Azolla filiculoides inowanzozivikanwa se mosikito fern uye / kana mvura fern, Ndicho fern yemvura iyo inozivikanwa nekuve huswa hwegore hwehukuru hwakakura, huri mukati mevanhu hune hunyanzvi hwekukura kufukidza nzvimbo hombe dzinogadzira mune dzimwe nguva, inoenderera yakatenderera pamusoro pemvura mumadhaka, madhibhoni uye kunyangwe, munzvimbo dzemumvura. , ndosaka ichionekwa se dziva uye chirimwa che aquarium.
Nekudaro, nekuda kwekumhanyisa kwainokura nako, pamwe nemhedzisiro yainogadzira pane nharaunda, ndizvo yakarongedzwa semhando yemiti isingasviki uye nehasha mukati menyika dzinoverengeka, Spain iri imwe yadzo.
Zviratidzo
Ichi chikonzero kuiswa kweAzolla filiculoides mune yepakati kwakarambidzwa chizvarwa chenyika, nenzira imwechete nekutengeserana kwayo, kutakura uye / kana kutora. Izvo zvinokonzerwa nekuti chikamu chikuru cheshambadziro dzinoitika mukati mepakati chinoitwa netsaona.
Icho chirimwa chinoberekerwa kuAmerica, kunyanya nzvimbo dzayo dzakadzikama; ine saizi iyo denderedzwa 2,5-10cm uye ine mashizha akaita mativi matatu ayo mavanogona kuramba vachiyangarara pamusoro pemvura.
Kazhinji, ine fluffy uye inoratidzika kutaridzika, ndosaka ichizivikanwa kwazvo sechirimwa chemumvura, ichi chiri chikonzero chikuru nei ichiziviswa netsaona munzvimbo iri kure nenharaunda yaro kwayakabva.
Mashizha awo madiki muhukuru (anenge 1mm), iwo akareba, kana ovate, sessile (isina hunde kana petiole), akanyururwa zvakadzama neumwe neumwe, akabatanidzwa uye akamanikidzwa, izvo zvinovabvumira kufukidza zvizere zviyero, mukuwedzera, ine membranous uye inoshanduka-shanduka muganho. .
Saizvozvo, yavo sori yakabatana mukati mezvivakwa zvinozivikanwa se sporocarps, iyo zvakare yakavharwa nemashizha. Aya masisitimu, mune avo echirume akasiyana, anoonekwa nekuita idenderedzwa muchimiro, sessile, yakasarudzika uye isina zviyero kana bvudzi.
Saizvozvo, microspores vane idenderedzwa chimiro y vanokura mumapoka. Kune chikamu chayo uye musiyano wayo wechikadzi, ivo vanowanzo kuve pyriform, havana vhudzi kana zviyero, vane pendi yakapetwa, vane megaspore inomiririra kuve ine tuberculated yakawanda uye ine zvivakwa zvepamusoro zvinotendera kuti ifambe.
Ivo vane iyo kugona kusimukira mumvura ine pH inofungidzirwa ye5-7, uye zvakare yakapfava kana yepakati yakaoma mvura, ine tembiricha iri pakati pe10-28 ° C. Zvakakodzera kutaura kuti maAzolla filiculoides ane girini yakajeka uye pfumbu kana ari madiki, nepo pavanosvika pakukora vanochinja kuita pinki kana kutsvuka uye kusviba. Chii chimwe, ine yakareba yakareba uye midzi yakasimba nekukura mukati memamiriro ayo epakutanga.
Vagari vemuti uyu vane kugona kubvisa simbi dziripo mu mvura, mukati mayo mune semuenzaniso: mhangura, lead, chromium, nickel uye / kana zinc. Mushure meizvi, zvirimwa zvinokohwewa, kuomeswa uye kurapwa semarara akasimba, saka zvinobva zvanyatso goneka zvichienzaniswa nemarara emvura.
Iyo inofadza zvikuru kurima
Mupunga unowanzo kurimwa padunhu rakazara nemvura, saka munyika dzakasiyana siyana dzeAsia, zvakajairika kudyara chirimwa ichi mukati meminda yakatsaurirwa kurimwa kwemupunga kwemwedzi mishoma isati yadyara mupunga pachawo.
Izvi zvinodaro nekuti Azolla filiculoides inovhara zvachose mvura, ichidzivirira kukura kwemasora, uye kana mafern akangofa, vanopa nitrogen kuivhu reminda yekurima.
Nenzira iyi zvinokwanisika kudzivirira kushandiswa kwefetireza mafekitori, iyo mukuwedzera kune inodhura, inowanzo shatisa emvura semugumisiro weakawandisa nitrogen inoyerera ichibva pasi.
Chekupedzisira, zvinofanirwawo kutaurwa kuti iyi fern iri kuita dambudziko, nekuti iri kukanganisa, kunyangwe ivo vatove kutora matanho pamusoro penyaya iyi.
