Ungayilawula Kanjani I-Meloidogyne Incognita?

I-Meloidogyne incognita iyisinambuzane esivamile kwezolimo, esiyingozi futhi esinzima ukusilawula. Ngakho-ke, i-Meloidogyne incognita kufanele ilawulwe kanjani?

Izizathu zokulawula okunzima kwe-Meloidogyne incognita:

1. Lesi sinambuzane sincane futhi sinendawo yokucasha eqinile

I-Meloidogyne incognita uhlobo lwezinambuzane ezithwalwa enhlabathini ezinekhono elincane lokuhlasela, ezidla izimuncagazi ezitshalweni eziningi, okhula, njll.; Ijubane lokuzala liyashesha, futhi isibalo sezinambuzane kulula ukuziqoqa ngobuningi obukhulu.

2. Ukuhlasela impande, kunzima ukuyibona

Uma isitshalo sibonisa izimpawu, izimpande zihlaselwe yi-nematode, okubangela umonakalo esitshalweni. Lesi sitshalo siziphatha ngendlela efanayo nezifo ezithwalwa yinhlabathi njengokubuna kwamagciwane, futhi sidukiswa kalula yizici ezisobala.

3. Ukuzivumelanisa nezimo okuqinile kwemvelo

Ngokuvamile isebenza ezingqimbeni zomhlabathi ezingaba ngu-15-30cm, ifinyelela ekujuleni okungafika kumamitha angu-1.5. Ingathelela izidalwa eziningi futhi ingaphila iminyaka emi-3 ngisho noma kungekho zimo ezibangelwa yizinambuzane.

4. Izinqubo eziyinkimbinkimbi zokususa

Kunezinhlobo eziningi zokudluliswa kwe-Meloidogyne incognita yi-Pathogen. Amathuluzi okulima angcolile, izithombo ezinezibungu, kanye nenhlabathi ethwalwa nezicathulo ngesikhathi sokusebenza konke kube yizimbangela zokudluliswa kwe-Meloidogyne incognita.

Izindlela zokuvimbela nokulawula:

1. Ukukhethwa kwezinhlobo zezitshalo

Kumelwe sikhethe izinhlobo noma iziphunzi zezimpande ezimelana ne-Meloidogyne incognita, futhi sikhethe izinhlobo zemifino ezimelana nezifo noma izifo, ukuze sikwazi ukunciphisa kakhulu ukulimala kwezifo ezahlukahlukene.

2. Ukukhuliswa kwezithombo enhlabathini engenazifo

Uma sikhulisa izithombo, kufanele sikhethe inhlabathi engenaso isifo se-Meloidogyne incognita sokukhuliswa kwezithombo. Inhlabathi enesifo se-Meloidogyne incognita kufanele ihlanzwe ngamagciwane ngaphambi kokukhulisa izithombo. Kufanele siqinisekise ukuthi izithombo azithelelekile. Kungale ndlela kuphela lapho singanciphisa khona ukwanda kwesifo esigabeni sobudala.

3. Ukulima inhlabathi ejulile kanye nokujikeleza kwezitshalo

Ngokuvamile, uma simba sijule enhlabathini, sidinga ukufinyelela amasentimitha angu-25 noma ngaphezulu ukuze silethe ama-nematode engqimbeni ejulile yomhlabathi phezulu. Ngalesi sikhathi, inhlabathi engaphezulu ngeke ikhululeke nje kuphela, kodwa futhi izonciphisa okuqukethwe amanzi ngemva kokuchayeka elangeni, okuyinto engasizi ekusindeni kwama-nematode.

4. Ukushisa okuphezulu, ukwelashwa kwenhlabathi

Uma kuyi-Meloidogyne incognita endlini eluhlaza okotshani, singasebenzisa ukushisa okuphezulu ehlobo ukubulala iningi lama-nematode. Ngesikhathi esifanayo, singaphinde sibolise izinsalela zezitshalo i-Meloidogyne incognita ezithembele kuzo ukuze ziphile enhlabathini.

Ngaphezu kwalokho, uma inhlabathi iyisihlabathi, kufanele sithuthukise inhlabathi unyaka nonyaka, okunganciphisa ngempumelelo umonakalo we-Meloidogyne incognita.

5. Ukuphathwa kwensimu

Singafaka umquba obolile ensimini futhi sandise umanyolo we-phosphorus kanye ne-potassium, okungathuthukisa ukumelana kwezifo kwezitshalo. Kumelwe sikhumbule ukuthi akumelwe sifake umquba ongavuthiwe, okuzokwenza kube nzima kakhulu ukuvela kwe-Meloidogyne incognita.

6. Khulisa ukusetshenziswa komanyolo webhayoloji osebenzayo futhi uqinise ukuphathwa kokutshala

Sidinga ukusebenzisa umanyolo webhayoloji owengeziwe wokulawula i-nematode (isibonelo, equkethe i-Bacillus thuringiensis, i-spore onsomi onsomi, njll.) ukuze sithuthukise izitshalo ezincane zenhlabathi, sivimbele ngempumelelo ukuvela kwe-nematode, sithuthukise ukukhula, futhi sinciphise ukulimala kwe-Meloidogyne incognita.
