Brassinolide yog qhov thib rau loj tshaj plaws cog cov tshuaj hormones lees paub thoob ntiaj teb. Nws muaj lub luag haujlwm ntawm kev txhawb nqa kev loj hlob, txhawb cov hauv paus hniav hauv cov yub theem, txhim kho kev ntxhov siab, ua kom cov qoob loo thiab zoo, sib koom ua ke cov teebmeem thiab tshem tawm phytotoxicity. Nws yog siv dav hauv ntau ntau cov qoob loo loj xws li cov qoob loo roj, txiv hmab txiv ntoo, thiab zaub.
Tam sim no, muaj 5 lub ntsiab lus sau npe brassinolide cov khoom lag luam hauv khw: 24- sib xyaw epibrassinolide (kwv yees 60%-70% yog 22, 23, 24-epibrassinolide, txog 30%- 40 % yog24-epibrassinolide), 24-epibrassinolide, 28-epihomobrassinolide,28-homobrassinolide, thiab 14-hydroxybrassinosterol.
Brassinolides muaj ntau yam kev siv thiab tuaj yeem siv tau rau hauv yuav luag txhua cov qoob loo; Los ntawm cov noob soaking kom rov ua kom cov ntoo muaj zog tom qab sau, lawv tuaj yeem siv tau thoob plaws tag nrho cov txheej txheem kev loj hlob. Muaj ntau txoj hauv kev, xws li cov noob hnav khaub ncaws, sowing noob, drip irrigation, cag drenching, nplooj txau, aerial spraying, thiab lwm yam.; Nws muaj cov txiaj ntsig zoo, sib xyaw yooj yim, thiab siv dav siv ntau yam, yog li nws hu ua "panacea."
Txawm li cas los xij, hauv cov xwm txheej no, "panacea" brassinoids yuav tsum raug txwv:
1. Nws yog txwv tsis pub sib xyaw nrog cov tshuaj alkaline thiab tshuaj chiv
Tsis txhob sib tov brassinolides nrog alkaline chiv: Calcium-magnesium phosphate fertilizer, tsob ntoo tshauv, ammonium bicarbonate, sodium nitrate, potassium nitrate, nitro compound fertilizer, ammonia, thiab lwm yam. yuav tsum tsis txhob tov nrog alkaline tshuaj tua kab: Bordeaux sib tov, txiv qaub sulfur sib tov, thiab lwm yam. , txwv tsis pub phytotoxicity yuav tshwm sim.
2. Tsis txhob sib tov nrog tshuaj tua kab
Brassinoids tuaj yeem txo qhov kev puas tsuaj los ntawm cov tshuaj tua kab mob. Yog tias cov nroj tsuag nqus brassinoids, cov nroj tsuag yuav raug txo kom tsawg. Nws raug nquahu kom siv ob qho tib si tsawg kawg 7 hnub sib nrug.
3. Tsis txhob tsuag brassinoids rau ntawm thaj tsam ntawm kev loj hlob.
Brassinoids tuaj yeem txhawb kev faib cov hlwb hauv cov nroj tsuag thiab txhawb kev loj hlob. Yog tias muaj cov phiaj xwm loj hlob, qhov kev loj hlob yuav tsum tau tswj kom sai li sai tau es tsis txhob txau brassinoids.
4. Tsis txhob tsuag brassinoids rau hnub los nag lossis thaum muaj nag los hauv 6 teev
Thaum brassinoids tau txau rau hauv cov nplooj qoob loo, nws yuav siv sijhawm qee lub sijhawm rau lawv kom tau txais cov qoob loo. Yog tias nag los nag yuav ntxuav cov tshuaj. Nyob rau tib lub sijhawm, nws tseem yuav dilute ib qho concentration, uas yuav txo tau cov nyhuv ntawm brassinoids. Yog li ntawd, thaum txau brassinoids, xyuas cov huab cua huab cua ua ntej.
5. Brassinolides tsis tuaj yeem siv thaum lub sijhawm kub kub
Brassinoids yuav tsum tsis txhob muab txau rau ntawm nplooj thaum tav su, thaum kub siab tshaj plaws. Lub sijhawm no, nplooj evaporate sai sai. Ua ntej, nws tsis yooj yim rau cov qoob loo kom nqus tau. Nyob rau tib lub sijhawm, nws tiv thaiv cov evaporation sai ntawm cov dej ntawm qhov kub thiab txias thiab ua kom cov concentration ntawm cov tshuaj brassinoids.
6. Tsis txhob siv nyob rau hauv high concentrations
Brassinolide yog ib qho tshuaj lom neeg nrog cov qauv sterol bionic. Nws muaj qee qhov tsim nyog rau kev siv. Yog tias qhov concentration siab dhau lawm, nws yuav tsis tsuas yog ua rau khib nyiab xwb, tab sis kuj tseem tuaj yeem cuam tshuam cov qoob loo sib txawv.
7. Brassinolide tsis yog foliar chiv
Brassinolide yog cov nroj tsuag kev loj hlob regulator thiab belongs rau qeb ntawm tshuaj tua kab, tsis foliar chiv. Brassinolide nws tus kheej tsis muaj cov as-ham. Nws indirectly tswj cov qoob loo loj hlob los ntawm kev tswj cov endogenous hormone system ntawm cov nroj tsuag, thiab yog heev sib xws nrog foliar chiv. Txawm li cas los xij, brassinolide nws tus kheej tsis muaj cov as-ham, yog li nws yog ib qho tsim nyog los xyuas kom meej cov khoom noj khoom haus thiab kev sib xyaw "dej, chiv, thiab kev tswj hwm" kom brassinolide tuaj yeem ua lub luag haujlwm zoo dua hauv cov nroj tsuag.
Brassinoline classic compound formula
1. Brassinolide + pyraclostrobin
Raws li ib tug methoxyacrylic acid fungicide, pyraclostrobin muaj qhov zoo ntawm broad bactericidal spectrum, zoo heev nyhuv, kev ruaj ntseg rau cov qoob loo thiab kev loj hlob nce qib. Cov tshuaj sib xyaw ntawm brassinolide + pyraclostrobin tau txais kev pom zoo los ntawm ntau tus neeg cog qoob loo.
Nws qhov zoo yog: kev sib koom ua ke thiab muaj zog ua haujlwm sai; txhim khu kev tiv thaiv kab mob thiab txo cov tshuaj tiv thaiv; txhawb kev loj hlob thiab txo phytotoxicity.
2. Brassinolide + Tebuconazole
Tebuconazole yog cov tshuaj tua kab mob triazole uas muaj peb lub luag haujlwm tseem ceeb: kev tiv thaiv, kho, thiab tshem tawm. Nws muaj ib tug dav bactericidal spectrum thiab lub sij hawm ntev ntawm cov nyhuv. Txawm li cas los xij, tebuconazole nws tus kheej muaj qhov pom tseeb loj hlob-inhibiting nyhuv. Yog tias qhov concentration thiab lub sij hawm tsis raug tswj kom zoo thaum siv, nws tuaj yeem ua rau cov nroj tsuag qeeb qeeb.
Cov mis ntawm brassinolide + tebuconazole tuaj yeem txo qhov kev loj hlob inhibition los ntawm kev siv tebuconazole, thiab tib lub sijhawm ua kom lub cev nqus thiab ua haujlwm ntawm tebuconazole los ntawm cov qoob loo, ua tiav cov txiaj ntsig zoo thiab txo phytotoxicity.
3. Brassinolide + potassium dihydrogen phosphate
Potassium dihydrogen phosphate yog high-phosphorus thiab high-potassium foliar fertilizer uas tuaj yeem muab cov phosphorus thiab potassium zoo rau cov qoob loo. Siv ua ke nrog brassinolide, nws tuaj yeem txhim kho qib metabolic ntawm cov qoob loo thiab txhawb kev nqus, kev ua haujlwm thiab kev hloov pauv ntawm cov poov tshuaj dihydrogen phosphate.
Kev siv brassinolide + potassium dihydrogen phosphate ntawm lub sijhawm sib txawv tuaj yeem ua haujlwm ntau yam xws li txhawb cov nplooj photosynthesis, tiv thaiv khaub thuas thiab Frost, tiv thaiv drought, tiv taus qhuav thiab kub cua, tiv thaiv chaw nyob, ua kom cov txiv hmab txiv ntoo muaj nqis, txhim kho cov txiv hmab txiv ntoo zoo thiab nce yield. .
4. Brassinolide +920
920 yog lub npe nrov rau cov nroj tsuag regulator gibberellic acid. Nws muaj lub luag haujlwm ntawm kev txhawb nqa kev loj hlob ntawm cov noob, ua kom cov txiv hmab txiv ntoo loj, thiab elongating pob ntseg ntawm cov qoob loo. Txawm li cas los xij, kev siv tsis raug tuaj yeem ua rau muaj qhov tsis zoo xws li kev cog qoob loo ntau dhau, kev loj hlob ntau dhau, thiab cov txiv hmab txiv ntoo deformed.
Kev siv ua ke ntawm brassinolide + 920 tuaj yeem txo qhov kev pheej hmoo ntawm phytotoxicity tshwm sim los ntawm kev siv 920 ib leeg. Brassinolide tuaj yeem sib npaug ntawm cov tshuaj hormones endogenous ntawm cov qoob loo, txhim kho photosynthesis ntawm cov qoob loo, txhawb kev loj hlob ntawm cov qoob loo, thiab cov txiv hmab txiv ntoo ib txwm loj hlob.
Brassinolides muaj kev nyab xeeb thiab siv tau zoo, thiab tuaj yeem siv rau ntau yam qoob loo hauv ntau theem. Tom qab xyoo ntawm kev nce qib thiab daim ntawv thov, ntau cov kev daws teeb meem zoo heev tau tsim.
