Ni ryari ingano ari nziza mu guca nyakatsi?90% by'abahinzi ntibazi kugenzura ingano za Jijie

Ikibazo cyo kumenya niba gukoresha imiti yica ibyatsi (cyane cyane nyuma yo kuvuka, nibi bikurikira byose byerekana ibyatsi biva mu bimera) bizahinduka impaka buri mwaka.No mukarere kamwe, hazaba amajwi atandukanye.Bamwe mu bahinzi batekereza ko ingaruka zica ibyatsi mu mwaka ushize ari nziza, impamvu nyamukuru ni uko kurwanya nyakatsi mbere y’umwaka ari muke;ikindi gice cyabahinzi batekereza ko ingaruka zibyatsi nyuma yumwaka ari nziza, impamvu nyamukuru nuko igenzura ryuzuye, ninde ufite ukuri ninde wibeshye, iyi ngingo ikubiyemo, nzaguha isesengura rirambuye.
Reka mbanze ntange igisubizo cyanjye: ibyatsi birashobora gukoreshwa haba mbere na nyuma yumwaka, ariko birasabwa ko abantu bose babikoresha mbere yumwaka.
Kugeza ubu, bitewe n’ikirere gitandukanye, ubushyuhe n’ibindi bihe mu turere twahinzweho ingano, hari kandi itandukaniro mu gihe cyo gufata imiti.Mubyukuri, imiti irashobora gukoreshwa uko umwaka utashye.
Ariko, ukurikije imikurire y'ingano n'ibyatsi, icyifuzo rusange ni ukuba mwiza mbere.
Impamvu ni:
Ubwa mbere, urumamfu rwagaragaye mu myaka mike ishize, kandi kurwanya imiti yica ibyatsi ntabwo ari binini cyane.
Icya kabiri, birasobanutse neza.Nyuma yumwaka, nyuma yo gufunga ingano zingano, urumamfu ntirukwiye kwibasirwa n ibyatsi, bizagira ingaruka kumyatsi.
Icya gatatu, ibyatsi bimwe na bimwe bigira ingaruka ku ngano.Nyuma ya spray hashyizweho, umusaruro wingano uzagira ingaruka.

Impamvu zo kwemeza ibyatsi
1. Ingaruka zo guca nyakatsi
Mubihe bimwe, ingaruka zo gukoresha imiti yica ibyatsi mbere yumwaka ni nziza kuruta iyo nyuma yumwaka.Hariho impamvu eshatu zingenzi.Imwe ni uko kurwanya nyakatsi ari bito;Imyaka itatu irashize, mbere yuko ingano zifungwa, amazi y’ibyatsi yashoboraga guterwa hejuru y’urumamfu, ariko ingano zimaze gufungwa, umubare w’ibyatsi wagabanuka.Bavuga ko ingaruka zo guca nyakatsi umwaka ushize ziruta iz'umwaka nyuma (ibintu bimeze hanze).
2. Igiciro cyo guca nyakatsi
Duhereye ku isesengura ry'igiciro cyo guca nyakatsi, umubare w'ibyatsi biva mu mwaka ushize ni bike ugereranije n'umwaka ushize.Amabwiriza yo gukoresha azasanga akoreshwa mugihe urumamfu ruri murwego rwibibabi 2-4, ni ukuvuga ko dosiye ari dosiye ya nyakatsi nyuma gato yuko havutse ibyatsi (mumyaka yashize), na nyuma yumwaka mushya , urumamfu rugeze ku mababi 5-6., cyangwa binini, niba ushaka kugera ku ngaruka zo guca nyakatsi, uzongera dosiye ukurikije.Urutonde rwimiti yibasiye mu butaka mbere yumwaka, n amanota 7-8 gusa nyuma yumwaka, ibyo bikaba byongera ikiguzi cyimiti.
3. Ibibazo byumutekano
Umutekano uvugwa hano ahanini ni umutekano w'ingano.Abantu bose birashoboka ko bazi ko ingano nini, niko bishoboka cyane kuba phytotoxicité nyuma yo gutera imiti yica ibyatsi (bivuze ko), kandi nyuma yo gufatanya, ntidushobora gukoresha imiti yica ibyatsi., Nabonye abahinzi bamwe, kugirango bategereze ibihe byiza nyuma yumwaka, ingano zahujwe kandi baracyakoresha ibyatsi.Birashoboka ko ibisubizo byo gutegereza ari uko ingano zifite phytotoxicity.Mugihe ukoresheje ibyatsi (2-4 byamababi yicyatsi) mumyaka mike ishize, phytotoxicity nayo izabaho (ubushyuhe butari bwo, uburyo bwo gukora, nibindi mugihe cyo kuyikoresha), ariko amahirwe aragabanuka cyane.
4. Ingaruka z'igihingwa gikurikira
Bimwe mu byatsi biva mu byatsi bizatera phytotoxicity (ibibazo by’ibisigisigi bya herbicide) mu bihingwa ku giti cye mu gihingwa gikurikiraho, nk’ingaruka za Trisulfuron ku mbuto.Ntabwo byemewe gutera ibishyimbo, kuko bishoboka cyane ko bitera phytotoxicity, kandi imiti imwe yica ibyatsi hamwe na Trisulfuron-methyl, iyo ikoreshejwe umwaka ushize, bizagabanya cyane ingaruka ku bihingwa byakurikiyeho, cyangwa bitabaho, kandi hariho an inyongera 1- amezi 2 kugirango ibyatsi byangirika.
Nyuma yo kuvuga impamvu wahisemo gukoresha ibyatsi byica ingano umwaka ushize, reka tuvuge kubyitonderwa mugihe ukoresha ibyatsi byica ingano (byaba mbere cyangwa nyuma yumwaka)

Icya kane, gukoresha imiti yica ibyatsi
1. Iyo utera ibyatsi, ubushyuhe ntibukwiye kuba hasi cyane, kandi urebe ko ubushyuhe mugihe cyo gutera buri hejuru ya dogere 10 (itandukaniro ryubushyuhe ni rinini, kandi ubushyuhe mugitondo burashobora gukoreshwa).
2. Iyo utera ibyatsi, birasabwa guhitamo ikirere cyizuba.Nyuma ya saa kumi za mugitondo na mbere ya 16h00 nyuma ya saa sita, ntukayikoreshe mugihe cyumuyaga.
3. Mugihe utera ingano zica ibyatsi, vanga amazi neza, ntukongere gutera cyangwa kubura spray.
Mu myaka yashize, kuba ingano zo mu gasozi zarushijeho gukomera, kandi ingano zo mu gasozi dukunze kuvuga mu byukuri zigabanijwemo brome, oat yo mu gasozi, hamwe nimbuto.Kubera ko akenshi tudashobora kumenya ubwoko bw'ingano zo mu gasozi, imiti iribeshya, ku buryo hariho ingano nyinshi kandi nyinshi zo mu gasozi, zigira ingaruka ku musaruro w'ingano.
Birakwiye gukubita umurima w'ingano ingano zo mu gasozi?Nizera ko abahinzi n’abakoresha ahantu henshi bahangayikishijwe niki kibazo, kandi muri uyu mwaka, ingano nyinshi zo mu gasozi mu murima w’ingano kuruta mu myaka yashize.Byongeye kandi, ingano zo mu gasozi ntabwo byoroshye kugenzura, kandi abahinzi bafite impungenge ko bizagira ingaruka ku musaruro w'ingano umwaka utaha.
