ANALYSIS METHOD OF ACCOUNTING EFI CROWN ON TESTING needles Annual sprigs

摘要

1. A method for analyzing accounting crown spruce twigs annual testing needles, comprising selecting an accounting fir tree and its whorl, then the first order branch is selected within the selected monitoring the whorl geodetic direction of its stem, with the stem end of the basic sample is cut in the form of branches for analysis of its water-holding ability, after cutting each sprig placed in a container for transportation, and then cut all branches in the laboratory are weighed several times with drying in ambient conditions until constant ma sy, characterized in that after determining the accounting tree ate selected geodetic direction, then adjustment accounting tree ate in a specified geodesic direction selected branch of the first order in the parts whorls or all whorls define retrospective age selected in whorls of branches starting from a terminal escape from accounting spruce wood, after cutting with the cutting height at the current time and non whorls, and subsequent transport of each cut branches in a separate container, in vitro slice nnye sprigs weighed to record in the observation time log elapsed after cutting each branch before the weighing, then divide each twig on petiole and needles sample and the stalk and needles sample was also weighed indicating the measurement time point, and after repeated weighting petioles and sampling needles to cut branches with drying them indoors until a constant weight was counted the number of needles in each sample after a constant weight at samples of needles from the measured value of the current
