Ndeapi mabasa ezvirimwa?

Zvese zvipenyu zvinovimba nezuva kuti zvivepo chaizvo. Isu tiri pane imwe nyika iri iyo chaiyo chinhambwe kubva kuna nyeredzi mambo, uko kwainogamuchira mwaranzi yezuva neyakafanira musimba, iyo inobvumidza avhareji tembiricha ye14 degrees Celsius: yakanaka kune hupenyu. Kubva kwatakatanga kusvika nhasi, zvinoita sekunge zvisikwa zvezvirimwa zvakasiyana zvakanyanya, asi chokwadi ndechekuti mutsetse unokamuranisa unoparadzanisa maumambo ese ari kuramba uchisviba.

Sei? Zvakanaka ichokwadi kuti havagone kutaura kana kufamba, asi kuti vararame vanofanirwa kuita akateedzana mashandiro emiti, izvo zvakakosha pakupona kwavo. Ngatione kuti ndeapi makuru.

Kufema

Kufanana nemhuka ipi neipi, zvirimwa zvinoda kufema, uye zvinozviita nenzira yakafanana kwatiri: kutora oxygen uye kudzinga kabhoni dhayokisaidhi nemvura muchimiro chemhute. Vanofemera kupi? Mune zvikamu zvitatu:

• Stomata kana pores: Dzinowanikwa munzvimbo dzadzo dzese dzakasvibira, dzakaita semashizha, masimbi asina kusimba, mabrakti egirini (akachinjika mashizha anodzivirira ruva).
• Lenticels: iwo madiki protrusions, denderedzwa kana akareba, anowanikwa pane huni madzinde. Ivo vanoonekwa kune vakashama ziso, sezvo vachigona kuyera kubva pa1 kusvika pa5cm.
• Estate: nebvudzi rakakura.

Mubvunzo waungave uchizvibvunza iwe ndewekuti, vanofema zuva rese here? Husiku chete? Zvakanaka mhinduro ndeye ...: vanofema maawa makumi maviri nemana. Uye ndezvekuti, dai zvainge zvisina kudaro, vaisakwanisa kuita photosynthesis.

Photosynthesis

Iri ndiro basa rinoitwa chete nemiti. Mhuka dzinogona kuvhima mhuka, kana kudya kumakwenzi uye / kana michero, asi chirimwa chirimwa, kubva panguva iyo mbeu inomera kusvikira yafa, gara wakanamatira panzvimbo imwechete. Kuti vakure uye vakure, ivo vanofanirwa kukwanisa photosynthesize; ndokuti, shandura simba rezuva riite chikafu.

Zvinoitirwa kupi? Pamashizha. Izvi, sezvatinoziva, zvakasvibirira, sezvo zvine chlorophyll. Nekutenda kwazviri, vanogona kutora mwenje wakaringana, uyo pamwe chete nekabhoni dhayokisaidhi, inotendeuka kubva kune mbishi yakasvibira (mvura nezvicherwa zvinonwiwa nemidzi uye zvinonangiswa kumashizha) kuita muto wakagadzirwa (chikafu chemuti, chinoumbwa neamino acids uye neshuga kunyanya).

Semhedzisiro, zvinomera zvinoburitsa oxygen mumhepo kuburikidza ne stomata. Asi chete panguva yemasikati, inova iyo iyo pavanoratidzwa kune chezuva.

Zvokudya

Zvirimwa, pasina chikafu, zvaisakwanisa kukura, asi pasina mvura havangatokwanise kumera. Pauriri kune huwandu hwezvikafu, kunyanya nitrogen, phosphorus uye potasium (kana NPK), izvo zvinongowanikwa chete kana zvanyungudutswa mumvura. Kana vachinge vangoita, iyo midzi inozogona kuvayamwa pasina dambudziko hombe.

Chii chinonzi NPK chinobatsira? Nezve zvinotevera:

• Nitrogen: zvakakosha kuti ivo vakure, vagadzire chlorophyll uye vaite photosynthesis.
• Phosphorus: inoshanda kuitira kuti vagone kukudziridza yavo midzi sisitimu uye nekukura kwemichero.
• Potasiamu: yakakosha kwazvo, nekuti inopindira mukufema kwemiti uye mukutakura kwechikafu.

Kana midzi yacho yangowana mvura uye zvicherwa zvacho zvanyungudika mariri kubva pasi, musanganiswa unonzi sora mbishi, inotenderera nenzira inokwira kuburikidza nemidziyo ine huni kusvika yasvika pamashizha. Iko, kuburikidza nefotosinthesisi, inoshandurwa kuita yakajeka SAP, inoitiswa zvakadzikira nemidziyo yeLiberia kunzvimbo dzese dzemuti iri. Izvo zvakasara zvinhu zvinochengetwa uye zvinogara sezvakachengetwa

Kukura munzira yezuva

Sezvataona, Zuva rakakosha kuzvirimwa. Ivo vanochida icho chaizvo pazvinhu zvese. Sezvo mbeu ichimera, zvavanoita zvinokura munzira yechiedza chayo. Asi vanozviita sei? Sezvinei, Ungaudza sei hunde kuti ikure kumusoro uye midzi pasi?

Iyi mhinduro kumagetsi ezuva anozivikanwa se phototropism. Akadaro kukurudzira inokonzeresa kuita kwehomoni mumuti, mhedzisiro yacho kukura kwekusiyana inokonzerwa neaxin. Inoita nenzira yakasarudzika: kana paine mhinduro isina kunaka yefototropic, ndiko kuti, kana ichinge yakura yakanangana neZuva, inoiswa mudunhu remuti wakatarisana nechiitiko chechiedza. Pane kupokana, kana iyo phototropic mhinduro iri yakanaka, auxins akaiswa mukati muhuwandu hukuru uye, nekudaro, maseru mumatunhu aya anokura zvakanyanya kupfuura mune ayo ari mashoma mashoma.

Nekudaro, iyo midzi ine yakashata phototropism, nepo madzinde aine yakanaka phototropism.

Wanga uchiziva here kuti chii chikuru mashandiro emiti?
