Ukusetshenziswa kwezilawuli zokukhula kwezitshalo ezihlahleni zezithelo - Litchi

Isigaba 1:Izinyathelo zobuchwepheshe zokulawula amahlumela nokukhuthaza izimbali.

Umgomo wokulawula ukuhluma kwe-lychee kanye nokuqhakanjiswa kwezimbali ukuthi ngokwezidingo zenkathi yokuhlukaniswa kwezimbali zezinhlobo ezahlukahlukene, amahlumela kufanele aphonswe izikhathi ezi-2 kuya kwezi-3 ngesikhathi esifanele ngemuva kokuvuna, futhi amahlumela asebusika angalawuleka. thuthukisa imiqumbe yezimbali ngemva kokuba amahlumela asekwindla okugcina ephenduka abe luhlaza noma avuthiwe.
izinyathelo zokuphatha ezihlukene.

Ukusetshenziswa kwezilawuli zokukhula kwezitshalo kungalawula ngempumelelo ukuhluma kwamahlumela asebusika e-litchi, kukhuthaze ukuqhakaza, kukhuphule izinga lokuqhakaza kanye nenani lezimbali zabesifazane, kuhlakulele ama-spikes ezimbali aqinile, futhi kubeke isisekelo esihle sezinto zokuqhakaza nokuthela ngonyaka olandelayo. .
​
1.Naphthalene acetic acid(NAA)
2.Paclobutrazol(Paclo)

(1)I-Naphthalene acetic acid(NAA)
Uma i-lychee ikhula ngamandla futhi ingahlukani nezimbali, sebenzisa isisombululo se-Naphthalene acetic acid (NAA) esingama-200 kuya ku-400 mg (NAA) ufafaze esihlahleni sonke ukuvimbela ukukhula kwamahlumela amasha, ukwandisa inani lamagatsha ezimbali futhi ukwandisa isivuno sezithelo. .

(2) I-Paclobutrazol (Paclo)
Sebenzisa impushana emanzi engu-5000mg/L Paclobutrazol (Paclo) ufafaze amahlumela asebusika asanda kukhangwa, noma gcoba i-paclobutrazol enhlabathini ezinsukwini ezingu-20 ngaphambi kokuba amahlumela asebusika aqhume, 4g isitshalo ngasinye, ukuze uvimbele ukukhula kwamahlumela asebusika futhi unciphise inani lamahlumela. amahlamvu. ukwenza umqhele uhlangane, uthuthukise isihloko nokuqhakaza, futhi ukhulise ingxenye yezimbali zesifazane.

Isigaba 2: Vimbela ukushesha kwamathiphu
Ngemuva kokuthi "amahlumela" e-flower spike, ama-flower buds azoncipha futhi awe, izinga le-spike lizoncishiswa, futhi lingase liphenduke libe amagatsha emifino ngokuphelele.
"Ukudubula" kwe-Litchi kuzobangela ukuncishiswa kwesivuno kumazinga ahlukahlukene, noma ngisho kungabikho sivuno, futhi sekube esinye sezizathu ezibalulekile zokuhluleka kokuvuna i-lychee.

1. I-Ethephon 2.Paclobutrazol(Paclo)
(1)I-Ethephon
Ezihlahleni ze-lychee ezinama-spikes ezimbali ezinzima namaqabunga, ungafafaza u-40% we-ethephon 10 kuya ku-13 mL kanye no-50 kg wamanzi kuze kube yilapho iqabunga limanzi ngaphandle koketshezi oluconsayo ukuze ubulale amapheshana futhi ukhuthaze ukukhula kwezimbali.

Uma usebenzisa i-ethephon ukubulala amaqabunga amancane, ukugxila kufanele kulawulwe.Uma kuphezulu kakhulu, kuzolimaza kalula ama-spikes ezimbali.
Uma iphansi kakhulu, umphumela ngeke ube muhle. Sebenzisa ukugxila okuphansi uma izinga lokushisa liphezulu.

(2)I-Paclobutrazol(Paclo) ne-Ethephon
Phatha isihlahla se-litchi esineminyaka engu-6 nge-1000 mg/L Paclobutrazol (Paclo) kanye ne-800 mg/L Ethephon phakathi no-November, bese usiphatha futhi ngemva kwezinsuku eziyi-10, okwenza ngcono kakhulu izinga lokuqhakaza kwezitshalo. .

Isigaba 3 : Ukulondoloza Izimbali Nezithelo
I-Lychee buds iyawa ngaphambi kokuqhakaza. Izimbali zesifazane zama-lychees zingase ziwe ngokwengxenye ngenxa yokuntuleka kokuvundiswa noma ukuvundiswa okuncane kwempova nokuvundiswa, futhi ngokwengxenye ngenxa yokungatholakali kwezakhi ezanele. Izimbali zesifazane kuphela ezinempova enhle nokuvundiswa kanye nokudla okwanele zingakhula zibe izithelo.

Izinyathelo Zobuchwepheshe Zokulondoloza Izimbali Nezithelo
(1)I-Gibberellic acid(GA3) noma i-Naphthalene acetic acid(NAA)
Sebenzisa i-gibberellin ekuhlanganiseni kuka-20 mg/L noma i-Naphthalene acetic acid (NAA) ekuhlanganiseni kuka-40 kuya ku-100 mg/L ezinsukwini ezingu-30 ngemva kokunyamalala kwezimbali ze-lychee.
Ukufafaza ngesixazululo kunganciphisa nokwehla kwezithelo, kukhuphule izinga lokumiswa kwezithelo, kukhuphule usayizi wezithelo, futhi kwandise isivuno. I-30-50mg/L I-Gibberellic acid (GA3) inganciphisa ukwehla kwesithelo se-physiological yaphakathi nethemu, kuyilapho i-30-40mg/L i-Naphthalene acetic acid (NAA) inomphumela othile ekwehliseni ukwehla kwesithelo sangaphambi kokuvuna.

(2)I-Ethephon
Sebenzisa i-Ethephon engu-200~400mg/L ngesikhathi sokuhluma (okungukuthi ekuqaleni kuka-March)
Isixazululo singafafazwa esihlahleni sonke, esinomthelela omuhle wokunciphisa izimbali, ukuphinda kabili inani lezithelo, ukwandisa isivuno ngamaphesenti angaphezu kuka-40, futhi kuguqule isimo sezimbali eziningi ze-lychee nezithelo ezincane.
