Uyilawula njani iMeloidogyne Incognita?

I-Meloidogyne incognita sisitshabalalisi esixhaphakileyo kwezolimo, esiyingozi kwaye kunzima ukuyilawula.Ke, iMeloidogyne incognita kufuneka ilawulwe njani?

Izizathu zolawulo olunzima lwe-Meloidogyne incognita:

1. Isinambuzane sincinci kwaye sinezinto ezifihlakeleyo ezinamandla

I-Meloidogyne incognita luhlobo lwesitshabalalisi esithwalwa ngumhlaba esinomntu omncinane, isakhono esinamandla sokuhlasela, i-parasitic kwizityalo ezininzi, ukhula, njl.njl;Isantya sokuzala sikhawuleza, kwaye isiseko sabemi bezinambuzane kulula ukuqokelela ngobuninzi obukhulu.

2. Ukuhlasela ingcambu, kunzima ukuyibona

Xa isityalo sibonisa iimpawu, iingcambu ziye zahlaselwa yi-nematodes, ezenza umonakalo kwisityalo.Isityalo siziphatha ngendlela efanayo kwizifo ezithwalwa ngumhlaba ezifana nokunyangwa kwebhaktiriya, kwaye sikhohliswa lula ziimpawu ezicacileyo.

3. Ukuguquguquka okuqinileyo kokusingqongileyo

Idla ngokusebenza kumaleko omhlaba amalunga ne-15-30cm, ifikelele kubunzulu obuyi-1.5 yeemitha.Inokosulela iinginginya ezininzi kwaye inokuphila iminyaka emi-3 naphantsi kweemeko zomkhosi.

4. Iinkqubo eziyinkimbinkimbi zokuphelisa

Zininzi iPathogen yosulelo lweMeloidogyne incognita.Izixhobo zasefama ezosulelekileyo, izithole ezineentshulube, kunye nomhlaba othwelwe ngezihlangu ngexesha lokusebenza zonke ziye zaba ngabalamleli bosasazo lwe-Meloidogyne incognita.

Uthintelo kunye neendlela zokulawula:

1. Ukukhethwa kweentlobo zezityalo

Kufuneka sikhethe iintlobo okanye i-rootstocks echasene ne-Meloidogyne incognita, kwaye sikhethe iintlobo zemifuno ezichasene nezifo okanye izifo, ukuze sinciphise kakhulu ingozi yezifo ezahlukahlukeneyo.

2. Ukunyuswa kwezithole kumhlaba ongenazifo

Xa ukhulisa izithole, kufuneka sikhethe umhlaba ngaphandle kwesifo seMeloidogyne incognita sokukhulisa izithole.Umhlaba onesifo i-Meloidogyne incognita kufuneka ubulawe iintsholongwane phambi kokunyuswa kwezithole.Kufuneka siqinisekise ukuba izithole azosuleleki.Kuphela ngale ndlela sinokunciphisa iziganeko zezifo kwinqanaba labantu abadala.

3. Ukulima umhlaba nzulu kunye nokujikeleziswa kwezityalo

Ngokuqhelekileyo, ukuba sigrumba nzulu emhlabeni, kufuneka sifikelele kwi-25 centimeters okanye ngaphezulu ukuze sizise i-nematodes kumhlaba onzulu emhlabeni.Ngeli xesha, umhlaba ongaphezulu awuyi kukhululeka nje kuphela, kodwa uphinde unciphise umthamo wamanzi emva kokuba ubekwe elangeni, okungekho luncedo ekusindeni kwe-nematodes.

4. Ukushisa okuphezulu kwe-greenhouse, unyango lomhlaba

Ukuba yi-Meloidogyne incognita kwi-greenhouse, sinokusebenzisa ubushushu obuphezulu ehlotyeni ukubulala uninzi lwe-nematodes.Kwangaxeshanye, sinokubolisa iintsalela zesityalo iMeloidogyne incognita exhomekeke kuyo ukuze siphile emhlabeni.

Ukongezelela, xa umhlaba unesihlabathi, kufuneka siphucule umhlaba ngonyaka, onokunciphisa ngokufanelekileyo umonakalo we-Meloidogyne incognita.

5. Ulawulo lwentsimi

Singafaka umgquba obolileyo entsimini kwaye sandise i-phosphorus kunye nesichumiso se-potassium, esinokuphucula ukuxhathisa izifo zezityalo.Kufuneka sikhumbule ukuba akufuneki sisebenzise umgquba ongekavuthwa, nto leyo eya kwenza kube mandundu ngakumbi ukwenzeka kwe-Meloidogyne incognita.

6. Ukwandisa ukufakwa kwezichumiso zebhayoloji ezisebenzayo nokomeleza ulawulo lokulima

Kufuneka sisebenzise isichumiso sebhayoloji yokulawula i-nematode (umzekelo, equlethe i-Bacillus thuringiensis, i-purple spore, njl.njl.) ukuphucula umhlaba we-microbial flora, ukuthintela ngokufanelekileyo ukwenzeka kwe-nematodes, ukwandisa ukukhula, kunye nokunciphisa ingozi ye-Meloidogyne incognita.
