Ukusetyenziswa kokulawula ukukhula kwezityalo kwimithi yeziqhamo - Litchi

Icandelo 1:Amanyathelo obuchule okulawula amahlumela kunye nokukhuthaza iintyatyambo.

Umgaqo wokulawula ukuhluma kwe-lychee kunye nokukhuthaza ukuhluma kweentyatyambo kukuba ngokweemfuno zexesha lokwahlulahlula iintyatyambo zeentlobo ezahlukeneyo, amahlumela kufuneka ampontshwe amaxesha ama-2 ukuya kwe-3 ngexesha elifanelekileyo emva kokuvuna, kwaye amahlumela asebusika angalawulwa. khuthaza iintyatyambo emva kokuba amahlumela ekwindla yokugqibela ajike abe luhlaza okanye aqolileyo.
amanyathelo ahlukeneyo olawulo.

Ukusetyenziswa kwezilawuli zokukhula kwezityalo kunokulawula ngempumelelo ukuntshula kwamahlumelo ebusika e-litchi, kukhuthaze ukudumba kweentyatyambo, ukunyusa izinga leentyatyambo kunye nomlinganiselo weentyatyambo ezibhinqileyo, ukulima izikhonkwane zentyatyambo ezomeleleyo, kwaye kubeke isiseko esilungileyo sezinto zokudumba kunye neziqhamo kunyaka olandelayo.​
​
1.Naphthalene acetic acid(NAA)
2.Paclobutrazol(Paclo)

(1)Naphthalene acetic acid(NAA)
Xa i-lychee ikhula ngamandla kwaye ingahlukanisi kwiintyatyambo, sebenzisa i-200 ukuya ku-400 mg /L isisombululo seNaphthalene acetic acid (NAA) ukutshiza kuwo wonke umthi ukuvimbela ukukhula kwamahlumela amatsha, ukwandisa inani lamasebe entyatyambo kunye ukwandisa isivuno seziqhamo.​

(2) iPaclobutrazol (Paclo)
Sebenzisa i-5000mg / L Paclobutrazol (Paclo) umgubo omanzi ukutshiza amahlumela asebusika asanda kutsalwa, okanye usebenzise i-paclobutrazol emhlabeni iintsuku ezingama-20 ngaphambi kokuba amahlumela asebusika ahlume, i-4g kwisityalo ngasinye, ukuthintela ukukhula kwamahlumela asebusika kunye nokunciphisa inani leentyatyambo. amagqabi. ukwenza isithsaba sibambene, ukukhuthaza isihloko kunye neentyatyambo, kunye nokwandisa umlinganiselo weentyatyambo zasetyhini.

Icandelo lesi-2: Thintela ukungxama kweengcebiso
Emva kokuba "amahlumela" entyatyambo, iintyatyambo ezenziweyo ziya kuncipha kwaye ziwe, isantya se-spike siya kuncitshiswa, kwaye sinokuguquka ngokupheleleyo sibe ngamasebe ezityalo.
I-Litchi "yokudubula" iya kubangela ukucuthwa kwesivuno ukuya kumaqondo ahlukeneyo, okanye nokuba akukho sivuno, kwaye ibe sesinye sezizathu ezibalulekileyo zokungaphumeleli kokuvuna i-lychee.

1. Ethephon 2.Paclobutrazol(Paclo)
(1)Ethephon
Kwimithi ye-lychee enezikhonkwane zentyatyambo kunye namagqabi, unokutshiza i-40% ethephon 10 ukuya kwi-13 mL kunye ne-50 kg yamanzi de umphezulu wegqabi ufume ngaphandle kokuvuza ulwelo ukubulala amaphecana kunye nokukhuthaza ukukhula kwentyatyambo.

Xa usebenzisa i-ethephon ukubulala amaqabunga amancinci, ukugxininiswa kufuneka kulawulwe.Ukuba kuphezulu kakhulu, kuya kulimaza ngokulula i-spikes yeentyatyambo.
Ukuba iphantsi kakhulu, umphumo awuyi kuba mhle. Sebenzisa ugxininiso oluphantsi xa ubushushu buphezulu.

(2) I-Paclobutrazol (Paclo) kunye ne-Ethephon
Nyanga umthi we-litchi oneminyaka emi-6 nge-1000 mg/L Paclobutrazol (Paclo) kunye ne-800 mg/L Ethephon phakathi kuNovemba, uze uwuphathe kwakhona emva kweentsuku ezili-10, nto leyo ephucula kakhulu izinga leentyantyambo zezityalo. .

Icandelo lesi-3 :Ukugcina iintyatyambo kunye neZiqhamo
I-Lychee buds iyawa ngaphambi kokuba iqhakaze. Iintyatyambo zasetyhini ze-lychees zinokuwa ngokuyinxenye ngenxa yokunqongophala kokuchumisa okanye ukuvuthwa kakubi kunye nokuchumisa, kwaye ngokuyinxenye ngenxa yokungonelanga kwesondlo. Kuphela ziintyatyambo ezizimazi ezinokudluliselwa kakuhle kwe-pollination kunye nokuchumisa kunye nesondlo esaneleyo ezinokukhula zibe ziziqhamo.

Amanyathelo oBuchwephesha okugcina iintyatyambo kunye neziqhamo
(1)Gibberellic acid(GA3) okanye iNaphthalene acetic acid(NAA)
Sebenzisa i-gibberellin kwi-concentration ye-20 mg / L okanye i-Naphthalene acetic acid (NAA) kwi-concentration ye-40 ukuya kwi-100 mg / L iintsuku ezingama-30 emva kokuba iintyatyambo ze-lychee ziphelile.
Ukutshiza ngesisombululo nako kunokunciphisa ukuhla kweziqhamo, ukonyusa izinga lokumiselwa kweziqhamo, kwandise ubungakanani beziqhamo, kwaye kwandise isivuno. I-30-50mg/L i-Gibberellic acid (GA3) inokunciphisa i-mid-term physiological fruit drop, ngelixa i-30-40mg/L i-Naphthalene acetic acid (NAA) inefuthe elithile ekunciphiseni ukuhla kweziqhamo zangaphambi kokuvunwa.

(2)Ethephon
Sebenzisa 200 ~ 400mg/L Ethephon ngexesha lokuhluma (okt ekuqaleni ukuya phakathi kuMatshi)
Isisombululo sinokutshizwa kuwo wonke umthi, onesiphumo esihle sokuphungula iintyatyambo, ukuphindaphinda inani leziqhamo, ukwandisa isivuno ngaphezu kwe-40%, kunye nokutshintsha imeko yeentyatyambo ezininzi ze-lychee kunye neziqhamo ezincinci.
