Yam cuam tshuam rau cov nyhuv ntawm foliar fertilizer
Nplooj
Nplooj siv quav ciab thiab cuticle thickness, nplooj nplooj, thiab lwm yam tuaj yeem cuam tshuam rau kev nqus ntawm foliar chiv. Cov nplooj tshiab nrog nyias cuticles thiab cov nplooj muaj zog muaj zog muaj txiaj ntsig zoo ntawm foliar chiv. Urea muaj cov nyhuv softening ntawm cuticle ntawm epidermal hlwb thiab tuaj yeem ua kom nkag mus rau lwm cov as-ham, yog li urea tau dhau los ua ib qho tseem ceeb ntawm foliar chiv. Cov xab npum nruab nrab, silicone additives, thiab lwm yam tuaj yeem soften lub cuticle, txhim kho kev sib kis ntawm cov tshuaj chiv, ua rau thaj chaw sib cuag nrog nplooj, thiab txhim kho kev nqus. Nplooj muaj hnub nyoog feem ntau muaj feem xyuam rau nplooj nplooj, thiab nplooj tshiab yog yooj yim rau nqus cov as-ham dua li cov nplooj qub.
Kev noj zaub mov zoo ntawm cov nroj tsuag nws tus kheej
Cov nroj tsuag tsis muaj zaub mov muaj peev xwm nqus tau cov as-ham. Yog tias cov nroj tsuag loj hlob ib txwm thiab cov khoom noj txaus txaus, nws yuav nqus tsawg dua tom qab txau foliar chiv; txwv tsis pub, nws yuav nqus tau ntau dua.
Ib puag ncig tej yam kev mob
Lub teeb, av noo, kub, thiab lwm yam muaj kev cuam tshuam zoo rau kev nqus ntawm foliar chiv. Lub teeb tsis muaj zog thiab huab cua siab yog qhov tsim nyog rau kev nqus ntawm foliar chiv. Yog hais tias qhov concentration ntawm foliar fertilizer siab dhau lawm thiab cov dej evaporates sai heev, nws yuav hlawv nplooj thiab ua rau chiv puas. Feem ntau, nyob rau hnub huab cua los yog thaum 4:00 ~ 5:00 yav tav su, thaum kub yog 20 ~ 25 degrees Celsius, cov nyhuv ntawm foliar fertilizer spraying yog zoo dua.
Cov cuab yeej ntawm cov tshuaj txau
Cov concentration ntawm cov tshuaj, pH tus nqi, nto nro ntawm kev daws, kev txav ntawm cov khoom noj khoom haus, thiab lwm yam kuj cuam tshuam rau kev nqus ntawm foliar chiv. Cov nplooj foliar sib txawv muaj qhov sib txawv tsim nyog, thiab cov concentration ntawm cov tshuaj txau yuav tsum tau kho raws li qhov yuav tsum tau ua. Thaum muab cations, cov tshuaj yog kho me ntsis alkaline; Thaum muab cov anions, cov tshuaj yog hloov mus rau me ntsis acidic, uas yog conducive rau lub nqus ntawm nutrient ntsiab. Cov kws tshaj lij ntseeg tias ntxiv 2% cov tshuaj ntxhua khaub ncaws nruab nrab rau cov tshuaj txau tuaj yeem txo qhov nro ntawm cov tshuaj, ua kom thaj chaw sib cuag ntawm cov tshuaj thiab nplooj, thiab nqus cov as-ham sai dua. Kev nqus ntawm nplooj yog qhov zoo sib xws nrog kev txav ntawm cov as-ham hauv nplooj. Cov khoom noj uas muaj cov khoom noj ceev ceev hauv cov nplooj kuj absorbed sai dua.
Kev txav ceev ntawm ntau yam hauv cov nplooj nplooj
Kev txav ceev ntawm cov ntsiab lus hauv cov nplooj yog feem ntau: nitrogen> potassium> phosphorus> sulfur> zinc> hlau> tooj liab> manganese> molybdenum> boron> calcium. Thaum txau cov ntsiab lus uas tsis yooj yim rau kev txav mus los, nws yog ib qho tsim nyog yuav tsum tau ua kom cov tshuaj tsuag ntau ntxiv thiab ua tib zoo saib xyuas qhov chaw txau. Piv txwv li, hlau, boron, molybdenum, thiab lwm yam, uas txav mus qeeb, yog zoo dua txau rau ntawm nplooj tshiab. Tsis tas li ntawd, lub sijhawm cov tshuaj ntub cov nplooj kuj cuam tshuam rau kev nqus ntawm foliar chiv. Feem ntau, qhov nqus tau nrawm tshaj plaws thaum nplooj ntub rau 30 feeb mus rau 1 teev.
