Method of assessing the thinning state of grape plantation

Abstract

The article considers the resources saving method for determining the thinning state of grape plantations. For its substantiation there are fulfilled selected accounts with intervals via 1, 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20 rows. The accuracy of accounts is determined by the difference of thinning state indicators in plantations, obtained in selected rows and in every row. It is revealed that in the course of increasing the interval between accounting rows the difference becomes more gradually. In the course of27-times observation, during increasing the interval from one to eight rows, the deviation of the sign increases on the average by 1 %, at further raising - it decreases. At the deviation of the sign till 5 % the account must be conducted after five rows at the sixth one.
