Abstract

The cultivation of poplars supplies some of countries demands of wood. Thus, they have an important role to reduce the pressure on forests. The poplar plantation along the Zanjan - Rood river banks are in valuable. This project was prepared and executed to get information about the structure, variety and growth rate of the poplar plantations. At first, after exploration of the area, the map of the poplar cultivation in the area was prepared. There are 98 discrete poplar plantations between the village of Kooshkan and Nickpay. Then, on the basis of a statistical plan, 56 plote 300m2 in area were picked through the area by the" PPS" method. Various data were collected from these. After analysis and processing of the information variable were calculate regression charts provided, and these results were concluded:- 90% of poplars plantation consist of the two species of P.nigra var "pubescens" (60%) and P.alba cv "shirazi" (30%).- The average volume of these plantations is 270m3 and about 1100 tree per hectare with a diameter grater than 8 centimeter. The shortage of young trees in the area is very obvious, and the future of the cultivation of poplars the area is danger. The trees in the P.alba plantation have a better condition than these in the P.nigra plantation regarding features like, diameter, height, cylindrical form, elongation of trunk, few number of branch excrescence of the trunk, form and thickness of the bark, ...- The trees of the P. alba have 2.5m3 of volume with the diameter of 50cm and height of 25m, while trees of the P.nigra with these dimensions are just 1.6m3 in volume.Totally, the area is capable of being converted to a plantation of poplars center. It is necessary to in traduce the new method of cultivation, and agriculture, by through survey and coherent planning and management. It is also need to give the urgent supports of poplar farmers in long time plans.
