Itswele, ijinja, kunye negalikhi zizithako eziyimfuneko ekuphekeni nasekuphekeni kumawakawaka amakhaya. Ukuba kukho imiba yokhuseleko lokutya kunye nezithako ezisetyenziswa yonke imihla, ilizwe lonke liya kuphakuzela ngokwenene. Kutshanje, iisebe lokubeka iliso kwimarikeufumene uhlobo "lwe-chives ezidityanisiweyo" ngexesha lokuhlolwa okungaqhelekanga kwimarike yemifuno eGuizhou. Ezi zitshizi ziyathengiswa, kwaye xa uzihlikihla ngobunono ngezandla zakho, izandla zakho ziya kungcoliswa ngombala oluhlaza okwesibhakabhaka.
Kutheni le nto i-chives yokuqala eluhlaza ijika ibe luhlaza xa ikhuhliwe? Ngokweziphumo zophando ezibhengezwe ngabasemagunyeni bolawulo basekhaya, isizathu sokutshintsha umbala kwechives sisenokuba ngenxa yesibulali-zinambuzane “umxube weBordeaux” otshizwe ngamafama ngexesha lenkqubo yokutyala.
Yintoni "i-Bordeaux liquid"?
Ukudibanisa i-copper sulfate, i-quicklime kunye namanzi kumlinganiselo we-1: 1:100 kuya kwenza "isibhakabhaka esiluhlaza se-colloidal suspension", esiyi "Bordeaux mix"
Isetyenziselwa ntoni "i-Bordeaux liquid"?
Kwi-chives, ulwelo lweBordeaux lusebenza ngokubulala umngundo kwaye “lunokubulala” iintlobo ngeentlobo zeentsholongwane. Emva kokuba umxube weBordeaux utshizwe phezu kwezityalo, uya kwenza ifilimu ekhuselayo enganyibiliki ngokulula xa ibonakaliswe emanzini. Iiyoni zethusi kwifilimu ekhuselayo zinokudlala indima ekuzalweni, izifouthintelo nolondolozo.
Iyingozi kangakanani i-"Bordeaux liquid"?
Izithako eziphambili ze "Bordeaux liquid" ziquka i-lime e-hydrated, i-copper sulfate kunye namanzi. Umthombo oyintloko wemingcipheko yokhuseleko yi-ion zobhedu. I-Copper yintsimbi enzima, kodwa ayinayo ityhefu okanye iqoqo letyhefu. Yenye yezinto ezibalulekileyo zentsimbi kumzimba womntu. Abantu abaqhelekileyo kufuneka basebenzise i-2-3 mg ngosuku.IKomiti yeNgcali kwizongezo zokutya (JECFA)phantsi kwe-WHO ikholelwa ukuba, ukuthatha umntu omdala we-60-kg njengomzekelo, ukuthathwa kwexesha elide lemihla ngemihla ye-30 mg yobhedu akuyi kuba yingozi kwimpilo yabantu. Ke ngoko, "i-Bordeaux liquid" ikwathathwa njengesibulala-zinambuzane esikhuselekileyo.
Yeyiphi imida yolawulo ye "Bordeaux Liquid"?
Ngenxa yokuba ubhedu lukhuselekile ngokwentelekiso, amazwe ehlabathini lonke awakayicacisi ngokucacileyo imida yawo ekutyeni. Imigangatho yelizwe lam yakha yachaza ukuba intsalela yobhedu ekutyeni ayifanele ibe ngaphezu kwe-10 mg/kg, kodwa lo mda warhoxiswa ngo-2010.
Ukuba iimeko zivuma, kucetyiswa ukuba uthenge kwiitshaneli eziqhelekileyo ezinje ngeevenkile ezinkulu kunye neemarike ezinkulu zamafama, zicwilise ngokucokisekileyo ngaphambi kokuba utye ukuze ususe iintsalela zezibulali-zinambuzane ezinyibilikayo emanzini, emva koko uhlambe ngononophelo amagqabi kunye neziqu zetswele kunye nezikhewu ukuze uzisuse ngokufanelekileyo. Iintsalela ze-pesticide ezingenayo amanzi ezifana ne "Bordeaux Liquid" zinokuphucula ngokufanelekileyo ukhuseleko lwe-chives okanye ezinye iziqhamo kunye nemifuno.
