Peb yuav tsum xyuam xim rau dab tsi thaum cog zaub hauv tsev cog khoom? Cov neeg ua liaj ua teb yuav tsum xyuam xim rau kaum lub ntsiab lus no!
Ua tib zoo saib xyuas zaub cultivation nyob rau hauv greenhouses
1. Ua tib zoo saib daim ntawv thov ntawm C02 roj chiv
Kev tsim nyog ntawm CO2 roj chiv tuaj yeem ua rau cov nroj tsuag loj hlob zoo thiab txhim kho cov khoom zoo thiab tawm los.
2, xyuam xim rau cov yam ntxwv ntawm zaub chiv
Greenhouse zaub yuav tsum tau dominated los ntawm bio-bacteria organic chiv thiab ntxiv los ntawm tshuaj chiv. Vim tias cov tsev cog khoom raug kaw, huab cua ncig yog txwv, thiab CO2 roj chiv tsis tuaj yeem ntxiv. Yog li ntawd, organic chiv yuav tsum tau ntxiv los daws qhov tsis muaj CO2 roj chiv. lus nug. Zaub teb, nplooj zaub yuav tsum xyuam xim rau nitrogen chiv, txiv hmab txiv ntoo zaub yuav tsum xyuam xim rau phosphorus thiab poov tshuaj chiv, paus zaub yuav tsum xyuam xim rau cov poov tshuaj chiv, thiab lub duav yuav tsum tau balanced fertilization.
3. Nco ntsoov tias phosphate chiv thiab zinc chiv tsis tuaj yeem siv ua ke
Kev kho tshuaj lom neeg feem ntau tshwm sim ntawm phosphorus thiab zinc, thiab kev siv ntau dhau ntawm phosphorus chiv yuav inhibit qhov nqus ntawm zinc. Qhov kub thiab av noo ntawm lub tsev xog paj yog qhov siab, thiab qhov ua tau zoo ntawm phosphorus yog 2 mus rau 3 npaug siab dua li qhov chaw qhib. Yog li ntawd, yuav tsum tau saib xyuas kom txo qis cov phosphorus kom tiv thaiv kev ua haujlwm ntawm zinc los ntawm inhibited. Hauv cov tsos mob ntawm zinc tsis txaus, 0 05 feem pua ~ 0.2 feem pua zinc sulfate foliar spray tuaj yeem siv.
4. Ua tib zoo saib xyuas kev sib cuam tshuam ntawm cov poov tshuaj thiab magnesium
Kev sib cuam tshuam ntawm cov poov tshuaj thiab magnesium feem ntau tshwm sim, yog li thaum siv cov poov tshuaj chiv rau zaub, nws yuav tsum tau fertilized los ntawm cov av thiab cov qoob loo. Piv txwv li, kev siv cov poov tshuaj ntau dhau tuaj yeem ua rau cov kab mob magnesium-deficiency physiological, yellowing thiab whitening ntawm cov leeg ntawm dib, thiab cov leeg tseem ntsuab, thiab daj thaj ua rau pom thawj zaug hauv nruab nrab nplooj ntawm txiv lws suav. Magnesium sulfate los yog calcium magnesium phosphate fertilizer leachate tuaj yeem txau thaum magnesium tsis txaus.
5. Ua tib zoo saib xyuas kev siv cov chiv nitrogen kom zoo
Cov chiv nitrogen ntau dhau yuav tsis tsuas yog ua rau muaj cov ntsiab lus nitrate siab hauv cov khoom noj zaub, uas tsis tuaj yeem ua raws li tus qauv tsis muaj kuab lom, tab sis kuj inhibit qhov nqus ntawm qee cov ntsiab lus. Kev siv ntau dhau ntawm nitrogen chiv yuav cuam tshuam rau kev nqus ntawm calcium, uas ua rau longitudinal splitting ntawm eggplant sepals thiab cork ntawm pulp; umbilical rot nyob rau hauv txiv lws suav thiab peppers; internal browning thiab rot ntawm cabbage. Cov chiv nitrogen ntau dhau tuaj yeem ua rau cov kab mob physiological xws li boron deficiency, potassium deficiency thiab magnesium deficiency hauv zaub.
6. Ceev faj tsis txhob siv cov tshuaj chlorine
Vim tias chloride ions tuaj yeem txo cov hmoov txhuv nplej siab thiab qab zib, ua kom tsis zoo, txo cov qoob loo, thiab tseem nyob hauv av, tshuaj lom hauv paus system, ua rau cov av compaction, nce av salinity, thiab ua kom av salinized.
7. Nco ntsoov tias nws tsis tsim nyog siv cov chiv nitrogen sai rau cov zaub hauv tsev cog khoom
Vim tias cov kua nitrogen ua kom nrawm nrawm yog yooj yim rau decompose thiab volatilize ammonia, tshwj xeeb tshaj yog nyob rau hauv lub tsev xog paj vim qhov kub thiab txias, cov nyhuv volatilization tseem phem dua. Txawm hais tias qhov qhib cua tso tawm thaum nruab hnub, nws yuav tsum tsis txhob siv dej los yog hauv lub qhov los tiv thaiv cov zaub los ntawm fumigated los ntawm ammonia kom puas nplooj thiab induce tuag vim ammonia.
8. Ua tib zoo saib xyuas qhov muaj phosphate chiv
9. Ua tib zoo saib xyuas kev siv potash chiv
Potassium chiv yog ib qho ntawm peb lub ntsiab ntawm chiv - -, kev siv cov poov tshuaj chiv tseem ceeb heev.
10. Cov zaub uas muaj lub sijhawm loj hlob luv tuaj yeem siv rau hauv qab ntawm ib zaug, thiab cov uas muaj lub sijhawm loj hlob ntev tuaj yeem siv rau hauv qab hauv ib nrab.
Nws yog qhov zoo tshaj plaws los thov cov poov tshuaj chiv ua ntej flowering, thiab foliar txau yuav tsum tau siv rau cov tsis muaj poov tshuaj nyob rau hauv lub sij hawm tom qab. Hlau tau yooj yim kho thiab hloov mus rau hauv cov tebchaw uas tsis sib haum los ntawm cov av thiab poob cov chiv ua kom zoo, thiab tsis tuaj yeem rov ua dua hauv cov nplooj zaub. Txau nrog {{0}}.1 feem pua ~ 0.3 feem pua ferrous sulfate aqueous tov, tshuaj tsuag tusyees thiab ua tib zoo, ib zaug txhua 5 ~ 7 hnub, tsuag 2 ~ 3 zaug tsis tu ncua. Yog hais tias hlau fertilizer yog siv rau cov av, nws yuav tsum tau tov nrog organic chiv tom qab composting.
