Chii duku ruva munyika?

Chirimwa nyika iri huru uye kusimba siyana. Pakutanga 2010, botanists ndakadzidza uye vakarondedzera zvuru 320 zvinomera, kusanganisira anopfuura 280,000 - maruva. Maererano rokutanga Kutara masayendisiti, nyika inokura hapana asingasviki zviuru 500 siyana kwemarudzi zvinomera! Nyaya rinotaura pamusoro duku ruva kwenyika. Below uchawana rondedzero yakatodzama zvainyanya.

tsananguro

Chii iduku ruva munyika? Zita chishamiso ichi - Wolff. Izvi chirimwa hwemvura rwevharanda yepamusorosoro maruva monocot, ndowenyika mhuri Araceae, subfamily - Lemnaceae ane 11 marudzi.

duku ruva nyika ino ane bhora chimiro, zvishoma flattened laterally, inopenya zvakasvibirira kana yellowish. Kureba hazvirevi kupfuudza 1-1.4 neMM, upamhi - 0.5-1 neMM, ari "rinorema" bhora vakawanda anoyera hapana anopfuura 200 micrograms. Enzanisa: kudivi rimwe machisa musoro kunogona kukodzera maruva aya anenge 30!

Wolffia - rootless chirimwa, muviri wayo ane akaderedza dhiramu chomukati umo stomata vari nemhepo, kureba microns 12-14 chete. Uchibatsirwa wavo, gasi Exchange rinoitwa pakati Wolf uye zvakatipoteredza. On hunde dzacho panguva maruva, muna July uye August, pane kaduku ruva, mumwe chinyakare mu chimiro, asi achiri ane pistil uye Stamens nomudzimai. Funga izvozvo chete nemaikorosikopu, vasina ziso havagoni kuiona, saka iduku.

waridza

duku ruva munyika iri subtropical. Mhando dzose zvirimwa zvikure mumvura yakachena pamwe simba dzenzvimbo muna North uye West Africa, South uye Central America uyewo Asia. chete nomutsa Wolfia arrhiza inokura kumaodzanyemba latitudes yeRussian Federation.

The chirimwa anonzwa zvakanaka uye kushingaira Kunowedzera chete apo tembiricha mvura iri zvinobva + 23 ° C kusvika 29 ° C. At dzakakwirira prices wolffia arrhiza Dries. Saka unogona kukunda tembiricha donhwe kusvika 15 ° C.

kubereka

Wolffia inoparadzirwa ainyanya vegetatively. Muchiitiko chino, pane nzira mbiri:

• dzidzo ari amai muviri nemaziso otrostochka kuti Paaizosvika zvizere kukura, uye hakuna kutanga "mukuru" upenyu;
• mumwe weboka mubereki gunde kupinda akawanda zvikamu, kazhinji 2 kana 3.

Kana mamiriro okunze akanaka, zvino ruduku ruva wenyika Anowanza nokukurumidza. In dzinopisa, pose chero mira mvura dziva chinofukidza uswa makapeti zvinomera izvi.

Wolffia arrhiza ane yakafarikana kugovera nzvimbo. Izvi imhaka ayo mamiriro: pemvura balls zvishoma kunama, nokuda izvo vanogona nyore kubatanidzwa chero chinhu chiri mumvura apo chirimwa mupenyu. The balls saka "akatamira" kune imwe nzvimbo itsva.

Makemikari anoumba: kubatsirwa uye pokukuvadza nokuda Wolffia

duku ruva zvenyika nezvi- mavhitaminzi A, C, B, PP. Wolffia mapuroteni unotora mari yakafanana Sou, saka muti mudukuduku zvemo kushandisa zvokudya, sezvo ruva ichi nomoyo kudya hove akwariyamu.

Wolffia bioochistitelem Zvisinei, masayendisiti akawana kushandiswa maindasitiri sedimentation Matangi: mitema balls yakasvinwa mvura, achinatsa kubva munyu inorema simbi.

Zvisinei, kazhinji zvinoita zvinoparadza Paddy minda, saka ari kushingaira vachirwira mupunga kurimwa.

Zvino iwe kupindura zviri nyore mubvunzo chii iduku ruva munyika.
