Kunini lapho ukolweni okulungele ukuhlakula?Abalimi abangu-90% abazi ukuthi bangawulawula kanjani ukolweni weJijie

Umbuzo wokuthi kufanele kusetshenziswe imithi yokubulala ukhula kakolweni (ikakhulukazi ngemva kokuhluma, futhi konke okulandelayo kumelela imichiza yokubulala ukhula ngemva kokuhluma) izoba yimpikiswano minyaka yonke.Ngisho nasendaweni eyodwa, kuzoba namaphimbo ahlukene.Abanye abalimi bacabanga ukuthi umphumela wama-herbicides onyakeni odlule muhle, isizathu esikhulu ukuthi ukumelana nokhula ngaphambi konyaka kuphansi;enye ingxenye yabalimi bacabanga ukuthi umphumela we-herbicides ngemva konyaka muhle, isizathu esiyinhloko ukuthi ukulawula kuqedile, okulungile nokuthi ubani ongalungile, lesi sihloko okuqukethwe , ngizokunikeza ukuhlaziywa okuningiliziwe.
Ake nginikeze impendulo yami kuqala: imithi yokubulala ukhula ingasetshenziswa ngaphambi nangemuva konyaka, kodwa kuyanconywa ukuthi wonke umuntu ayisebenzise ngaphambi konyaka.
Njengamanje, ngenxa yesimo sezulu esihlukile, izinga lokushisa kanye nezinye izimo ezindaweni zokutshala ukolweni ebusika, kukhona futhi umehluko ngesikhathi somuthi.Eqinisweni, imithi ingasetshenziswa unyaka nonyaka.
Kodwa-ke, ngokusho kokukhula kukakolweni nokhula, isincomo esijwayelekile kufanele sibe ngcono ngaphambili.
Isizathu siwukuthi:
Okokuqala, ukhula olusanda kuvela eminyakeni embalwa edlule, futhi ukumelana nemithi yokubulala ukhula akukukhulu kakhulu.
Okwesibili, icophelela kakhulu.Ngemva konyaka, ngemva kokuvalwa kweqolo likakolweni, ukhula akufanele lushaywe yi-herbicide, okuzothinta umphumela wokukhipha ukhula.
Okwesithathu, eminye imithi yokubulala ukhula inemiphumela ethile engemihle kukolweni.Ngokuhamba kwesikhathi isifutho sisetshenziswa, isivuno sikakolweni sakamuva sizothinteka.

Izizathu zokuncoma ama-herbicides
1. Umphumela wokukhula
Ngaphansi kwezimo ezifanayo, umphumela wokusebenzisa ama-herbicides ngaphambi konyaka ungcono kakhulu kunalowo wangemva konyaka.Kunezizathu ezintathu eziyinhloko.Enye ukuthi ukumelana nokhula kuncane;Eminyakeni emithathu edlule, ngaphambi kokuba ukolo uvalwe, uketshezi lwe-herbicide lwalungase lufuthwe ngokuqondile ebusweni bokhula, kodwa ngemva kokuba ukolweni uvaliwe, inani lokhula lalizoncipha.Kuthiwa umphumela wokukhipha ukhula wangonyaka odlule ungcono kunalowo wangonyaka olandelayo (izimo ezifanayo zangaphandle).
2. Izindleko zokukhula
Kusukela ekuhlaziyweni kwezindleko zokuhlakula, inani lemithi yokubulala ukhula ngonyaka odlule lingaphansi kwalelo ngonyaka odlule.Imiyalo yokusetshenziswa izothola ukuthi isetshenziswa lapho ukhula lusesigabeni seqabunga le-2-4, okungukuthi, umthamo umthamo wokhula ngemuva nje kokuvela kokhula (eminyakeni edlule), nangemva konyaka omusha. , ukhula lufinyelele amaqabunga angu-5-6., noma ngisho nakakhulu, uma ufuna ukufeza umphumela wokukhipha ukhula, uzokwandisa umthamo ngokufanele.Iqoqo lemithi lishaya i-mu eyodwa yomhlaba ngaphambi konyaka, futhi amaphuzu angu-7-8 kuphela ngemva konyaka, okwandisa ngokungabonakali izindleko zemithi.
3. Izinkinga zokuphepha
Ukuphepha okukhulunywa ngakho lapha ngokuyinhloko ukuphepha kukakolweni.Cishe wonke umuntu uyazi ukuthi lapho ukolweni umkhulu, ayanda amathuba okuba ne-phytotoxicity ngemva kokufafaza ama-herbicides (uma sikhuluma ngokuqhathanisa), futhi ngemva kokuhlanganisa, ngeke sisakwazi ukusebenzisa imithi yokubulala ukhula., ngibone abalimi, ukuze balinde isimo sezulu esilungile emva konyaka, ukolo uhlanganisiwe futhi basafaka imithi yokubulala ukhula.Kucatshangwa ukuthi umphumela wokulinda ukuthi ukolweni une-phytotoxicity.Ngenkathi usebenzisa ama-herbicides (isigaba seqabunga le-2-4 sokhula) eminyakeni embalwa edlule, i-phytotoxicity nayo izokwenzeka (izinga lokushisa elingalungile, indlela yokusebenza, njll. ngesikhathi sokusetshenziswa), kodwa amathuba ayancipha kakhulu.
4. Umthelela wesivuno esilandelayo
Ezinye izithako zokubulala ukhula zikakolweni zizodala i-phytotoxicity (izinkinga zensalela ye-herbicide) esitshalweni ngasinye esitshalweni esilandelayo, njengomphumela we-Trisulfuron kumantongomane.Akunconywa ukutshala amantongomane, njengoba kungenzeka kakhulu kubangele i-phytotoxicity, futhi umuthi ofanayo wokubulala ukhula nge-Trisulfuron-methyl, uma usetshenziswe ngonyaka odlule, uzowunciphisa kakhulu umthelela ezitshalweni ezilandelayo, noma ungenzeki, futhi kukhona izinyanga ezi-1-2 ezengeziwe ukuze umuthi wokubola ubole.
Ngemva kokukhuluma ngokuthi kungani wakhetha ukusebenzisa izibulala-khula zikakolweni ngonyaka odlule, ake sikhulume ngezinyathelo ezithile zokuphepha lapho usebenzisa izibulala-khula zikakolweni (noma ngabe ngaphambi noma ngemva konyaka)

Okwesine, ukusetshenziswa kokhula kakolweni izinyathelo zokuphepha
1. Uma ufutha ama-herbicides, izinga lokushisa akufanele libe phansi kakhulu, futhi uqinisekise ukuthi izinga lokushisa ngesikhathi sokufafaza lingaphezu kwama-degrees angu-10 (umehluko wokushisa mkhulu, futhi izinga lokushisa ekuseni emini lingasetshenziswa).
2. Uma ufutha ama-herbicides, kutuswa ukuba ukhethe isimo sezulu esinelanga.Ngemva kuka-10:00 emini nangaphambi kuka-16:00 ntambama, ungayisebenzisi esimweni sezulu esinomoya.
3. Uma ufutha isibulala-khula sikakolweni, xuba uketshezi ngokulinganayo, ungaphinde ufafaze noma ugeje isifutho.
Eminyakeni yamuva, ukuvela kukakolweni wasendle kuye kwaba kubi nakakhulu, futhi ukolweni wasendle esivame ukusho ukuthi empeleni uhlukaniswe i-brome, i-oat yasendle, kanye ne-buckwheat.Ngenxa yokuthi ngokuvamile asikwazi ukusho ukuthi hlobo luni lukakolweni wasendle, umuthi awulungile, ukuze ukwanda kukakolweni wasendle, okuthinta isivuno sikakolweni.
Ingabe kufanelekile ukushaya ukolweni wasendle ensimini kakolweni manje?Ngikholelwa ukuthi abalimi nabasebenzisi ezindaweni eziningi bakhathazekile ngale nkinga, futhi kulo nyaka, kunokolweni wasendle omningi emasimini kakolweni kunaseminyakeni edlule.Ngaphezu kwalokho, ukolweni wasendle akulula ukuwulawula, futhi abalimi bakhathazekile ngokuthi kuzophazamisa ukukhiqizwa kukakolweni ngonyaka ozayo.
