Uyilawula kanjani i-Meloidogyne Incognita?

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

Izizathu zokulawula okunzima kwe-Meloidogyne incognita:

1. Isinambuzane sincane futhi sinokucasha okuqinile

I-Meloidogyne incognita iwuhlobo lwesilokazane esithwalwa umhlabathi esinomuntu omncane, ikhono eliqinile lokuhlasela, i-parasitic ezitshalweni eziningi, ukhula, njll;Isivinini sokuzalanisa siyashesha, futhi isizinda sabantu sezinambuzane kulula ukunqwabelana ngobuningi.

2. Ukuhlasela impande, kunzima ukuyibona

Lapho isitshalo sibonisa izimpawu, izimpande ziye zahlaselwa ama-nematode, okwenza umonakalo esitshalweni.Lesi sitshalo siziphatha ngendlela efanayo nezifo ezithwalwa umhlabathi njenge-bacterial wilt, futhi sidukiswa kalula izici ezisobala.

3. Ukuvumelana nezimo kwemvelo okuqinile

Ivamise ukusebenza ezingqimbeni zomhlabathi ezingaba ngu-15-30cm, ifinyelele ekujuleni okungafika kumamitha ayi-1.5.Ingathelela ababungazi abaningi futhi ingaphila iminyaka emi-3 ngisho nangaphansi kwezimo zokusingatha.

4. Izinqubo eziyinkimbinkimbi zokuqeda

Kunokudluliswa kwe-Pathogen okuningi kwe-Meloidogyne incognita.Amathuluzi epulazi angcolisiwe, izithombo ezinezibungu, nomhlabathi othwelwe ngezicathulo ngesikhathi sokusebenza konke sekuphenduke abalamuli bokudluliselwa kwe-Meloidogyne incognita.

Izindlela zokuvimbela nokulawula:

1. Ukukhethwa kwezinhlobo zezitshalo

Kumelwe sikhethe izinhlobo noma iziphunzi ezimelana ne-Meloidogyne incognita, futhi sikhethe izinhlobo zemifino ezimelana nezifo noma izifo, ukuze sinciphise kakhulu ukulimala kwezifo ezihlukahlukene.

2. Ukukhuliswa kwezithombo emhlabathini ongenazifo

Lapho sikhulisa izithombo, kufanele sikhethe inhlabathi ngaphandle kwesifo se-Meloidogyne incognita sokukhulisa izithombo.Umhlabathi one-Meloidogyne incognita disease kufanele ubulawe amagciwane ngaphambi kokukhuliswa kwezithombo.Kufanele siqinisekise ukuthi izithombo azitheleleki.Kungale ndlela kuphela lapho singakwazi ukunciphisa izinga lezifo esiteji sabantu abadala.

3. Ukulima kwenhlabathi ejulile nokushintshanisa izitshalo

Ngokuvamile, uma simba sijule emhlabathini, sidinga ukufinyelela amasentimitha angu-25 noma ngaphezulu ukuze silethe ama-nematode ongqimba lomhlabathi ojulile phezulu.Ngalesi sikhathi, inhlabathi engaphezulu ngeke igcine ngokuxega kuphela, kodwa futhi izonciphisa umthamo wamanzi ngemva kokuchayeka elangeni, elingenakukwazi ukuphila kwe-nematodes.

4. I-greenhouse yokushisa ephezulu, ukwelashwa kwenhlabathi

Uma kuyi-Meloidogyne incognita ku-greenhouse, singasebenzisa ukushisa okuphezulu ehlobo ukubulala ama-nematode amaningi.Ngesikhathi esifanayo, singakwazi futhi ukubola izinsalela zezitshalo i-Meloidogyne incognita encike kuzo ukuze ziphile emhlabathini.

Ngaphezu kwalokho, lapho inhlabathi isihlabathi, kufanele sithuthukise inhlabathi unyaka nonyaka, okungase futhi kunciphise ngempumelelo umonakalo we-Meloidogyne incognita.

5. Ukuphathwa kwenkundla

Singafaka Umquba obolile ensimini futhi sandise umanyolo we-phosphorus ne-potassium, ongathuthukisa ukumelana nezifo zezitshalo.Kufanele sikhumbule ukuthi akumele sisebenzise Umquba Ongakavuthwa, okuzokwenza kube kubi kakhulu ukwenzeka kwe-Meloidogyne incognita.

6. Ukwandisa ukusetshenziswa komanyolo webhayoloji osebenzayo futhi uqinise nokuphathwa kokutshala

Kudingeka sisebenzise umanyolo webhayoloji wokulawula i-nematode (isibonelo, oqukethe i-Bacillus thuringiensis, i-purple spore, njll.) ukuze kuthuthukiswe i-microbial flora yomhlabathi, ukuvimbela ngempumelelo ukuvela kwe-nematode, ukukhulisa ukukhula, nokunciphisa ukulimala kwe-Meloidogyne incognita.
