Ehlobo, ukukhula kotshani be-turf kuyabuthaka ngenxa yokucindezeleka kokushisa okuphezulu, kanti utshani besikhathi esipholile bungena enkathini yokulala eshisayo. Ngesikhathi esifanayo, izifo ezahlukahlukene, izinambuzane ezibangela izinambuzane, kanye nokhula zifinyelela isikhathi sazo esiphezulu. Uma kungaphathwa kahle, kungaholela kalula ekufeni noma ekuwohlokeni kwezindawo ezinkulu zotshani be-turf. Ungalugcina kanjani futhi uluphathe kahle utshani bakho ehlobo lonke?
Nisela kahle
Amanzi ayisihluthulelo sokunquma ukukhula kotshani. Nakuba kunemvula eningi ehlobo, imvula ayilingani. Uma kuhambisana nokushisa okuphezulu kanye nokuhwamuka okusheshayo, inhlabathi ithambekele esomeni. Kudingeka ukugcwaliswa kwamanzi ngesikhathi esifanele ukuqinisekisa ukukhula okuvamile kotshani, kodwa isikhathi sokunisela kumele sibambeke. kanye nenani lokunisela ukuze kugwenyweizifo zotshaniokubangelwa ukunisela ngokweqile.
1. Isikhathi sokunisela
Ihlobo liyashisa futhi linomswakama, futhi izifo zivamile. Ukunisela kufanele kwenziwe ekuseni futhi kugweme ukunisela ebusuku ukuvimbela ukutheleleka ngamagciwane. Unganiseli emazingeni okushisa aphezulu emini, njengoba lokhu kungabangela kalula ukusha kotshani okunzima ukukulungisa.
2. Inani lokunisela
Utshani kufanele luniselwe ngokulinganayo nangokulinganayo, futhi ukunisela nge-sprinkler kuyinto enhle. Gwema ukunisela ngokweqile endaweni, okungabangela kalula izifo zezimpande zotshani. Lawula inani lokunisela futhi ugweme amanzi amile phezu komhlaba. Ukubuna kwe-Pythium kuzosakaza amabhaktheriya otshanini obunempilo ngokugeleza kwamanzi.
Ukuthena okunengqondo
Ukusika utshani ehlobo kungandisa umoya kanye nokudlulisa ukukhanya, okukuvumela ukuthi uzivumelanise nendawo eshisayo, kodwa ukusika utshani akufanele kube phansi kakhulu. Ukusika utshani okuphansi ehlobo kuzokwenza buthaka ukukhula kotshani futhi kuvumele izifo ukuba zikusebenzise. Ngesikhathi sokusika utshani ehlobo, ukuphakama kotshani kufanele kwandiswe ngo-1 kuya ku-2 cm (6 cm kufanelekile kakhulu), okungeke nje kuvikele utshani ekulimaleni kwezinga lokushisa eliphezulu, kodwa futhi kuthuthukise ukumelana nezifo zotshani.
Utshani akufanele bugunde ngaphezu kwengxenye eyodwa kwezintathu yobude bonke ngesikhathi, futhi izingcezu zotshani kufanele zisuswe ngokushesha ngemva kokugunda utshani ukuze kugwenywe ukutheleleka ngamagciwane. Uma utshani seluthelelekile, gunda utshani endaweni ethintekile ekugcineni.
Izitshalo zasebusika azimelani namazinga okushisa aphezulu. Ngemva kokungena esikhathini sokushisa, isitshalo sikhula kancane. Inani lokusikwa kufanele lincishiswe kancane. Imvamisa yokusikwa kufanele ibe kanye njalo emavikini amabili kuya kwamathathu. Ukuphakama kwezinti kufanele kukhuliswe kancane ukuze kuthuthukiswe ukumelana kotshani be-turf ezindaweni ezimbi.
Ngaphezu kwalokho,imishini yokugunda utshanikufanele igcinwe ibukhali ukuze kuvinjelwe ukuqhekeka kotshani botshani. Shintsha indlela yokugunda utshani njalo ukuze uvimbele iziqu namaqabunga ekukhuleni ngendlela eqondile lapho ukugunda utshani, okubangela amamaki engqimba futhi kuthinte ikhwalithi; gunda utshani endaweni enelanga noma eyomile ukuze unciphise amathuba okusabalala kwamagciwane; lapho ugunda utshani lapho kuvela izifo, sebenzisa i-blade yomshini wokugunda utshani. Yenza ukubulala amagciwane ukuze uvimbele ukusabalala kwezifo.
Umanyolo wesayensi
Njengoba ihlobo lingena, sebenzisa umanyolo one-nitrogen eningi ngokuqapha, njengoba izifo eziningi zotshani zihlobene nokusetshenziswa ngokweqile komanyolo we-nitrogen. Ukusebenzisa umanyolo we-nitrogen omningi kuzokwenza utshani lukhule futhi lwenze izitshalo zibe mnene futhi zibe namanzi, okukhuthaza ukuhlasela kwamagciwane abangela izifo. Lapho ukukhula kotshani kuba buthaka ehlobo, inani elikhulu lomanyolo oncibilikayo emanzini lingafuthwa emaqabungeni ukuqinisekisa isidingo sotshani somanyolo, ukuthuthukisa ukumelana kwezifo kotshani botshani, nokugwema ingozi yokungenwa yizifo zotshani okubangelwa ukusetshenziswa komanyolo wamakhemikhali.
Ukuvimbela nokulawula izinambuzane nezifo
Ukushisa okuphezulu kanye nomswakama ophezulu ehlobo kungaholela kalula ezifweni eziningi zotshani, njengebala elinsundu elibi, ukubuna kwePythium, ibala lezinhlamvu zemali, ibala lasehlobo, njll. Ngesikhathi esifanayo, kusukela ngoJuni kuya kuSepthemba futhi kuyisikhathi sokwanda kwezinambuzane zotshani. Izinambuzane ezidla amaqabunga njengeSpodoptera litura, izikelemu zezempi, kanye nezibungu zidla amaqabunga otshani; izinambuzane ezingaphansi komhlaba njengemibungu kanye nezikelemu zidla ama-rhizomes otshani, okubangela ukuba utshani bubune futhi bufe.
