gingko industrialization and bring enormous economic, social and ecological benefits.
<正> The breeders at Hunan Agricultural University recently have bred a series of new rice cultivars that areexpected to enhance the protein ingest capacity per capita of Chinese people. Assistant Professor Hong Yahui with other experts at Hunan Agricultural University adopt theembryo-soaking method to transmit the total DNA of high protein corn"Machihuang" into quality early indicarice 91-L.After several years'selection,they have bred five high proten rice lines from variations.
<正> On September 29,a grand centenary ceremony for the birth of Hunan Academy of Agricultural Sciences(HAAS) will be solemnly held in the Academic Exchange Center of HAAS.Leaders at all levels,honored guestsand friends will attend the royal celebration to discuss the development of Hunan agriculture.
