Paclobutrazol kawirikawiri ndi ufa, womwe ukhoza kulowetsedwa mumtengo kudzera mumizu, zimayambira ndi masamba a mitengo ya zipatso pansi pa madzi, ndipo uyenera kugwiritsidwa ntchito pa nthawi ya kukula. Nthawi zambiri pamakhala njira ziwiri: kufalitsa dothi ndi kupopera mbewu mankhwalawa.
1. Kukwiriridwa paclobutrazol
Nthawi yabwino kwambiri ndi pamene mphukira yachiwiri imaphukira pafupifupi 3-5 cm (pamene chikasu chimasanduka chobiriwira kapena chisanakhale chobiriwira). Malinga ndi kukula kwa korona, mitundu yosiyanasiyana, ndi dothi losiyanasiyana, paclobutrazol amagwiritsidwa ntchito.
Nthawi zambiri, katundu kuchuluka kwa paclobutrazol umagwiritsidwa ntchito pa lalikulu mita korona wa 6-9 g, dzenje kapena mphete ngalande anatsegula 30-40 masentimita mkati kukapanda kuleka mzere kapena 60-70 cm kuchokera pamtengo mutu, ndi yokutidwa ndi dothi. pambuyo kuthirira. Ngati nyengo youma, Phimbani nthaka mutatha kuthirira bwino.
Kugwiritsa ntchito paclobutrazol sikuyenera kukhala koyambirira kapena mochedwa. Nthawi yeniyeni imakhudzana ndi zosiyanasiyana. Kumayambiriro kwambiri kungayambitse mphukira zazifupi ndi kupunduka; mochedwa, mphukira yachiwiri idzatumizidwa mphukira yachitatu isanatembenuke kobiriwira. .
Dothi losiyanasiyana lidzakhudzanso kugwiritsa ntchito paclobutrazol. Nthawi zambiri, nthaka yamchenga imakhala ndi zotsatira zabwino zokwirira kuposa dongo. Ndibwino kuti mugwiritse ntchito paclobutrazol m'minda ya zipatso yokhala ndi kukhuthala kwa nthaka.
2. Foliar kupopera mbewu mankhwalawa paclobutrazol kulamulira mphukira
Kupopera kwa paclobutrazol foliar kumakhala ndi zotsatira zofewa kusiyana ndi mankhwala ena, ndipo kumatha kuchepetsa kuwonongeka kwa mtengo panthawi yowombera. Kawirikawiri, pamene masamba atembenuka obiriwira ndipo osakhwima mokwanira, gwiritsani ntchito paclobutrazol 15% ufa wonyezimira kwa nthawi yoyamba pafupifupi 600 nthawi, ndipo pang'onopang'ono muwonjezere kuchuluka kwa paclobutrazol 15% ufa wonyezimira kachiwiri. Control kuwombera kamodzi - masiku 10. Pambuyo powongolera mphukira 1-2 nthawi, mphukira zimayamba kukhwima. Zindikirani kuti mphukira sizinakhwime mokwanira, sizimawonjezera ethephon, apo ayi ndizosavuta kuyambitsa masamba.
Masamba akasanduka obiriwira, olima zipatso ena amagwiritsa ntchito paclobutrazol poyang'anira mphukira. Mlingo ndi 1400 magalamu ndi 450 kg ya madzi. Kuwongolera kwachiwiri kwa mphukira kumakhala kofanana ndi koyamba. Mlingo udzachepetsedwa pambuyo pake mpaka kufika 400. Ndi 250 ml ya ethephon. Poyamba kuyang'anira mphukira, zomwe zimachitika nthawi zonse ndikuwongolera kamodzi masiku asanu ndi awiri aliwonse, koma mawu a dzuwa kapena zinthu zina ziyenera kuganiziridwa. Pambuyo pokhazikika, imatha kuyendetsedwa kamodzi masiku khumi aliwonse.
