Ukusetyenziswa kweekhemikhali ekulawuleni izinambuzane kunye nokwandisa izivuno ekuhlaleni zonke izivuno zemifuno zihlala zishiya imbopheleleko yomhlaba kunye neziqhamo ezifunyenweyo. Oku kungokwemvelo kunempembelelo embi kwimpilo yabantu abayisebenzisayo, ngoko ke abalimi bazama ukusebenzisa uluntu okanye ubuncinane iindlela ezingasiphepheli kwisisombululo sale njongo. Ngaloo ndlela, ngamanye amaxesha athetha ukusebenzisa, umzekelo - i- boric acid .
Ngaba kunokwenzeka ukuba ufefe iitamatisi nge-boric acid?
Ewe, ewe, kuba kulu lungiselelo uqulethe i-tomato yesitshixo esizalisekileyo isiqhamo-bergon. Ukusetyenziswa kokugqoka okuphezulu (ukutshiza) ukucebisa izityalo kunye nokukhuthaza ukuhambelana ngokukhawuleza. Kodwa le nyango ikhuthazwa kuphela kwixesha elithile.
Iitamatyiti ziyakutyalwa nini nge-boric acid?
I-boron inceda isityalo siphume izixhobo eziyimfuneko ekuphuhlisweni kwayo ngokupheleleyo kwiindawo ezinzulu zomhlaba, ngaphandle koko kukhuthaza ukukhula kwemifuno kunye nokwakhiwa kwama-ovari. Yingakho kucetyiswa ukuba yongeze i-harrow ngamaxesha amaninzi ngexesha ngalinye:
- phambi kokuqhakaza, xa kwakhiwa amaqabunga;
- ngethuba lembali;
- ngexesha lokuchuma.
Ukuphindaphinda ukucubungula akunakwenzeka ngaphambi kweentsuku eziyi-8-10. Ukuba, emva kokuqhumisa kokuqala, izityalo zaqala ukubonakala zibi, ngoko ukusetyenziswa kwesi sidakamizwa kumele kumiswe ngokupheleleyo.
Ukongeza isongezelelo se-boric acid kuza kunceda ukwandisa inani leentyatyambo, gcina amabhondi asele asetshaneni kwaye avimbele ukubola kweziqhamo. Xa zenziwa, ukwanda kwimiqhamo evuthiwe ngo-20% kunye nokuphuculwa kwintambo yabo (baya kuba ushukela ophezulu) bayaphawulwa.
Kwakhona, olu unyango lunokukunceda ukukhusela izifo zentamatyambo ezifana ne-phytophthora. Kule nto, kufuneka iphathwe kwinqanaba lesibini likaJuni ngeveki emva kokuphalaza ngesisombululo esinamandla se- potassium permanganate , kwaye emva kwayo, i-iodine kufuneka isetyenziswe.
Ngendlela efanelekileyo ukufefa iitamatisi nge-boric acid?
Le nkqubo ilula kakhulu. Okokuqala, isisombululo senziwe, kwaye emva kokuba sele sehlile, izityalo zifakwe kwizinga eli-1 litre nganye nge-10 m & sup2. Ngenxa yoko, kufuneka kuvele ukuba amaqabunga kunye nama-ovari kwiindawo ezihlambulukileyo kufuneka zihlanjululwe kakuhle.
Ngokuxhomekeke kwinjongo yokusetyenziswa, kukho iindlela ezininzi zokulungiselela isisombululo se-boric acid ekusebenziseni utamatisi:
- Ukugcina ii-ovari. Igramu enye ye-asidi ichithwe ngokupheleleyo kumanzi ashushu. Isisombululo esiphumela siphuhlile. Emva koko, yongeza amanzi abandayo kuwo, ukwenzela ukuba inani elipheleleyo lilitre eli-1; I-5-10 g yesilwanyana ichithwa kwi-10 ilitha yamanzi kwaye ixutywe.
- Ukukhuselwa kumayeza. Siphalaza i-1 tsp. i-boric acid kwibhakethi ezili-10 ilitha zamanzi uze udibanise uze udibaniswe ngokupheleleyo.
Kubaluleke kakhulu ukulungiselela ukugqoka okuphezulu kwiitamatisi ukugcina ubungakanani obucacileyo, kuba ubuninzi be-boron buphazamisa izityalo. Ukuba
Ukutshiza utamatisi nge-boric acid kunconywa ngexesha elingapheliyo losuku (kusasa okanye kusihlwa) ngokungabikho kwemimoya nemvula. Sebenzisa isipilisi ngefayili efanelekileyo.
Ukwazi oko kunokufafaza iitamatati, ukwenzela ukwandisa umgangatho kunye nobungakanani besityalo, ngaphezu kweekhemikhali zendalo, unokufumana imifuno engaphezulu enokuthi inikwe abantwana.
