Txau S-abscisic acid thaum lub sij hawm cov nplej booting thiab grain-filling theem zoo nce yield thiab txhim kho zoo. Nws cov txiaj ntsig tseem ceeb nyob hauv kev nce ntau txhiab nplej hnyav, txhim kho cov nplej zoo, thiab txhawb kev ntxhov siab; nws yog ib qho uas nquag siv cog kev loj hlob regulator nyob rau hauv "ib qho tshuaj tsuag, peb kev tiv thaiv" (kev siv tshuaj tua kab, kab mob, thiab kev tswj kev ntxhov siab) rau cov nplej.
Kev txheeb xyuas ntawm S-abscisic acid cov teebmeem tshwj xeeb
Ua ntau txhiab-grain hnyav kom nce yield
S-abscisic acid inhibits kev loj hlob ntau dhau (kab thiab nplooj elongation), yog li redirecting ntau cov as-ham rau grain filling. Ib txhij, nws txhim kho photosynthesis thiab accelerates synthesis thiab tsub zuj zuj ntawm amino acids thiab proteins. Qhov no txhawb nqa tag nrho cov qoob loo nthuav dav thiab kev loj hlob, nce ntau txhiab-grain hnyav. Cov ntaub ntawv qhia tias daim ntawv thov tsim nyog tuaj yeem nce txhiab-grain hnyav los ntawm 1-3 grams, thaum kawg ua rau cov qoob loo nce ntawm 5% -15%.
Txhim kho cov nplej zoo
S-abscisic acid txhawb nqa cov khoom qhuav - xws li cov hmoov txhuv nplej siab thiab cov protein - hauv cov nplej. Nws ua kom muaj kev thauj mus los ib txwm muaj txawm tias nyob rau hauv cov kev ntxhov siab xws li drought lossis kub kub, txo qhov feem ntawm shriveled los yog khoob nplej. Nws kuj txhim kho cov qoob loo plumpness thiab uniformity, yog li txhim kho kev ua haujlwm zoo; Cov kev txhim kho zoo no tshwj xeeb tshaj yog nyob rau thaj chaw ua liaj ua teb qhuav.
Txhim kho kev ntxhov siab thiab txo qhov kev pheej hmoo ntawm kev poob
Lub booting thiab grain-filling theem yog thaum nplej yog feem ntau yooj yim rau kev puas tsuaj los ntawm kub, qhuav cua thiab drought. S-abscisic acid ua rau cov nroj tsuag muaj kev ntxhov siab-teb cov kab ke, txhawb kev tiv thaiv kub, cua qhuav, kub kub, thiab dej qhuav. Nws txuas ntxiv lub neej ua haujlwm ntawm nplooj, tiv thaiv ntxov ntxov senescence thiab tshav kub-induced yuam ripening, thiab xyuas kom meej smooth grain filling-muab superior kev nyuaj siab-ua hauj lwm piv rau siv brassinosteroids ib leeg. Cov txheej txheem siv Standard
Rau lub caij ntuj no nplej, S-abscisic acid feem ntau yog siv rau hauv "ib qho tshuaj tsuag, peb tiv thaiv" (kev tswj hwm dav dav) tank mix. Cov ntsiab lus ntawm daim ntawv thov raug raws li hauv qab no:
Dosage: Rau 0.1% formulation, daim ntawv thov tus nqi yog 40-50 grams ib mu. Yog tias txau ib leeg, tus nqi pom zoo yog 20 milliliters ib mu rau 0.1% formulation, thaum lub 0.03% formulation yuav tsum tau diluted 1,500-fold ua ntej tshuaj tsuag.
Tank Mixing: Nws yog feem ntau tov nrog fungicides (xws li pyraclostrobin), tshuaj tua kab (xws li high-efficiency cypermethrin), thiab foliar chiv (xws li potassium dihydrogen phosphate). Txoj hauv kev no ib txhij tswj cov kab mob, kab tsuag, thiab kev puas tsuaj los ntawm qhuav, cua kub thaum boosting yield thiab zoo, ua rau nws lub ntsiab daim ntawv thov lub tswv yim thaum lub sij hawm booting thiab grain-filling theem.
