GIS and the fundamentals and methods of geostatistics were applied to regionalize the spatial distribution pattern of Available Potassium, Available Phosphorus, Available Nitrogen and Organic Matter in Jinghe Basin. The results showed that: 1 It is clearly founded that the spatial heterogeneity of the soil available nutrient in Jinghe basin, and the human activities had seriously impacted on the spatial...
In this paper, for improving the integrative controlling effect of Trichoderma harzianum, effect of 14 pesticides on T. harzianum was studied with growth rate method and the circle of inhibiting bacterium method. The results suggested that all 14 tested pesticides with different concentration showed different controlling effect on mycelia growth of T. harzianum. At the recommended concentration in...

In order to investigate abilities of anti-environmental interference of water evaporation retardants, a new kind of water evaporation retardants composed of 1-hexadecanol and nonionic surfactants was prepared in this paper, and effects of environmental factors on retardation of water evaporation of mixed monolayers were studied. The results showed that in comparison with monolayers of single component,...
A novel kind of the hydrochloric acid fume retardant was prepared with the long chain fatty alcohols and the nonionic surfactants in this work. The results showed that the film-forming materials could spread as monolayers quickly and spontaneously at the hydrochloric acid surface. The mixed monolayers exhibited considerably larger effective resistance to hydrochloric acid fume when the concentration...
