Ukwethulwa kwe-CPPU
I-Forchlorfenuron ibizwa nangokuthi i-CPPU.I-CAS NO.ithi 68157-60-8.
I-Chlorophenylurea kusilawuli sokukhula kwezitshalo (CPPU kusilawuli sokukhula kwezitshalo) ingakhuthaza ukuhlukaniswa kwamaseli, ukwakheka kwezitho kanye nokuhlanganiswa kwamaprotheni.Ingabuye ithuthukise i-photosynthesis futhi ivimbele ukuhushulwa kwezithelo nezimbali, ngaleyo ndlela ikhuthaze ukukhula kwezitshalo, ukuvuthwa kwangaphambi kwesikhathi, ibambezele ukuvela kwamaqabunga esigabeni sakamuva sezitshalo nokwandisa isivuno.
Imisebenzi esemqoka ye-CPPU imi kanje:
1. Khuthaza ukukhula kwesiqu, amaqabunga, impande nesithelo.Uma isetshenziswa ekutshaleni ugwayi, ingenza i-leaf hypertrophy futhi ikhulise isivuno.
2. Khuthaza izithelo.Kungaba ukwandisa okukhipha utamatisi (utamatisi), isitshalo seqanda, apula nezinye izithelo nemifino.
3. Sheshisa ukuncipha kwezithelo.Ukunciphisa izithelo kungakhuphula isivuno, kuthuthukise izinga futhi kwenze usayizi wesithelo ufane.
4. Ukuqedwa kwamahlamvu ngokushesha.Kokotini nobhontshisi wesoya, ukucwiliswa kwamaqabunga kwenza ukuvuna kube lula.
5. Khulisa okuqukethwe ushukela ku-beet, umoba, njll.
Uma usebenzisa i-CPPU, naka amaphuzu alandelayo:
a.Uma isetshenziswa emagatsheni abuthakathaka ezitshalo ezindala, ezibuthakathaka, ezigulayo noma ezingenazithelo, ubukhulu besithelo ngeke buvuvuke kakhulu;ukuze kuqinisekiswe umsoco odingekayo ekuvuvukeni kwezithelo, kufanele kusetshenziswe izithelo nemifino efanelekile, futhi inani lezithelo akufanele libe liningi kakhulu.
b.I-CPPU kusilawuli sokukhula kwezitshalo isetshenziselwa ukusetha izithelo, ikakhulukazi ukuqhakaza kanye nokucubungula izithelo.Kufanele isetshenziswe ngokuqapha kumakhabe namakhabe, ikakhulukazi uma ukugxila kuphezulu, kulula ukukhiqiza imiphumela emibi efana nokuncibilika kwekhabe, ukunambitheka okubabayo, nokuqhekeka kamuva kwekhabe.
c.Umphumela wokuxuba i-chlorfenuron ne-gibberellin noma i-auxin ungcono kunokusetshenziswa okukodwa, kodwa kufanele wenziwe ngaphansi kokuqondisa kochwepheshe noma ngaphansi kwesisekelo sokuhlolwa kokuqala nokuboniswa.Ungasebenzisi ngokuzenzela.
d.Uma ukugxila okuphezulu kwesilawuli sokukhula kwesitshalo se-CPPU kusetshenziswe kumagilebhisi, okuqukethwe okuqinile okuncibilikayo kungancishiswa, i-acidity ingakhuphuka, futhi umbala nokuvuthwa kwamagilebhisi kuzobambezeleka.
e.Fafaza kabusha uma kunemvula phakathi namahora angu-12 ngemva kokwelashwa.
