Nco ntsoov, tag nrho cov gardeners thiab tsheb ua liaj ua teb paub hais tias nyob rau hauv lub cultivation ntawm tag nrho cov nroj tsuag, ib tug obligatory mob yog kev taw qhia ntawm fertilizing. Nws yog ua tiav nyob rau hauv ntau txoj kev thiab nyob txawv sij hawm. Xws li noj thaum lub sij hawm nquag kev loj hlob ntawm cov nroj tsuag yuav tom qab them tawm nrog ib tug zoo kawg nkaus sau. Feem ntau, tej yam ntuj tso chiv (humus, quav ) thiab pob zeb hauv av chiv (nitrogen, potassium, phosphoric). Peb yuav qhia koj seb yuav siv cov tshuaj superphosphate thiab nws cov nyiaj pab rau cov nroj tsuag.
Superphosphate: muaj pes tsawg leeg
Superphosphate yog ib qho zoo heev nitrogen-phosphorus pob zeb hauv av fertilizer. Ntxiv rau cov phosphorus (26%) thiab nitrogen (6%), superphosphate muaj xws li microelements li potassium, magnesium, calcium thiab sulfur tsim nyog rau cov nroj tsuag kom noj thiab loj hlob. Qhov no chiv muaj nyob rau hauv daim ntawv ntawm ib lub hmoov thiab granules txog li 4 hli nyob rau hauv loj.
Muaj ntau yam ntawm fertilizer. Superphosphate yog ib qho yooj yim - haum zoo hmoov hmoov zoo, tab sis nws lub ntsiab tseem ceeb yog ib qho kev faib loj ntawm cov dej tsis muaj zog (li 40%). Qhov no tshuaj tsis pab cov nroj tsuag, tab sis gardeners yog yuam kom hnav hnyav packs rau supplementation. Tab sis lub tshuaj yog ib qho yooj yim mus siv thiab tsis khoom qab zib.
Txij ntawm qhov yooj yim, Superphosphate yog granulated nrog 30% cov ntsiab lus calcium sulphate. Muab ob npaug rau superphosphate los ntawm ib feem me me ntawm gypsum thiab ib feem ntawm cov phomphate ntau dua (txog li 50%) hauv qhov muaj pes tsawg leeg.
Superphosphate yog dab tsi?
Nyob rau hauv dav dav, phosphorus yog ib lub caij uas accelerates qhov kev hloov ntawm theem ntawm kev loj hlob ntawm seedlings mus rau fruiting theem. Tsis tas li ntawd, cov khoom ua tau zoo dua qhov palatability ntawm txiv hmab txiv ntoo ntawm orchards thiab Berry cov qoob loo. Phosphorus tshwm sim nyob rau hauv qhov nyob rau hauv daim ntawv ntawm cov organic thiab pob zeb hauv av compounds, tab sis nws digestibility rau nroj tsuag yog tsawg. Qhov no yog vim li cas ntxiv supplementation nrog superphosphate yog tsim nyog, ua tsaug rau uas:
- muaj ib txoj kev loj hlob ntawm lub hauv paus system;
- txhim kho qhov saj ntawm cov txiv hmab txiv ntoo;
- nce fertility;
- oxidative kev nyob rau hauv cov nroj tsuag muaj slowed down.
Yuav ua li cas ua kom superphosphate?
Qhov no phosphorus fertilizer yog siv rau txhua hom ntawm xau, tab sis nws tshwj xeeb kev ntsuas tau tiav nyob rau hauv nruab nrab thiab alkaline xau. Txawm li cas los, nyob rau hauv cov av nrog ib qho tshuaj tiv thaiv acid, phosphoric acid los ntawm superphosphate yog hloov mus rau hauv txhuas thiab hlau phosphates, sib txuas uas, hmoov tsis, tsis absorbed los ntawm cov nroj tsuag. Nyob rau hauv rooj plaub no, kev paub gardeners pom zoo kom tov lub tshuaj nrog limestone los yog humus.
Feem ntau cov kev siv ntawm superphosphate nyob rau hauv lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg yog siv rau kev khawb cov av thiab sowing cov qoob loo, thiab kuj raws li lub ntsiab pob zeb hauv av fertilizer rau bait noj. Feem ntau, rau cov qoob loo ntawm cov qoob loo xws li cov qos yaj ywm, txiv lws suav, beets, pob kws, dib thiab kom tau ib lub siab tawm los, nws yog feem ntau qhia kom ntxiv cov khoom thaum sowing ncaj qha mus rau hauv qhov dej.
Li ntawd, superphosphate daim ntawv thov kom yuav tsum tau txhaj cov tshuaj nram qab no:
- 40-50 g / m² thaum khawb hauv caij nplooj ntoos zeeg los yog caij nplooj ntoos hlav;
- thaum cog tubers thiab seedlings 3 g nyob rau hauv txhua tus zoo;
- 15-20 g / m² rau saum toj-hnav khaub ncaws nyob rau hauv qhuav daim ntawv;
- 40-60 g / m² nrog rau cov khoom noj ntawm cov ntoo.
Yuav ua li cas ua noj ib lub hood ntawm superphosphate?
Yuav kom accelerate lub caij ntawm fertilizer rau nroj tsuag, ntau gardeners-gardeners ua qhov kev txiav txim siab los npaj lub hood. Txawm li cas los, nws tsis yog yooj yim ua li no, raws li feem ntau lub gypsum nyob rau hauv lub npaj precipitates. Yog li ntawd, yog tias koj tseem raug teeb meem nrog rau lo lus nug ntawm yuav ua li cas dissolve superphosphate nyob rau hauv dej, peb pom zoo kom siv ib yam khoom nyob rau hauv daim ntawv ntawm granules rau qhov no. Rau ib liter ntawm dej kub nws yog ib qhov tsim nyog los noj 100 g ntawm ob superphosphate, sib tov zoo, boil rau ib nrab ib teev rau sai dissolution thiab lim. Nco ntsoov tias 100 ml ntawm no extract yog hloov nrog 20 g ntawm active khoom sib ua zaub mov. Yog hais tias cov 100 g yaj hauv 10 liv dej, lub resulting daws muaj peev xwm ua 1 square meter ntawm av.
