Fengdan (Izina rya siyansi: Paeonia ostii 'Feng Dan Bai')
I. Ubuyobozi bw'Ikigo c'Ivyatsi vy'Ivya Fengdan
Guhinga imbuto
Imbuto zitangura kumera imisi 20–30 inyuma yo kubiba, kandi imizi mito ishobora gushika kuri cm 10–20 imbere y’urushana. Mu gihe c’imbeho, igitanda c’imbuto gishobora gupfukwa n’ivyatsi kugira ngo kibe gikingira. Ico gipfukisho gikwiye gukurwamwo muri Ruhuhuma umwaka ukurikira. Intete zizomera hagati -kugeza-mu mpera za Ruhuhuma, kandi ingero zo gutera igitutu ni ngirakamaro.
Iyo ubushuhe bwo mu mpera z’umwaka bushitse kuri degre 18–25 , ingemwe zica zija mu kiringo co gukura vyihuta. Hakwiye kwitwararika kwirinda indwara ziterwa n’ibiherere ku mubiri. Ifumbire y’amababi n’ivyo gutuma amababi akura birashobora gukoreshwa, incuro zitatu hagati ya Werurwe na Ndamukiza.
Gucungera icatsi kibi
Inyuma yo kubiba, ni vyiza gutera acetochlor mw’ivu imbere y’uko ivyatsi bibi bimera. Mu kiringo co gukura, gufungura ubutaka ku gihe no gukura ivyatsi bibi kugira ngo ntihagire ivyatsi bibi bitera.
II. Gutera imbuto z'igiti citwa Fengdan
Igihe co gutera
Muri rusangi, ingemwe z’imyaka 2–3-zikoreshwa mu gutera mu mpera z’umwaka, ariko kandi zishobora guterwa mu mpera z’umwaka uko bikenewe.
Gutanga urutonde rw'imbuto
Intete zikwiye gushirwa mu migwi hakurikijwe imyaka n’ingene zikura kugira ngo intete zatewe zikure kimwe.
Uburinzi bw'imbuto
Inyuma yo gutera ivyatsi, ingemwe zikwiye gushirwa mu mifuko zigatwarwa vuba. Intete zidashobora guterwa ubwo nyene zikwiye gupfukwa n’igitutu, canke zigakingirwa n’ububiko bw’umusenyi canke gupfukwa n’ubutaka.
III. Gutegura ubutaka bw'amavuta-Ivyara Fengdan Peony
Guhitamwo urubuga
Ivu ry'umusenyi ry'imbere, ry'agaciro, ry'amazi ni ryiza, rifise pH ya 5.5–8.0. Irinde ubutaka buremereye bw’ibumba n’ahantu hari amateka y’ugukomeza gutera.
Gucungera icatsi kibi
Gukingira icatsi kibi bikwiye gukorwa mu ci no mu mpera z’umwaka imbere yo gutera. Ivyo bishobora gushikako mu guhinga cane kugira ngo imbuto zihambe, mu guhinga mu gitutu kugira ngo zimere kandi zice icatsi kibi, canke mu gukoresha imiti yica icatsi kibi nk’iyitwa glyphosate.
Guhinga cane no gutera ifumbire
Nk’ukwezi kumwe imbere y’uko utera, guhinga ubutaka bushika kure cane gushika ku burebure bwa cm 30–50 hanyuma ubushire ku muco w’izuba. Mu gihe co gutegura ubutaka, ushireko ibiro 800–1500 vy’ifumbire y’iriba-iboze, ibiro 40–50 vy’ifumbire y’uruvange, n’imiti y’udukoko n’ibikoko y’ubutaka ibereye ku mu (hafi hegitari 0,067). Gutegura ubutaka no gutegura igitanda
Imbere yo gutera, ubutaka bukwiye kurimwa bukeyi kandi bukaringanizwa, bugaca bugira ibitanda vy’amabuye vy’agaciro. Ivyo bitanda bikwiye kuba bifise ubwaguke bwa metero 2–3, hakaba hariho inzira n’imigende y’amazi y’amazi bifise uburebure bwa santimetero nka 50 n’ubwaguke.
Iyi ngingo ngenderwako ivuga ku ntambwe nyamukuru z’uguhinga amavuta y’ibiti vy’amavuta, kuva ku gukwiragiza ingemwe no ku gucungera amatongo gushika ku gutegura ubutaka imbere yo gutera, kandi itangwa nk’inzira y’uburimyi buhuye.
