Uma izinga lokushisa lifinyelela ngaphezu kwama-28°C, i-photosynthesis yotshani botshani besikhathi esipholile iyancipha futhi ukwakheka kwama-carbohydrate kuyancipha. Ekugcineni, ukusetshenziswa kwama-carbohydrate kudlula ukukhiqizwa kwawo. Phakathi nalesi sikhathi, utshani besikhathi esipholile buthembele kuma-carbohydrate agciniwe ukuze bulondoloze impilo. Ngisho noma isitshalo silele futhi amaqabunga elahlekelwa umbala wawo oluhlaza, isitshalo sisaphefumula. Uma siyeka ukuphefumula, isitshalo sizofa.
Uma izinga lokushisa lomhlabathi likhuphuka, izinga lokuphefumula liyakhuphuka ngempela. Ngaphezu kwalokho, ukwehla kwe-photosynthesis ngaphansi kwezinga lokushisa eliphezulu kubangela ukuthi ukusetshenziswa kwama-carbohydrate kusheshe kunokukhiqiza kwawo. Lesi yisona sizathu esiyinhloko sokwehla kwe-bentgrass yasehlobo. Ucwaningo luphinde lwaphetha ngokuthi umehluko phakathi kokukhiqizwa kwama-carbohydrate nokusetshenziswa kwawo uzokwehla lapho ukuphakama kokusika kukhushulwa.
Iningi labadlali begalofu lidinga indawo yokudlala eluhlaza, futhi ukulala isikhathi eside kuzobangela ukufa kwezitshalo. Ukunisela kuyindlela ebalulekile yokuvimbela ukulala, kanti ezinye izinyathelo zingathuthukisa ikhono lezitshalo lokugwema ukulala, ukusinda ukulala, nokululama ekulale. Izinyathelo eziningi kumele ziqaliswe ngaphambi kokuqala kokucindezeleka kwasehlobo, abanye abaphathi abakubiza ngokuthi “ukulungisa isimo sangaphambi kokucindezeleka”, kanje:
1. Ukukhulisaukuphakama kokusikakungenza uhlelo lwezimpande zotshani lujule futhi lube lukhuni;
2. Ezinye izinguquko zesimo somzimba, ngaleyo ndlela kuthuthukiswe ukumelana nesomiso. Nciphisa ukuchelela ngaphandle kokuthinta ikhwalithi yobuso botshani. Ukucindezeleka kwesomiso okuncane phakathi kokuchelela okubili kunciphisa ukukhula kwamagatsha futhi kukhuthaze ukukhula kwezimpande. Ngokufanayo, ukuchelela okulingene entwasahlobo kungakhuthaza ukukhula kwezimpande okujulile ukuze kumelwane nokushisa kwasehlobo kanye nesomiso. Kodwa-ke, ngaphansi kokucindezeleka kokushisa okuphezulu, kumele kuqinisekiswe ukuthi kutholakala amanzi anele ukuze utshani lukwazi ukunciphisa izinga lokushisa lesitshalo ngokuphefumula.
3. Gwema ukufaka i-nitrogen entwasahlobo nasehlobo ukuvimbela ingxenye engaphezulu komhlabathi yesitshalo ukuthi ingakhuli ngokushesha kakhulu futhi yonakalise ukukhula kwezimpande.
4. Khetha izinhlobo nezinhlobo zotshani ezimelana nokushisa nesomiso
5. Khuthaza ukukhula kwezimpande kanye namandla: Thatha izinyathelo zokukhuthaza ukukhula kwezimpande unyaka wonke. Izimpande ezijulile neziqinile zingathuthukisa ukumelana nesomiso kwengadi futhi zenze isitshalo sikwazi ukumunca amanzi amaningi enhlabathini ebanzi. Ukubhoboza imigodi kwandisa ukungena kwenhlabathi futhi kuvumela ukukhula kwezimpande okuthuthukile.
6. Ukupholisa inhlabathi: Ukufutha umoya opholile uye endaweni eluhlaza ngepayipi lokukhipha amanzi kusetshenziswa kakhulu emazweni aseNtshonalanga.
7. Ukupholisa utshani:Ukufutha nokupholisautshani ngokuhwamuka.
8. Ukunciphisa ukunyathela: Nciphisa ukunyathela noma ukungena otshanini ehlobo.
