Lub luag haujlwm ntawmbrassinolide tshuaj
1. Txhawb cov hauv paus hniav ntawm yub theem
Siv los kho cov noob los yog tshuaj tsuag rau ntawm theem seedbed, nws muaj qhov pom tseeb kev loj hlob-txhawb cov hauv paus hniav ntawm nplej, nplej, pob kws, taum dav, luam yeeb, zaub thiab lwm yam qoob loo.
Piv nrog rau kev tswj hwm, qhov hnyav ntawm cov hauv paus system tau nce los ntawm 20 feem pua -50 feem pua, thiab qhov hnyav qhuav nce 15 feem pua -107 feem pua.
2. Txhawb lub sijhawm khoom noj khoom haus
Brassinolide muaj ob qho kev cuam tshuam ntawm kev txhawb nqa cell division thiab cell elongation, thiab tseem tuaj yeem ua kom cov ntsiab lus ntawm chlorophyll hauv nplooj, txhim kho photosynthesis, thiab nce cov khoom khaws cia ntawm cov khoom siv photosynthetic, yog li nws muaj txiaj ntsig zoo rau kev txhawb nqa cov nroj tsuag kev loj hlob thiab tuaj yeem txhim kho qoob loo. tawm los.
3. Kev txhawb nqa lub sij hawm ua me nyuam
Brassinolide tuaj yeem txhim kho qhov germination tus nqi paj ntoos, txhawb lub elongation ntawm paj ntoos hlab, thiab muaj txiaj ntsig zoo rau fertilization ntawm cov nroj tsuag, yog li txhim kho tus nqi ntawm cov noob thiab cov txiv hmab txiv ntoo. Nyob rau hauv lub mature theem ntawm cov qoob loo, tus naj npawb ntawm cov nplej thiab grain hnyav nce, thiab cov txiv hmab txiv ntoo ntawm melons thiab txiv hmab txiv ntoo yog uniform, uas txhim kho cov qoob loo zoo.
4. Txhim khu kev tiv thaiv kev ntxhov siab
Tom qab cov brassinolide nkag mus rau hauv cov nroj tsuag, nws tsis tsuas yog ntxiv dag zog rau cov photosynthesis, txhawb kev loj hlob thiab kev loj hlob, tab sis kuj txhawb ib co kev tiv thaiv enzyme kev ua si nyob rau hauv cov nroj tsuag, uas yuav ua tau zoo heev txo cov teeb meem tshuaj (xws li Malondialdehyde, thiab lwm yam) kev puas tsuaj rau lub cev muaj nuj nqi. .
Ntau cov kev tshawb fawb thiab kev sim teb tau ua pov thawj tias brassinolide tuaj yeem txhim kho qhov kev ntxhov siab ntawm cov qoob loo, tshwj xeeb tshaj yog nyob rau hauv cov yam ntxwv ntawm drought resistance thiab kub tsis kam, cov nyhuv yog pom tseeb dua.
5. Txo cov tshuaj puas tsuaj
Thaum siv tshuaj tua kab mob, fungicides thiab tshuaj tua kab tsis raug, lossis qhov sib piv tsis tsim nyog, phytotoxicity yog qhov tshwm sim. Kev siv sijhawm ntawm brassinolide ntxiv rau cov tshuaj foliar zoo tuaj yeem kho cov khoom noj khoom haus, ntxiv kev noj haus, txo kev puas tsuaj, thiab ua kom cov qoob loo rov zoo.
Lus Cim: Thaum soj ntsuam nrog phytotoxicity, xyuam xim rau kev siv cov concentration ntawm brassinolide. Cov concentration ntau dhau tuaj yeem ua rau phytotoxicity hnyav dua.
