METHOD SAMPLE Biochemical analysis of floodplain meadow grass on the small river

摘要

1. A method of biochemical analysis of samples on flood grass meadow small river, comprising a selection portion flood meadow grass with the test, then at the site downstream of the small river or in its inflow characteristic places mark out at least three cross-sections of measurement in the transverse direction along each cross-section mark out at least three test areas on each side of a small river or its tributary, after marking the received measured distance from the origin on one side of a small river or a tributary to the test plots centers to ohm, the measured height location of the center of each test pad from the surface of a small river or its tributary, and after cutting the sample grass subjected to the tests and the test results reveal patterns distance impact along each cross-section, the height of the test plots on the water's edge on the biophysical and biochemical indices of samples grass, characterized in that after the test samples cut grass floodplain meadows on biophysical indicators by weight and drying time, depending on the topography parameters in target ah measurement portion of the dried sample is taken for digestion and subsequent biochemical analysis of at least three biochemical substances: nitrogen, phosphorus and kaliya.2. A method of biochemical analysis of samples on flood grass meadow small river according to claim 1, characterized in that a portion of the dried sample is taken for digestion and subsequent biochemical analysis of approximately from the middle of the vessel in a paper bag weight not less than 100 g to form at least three times the reserve ash weight 1.5-2.0 g after natural drying further soak
