La I-poa enamandla Kuyindlela ye- izinhlobo zotshani ezithandwa kakhulu ngaphansi kwamagama ama-bulbous prairie ne-bulbous bluegrass; Iqhamuka eNyakatho Afrika nase-Eurasia, isakazeke njengohlobo olwethulwayo cishe emhlabeni jikelele, inokubonakala okukhulu eningizimu yeCanada kanye nase-United States. Ungathanda yini ukwazi okuningi ngaye? Uma kunjalo, ungayeki ukufunda.
Iqukethe isitshalo esingapheli, okuvame ukufika kubude obucishe bube ngama-30-60m futhi kwezinye izimo kuze kufike ku-90cm; Amaqabunga awo aqondile futhi mancane, anesisindo esiphakathi kuka-3-5mm ububanzi no-20cm ubude, futhi angaba rhabaxa noma apholishwe, kuhlangene ne-ligule engaba ukusuka emgodini onqunyiwe kuya koyindilinga, ovame ukuba nobude obuzungeze u-1-2mm.
Izici ze I-poa enamandla
Izimbali zayo zizalwa zinomumo oyindilinga kuma-panicles ubude bawo buphakathi kuka-10-20cm, futhi anezisekelo ezinamagatsha angaba ngu-3-5; ngenkathi ama-spikelets ayo eluhlaza futhi amile okweqanda, azungeze u-3-6mm ubude futhi anezimbali ezi-2-5.
Imvamisa yehlukaniswa yibo bobabili ama-rhizomes nezinyoka, kwakha utshani obukhulu; amahlumela awo: izinyoka nama-rhizomes, avela ikakhulukazi entwasahlobo, njengasekupheleni kwehlobo, zikhula ziqonde futhi zime, yize ekuqaleni kwentwasahlobo zivame ukuba yizikhukhula.
Ebusika bonke, kuzalwa amaqabunga amasha; kodwa-ke, ama-rhizomes amaningi ekugcineni aba ngamahlumela amanye ama-rhizomes angaphansi kwenhlabathi. Bangakwazi ukuphuma ngezikhathi ezahlukahlukene unyaka wonke, ngoba ngokuvamile, isikhathi sempilo yama-rhizomes ngawodwana siba ngaphezu kwezinkathi ezi-2 ezikhulayo, ngakho-ke isikhathi sabo sokuphila esiphelele kanye nesokukhishwa kwabo ukuphela akuvamisile ukufinyelela eminyakeni emibili.
Ukubhebhetheka
La I-poa enamandla kuvame ukusatshalaliswa ngezimbewu. Y Kumele kukhunjulwe ukuthi izilimo ezintsha azidingi ukukhanya kuphela, kepha nokunisela ngezikhathi ezithile (cishe izikhathi ezingama-2-3 nsuku zonke phakathi namasonto amabili okuqala). Lapho isitshalo sizelwe, kuzoncipha imvamisa yokuchelela.
Ukunakekelwa
Utshani obuncane kufanele busikwe noma nini lapho budlula u-5cm ukuphakama yokusika; futhi yize kubalulekile ukuthi ukugunda okulandelayo kwenziwe ngezikhathi ezithile, kubalulekile ukuthi kuqinisekiswe ukuthi akukho ngaphezu kwesigamu sensimbi ekhishwayo lapho kugundwa. Izidingo zabo ze-nitrogen zivame ukuphakama kakhulu unyaka wonke wokutshalwa futhi zehle eminyakeni elandelayo.
Ngalo mqondo, kufanele kwaziwe ukuthi la I-poa enamandla izophendula ekunikezelweni kwe-nitrogen cishe okungama-25-27kg / ha ngonyaka wokuqala, kepha kulondolozo okumele lunikezwe ngemuva konyaka wokuqala, okufanele kakhulu kuvame ukuba cishe ngama-90-130kg / ha. Kumele kuqashelwe ukuthi kulo lonke ihlobo, lesi sitshalo singakhula lapho kunikezwa inani elikhulu le-nitrogen encibilikayo noma ngokungaqinisekisi ukuyinisela ngokushesha ngemuva kokufakwa kwayo.
Izifo
Izifo eziyinhloko lesi sitshalo esivame ukubhekana nazo lapho sezikhulile ezindaweni eziguqukayo ngokuvamile ziyimpuphu, i-fusarium y isikhunta, ngaphezu kwalokho, kuyaziwa ngokuba uhlobo olunokuthambekela okukhulu kokuhlaselwa ama-russe kanye helminthosporiosis.
Sebenzisa
Kuvame ukusetshenziswa ngaphakathi kwezingadi namapaki, kanye nasezinkundleni zebhola. Ngendlela efanayo, singasho ukuthi ukusetshenziswa kwayo eSpain nakho kusanda kwenzeka, ngoba izinhlobo ebezikhona bezingezinhle, zinamahlamvu aminyene kakhulu futhi bezisebenzisa ukwamukela ithoni ephuzi engakhangi kangako ebusika.
Manje njengoba wazi okuningi ngalolu hlobo lokhula,ungathanda ukuyitshala engadini yakho? Uma kunjalo, ungakhohlwa ukubhekelela ukunakekelwa esikushilo ukugcina leli khambi lisesimweni esihle njalo.
