Zowongolera kukula kwa zomera ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo, omwe amapangidwa mwaluso kapena kuchotsedwa ku tizirombo tating'onoting'ono ndipo amakhala ndi ntchito yofanana kapena yofananira ndi mahomoni amtundu wa zomera.Amayang'anira kukula kwa zomera pogwiritsa ntchito mankhwala ndipo amakhudza kukula ndi kukula kwa mbewu.Ndi chimodzi mwazotukuka zazikulu mu sayansi yamakono ya zomera ndi sayansi yaulimi, ndipo chakhala chizindikiro chofunika kwambiri cha chitukuko cha sayansi yaulimi ndi zamakono.Kumera kwa mbewu, mizu, kukula, maluwa, fruiting, senescence, kukhetsa, dormancy ndi zochitika zina zokhudzana ndi thupi, zochitika zonse zamoyo za zomera sizingasiyanitsidwe ndi kutenga nawo mbali.
Mahomoni asanu akuluakulu amtundu wa zomera: gibberellins, auxins, cytokinins, abscisic acid, ndi ethylene.M'zaka zaposachedwa, ma brassinolides adalembedwa ngati gulu lachisanu ndi chimodzi ndipo avomerezedwa ndi msika.
Zida khumi zapamwamba zopangira ndikugwiritsa ntchito:ethephon, gibberellik asidi, paclobutrazolchlorfenuron, thidiazuron, mepiperinium,mkuwa,chlorophyll, indole acetic acid, ndi flubenzamide.
M'zaka zaposachedwa, kampaniyo yakhala ikuyang'ana pa mitundu ya mankhwala osintha zomera: procyclonic acid calcium, furfuraminopurine, silicon Fenghuan, coronatine, S-inducing antibiotics, etc.
Zowongolera kukula kwa zomera zikuphatikizapo gibberellin, ethylene, cytokinin, abscisic acid ndi brassin, monga brassin, yomwe ndi mtundu watsopano wa zobiriwira komanso zachilengedwe zowonongeka kwa zomera, zomwe zingathe kulimbikitsa kukula kwa masamba, mavwende, zipatso ndi mbewu zina. mtundu wa mbewu, onjezerani zokolola, pangitsani mbewu kukhala zowala ndi masamba okhuthala.Nthawi yomweyo, imatha kusintha kukana chilala komanso kuzizira kwa mbewu, ndikuchepetsa zizindikiro za mbewu zomwe zikudwala matenda ndi tizirombo, kuwonongeka kwa mankhwala ophera tizilombo, kuwonongeka kwa feteleza ndi kuzizira kwachisanu.
The pawiri yokonza zomera kusinthidwa kukonzekera akukula mofulumira
Pakalipano, mtundu uwu wa pawiri uli ndi msika waukulu wogwiritsira ntchito, monga: gibberellic acid + brassin lactone, gibberellic acid + auxin + cytokinin, ethephon + brassin lactone ndi zina zokonzekera pawiri, Ubwino Wowonjezera wa olamulira kukula kwa zomera ndi zotsatira zosiyanasiyana.
Msika umakhazikika pang'onopang'ono, ndipo masika akubwera
Boma la State Administration of Market Supervision and Administration ndi National Standardization Administration lavomereza ndikutulutsa miyezo ingapo yamayiko yoteteza mbewu ndi zida zaulimi, pomwe kutulutsidwa kwa GB/T37500-2019 “Determination of Plant Growth Regulators in Fertilizer ndi High Performance. Liquid Chromatography” imalola kuyang'anira Mchitidwe wosaloledwa wowonjezera zowongolera zakukula kwa mbewu ku feteleza uli ndi chithandizo chaukadaulo.Malingana ndi "Pesticide Management Regulations", malinga ngati mankhwala ophera tizilombo awonjezeredwa ku feteleza, mankhwalawo ndi ophera tizilombo ndipo ayenera kulembedwa, kupangidwa, kugwiritsidwa ntchito, kugwiritsidwa ntchito ndi kuyang'aniridwa motsatira mankhwala ophera tizilombo.Ngati chiphaso cholembera mankhwala sichinapezeke, ndi mankhwala opangidwa osapeza chiphaso cholembera mankhwala molingana ndi malamulo, kapena mtundu wa chinthu chomwe chili mu mankhwalawo sichikugwirizana ndi zomwe zalembedwa palemba kapena buku la malangizo a mankhwalawo. , ndipo watsimikiza kukhala mankhwala abodza.Kuphatikizika kwa phytochemicals monga chinthu chobisika kumasinthika pang'onopang'ono, chifukwa mtengo wakusaloledwa ukukulirakulira.Pamsika, makampani ena ndi zinthu zomwe sizili zovomerezeka komanso zomwe sizigwira ntchito pang'onopang'ono zidzathetsedwa.Nyanja yabuluu iyi yobzala ndikusintha ikukopa anthu alimi amakono kuti afufuze, ndipo masika ake afikadi.
