Oyang'anira kukula kwa zomera ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo, omwe amapangidwa mwaluso kapena kuchotsedwa ku tizilombo toyambitsa matenda ndipo amagwira ntchito zofanana kapena zofanana ndi mahomoni ochokera ku zomera. Amalamulira kukula kwa zomera pogwiritsa ntchito mankhwala ndipo amakhudza kukula ndi chitukuko cha mbewu. Ndi chimodzi mwa zinthu zazikulu zomwe zapita patsogolo pa sayansi ya zomera zamakono komanso sayansi ya ulimi, ndipo chakhala chizindikiro chofunikira cha kukula kwa sayansi ya zaulimi ndi ukadaulo. Kumera kwa mbewu, mizu, kukula, maluwa, zipatso, ukalamba, kukhetsa, kugona ndi zochitika zina za thupi, zochitika zonse za moyo wa zomera sizingasiyanitsidwe ndi kutenga nawo mbali kwawo.
Mahomoni asanu akuluakulu ochokera ku zomera: gibberellins, auxins, cytokinins, abscisic acids, ndi ethylene. M'zaka zaposachedwa, ma brassinolides alembedwa ngati gulu lachisanu ndi chimodzi ndipo avomerezedwa ndi msika.
Zomera khumi zapamwamba zopangira ndi kugwiritsa ntchito:ethephon, asidi wa gibberellic, paclobutrazol, chlorfenuron, thidiazuron, mepipenium,brassin,chlorophyll, indole acetic acid, ndi flubenzamide.
M'zaka zaposachedwa, kampaniyo yakhala ikuyang'ana kwambiri mitundu ya zinthu zosinthira zomera: procyclonic acid calcium, furfuraminopurine, silicon Fenghuan, coronatine, maantibayotiki oyambitsa matenda a S, ndi zina zotero.
Oyang'anira kukula kwa zomera ndi monga gibberellin, ethylene, cytokinin, abscisic acid ndi brassin, monga brassin, yomwe ndi mtundu watsopano wa olamulira kukula kwa zomera wobiriwira komanso wosamalira chilengedwe, womwe ungalimbikitse kukula kwa ndiwo zamasamba, mavwende, zipatso ndi mbewu zina, ukhoza kukweza ubwino wa mbewu, kuwonjezera zokolola, kupangitsa mbewu kukhala zowala komanso masamba okhuthala. Nthawi yomweyo, ukhoza kupititsa patsogolo kukana chilala komanso kukana kuzizira kwa mbewu, ndikuchepetsa zizindikiro za mbewu zomwe zikudwala matenda ndi tizilombo toononga, kuwonongeka kwa mankhwala ophera tizilombo, kuwonongeka kwa feteleza ndi kuwonongeka kwa kuzizira.
Kukonzekera kwa mankhwala opangidwa ndi zomera kukukula mofulumira
Pakadali pano, mtundu uwu wa mankhwala uli ndi msika waukulu wogwiritsidwa ntchito, monga: gibberellic acid + brassin lactone, gibberellic acid + auxin + cytokinin, ethephon + brassin lactone ndi zina zopangira mankhwala, Ubwino wowonjezera wa owongolera kukula kwa zomera ndi zotsatira zosiyanasiyana.
Msika umakhala wokhazikika pang'onopang'ono, ndipo masika akubwera
Boma la Unduna wa Zamalonda ndi Unduna wa Zamalonda ndi Unduna wa Zamalonda avomereza ndi kutulutsa miyezo ingapo yadziko lonse yotetezera zomera ndi zipangizo zaulimi, kuphatikizapo kutulutsidwa kwa GB/T37500-2019 “Kutsimikiza kwa Olamulira Kukula kwa Zomera mu Feteleza ndi High Performance Liquid Chromatography” kumalola kuwunika. Mchitidwe wosaloledwa wowonjezera owongolera kukula kwa zomera ku feteleza uli ndi chithandizo chaukadaulo. Malinga ndi “Pesticide Management Regulations”, bola ngati mankhwala ophera tizilombo awonjezedwa ku feteleza, zinthuzo ndi mankhwala ophera tizilombo ndipo ziyenera kulembetsedwa, kupangidwa, kugwiritsidwa ntchito, kugwiritsidwa ntchito ndi kuyang'aniridwa motsatira mankhwala ophera tizilombo. Ngati satifiketi yolembetsera mankhwala ophera tizilombo siipezeka, ndi mankhwala ophera tizilombo opangidwa popanda kupeza satifiketi yolembetsera mankhwala ophera tizilombo malinga ndi lamulo, kapena mtundu wa mankhwala ophera tizilombo omwe ali mu mankhwala ophera tizilombo sugwirizana ndi mankhwala ophera tizilombo omwe ali pa chizindikiro kapena buku la malangizo a mankhwala ophera tizilombo, ndipo apezeka kuti ndi mankhwala ophera tizilombo abodza. Kuwonjezera kwa mankhwala a phytochemicals ngati chosakaniza chobisika kumasinthasintha pang'onopang'ono, chifukwa mtengo wa kusaloledwa ukukwera kwambiri. Msika, makampani ena ndi zinthu zomwe si zovomerezeka komanso zomwe zimagwira ntchito yochepa pamapeto pake zidzachotsedwa. Nyanja yabuluu iyi yobzala ndi kusintha zinthu ikukopa alimi amakono kuti akafufuze, ndipo masika ake afikadi.
