The results of the experiment and demonstration show that the specialty fertilizer can increase yield by 23.5%, 385.5 kg and 615.6 RMB Yuan per hectare than the common fertilizer (ammonium phosphate+urea+potassium chloride) or increase yield by 7.8%, 177.1 kg and 240 RMB Yuan per hectare than the same amount of ammonium phosphate.
1000kV main transformer is the one of crucial equipment of UHV test and demonstration project, its quality is directly concerned for successful construction and operation of the project, therefore it is very important to research and develop 1000kV main transformer with high quality.
Based on the information of wheat production for more than 40 years in thetypical loess tableland area including the north highland of Qianxian county,Yongshao coun-ty in close connection with test and demonstration results in the years of 1986—1992 in Za-ozigou watershed,wheat variety improvement was analysed using average rate and produc-tion indexes,reaching 23. 21%.
With the combination of investigation, analogy, simulation, field test and demonstration during 1987-1999,this paper is concerned with the land reclamation and ecological rehabilitation in ATB mine within Pingshuo,Shanxi province.
A field trial and demonstration, and indoor and outdoor tests showed that soil fumigation with SMDC (32.7%) at the rate of 50 ml/m 2 can effectively control the common weeds in tobacco seedbeds, its controlling effect being comparable to that of methyl bromide (86.1%), Compared with control by hand, soil fumigation saved labor by 84.3%.
By trial and demonstration in the different area field, comparing average yield with local popular variety, increased degree attained significant at 5% and 1% level, It will have wide applied prospect in the winter wheat region of dry field northern china demonstrating and popularizing.
The construction of dam system in Jiuyuangou valley since 1953 undergoes about four stages including experimental Demonstration, development, reconstruction and improvement. It has constructed 263 blank of dam reservoirs, 282 hm 2 of silt lands and 20 085 00 m 3 of silts have been controlled.
The study was carried out on the experimental demonstration base for industrializing production technique of Agropyron during the years from 2002 to 2004 in the West Sunite Banner, Xilingol league, Inner Mongolia.
Making the small watershed as a unit, the experimental demonstration study of eco-environment construction to the medium scale and the scientific assessment of eco-rehabilitation's environmental effect and so on should be enhanced.
