Ehlabathini kukho iindidi ezingaphezu kwewaka. Ukhula luyancintisana nezityalo zezityalo kwisibambano sokukhanya, umswakama kunye nezondlo ezibalulekileyo, ezibangela umonakalo kwimveliso yesityalo. Ngoko ke, kwiindawo apho iifuno nezityalo zikhulile, kubalulekile ukulwa nokhula. Zizo: zonyaka, ezikhulayo zisuka kwimbewu (ininzi) kwaye zingapheliyo, zikwazi ukuvelisa phantsi kweemeko ezithile ngonyaka.
Indlela yokuqala kunye neyona ndlela eyaziwayo yokulawula ukhula - ukusila akuniki ipesenti yokuqinisekisa ukuwagxotha, kuba ukhula olungapheli lunokukhula ngaphandle kweengcambu ezincinci ezisemhlabeni. Ngaphandle koko, ukuhluma kuyinkqubo enzima kakhulu kwaye akubona bonke abalimi abanako. Kodwa ngoku kutshanje, i-herbicide yenzelwe ukunceda ukulwa nokhula, amalungiselelo amakhemikhali asetyenziswe emacaleni amaqabunga kunye neziqu, kwaye ngokukhawuleza athathwe yiyo yonke isityalo.
Ngokuqinisekileyo, ulwalamanzi luyinto entle, kuphela ukufumana umphumo omuhle, kufuneka usebenziswe kakuhle. Kungenxa yoko siqwalasela kwinqaku iinjongo eziphambili kunye nemithetho yokusetyenziswa kwezinto ezinobungozi bokutshabalalisa ukhula.
Uhlobo lwee-herbicide ukusuka kwokhula
Okwangoku, iimveliso ezingama-240 zolawulo lwokhula (i-herbicide) zinikezelwa kubathengi, kwaye uhla lwazo luhlala lushintshana: ekubeni i-high-toxic and non-effective herbicides, efunekayo isetyenziswe kumaxabiso amakhulu, athatyathwa yizilwanyana ezinobungakanani, ezincinci kunye nezisebenzayo kakhulu Ixabiso eliphantsi lokusetyenziswa.
Ukwenziwa kweekhemikhali zonyango kulwahlula:
- engavumelekanga;
- (ubuninzi babo).
Indlela esichaphazela ngayo ukhula yile:
- isenzo esikhethiweyo - ukubhubhisa kuphela amaqela athile kokhula: ukhula, i-lontrel-300 okanye i-lontrel-300D, i-lapis lazuli;
- isenzo esiqhubekayo (jikelele), ukutshabalalisa zonke izityalo: i-sniper, i-fort fortan, i-roundup, i-glyphos, umhlaba, i-rornado, i-reglon, i-arsenal, i-basta.
Kukho izichumisi ezinzima kunye nokudibanisa i-herbicide (dicamba), ezicetyiswayo ukuba zisetyenziswe emanqeni ukusuka kwokhula kunye ne-moss.
Imithetho eyisiseko yokusetyenziswa kweengcambu zokulwa nokhula
Ukuze uphathe ukhula njengoluhlu lwee-herbicides njengolusebenzayo, kufuneka lwenziwa ngokuqwalasela le mithetho elandelayo:
- qwa lasela uhlobo lokhula, isityalo esilinywa, ixesha kunye neqondo eliphezulu lokunyanga;
- Kunokwenzeka ukuba angasebenzisi onke amalungiselelo akhiqiweyo kwiindawo zemiyezo yabantu;
- xa ukhetha utywala, qwabela ingqalelo into esebenzayo, ekubeni amaninzi amalungiselelo kunye neendlela ezifanayo zinamagama ahlukeneyo;
- basebenzise kwisiza somntu siqu, kuphela ngokwemimiselo yokusetyenziswa echazwe kwimigaqo yale nkunkuma;
- Ukucubungula kungenziwa entwasahlobo, ehlobo nasekwindla;
- umphumo omhle kumhlaba kufuneka ube ngumlinganiselo okwaneleyo wobumanzi, kodwa isityalo sesityalo kufuneka singabi manzi emvula okanye ngombethe;
- Kungcono ukucwangcisa xa ukhula lukhula kwaye lukhula ngokukhawuleza;
- Ungasebenzisi iziyobisi xa ubusika busuku buphantsi kwe-6 ° C, kwaye ukushisa komso kuthathwa njengokuba ngaphezu kwe-25 ° C;
- Ungasebenzisi i-herbicides ukuba isityalo sonakaliswe kakhulu;
- Ungasebenzisi i-herbicide efanayo, kusebenza ngokubanzi ukusebenzisa umjikelezo we-herbicide (ukuchithwa kwe-herbicides);
- Sebenzisa kuphela amanzi ahlambulukileyo ekukhuliseni i-herbicide.
Ngenxa yokuba ulwaphulo olunokutshabalalisa lunokutshabalalisa bonke ukhula okanye izityalo ezithile, zingasetyenziselwa ukutshatyalaliswa ngokupheleleyo kokhula, kodwa kunye nokucoca utshani kunye nokucoca izityalo emva kokuvela, ngaphandle kokulimaza izityalo zezityalo. Kodwa kusekhona izinto ezinetyhefu, ngoko ke xa uphatha ukhula kunye ne-herbicides, zihambelane nemilinganiselo yokukhusela.
