Enkambweni yokutshala utamatisi, sivame ukuhlangana nesimo sezinga eliphansi lokumisa izithelo kanye nokungabi nazithelo, kulokhu, akudingeki sikhathazeke ngakho, futhi singasebenzisa inani elifanele labalawuli bokukhula kwezitshalo ukuxazulula lolu chungechunge lwezinkinga.
1. I-Ethephon
Enye iwukunqanda ubuze. Ngenxa yokushisa okuphezulu, umswakama ophezulu kanye nokubambezeleka kokufakelwa kabusha noma ukufakwa kwekoloni ngesikhathi sokutshala izithombo, ukukhula kwezithombo kungalawulwa ngamaqabunga angama-300mg/kg we-ethethylene spray amaqabunga lapho amaqabunga ama-3, isikhungo esingu-1 namaqabunga eqiniso angu-5, ukuze izithombo ziqine, amaqabunga aqiniswe, iziqu zibe namandla, izimpande zokucindezeleka ziyakhula, izimpande ziyakhula, isivuno siyathuthukiswa. Ukugxila akufanele kube phezulu kakhulu noma kube phansi kakhulu.
Eyesibili eyokuvuthwa, kunezindlela ezi-3:
(1) I-Peduncle coating: Uma isithelo simhlophe futhi sivuthiwe, i-300mg/kg ye-ethephon isetshenziswa ku-inflorescence yesigaba sesibili se-peduncle, futhi ingaba bomvu futhi ivuthiwe 3 ~ 5d.
(2) Ukuhlanganiswa kwezithelo: 400mg/kg we-ethephon isetshenziswa kuma-sepals kanye nendawo yesithelo eseduze yembali emhlophe yezithelo ezivuthiwe, futhi ukuvuthwa okubomvu kungama-6-8d ngaphambili.
(3) Izithelo ze-Fruit Leaching: Izithelo zenkathi yokuguqulwa kombala ziqoqwa futhi zicwiliswe ku-2000-3000mg / kg isixazululo se-ethethylene se-10 kuya ku-30s, bese sikhishwa futhi sibekwe ku-25 ° C kanye nomswakama ohlobene nomoya 80% kuya ku-85% ukuze uvuthwe, futhi ungaphenduka ube bomvu, futhi, akufanele ufakwe ohlwini lwezithelo ezi-6 ezikhanyayo. njengalezo ezisesitshalweni.
2.I-Gibberellik acid
Ingaphromotha ukulungiselelwa kwesithelo. Isikhathi sokuqhakaza, 10 ~ 50mg/kg spray izimbali noma cwilisa izimbali izikhathi 1, ingavikela izimbali nezithelo, ukhuthaze ukukhula izithelo, ibhomu isithelo.
3. Polybulobuzole
Kungavimbela ize. Ukufafaza nge-150mg/kg ye-polybulobulozole ezitshalweni zikatamatisi ezinesigaba eside esingavundile kungalawula ukukhula okuyinyumba, kukhuthaze ukukhula kokuzala, kwenze kube lula ukuqhakaza nezithelo, kuqhubekisele phambili usuku lokuvuna, kwandise isivuno sokuqala kanye nomkhiqizo ophelele, futhi kunciphisa kakhulu inkomba yezifo kanye nenkomba yezifo eziwubhubhane kanye nezifo ezibangelwa amagciwane. Utamatisi okhula ngokungapheli welashwa nge-polybulobulozole isikhathi esifushane sokuvinjelwa futhi ungase uqalise ukukhula ngokushesha ngemva kokutshala, okwakusiza ukuqinisa isiqu kanye nokumelana nezifo.
Uma kunesidingo, ukulawulwa kwezimo eziphuthumayo kungenziwa entwasahlobo yisithombo sikatamatisi, lapho izithombo zisanda kuvela futhi izithombo kufanele zilawulwe, i-40mg/kg ifanelekile, futhi ukuhlushwa kungandiswa ngokufanele, futhi i-75mg/kg ifanele. Isikhathi esisebenzayo sokuvinjelwa kwe-polybulobuzole ekugxilweni okuthile cishe amasonto amathathu. Uma ukulawulwa kwezithombo kungaphezu kwamandla, i-100mg/kg ye-gibberellic acid ingafafazwa phezu kwamaqabunga bese kwengezwa umanyolo we-nitrogen ukuze unciphise.
Kungavimbela ize. Enkambweni yokutshalwa kwezithombo zikatamatisi, ngezinye izikhathi ngenxa yokushisa kwangaphandle kuphezulu kakhulu, umanyolo omningi, ukuminyana okuphezulu kakhulu, ukukhula okusheshayo nezinye izizathu ezibangelwa izithombo, ngaphezu kokutshala izithombo ezihlukene, ukulawula ukuchelela, ukuqinisa umoya, kungaba amaqabunga ama-3 ~ 4 ezinsukwini ezingu-7 ngaphambi kokutshala, nge-250 ~ 500mg yenhlabathi yokuvimbela ukukhula kwe-vegetarian / kg.
yisithombo Small, degree kancane oyinyumba, kungenziwa olufuthwe, kuze iqabunga yisithombo kanye Isiqu surface umfaniswano ngokuphelele embozwe amaconsi amahle ngaphandle degree ogelezayo; Uma izithombo zinkulu futhi izinga lokuzala linzima, zingafuthwa noma zithelwe.
Ngokuvamile 18 ~ 25℃, khetha izinsuku ngaphambi kwesikhathi, sekwephuzile noma eliguqubele ukuze uzisebenzise. Ngemuva kokufaka isicelo, ukungena komoya kufanele kuvinjelwe, umbhede obandayo kufanele umbozwe ngohlaka lwefasitela, indawo yokushisa kufanele ivalwe eshedini noma ivale iminyango kanye neWindows, ithuthukise izinga lokushisa lomoya futhi ikhuthaze ukumuncwa komuthi owuketshezi. Ungacheleli phakathi nosuku olu-1 ngemuva kokufakwa ukuze ugweme ukwehlisa ukusebenza kahle.
Ngeke isetshenziswe emini, futhi umphumela uqala 10d ngemva sishaye, futhi umphumela ingagcinwa for 20-30D. Uma izithombo zingabonakali isenzakalo esiyinyumba, kungcono ukuthi ungaphathi irayisi elifushane, ngisho noma izithombo zikatamatisi zide, inani lezikhathi zokusebenzisa irayisi elifushane akufanele libe liningi kakhulu, hhayi izikhathi ezingaphezu kwezingu-2 ezifanele.
