Ukusetshenziswa

1. Khuthaza ukwakheka kwezithelo ezithela izithelo ezingenambewu.Ngesikhathi sokuqhakaza kwamakhukhamba, fafaza isisombululo esingu-50-100mg/kg kanye ukuze ukhuthaze ukuthela kanye nokwanda kwesivuno.Ngemva kwezinsuku ezingu-7-10 zokuqhakaza kwamagilebhisi, i-rose iphunga elimnandi lifafazwa ngoketshezi oluyi-200-500mg/kg kanye ukuze kuthuthukiswe ukwakheka kwezithelo ezingenambewu.

2. Khuthaza ukukhula okunomsoco kwesilimo esidliwayo esinamagatsha anamanzi.Fafaza amaqabunga ngesisombululo se-50-100mg/kg kanye amasonto amabili ngaphambi kokuvuna;Ukufafaza amaqabunga esipinashi izikhathi ezi-1-2 amasonto amathathu ngaphambi kokuvuna kungandisa isiqu namaqabunga.

3. Phula i-dormancy futhi ukhuthaze ukuhluma kwamazambane.Gcoba izilimo eziyizigaxa kusixazululo esingu-0.5-1mg/kg imizuzu engama-30 ngaphambi kokuhlwanyela;Ukucwilisa imbewu yebhali ngo-1mg/kg wekhambi lomuthi ngaphambi kokuhlwanyela kungakhuthaza ukuhluma.

4. Imiphumela yokulwa nokuguga nokulondoloza: Gxilisa isisekelo samahlumela kagalikhi ngesixazululo esingu-50mg/kg imizuzu eyi-10-30, fafaza izithelo ngesixazululo esingu-5-15mg/kg kanye ngesikhathi sesigaba sesithelo esiluhlaza sewolintshi, cwilisa izithelo ngo-10mg/ isixazululo se-kg ngemva kokuvuna ubhanana, bese ufutha izithelo ngesixazululo esingu-10-50mg/kg ngaphambi kokuvunwa kwekhukhamba nekhabe, konke okungaba nomthelela wokulondoloza.

5. Ngesikhathi se-vernalization ye-chrysanthemums eqhakaza, ukufafaza amaqabunga nge-1000mg/kg yesisombululo somuthi, futhi ngesikhathi sokuhluma kwe-Cyclamen persicum, ukufafaza izimbali nge-1-5mg/kg yesisombululo somuthi kungakhuthaza ukuqhakaza.

6. Ukwenza ngcono izinga lokumiswa kwembewu ekukhiqizeni irayisi le-Hybrid ngokuvamile kuqala lapho umzali wesifazane efika ku-15%, futhi iphathwa nge-25-55mg/kg liquid spray izikhathi ezingu-1-3 ekupheleni kwesihloko esingu-25%.Okokuqala sebenzisa ukugxila okuphansi, bese usebenzisa ukugxila okuphezulu.

Izinyathelo zokuzivikela

1. I-Gibberellic acid inokuncibilika okuphansi kwamanzi.Ngaphambi kokusetshenziswa, yihlakaze ngenani elincane lotshwala noma i-Baijiu, bese ufaka amanzi ukuze uhlanjululwe ekugxiliseni okudingekayo.

2. Izitshalo eziphathwa nge-gibberellic acid zinokwanda kwembewu engavundile, ngakho-ke akufanelekile ukusebenzisa izibulala-zinambuzane ensimini.
