Izilawuli zokukhula kwezityalo zisebenzisa kwi lettuce

1. Ukophula imbewu yokulala
Elona qondo lobushushu lokuntshula kwembewu ye lettuce yi 15-29℃. Ngaphezulu kwe-25℃, amandla okuntshula ancitshiswa kakhulu phantsi kweemeko ezingakhanyiyo. Imbewu ephula i-dormancy inokuphucula ukuntshula kwayo phantsi kobushushu obuphezulu. Xa ubushushu bomhlaba bufikelela ku 27℃, imbewu ye lettuce ikholisa ukuhendelwa ukuba ilale.

Thiourea
Unyango nge-0.2% ye-Thiourea ibangele izinga lokuntshula lama-75%, ngelixa ulawulo lwaluyi-7% kuphela.

I-Gibberellic Acid GA3
Unyango nge-Gibberellic Acid GA3 100mg/L isisombululo kukhokelele ekuntshuleni okumalunga nama-80%.

IKinetin
Ukucwiliswa kwembewu nge-100mg/L isisombululo se-kinetin se-3min kunokoyisa i-dormancy phantsi kobushushu obuphezulu. Xa ubushushu bufikelela kwi-35 ℃, isiphumo se-kinetin sibaluleke kakhulu.

2: Thintela ukubholitha
Daminozide
Xa i-lettuce iqala ukukhula, fafaza izityalo nge-4000-8000mg / L i-Daminozide ngamaxesha angama-2-3, kanye emva kweentsuku ezi-3-5, ezinokuthi zithintele kakhulu i-bolting, ukwandisa ubukhulu beziqu, kunye nokuphucula ixabiso lezorhwebo.

I-Maleic hydrazide
Ngexesha lokukhula kwezithole ze lettuce, unyango nge-Maleic hydrazide 100mg/L isisombululo sinokunqanda ukugquma nokudubula.

3: Khuthaza ukufaka iibholiti
I-Gibberellic Acid GA3
I-Lettuce kuphela kweqabunga kunye nemifuno yeengcambu ezinokukhuthaza ukubopha phantsi kweemeko ezifudumele kunye neentsuku ezinde ngenxa yokungeniswa kobushushu obuphezulu bokuhlukana kweentyatyambo. Ukunyanga imbewu ngeentsuku ezinde kunye nobushushu obuphantsi kunokukhuthaza ukumila kweentyatyambo, kodwa ukugcinwa kwembewu kufuna imozulu epholileyo. Ngokomzekelo, kuvavanyo lwegumbi lemozulu eyenziweyo, ngaphakathi kwe-10-25 ℃, zombini iintsuku ezimfutshane kunye neentsuku ezinde zinokuqhafaza kwaye ziqhakaze; ngaphantsi kwe-10-15℃ okanye ngaphezulu kwe-25℃, isiqhamo sibi kwaye nogcino lwembewu luyacutheka; ngokuchaseneyo, uvimba wembewu ngowona mkhulu kwi-10-15℃. Kunzima ukugcina imbewu ye lettuce, kwaye ukutshiza iGibberellic Acid GA3 kungakhuthaza ukubolthwa kwe lettuce kwaye kunciphise ukubola.

I-Gibberellic Acid GA3
Xa i-lettuce yekhaphetshu inamagqabi angama-4-10, ukutshiza i-5-10mg /L isisombululo se-Gibberellic Acid GA3 sinokukhuthaza ukugquma kunye neentyantyambo ze-lettuce yekhaphetshu ngaphambi kwekhaphetshu, kwaye imbewu ivuthwe iintsuku ezili-15 ngaphambili, ukwandisa isivuno sembewu.

4 Khuthaza ukukhula
I-Gibberellic Acid GA3
Elona qondo lobushushu kwizithole ze lettuce liphakathi kwe 16-20℃, kwaye elona qondo lobushushu liphezulu kwi 18-22℃. Ukuba iqondo lobushushu lingaphezulu kwe 25℃, iletisi iyakukhula ngokulula kakhulu. Ukukhanya kwi-greenhouses kunye ne-sheds ebusika nasentwasahlobo kunokuhlangabezana nokukhula okuqhelekileyo kwe-lettuce. Amanzi kufuneka alawulwe ngexesha lokumisela okuqhubekayo, kwaye amanzi aneleyo kufuneka anikezwe ngexesha lesihloko. Kwi-lettuce eneziqu zethenda ezidliwayo, xa isityalo sinamagqabi angama-10-15, fafaza nge-10-40mg/L yegibberellin.

Emva kokonyango, ukuhlukana kwamagqabi entliziyo kuyakhawuleza, inani lamagqabi landa, kwaye iziqu zethenda zikhawuleza ukuba zinde. Inokuvunwa kwiintsuku ezili-10 ngaphambili, inyusa isivuno nge-12% -44.8%. I-lettuce yeqabunga iphathwa nge-10mg /L ye-gibberellin iintsuku eziyi-10-15 ngaphambi kokuvuna, kwaye isityalo sikhula ngokukhawuleza, esinokunyusa isivuno nge-10% -15%. Xa usebenzisa i-gibberellins kwi-lettuce, ingqwalasela kufuneka ihlawulwe kwingqwalasela esetyenziselwa ukuphepha ukutshiza i-concentration ephezulu kakhulu, eya kukhokelela kwiziqu ezinqabileyo, ukunciphisa ubunzima obutsha, i-lignification kwinqanaba elilandelayo, kunye nokunciphisa umgangatho.

Kwakhona kuyimfuneko ukuphepha ukutshiza xa izithole zincinci kakhulu, ngaphandle koko iziqu ziya kuba zincinci, i-bolting iya kwenzeka kwangaphambili, kwaye ixabiso lezoqoqosho liya kulahleka.

I-DA-6 (i-Diethyl aminoethyl hexanoate)
Ukutshiza i-lettuce nge-10mg/L ye-DA-6 (i-Diethyl aminoethyl hexanoate) isisombululo kunokwenza ukuba izithole zibe nenkqubo yeengcambu eziphuhlileyo kunye neziqu ezityebileyo, ngokubanzi ukwandisa imveliso ngama-25% -30%.

5. Ukugcinwa kweekhemikhali
I-6-Benzylaminopurine (6-BA)
Njengoninzi lwemifuno, i-lettuce senescence kukujika kwamagqabi abe tyheli ngokuthe ngcembe emva kokuvuna, okulandelwa kukuqhekeka kancinci kwezicubu, zincangathi kwaye zibole. Ukutshiza intsimi nge-5-10mg/L 6-Benzylaminopurine (6-BA) phambi kokuvuna kunokwandisa ixesha lokuba i-lettuce ihlale iluhlaza emva kokupakishwa ngeentsuku ezi-3-5. Unyango nge 6-BA emva kokuvuna nako kunokulibazisa ukuvuthwa. Ukutshiza i-lettuce nge-2.5-10 mg/L 6-BA 1 imini emva kokuvuna kunomphumo omhle. Ukuba i-lettuce igcinwa kuqala kwi-4 ° C kwiintsuku ezingama-2-8, emva koko ifafazwe nge-5 mg / L 6-BA kumagqabi kwaye igcinwe kwi-21 ° C, emva kweentsuku ezi-5 zonyango, kuphela i-12.1% yolawulo. inokuthengiswa, ngelixa i-70% yonyango inokuthengiswa.

Daminozide
Ukucwiliswa kwamagqabi kunye ne-lettuce iziqu kunye ne-120 mg / L isisombululo se-Daminozide sinesiphumo esihle sokugcina kwaye sandisa ixesha lokugcina.

I-Chlormequat Chloride (CCC)
Ukucwiliswa kwamagqabi kunye neziqu ze-lettuce kunye ne-60 mg / L isisombululo se-Chlormequat Chloride (CCC) sinesiphumo esihle sokugcina kwaye sandisa ixesha lokugcina.
