La setmana passada els alumnes d’Aula Oberta van comen\u00e7ar a condicionar l’espai del futur pati amb hort. Hem tret algunes herbes, sobretot les m\u00e9s altes, i hem netejat les jardineres. Tamb\u00e9 hem recollit les escombraries que part de l’alumnat llen\u00e7a a l’espai de l’hort, per tant, fem una crida a utilitzar les papereres.<\/p>\n

Per\u00f2 no hem tret totes les plantes! N’hem deixat algunes que ens estan ajudant a cuidar el s\u00f2l amb la seva feina. Tothom t\u00e9 clar que les plantes son \u00e9ssers vius, per\u00f2 el s\u00f2l, aparentment inert, \u00e9s un complex ecosistema ple de vida microsc\u00f2pica i no tant microsc\u00f2pica, on hi circulen nutrients, aigua… i on hi tenen lloc importants cicles naturals, com el del carboni o el nitrogen.<\/p>\n

Aquestes plantes espont\u00e0nies que surten sense l’ajuda de ning\u00fa col\u00b7laboren per a que el s\u00f2l trobi el seu equilibri, despr\u00e9s d’haver patit alguna pertorbaci\u00f3 ambiental. Tots els s\u00f2ls, per molt degradats que estiguin, aspiren a omplir-se de vida i aquestes plantes espont\u00e0nies son les pioneres que comencen a obrir cam\u00ed a la biodiversitat, i que mantenen el s\u00f2l viu. No heu vist mai un llets\u00f3 obrint-se pas incl\u00fas entre l’asfalt? Doncs aquesta for\u00e7a tenen aquestes petites plantes espont\u00e0nies, sovint considerades males herbes, invisibles, per\u00f2 molt poderoses i resilients, perqu\u00e8 creixen en espais dif\u00edcils, i a m\u00e9s, ens donen molta informaci\u00f3.<\/p>\n

Si deix\u00e9ssim el s\u00f2l nuu (sense plantes cobertores), aquest faria una crosta cada cop m\u00e9s dura per protegir la humitat de les capes internes del s\u00f2l, i aix\u00f2 al seu torn, dificultaria la infiltraci\u00f3 de l’aigua de pluja, fent que el s\u00f2l estigu\u00e9s m\u00e9s deshidratat i per tant, amb m\u00e9s dificultat per albergar vida. Ho heu sentit all\u00f2 de “l’aigua \u00e9s vida?” Doncs aix\u00f2 mateix \ud83d\ude42 Per tant, deixar aquestes plantes ens ajuda en una multiplicitat de funcions: mantenir la humitat del s\u00f2l, que no perdi la seva estructura, mantenir-lo airejat amb el pas de les arrels, protegir la feina dels petits organismes que habiten les capes subterr\u00e0nies, controlar les emissions de carboni a l’atmosfera (com m\u00e9s calenta est\u00e0 la terra, m\u00e9s di\u00f2xid de carboni allibera, per tant, deixar aquestes plantes evita que augmenti la temperatura, i que s’alliberin emissions de carboni a l’atmosfera). A m\u00e9s a m\u00e9s, algunes d’aquestes plantes ens ajuden a fixar nutrients, especialment les de la fam\u00edlia de les lleguminoses (com el tr\u00e8vol vermell, el lotus…) que capturen nitrogen atmosf\u00e8ric amb l’ajuda de les bacteries rhizobium i el fixen al s\u00f2l, aportant fertilitat comunit\u00e0ria. O la pastanaga silvestre, que amb les seves arrels aireja i descompacta, i tamb\u00e9 atrau fauna ben\u00e8fica.<\/p>\n

A les fotografies, us en presentem algunes, per ordre d’aparici\u00f3: 1. Tr\u00e8vol vermell o fenc bord (Trifolium pratense); 2. lotus banyut (Lotus corniculatum); 3. verbascum; 4. pastanaga silvestre o borda (Daucus carota L. subsp. Carota); 5. plantatge de fulla estreta o de cinc nervis (Plantago lanceolata); 6. plantatge de fulla ampla (Plantago major); 7. colitxos, conillets o alf\u00e0brega de ca (Silene latifolia) .<\/p>\n\n\n\n

Un altre dia us explicarem la difer\u00e8ncia entre esp\u00e8cie, g\u00e8nere i fam\u00edlia, i tamb\u00e9 perqu\u00e8 necessitem el nom cient\u00edfic per no confondre’ns de planta, ja que en la majoria de casos us hem donat el nom de les esp\u00e8cies (nom popular i nom cient\u00edfic) per\u00f2 en un \u00fanic cas, nom\u00e9s el g\u00e8nere, doncs no podem saber l’esp\u00e8cie sense veure la flor (i ja ha desaparegut) . Sabeu de quina planta nom\u00e9s us hem donat el g\u00e8nere?<\/p>\n
