Paclobutrazol (PBZ) yog aPlant Loj hlob RegulatorthiabTshuaj tua kab mob.Nws yog ib tug paub antagonist ntawm cov nroj tsuag hormone gibberellin.Nws yog inhibiting gibberellin biosynthesis, txo qhov kev loj hlob ntawm internodial kom muab stouter stems, nce hauv paus kev loj hlob, ua rau cov txiv hmab txiv ntoo thaum ntxov thiab nce noob hauv cov nroj tsuag xws li txiv lws suav thiab kua txob. PBZ yog siv los ntawm arborists los txo cov kev loj hlob ntawm tua thiab tau pom tias muaj cov txiaj ntsig zoo ntxiv rau cov ntoo thiab cov nroj tsuag.Ntawm cov no tau txhim kho kev tiv thaiv rau kev ntxhov siab rau kev ntxhov siab, cov nplooj ntsuab tsaus, muaj zog tiv thaiv cov kab mob thiab cov kab mob, thiab txhim kho kev loj hlob ntawm cov hauv paus hniav.Cambial kev loj hlob, nrog rau kev loj hlob tua, tau pom tias txo qis hauv qee hom ntoo.Nws muaj Tsis muaj toxicity tawm tsam tsiaj.

Kev siv

1. Kev cog qoob loo muaj zog hauv cov nplej: Lub sijhawm tshuaj zoo tshaj plaws rau cov nplej yog ib nplooj, ib lub plawv lub sijhawm, uas yog 5-7 hnub tom qab sowing. Kev noj tshuaj kom tsim nyog yog 15% paclobutrazol wettable hmoov, nrog 3 kilograms ib hectare thiab 1500 kilograms dej ntxiv.

Kev tiv thaiv ntawm kev cog qoob loo: Thaum lub sij hawm cog qoob loo (30 hnub ua ntej mus), siv 1.8 kg ntawm 15% paclobutrazol wettable hmoov ib hectare thiab 900 kilograms dej.

2. Kev cog qoob loo muaj zog ntawm rapeseed thaum lub caij peb nplooj, siv 600-1200 grams ntawm 15% paclobutrazol wettable hmoov ib hectare thiab 900 kilograms ntawm dej.

3. Txhawm rau tiv thaiv cov taum pauv kom loj hlob ntau dhau thaum lub sijhawm pib paj, siv 600-1200 grams ntawm 15% paclobutrazol wettable hmoov ib hectare thiab ntxiv 900 kilograms dej.

4. Kev tswj kev loj hlob ntawm cov nplej thiab cov noob hnav khaub ncaws nrog qhov tsim nyog qhov tob ntawm paclobutrazol muaj cov yub muaj zog, nce tillering, txo qhov siab, thiab nce cov txiaj ntsig ntawm cov nplej.

Nco ntsoov

1. Paclobutrazol yog ib qho muaj zog loj hlob inhibitor nrog ib nrab-lub neej ntawm 0.5-1.0 xyoo nyob rau hauv cov av nyob rau hauv ib txwm tej yam kev mob, thiab ib tug ntev residual nyhuv. Tom qab txau nyob rau hauv daim teb los yog zaub yub theem, nws feem ntau cuam tshuam rau kev loj hlob ntawm cov qoob loo tom ntej.

2. nruj me ntsis tswj cov tshuaj noj. Txawm hais tias qhov siab dua qhov concentration ntawm cov tshuaj, qhov muaj zog ntawm kev tswj kav ntev, tab sis kev loj hlob kuj txo. Yog tias qhov kev loj hlob qeeb tom qab kev tswj hwm ntau dhau, thiab cov txiaj ntsig ntawm kev tswj kav ntev tsis tuaj yeem ua tiav ntawm qhov tsawg, qhov tsim nyog ntawm cov tshuaj tsuag yuav tsum tau siv sib npaug.

3. Kev tswj qhov ntev thiab tillering txo qis nrog qhov nce ntawm cov nyiaj sowing, thiab cov qoob loo ntawm cov qoob loo lig tsis pub tshaj 450 kilograms / hectare. Kev siv tillers los hloov cov noob yog raws li kev cog qoob loo. Tsis txhob muaj dej nyab thiab siv ntau dhau ntawm nitrogen chiv tom qab thov.

4. Kev loj hlob txhawb nqa cov nyhuv ntawm paclobutrazol, gibberellin, thiab indoleacetic acid muaj kev cuam tshuam antagonistic. Yog tias qhov ntau npaum li cas thiab cov yub raug cuam tshuam ntau dhau, nitrogen chiv lossis gibberellin tuaj yeem ntxiv los cawm lawv.

5. Cov nyhuv dwarfing ntawm paclobutrazol ntawm ntau hom nplej thiab nplej sib txawv. Thaum ua ntawv thov, nws yog ib qho tsim nyog yuav tsum tau hloov pauv los yog txo cov tshuaj kom tsim nyog, thiab tsis txhob siv cov tshuaj hauv av.
