Sei mashizha kutendeukira tsvuku zvirimwa. Sei kutendeuka yeyero uye kuwa mashizha

It yagara vakaratidza kuti miti - vari venyama mupenyu. Ivo, pamwe chete mhuka zvokudya, kufema, bereka. Zvaitika zviuru nokukanganisika siyana anobudiswa zvinokurisa zvinobatsira, kusanganisira kudzikisirana zvigadzirwa rakabva muviri. Ndiko, zvose kwemasayendisiti kuti unhu kuratidzwa upenyu, aripo zvirimwa kuti pasi redu kusimba yakanaka, zvakachena uye zvakasiyana-siyana.

zvoutachiona mutinhimira

Sei zvirimwa fema? Nei mashizha kutendeuka yero mavari? Chii chavanoita kudya? How zvikure? mibvunzo yakawanda inomuka nevaya vanoona zvisikwa izvi zvinoshamisa sezvo siyana, akanaka, inopenya uye mavara.

Zvinomera zvose vanoonekwa ne imwe mutinhimira zvipenyu, uyewo nezvimwe zvinhu zvipenyu. Idzi dzinosanganisira:

• dehiscence Mafundo uye kuvhara dzavo pasi pokudzora kureba kwakaita chemasikati uye makemikari anoumba kwezvakatipoteredza;
• ndichibvunza kuwedzera uremu vanopukunyuka;
• compression uye Panovhurwa stomata pamusoro mashizha;
• kuwedzera kana kutapudza kufema, photosynthesis;
• defoliation uye nevamwe.

Saka, mhinduro yomubvunzo wokuti nei mashizha kutendeuka tsvuku zvirimwa, riri zvigadziriswe pakati chaivo mutinhimira. azvaiitwa kuvabvumira kuti ajairane zvakatipoteredza ezvinhu kurarama madziri, kuti tiite mabasa anokosha sezvo zvakanyanya sezvinobvira, kuti akure kupindura makemikari mumuviri migumisiro kubva hunhu wemunhu, mhuka uye zvichingodaro.

Nei mashizha kutsauka yero mumiti, somuenzaniso? Uyewo mumwe kuratidzwa zvipenyu mutinhimira, zvainanga kuchengetedza chinhanho kubva specimens yakaderera tembiricha kuderedza uwandu chezuva uye unyoro. Ruvara lamina akatsunga chaiwo zvinhu zvayo sezvamunoita.

Dyarai pigments ari mashizha

Sei kutendeuka yeyero idonhe mashizha? Hongu, nokuti pane nokubatanidzwazve nemakemikari mukati chirimwa muviri. Mumwe mumiririri Flora rine wayo maumbirwo dzinoverengeka pigments - zvinhu kuti kuona ruvara nhengo (mashizha, nekorona maruva, madzinde, uye zvichingodaro). Kune mapoka makuru mana yeimwe izvi vangazivikanwa:

1. Chlorophyll. Ruvara rine ayo maumbirwo imwe magnesium nokuo- nga uye wandei porphyrin zvindori. Anopa miriwo uye zvikamu mupfumi zvakasvibirira ruvara, ari kuitika mune chirongwa photosynthesis. Zviri rawo miti exchange rezuva chiedza simba kupinda nemakemikari simba. Saka kuumbwa kupembedza inotonhorera - starch. Under akanaka ezvinhu makwenzi chlorophyll ari voruzhinji, zvisinei mamwe pigments vasiri richiratidzwa.
2. Xanthophylls. remubatanidzwa izvi zviri chikamu zvose vanhu, asi kwete kuratidzwa, pasi wakakodzera ezvinhu, nokuti chlorophyll iri woutsinye. algae Vazhinji Corolla ruvara ruvara ari dzakanzi ino inoratidza pacharo, pova yeyero ruvara.
3. Carotenoid. The orenji Ruvara mashizha, davi zvikamu Corolla richinzi chaiyo nokuda akakura ichi. Kazhinji woutsinye chlorophyll hworatidza pacharo chete pamusoro panowanikwa yakaderera tembiricha kwakaomarara dzezvakatipoteredza ezvinhu.
4. Anthocyanins - pigments kuti kuti paumbwe akanaka tsvuku hues mune miti mumativi. Sezvakangoita rapfuura maviri, riri kuratidzwa kwayo dzinongoitika muchimiro chete maruva Corolla kana matope (dzvuku algae). Kuchinja zvinhu uye kuparadzwa porphyrin chindori chlorophyll ari hwakasimba mugumisiro anthocyanins.

Vose pigments izvi pakutanga vakapiwa kwokunze pavakanzwa nokuchinja mamiriro vanhu. Nei mashizha kutsauka tsvuku zvinomera, zvichiita zviratidzo zvakadai, kunyatsotarisisa.

VaBennett shizha kuwa miti

Chiitiko mashizha kuwa - mumwe yakaisvonaka zvakasikwa. Ndokusaka matsutso - a kufarira nguva gore vadetembi zhinji. Pashure pezvose, yakapoteredza runako havangagoni kuva bhuku rakafuridzirwa vanhu okusika. Multicolored denderedzwa, yellow, mutema, tsvuku, orenji kana kunyange brownish-dzepepuru hues nyore anopenyerwa, uye munhuwi mashizha akawa munhuwi mate kufadzwa.

Chii chakaita kuchinja kwakadaro uye kana nguva dzose zvakarurama? Funga zvikonzero shizha akawapo miti. Vanogona kuva mapoka mapoka maviri: dzinongoitika uye vanomanikidzwa. Mumwe zvinosanganisira dzinoverengeka zvinhu, uye tsanangudzo kwavari.

dzinongoitika

Nokuti avo zvikonzero zvinosanganisira pamwaka kuchinja mamiriro okunze, uyewo shanduko pakureba masikati. All zhizha mitema hofori vari kugadzirira mutinhimira kuchinja ichi. Wanda uye chitoro zvinovaka muviri ari madzinde dzavo hunde, rinoitwa achishingaira dzinotsanagura photosynthesis uye afemeruke unopisa kufadza zvinoita huwandu unyoro.

Pakatanga chando, chiedza pfupi mazuva kutendeuka kutanga mukati papepa kwamahwendefa.

1. The ruvara chlorophyll anotanga ishande maduku, ruvara rwunopera. Izvi zvinopa mukana wokuratidza vamwe pigments. Somugumisiro, mashizha kutendeukira yero, tsvuku uye zvichingodaro. Chii chichava noruvara wawira anosiya napo majini unhu muti marudzi. Uye zvinofadza chokwadi chiri chaipenya kupfuura zuva mumatsutso, chlorophyll anotanga nokukurumidza, uye mashizha kutendeukira tsvuku. Panguva madzvotsvotsvo miti yakareba zvinofadza greenery.
2. Munguva yezhizha ari muzvizhinji kuti ndiro machira vaunganidza metabolic zvigadzirwa, munyu, chicherwa zvinhu. Izvi zvinoita kuti jira rakaoma, uye zvishoma nezvishoma anotanga flake kure munzvimbo iri petiole kubva kwedzinde.
3. At mujinga hunde, pakati pavo uye hunde, kutanga pezvakaitwa chaiwo jira rukoko zvishoma nezvishoma anoramba papepa.
4. Nokupesvedzera zvemaziso zvinhu (mvura, mhepo, dutu, etc.), yayo giravhiti ose mashizha kutanga kuwira mumwe nomumwe.

kumanikidzwa

On mubvunzo wokuti nei mashizha kutendeuka tsvuku, pane imwe mhinduro. Izvi zvinoitika nokuti chibharo zvikonzero, yakadai se:

• kungoerekana tembiricha nokufamba;
• nokushaiwa chicherwa kudya;
• kushaya munhu zvakakwana yakawanda unyoro kana yemuraudzo;
• utsinye zvakananga chiedza chezuva;
• chisvetasimba chinhanho.

Zvinhu izvi kutungamirira vasanyanye chinhanho miti. Ndicho chikonzero mashizha kutendeukira yeyero kwavari.

kuchengeta maruva anosimwa mumba

Chikwata vakawanda kunomutsa mubvunzo: "Nei mashizha vatendeukire maruva tsvuku" Kazhinji uchaona vachirembedza zvikamu zvinomera, avo hakuvaki, pakuonekwa rakachenuruka, uye ichi rinoshanda kwete chete maruva marudzi, asi uyewo ferns, redkotsvetuschih zvinomera uye Succulents. Ndechipi chikonzero, edza kunzwisisa.

zvinokonzera yellowing

Nei mashizha kutsauka yero ruva?

1. Kunwisa kana kukwana achidiridzira.
2. Too inopenya zuva kana kuishaya.
3. Kushaikwa potassium, magnesium nezvimwe zvicherwa.
4. The kukundwa chikamu nhungirwa kana mudzi zvipukanana.
5. Zvakawandisa guruva, notumwe uye utachiona.

Ava ndivo vakawanda zvinokonzera yellowing nemashizha zvinomera.

Nzira Achabvisa chinonakidza

Usati chiito, unofanira kuona zvariri kukonzera sei mashizha kutendeukira tsvuku ruva. Kuti aite izvi, ongorora kutarisira zvinhu mumwe nomumwe chirimwa, chaizvoizvo chimwe chazvo kunoda munhu kusvika.

Next, unofanira kutirambidza vakaomerwa chinhu okukura: kana zviri kukwana kudiridza - kuwedzera kana zvakawandisa - kuderedza, kudzivirira kubva kuzuva, kana kuti kuwedzera izvozvo, isa fotereza pamwe makemikari fetiraiza, asi kwete overdo nayo. Chinhu chikuru - yeuka kuti maruva vanoda utsanana. Naizvozvo, vanofanira kuchengetedzwa kubva muguruva, marara uye utachiona.
