Ngenxa yokuvutha okungekuhle kanye nokuwohloka okusheshayo kwe-rimsulfuron emhlabathini, ngeke kuthinte amanzi aphansi komhlaba kanye nezilimo ezilandelayo emthanjeni onconyiwe, okubuye kube nomehluko omkhulu phakathi kwale ngxenye futhiHamosulfuron-methyl.
Ngokuyinhloko esetshenziselwa ukhula lwensimu yama-corn, amazambane, i-konjac, ugwayi, upelepele, amazambane amnandi, nemithi ethile yendabuko yaseChina.
Akugcini nje kuphela futhi kulawule futhi kulawule iCeperus Rotundus, kepha kuphumelela futhi ngokulwa nokhula lonyaka nokhula olubanzi njenge-ryegrass ebanzi, izithombo ze-horseem, i-abutilon, i-abutilon, iron amaranth , isikhwama se-purslane, isikhwama sikamalusi, nedada kuphela.
Ukhula olungenhla lunemiphumela emihle yokulawula ezigabeni zazo zokuqala, kepha imiphumela yazo ayimpofu ezigabeni zawo ezindala futhi ithambekele ekutholeni kabusha.
Indlela yokhula yeRimsulfuron ukuthi izithako ezisebenzayo zidonswa iziqu, amaqabunga, nezimpande zokhula, futhi zidluliselwa ngaphakathi komzimba we-amino acid kukhula, ukuvimbela ukwahlukaniswa kwamaseli, nokuthola umphumela wokuqedwa kweseli .
Ukuphendula okunobuthi kungabonakala kukhula olubucayi kungakapheli izinsuku ezintathu, kepha kuthatha isikhathi eside ukufinyelela utshani obufile. Isibonelo, kuvame ukuthatha izinsuku ezingaphezu kuka-20 ze-aconite ukuze zife ngokuphelele ubuthi. Lapho umswakama wenhlabathi uphansi, isikhathi sotshani esifile sidinga ukunwetshwa ngezinsuku ezingaphezu kuka-30.
Ukusetshenziswa kwe-rimsulfuron ezitshalweni ezahlukahlukene
① amasimu ommbila
Ukusetshenziswa kwe-rimsulfuron emkhakheni we-corn kufanele kwenziwe esigabeni seqabunga esingu-3-5 sommbila, 2-4 esiteji seqabunga sokhula oluhle lwe-gramine Ngemuva kokuthi ukhula luphelele, i-5-7g ye-25% rimsulfuron kufanele isetshenziswe ku-Mu. Ngemuva kwe-dilution yesibili (kunesidingo), ama-30kg wamanzi kufanele angezelwe ukuze ahlolwe ngokuqondile.
② Amasimu weChili
Lapho usebenzisa i-Rimsulfuron emasimini eChili, kufanele isetshenziswe ngemuva kwesiteji sokutshala okuhamba kancane kweChili Pepper Transplantation, futhi exutshwe ne-quizalofop-P-ethyl noma i-clethodim esigabeni seqabunga esingu-3-5 sokhula. Kungathuthukisa amandla okuqeda ukhula notshani futhi kunemiphumela emihle yokulawula kukhula olujwayelekile lwe-Broadleaf emasimini aseChili njenge-aconitum, amaranthus, kanye nePortulaca.
Qaphela: Lapho usebenzisa i-rimsulfuron emasimini wepelepele, isifutho esiqondisa kufanele samukelwe.
③ Izinkundla zamazambane
Ngokuthumela ukhula olukhula lwe-potato, isifutho esiqondisa phakathi kwemigqomo kuyadingeka futhi. Isigaba seqabunga 2-5 sokhula isikhathi esihle kakhulu sokulawula. Ngaphansi komthamo onconyiwe ku-Mu, kunconywa ukuxuba ne-quizalofop-P-ethyl noma i-clethodim. Lapho ukhula lobuningi buphakeme, ama-surfactants angangezwa ndawonye.
