Cov tswv yim tswj xyuas thiab pom zoo cog kev loj hlob Regulators rau Qos Seedling theem

Lub hom phiaj tseem ceeb ntawm kev tswj xyuas thaum lub sij hawm cov qos yaj ywm yub theem yog "txhim kho cov hauv paus kev loj hlob thiab ntxiv dag zog rau cov nroj tsuag, tswj kev loj hlob ntau dhau thaum tiv thaiv kab mob, thiab kev tshawb fawb sib npaug saum av thiab hauv av loj hlob." Kev tswj xyuas thaum lub sijhawm no ncaj qha txiav txim siab tus lej tom ntej ntawm tubers thiab lawv lub peev xwm loj. Ua raws li koj qhov kev siv zog txuas ntxiv los txhim kho cov txheej txheem cog qoob loo, cov hauv qab no yog lub hom phiaj, kev tswj xyuas kom zoo.

I. Kev Tswj Xyuas Cov Ntsiab Cai rau Cov Seem Theem (Los ntawm Kev Kub Ntxhov mus rau theem Rosette; kwv yees li 15–20 hnub)
Txhaum Mulch zaj duab xis tso cov noob + Earthing kom txuag tau cua sov
Rau kev cog qoob loo ntawm cov yas-mulched, zaj duab xis yuav tsum tau tawg raws sijhawm kom tso cov yub tawm tshiab, yog li tiv thaiv cov cua sov los ntawm qhov kub thiab txias hauv qab zaj duab xis. Subsequently, fine soil should be used to tightly seal the holes in the film to raise soil temperature, conserve moisture, and suppress weeds.

Inter-tillage and Av Loosening + Earthing Up los txhawb cov hauv paus kev loj hlob

Los ntawm lub sij hawm ntawm qhov tshwm sim mus txog rau thaum lub seedlings loj hlob 7-8 nplooj tiag tiag, ua heev inter-tillage kom loosen cov av, nce av kub, thiab txhawb kev loj hlob ntawm cov hauv paus hniav.
Ua ke nrog inter-tillage, ua thawj puag ncig ntawm earthing up (hilling). Tsim kom muaj qhov siab ntawm ridges los pab txhawb kev loj hlob ntawm stolons thiab txhawb kev tsim tuber.
Kev Tswj Dej: Cia nws qhuav me ntsis dua li ntub; Tiv thaiv Waterlogging
Seedlings yuav tsum tau me ntsis dej thaum lub sij hawm no theem; tswj cov av noo ntawm 60% -70% ntawm thaj chaw muaj peev xwm txaus. Nyob rau hauv cov cheeb tsam uas nquag los nag hnyav heev, siv qhov zoo ntawm lub hnub ci lub sijhawm kom tshem tawm cov kwj dej thiab tiv thaiv kev puas tsuaj rau cov qos yaj ywm.

Kev hnav khaub ncaws saum toj kawg nkaus los txhawb kev loj hlob ntawm cov noob: Fertilize Raws li Seedling Vigor; Synergize Nitrogen thiab Potassium

Thaum cov yub tau tshwm sim tsis sib xws, siv 5-6 kg ntawm urea ntxiv rau 5-8 kg ntawm poov tshuaj sulfate ib evkawj los txhawb kev loj hlob ntawm yub.
Yog hais tias daim ntawv thov basal chiv txaus thiab cov yub tshwm sim, cov hnav khaub ncaws saum toj kawg nkaus yuav raug tshem tawm. Rau cov yub tsis muaj zog, siv cov tshuaj tua kab mob ntawm monopotassium phosphate (200 g ib * mu * diluted hauv 60 kg dej) 1-2 zaug.
Kev Tiv Thaiv Thaum Ntxov thiab Tswj Kab Tsuag thiab Kab Mob

Late Blight: Yog tias kub tshaj 18 ° C ​​thiab nrog rau cov huab cua los nag lossis nag, tshuaj tsuag Mancozeb ua kev tiv thaiv. Yog tias pom cov nroj tsuag kab mob focal, tshem tawm tam sim ntawd thiab ua raws li kev tswj hwm thiab kev kho mob. II. Pom zoo cog kev loj hlob Regulators thiab cov lus qhia rau kev thov
Cog Loj hlob Regulator: Monopotassium Phosphate (Functional Regulator)
Lub luag haujlwm tseem ceeb: Replenishes phosphorus thiab potassium as-ham, txhim kho photosynthesis, txhawb kev loj hlob hauv paus, thiab txhim kho kev ntxhov siab.

Pom zoo Lub Sijhawm Thov: Thaum lub sij hawm yub theem, tshwj xeeb tshaj yog rau cov tsis muaj zog seedlings los yog thaum lub hauv paus kev loj hlob tsis zoo.
Daim ntawv thov thiab kev ceev faj: Siv cov tshuaj tsuag foliar siv 0.3% tov (sib tov 200 grams ib evkawj nrog 60 liv dej). Thov ib zaug txhua 7-10 hnub, rau tag nrho 1-2 daim ntawv thov sib law liag.
Siv ceev faj ntawm cov yub loj heev kom tsis txhob muaj kev loj hlob ntau dhau (etiolation).

Plant Loj hlob Regulator: Paclobutrazol (Paclo)
Lub luag haujlwm tseem ceeb: Paclobutrazol inhibits kev loj hlob ntau dhau (kab thiab nplooj elongation), txhawb kev hloov pauv ntawm cov as-ham mus rau hauv av, thiab pab tswj kev loj hlob zoo thaum txhawb kev tsim tuber.
Pom zoo Daim Ntawv Thov Sijhawm: Los ntawm lub sijhawm ntxov budding mus rau theem pib flowering (xws li "lub sijhawm kub" rau kev tswj kev loj hlob zoo).

Daim ntawv thov thiab kev ceev faj: Sib tov 40-60 grams ntawm 15% Paclobutrazol Wettable Powder ib daim av nrog dej thiab siv tshuaj tsuag; tsom rau daim ntawv thov tshwj xeeb ntawm cov ntsiab lus loj hlob apical.
Nco tseg: Tsis txhob siv ntxov dhau, vim qhov no tuaj yeem cuam tshuam cov nroj tsuag ib txwm muaj.


Cog Loj hlob Regulator: Mepiquat Chloride
Lub luag haujlwm tseem ceeb: Mepiquat Chloride tswj hwm cov tshuaj hormones endogenous, suppresses apical dominance, thiab pab tiv thaiv qhov chaw nyob (kab vau).

Daim Ntawv Thov Lub Sijhawm Pom Zoo: Thaum muaj kev nyiam mus rau kev loj hlob ntau dhau los tau pom ua ntej mus rau theem budding.
Daim ntawv thov thiab kev ceev faj: Sib tov 20 mL ntawm 250 g / L Mepiquat Chloride Aqueous Solution nrog 20 kg ntawm dej ib evkawj, thiab siv sib npaug li cov tshuaj tsuag.

Cog Loj hlob Regulator: Brassinolide
Lub luag haujlwm tseem ceeb: Brassinolide txhim kho kev ntxhov siab, txo cov teebmeem ntawm qhov kub thiab txias, thiab txhawb kev faib cov cell.
Daim Ntawv Thov Sijhawm Pom Zoo: Ua ntej lossis tom qab cua txias, lossis lub sijhawm rov qab los rau cov noob tsis muaj zog.

Daim ntawv thov txoj kev thiab ceev faj: Siv 10 mL ntawm 0.01% Brassinolide Aqueous Solution rau ib daim av raws li cov tshuaj tsuag foliar; Nws tuaj yeem sib xyaw nrog Monopotassium Phosphate los txhim kho kev ua tau zoo.
