Namuhla siyaqhubeka nokwabelana ngeziphakamiso ezithile mayelana nokuphathwa kobusika obuluhlaza okwedlulele ukuze abafundi babhekisele kukho.
H. Ukuphakama Kokusika Utshani
Abaphathi be-turf bathuthukise iziqondiso eziningi mayelana nezilungiselelo zokugcinwa kwenkundla ngosizo lwamakomidi afanele aluhlaza. Ukugcinwa kwenkundla kuhilela kakhulu ukusika utshani, ikakhulukazi utshani obuluhlaza. Kunezici eziningi ezithinta ukumanziswa kotshani obuluhlaza, futhi izidingo zokuphakama kokusika utshani zibonakala kakhulu esidingweni somdlali wegalofu sokudlala kahle enkundleni. Ukuphakama kokusika utshani kubalulekile ebusika botshani. Uma ukuphakama kuphansi kakhulu, ukumelana kwemvelo kotshani kuzothinteka kakhulu. Ukwandisa amandla angaphakathi esitshalo nge-photosynthesis kubalulekile enkambisweni yokuqina. Ubuso beqabunga buyindawo ebalulekile "yokudlulisela". Amandla agcinwa kuqala ebusweni beqabunga bese ethuthwa ohlelweni lwezimpande zesitshalo "njengamandla esitokhwe" ukuze amelane nokubanda okukhulu.
Isinyathelo sokuqala sokucabangela ukusika utshani ukubeka imingcele ekusebenzeni kohlaza ngesikhathi sokuqina, njengokukhetha usuku lokuyeka ukusika utshani bese ushintsha ukusika utshani njalo ngomsebenzi wokugoqa owengeziwe. Uma ukusika utshani kwenziwa, ukuphakama kokusika utshani kufanele kwandiswe kuze kube yilapho ubusika buvalwa. Ukuphakama kokusika utshani kungandiswa ngo-2-3cm, ngaphandle kwalokho utshani buzoba yindawo lapho amagciwane noma izinambuzane zingase zihlale isikhathi eside ebusika, okwenza izinambuzane nezifo zibe zimbi kakhulu ngonyaka ozayo. Ngesikhathi esifanayo, ungqimba lotshani obufile kufanele luklanywe, okusiza ekukhuleni kotshani ngonyaka olandelayo. Ngaphezu kwalokho, i-blade ebukhali yomshini wokusika utshani kufanele igcinwe ukuze kuvinjelwe utshani ukuthi bungadabuki ngesikhathi senqubo yokuqina okubucayi.
Isifinyezo
Izinto ezibangela ukuqina kotshani zifaka phakathi izinga lokushisa eliphansi, amahora amafushane okukhanya kwelanga, kanye nomswakama onciphile enhlabathini nasezitshalweni, kodwa lezi zinto azilawuleki. Ukumelana nokubanda kungashintshashintsha ngokushintsha kwesizini, futhi izinga lokushisa lomhlabathi lidlala indima ebalulekile ekumelaneni nokubanda kwezitshalo. Uma zonke izici zisesimweni esihle, utshani bungafinyelela ezingeni eliphakeme kakhulu lokumelana nokubanda ngemva nje kobusika. Kodwa-ke, isitshalo esingabekezelela amazinga okushisa angaphansi kuka-0 degrees Fahrenheit ngoDisemba singase sikwazi ukumelana namazinga okushisa angaphansi kuka-20 degrees Fahrenheit ekuqaleni kuka-Ephreli. Nakuba utshani lungathuthukisa ukubekezelela kwalo ukubanda ngokufika kobusika, ukubekezelela ukubanda kotshani kuqala ngaphambi kobusika. Ngamafuphi, njengoba ubusika buqhubeka, amandla agcinwe otshanini "ukulwa" nokubanda azoncipha kancane kancane. Lokhu kugcizelela isidingo sokuvundisa kahle utshani ekwindla nasekuqaleni kobusika ukuze kukhuliswe "ukubekezelela ukucindezeleka" kotshani. Inqubo yokuqina iyisinyathelo esibalulekile ekuphumeleleni kobusika botshani, ngakho-keabaphathi bensimukufanele bahlele ubusika futhi balawule izinto eziningi ngangokunokwenzeka ukuze bathuthukise ukusinda kotshani kungakhathaliseki ukuthi bahlangabezana naziphi izimo zezulu. Nakuba isimo sezulu singalawulwa, ukuhlala uxhumana nabadlali akulawulwa. Abaphathi bezinkundla kudingeka bahlale bexhumana nabadlali ukuze babazise ngamalungiselelo enkundla ebusika kanye nemithetho yokuziphatha okudingeka bayilandele.
