Lapho amazinga okushisa efinyelela ngenhla 28 ℃, i-photosynthesis yonyaka opholile wotshani utshani iyancipha kanye ne-carbohydrate synthession iyancipha. Ekugcineni, ukusetshenziswa kwe-carbohydrate kudlula ukukhiqizwa kwayo. Ngalesi sikhathi, utshani obupholile bonyaka buthembela kuma-carbohydrate alo agcinwe ukuze alondoloze impilo. Noma isitshalo sithule futhi amaqabunga elahlekelwa umbala wawo oluhlaza, isitshalo sisaphikisani. Lapho iyeka ukuphefumula, isitshalo sizokufa.
Lapho izinga lokushisa lomhlabathi likhuphuka, izinga lokuphefumula empeleni liyaphuma. Ngaphezu kwalokho, ukuncishiswa kwe-photosynthesis ngaphansi kokushisa okuphezulu kubangela ukusetshenziswa kwe-carbohydrate kusheshe kunokukhiqizwa kwalo. Lesi yisizathu esiyinhloko sokwehla kwe-Summer Bengrass. Lolu cwaningo luphinde lwaphetha ngokuthi umehluko phakathi kokukhiqizwa kanye nokusetshenziswa kwe-carbohydrate kuzokwehla lapho ukuphakama okumanzi kukhuphuka.
Iningi labadlali begalofu lidinga indawo eluhlaza eluhlaza okwesibhakabhaka, futhi ukubulala isikhathi eside kuzodala ukufa kwezitshalo. Ukunisela kuyindlela ebalulekile yokuvimbela i-doormancy, nezinye izinyathelo futhi kungathuthukisa amandla ezitshalo ukugwema ukudonswa kabusha, ukusinda okutholwe phansi, futhi alulame kusuka ku-dollarmin. Izinyathelo eziningi kumele zisetshenziswe ngaphambi kokuqala kokuxineka kwehlobo, abanye abaphathi babiza "isimo sangaphambi kwengcindezi", ngokulandelayo:
1. Ukukhulisa i-Ukuphakama Ukuphakamaangenza uhlelo lwezimpande ze-Lawn
Izinguquko ze-morphological, ngaleyo ndlela zithuthukisa ukumelana nesomiso. Ukunciphisa ukuchelela ngaphandle kokuthinta ikhwalithi ephezulu yotshani. Ukuxineka kwesomiso okumnene phakathi kokunisela okubili kunciphisa ukukhula kwegatsha futhi kuthuthukisa ukukhula kwezimpande. Ngokufanayo, ukunisela okulinganiselayo entwasahlobo kungakhuthaza ukukhula kwezimpande okujulile ukumelana nokushisa kwehlobo nesomiso sesomiso. Kodwa-ke, ngaphansi kwengcindezi ephezulu yokushisa, ukuhlinzekwa kwamanzi anele kufanele kuqinisekwe ukuze umthetho unciphise izinga lokushisa kwezitshalo ngokuvutha.
3. Gwema uhlelo lwe-nitrogen entwasahlobo nasehlobo ukuvikela ingxenye engenhla yesitshalo kusuka ekukhuleni ngokushesha okukhulu nokulimaza ukukhula kwezimpande.
4. Khetha ukushisa kanye nezinhlobo zotshani ezivinjelwe kanye nezinhlobonhlobo
5. Khuthaza ukukhula kwezimpande namandla: Thatha izinyathelo zokuthuthukisa ukukhula kwezimpande unyaka wonke. Izimpande ezijulile nezempi zingathuthukisa ukumelana kwesomiso zotshani bese kunika amandla isitshalo ukuba sithole amanzi amaningi kusuka kububanzi benhlabathi. Izimbobo zokushayela zikhulisa inhlabathi permeability futhi zivumela ukukhula okwengeziwe kwezimpande.
6. Ukupholisa inhlabathi: ukushaya umoya okupholile kokubeka okuluhlaza okotshani ngepayipi lokudonsa amanzi kusetshenziswa kabanzi emazweni asentshonalanga.
7. Ukupholisa utshani:Ukufafaza nokupholisautshani ngokuhwamuka.
8. Ukunciphisa ukunyathela: nciphisa ukunyathela noma ukungena ku-lown ehlobo.
