Igihe gikwiye cyo gukoresha ibyatsi ni nyuma ya saa kumi n'ebyiri z'umugoroba.Bitewe n'ubushyuhe buke n'ubushyuhe bwinshi muri iki gihe, amazi azaguma ku mababi y'ibyatsi igihe kirekire, kandi urumamfu rushobora gukuramo neza ibyatsi.Nibyiza kunoza ingaruka zo guca nyakatsi, kandi mugihe kimwe, umutekano wibiti by ibigori urashobora kunozwa, kandi phytotoxicity ntabwo byoroshye kubaho.

Ni ryari gushira ibyatsi nyuma yingemwe zi bigori?

1. Kuberako ibyatsi biva nyuma yo kuvuka byatewe, bifata amasaha 2-6 kugirango inzira yo kwinjizwa.Muri aya masaha 2-6, niba ingaruka ziterwa na herbicide ari byiza muri rusange bifitanye isano rya hafi nubushyuhe nubushuhe bwikirere.Sasa mugitondo, cyangwa saa sita na nyuma ya saa sita igihe ikirere cyumye.

2. Bitewe n'ubushyuhe bwinshi, urumuri rukomeye, hamwe no guhindagurika vuba kwa miti y’amazi, imiti y’amazi izashira nyuma gato yo gutera, ku buryo ingano y’ibyatsi byinjira muri nyakatsi iba mike, ibyo bikaba byaviramo kwangirika bidahagije, bityo bikagira ingaruka kuri ingaruka zibyatsi.Iyo utera mugihe cy'ubushyuhe bwinshi n'amapfa, ingemwe z'ibigori nazo zikunda kwibasira phytotoxicity.

3. Igihe gikwiye cyo gutera ni nyuma ya saa kumi n'ebyiri z'umugoroba, kubera ko muri iki gihe, ubushyuhe buri hasi, ubuhehere buri hejuru, amazi aguma ku bibabi by'ibyatsi igihe kirekire, kandi urumamfu rushobora kwinjirira neza. ibimera., bifasha kwemeza ingaruka zo guca nyakatsi, kandi imiti nimugoroba irashobora kandi guteza imbere umutekano w ingemwe zi bigori, kandi ntabwo byoroshye gutera phytotoxicity.

4. Kubera ko ibyinshi mu byatsi bivamo nyuma yibigaragara mu bigori ari nicosulfuron-methyl, ubwoko bumwebumwe bwibigori bwumva iki gice kandi bukunze kwibasirwa na phytotoxicity, bityo ntibukwiriye guhingwa ibigori bitera ibigori byiza, ibigori byashashara, urukurikirane rwa Denghai nibindi amoko agomba guterwa, kugirango yirinde phytotoxicity, kubwoko bushya bwibigori, birakenewe kwipimisha hanyuma bigatezwa imbere.

Nigute ushobora gukoresha ibyatsi nyuma yo kugaragara mubigori?

1. Reba ubunini bw'ibyatsi

.

(2) Kubera ko ibyatsi ari bito cyane, nta gace k’imiti, kandi ingaruka zo guca nyakatsi ntabwo ari nziza.Ibyatsi byiza byimyaka ni amababi 2 numutima 1 kugeza amababi 4 numutima 1.Muri iki gihe, urumamfu rufite ahantu runaka rusaba.Kurwanya nyakatsi ntabwo ari binini, bityo ingaruka zo guca nyakatsi ni nziza.

2. Ubwoko bwibigori

Kubera ko ibyatsi byinshi nyuma y’ibigaragara mu bigori ari nicosulfuron-methyl, ubwoko bumwebumwe bwibigori bwumva iki gice kandi bukunze kwibasirwa na phytotoxicity, bityo ntibishoboka gutera imirima y ibigori aho ibigori biryoshye, ibigori bishashara, urukurikirane rwa Denghai nubundi bwoko.Kugirango habeho phytotoxicity, ubwoko bushya bwibigori bugomba kugeragezwa mbere yo kuzamurwa.

3. Ikibazo cyo kuvanga imiti yica udukoko

Imiti yica udukoko twa Organophosifore ntigomba guterwa iminsi 7 mbere na nyuma yo gutera ingemwe, bitabaye ibyo biroroshye gutera phytotoxicity, ariko irashobora kuvangwa nudukoko twa pyrethide.Umuti wuzuye umutima.

4. Kurwanya nyakatsi ubwayo

Mu myaka yashize, ubushobozi bwibyatsi byo kurwanya imihangayiko bwarushijeho kuba bwiza.Kugirango wirinde guhumeka gukabije kwamazi mumubiri, urumamfu ntirukomera cyane kandi rukomeye, ahubwo rukura imvi kandi rugufi, kandi imyaka nyakatsi ntabwo ari nto.Ibyatsi bibi ahanini bitwikiriwe nibintu bito byera umubiri wose kugirango bigabanye amazi.
