Odgovarajuća vlažnost u rasadniku mora se podržavati tokom čitave vegetacije, a provođenje zaštitnih mjera pravovremeno, brzo> i efikasno. Iz naprijed izloženog nameće se zaključak, da bi se o spomenutim iskustvima kod izbora zemljišta i lokacije rasadnika trebalo voditi računa, usmjeravajući ih prema opisanom izlaganju. Razumljivo je da treba u rasadniku nastojati proizvoditi što punodrvnije i veće sadnice, ali da to ne bi trebalo biti jedino mjerilo kod odlučivanja kakvih kvaliteta (provincijencije) sadnice će se upotrebiti za plantažiranje na nekom tipu zemljišta. THE CHOICE OF SOIL AND THE LOCATION OF POFLAR NURSERT SUMMARY Presenting his experiences gained in the choice of soil and placing of Poplar nurseries, the author comes to the following conclusions: the nurserv should lie on a flat terrain and in the proximity of good roads; it should have a safe and permaent possibilitv of irrigation; it should toe protected against hail and situated in the vicinity of the planting site; it should be established on a convenient site (similar to the one to be planted). Seedlings obtained on a soil with an excess of nitrogenous manures display large lumena and a spongy structure, and therefore they are less resistant to diseases. The same happens also in places with longJasting stagnant underground water where the seedlings become physiologically weakened, and if additionally clipped they become susceptible to infections (Dothichiza populea). |
