Mmene Mungaphere Crabgrass

Kodi ukudziwa chomwe chiwongoladzanja chikuwonekera ? Digitaria (dzina la zomera la zomera) ndi nyengo yowonjezera pachaka ; imabereka ndi mbewu. Nthawi zambiri anthu amandifunsa momwe ndingachiphe. Yankho lalifupi ndi lakuti: kugwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda pa nthawi yoyenera ndi njira yabwino yothetsera udzu uno.

Preemergent Herbicides Popha Crabgrass: Nthawi Yopempha

Kuti tichotse zovuta, zimathandiza kudziwa moyo wake . Pamene kasupe nthaka kutentha (pozama masentimita 2-3) ifika madigiri 55 mpaka 60 Fahrenheit, mbewu yoyamba idzaphuka (pokhapokha ngati mutayimitsa panthawiyi pogwiritsa ntchito mankhwala oyambirira a herbicide!).

Kuyambira pakati pa chilimwe kugwa, mbewu zimapangidwa. Zomera, zokha (koma osati mbewu) zimaphedwa ndi chisanu mu autumn.

Zakudya zam'madzi zowonjezera zam'mimba (inu mumamvaponso mawu akuti "crabgrass preventer") amabwera mu mawonekedwe a granular kapena a madzi ndikupha mbande zachitsamba pamene zikuphukira. Ganizilani za mankhwala ophera tizilombo toyambitsa matenda monga kupanga chivundikiro chosaoneka padziko lonse lapansi chomwe chimasiya kuphulika kumeneku kukufa. Chithunzi chotetezera ichi chidzakhala ngati chikumbutso choti musamachite mchitidwe wa aeration pazitsamba mutagwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda, chifukwa kuchita izi kungangotulutsa chishango. Udzu wokhala ndi mpweya wabwino, m'malo mwake.

Monga momwe dzina lawo limasonyezera, mankhwala oyambitsa matenda a herbicides amapha anyaniwa pa nthawi yake : mbande zake zisanatuluke . Kuti zinthu zitheke pochotseratu chiwonongeko, njirayi ndi yofunika kwambiri. Ikani mankhwala oyambirira a herbicides musanayambe kumera, koma osati patali kwambiri. Kumera kumera kumaphatikizana ndi kukula kwa tchire la lilac .

Choncho mawu akale (chitsanzo cha "phenology" kuti atsogolere zolemba za ntchito ) kuti mankhwala odyetseratu mankhwala oyambirira azigwiritsidwa ntchito nthawi ina pakati pa nthawi ya tosythia tchire (yomwe imatsogolera malala ndi milungu ingapo) kuyima ndikuyamba kutentha kwa lilac ikufalikira.

Mitundu ya Mankhwala Ochepetsa Mankhwala Osakaniza

Pali mitundu yambiri ya mankhwala ophera tizilombo toyambitsa matenda.

"Zamsongole ndi zakudya" zimakhala ndi mankhwala othandizira kwambiri, ngakhale ena akukayikira ngati ndondomeko yawo ndi yamphamvu kuti ikhale yogwira mtima. Ndimaganizira za mankhwala a herbicide awiri oyambirira: Dimension ndi Tupersan.

Dothi (gawo lothandizira, dithiopyr) liri lotetezeka kugwiritsira ntchito udzu wambiri (fufuzani tsamba yoyamba) ndipo imapereka chithandizo chokhalitsa - chofunika kwambiri popeza palibe mbeu yonse yomwe imamera. Potero Mbande idzapha pambuyo pake-kumera mofulumira, nayenso. Mdima umasonyezanso kuti ndiwotheka ngati mankhwala otsekemera.

Tupersan (chogwiritsidwa ntchito, siduron) chiyenera kutchulidwa chifukwa, mosiyana ndi mankhwala enaake oyamba, sizingapangitse mbewu zouma zouma (zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala pamodzi ndi feteleza zoyambitsa zitsamba). Mtundu uwu wa Tupersan umapangitsa kuti iwo omwe ayamba udzu watsopano kuchokera ku mbewu . Koma bwanji ngati mukugwiritsa ntchito chiopsezo chotchedwa crabgrass ena osati a Tupersan komanso kuyambanso udzu watsopano? Muli ndi njira ziwiri:

1. Pa udzu watsopano, dikirani mpaka katatu mowings (kapena miyezi itatu, kuti mukhale otetezeka) musanagwiritse ntchito mankhwala ophera mchere.
2. Kapena musinthe kayendetsedwe ka ntchito zanu: kutanthauza kugwiritsa ntchito mankhwala oyambirira a herbicide poyamba, dikirani miyezi itatu, ndikubzala mbewu zanu za udzu.

Kugwiritsira ntchito mankhwala ophera tizilombo toyambitsa matenda chifukwa chopha Crabgrass: DOs ndi DON'Ts

• Kodi :

1. Kuthirira pambuyo pake: madzi amachititsa preemergent herbicides. Pa chifukwa chomwecho, nthawi yabwino yopanga polojekitiyi ndi pamene mvula yowonongeka ikuyembekezeredwa tsiku lotsatira.
2. Bwerezerani kachilombo koyambitsa mankhwala, ngati mukukayikira za mankhwala anu. Chifukwa chakuti mbande zazitsamba sizitha kumera nthawi imodzi, kubwezeretsa kachiwiri kumatha kupha mbewu zina zomwe zimamera pambuyo pake.
3. Tsatirani malemba anu ndikugwiritsa ntchito mlingo woyenera. Yerengani udzu ndipo muyang'ane mosamala wanu.

• Musati :

1. Dulani kapena aerate udzu mutagwiritsa ntchito preemergent herbicides.
2. Gwiritsani ntchito mankhwala othandizira kuti asatengere mankhwala atsopano.

Kodi Ndingatani Ngati Udzu Wanga Umadzaza ndi Ziphuphu M'nyengo Yam'nyengo?

Malangizo omwe ali pamwambawa akuthandizira owerenga poganizira za kupewa, zomwe ziyenera kuchitika pamene mbewu zatsala pang'ono kumera masika.

Koma bwanji ngati mukuwerenga nkhaniyi m'chilimwe, mutatha kuzindikira kuti mumatchire mumatope? Kwa inu, ndichedwa kwambiri kuti mugwiritse ntchito chiopsezo cha crabgrass.

Mwamwayi, muli ndi mivi yoposera imodzi mumayesero anu kuti muphe kupha. Mwachitsanzo, palinso mankhwala ophera tizilombo toyambitsa matenda omwe amafalikira chifukwa chofalikira (mwachitsanzo, Acclaim Extra). Izi ndizimene muyenera kuganizira ngati mukulimbana ndi udzu wolimba mu chilimwe .

Komabe, mankhwala ophera tizilombo toyambitsa matenda amayamba kukhala othandiza popha achinyamata. Chifukwa zomera zazing'onozi ndizochepa, zimakhala zovuta kuziwona mu udzu. Muyenera kukhala tcheru pakuwazindikira ndikuyamba kugwiritsa ntchito mankhwala ophera tizilombo. Ndicho chifukwa chake herbicide yotereyi sichitha kugwiritsidwa ntchito mosavuta kusiyana ndi mankhwala ophera mankhwala oyambitsa matenda ophera tizilombo toyambitsa matenda. Ndimapereka zitsanzo za mankhwala ophera tizilombo toyambitsa matenda, komanso momwe angagwiritsire ntchito mankhwalawa, m'nkhani yanga komanso ndondomeko za momwe mungagwiritsire ntchito mankhwalawa, m'nkhani yanga yonena za opha nsomba zabwino kwambiri .

Organic Control:

"Koma kodi ndikufunikiradi mankhwala omwe amachititsa kuti zisawonongeke?" mumapempha. Yankho lake ndi lakuti, Ayi. Ngakhale njira yabwino kwambiri yowonongera zowonongeka zimakhala ndi mankhwala oyambitsa matenda a herbicides, njira yabwino yothetsera vutoli ndiyo kukhala ndi udzu wathanzi. Nazi njira zina zolimbikitsira thanzi la lawn - phindu la nkhanza:

• Manyowa (kompositi ndi yabwino) kwambiri m'dzinja kuposa masika. Pofika m'dzinja, chisanu chidzafa kale.
• Musalole mabala opanda kanthu kuti asawululidwe kwa nthawi yayitali, ngati zida zowonongeka zidzakhazikika. Pakugwa, lembani malo omwe mulibe malo omwe mukuwonekera .
• Mukamwetsa udzu , madzi mozama komanso mobwerezabwereza. Udzu ndi udzu wosakhwima kwambiri; Nthaŵi zambiri kuthirira madzi osasinthasintha kumakhala m'manja mwawo.
• Chimodzi mwa zothandiza kwambiri pakutchetcha udzu zomwe ndingathe kupereka monga zokhudzana ndi udzu ndi "kutchetcha pamwamba." Izi zikutanthauza kusiya udzu pamtunda wa 2 1/2 "-3". Kuchita zimenezi kumathandiza kuti udzu usunge " udzu wokhawokha" bwino, wotsutsa mbewu zowala zomwe amafunikira kuti zizitha kumera.

Mfundo Zotsiriza pa Crabgrass Control

Chomera chachikulu cha "udzu ndi chakudya" chiri chimanga cha gluten . Chomera cham'mimba cham'mimba, chimanga chamtundu chidzalepheretsa kumera , pamene mukufungira udzu wanu .

Musaiwale kupalira kwabwino kokalamba monga njira yowonongeka. Kusokera manja pang'ono zazing'onoting'ono zisanayambe kupita kumbewu zimapanga tanthauzo lalikulu. Nthawi imodzi yopezera chitetezo ndi yofunika pounds la mankhwala, ndipo njira yopezera imeneyi ili ndi phindu lina la kukhala organic. Pofuna kusamalitsa mbeu, sungani chitsamba choyamba (namsongole amangozizira mosavuta ku nthaka yonyowa).

Ngati mwasankha kugwiritsa ntchito mankhwala ophera tizilombo ku udzu wanu, musaiwale kuti mukugwira mankhwala omwe angathe kuwononga thanzi lanu. Kuti muteteze nokha, valani malaya atsopano, mathalauza, magolovesi, ndi magalasi oteteza. Onani nkhani yanga yowonjezera kuti mupeze zambiri pazomwe mungateteze pabwalo .
