Ukusetshenziswa kwamakhemikhali ekulawuleni izinambuzane kanye nokwandisa izivuno ekutshalweni kwanoma yiziphi izitshalo zemifino njalo kushiya impendulo kokubili isimo somhlabathi nezithelo ezitholakalayo. Lokhu ngokwemvelo kunethonya elibi empilweni yabantu abayisebenzisayo, ngakho abalimi balinga ukusebenzisa izindlela zemvelo noma okungenani ezingaphephile kwisisombululo sale migomo. Ngalokhu, izindlela ezingezona ezejwayelekile ngezinye izikhathi zisetshenziswa, isibonelo - boric acid .
Kungenzeka yini ukufafaza utamatisi nge-boric acid?
Yiqiniso, yebo, ngoba kulokhu kulungiselelwa kuqukethe okudingekayo utamatisi for element full izithelo bearing - boron. Ukusetshenziswa kwe-foliar top dressing (ukuphalaza) ukucebisa izitshalo nayo kukhuthaza ukufana okusheshayo. Kodwa lokhu ukwelashwa kunconywa kuphela ezikhathini ezithile.
I-tomate ingafafazwa nini ne-boric acid?
I-boron isiza isitshalo sikhiphe izakhi ezidingekayo ekuthuthukisweni kwayo okugcwele kusukela ekujuleni kwenhlabathi, ngaphandle kwalokho kuyashukumisa ukukhula kwefihlekile nokwakhiwa kwama-ovari. Yingakho kunconywa ukuba wengeze i-harrow nge-acid izikhathi eziningana ngonyaka ngamunye:
- ngaphambi kokusila, lapho kumile amaqabunga;
- ngesikhatsi ubukhulu besisindo;
- ngesikhathi se-fruiting.
Phinda ukucubungula kungabi khona ngaphambi kwezinsuku ezingu-8-10. Uma, ngemva kokufaka umquba wokuqala, izitshalo zaqala ukubheka okubi, ngakho ukusetshenziswa kwalesi sidakamizwa kufanele kumiswe ngokuphelele.
Ukwengeza ukwesekwa kwe-boric acid kuzosiza ukwandisa inani lezimbali, ugcine izinhlamvu ezivele zakhiwe ehlathini futhi zivimbele ukubola kwesithelo. Uma kwenziwa, ukwanda kwemifino evuthiwe ngo-20% nokuthuthukiswa kokunambitheka kwabo (baba yishukela ngaphezulu) kubonakala.
Futhi, lokhu ukwelashwa kungasiza ekuvimbeleni ukuthuthukiswa kwezifo zamatamatisi ezifana ne-phytophthora. Ngalokhu, kudinga ukwelashwa engxenyeni yesibili kaJuni ngesonto ngemuva kokuphalaza ngesisombululo esibuthakathaka se- potassium permanganate , futhi emva kwalokho, i-iodine kumele isetshenziswe.
Kanjani kahle ukufafaza utamatisi nge-boric acid?
Le nqubo ilula kakhulu. Okokuqala, isisombululo senziwa, futhi ngemva kokuba sele sehlile, izitshalo zifakwe ngezinga lezinga elilodwa le-10 m & sup2. Ngenxa yalokho, kufanele kuvele ukuthi amaqabunga nama-ovari emahlathini kufanele aphethwe kahle.
Kuye ngenhloso yokusebenzisa, kunezinketho eziningi zokulungiselela isisombululo se-boric acid ekucubunguleni utamatisi:
- Ukugcina ama-ovari. Igramu eyodwa ye-asidi isuke iqedwe ngokuphelele emanzini ashisayo. Isixazululo esiphelele siphelile. Emva kwalokho, engeza amanzi abandayo kuwo, ukuze ivolumu ingqikithi ilitha elilodwa; I-5-10 g yesidakamizwa ithululelwa ku-10 amalitha amanzi futhi ixutshwe.
- Ukuvikelwa ngokumelene nama-phytoplores. Siphululela 1 tsp. i-boric acid ebhakedeni ngamalitha angu-10 amanzi bese uxuba uze uqedwe ngokuphelele.
Kubaluleke kakhulu ukulungisa ukugqoka okunjalo kumatamatisi ukugcina isilinganiso esinqunyiwe, ngoba ukudlula kwe-boron kuyathinta izitshalo. Uma
Ukupaka utamatisi nge-boric acid kunconywa ngesikhathi esingapheli sosuku (ekuseni noma kusihlwa) ngokungabikho kwemimoya nemvula. Sebenzisa i-spray nge-spray emihle.
Ukwazi ukuthi ungafafazwa kanjani utamatisi, ukuze ukwandise ikhwalithi nobuningi besitshalo, ngaphezu kwamakhemikhali endabuko, ungathola imifino eminingi engokwemvelo enganikezwa ngisho nezingane.
