Claims (6)

1. A method of testing shoots of a woody plant, including taking prototypes, measuring the geometric parameters of each sample, measuring ultrasonic parameters of wood on the samples, characterized in that the sampling in the form of annual shoots is carried out at the end of the growing season, for example, at the end of September or in the month of October , then select the registration woody plant, cut the experimental samples of shoots near their base, mark the number of the tree and the number of the experimental sample on the butt end of each experimental shoot, after cut and labeled experimental shoots are sent for laboratory measurements, while the geometric parameters of each experimental shoot are measured by measuring the geometrical location of the buds and the dimensional parameters of the cut shoots, and after such measurements, the experimental shoot is divided, starting from the butt part, into segments and these segments are voiced ultrasound, according to the measured values of the geometric parameters of the location of the kidneys on each experimental shoot, statistical modeling reveals patterns of distribution kidney divisions along each shoot and according to these laws judge the ecological quality of the woody plant and the place of its growth. 2. The method of testing the shoots of a woody plant according to claim 1, characterized in that in the forest or on an area with woody vegetation, an accounting tree is selected, i.e. a tree that allows you to repeatedly carry out environmental surveys and experiments with annual shoots in other growing periods, and then inspect the crown for possible shoots as prototypes. 3. The method of testing the shoots of a woody plant according to claim 1, characterized in that the experimental shoots are divided into segments of at least 200 mm in length, while using an ultrasonic device to measure the propagation velocity of ultrasonic waves along the length of the experimental shoot, carry out all or part of the experimental shoots in one and the same point in time, for example, at the beginning and at the end of natural drying of the segments of the test samples, and then calculate the arithmetic mean values of the speed of ultrasound along the shoot along several segments, and the end IRS natural drying is determined by the permanence of the mass of each segment experienced escape. 4. The method of testing shoots of a woody plant according to claim 1, characterized in that statistical modeling reveals the pattern of shoot growth during the growing season according to the following statistical formula:

where L is the variable design shoot length from its base, mm; L ₀ - the initial (starting) shoot length to the moment of measurement, mm; t - time from the beginning of the growing season, days; and ₁ ... a ₆ are the parameters of the statistical model. 5. The method of testing the shoots of a woody plant according to claim 1, characterized in that statistical modeling reveals the pattern of distribution of the kidneys and the formation of nodes of the buds according to the following formula:

where L _j - variable design shoot length at the nodes of the kidneys, mm; j is the number of the kidney node, starting from the base, with j = 1, 2, 3, ...; and ₁ ... a ₁₄ are the parameters of the statistical model. 6. A method for testing shoots of a woody plant according to claims 1, 4, and 5, characterized in that according to the patterns found by statistical modeling, the ecological quality of the woody plant and the place of its growth are judged.
