A method for measuring tree leaf growth dynamics in clean environmental conditions

摘要

1. A method for measuring tree leaf growth dynamics, comprising a substrate with a white surface laying on the bottom sheet is measured, and on the top sheet is applied a transparent map mosaic for the measurement, wherein the longitudinal axis of the sheet plant combined with a mosaic grid lines, and then through the transparent sheet with paletka mesh photographed after the picture is placed in the memory of a computer, and measurements of length and width of the sheet operate in cells of the grid in the zoomed image mosaic plant leaf, characterized in that on the side behavior rhnosti tree crown isolated local zone with similar sunlight, which is selected credential group leaves with marks, measurement parameters credential leaf performed during the growing season of days from bud leaves with photographing each accounting sheet, during a time vegetation performed repeatedly measuring account settings leaves, and then in the group on all user leaves taken at a local surface area of ​​the tree crown, statistical modeling reveal srednestat -terrorist laws of the dynamics of growth accounting leaves on individual parameters accounting leaves growing on the same local area dereva.2 crown surface. The method of claim. 1, characterized in that the tree crown at a convenient height measurements on the lateral surface of the tree crown isolated local zone with approximately the same illumination, which selected group of at least 10 accounts leaves, each note mark in the form of a piece of white thread tied to the base of the petiole on leaf, the local area selected around a circle
