Agriculture Chemical Cog Loj hlob Hormone Paclobutrazol

Paclobutrazol(PBZ) yog aPlant Loj hlob Regulatorthiab triazoleTshuaj tua kab mob. Nws yog ib tug paub antagonist ntawm cov nroj tsuag hormone gibberellin. Nws ua los ntawm 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.

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. Qhov tsim nyog npaum li cas ntawm 15% paclobutrazol wettable hmoov yog 3 kilograms ib hectare nrog 1500 kilograms ntawm dej ntxiv (xws li 200 grams ntawm paclobutrazol ib hectare nrog 100 kilograms ntawm dej ntxiv). Cov dej nyob rau hauv lub yub yub yog qhuav, thiab lub seedlings yog evenly sprayed. Cov concentration ntawm 15%paclobutrazolyog 500 npaug ntawm cov kua (300ppm). Tom qab kev kho mob, cov nroj tsuag elongation tus nqi qeeb qeeb, ua tiav cov txiaj ntsig ntawm kev tswj kev loj hlob, txhawb nqa tillering, tiv thaiv yub tsis ua haujlwm, thiab ntxiv dag zog rau cov noob.

2. Kev cog qoob loo muaj zog nyob rau hauv peb nplooj theem ntawm rape seedlings, siv 600-1200g ntawm 15% paclobutrazol wettable hmoov ib hectare, thiab ntxiv 900kg dej (100-200Chemicalbookppm) tshuaj tsuag stems thiab nplooj ntawm rape seedlings, los txhawb chlorophyll. synthesis, txhim kho photosynthetic tus nqi, txo tus kab mob sclerotinia, txhim khu kev tiv thaiv, nce pods thiab tawm los.

3. Txhawm rau tiv thaiv cov taum pauv kom loj hlob sai dua li qhov pib tawg paj, 600-1200 grams ntawm 15% paclobutrazol wettable hmoov ib hectare, 900 kg dej (100-200 ppm), thiab cov kua tshuaj tsuag lub qia thiab nplooj ntawm soybean seedlings. tswj qhov ntev, nce pods thiab tawm los.

4. Nplej kev loj hlob tswj thiab noob hnav khaub ncaws nrog haum qhov tob ntawmPaclobutrazolmuaj ib tug muaj zog yub, nce tillering, txo qhov siab, thiab nce yield nyhuv ntawm cov nplej. Sib tov 20 grams ntawm 15% paclobutrazol wettable hmoov nrog 50 kilograms ntawm cov noob nplej (piv txwv li 60ppm), nrog rau cov nroj tsuag qhov siab txo qis ntawm li 5% hauv Chemicalbook. Nws yog qhov tsim nyog rau kev cog qoob loo thaum ntxov nrog qhov tob ntawm 2-3 centimeters, thiab yuav tsum tau siv thaum cov noob zoo, kev npaj av, thiab cov ntsiab lus noo noo zoo. Tam sim no, tshuab sowing yog dav siv nyob rau hauv ntau lawm, thiab tej zaum yuav cuam tshuam qhov tshwm sim tus nqi thaum lub sowing qhov tob yog nyuaj rau tswj, yog li nws yog tsis tsim nyog siv nws.
