Ama-Strawberries angenile esigabeni sokuqhakaza, futhi izinambuzane eziyinhloko kuma-strawberries-aphid, ama-thrips, izibungu zesicabucabu, njll nazo ziqala ukuhlasela. Ngenxa yokuthi ama-spider mite, ama-thrips, nama-aphid yizinambuzane ezincane, zicashe kakhulu futhi kunzima ukuzibona ekuqaleni. Nokho, azala ngokushesha futhi angabangela kalula izinhlekelele futhi abangele ukulahlekelwa okukhulu kwezomnotho. Ngakho-ke, kuyadingeka ukuqinisa inhlolovo yesimo sezinambuzane ukuze kutholakale ukutholakala kusenesikhathi nokuvimbela nokulawula kusenesikhathi.
Izimpawu zokulimala
1. Izintwala
Izinambuzane eziyinhloko ezilimaza ama-strawberry yizintwala zikakotini nezintwala zepentshisi eziluhlaza. Abantu abadala kanye nama-nymphs bahlangana ngaphansi kwamaqabunga ama-sitrobheli, amaqabunga ayisisekelo, nama-petioles, abamunca ijusi yama-sitrobheli kanye nokukhipha uju. Ngemva kokulimala kwamaphuzu okukhula kanye namaqabunga angumongo, amaqabunga ayagoqa futhi ayasonteka, okuthinta ukukhula okuvamile kwesitshalo.
2. Amathrips
Ngemva kokuba amaqabunga e-strawberry ewonakele, amaqabunga awonakele ayaphela futhi ashiye izimpawu zamazinyo. Amaqabunga aqala abonisa amachashaza amhlophe bese exhunywa emashidini. Lapho umonakalo unzima, amaqabunga aba mancane, ancipha, noma aphuzi, ome, futhi abune, okuthinta i-photosynthesis; ngesikhathi sokuqhakaza, amaqabunga awonakele. Ukulimala kungase kubangele ukuhlanekezela kwe-stamen, ukungazali kwembali, ukuguga kwe-petal, njll. Izinambuzane ezindala zingalimaza izithelo futhi zithinte ukubaluleka kwezomnotho kwezithelo. Ngaphezu kwalokho, ama-thrips angasakaza amagciwane ahlukahlukene futhi abangele ukulimala ekukhiqizeni ama-strawberry.
3. Inkanyezi
Uhlobo oluyinhloko lwe-spider mite olulimaza ama-strawberry yi-spider mite enamabala amabili. Isibungu esidala esisikazi sibomvu ngokumnyama namabala amnyama emaceleni omabili omzimba futhi simise okweqanda. Amaqanda e-Overwintering abomvu, kanti amaqanda angewona ama-overwintering awaphuzi ngokuphaphathekile. Izibungu ezincane zesizukulwane se-overwintering zibomvu, kanti izimbuzane ezincane zesizukulwane esingenayo i-overwintering ziphuzi. I-nymphae yesizukulwane se-overwintering ibomvu, futhi i-nymphae yesizukulwane esingena-overwintering iphuzi namabala amnyama ezinhlangothini zombili zomzimba. Izimbuzane ezindala, ezincane kanye ne-nymphal zimunca ubisi ngaphansi kwamaqabunga futhi zakhe ama-web. Esigabeni sokuqala, amabala e-chlorosis avela emaqabunga, futhi ezimeni ezinzima, amachashazi amhlophe ahlakazekile yonke indawo. Ezimweni ezimbi kakhulu, amaqabunga ayashisa futhi awe, okubangela ukuguga kwezitshalo ngaphambi kwesikhathi.
Imithetho yezehlakalo
1. Izintwala
Ama-aphid ngokuvamile ahamba emaqabunga amancane, ama-petioles, namaqabunga angaphansi ukuze amunce ubisi futhi akhiphe amazolo ukuze angcolise amaqabunga. Ngesikhathi esifanayo, ama-aphid asakaza amagciwane futhi alulaze izithombo.
2. Amathrips
Isimo sezulu esifudumele, esomile siyakuvumela lokhu. Kwenzeka njalo ngonyaka ku-greenhouse yelanga kanye nezinhlobo kanye nama-overwinters lapho, ngokuvamile izizukulwane eziyi-15-20 / ngonyaka; kwenzeka ku-greenhouse entwasahlobo nasekwindla kuze kufike ukuvuna. Ama-Nymphs kanye nabantu abadala bavame ukucasha phakathi kwezimbali namacembe agqagqene, futhi acashe kakhulu. Kunzima ukuthi ama-insecticide ajwayelekile axhumane ngqo futhi abulale izinambuzane.
3. Inkanyezi
Izimbuzane ezisencane kanye nama-nymphs asesigabeni sokuqala awasebenzi kakhulu, kanti ama-nymph asesiteji sakamuva ayasebenza futhi anemiminzi futhi anomkhuba wokukhuphukela phezulu. Ithinta amaqabunga aphansi kuqala bese isakazeka phezulu. Izinga lokushisa eliphezulu kanye nesomiso kulungele kakhulu ukwenzeka kwezibungu zesicabucabu, futhi izimo ezinomswakama ophezulu wesikhathi eside zenza kube nzima ukuphila.
Ubuchwepheshe Bokuvimbela Nokulawula
1. Izintwala
(1) Izinyathelo zezolimo:susa ngokushesha amaqabunga ama-sitrobheli amadala nanesifo futhi usule ukhula ezungeze indawo ebamba ukushisa.
(2) Ukuvimbela nokulawula ngokomzimba:Beka amanethi angangeni ezinambuzaneni ezindaweni zokungenisa umoya; misa amabhodi aphuzi ukuze acuphe futhi awabulale ku-greenhouse. Azosetshenziswa kusukela esikhathini sokutshala. I-greenhouse ngayinye isebenzisa izingcezu eziyi-10-20, futhi ukuphakama okulengayo kuphakeme kancane kunezitshalo ze-sitrobheli ngo-10-20 cm. Bamba ama-aphid anamaphiko bese uwashintsha njalo.
(3) Ukulawulwa kwezinto eziphilayo:Ezigabeni zokuqala zokuvela kwe-aphid, ama-ladybugs akhululwa ensimini, futhi ama-calories angu-100 ihektha ngalinye (amaqanda angu-20 ngekhadi ngalinye) akhululwa ukuze abulale ama-aphid. Naka ukuvikela izitha zemvelo ezifana nama-lacewings, ama-hoverflies, neminyovu ye-aphid braconid.
(4) Ukulawula amakhemikhali:Ungasebenzisa ama-25% ama-thiamethoxam ahlakazeka emanzini izikhathi ezingu-3000-5000 njengoketshezi, 3% i-acetamiprid EC 1500 izikhathi njengoketshezi, kanye no-1.8% i-abamectin EC izikhathi ezingu-1000-1500 njengoketshezi. Naka ukushintshashintsha kwemithi. Naka isikhawu sokuphepha kwezibulala-zinambuzane ukuze ugweme ukukhula kokumelana nezibulala-zinambuzane kanye ne-phytotoxicity. (Qaphela: Ukuze ulawule isifutho, gwema isikhathi sokuqhakaza kwama-strawberry, futhi ukhiphe izinyosi eshede lapho ufaka izibulala-zinambuzane.)
2. Amathrips
(1) Ukuvimbela nokulawula ezolimo:Sula ukhula emasimini emifino nasezindaweni ezizungezile ukuze unciphise isizinda sabantu sezinambuzane ezihlala isikhathi eside ebusika. Kunzima kakhulu ngesikhathi sesomiso, ngakho-ke umonakalo ungancishiswa ngokuqinisekisa ukuthi izitshalo ziniselwa kahle.
(2) Ukulawula ngokomzimba:Izicupho zezinambuzane eziluhlaza noma eziphuzi zisetshenziselwa ukubamba ama-thrips, okusebenza ngempumelelo. Lenga izingcezu ezingama-20-30 ihektare ngalinye, futhi unqenqema olungezansi lwepuleti lombala kufanele libe ngu-15-20cm ukusuka phezulu kwesitshalo, futhi ande njengoba isitshalo sikhula.
(3) Ukulawulwa kwezinto eziphilayo:Inani lama-thrips lingalawuleka ngempumelelo ngokusebenzisa izitha zemvelo zezibungu ezidla ezinye. Uma ama-thrips etholakala ku-greenhouse, ukukhululwa ngesikhathi kwezibungu ze-Amblysei ezingu-20,000 noma izibungu ezintsha ze-cucumber/acre, kanye ngenyanga, kungalawula ngempumelelo umonakalo. Izibulala-zinambuzane azivunyelwe ukuthi zisetshenziswe ezinsukwini ezingu-7 ngaphambi nangesikhathi sokukhululwa.
(4) Ukulawula amakhemikhali:Uma umthwalo wezinambuzane uphansi, sebenzisa u-2% emamectin EC 20-30 g/mu kanye no-1.8% abamectin EC 60 ml/mu. Uma izinambuzane zithwala kanzima, sebenzisa u-6% we-spinosad 20 ml/acre ukuchela ngamahlamvu. Lapho sisebenzisa izibulala-zinambuzane, okokuqala, kufanele sinake okunye ukusetshenziswa kwezibulala-zinambuzane ezihlukene ukuze zenze buthaka ukumelana kwazo. Okwesibili, kumelwe sinake sishaye izibulala-zinambuzane hhayi kuphela izitshalo kodwa futhi emhlabathini lapho sishaye, ngoba ezinye izibungu ezivuthiwe pupate emhlabathini. (I-Amamectin ne-abamectin zinobuthi ezinyosini. Uma ufutha ukuze uzilawule, gwema isikhathi sokuqhakaza kwama-strawberry, futhi ukhiphe izinyosi eshede lapho ufaka izibulala-zinambuzane; i-spinosad ayinabo ubuthi ezinyosini.)
3. Inkanyezi
(1) Ukuvimbela nokulawula ezolimo:susa ukhula ensimini futhi uqede umthombo wezinambuzane ze-overwintering; ngokushesha ngqongqoza amaqabunga ezinambuzane zeqabunga elidala futhi uwakhiphe ensimini ukuze abhujiswe endaweni eyodwa.
(2) Ukulawulwa kwezinto eziphilayo:Sebenzisa izitha zemvelo ukuze ulawule inani lezibungu ezibomvu ezigabeni zokuqala zokuvela, futhi ukhulule i-Amblyseidia barbari ensimini, nabantu abangu-50-150/square meter, noma izibungu zePhytoseiid ezinabantu abangu-3-6/square meter.
(3) Ukuvimbela nokulawula amakhemikhali:Ekusetshenzisweni kokuqala, ukumiswa kwe-diphenazine okungu-43% izikhathi ezingu-2000-3000 kanye no-1.8% we-abamectin izikhathi ezingu-2000-3000 kungasetshenziswa ukufutha. Lawula kanye njalo ezinsukwini eziyi-7. Umphumela wokunye ukusebenzisa amakhemikhali uzoba ngcono. kuhle. (I-Diphenyl hydrazine ne-abamectin ziwubuthi ezinyosini. Uma ufutha ukuze uzilawule, gwema isikhathi sokuqhakaza kwama-strawberry, futhi ukhiphe izinyosi eshede lapho ufaka izibulala-zinambuzane.)
