Qee lub sij hawm txawm tias zoo-groomed lub caij ntuj sov tsev yuav poob lawv cov duab: lawv wither, thiab cov nplooj ua xiav-violet. Hauv qhov no, kev siv superphosphate fertilizer yog qhov tsim nyog.
Phosphorus yog cov khoom tsim nyog txhawm rau txhawm rau ua haujlwm li qub thiab tsim kho cov ntoo. Lub ntuj nyob ntawm cov av nrog qhov siv tau qhov tseem ceeb tsuas yog 1%, thiab txawm tias muaj tsawg dua cov khoom sib txuas nrog nws.
Phosphorus muaj kev koom tes rau hauv cov txheej txheem lub zog ntawm cov metabolism, muab khoom noj khoom haus rau cov nroj tsuag hlwb, thiab hauv photosynthesis. Vim tias qhov no, cov khoom lag luam nce ntxiv, thiab cov nroj tsuag tau txais lub zog rau kev loj hlob sai.
Superphosphate fertilizer yog tsim raws kev tsim ntawm phosphorus-nitrogen compound, nyob rau hauv kev sib xyaw nrog kab kawm thiab cov ntxhia pob zeb. Qhov no muaj pes tsawg leeg yog khov nrog ntau yam tshuaj tsim nyog rau kev loj hlob zoo thiab kev loj hlob ntawm cov txiv ntoo.
Universal fertilizer superphosphate pab txhawm rau nce cov txiaj ntsig. Cov txheej txheem nyuaj ntawm microelements ua kom tiav cov txheej txheem tawg paj thiab kev txhim kho tag nrho ntawm cov hauv paus hniav thiab tua, thiab tseem muab cov tshuaj kho thiab tiv thaiv ntau yam kab mob.
Hom ntawm chiv
Cov tshuaj phosphorus-nitrogen ntau ntau muaj ob lub ntsiab:
- Yooj yim superphosphate. Qhov siab ntawm phosphorus nyob rau hauv cov chiv yog mloog txog 25%, nitrogen - txog li 8%, leej faj - txog 10% thiab calcium sulfate (gypsum) ntawm 40%. Ntawm kev muag, superphosphate yooj yim muaj nyob rau hauv ob daim ntawv: hmoov thiab granules.
- Ob chav superphosphate. Raws li, nws muaj ob zaug ntau tshaj li phosphorus (45-55%). Lub peev xwm nitrogen yog 17%, thiab leej faj - 6%. Ob chav superphosphate yog tsim tawm tshwj xeeb hauv cov granules uas yaj yooj yim hauv dej ntshiab.
Lub xub ntiag ntawm cov ntaub ntawv sib txawv ntawm cov chiv no tso cai rau koj siv nws rau qee hom nroj tsuag, ntau hom av thiab hauv ntau theem ntawm kev paub tab.
Yuav thov li cas superphosphate yooj yim
Txhawm rau kom ua tiav qhov txiaj ntsig siab, nws yuav tsum paub txoj ntsiab cai ntawm kev sib cuam tshuam thiab qhov tsim nyog muaj feem rau cov nroj tsuag tshwj xeeb lossis cov qoob loo cog qoob loo. Kev siv ntawm superphosphate fertilizer yog qhia tau ntawm kev ntim khoom lossis hauv cov lus qhia txuas nrog.
Qhov yooj yim thiab ob chav muaj pes tsawg leeg ntawm cov khoom siv thoob ntiaj teb, nyuaj phosphorus-nitrogen fertilizer siv tau thaum cog cov noob ntoo lossis noob nyob hauv ib qho av. Tsis muaj kev txwv rau cov qoob loo hauv lub vaj thiab cov ntoo ntawm cov ntoo kuj tsis muaj.
Txawm li cas los xij, thaum ua ntawv thov cov chiv no, koj yuav tsum coj mus rau hauv tus account me me nuance - superphosphate weakly ua nyob rau hauv acidic xau.
Yog li hais tias cov chiv tsis plam nws cov khoom noj khoom haus zoo, nws yog qhov tsim nyog yuav tsum deoxidize cov av nrog ntoo tshauv lossis kua txiv qaub sib xyaw (500 ml ntawm txiv qaub lossis 0.2 kg ntawm cov hmoov tshauv yuav tsum tau muab xam rau 1m2 av).
Cov txheej txheem ua kom tiav deoxidation siv sijhawm ntev. Tom qab ib hlis, superphosphate tuaj yeem siv rau hauv av. Tsuas yog tom qab lub sijhawm no, tsis yog nyuam qhuav pib. Txoj hauv kev qhia cov superphosphate yooj yim yog ncaj qha mus pw tsaug zog hauv kab lossis lub qhov rau khawb lossis cog. Cov neeg nyob rau lub caij ntuj sov pom zoo tam sim ntawd tom qab thov cov chiv rau kom cog noob.
Yooj yim superphosphate yog siv dav rau fertilizing xoob xoob, av xuab zeb, av podzolic. Nroj tsuag uas noj ntau leej faj (turnips, qos yaj ywm, beets, flax, carrots, radishes, qij ntawm cov nroj tsuag) muaj kev loj hlob zoo heev thiab kev loj hlob sai.
Nco ntsoov tias thaum ua haujlwm nrog superphosphate, nws yog txwv tsis pub tsim cov khoom sib xyaw ntawm ammonium nitrate, chalk, kua qaub, urea.
Superphosphate yog ib qho kev ywj pheej ntawm thoob ntiaj teb uas tau txais los ntawm cov khoom siv ntuj tsim (ua kom tsiaj ntawm pob txha tsiaj thiab hlau ore slag). Nws siv tau yog ua tau tsuas yog ua raws li cov lus pom zoo los ntawm cov kws tshwj xeeb.
Cov lus qhia rau kev siv superphosphate
Muab ob npaug rau superphosphate fertilizer yog siv rau cov av hauv lub caij nplooj ntoo hlav ua ntej cog, lossis thaum lub caij nplooj zeeg, tom qab sau qoob. Phosphorus yuav tsum muaj sijhawm los siv av. Nyob rau hauv lub sijhawm nruab nrab ntawm lub ntsiab ntawm cov chiv nkag, nws tseem pom zoo kom muab dej rau cov nroj tsuag txog ob zaug.
Superphosphate fertilizer, cov lus qhia rau kev siv:
- Cov kev siv niaj hnub ua ke ntawm ob chav superphosphate yog ua tiav zoo tshaj plaws nrog lub noob nplej, vim nws zoo li granules;
- Lub ntsiab daim ntawv thov ntawm ob superphosphate yuav tsum tau nqa tawm ua ntej sowing vaj cov qoob loo. Qhov no feem ntau tau ua nyob hauv kev laij. Los ntawm thawj daim ntawv thov, ntau txheej chiv tsis tau ntxuav tawm los ntawm dej los yog dej nag thiab tsis poob qis dua cov noob txheej;
- Kev siv ntawm cov hau kev ntawm phau ntawv tawg ntawm cov pob zeb tsis zoo, vim tias cov chiv no yuav tsum tau nyob ze rau lub hauv paus system ntawm cov qoob loo;
- Coob tus neeg nyob hauv lub caij ntuj sov siv ob zaug superphosphate sib txuas nrog cov nitrogen-potash thiab potash chiv, uas tau thov rau lub caij nplooj ntoo hlav thiab, raws li, lub caij nplooj zeeg.
Rau yub ntawm cov zaub thiab zaub ntsuab, 30 g txog 40 g ib square 'meter' ntawm ob superphosphate yog nkag mus rau hauv av. Txhawm rau pub vaj txiv ntoo hauv lub caij nplooj zeeg, txog li 600 g ntawm ob chav superphosphate rau 1 m2 yuav tsum ntxiv rau hauv av. Rau yub thiab nroj tsuag hauv tsev ntsuab thiab tsev cog khoom 100 g / 1m yog siv2Cov. Nws yog ib qho tsim nyog yuav tsum tau ntxiv 4 g ntawm ob chav superphosphate mus rau cov qos yaj ywm ditch. Xws li cov av xau, cov av yuav tsum tau nce ntxiv li 30%.
Cov tub ntxhais hluas yub thiab cov ntoo ntawm cov ntoo thiab cov hav txwv tshwj xeeb tshaj yog nyob rau hauv kev xav tau ntawm kev noj haus thiab chiv, vim tias tsis muaj lwm txoj hauv kev kom tau txais cov tshuaj tseem ceeb. Kev ua lag luam niaj hnub no muaj ntau yam kev qhia paub ntawm cov khoom noj khoom haus, thawj ntawm yog superphosphate.
