Tam sim no, nws yog tsuas yog siv rau cov noob nplej, uas muaj cov peev txheej germination, txhawb kev loj hlob germination, txhawb nqa lub zog ua ke thiab txhim kho tsob ntoo tsis kam. Siv 0.3-0.4 mg / l thiab soaking noob rau 24-48 teev tuaj yeem txhawb kev germination.

4. Sodium nitrophenolates (atonik)

Sodium nitrophenolates (atonik) tuaj yeem nkag mus rau hauv cov nroj tsuag lub cev tom qab sib cuag nrog cov nroj tsuag ntawm tes protoplasm, thiab txhim kho cov kev loj hlob cell. Soaking cov noob tuaj yeem txhawb cov noob germination thiab rooting, tawg dormancy, thiab tuaj yeem ua kom muaj zog muaj sia nyob tom qab cov tshuaj tsuag rau cov noob. Nws tuaj yeem txhawb cov metabolism thaum txau rau ntawm nplooj. Txau thaum lub caij ua paj tau tuaj yeem tiv thaiv cov paj poob, nce tawm los, txhim kho kom zoo thiab sau ntxov.

5. 1-naphyyl acetic acid (NAA)

1-naphyyl acetic acid (NAA) yog ib tsob nroj loj loj kev tswj hwm uas txhawb nqa cov hauv paus hniav loj hlob. Nws muaj cov haujlwm ntawm kev txhawb nqa xov tooj ntawm tes thiab nthuav tawm, ua rau cov txiv ntoo tso tseg, thiab hloov cov qauv ntawm cov poj niam thiab txiv neej paj. NaphthaleAcetic acid tau ntev tau siv dav hauv kev ua liaj ua teb, nce cov txiv ntoo, thiab tiv thaiv cov txiv ntoo poob ua ntej sau.



6. Choline chloride

Choline chloride yog qhov dav dav cog cov kev tswj hwm kev txhim kho uas tuaj yeem txhawb nqa cov noob qoob loo, thiab yog li ua kom muaj zog tawm thiab txhim kho kom zoo.

7. Uniconazole

Uniconazole yog qhov dav-spectrum, high-eff-efficiency cog cov kev cai lij choj muaj cov bactericidal thiab herbicidal cuam tshuam. Nws yog gibberelelin synthesis inshibitor. Uniconazole muaj qhov cuam tshuam ntawm kev tswj cov zaub kom loj hlob yooj yim, tiv thaiv kab hauv tsev, kev txhawb nqa tom qab Nws yog qhov haum rau mov, nce tillering, tswj cov chaw kom qhov siab, thiab txhim kho chaw lodging tsis kam. Siv 50 ~ 200 tsaus ntuj / kg rau cov noob nplej nplej. Siv 50mg / kg rau cov mov thaum ntxov, thiab 50 ~ 200mg / kg rau ib leeg-lub caij nplej lossis cov nplej tom qab nyob ntawm ntau yam. Qhov piv ntawm cov noob ntim rau cov kua ntim yog 1: 1.2: 1.5. So li cov noob rau 36 (24-28) teev, thiab sib tov cov noob ib zaug txhua 12 teev los pab txhawb cov noob duab noob. Tom qab ntawd siv ib qho me me ntxuav thiab germinate thiab tseb. Nws tuaj yeem ua kom luv luv thiab muaj zog seedlings nrog ntau tus toillers.

8. Triacontanol

Triacontanol yog ib tsob nroj loj hlob promoter nrog ntau cov ntawv thov. Nws yog feem ntau muab rho tawm los ntawm beeswax, bran wax thiab pas nrig siv ciab. Triacontanol Foliar Txau muaj cov nyhuv tam sim rau kev txhawb nqa Chlorophyl cov ntsiab lus. Tom qab 4 feeb ntawm kev kho mob, kev nce ntxiv zom cov piam thaj thiab cov ntsiab lus amino acid tuaj yeem pom hauv cov poov yub. Nws muaj cov txiaj ntsig zoo-ua kom muaj txiaj ntsig ntawm mov, nrog kev nce ntau dua 10%.

9. Etephon

Etephon ua si lub luag haujlwm tseem ceeb hauv kev loj hlob thiab koom nrog cov txheej txheem dormancy, txhawb kev tawg paj, thiab txhawb cov txiv hmab txiv ntoo ripening.

10. Pacloburanzol (Paclo)

Pacloburanzol (Paclo) tau siv dav hauv kev sib tawb hauv cov nplej. It can inhibit the synthesis of endogenous gibberellins in plants, reduce cell division and elongation, make cells in various parts of rice smaller, delay plant growth and aging, and increase the activity of indoleacetic acid oxidase in rice, thereby weakening the apical growth advantage of rice seedlings, increasing tillering, increasing the number of green leaves of seedlings, promoting root growth, and enhancing the resistance of seedlings to stress. Pacloburanzol tuaj yeem nqus tau los ntawm cov noob nplej, nplooj, thiab cov hauv paus hniav, yog li nws tuaj yeem siv rau cov noob nplej hnav khaub ncaws kom nce tus nqi germination; Txau thaum lub sijhawm ua cov nplej yog ua rau kev cog lus luv thiab muaj zog seedlings; Txau thaum lub sijhawm ua panicicity txawv lub sij hawm txhawb kev dwarfing thiab chaw nyob ntawm cov nroj tsuag; Nws tseem tuaj yeem ua rau muaj kev loj hlob ntawm cov nroj hauv cov yub yub thiab nce cov qoob loo tawm.
