Strawberries tau nkag mus rau theem paj, thiab cov kab tsuag tseem ceeb ntawm strawberries-aphids, thrips, kab laug sab mites, thiab lwm yam kuj tseem pib tua. Vim hais tias kab laug sab mites, thrips, thiab aphids yog cov kab me me, lawv tau zais heev thiab nyuaj rau kev tshawb pom nyob rau theem pib. Txawm li cas los xij, lawv rov tsim dua sai sai thiab tuaj yeem ua rau muaj kev puas tsuaj loj thiab ua rau muaj kev puas tsuaj loj. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev soj ntsuam kab mob kom ua tiav kev tshawb pom ntxov thiab kev tiv thaiv ntxov thiab kev tswj xyuas.
Cov tsos mob ntawm kev puas tsuaj
1. Aphids
Lub ntsiab aphids uas puas strawberries yog paj rwb aphids thiab ntsuab peach aphids. Cov neeg laus thiab nymphs pawg nyob rau hauv qab ntawm strawberry nplooj, core nplooj, thiab petioles, nqus strawberry kua txiv thiab secreting honeydew. Tom qab cov ntsiab lus loj hlob thiab cov nplooj tseem ceeb raug puas ntsoog, nplooj curl thiab twist, cuam tshuam rau kev loj hlob ntawm cov nroj tsuag.
2. Thrips
Tom qab cov nplooj strawberry puas lawm, cov nplooj puas ploj mus thiab tawm ntawm cov hniav. Cov nplooj pib qhia cov pob dawb thiab tom qab ntawd txuas rau hauv nplooj ntawv. Thaum qhov kev puas tsuaj loj heev, cov nplooj ua me me, ntsws, lossis txawm daj, qhuav, thiab wither, cuam tshuam rau photosynthesis; Thaum lub sij hawm flowering lub sij hawm, nplooj yog puas. Kev puas tsuaj tuaj yeem ua rau stamens distortion, paj sterility, petal discoloration, thiab lwm yam. Cov kab laus tuaj yeem ua rau cov txiv hmab txiv ntoo puas thiab cuam tshuam rau kev lag luam ntawm cov txiv hmab txiv ntoo. Tsis tas li ntawd, thrips tuaj yeem kis tau ntau yam kab mob thiab ua rau muaj kev puas tsuaj rau strawberry ntau lawm.

Lub ntsiab hom kab laug sab mite uas puas strawberries yog ob-spotted kab laug sab mite. Cov poj niam laus mite yog tsaus liab nrog cov pob dub ntawm ob sab ntawm lub cev thiab yog oval nyob rau hauv cov duab. Overwintering qe yog liab, thaum lub qe tsis-overwintering yog daj daj. Cov tub ntxhais hluas mites ntawm overwintering tiam yog xim liab, thaum cov hluas mites ntawm cov tsis-overwintering tiam yog daj. Cov nymphae ntawm lub caij ntuj no overwintering yog xim liab, thiab cov nymphae ntawm lub caij ntuj no tsis overwintering yog daj nrog dub me ntsis ntawm ob sab ntawm lub cev. Cov neeg laus, cov hluas thiab nymphal mites nqus cov kua txiv hmab txiv ntoo ntawm cov nplooj hauv qab thiab tsim cov webs. Nyob rau theem pib, cov pob txha chlorosis tshwm sim ntawm nplooj, thiab hauv qhov xwm txheej hnyav, cov dots dawb tau tawg mus thoob plaws. Hauv qhov xwm txheej hnyav, cov nplooj scorch thiab poob tawm, ua rau cov nroj tsuag ntxov ntxov.
Cov cai tshwm sim
1. Aphids
Aphids feem ntau txav mus los ntawm cov nplooj me, petioles, thiab nplooj hauv qab kom nqus cov kua qaub thiab tso cov honeydew kom paug cov nplooj. Nyob rau tib lub sijhawm, aphids kis kab mob thiab degrade seedlings.
2. Thrips
Cov huab cua sov, qhuav nyiam qhov no. Nws tshwm sim txhua xyoo nyob rau hauv lub hnub ci tsev cog khoom thiab yug me nyuam thiab overwinters muaj, feem ntau 15-20 tiam / xyoo; nws tshwm sim nyob rau hauv lub tsev xog paj nyob rau hauv lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg mus txog rau thaum sau. Nymphs thiab cov neeg laus feem ntau lurk nyob rau hauv nruab nrab ntawm paj thiab overlapping petals, thiab yog heev zais. Nws yog qhov nyuaj rau cov tshuaj tua kab dav dav kom tiv tauj ncaj qha thiab tua cov kab.
3. Starscream
Cov mites hluas thiab cov nymphs thaum ntxov tsis muaj zog heev, thaum lub sij hawm lig nymphs yog nquag thiab gluttonous thiab muaj tus cwj pwm ntawm nce toj. Nws cuam tshuam cov nplooj qis ua ntej thiab tom qab ntawd kis mus rau sab saud. Qhov kub thiab txias yog qhov zoo tshaj plaws rau qhov tshwm sim ntawm kab laug sab mites, thiab cov av noo mus ntev ua rau nws nyuaj rau kev ciaj sia.
Kev Tiv Thaiv thiab Tswj Technology
1. Aphids
(1) Kev ntsuas kev ua liaj ua teb:Tam sim ntawd tshem tawm cov laus thiab cov kab mob strawberry nplooj thiab tshem tawm cov nroj tsuag nyob ib ncig ntawm lub tsev xog paj.
(2) Kev tiv thaiv thiab kev tswj lub cev:Teeb tsa kab-pov thawj nets hauv qhov chaw ua pa; teeb tsa cov laug cam daj kom ntxiab thiab tua lawv hauv tsev cog khoom. Lawv yuav siv tau los ntawm lub sij hawm cog. Txhua lub tsev cog khoom siv 10-20 daim, thiab dai qhov siab me ntsis siab dua li cov nroj tsuag strawberry los ntawm 10-20 cm. Trap winged aphids thiab hloov lawv tsis tu ncua.
(3) Biological tswj:Nyob rau theem pib ntawm aphid tshwm sim, ladybugs raug tso tawm hauv thaj teb, thiab 100 calories ib acre (20 qe ib daim npav) raug tso tawm los tua aphids. Ua tib zoo saib xyuas cov yeeb ncuab ntuj xws li lacewings, hoverflies, thiab aphid braconid wasps.
(4) Tshuaj tswj:Koj tuaj yeem siv 25% thiamethoxam dej-dispersible granules 3000-5000 zaug ua kua, 3% acetamiprid EC 1500 zaug ua kua, thiab 1.8% abamectin EC 1000-1500 zaug ua kua. Ua tib zoo saib xyuas kev hloov tshuaj. Ua tib zoo saib xyuas qhov kev nyab xeeb ntawm cov tshuaj tua kab kom tsis txhob muaj kev txhim kho cov tshuaj tua kab thiab phytotoxicity. (Faj seeb: Rau kev tswj cov tshuaj tsuag, zam lub sij hawm strawberry flowering, thiab txav muv tawm ntawm lub tsev thaum siv tshuaj tua kab.)
2. Thrips
(1) Kev tiv thaiv kev ua liaj ua teb:Tshem cov nroj tsuag hauv thaj chaw zaub thiab thaj chaw ib puag ncig kom txo cov pejxeem hauv paus ntawm cov kab overwintering. Nws yog qhov hnyav dua thaum lub caij ntuj qhuav, yog li qhov kev puas tsuaj tuaj yeem txo los ntawm kev ua kom cov nroj tsuag zoo irrigated.
(2) Kev tswj lub cev:Blue los yog daj kab ntxiab yog siv los ntxiab thrips, uas zoo dua. Dai 20-30 pieces ib evkawj, thiab qis ntug ntawm cov xim phaj yuav tsum yog 15-20cm los ntawm sab saum toj ntawm cov nroj tsuag, thiab nce raws li cov qoob loo loj hlob.
(3) Biological tswj:Tus naj npawb ntawm thrips tuaj yeem tswj tau zoo los ntawm kev siv cov yeeb ncuab ntuj tsim los ntawm cov mites. Yog tias thrips pom nyob rau hauv lub tsev xog paj, tso tawm raws sijhawm ntawm 20,000 Amblysei mites lossis tshiab dib mites / acre, ib hlis ib zaug, tuaj yeem tswj tau qhov kev puas tsuaj. Cov tshuaj tua kab tsis raug tso cai siv 7 hnub ua ntej thiab thaum lub sijhawm tso tawm.
(4) Tshuaj tswj:Thaum cov kab load tsawg, siv 2% emamectin EC 20-30 g / mu thiab 1.8% abamectin EC 60 ml / mu. Thaum cov kab mob hnyav heev, siv 6% spinosad 20 ml / acre rau foliar txau. Thaum siv tshuaj tua kab, ua ntej, peb yuav tsum tau them sai sai rau kev siv cov tshuaj tua kab sib txawv kom lawv tsis muaj zog. Qhov thib ob, peb yuav tsum tau them sai sai rau kev txau tshuaj tua kab tsis yog ntawm cov nroj tsuag nkaus xwb tab sis kuj hauv av thaum txau, vim tias qee cov kab mob loj hlob pupate hauv av. (Amamectin thiab abamectin yog tshuaj lom rau muv. Thaum txau rau kev tswj hwm, zam lub sijhawm paj ntawm strawberry, thiab txav muv tawm ntawm lub tsev thaum siv tshuaj tua kab; spinosad tsis lom rau muv.)
3. Starscream
(1) Kev tiv thaiv kev ua liaj ua teb:tshem tawm cov nroj tsuag hauv thaj teb thiab tshem tawm qhov chaw ntawm cov kab overwintering; tam sim ntawd khob tawm cov kab laug sab qis nplooj thiab coj lawv tawm ntawm qhov chaw rau kev puas tsuaj.
(2) Biological tswj:Siv cov yeeb ncuab ntuj los tswj cov pej xeem ntawm kab laug sab mites thaum ntxov ntawm qhov tshwm sim, thiab tso Amblyseidia barbari hauv thaj teb, nrog 50-150 tus neeg / square meter, lossis Phytoseiid mites nrog 3-6 tus neeg / square meter.
(3) Tshuaj tiv thaiv thiab tswj:Rau kev siv thawj zaug, 43% diphenazine ncua kev kawm 2000-3000 zaug thiab 1.8% abamectin 2000-3000 zaug tuaj yeem siv rau kev txau. Tswj ib zaug txhua 7 hnub. Cov nyhuv ntawm kev siv tshuaj sib txawv yuav zoo dua. zoo. (Diphenyl hydrazine thiab abamectin yog tshuaj lom rau muv. Thaum txau rau kev tswj, zam lub caij nplooj ntoo hlav, thiab txav muv tawm ntawm lub tsev thaum siv tshuaj tua kab.)
