Bulletin of Gulistan State University
This research provides an ecological and faunistic analysis of research results on Collembolas in the Parkent district. 40 species of collembolas have been identified in apple orchard, wheat agrocenoses and surrounding ecosystems. The study revealed the following pattern: agrocenoses of apple orchard and wheat are much poorer by collembolan species than those in natural communities. Thus, in the agrocenoses, 29 species of collembolas were noted (6980 specimens per 1 m2). In natural communities – 40 species respectively (12386 specimens per 1 m2 of soil). The most densely populated by collemboles horizon of the surface layer (10-20cm).

The epitaxial layers of the (Si2) x (GaP) 1-x solid solution were grown from the liquid phase. It was shown that semiconductor compounds A3B5, when dissolved in metallic solvents, at temperatures below their melting points, are found mainly in the form of molecules and do not break up into separate atoms. The emission of red light was observed when a forward bias of 8-12 V was applied to the nGaP-n+(Si2) x (GaP) 1-x structure, which indicates the energy level formed by silicon molecules in the forbidden zone of gallium phosphide. From the photoluminescence spectrum of the (Si2)x(GaP)1-x solid solution, the …
