Hoobkas Muab Kev Loj Hlob ntawm Cov Nroj Tsuag Paclobutrazol CAS 76738-62-0 rau Kev Muag Khoom

Kev piav qhia txog khoom

Paclobutrazol (PBZ) yog ib qho tshuaj uas muajKev Tswj Xyuas Kev Loj Hlob ntawm Cov Nroj Tsuagthiab triazole Fungicide. Nws yog ib qho tshuaj tua kab mob uas paub zoo txogcov tshuaj hormones coggibberellin. Nws ua haujlwm los ntawm kev txwv tsis pub gibberellin biosynthesis, txo qhov kev loj hlob ntawm cov noob hauv cov noob kom muaj cov qia loj dua, ua rau cov hauv paus loj hlob ntxiv, ua rau cov txiv hmab txiv ntoo ntxov thiab ua rau cov noob ntau ntxiv rau cov nroj tsuag xws li txiv lws suav thiab kua txob.

Kev Siv

1. Kev cog cov noob nplej kom muaj zog: Lub sijhawm zoo tshaj plaws rau kev siv tshuaj rau cov nplej yog lub sijhawm uas muaj ib nplooj, ib lub plawv, uas yog 5-7 hnub tom qab tseb noob. Qhov ntau npaum li cas ntawm 15% paclobutrazol hmoov ntub dej yog 3 kilograms ib hectare nrog 1500 kilograms dej ntxiv (piv txwv li 200 grams ntawm paclobutrazol ib hectare nrog 100 kilograms dej ntxiv). Cov dej hauv daim teb cog noob qhuav, thiab cov noob raug txau kom sib npaug. Qhov concentration ntawm 15% paclobutrazol yog 500 npaug ntawm cov kua (300ppm). Tom qab kho, cov nroj tsuag elongation qeeb qeeb, ua tiav cov txiaj ntsig ntawm kev tswj kev loj hlob, txhawb kev tickling, tiv thaiv kev ua tsis tiav ntawm cov noob, thiab txhawb nqa cov noob.

2. Cog cov noob cog qoob loo uas muaj zog hauv peb nplooj theem ntawm cov noob cog qoob loo, siv 600-1200g ntawm 15% paclobutrazol hmoov ntub dej ib hectare, thiab ntxiv 900kg dej (100-200Chemicalbookppm) los tsuag cov qia thiab nplooj ntawm cov noob cog qoob loo, los txhawb kev tsim cov chlorophyll, txhim kho tus nqi photosynthetic, txo cov kab mob sclerotinia, txhim kho kev tiv thaiv, nce cov pods thiab cov qoob loo.

3. Yuav kom tiv thaiv cov taum pauv kom tsis txhob loj hlob sai dua li theem pib tawg paj, 600-1200 grams ntawm 15% paclobutrazol hmoov ntub dej ib hectare, 900 kg dej (100-200 ppm), thiab cov kua tshuaj tsuag rau ntawm qia thiab nplooj ntawm cov noob taum pauv kom tswj tau qhov ntev, nce cov pods thiab cov qoob loo.

4. Kev tswj kev loj hlob ntawm cov nplej thiab kev hnav khaub ncaws noob nrog qhov tob ntawm paclobutrazol kom zoo yuav ua rau cov noob cog muaj zog, ua rau cov noob tawg ntau dua, txo qhov siab, thiab ua rau cov qoob loo ntau dua. Sib tov 20 grams ntawm 15% paclobutrazol hmoov ntub dej nrog 50 kilograms ntawm cov noob nplej (piv txwv li 60ppm), nrog rau qhov siab txo qis ntawm cov nroj tsuag li 5% hauv Chemicalbook. Nws yog qhov tsim nyog rau kev tseb cov nplej thaum ntxov nrog qhov tob ntawm 2-3 centimeters, thiab yuav tsum siv thaum cov noob zoo, kev npaj av, thiab cov dej noo zoo. Tam sim no, kev tseb tshuab siv dav hauv kev tsim khoom, thiab nws yuav cuam tshuam rau qhov nrawm ntawm kev tshwm sim thaum qhov tob ntawm kev tseb nyuaj rau tswj, yog li nws tsis tsim nyog siv nws.
