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 ukutshintshwa okanye i-colonization ngexesha lokukhula kwezithole, ukukhula kwezithole kunokulawulwa ngu-300mg / kg ye-ethethylene amaqabunga e-spray xa amaqabunga ama-3, iziko eli-1 kunye namagqabi angama-5 okwenyaniso, ukwenzela ukuba izithole zomelele, amagqabi aqiniswe, iziqu ziqine, iingcambu zoxinzelelo zikhula, imveliso yoxinzelelo iyakhula, imveliso yoxinzelelo iyakhula, isivuno siyakhula. 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) Fruit leaching: Iziqhamo zexesha lokuguqulwa kombala ziqokelelwa kwaye zifakwe kwi-2000-3000mg / kg isisombululo se-ethethylene ye-10 ukuya kwi-30s, kwaye emva koko ikhutshwe kwaye ibekwe kwi-25 ° C kunye nomswakama womoya we-80% ukuya kwi-85% ukuya kwi-riper, kwaye inokujika ibe bomvu emva kwe-4, kodwa ifanele ifakwe kwi-6 iziqhamo ezikhanyayo. njengabo bakwisityalo.

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 i-polybulobulozole kwizithole zetumato ezinenqanaba elide elingazaliyo kunokulawula ukukhula okungazaliyo, kukhuthaze ukukhula kwenzala, kube lula ukudumba nokumila kweziqhamo, kuhambise phambili umhla wokuvuna, kwandise isivuno sakwangoko kunye nesiphumo esipheleleyo, kwaye kunciphisa ngokuphawulekayo isalathiso sezifo kunye nezifo eziqhambukayo kwangethuba kunye nezifo ezibangelwa ziintsholongwane. 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 obungaphandle buphezulu kakhulu, isichumisi esininzi, ukuxinana okuphezulu kakhulu, ukukhula ngokukhawuleza kunye nezinye izizathu ezibangelwa zizithole, ngaphezu kokutyalwa kwezithole, ukulawula ukunkcenkceshela, ukomeleza umoya, kunokuba yi-3 ~ 4 amaqabunga ukuya kwiintsuku ezisi-7 ngaphambi kokutyala, kunye ne-250 ~ 500mg ye-vegetarian / kg yokukhula komhlaba.
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 zingabonakali into enqabileyo, kungcono ukuba ungayiphathi irayisi emfutshane, nokuba izithole ze-tomato zide, inani lamaxesha okusebenzisa irayisi emfutshane akufanele libe lininzi, ukuba lingabi ngaphezu kwama-2 amaxesha afanelekileyo.
