Sib tov sib piv ntawm sodium nitrophenolates thiab urea li paus chiv thiab aindressing chiv
① Pib Pib Sib Txuas Sib Txuas
Sodium nitrophenolates thiab urea tau sib xyaw ua ke ua paus chiv, uas yog, ua ntej sowing lossis cog. Qhov sib xyaw sib xyaw yog: 1.8% sodium nitrophenolate (20-30 grams), 45 phaus ntawm urea. Rau cov sib tov no, ib qho acre feem ntau txaus. Ib qho ntxiv, tus nqi ntawm urea tuaj yeem hloov kho kom zoo, feem ntau yog raws li cov av.
② Topdressing sib xyaw
Hais txog kev sib xyaw sib xyaw ntawm toescressing, tseem muaj ob txoj kev sib txawv: av saumrdressing thiab foliar toppressing.
Ua ntej, cov av sab saum toj txoj kev, cov sib tov sib xyaw yog 1.8% sodium nitrophenolates (5-10 ml / g) thiab 35 phaus ntawm urea. Cov mis no sib piv kuj yog li 1 evkawj. Av Topdressing siv qhov sib xyaw no, thiab nws raug nquahu kom siv cov txheej txheem kev thov faus, uas yuav muaj kev cuam tshuam zoo dua.
Thib ob, Foliar fertilizer aintizer txoj kev, cov sib tov sib xyaw yog: 1.8% sodium nitrophenolates (3 ml / 50 grams urea, thiab 60 kilo dej.
Txawm li cas los xij, txau yog nkag siab txog lub sijhawm kev loj hlob ntawm cov qoob loo, thiab nws yuav tsum tau siv rau lub sijhawm kev loj hlob zoo tshaj plaws rau cov txiaj ntsig zoo dua. Piv txwv li: nyob rau hauv theem ntawm yub, tawg paj thiab o theem, txau ib zaug hauv txhua lub sijhawm loj hlob yuav muaj kev cuam tshuam zoo dua ntawm kev nce qib kev loj hlob.
Ntsiab lus: Cov txiaj ntsig ntawm kev sib xyaw ua ke sodium nitrophenolates thiab urea yog cov ntsiab lus nitrogen, thiab sodium nitrophenolates yog ib qho kev daws teeb meem zoo rau cov nroj tsuag kev loj hlob. Cov kev sib xyaw ntawm kev siv urea thiab sodium nitrophenolates tuaj yeem nce cov photosynthetic tus nqi ntawm kev siv cov nitrogen fertilizer, thiab nce ntau lawm. Nws yog hu ua "Golden tus khub" lossis "Golden Formula" ntawm cov chiv thiab tshuaj tua kab.
