Ungayilawula njani iMeloidogyne Incognita?

I-Meloidogyne incognita sisinambuzane esixhaphakileyo kwezolimo, esiyingozi kwaye kunzima ukusilawula. Ngoko ke, i-Meloidogyne incognita ifanele ilawulwe njani?

Izizathu zokuba kunzima ukulawula i-Meloidogyne incognita:

1. Esi sinambuzane sincinci kwaye sinomzimba oqinileyo ofihlakeleyo

I-Meloidogyne incognita luhlobo lwezinambuzane ezithwalwa ngumhlaba ezinazo zombini, amandla okuhlasela aqinileyo, iincukuthu kwizityalo ezininzi, ukhula, njl.njl.; Isantya sokuzala siyakhawuleza, kwaye inani lezinambuzane kulula ukuziqokelela ngobuninzi.

2. Ukungena ingcambu, kunzima ukuyibona

Xa isityalo sibonisa iimpawu, iingcambu zihlaselwe yi-nematodes, nto leyo ebangela umonakalo kwisityalo. Isityalo siziphatha ngendlela efanayo nezifo ezithwalwa ngumhlaba ezifana nokubola kwebhaktheriya, kwaye kulula ukulahlekiswa ziimpawu ezibonakalayo.

3. Ukuguquguquka okuqinileyo kokusingqongileyo

Ihlala isebenza kwiindawo zomhlaba ezimalunga ne-15-30cm, ifikelela kubunzulu obufikelela kwi-1.5 yeemitha. Ingosulela izidalwa ezininzi kwaye ingaphila iminyaka emi-3 nokuba akukho meko ibangelwa yizo.

4. Iinkqubo ezintsonkothileyo zokususa

Kukho iindlela ezininzi zokudlulisela iMeloidogyne incognita kwizifo. Izixhobo zasefama ezingcolisiweyo, izithole ezineempethu, kunye nomhlaba othwalwa zizihlangu ngexesha lokusebenza zonke ziye zaba ngabalamli bokudluliselwa kweMeloidogyne incognita.

Iindlela zokuthintela nokulawula:

1. Ukukhethwa kweentlobo zezityalo

Kufuneka sikhethe iintlobo okanye iingcambu ezimelana neMeloidogyne incognita, kwaye sikhethe iintlobo zemifuno ezimelana nezifo okanye izifo, ukuze sikwazi ukunciphisa kakhulu umonakalo wezifo ezahlukeneyo.

2. Ukukhulisa izithole kumhlaba ongenazifo

Xa sikhulisa izithole, kufuneka sikhethe umhlaba ongenasifo seMeloidogyne incognita sokukhuliswa kwezithole. Umhlaba onesifo seMeloidogyne incognita kufuneka ubulawe iintsholongwane ngaphambi kokuba kukhuliswe izithole. Kufuneka siqinisekise ukuba izithole azisuleleki. Kungale ndlela kuphela esinokunciphisa ukwanda kwesifo xa sele sikhulile.

3. Ukulima umhlaba nzulu kunye nokujikeleza izityalo

Ngokubanzi, ukuba sigrumba nzulu emhlabeni, kufuneka sifikelele kwiisentimitha ezingama-25 nangaphezulu ukuze sizise ii-nematodes kumaleko womhlaba onzulu kumphezulu. Ngeli xesha, umhlaba ongaphezulu awuyi kukhululeka nje kuphela, kodwa uya kunciphisa nomthamo wamanzi emva kokuba ubekwe elangeni, nto leyo engayi kunceda ukusinda kwee-nematodes.

4. Indlu eluhlaza enobushushu obuphezulu, unyango lomhlaba

Ukuba yiMeloidogyne incognita ekwigreenhouse, singasebenzisa ubushushu obuphezulu ehlotyeni ukubulala uninzi lweenematode. Kwangaxeshanye, singabolisa neentsalela zezityalo ezixhomekeke kwiMeloidogyne incognita ukuze ziphile emhlabeni.

Ukongeza, xa umhlaba unesanti, kufuneka siphucule umhlaba unyaka nonyaka, nto leyo enokunciphisa ngempumelelo umonakalo we-Meloidogyne incognita.

5. Ulawulo lwentsimi

Singafaka umgquba obolileyo entsimini size songeze i-phosphorus kunye nesichumiso se-potassium, nto leyo enokuphucula ukumelana nezifo kwizityalo. Kufuneka sikhumbule ukuba akufuneki sisebenzise umgquba ongavuthwanga, nto leyo eya kwenza kube nzima ngakumbi ukuvela kwe-Meloidogyne incognita.

6. Ukwandisa ukusetyenziswa kwezichumisi zebhayoloji ezisebenzayo kunye nokuqinisa ulawulo lokulima

Sidinga ukufaka isichumisi sebhayoloji esilawula i-nematode (umzekelo, equlethe i-Bacillus thuringiensis, i-spore emfusa okwesibhakabhaka, njl.njl.) ukuphucula izityalo ezikhula emhlabeni, ukuthintela ngempumelelo ukuvela kwe-nematodes, ukuphucula ukukhula, kunye nokunciphisa ubungozi be-Meloidogyne incognita.
