Umphumela wemilingo we-gibberellic acid: imfihlo yokuvuselela izitshalo

Eminyakeni yamuva nje, i-Regulator yokukhula kwesitshalo Gibberellic Acid (GA3) ihlehlise ukuguquguquka kwezinguquko emikhakheni yezolimo kanye ne-horticulture. Ukusuka elabhorethri kuya ensimini, lokhu "ukushintshwa kwempilo yezitshalo" kudicilela phansi ukuqonda kokutshala kwendabuko. Ngokusho kwesifundo esingu-2022 yisikhungo sesayensi yamaShayina, ukusetshenziswa kwesayensi kwe-Gibberellic Acid (GA3) kungakhulisa izivuno zezilimo ngo-15% -20%, futhi namazwe angama-37 emhlabeni jikelele awufake kukhathalogi esemthethweni yokuphromotha.

1. "I-Accelerator" yokukhula kwezitshalo: Ukuhlukana nemikhawulo yofuzo
I-Gibberellic Acid (GA3) ingathuthukisa kakhulu ukusebenza kahle kwe-synther ye-cell elongation ngokwenza iprotheni ye-gibberellic acid (GA3) ezitshalweni. Ukuhlolwa eShizuoka University eJapan kuqinisekisile ukuthi izinga lokuqothuka kwezithombo zezithombo zamatamatisi afafazwe nge-0.5ppm GA3 kwakuyizikhathi ezingama-2.3 ngokushesha kunalezo zeqembu lokulawula. Okuthusa okwethusayo ukuthi iqembu leChina Ezolimo Enyuvesi likhuphule ngempumelelo ukusebenza kahle kwe-Gibberellic Acid (GA3) Synthesis Meat nge-40 ngobuchwepheshe bokuhlela iGene, okwenza isivuno sesitshalo esisodwa sommbila sidlula umaki we-1,200 kg wedlula i-1,200 kg umaki.

2. "Ukhiye weGolide" ukwephula i-dormancy: ukuvusa ubungqabavu obushisayo
I-Gibberellic Acid (GA3) ikhombise amakhono okulawulwa okuqondile kwezilimo ezinama-apula kanye namagilebhisi. Ukucwaninga okuvela eNyuvesi yaseCalifornia, uDavis, e-USA, kukhombisa ukuthi ukufafaza i-200ppm GA3 ngemuva kokuwa kwamaqabunga ebusika kunganciphisa isikhathi se-dollarmanch ngezinsuku ezingama-30-45. Ngo-2023, indawo ekhiqiza i-Dingxi Apple esifundazweni saseGessu yathola izihlahla ezincane ezingama-97,6% zezihlahla ezincane ngalowo nyaka nge- "Pre-Bud + Pre-Flomoling" Indlela yokufafaza kabili, ukukhuphuka kwama-82% ngaphezulu kokutshala kwendabuko.

3. "Isiteshi sokulawula" sokuqhakaza izimbali kanye nezithelo: Ukulawulwa okuqondile komjikelezo wokuphila kwezitshalo

Indlela ye-Gibberellic Acid (GA3) yokulawula izimbali iyinhle. Isikhungo sesayensi yezitshalo ye-Chinese Academy of China Academy of Agricultural Sciences etholakale ukuthi i-GA3 ne-Ethylene ibe nobudlelwano bokulingana okunamandla: Ukufafaza i-15ppm GA3 ngesikhathi sokunwebeka kwezithelo ze-citrus kungahlelela ngasikhathi sinye. Iphepha elishicilelwe kwi-Biology Yesitshalo nguGyeongju University eSouth Korea ngo-2023 likhomba ukuthi ngokufafaza i-GA3 nge-gradients (10ppm → 20ppm → 30ppm), isivuno esiqhubekayo sama-sitrobheli singanwetshwa ezinyangeni eziyi-9, futhi isivuno singandiswa ngezikhathi ezi-3.2.

I-4.

Ukubhekana nezinselelo zesimo sezulu esibi kakhulu, i-gibberellic acid (GA3) ikhombisile izinzuzo ezihlukile. Ngesikhathi sezimvula ezinamandla eHenan ngo-2023, ukhula uWang Jianguo wamukela "ukufafaza kwenhlekelele kwe-50ppm ga3 + i-post-faving faving ye-100ppm ga3" ukufezekisa isimangaliso sika-832 kg nge-MU. Idatha evela kwi-Institute of Plant Physiology of the Russian Academy of Science iveze ukuthi inkomba yokumelana nezimpande zamanzi ephathwe nge-GA3 ikhuphuke ku-8.7 (iqembu lokulawula lalingu-4,2), kanye nomthamo wokugcina wamanzi ngaphansi kwesomiso.

Ngokwesimo sokuvuselelwa kokusebenzisa i-Upgrading, i-Gibberellic Acid (GA3) isebenzisa kabusha i-COURCICTICT Product Valual Chain. Ngo-2023, izindawo zokukhiqiza ze-Hainan Mango zithole isilinganiso se-soshukela-acid kashukela we-18: 1 ngokusebenzisa "ukufafaza i-10ppm GA3 ngaphambi kokuqhakaza i-20ppm GA3 ngaphambi kokuvuna", ngesilinganiso se-premium esifinyelela ku-300%. Abatshali bamagilebhisi be-Chile basebenzisa ubuchwepheshe bokulawula okuqondile kwe-GA3 ukufezekisa ukufana kwezithelo ezingama-98.7%, ukuphindisela ngentengo yokuthumela ngaphandle.
