GA3, Gibberellin 90% TC gibberellic acid, ukulawulwa kokukhula kwezityalo, agrochemical 10%SP 20%SP
Intshayelelo
I-Gibberellin GA3 yeyona nto isetyenziswa kakhulu ukulawula ukukhula kwezityalo kwezolimo, amahlathi kunye nokulima kwezityalo e-China.
Imisebenzi ye-physiological ye-gibberellin GA3 ikakhulu ibandakanya: ukutshintsha umyinge weentyantyambo ezizimazi kunye nezenkunzi kwezinye izityalo, ukukhuthaza i-parthenocarpy, ukukhawulezisa ukukhula kweziqhamo kunye nokukhuthaza ukumiselwa kweziqhamo;Ukophula ukungabikho kokulala kwembewu, ukuntshula kwembewu kwangoko, ukukhawulezisa ukomelela kwesikhondo kunye nokufunxa ezinye izityalo;Ukwandisa indawo yeqabunga kunye nokukhawulezisa ukukhula kwamasebe amancinci kuhambelana nokuqokelela kwe-metabolites kwi-phloem kwaye kusebenze i-cambium;Ukuthintela ukuvuthwa kunye ne-senescence, lawula i-lateral bud dormancy kunye nokwakheka kwe-tuber.

Isicelo
2.1 Ukuze ufumane isiphumo?
Umsebenzi obalaseleyo we-gibberellin kukukhawulezisa ukunyuswa kweeseli (i-gibberellin inokunyusa umxholo we-auxin kwizityalo, kwaye i-auxin ilawula ngokuthe ngqo ukunyuswa kweeseli).Ikwakhuthaza ukwahlukana kweeseli.Inokukhuthaza ukwanda kweeseli (kodwa ayibangeli i-asidi yodonga lweseli).Ukongeza, i-gibberellin inokuthintela ukuvuthwa, i-lateral bud dormancy kunye nokuguga, umsebenzi wePhysiological of tuber formation.
2.2 Iza kusetyenziswa kweziphi izityalo?
I-Gibberellin ifanelekile kwizityalo ezilandelayo: ikotoni, i-tomato, iitapile, umthi weziqhamo, irayisi, ingqolowa, i-soya kunye necuba ukukhuthaza ukukhula kwazo, ukuhluma, ukuqhakaza kunye neziqhamo;Inokukhuthaza ukukhula kweziqhamo, iphucule izinga lokumisela imbewu, kwaye ibe nesiphumo esikhulayo somqhaphu, imifuno, imelon kunye neziqhamo, irayisi, isichumiso esiluhlaza, njl.
2.3 Umthamo kunye nokusetyenziswa
| Uqulunqo | Amagama ezityalo | Lawula into | Umthamo | Indlela yokusebenzisa |
| I-10% ye-TB | irayisi | Lawula ukukhula | 150-225 g/ha | Isitshizi samagqabi |
| isileri | Lawula ukukhula | 1500-2000 amaxesha ulwelo | tshiza | |
| 10% SP | isileri | Lawula ukukhula | 900-1000 amaxesha ulwelo | tshiza |
| Umthi wesitrasi | Lawula ukukhula | 5000-7500 amaxesha ulwelo | tshiza | |
| 20% SP | irayisi | Lawula ukukhula | 300-450 g/ha | Ukutshiza ngomphunga kunye namagqabi |
| iidiliya | Lawula ukukhula | 30000-37000 amaxesha ulwelo (pre anthesis);10000-13000 amaxesha ulwelo (emva kwe-anthesis) | tshiza | |
| ipoplar | Nqanda ukumila kweentyatyambo | 1.5-2 g / umngxuma | Isitofu somboko |
Amanqaku
1. I-gibberellic acid incinci kwi-solubility yamanzi, inyibilika ngotywala obuncinci okanye i-Baijiu ngaphambi kokusetyenziswa kwaye uyihlambulule kwi-concentration oyifunayo.
2. Imbewu eyinyumba yezityalo ephathwa nge-gibberellic acid iyanda, ngoko ayifanelekanga ukusebenzisa iyeza kwintsimi egciniweyo.
