Chifukwa chakuti phulusa limathandiza sizitanthauza kuti liyenera kugwiritsidwa ntchito ku nthaka chaka chilichonse. Pano simungathe kuliposa. Sitikulimbikitsidwa kuti mugwiritse ntchito phulusa kunthaka popanda kuyang'ana acidity ya nthaka. Kufufuza kwa dothi kuyenera kuchitika zaka ziwiri zilizonse. Mitengo yambiri imakhala ndi dothi lochepa, choncho phulusa liyenera kuwonjezeka pokhapokha ngati dothi la m'mundamo liri lovuta kwambiri. Pewani kubweretsa phulusa pansi pa mbewu zomwe zimakonda dothi losavuta. Pakati pawo mukhoza kutcha radish, mbatata, mavwende, blueberries, rhododendrons, holly ndi azaleas.
Kuyezetsa magazi mosavuta kumachitika motere: Tengani nyemba zouma, moisten ndi madzi ang'onoang'ono osungunuka, ndipo sungani chidutswa cha pepala la litmus m'nthaka yosakaniza. Kusintha kwa mtundu wa pepala la litmus kumafaniziridwa ndi tebulo lopangidwa ndi pepala la litmus.
Phulusa lili ndi potaziyamu
Olima munda amayamikira komanso amagwiritsa ntchito phulusa ndi potaziyamu ndi laimu. Poyamba, nkhuni phulusa idatsukidwa ndipo zotsatira zake zinasinthika. Chombocho chinapangidwa ndi potaziyamu carbonate ndi mchere wina. Phulusa losasamba la nkhuni liri ndi zinthu zonse za mchere zimene zinali mumtengo. Ndicho chitsime chabwino cha potaziyamu, michere yomwe imapangitsa kuti zimayambira zitsamba zamphamvu ndi zosagwira ku malo ogona. Kuwonjezera apo, potaziyamu imapatsa zomera zamoyo, kukana matenda ndi nyengo yozizira hardiness. M'mbuyomu, phulusa la nkhuni linali gwero lalikulu la izi.
Phindu la phulusa limaphatikizapo potaziyamu yomwe ili m'kati mwake kuti iwononge kukula kwa mbewu zomwe zimayambitsa nayitrogeni komanso kuchepetsa kusamba msanga, zomwe zingayambitse phosphoric acid kwambiri. Pokhala mu chomera, potaziyamu ikuphatikizapo kupanga zakudya (photosynthesis) ndi kusintha kwawo kukhala wowuma. Potaziyamu imathandiza kwambiri kupanga mapuloteni a chlorophyll.
Kusowa kwa potaziyamu m'nthaka kumasonyeza maonekedwe a masamba a zomera. Popeza kuti potaziyamu imayenda m'mera kuchokera m'munsi mwa masamba mpaka pamwamba, ndiye kuti, pambali pake, masamba a m'munsi amawoneka achikasu, ndiye masambawo amakhala bulauni ndi kutenthedwa. Kuonjezerapo, pamunsi masamba akhoza kuoneka ngati tchire komanso chikasu.
Phulusa la hardwood lili ndi potaziyamu yambiri kuposa phulusa la miyala yofewa. Chidziwitso chakuti zothandiza zake ndizokokomeza, kuti ndizowonongeka ndi zovulaza zomera, si zoona. Zonsezi, ndi phulusa lina zimatha kubweretsa dothi la maluwa ndi minda ya khitchini. Koma mbatata sayenera kugwiritsidwa ntchito pachaka ku mbatata, chifukwa ikhoza kuyambitsa nthendayi - matenda omwe amapezeka m'matatato amachititsa kuti nthaka isaloĊµerere. Komabe, ndi bwino kuti chaka chilichonse apange phulusa pamapedi a maluwa ndi peonies, kuti aziphulika bwino.
Zomwe zili m'mitengo phulusa zimasungunuka m'madzi, choncho musapange zolakwika ndipo osasunga phulusa pansi pa thambo. Tifunika kuikha msangamsanga pamtunda wa kompositi kapena kuiyika pamtunda, kapena kuisungira pamalo ouma - mu galasi kapena kukhetsa. Ngati kusaka kwa nthaka kukuwonetseratu kuti dothi m'munda wanu ndi lokhazikika, perekani phulusa m'chaka, kugwa kapena yozizira pamtunda wa 2.5 makilogalamu pa 10 sq.m.
Kompositi ya phulusa
Phulusa la nkhuni ndi lothandiza mu mulu wa kompositi, kumene zipangizo zamkati zili ndi zidulo zambiri. Zilonda zamtundu wa kompositi zimatha pang'onopang'ono. Mafuta a phulusa akhoza kuchepetsa chilengedwe cha acidic cha kompositi. Koma ngati nthaka yanuyi ili ndi zamchere, musawononge kompositi ndi phulusa. Ngati manyowa sakutha, ammonia ambiri akhoza kumasulidwa, omwe angathe kupha kapena kuvulaza nthaka ndi zamoyo zothandiza m'dulu.
Chilengedwe ndi chopambana kwa iwo omwe amayendetsa bwino milu ya manyowa. Manyowa, tizilombo ta tizilombo ndi tizilombo tina tomwe timapuma, timalimbikitsa kuwonongeka kwa zinthu zakuthupi, kukhala m'nthaka, pamwamba pa zinyalala komanso ngakhale zonyansa. Phulusa la nkhuni limayambitsa madontho achilengedwe awa kuti asonyeze ntchito yaikulu pakuwonongeka kwa zinthu zakuthupi.
Ngati phulusa (kapena laimu) litayambika m'nthaka, zotsalira zamasamba, chifukwa cha ntchito ya tizilombo toyambitsa matenda, zimatha kuzizira mwamsanga ndipo zimakhala zakudya. Chifukwa cha kuchuluka kwa acidity ya sing'anga, tizilombo ting'onoting'ono tingasonyeze ntchito yochepetsedwa, ndipo dothi silikukwanira mokwanira phosphorous, nayitrogeni, calcium ndi magnesium, zofunika kwa zomera. Phulusa la nkhuni - chinsinsi cha zakudya za pantry kwa zomera.
Phulusa la udzu
Kugwiritsira ntchito phulusa pamtunda sikumangokhala m'munda yekha. Ndibwino kuti udzu udzuke. Phulusa labwino lopaka lili ndi laimu wambiri monga miyala yamtengo wapatali ya nthaka yomwe imathandizira kukonza udzu. Udzu wambiri umakula bwino pa dothi lokhala ndi asidi osalowererapo, chifukwa ndi acidity iyi imasonyeza kuti zakudya za nthaka zimakhala zofikira kwambiri kwa zomera, zimakhala zosavuta kuzigwira ndi mizu.
Udzu wa udzu wouma bwino (kapena walandira phulusa lalikulu la phulusa) dothi ndi loopsa kwambiri kuposa nthaka yowonjezereka, ndipo musalole kuti alowe kumudzi wawo wamsongole. Komabe, ngati udzu uli ndi namsongole, izi sizikutanthauza kuti dothi ndi losavuta ndipo phindu la phulusa limakhala lofunikira. Kukhazikika sizingatheke kukhala phokoso. Zimathandiza ngati njira yothetsera namsongole kokha ngati acidity ya nthaka ndi yaikulu kwambiri moti zomera silingalandire zakudya zomwe zili m'nthaka.
