Daim ntawv thov tseem ceeb ntawm 4-Chlorophenoxyacetic acid (4-CPA)
4-Chlorophenoxyacetic acid (4-CPA) yog phenolic cog kev loj hlob regulator. 4-Chlorophenoxyacetic acid (4-CPA) tuaj yeem nqus tau los ntawm cov hauv paus hniav, stems, nplooj, paj, thiab txiv hmab txiv ntoo ntawm cov nroj tsuag. Nws cov dej num lom neeg nyob ntev. Nws cov teebmeem physiological zoo ib yam li cov tshuaj hormones endogenous, stimulating cell division thiab cov ntaub so ntswg sib txawv, stimulating zes qe menyuam expansion, inducing parthenocarpy, tsim seedless txiv hmab txiv ntoo, thiab txhawb kev cog txiv hmab txiv ntoo thiab txiv hmab txiv ntoo expansion.
[Siv 1]Siv raws li cov nroj tsuag kev loj hlob regulator, txiv hmab txiv ntoo poob tiv thaiv, tshuaj tua kab mob, yuav siv tau rau lws suav paj thinning thiab txiv duaj txiv hmab txiv ntoo thinning
[Siv 2]Cog kev loj hlob hormone, siv raws li kev loj hlob regulator, txiv hmab txiv ntoo poob inhibiter, tshuaj tua kab mob, yuav siv tau rau txiv lws suav, zaub, txiv duaj ntoo, thiab lwm yam, thiab kuj siv raws li cov tshuaj intermediates. 4-Chlorophenoxyacetic acid (4-CPA) lub ntsiab daim ntawv thov 4-Chlorophenoxyacetic acid (4-CPA) yog tsuas yog siv los tiv thaiv paj thiab txiv hmab txiv ntoo poob, inhibit rooting ntawm taum, txhawb cov txiv hmab txiv ntoo, induce seedless txiv hmab txiv ntoo, thiab muaj ib tug ripening thiab loj hlob nyhuv. . 4-Chlorophenoxyacetic acid (4-CPA tuaj yeem nqus tau los ntawm cov hauv paus hniav, stems, paj thiab txiv hmab txiv ntoo, thiab nws cov kev ua haujlwm lom neeg nyob rau lub sijhawm ntev. Kev siv cov concentration yog 5-25ppm, thiab kab kawm lossis 0.1% potassium dihydrogen phosphate tuaj yeem ntxiv. Nws muaj qhov cuam tshuam zoo ntawm cov pwm grey, thiab kev siv dav dav yog 50-80ppm.
1. Thaum ntxov yield nce thiab loj hlob ntxov.
Nws ua haujlwm ntawm cov qoob loo nrog ntau lub ovules, xws li txiv lws suav, eggplants, figs, watermelons, zucchini, thiab lwm yam. Txau eggplants nrog 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA tov thaum lub sij hawm flowering, ob zaug ua ke, Nrog rau lub sijhawm ntawm 1 lub lis piam txhua zaus thaum txiv lws suav yog ib nrab ntawm kev tawg paj, tshuaj tsuag nrog 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA daws ib zaug. 4-Chlorophenoxyacetic acid (4-CPA daws ib zaug thaum lub sij hawm flowering.
2. 4-Chlorophenoxyacetic acid (4-CPA yog siv nyob rau hauv cov luam yeeb los txo cov ntsiab lus nicotine.
3. 4-Chlorophenoxyacetic acid (4-CPA yog siv nyob rau hauv ornamental paj ua kom paj loj hlob, nce paj tshiab thiab txiv hmab txiv ntoo, thiab ncua sij hawm flowering.
4. 4-Chlorophenoxyacetic acid Acid (4-CPA yog siv rau cov nplej, pob kws, nplej, taum thiab lwm yam qoob loo. Nws tuaj yeem tiv thaiv cov plhaub khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. kev loj hlob.
5. Ua kom cov qoob loo sib txawv ntawm cov zaub thiab txiv hmab txiv ntoo. Piv txwv li, cov txiv hmab txiv ntoo teeb tsa tus nqi ntawm txiv lws suav yog txhim kho. Thaum ntxov tawm los yog nce thiab lub sij hawm sau yog ntxov. Watermelon yog tshuaj tsuag, tawm los yog nce, xim yog zoo, cov txiv hmab txiv ntoo yog loj, qab zib thiab vitamin C ntsiab lus siab, thiab cov noob yog tsawg. Thaum lub sij hawm flowering lub sij hawm ntawm watermelon, 20 mg / / L ntawm anti-poob daws yog sprayed 1 mus rau 2 zaug, thiab 2 zaug yuav tsum tau muab cais. Rau Suav cabbage, 25-35 mg/L ntawm 4-Chlorophenoxyacetic acid (4-CPA tov yog sprayed nyob rau yav tav su rau ib hnub tshav ntuj 3-15 hnub ua ntej sau, uas yuav tiv thaiv tau lub cabbage los ntawm poob tawm thaum lub sij hawm cia thiab muaj cov nyhuv tshiab.
6. 4-Chlorophenoxyacetic acid (4-CPA yog siv los cog cov noob taum tsis muaj cag.
Kev ceev faj rau kev siv 4-CPA
(1) Tsis txhob siv 3 hnub ua ntej sau zaub.
Tus neeg sawv cev no muaj kev nyab xeeb dua li 2,4-D. Nws raug nquahu kom siv cov tshuaj tsuag me me los txau cov paj (xws li tshuaj tua kab mob caj pas) thiab tsis txhob txau rau ntawm cov ceg ntoo thiab cov paj tshiab. nruj me ntsis tswj qhov ntau npaum li cas, concentration thiab daim ntawv thov lub sij hawm los tiv thaiv cov tshuaj puas.
(2) Tsis txhob siv rau hnub kub thiab tshav ntuj lossis hnub los nag los tiv thaiv kev puas tsuaj rau tshuaj.
Tus neeg sawv cev no tsis tuaj yeem siv rau zaub rau cov noob.
