Unesitshalo esihle sezotamatisi esakhula ku-greenhouse, kanti ngolunye usuku waphawula ukuthi izithelo eziluhlaza eziboshwe zaphenduka zaba mnyama. Kwenzekani? Kungani amaqabunga nezithelo zezotamatisi zikhula zibe mnyama endaweni yokushisa? Uzothola izimpendulo zale mibuzo kulesi sihloko.
Utamatisi omnyama ku-greenhouse - izizathu
Isizathu esiningi kakhulu sokutshala izithelo zotamatisi yisifo sokulimala okuphelile , noma ukubola okubomvu. Okokuqala, ingxenye engenhla yamaqabunga e-tomato ishintshiwe, ahlanganiswe nezindawo ezimnyama. Khona-ke lesi sifo sidlulela ezingxenyeni ezingezansi zamaqabunga, lapho kuvela khona ukugqoka okubomvu.
Lapho i-greenhouse ingenamandla umoya futhi umswakama ophezulu ugcinwa kuwo, i-phytophthora isakazeka ngokushesha ekutheni izithelo zamatamatisi eziluhlaza futhi ezivuthiwe ziqala ukubola futhi azifaneleki ukudla. Futhi uma kunomthelela omkhulu emakhasini emini nasebusuku, amazolo awela futhi kuvele ukuqhuma (lokhu kwenzeka ngo-Agasti), khona-ke utamatisi omnyama ku-greenhouse ngokuvamile ngenxa yalezi zici zezulu. Kubangelwa ekubukeni kwesifo ukuchelela utamatisi akusikho ngaphansi kwempande, kodwa emaqabunga.
Ukuze ugweme ukulimala okuphelile, kuyadingeka ukwelapha imbewu nge- potassium permanganate ngaphambi kokutshala, futhi ukhethe nezinhlobonhlobo zamatamatisi eziphikisana nalesi sifo.
Esinye isifo esithinta utamatisi ngale ndlela i-vertex noma i-gray gray. Kungaba khona ngenxa yokuntuleka kwezici ezithile zokulandelela, ngokuvamile i-calcium. Utamatisi ku-abamba ukushisa, othinteka yi-vertex ukubola, vula abamnyama kusuka ngezansi. Ukuthambisa okungavamile nokungavamile kwezitshalo kungabangela ukubonakala kobumnyama obunjalo.
Imiphumela emihle ekulwa nokubola kwe-vertex ingatholakala ngokushintsha ukutshala kwezitshalo ezahlukene. Uma utamatisi etshalwe endaweni efanayo njalo eminyakeni emine, kuzosiza ukugwema ukubonakala kobumnyama ezitshalweni.
Kubangela ukunyamala kwetamatisi kanye nama-asidi amaningi kakhulu enhlabathini. Lokhu kungenzeka uma ukwedlula izitshalo ezineziqu eziqukethe nitrogen.
