Parasitic mbewu dodder: miyeso ulamuliro

Dodder - parasitic chomera mwina bwino kwa munthu aliyense; lianovidnym kukhala udzu oopsa, entwine zomera mbewu, izo sapereka yotsirizira kukhala bwinobwino, woyamwa zakudya pamodzi ndi umoyo wawo.

Kufotokozera dodder

A mbadwa ya Africa ndi otentha America, parasitic chomera dodder ali ponseponse ake dziko lonse lapansi; mosavuta kusinthasintha kwa zinthu zatsopano okha ndi zomera latsopano, chifundo pa iwo tiziromboti.

Yodziwika ndi chonde mkulu ndi mkulu viability, dodder zabwino ndi tolstostebelchatoy mawonekedwe, ndi amapezeka achilengedwe a mitundu zoposa 100.

Ambiri pulogalamu yaumbanda imatengedwa parasitic chomera dodder kumunda, clover, anakweranso, fulakesi. Mosatsata masamba ndi mizu, ali osiyana thupi mtundu (chikasu kuti utoto). Amagetsi kumulowetsa tiziromboti ndi mphamvu za mbewu makamu, amene amamangiriridwa mwa suckers pachiyambi (haustoria). Mapangidwe suckers awa, amene kudutsa kwambiri mu minofu chomera, ndipo mawere mwa izo zakudya amapezeka mu malo kukhudzana ndi "wovulalayo lotsatira". The Mmera wonse, umene wakhala akapolo a dodder, wofooka, kukula anachedwa ndi chitukuko chifukwa kutopa zakudya udzu.

Dodder kuvulaza mbewu

Dodder kukwawira amapezeka mofulumira udzu chimakwirira zosiyanasiyana lonse mbewu, kuchititsa kuchepa khalidwe la kupanga yozizira hardiness kuwonongeka ndipo ngakhale imfa ya mbewu m'tsogolo.

Dodder si capricious kusankha "tsogolo la wovulalayo" ndi moyo limodzi ndi m'munda ndi masamba mbewu iliyonse; Ine sindikufuna obwerera ku udzu izi ngakhale maluwa. Beveled pa udzu udzu, anakhudzidwa dodder, zoipa youma, sizitha thanzi, kungachititse matenda nyama zina - imfa yake.

Patapita parasitic chomera dodder prisosetsya mbewu yabwino, linaphwanya ubwenzi wake ndi nthaka, ndi namsongole kwathunthu anapereka chifukwa osankhidwa awo chinthu chachilengedwe. Mmodzi mwa kufuna kwa udzu angathe kupanga chotupa m'mimba mwake wa 6 sq. meters. Vegetative thupi dodder ali mkulu wakewe umafuna, walola nyenyeswa za zomera chiyani zokha kwa nthawi yaitali. Cuscuta makamaka akufotokozera m'mbali cham'mwamba ndi pakati pa zomera, enveloping iwo filiform, nthambi, wotumbululuka zimayambira chikasu.

Mapulaniwo dodder yokutidwa ndi chiwerengero chachikulu cha maluwa ang'onoang'ono pamodzi ndi ozungulira, kukwera kapena inflorescence klubochkovidnye. zipatso ndi kapisozi ndi mbewu 2 kapena 4. Yotsirizira kukhala mofanana kwa mbewu za zomera za mbewu, nthawi zambiri amakhala kuonedwa ngati amenewa. Mu mbewu makamaka dodder ngati mbewu clover, koma pa anayendera pafupi iwo akhoza kuwasiyanitsa. Masking mbewu dodder ndi mbewu ya zomera wobzalidwa chifukwa cha anatengera parasitic, amene complicates ntchito njira ochiritsira a kulekanitsa mbewu Chrixitu. Mbewu dodder, yodziwika ndi pamwamba mauna, ufa maginito wothira ndi wosiyana mbewu za zomera nalo electromagnets. yosalala pamwamba a ufa si anachedwa.

Kufalitsa dodder

Kufalitsa mbewu dodder zambiri amapezeka ndi mbewu bwino ankachitira. Ndipo zamoyo zina zake ndi nyama, mphepo makina, madzi; ngati ng'ombe kudyetsedwa zakhudzana zomera dodder, yotsirizira imagwera pa munda ndi manyowa a nyama. Komanso dodder akhoza kufalitsa ndi chidebe kapena zinthu kubzala. Gwero la matenda zingapangitse namsongole ndi zomera zakutchire ndi kachilombo deta tiziromboti. Dodder mbewu kumera kumachitika masiku 5-15 pambuyo kufesa, ndi nthawi yoyamba pali ndalama za magulu awo. Ngati dodder si kukumana yoyenera "breadwinner", iye amafa.

Tayani udzu ndi zovuta, chifukwa ntchito mankhwala sayambitsa ake pafupifupi vuto lililonse. Kuwononga udzu zimenezi zimatheka ndi mbewu yokha. Kugwiritsa zodzitetezera Cholinga chake kuteteza zikamera pa malo monga njiru tiziromboti achilengedwe.

Yofesa mbewu yoyenera kuti apange ufulu wa mbewu dodder ndi malo oyera. M'pofunika mbewu monga anayesedwa kudziwa mlingo wawo wa chiyero, kufufuza phytopathological ndi miyeso kwaokha. Pakuti kufesa zomera ayenera kusankha malo oyera. Mu madera a yothiriridwa ulimi kumera wa mbewu udzu yotithandiza zotenga kasupe ndi autumn kuthirira. Pamene Dodder mu udzu osatha, otsiriza isanayambe maluwa ndi seeding dodder ayenera kutchetcha. Makamaka polimbana yake ndikutchetcha munda dodder, 95% ya zimayambira zomwe zili umakhala pafupi nyemba zanu, amene amalola otsika odulidwa mosavuta kuwachotsa m'munda pamodzi ndi udzu. Kugwiritsa kwambiri kukumba dothi pa 25-30 cm.

Nkofunika kuteteza maonekedwe a m'dera namsongole oopsa, lomwe ndi parasitic chomera dodder. Ndipo menyanani nawo pogwiritsa ntchito njira zodzitetezera njira adzakhala chabe.
