[The rooting and growing of fir cultures depending on the initial density]
1994
Mangalis, I. (Latvia) | Berzins, M. (Latvia)
Different measures of the increasing of the productivity of artificially renovated fir growths are analysed. The growing of resistant growths is the process which begins with the optimization of the initial density and continues with the purposeful regulation of the number of trees. Tree differentiation, their medium height, the average increasing of trees in thickness, the differences of the cross-section and the coefficient of stability are considered in the article. The rooting of cultures, the process of the thinning of a growth and the remaining process of trees are shown in the table 1. The evaluation elements of sixteen-year-old fir cultures with different initial density are given in the table 2.
