Makhalidwe Abwino ndi Quackgrass

Zomwe zimakhala zosaoneka bwino komanso zosaoneka bwino zimawoneka mofanana, koma zimasiyana kwambiri. Chifukwa chimodzi, quackgrass ndi nyengo yozizira yomwe imatha nthawi zonse (onetsetsani kuti imatha kukula m'mapiri aatali) kumene malo oundana ndi nyengo yotentha. Iwo ali ndi njira zosiyana zofalitsira ndipo njira zothetsera nthawi yayitali zothetseratu ndizosiyana. Zothetsera nthawi yaitali zowonongeka ndi zowonjezereka, komabe ziri zofanana kwambiri.

Malinga ndi database ya USDA Plants, quackgrass ikukula paliponse ku North America-kuchokera ku Gulf of Mexico kupita ku Nyanja ya Arctic - kupatulapo malo ochepa a kumwera. Ndi udzu wolimba wosatha , womwe umatanthauza kuti udzabweranso chaka ndi chaka. Ndipotu, imakhala yobiriwira chaka chonse m'madera ena. Siwo chomera chobadwira. Amabereka kuchokera ku mbewu zonse komanso pansi pa nthaka (rhizomes) yomwe imamera pansi mamita asanu ndi limodzi.

Inde, opha njoka zamitundu yosiyanasiyana adzabwezeretsa-monga momwe zidzabwerera kutchetchera kumtunda wotsika kwambiri mu kasupe. Pazochitika zonsezi, nthawi ndi kubwereza ndizo zonse. Zakudya zam'madzi zimadalira kwambiri chakudya chomwe chimakhala m'midzi yake. Kumayambiriro kwa kasupe mumagwedeza pansi ndipo / kapena kutsanulira masamba, pang'ono ndi pang'ono kumatha kumanga chakudya m'magazi. Yembekezani kupopera kapena kutchera mobwerezabwereza kuti mizu izikhala mu njala.

Kuwonjezera pa kumenyana ndi quackgrass, komatu kumbukirani kulimbikitsa udzu wokoma udzu. Pali mwayi waukulu kuti udzu udzuke phokoso. Simungathe kuchotsa zonsezi, koma zidzakhala zochepa kwambiri.

Zindikirani: Pansi pa machitidwe osiyanasiyana otchulidwa, quackgrass angatchulidwe monga Elymus repens, Agropyron repens kapena Elytrigia repens.

Makhalidwe

Nkhono ndi chaka chomwe chimakula kuchokera ku mbewu m'nyengo yotentha. Oyang'ana kumpoto samaziwona mpaka May.

Dzina lakuti "crabgrass" kwenikweni ndi ambulera kwa mitundu yambiri yofanana. Mndandanda wa zomera za USDA umatchula mitundu yoposa 60 mu mtundu wa Digitaria ndipo amakhala m'madera onse a US ndi kumwera kwa Canada. Ena ndi mbadwa, ena amayamba. Zomwe zimadera nkhaŵa kwambiri pa udzu ndizosiyana ndi zozizira zomwe zimakhala zosalala ( Digitaria ischaemum ) ndi zopweteka zamoto ( Digitaria sanguinalis ).

Kukonzekera kwachinyengo kumakhala kosavuta, kutenga malo opanda kanthu kumene kulibe kanthu kena kamene kamakula. Sizitsutsana ndi chinyezi, pH, kapena kubala, choncho zimadzipereka kumene udzu uli wofooka. Kumpoto, nkhalango imakhala ndi msipu wobiriwira pamene udzu wozizira umalimbana ndi dzuwa ndi chilala.

Mbalame imamwalira m'nyengo yozizira, imasiya malo obiriwira otchinga mu udzu. Nkhono zimabereka kuchokera ku mbeu chaka chilichonse. Chomera chilichonse chimapanga mbewu zambirimbiri ndipo mbewu zimatha kukhala zothandiza kwa zaka zambiri.

Kukonzekera kwachinyengo kwachititsa kuti anthu onse asokonezeke, omwe akupha anthu oyamba . Ngakhale mapulogalamu ofotokoza mankhwalawa ali othandiza, iwo alibe zovuta zazikulu. Zina zisanachitike zimakhudza mbewu zonse za udzu kwa milungu isanu ndi iwiri itatha. Choncho, mbewu zabwino zimaletsedwa pamodzi ndi crabgrass.

Mbewu ya gluten imayamba kugwiritsidwa ntchito monga gawo la mapulogalamu a udzu. Sichimaletsa mbewu za udzu, koma zimakhala zochepa kwambiri pazomwe zimapangidwira.

Anthu ophera udzu amatha kusamba, makamaka akamagwiritsa ntchito mbeu isanakwane . Pali zida zonse zopangira mankhwala omwe amapanga mankhwala osokoneza bongo.

Njira imodzi yowonongolera nkhwangwa ndikutenga chikhomo mu August kapena September pamene zomera zimapita ku mbewu. Izi zidzasungira mbewu zowonongeka kuchokera ku udzu.

Kuteteza Udzu wa Udzu Ndiwo Mphatso Yabwino Kwambiri

Zomwe zimagwiritsidwa ntchito ndi zitsamba zomwe zimakhala bwino pamene udzu ndi wofooka kapena ulibe. Choncho, mankhwala abwino ndi othandizira kwambiri kwa ena mwa namsongole. Ndikofunika kwambiri kulimbikitsa mizu yakuya chifukwa ichi ndi chonchi choteteza chitetezo cha chilala. Chilala chimapanga malo otsekemera mu nkhono kumene nsomba zam'madzi, quackgrass, ndi namsongole zambiri zimatha kupambana.

Kusamalira bwino udzu kumayamba nthawi zonse ndi kuyesa nthaka . Onetsetsani kuti mufunse malipiro a zinthu zakutchire ndi malipoti anu oyesa nthaka, ngakhale atakhala ndi zina zambiri kuti atenge lipoti ili. Mayeso angapangitse laimu kapena sulfure kuti afike pH yolondola (6.5 mpaka 7.2). Ikhoza kulangiza kompositi kuti imange zinthu zofunikira. Pamapeto pake, malipoti oyesa nthaka amasonyeza kuti ali ndi nayitrogeni, phosphorous, ndi potaziyamu yoyenera.
