Ukusebenza kunye nemisebenzi yokusetyenziswa kweChlormequat chloride (CCC) kwizityalo ezikhulayo

I-Chlormequat chloride (CCC) ngumchasi we-gibberellins.Umsebenzi wayo oyintloko kukuthintela i-biosynthesis ye-gibberellins.Inokuthintela ukunyuswa kweeseli ngaphandle kokuchaphazela ukuhlukana kweeseli, inqanda ukukhula kweziqu kunye namaqabunga ngaphandle kokuchaphazela ukuphuhliswa kwezitho zesini, ngaloo ndlela ifezekisa ulawulo. yobude, ukuxhathisa indawo yokuhlala kunye nokwandisa isivuno.

Ke yintoni imisebenzi kunye nemisebenzi yeChlormequat chloride (CCC)? Ingasetyenziswa njani iChlormequat chloride (CCC) ngokuchanekileyo kwizityalo ezahlukeneyo? Yintoni esifanele sinikele ingqalelo kuyo xa sisebenzisa iChlormequat chloride (CCC)?

Ukusebenza kunye nemisebenzi yeChlormequat chloride(CCC)
(1) I-Chlormequat chloride (CCC) ikhulula umonakalo "wokutya ukushisa" kwimbewu.
I-Chlormequat chloride (CCC) isetyenziswa ekukhuleni kwerayisi.
Xa amaqondo obushushu embewu yerayisi egqitha ku 40°C ngaphezulu kweyure eziyi 12, zihlambe kuqala ngamanzi acocekileyo, uze ufunxe imbewu nge 250mg/LChlormequat chloride (CCC) engamanzi iiyure ezingama-48. Ulwelo kufuneka luntywilisele imbewu. Emva kokuhlamba isisombululo samayeza, ukuhluma kwi-30 ℃ kunokunciphisa ngokuyinxenye umonakalo owenziwe "kukutya ubushushu".

(2) I-Chlormequat chloride (CCC) ukuhlakulela izithole ezinamandla
I-Chlormequat chloride (CCC) isetyenziswa ekukhuliseni umbona.
Gxumisa imbewu ngesisombululo sekhemikhali se 0.3% ~ 0.5% ngeyure ezi 6, isisombululo:imbewu = 1:0.8, yomile kwaye uhlwayele, fafaza imbewu ngesisombululo se-2% ~ 3% seChlormequat chloride (CCC) yokufaka imbewu, kwaye uhlwayele i-12 iiyure. , kodwa izithole zomelele, inkqubo yeengcambu iphuhlisiwe, ama-tillers amaninzi, kwaye isivuno sanda malunga ne-12%.

Tfutha nge-0.15% ~ 0.25% isisombululo sekhemikhali kwinqanaba lokuqala lokuhlakula, kunye nomthamo wokutshiza we-50kg/667㎡ (uxinzelelo akufanele lube phezulu, kungenjalo intloko kunye nokuvuthwa kuya kulibaziseka), oko kunokwenza izithole zengqolowa zibe mfutshane. kwaye yomelele, yandise i-tillering, kwaye yandise isivuno nge-6.7% ~ 20.1%.

Nciphisa imbewu ngamaxesha angama-80 ukuya kuma-100 nge-50% yamanzi kwaye uwacwilise iiyure ezi-6. Kuyacetyiswa ukuba ucwilise imbewu ngolwelo. Yomisa emthunzini emva koko uhlwayele. Oku kuya kwenza izityalo zibe zifutshane kwaye zomelele, kunye neenkqubo zeengcambu eziphuhliswe kakuhle, amaqhina aphantsi, azikho iintloko, iindlebe ezinkulu kunye neengqolowa ezipheleleyo, kunye nokunyuka okukhulu kwesivuno. Kwinqanaba lokugalela, sebenzisa i-0.2% ~0.3% yesisombululo sekhemikhali kwaye utshize i-50kg yeChlormequat chloride (CCC) rhoqo kwi-667 square metres. Ingadlala indima ekugqumeni izithole, ukumelana netyuwa-alkali kunye nembalela, kwaye yandise isivuno malunga ne-20%.

(3) I-Chlormequat chloride (CCC) inqanda ukukhula kwesiqu kunye neqabunga, ixhathisa indawo yokulala, kwaye yandisa isivuno.
I-Chlormequat chloride (CCC) isetyenziswa ekukhuleni kwengqolowa.
Ukutshiza iChlormequat chloride (CCC) ekupheleni kwesixhobo sokuhlakula kunye nokuqala kokudityaniswa kunokuthintela ngokufanelekileyo ukwandiswa kwee-internodes zeendawo ezisezantsi ezi-1 ukuya kwezi-3 zesiqu, okuluncedo kakhulu ekuthinteleni ukufakwa kwengqolowa kunye nokunyusa izinga lendlebe. Ukuba i-1 000 ~ 2 000 mg / LChlormequat chloride (CCC) ifafazwe ngexesha lesigaba sokudibanisa, iya kuthintela i-elongation ye-internode kwaye ichaphazele nophuhliso oluqhelekileyo lweendlebe, okubangela ukunciphisa isivuno.
