Gukata amabambu no gucyeza igihe — Ukusanura amabambu mu Bujambura

Muri Bangaladeshi, haba bamboo icyiciro gikunze 33. Icyiciro kitatu cyingenzi cyinzira y'imiterere n'ibikorwa bya mbere. Bamboo nini (Bambusa balcooa) — ryiyumvire, ryiyumvire, urwibutso rwamaguru, diameter 8-15 cm, ubuhagarike 15-25 mita, ikoreshwa cyane muri mirimo y'imiterere. Bamboo ya Muli (Melocanna baccifera) — yihuse, ipikinike, diameter 3-7 cm, ubuhagarike 10-20 mita, akabandi k'ibikoresho bya mpeshyi n'imyanda ibukozwe neza, igera cyane mu Chittagong y'umusozi. Bamboo ya Mitinga (Bambusa tulda) — ubunini bwamakungu, diameter 5-10 cm, ikoreshwa muri ingenzi y'umupapiro n'imiterere yepfo.

Bambu murigihe ihita mu myaka 3-5. Bambu ifite imyaka 3-4 ni iyo ifatiye cyane mu nzira y'ubwubatsi — niba umubabuza mbere y'igihe, bambu ni impimbyi kandi irahurwa n'inzira. Inzira z' kumenyera bambu itibyijeye: ibara rijya rimu green ijimye kugeza green-yellow, umukara uri hejuru y'aminya ukarera powder yera (lichen), iyo ukariera hamwe n'isuku ushira ko ari inzira, kandi iyo ukatoka hamwe n'ikumwe ry'umwete wari gutanguruka igisomeko kiri n'igiciro cy'umetal (bambu itakijeye igisomeko gitahambagirwa). Bambu ifite imyaka itangira ku 5 itahita.

Igihe cyiza cyo gukata bambú ni mu gihe cyumwuka — Ugushyingo kugeza Gashyantare. Mu gihe icyo, ubwoko bwa starch no sukari mumurima wa bambú buri mu rwego rwaphanzi, kandi ibi bigabanya ingeso ya sezerani (cyane cyane powder post beetles). Bambú ikarikwa mu gihe cy'imvura (Kamena-Nzeri) ifite starch nyinshi kandi sezerani ibihasira vuba. Gukata igihe hejuru ya muezi mushya nyuma y'igihe cy'ukwezi uzuzuye bigabanya amazi mu bambú — izi ni imamuko y'inyandiko zishyigikiwe n'ubushakashatsi. Tangira gukata mu gitondo ryo kumaze igihe cy'ijoro mugihe ubushyuhe buri bwiyunge.

Umutwe mwiza wa daa (inzira y'ibigeni bya Bangladeshi) ni inzira nyambi yo gukata bamboo. Umutwe wa daa ugomba kuba 30-45 cm kinini kandi uzito upya ngo bamboo ikakatwa mu gihe cyimwe cyangwa kabiri. Gusiga umutwe wa daa ku mahoro mbere yo gukata. Ikipfo cy'imikono nayo kirashobora gukoreshwa mu bamboo nzito. Kubwengeri, wambara ibigeni by'inzira kandi isapato rikomeye — impande z'ibigeni bikaatwe bamboo ni nzira nyayo cyane.

Ntibigomba gukata hejuru ya 30% y'amayinja mu ntera y'ibamboo — ibi bikomeza amahoro n'ubushobozi bwo kugaruka. Mu ntera y'ibamboo ifite umutwe mwiza, 3-8 mayinja amakuru ashobora kuvanwa mu mwaka umwe. Ubwa mbere gukuramo mayinja ashonje, atakubise, n'ayakoshe. Hanyuma hitamo mayinja amakuru akora igihe cyinshi. Tegeka mayinja amashya (amaka 1-2, mahoro na mahoro) n'ibishyimbo bishya.

Kukata amoko n'amapapiro kuva mubambū yacitse. Amoko aratandukanye kuva mu nodi z'ubambū — kukata ibi hafi y'inodi ukoresheje icyuma cy'ubwato. Kukata ubambū kugeza ku burebure bushoboka nk'uko bikenewe — mubisanzwe ibice bya 3-4 mita kingana birahomba kubwanya. Kukata hejuru hejuru y'inodi nka buri kukata, kuko kukata mu rutunguko rw'inodi ushobora gukuba. Shyira amoko n'amapapiro yacitse ku nsi y'itseri ry'ubambū — ibi bihanamura kandi bizaba igitungulu cy'icyamafuro kigizwa mu kiranga gitanga ingufu ku tseri.

Vigeza bamboo yacitse hejuka hejuka — kubyigiza kuri mugongo itangira indwara n'inzira z'inzoka. Ibigeza kuri bamboo cyangwa ibiti bibiri bikora nk'inzira n'amazi agera munsi. Mu Buyangirize, bamboo ikunzweho itwara mu mahoro akwirizwa hamwe n'amazi – ibi byatangira inzira yo kumaza mu mazi. Kutwara kuri landi, koresha imodoka cyangwa icyambi. Inzira yo kumaza ishyikirizwa mu gihe cy'amasaha 24 nyuma y'ugucita bamboo.

Gucura amazi nubwo buryo bwikira kandi bwomeje cyane mu kubungisha ibiti by'umutabdul. Shyira ibiti by'umutuba byose mu mazi ya dam, umurage cyangwa umuyoboro. Niba ibiti by'umutuba bita, byibuza mu mahoro y'amabuye cyangwa inkoni. Bitwike mu mazi mugihe cya viini 4-8 - muri iri gihe mazi aravunda kandi akatera iyeyanire n'amasukali mu ibiti by'umutuba. Iyo iyeyanire yavutse, inzira ntizaza kugira impfu z'ibiti by'umutuba. Ubundi buryo: gutsika mu mahoro y'imbatizo ya borax-boric acid (iramu 50 za borax na 50 za boric acid buri kiliyita y'amazi) bizacura mu viini 2-3 kandi bitanga inzira y'icyakosezo cy'inzira.

Nyuma y'ibyumbu 4-8, kasura bamboo mu mazi hanyuma kugenzura. Ibimenyetso bya bamboo isina sezon: ibara rihinduka kuva icyatsi cy'amajyellow-green kugera ku pale brown, nta sap igikwi ku nkuba z'imbere, nta funka nzuri kuri cut edges. Niba hari sap igikwi cyangwa funka nzuri, kubikira mu mazi mwanya 1-2 w'ibyumbu. Bamboo itasezoniwe neza izirya inzira mu minsi micye y'amezi a kane.

Kubura bambù yatunzwe mu mazina n'uyishyire igaca — kumara mu mahoro y'ijwi rigonacula bambù ikunyagira vuba. Shyiramo bambù neza mu buryo bwasuburanya kumera ku mahali hejuru y'isi nk'uko isi ikorera ku bwose. Kumara mu ijanja mu gihe cy'ibyumbe 4-6. Subiramo bambù rimwe na rimwe mu gihe cyo kumara nk'uko ikumara neza. Menya ko ubwiyunge bwakaje munsi ya 15%. Bambù itarashakuwe ikunyagira kandi ikanagabanywa neza; bambù yatunzwe neza ni yikomeye, yihoshye, kandi itagwomwa n'inzira.

Nigute cyo kumenya niba bamboo yumvise neza: Ubwigize — bamboo yumvitse ni nyinshi itaritse cyane ugereranije na bamboo nshya. Igipimo cyamajwi — mugihe ushakira bamboo yumvitse n'umugote, itanga ijwi ryisubo, riheze; bamboo ishakuze itanga ijwi ritambagirana. Ibara — bamboo yumvitse neza ifite ibara ry'istrawu ry'iyiprofini. Imbaraga y'igice — urubigo rw'imbere ruhumeka kandi rutekaneza, nta kirimba cyangwa fungus. Niba ibimenyetso byamazi bimeze, 12-15% yamazi ni ibihe byiza cyane mu mirimo y'ubwubatsi.

Gabanya bamboo iparففdried mu nzira eshatu. Icyiciro cya mbere — itonje, idacyubwire, imipimo yibice iyo ari yayo, nta nzira z'inzira — igikwi cyo mu nzu n'uku gukora ifurniture, yitanga inzira y'amafaranga menshi. Icyiciro cya kabiri — icyiciro cyemewe cyerekeye kuva cyiciro cyambere cyangwa gifite mica minini — igikwi cyo mu miryango, scaffolding, inzira, nibindi. Icyiciro cya gatatu — imipango, igacyubwire cyangwa gifite inzira z'inzira — irashobora gukoreshwa nk'ibiyobyibyiza cyangwa cyo gukora ibitambitse. Komeza bamboo y'icyiciro kimwe nkimwe.

Bamboo ifitwe neza kandi ikaanze irakagira mu myaka myinshi iyo ihagaze neza. Polepole kubika bamboo mu mahoro — hejuru y'amapiga cyangwa inkuba. Kubika bamboo munsi y'inzu kugira ngo ikinire ku mvua n'izuba ruziga. Kugira ubwenge bw'umuyaga ubarizwa bamboo — urwibutso rutera mu mahoro. Kubika bamboo mu mahoro, ntakubika akayabo — bamboo yanywanya iyo ihagaze. Igihe n'igihe, kontrola bamboo kugira ngo mubone amashanyalazoo — poteri ndogo nyinshi zerekanisha ibibi bya powelder post beetle. Bamboo ifitwe neza iruriwe iracyakira ibisazi.
