TESTING METHOD OF PLANT COVER ON AREAS OF PRODUCT PIPELINE ROUTE Russian patent published in 2013 - IPC G01N33/46 A01G23/00 

FIELD: agriculture.

SUBSTANCE: method includes the allocation of land areas of the route by the presence of plant cover in the form of grasslands and shrub vegetation. On the product pipeline route the areas with the test woody vegetation are selected. The distances between the observation sections at each selected land area are taken along the course of the product flow in the product pipeline, starting from the first observation section. On each land area with shrub vegetation the longitudinal axial line of the product pipeline is taken as the reference point of distance between the test sites in each observation section. Along each observation section at the sites with woody vegetation with in the absence of technological road, at least three test sites are marked out, and the middle test site is located on a longitudinal axial line of the product pipeline. In the presence of technological road and its location next to the product pipeline at one observation section at least four test sites are taken, and two test sites are located on each side of the technological road. If the technological road is located on the edge of the protection zone of the product pipeline, at least four test sites are marked out, but with the unspecified location with respect to the longitudinal axial line of the product pipeline. At each test site from wood shoots of the greatest height at least three shoots with the regularly shaped trunk with a large diameter near the root collar are selected and cut, indicating the species and measuring the height of each of at least three large tree shoots. Then the geometric arrangement of buds is measured the on the trunks of cut shoots, and with the measured values of the geometric parameters of buds location in each test shoot using the statistical modeling the regularity of shoot growth during the growing period from the beginning of budding to the moment of cutting of the tree shoot is determined. The environmental quality of woody plant and location of its growth is judged on the maximum relative error of found statistical models.

EFFECT: method provides ease of vegetation testing growing at route areas of the product pipeline for environmental and technological monitoring.
