La Poa enobulunga Yi uninzi lweentlobo zengca ezithandwayo phantsi kwamagama i-bulbous prairie kunye ne-bulbous bluegrass; Ukuza okuvela eMantla e-Afrika nase-Eurasia, ixhaphake njengezilwanyana ezizisiweyo phantse kwihlabathi liphela, zinobukho obukhulu emazantsi eCanada naseMelika. Ngaba unomdla wokwazi ngakumbi ngaye? Ukuba kunjalo, musa ukuyeka ukufunda.
Iqukethe isityalo esingapheliyo, esihlala sifikelela kubude obumalunga ne-30-60m kwaye kwezinye iimeko ukuya kuthi ga kwi-90cm; Amagqabi ayo amelele kwaye acekeceke, aphakathi ko-3-5mm ububanzi kunye no-20cm ubude, kwaye angarhabaxa okanye agudiswe, kunye ne-ligule enokuthi isuswe kumbengo osikiweyo ukuya ku-rounded, oqhele ukuba nobude obunga-1-2mm.
Iimpawu ze Poa enobulunga
Iintyatyambo zayo zizalwa zinee-panicles ezicokisekileyo ubude bazo buphakathi kwe-10-20cm, kunye baneziseko ezinamasebe amalunga ne-3-5; Ngelixa ii-spikelets zayo ziluhlaza kwaye zimile okweqanda, zijikeleze i-3-6mm ubude kunye neentyatyambo ezi-2-5.
Ihlala yahlulwe zizo zombini iirhizomes kunye neenyoka, zenza ingca eshinyeneyo; amahlumelo ayo: iinyoka kunye neerhizomes, zibonakala ikakhulu entwasahlobo, kanye njengasekupheleni kwehlobo, Ukukhula nkqo kwaye kume nkqo, nangona ekuqaleni kwentwasahlobo bathanda ukuba recumbent ngakumbi.
Ebusika, amagqabi amatsha azalwa; Nangona kunjalo, uninzi lweerhizomes ekugqibeleni luba ngamahlumela ezinye iirhizomes ezingaphantsi komhlaba. Banokuphuma ngaphandle ngamaxesha ahlukeneyo unyaka wonke, Ngokubanzi, ixesha lokuphila kweerhizomes nganye zihlala zikhula ngaphezulu kwamaxesha ama-2 okukhula, ke ubomi babo bebonke, kunye nokukhululwa kwabo kwisiphelo, kuhlala kungafikeleli kwiminyaka emi-2.
Usasazeko
La Poa enobulunga idla ngokusasazwa ngembewu. Y Kufuneka kukhunjulwe ukuba izityalo ezitsha azifuni kukhanya kuphela, kodwa kwakhona ukunkcenkceshela ngamaxesha athile (malunga namaxesha ama-2-3 mihla le kwiiveki ezimbini zokuqala). Nje ukuba sizalwe isityalo, kuya kubakho ukunciphisa ukunkcenkceshela rhoqo.
Unonophelo
Ingca esencinci kufuneka isikwe nanini na xa idlula kwi-5cm ukuphakama yokusika; kwaye nangona kuyimfuneko ukuba ukucheba okulandelayo kwenziwe ngamaxesha athile, kubalulekile ukuba kuqinisekiswe ukuba akukho ngaphezulu kwesiqingatha sebala elisusiweyo xa kuchetywa. Iimfuno ze-nitrogen zihlala zithande ukuba phezulu kakhulu kunyaka wazo wokumiliselwa kunye nezantsi kwiminyaka elandelayo.
Ngale ndlela, kufanele kuqatshelwe ukuba la Poa enobulunga iyakuphendula kunikezelo lwe-nitrogen malunga ne-25-27kg / ha Kunyaka wokuqala, kodwa kulondolozo ekufuneka lubonelelwe emva konyaka wokuqala, olona lufanelekileyo luhlala malunga ne-90-130kg / ha. Kufuneka kuqatshelwe ukuba ehlotyeni lonke, lo mfuno ungakhula xa kunikwe isixa esikhulu senitrojeni enyibilikayo okanye ngokungaqinisekisi ukuyinkcenkceshela kwangoko emva kokufaka.
Izifo
Izifo eziphambili esi sityalo esihlala sisokola kuzo xa sikhule kwindawo yotshintsho zihlala zingumgubo, ifusarium y ukungunda, Ukongeza, yaziwa ngokuba uhlobo olunotyekelo olukhulu lokuhlaselwa zizo zombini irus kunye helminthosporiosis.
Sebenzisa
Ihlala isetyenziswa ngaphakathi kwiigadi kunye neepaki, kunye nangaphakathi kumabala ebhola ekhatywayo. Kwangokunjalo, sinokuthi ukusetyenziswa kwayo ngaphakathi eSpain nako kutsha nje, kuba iindidi ebezifumaneka bezikumgangatho ophantsi, zinamagqabi ashinyeneyo kakhulu kwaye zisetyenziselwa ukwamkela ithoni engathandekiyo emthubi ebusika.
Ngoku ukuba uyazi ngakumbi ngolu hlobo lokhula,ungathanda ukuyityala egadini yakho? Ukuba kunjalo, ungalibali ukuthatha inkathalo esele siyikhankanyile ukugcina le mifuno ikwimeko entle.
