Njira Yatsopano Yokulitsira Zokolola za Mitengo Yazipatso: Momwe Olamulira Kukula kwa Zomera Mwasayansi Amasinthira Kakulidwe Kakulidwe

Zowongolera zakukula kwa zomera ndi gulu la zinthu zopangidwa ndi mankhwala-zopangidwa mwachisawawa kapena zotengedwa mwachibadwa-zomwe zimatha kusintha kakulidwe ndi kakulidwe ka zomera. Njira yawo yayikulu yochitirapo kanthu imakhala kutsanzira kapena kusokoneza kaphatikizidwe kachidziwitso ka mahomoni amtundu wamkati (monga ma auxins, cytokinins, ndi gibberellins), potero amathandizira machitidwe amthupi monga kugawanika kwa ma cell, elongation, kusiyanitsa, ndi mapangidwe a ziwalo. Mu gawo laulimi, kugwiritsa ntchito zinthu izi kumapereka njira zasayansi zolimbikitsira zokolola, kukonza bwino, komanso kulimbikitsa kukana kupsinjika.


Tengani Brassinolide mwachitsanzo:ndi yogwira pophika zili 0,2%, izo zimagwira ntchito monga otsika kawopsedwe, kotheratu madzi sungunuka amino asidi zochokera foliar fetereza. Ikachepetsedwa ka 5,000 ndikupopera pamasamba amitengo yazipatso, imathandizira kwambiri kusamutsidwa kwa zinthu za photosynthetic kupita ku chipatso pomwe nthawi yomweyo imayang'anira kuchuluka kwa mahomoni okhazikika mumtengo, potero amachepetsa kugwa kwa maluwa ndi zipatso. Zoyeserera zoyeserera zikuwonetsa kuti pakatha kugwiritsa ntchito katatu motsatizana pamitengo yazipatso monga maapulo ndi malalanje, pafupifupi kulemera kwa chipatso kumawonjezeka ndi 15% -20%, ndipo chiŵerengero cha shuga ndi asidi chimawonjezeka. Kachitidwe kake kakuchitapo kanthu kumaphatikizapo kuyambitsa mapuloteni olandirira pa nembanemba ya cell kuti mbewuyo ikhale ndi michere yambiri, pomwe imapangitsa kuti ma jini okhudzana ndi kupsinjika azitha kupirira zinthu zoyipa monga chilala komanso kutentha pang'ono.

Kuchokera pachitetezo, chiwopsezo chapakamwa cha Brassinolide chimangokhala 0.0000000004, ndipo chiwopsezo chake chachikulu cha dermal ndi 0.000000067 - ziwerengero zomwe zili pansi pa chitetezo chokhazikitsidwa ndi mankhwala opha tizilombo. Kusungunuka kwake kwathunthu m'madzi kumatsimikizira kufalikira kofanana kwa njira yopopera pamasamba, potero kuchepetsa chiwopsezo cha phytotoxicity chifukwa cha kuchuluka kwambiri komwe kumachitika. Pankhani ya kuwongolera kwa mlingo, chiŵerengero cha dilution cha 0.2% -0.5% ndichokwanira kukwaniritsa zofunikira zoyendetsera kukula ndikupewa zinthu monga kumera msanga kwa zomera kapena kuwonongeka kwa zipatso zomwe zingabwere chifukwa chogwiritsa ntchito mopitirira muyeso. Ndikoyenera kudziwa kuti mphamvu za olamulirawa zimakhudzidwa kwambiri ndi nthawi yogwiritsira ntchito; Choncho, tikulimbikitsidwa kuti tiziwagwiritsa ntchito panthawi yovuta kwambiri ya chitukuko-monga gawo la kusiyanitsa kwa maluwa ndi gawo la kukula kwa zipatso zachinyamata-kuti akwaniritse zotsatira zabwino kwambiri.


Pazaulimi wamakono, kugwiritsa ntchito zowongolera kukula kwa zomera zasintha kuchoka ku ntchito imodzi kupita ku njira zambiri zogwirira ntchito, zophatikizika. Kupyolera mu mgwirizano wamagulu osiyanasiyana, zolinga zambiri-monga kulimbikitsa kukula, kulimbikitsa kukana kupsinjika maganizo, ndi kuwongolera khalidwe-zingathe kukwaniritsidwa nthawi imodzi. Kusinthika kwaukadaulo uku kukuwonetsa kufunikira kwaulimi wamakono kuti pakhale malamulo olondola komanso kumapereka malingaliro atsopano othana ndi zovuta za ulimi wokhazikika pakati pazovuta.
