A section of a node of the station is a section with an arch roof and a straight wall of three underground floors, a first underground floor is a station hall floor, and a second underground floor is a platform floorof a subway line A and a third underground floor is a platform floorof a subway line B; and directions of the subway line A and the subway line B are orthogonal. Second lining structures of the first and second underground floors are firstly constructed, and after a shield tunneling machine is pushed through the station, the structure of the third underground floor is constructed by a reverse construction method. Thus, the present disclosure is conducive to improving the efficiency of overall construction, guaranteeing timely tunnel construction completion of two lines and hence timely track construction completion and electricity wiring completion.

High-energy composite peptide selenoprotein nutrient solutions, preparation methods and applications thereof enable crops to access selenoprotein nutrients. The nutrient solution includes selenium-containing materials, proteins, minerals, vitamins and natural energy ores, etc. Through protein enzymatic treatment, synthesis of peptide selenoprotein complex, energy treatment, complexation reaction and fortification, etc., the high-energy composite peptide selenoprotein nutrient solution is prepared, and can be widely used in the development of various kinds of selenium-rich agricultural products (including various kinds of grain crops, vegetables, fruits, fungi, wild plants, sea foods, animal meats, herbs, etc.). The mother liquor of high-energy composite peptide selenoprotein nutrient solution is diluted with water by 6000 to 8000 times; in the different growing period of crops, irrigate and spray the nutrient solution to the roots and foliages of crops, generally spraying 3-6 times, to get the selenium-rich agricultural products that can meet the standards.
