Mitengo ndiyo nthawi yayitali padziko lathuli. Amatha kukhalapo padziko lapansi kwazaka mazana ambiri kapena ngakhale masauzande. Amapanga maselo atsopano nthawi zonse omwe amapangidwa ndi tsinde la mphete zakukula pachaka. Amathandizira kukhazikitsa zaka zamitengo. Akatswiri amati m'zaka zaposachedwapa, kukula kwa mitengo yambiri kwawonjezeka kwambiri. Kuthamanga kwake, zimatengera chilengedwe. Mukamabzala mitengo m'munda mwanu, kukula kwake kumatha kuchulukitsidwa posamalira bwino.
Monga anthu, mitengo imakula mwakhama akadali aang'ono, ndipo ikakula, ikucheperachepera, kapena kuyimiratu. Tiyenera kudziwa kuti padziko lapansi, mitengo yamitundumitundu imakula mosiyanasiyana. Nyengo ndi nyengo ndizofunikira kwambiri pantchitoyi.
Mitengo yomwe imakula msanga
Mitengo yomwe imakula kwambiri imakula m'malo osiyanasiyana padziko lapansi. Atha kugawidwa m'magulu otsatirawa:
- Kukula mwachangu - mchaka chimodzi amakula pafupifupi masentimita 200 (mthethe woyera, paulownia, msondodzi woyera, popula wakuda, mapulo asiliva, bulugamu, birch warty);
- kukula msanga - kwa chaka, kuwonjezeka kuli pafupifupi masentimita 100 (elm yovuta, spruce wamba, European larch, elm, sycamore, mtedza, wamba pine);
- Kukula bwino - masentimita 50-60 okha amawonjezedwa (Amur velvet, prickly spruce, common hornbeam, virgin juniper, mapulo wamunda, linden yasiliva, firasi ya Caucasus, rock oak)
Kwa mitundu iyi ya mitengo, zisonyezo zimawonetsedwa zomwe zimayamba kukula, mtengowo ukadali wachichepere.
Mitengo yomwe imakula pang'onopang'ono
Monga mitengo yomwe imakula msanga, palinso anthu omwe amakula pang'onopang'ono. Kwa chaka chimodzi amakula pafupifupi masentimita 15-20, kapena osachepera. Awa ndi peyala ya mtengo wa apulo, mtengo wa pistachio ndi thuja yakum'mawa, boxwood ndi cypress yosalala, msondodzi wobiriwira, mkungudza wa ku Siberia ndi mabulosi yew.
Mtengo ukangocheperachepera, umapeza thunthu lambiri. Izi ndichifukwa choti mitengo yakale imatenga CO2 yambiri motero imawonjezera unyinji. Zotsatira zake, titha kunena kuti mitengo yaying'ono ikukula msinkhu, ndi yakale m'lifupi. Njirazi zimadalira mtundu wamitengo ndi chilengedwe.
