Xa utyala iitumato, ezi zilawuli zine zokukhula kwezityalo zinokukhuthaza ngokufanelekileyo ukusetwa kweziqhamo zetomato kwaye zithintele ukungabi nasiqhamo

Kwinkqubo yokutyala iitumato, sihlala sidibana nemeko yezinga eliphantsi lokumisela iziqhamo kunye nokungabi nasiqhamo, kulo mzekelo, asifanele sikhathazeke ngayo, kwaye sinokusebenzisa umlinganiselo ofanelekileyo wabalawuli bokukhula kwezityalo ukusombulula olu luhlu lweengxaki. .

1. I-Ethephon

Enye kukuthintela okuphuthileyo.Ngenxa yobushushu obuphezulu, umswakama ophezulu kunye nokulibaziseka kokutshintshwa okanye i-colonization ngexesha lokulinywa kwezithole, ukukhula kwezithole kunokulawulwa ngu-300mg / kg we-ethethylene spray amaqabunga xa amaqabunga ama-3, i-1 yeziko kunye namagqabi angama-5 okwenyaniso, ukwenzela ukuba izithole zomelele, amagqabi. ziqinisiwe, iziqu zomelele, iingcambu ziyaphuhliswa, ukuxhathisa koxinzelelo kuphuculwe, kwaye isivuno sangethuba sandiswa.Ukugxininiswa akufanele kube phezulu okanye kuphantsi kakhulu.

Eyesibini yeyokuvuthwa, kukho iindlela ezi-3:
(1) Ukugquma kwePeduncle: Xa isiqhamo simhlophe kwaye sivuthiwe, i-300mg / kg ye-ethephon isetyenziswa kwi-inflorescence yecandelo lesibini le-peduncle, kwaye ingaba bomvu kwaye ivuthiwe 3 ~ 5d.
(2) Ukugquma kweziqhamo: I-400mg/kg ye-ethephon isetyenziswa kwi-sepals kunye nomphezulu okufutshane wesiqhamo sentyatyambo emhlophe evuthiweyo, kwaye ukuvuthwa okubomvu ku-6-8d ngaphambili.
(3) Iziqhamo zokucoca: Iziqhamo zexesha lokuguqulwa kombala ziqokelelwa kwaye zifakwe kwi-2000-3000mg / kg isisombululo se-ethethylene kwi-10 ukuya kwi-30s, kwaye emva koko ikhutshwe kwaye ibekwe kwi-25 ° C kunye nomswakama ohambelana nomoya yi-80% ukuya kwi-85. % ukuvuthwa, kwaye zinokujika zibebomvu emva kwe-4 ukuya kwi-6d, kwaye kufuneka zidweliswe ngexesha, kodwa iziqhamo ezivuthiweyo aziqaqambi njengezo zikwisityalo.

2.Gibberellik acid

Inokukhuthaza ukumiselwa kweziqhamo.Ixesha leentyatyambo, i-10 ~ 50mg/kg iintyatyambo zokutshiza okanye ukudipha iintyatyambo amaxesha angama-1, inokukhusela iintyatyambo kunye neziqhamo, ukukhuthaza ukukhula kweziqhamo, indawo yokuhlala ibhombu.

3. Polybulobuzole

Inokuthintela ilize.Ukutshiza i-150mg/kg ye-polybulobulozole kwizithole zetumamato ezineqonga elide elingazaliyo kunokulawula ukukhula okungazaliyo, kukhuthaze ukukhula kwenzala, kuququzelele ukudumba kweziqhamo nokumila kweziqhamo, kuhambise phambili umhla wokuvuna, kwandise isivuno sakwangoko kunye nesiphumo esipheleleyo, kwaye kunciphisa ngokubonakalayo isalathiso sezifo nezifo. iindyikityha zakuqala kunye nezifo zentsholongwane.Itumato yokukhula engapheliyo yanyangwa nge-polybulobulozole ixeshana elifutshane lokunqanda kwaye yakwazi ukuphinda ikhule kamsinya nje emva kokutyala, nto leyo eyayinceda ekomelezeni isikhondo nokuxhathisa izifo.

Xa kuyimfuneko, ulawulo olungxamisekileyo lunokwenziwa kwi-spring tomato seedling, xa izithole zisanda kuvela kwaye izithole kufuneka zilawulwe, i-40mg / kg ifanelekile, kwaye ukugxininiswa kunokunyuswa ngokufanelekileyo, kwaye i-75mg / kg ifanelekile.Ixesha elisebenzayo lokuvinjelwa kwe-polybulobuzole ekugxininiseni okuthile malunga neeveki ezintathu.Ukuba ulawulo lwezithole lugqithisile, i-100mg/kg yegibberellic acid ingatshizwa kumphezulu wamagqabi kwaye kugalelwe nesichumiso senitrogen ukuyikhulula.

4.I-Chlormequat chloride

Inokuthintela ilize.Kwinkqubo yokulima i-tomato izithole, ngamanye amaxesha ngenxa yobushushu bangaphandle buphezulu kakhulu, isichumisi kakhulu, ukuxinana okuphezulu kakhulu, ukukhula ngokukhawuleza kunye nezinye izizathu ezibangelwa izithole, ngaphezu kokutyala izithole, ukulawula ukunkcenkceshela, ukomeleza umoya, unako. Yiba 3 ~ 4 amagqabi ukuya kwiintsuku ezisi-7 phambi kokutyala, kunye ne-250 ~ 500mg/kg yokunkcenkceshela komhlaba omfutshane wemifuno, ukuthintela ukukhula.
Isithole esincinci, iqondo elincinci lokungazali, linokutshizwa, kwigqabi lezithole kunye nesiqu sesiqu salo sigqunywe ngamathontsi acolekileyo ngaphandle kokuqukuqela;Ukuba izithole zinkulu kwaye iqondo lokungazali linzima, zinokutshizwa okanye zigalelwe.

Ngokubanzi 18 ~ 25℃, khetha kwangethuba, kade okanye iintsuku ezinamafu ukuze uzisebenzise.Emva kokufaka isicelo, ukungena komoya kufuneka kuvinjelwe, ibhedi ebandayo kufuneka ifakwe kwisakhelo sefestile, i-greenhouse kufuneka ivalwe kwi-shed okanye ivale iingcango kunye neWindows, iphucule ubushushu bomoya kwaye ikhuthaze ukufunxa iyeza lamanzi.Musa ukunkcenkceshela ngosuku olu-1 emva kwesicelo ukuphepha ukunciphisa ukusebenza kakuhle.
Ayinakusetyenziswa emini, kwaye umphumo uqala i-10d emva kokutshiza, kwaye umphumo unokugcinwa kwi-20-30D.Ukuba izithole azibonakali isiganeko esiludlolo, kungcono ukuba ungayiphathi irayisi emfutshane, nokuba izithole ze-tomato zide, inani lamaxesha okusebenzisa irayisi emfutshane akufanele libe kakhulu, ukuba lingabi ngaphezu kwe-2 amaxesha afanelekileyo. .
