Kuchuluka kwa acidity m'nthaka kumadetsa zomera ndikuphwanya zomera. Pali gulu laling'ono la zomera zomwe zimakula bwino pa dothi lolimba kwambiri, mwachitsanzo, cranberries. Koma makamaka zomera zomera amakonda sing'anga ndi wofooka asidi dothi. Kuonjezerapo, dothi la asidi limauma bwino, ndipo limauma, limakhala ndi chipsinjo cholimba. Kuti asamapangitse asidi omwe ali m'nthaka, liming ya nthaka ikuchitika. Kuonjezera apo, dothi la dothi lokhazikika limapangitsa kuti zakudya zamasamba zikhale bwino, chifukwa cha kukula kwa mizu yamphamvu kwambiri yomwe ikukula m'dziko losakhala lachilendo.
Zinthu zotchedwa calcareous
Zida zapachilengedwe (chimwala, dolomites, marl) ndi laimu zomwe zimakhala ndi zipangizo zamakono (shale ash, simenti, phala, sludge) amagwiritsidwa ntchito. Zinthu zonsezi zimakhala ndi zokopa kapena calcium carbonate mosiyana. Koma ndi chiyani chomwe chili chabwino kupatula nthaka? Alimwa omwe ali ndi zaka zambiri akulangizidwa kuti agwiritse ntchito feteleza opangidwa ndi mafakitale, omwe magawo 10 a kashiamu amakhala ndi magawo 4 mpaka 8 a magnesium. Kuyamba kwa zovuta zomwe zimapanga zonsezi kumalimbikitsa kuwonjezeka kwa zokolola za mbewu zochuluka kuposa momwe zimagwirira ntchito feteleza popanda magnesium.
Kuthamanga kwa liming
Agrotechnics akulimbikitsidwa kuti azipanga nthaka ya dacha kamodzi pa zaka 6 mpaka 8, chifukwa chifukwa cha zomwe zimachitika m'nthaka, momwe chilengedwe chikuyendera pang'onopang'ono, kubwerera zaka zingapo kumayambiriro oyambirira.
Kodi mungadziwe bwanji kuti nthaka ikufunika kuchepetsa chiyani?
Nthaka imakhudzidwa ndi laimu, kutsogoleredwa ndi zizindikiro zakunja za dziko lapansi. Choyamba, dothi lolimba kwambiri ndi dothi loyera kapena la imvi loyera komanso lopangidwa ndi podzolic ndi makulidwe oposa 10 masentimita amafunika kuika malire. Kufunika kwa kuchepa kumatsimikiziridwa ndi dziko la zomera zomwe zimalima komanso kukula kwa udzu. Kutsimikizika kwapadera kwa acidity kumapezeka tirigu, clover ndi beet, kukula kwawo kosauka kumatsimikizira kuti nthawi yomweyo nthaka imakhala yofunika. Namsongole amakula bwino pa dothi la asidi. Kukula kwa heather, Ledum, zokwawa za buttercup, pike, sorrel kumasonyezanso kuti nthaka imakhala yochuluka kwambiri. Pogulitsa pali zizindikiro za pepala zomwe zimathandiza kuti zikhoze kuwulula zomwe zili mu asidi pansi.
Ndiyenera kupanga liti?
Poyamba, laimu imagwiritsidwa ntchito poika munda pamakonzedwe a malo. Kenaka njira yogwiritsira ntchito feteleza yamakona imapangidwa kumayambiriro (autumn) dziko lisanakhazikitsidwe.
Mlingo umene laimu umagwiritsidwa ntchito kunthaka
Mlingo woyenera kugwiritsa ntchito hydrated laimu pa nthaka umadalira:
- uchimo wa dziko lapansi;
- nthaka;
- mitundu yosiyanasiyana ya feteleza yamakono yogwiritsidwa ntchito;
- kuya kwake.
Ndi acidity mkulu, laimu ndi jekeseni padziko lapansi mu mlingo waukulu. Ndi mchere wamphamvu kwambiri, 0,5 makilogalamu a miyala yamakono pa 1 m2 imagwiritsidwa ntchito mu dongo ndi nthaka ya loamy, 0,3 makilogalamu ndi dothi la mchenga. Pakati pa acidity - motero 0.3 kg ndi 0.2 kg. Powonjezera acidity - dothi ndi loamy 0,2 makilogalamu amayamba, dothi lachinyontho silimy.
Kodi mungapange bwanji laimu m'nthaka?
Kawirikawiri wamaluwa samadziwa bwino bwino nthaka. Limu losayembekezeka limakhala phulusa komanso lopanda madzi kuti lizimitse. Msuzi wofiira wothira palimodzi nthawi yomweyo wothira pansi. Kulimbikitsana kwa mandimu ndi dothi ndi chinthu chofunika kwambiri kuti mukhale ndi malire abwino.
Ntchito pa mphutsi za nthaka
Nkhono zapansi sizimera bwino mu dothi la asidi, kotero kuchitira nthaka ndi mandimu m'zinthu zomwe zasonyezedwa, zimapindulitsa anthu okhala ndi zamoyo zopindulitsa.
