Isityalo ngasinye sifuna ukudala imimiselo engcono kwimithi ekhula kwisiqephu sakhe. Kwaye kunjalo, kukho iimeko xa umnini unombuzo: ungayinisela njani umthi ukuze ufike ngokukhawuleza? Kweminye, le ndlela ibonakala ingahambelani, kodwa ngamanye amaxesha akukho ndlela enye ngaphandle.
Ngokomzekelo, kwenzeka ukuba umthi usele udala, isiqu sakhe singaphezu kwama-30 cm ububanzi, kodwa akunakwenzeka ukuba usike kwaye usilahle, kuba kukho izakhiwo kwindawo esondeleyo okanye zonke izithuba ezijikeleze zihlala kwezinye izityalo. Kwaye kukho into eyodwa kuphela - ukuyomisa umthi ngeekhemikhali.
Ukusetyenziswa kweekhemikhali ukutshabalalisa umthi
Ukuba uthatha isigqibo sokubhenela kwiikhemikhali ukuze umise umthi, ngoko kufuneka ukhethe ithuluzi elifanelekileyo le nto. Ngokuqhelekileyo, izinto zephemikhali zithintela kwinkqubo yesityalo. Ngaphambi kokuthulula ingcambu yomthi ukuba uyomise, kuyimfuneko ukwazi ukubunjwa komhlaba phantsi kwayo. Ngamanye amaxesha, endaweni yeengcambu, zichazwe kwiikhemikhali kwinqaba lomthi okanye izicubu zalo eziphilayo.
Ukuba kukho elo thuba, unganqumla umthi womthi, uze usebenzise iikhemikhali ukutshabalalisa isiqu. Ngoko unokukrazula umthi ongafunekiyo kwisayithi yakho ngokukhawuleza. Makhe sibone ukuba yeyiphi indlela yeekhemikhali engasetyenziselwa ukuma umthi:
- I-nitrate ye-sodium isetyenziswe ngokuqhelekileyo ukutshiza. Nangona kunjalo, ngamanye amaxesha kuya kuziswa ngqo kumhlaba okanye kwisihlahla somthi. Isiphumo esheshayo sinokufumaneka xa ufaka i-nitrate kwisihlahla esingenawo umthi: ngomnyaka umthi uya kumile kwaye usenokutshiswa. Ukunisela umhlaba kuya kusebenza kuphela emva kweminyaka embalwa.
- I-ammonium nitrate ifana nesiphumo sayo kwesodium, kodwa ikwahluke. Iitrate enjalo esekelwe kwi-urea ikhawuleza inkqubo yokwehliswa kweenkuni, kwaye ke iingcambu zomthi zibe yichumbo. Kule meko, i-trunk eneempawu ezikhulayo zokumisa zingasuswa, kwaye iingcambu zavulwa kwakhona ngesisombululo se-nitmonium nitrate.
- Ulwalamano oluthi "Roundup" okanye "i-Tornado" lisoloko lisetyenziselwa ukutshabalalisa imithi engafunekiyo. Faka isicelo sale mali kwi-deconstruction of low value value plants, kwaye ukuba kuyimfuneko, susa i-stand in the plant. Amalungiselelo "Arsenal" kunye ne "Arbonal" anekhono eliphezulu lokungena kwimithi, asetyenziselwa ukunqumla amaphecana amakhulu ehlathi, nakwiindawo zokulima kunye nezinye izityalo zokulima.
- "I-Pikloram" isebenza ngokufanelekileyo ekutheni amanzi aphuze umhlaba, kwaye xa ahlamba umthi ngokwawo. Esi sidakamizwa senza ingcinezelo kwinkqubo yenkcaso, ekhokelela ekumiseni isityalo sonke.
