Feem ntau, yuav cov noob rau cog, ntawm lub hnab koj tuaj yeem nrhiav lub npe "parthenocarpic ntau yam". Tib lub sij hawm, nws ua tsis meej rau ntau tus neeg yuav khoom dab tsi lub sij hawm "parthenocarpic" txhais tau tias.
"Parthenocarpic" txhais li cas?
Qee cov producers sim ntxias cov ntawv sau no thiab qhia hauv cov khoom siv "tus kheej-pollinated" los yog "tsis tas yuav ua kom tus kabmob". Txawm li cas los xij, cov ntawv sau no muaj ntau lub ntsiab lus.
Muaj ntau yam los yog kab ntawm cov nroj tsuag uas yog self-pollinated muaj ob lub pestle thiab stamens. Lawv ua rau pollinate lawv tus kheej, thiab dais txiv hmab txiv ntoo nrog noob.
Parthenocarpic txiv hmab txiv ntoo yog cov nroj tsuag ntau yam uas rau cov txiv hmab txiv ntoo uas tsis muaj pollination. Nyob rau hauv rooj plaub no, lub txiv hmab txiv ntoo yog tau yam uas tsis muaj noob.
Kev pom zoo rau kev siv ntawm parthenocarpic ntau yam los yog hybrids
Xws li ntau yam tsim nyog rau kev loj hlob cov qoob loo nyob rau hauv tsev xog paj tej yam uas tsis muaj muv los yog lwm yam kab uas yuav ua rau pollination. Nyob rau hauv greenhouses thiab greenhouses nyob rau hauv no txoj kev cultivate zoo cov qoob loo. Nyob rau hauv rooj plaub no, nws yog ib qhov tsis yooj yim sua kom tau cov noob.
Nws yuav tsum tau muab rau hauv tus account tias yog pollination ntawm parthenocarpic ntau yam los ntawm bees tau tshwm sim, qhov no ua rau tsim ntawm txiv hmab txiv ntoo curves (piv txwv li, cucumbers). Yog li ntawd, cultivation ntawm xws ntau yam rau qhib txaj yuav tsum tau txiav txim tawm. Tsis tas li ntawd, parthenocarpic hybrids yog ob los yog peb zaug ntau kim nyob rau hauv tus nqi. Siv lawv rau kev noj nyob sab nraud yog irrational.
Yog li, yog tias koj xav tau yuav cov noob cog rau hauv greenhouses, koj yuav tsum them nyiaj rau cov hnab ntawv nrog cov ntawv sau "parthenocarpic".
