Zoonadi, alimi onse ndi amalimoto amadziwa kuti kulima zomera zonse, chikhalidwe choyenera ndicho kuyamba feteleza. Zimakwaniritsidwa m'njira zosiyanasiyana komanso nthawi zosiyanasiyana. Kudyetsa chakudya panthawi ya kukula kwa mbeuyo kudzabwezeredwa ndi zabwino zokolola. Kawirikawiri, feteleza zachilengedwe (humus, manyowa ) ndi mineral feteleza (nayitrogeni, potaziyamu, phosphoric) amagwiritsidwa ntchito. Tidzakuuzani momwe mungagwiritsire ntchito superphosphate ndi mapindu ake kwa zomera.
Superphosphate: zolemba
Superphosphate ndi feteleza kwambiri ya nitrogen-phosphorous feteleza. Kuphatikiza pa phosphorous (26%) ndi amtrojeni (6%), superphosphate imakhala ndi potaziyamu, magnesium, calcium ndi sulfure zofunikira kuti zomera zizidyetsa ndi kukula. Manyowawa amapezeka ngati mawonekedwe a ufa ndipo amapanga 4 mm kukula.
Pali mitundu yosiyanasiyana ya feteleza. Superphosphate ndi yophweka - yokonzekera bwino, koma yokoka kwake ndilo lalikulu la madzi osasunthika (mpaka 40%). Thupili silimapindulitsa zomera, koma wamaluwa amakakamizika kuvala katundu wolemetsa kwa supplementation. Koma mankhwalawa ndi osavuta kugwiritsa ntchito ndipo sakhala ndi keke.
Kuchokera posavuta, Superphosphate ndi granulated ndi 30% ya calcium sulphate. Double superphosphate imadziwika ndi timadzi tochepa tomwe timapanga tizilombo toyambitsa matenda komanso chiwerengero chachikulu cha phosphate (mpaka 50%).
Kodi superphosphate imagwiritsidwa ntchito?
Kawirikawiri, phosphorous ndi chinthu chomwe chimafulumira kusintha kuchokera ku gawo la kukula kwa mbande ku fruiting gawo. Kuonjezerapo, mankhwalawa amathandiza kuti zipatso za zipatso ndi mbewu za mabulosi zikhale bwino. Phosphorus ilipo m'chilengedwe monga mawonekedwe a organic ndi amchere, koma kuchepa kwa zomera ndi kochepa. Ichi ndi chifukwa chake zina zowonjezerapo ndi superphosphate ndizofunika, chifukwa:
- pali chitukuko cha mizu;
- kusintha kukoma kwa zipatso;
- kubeleka kochuluka;
- Njira zowonjezereka m'mitengo zimachepa.
Kodi mungapange bwanji superphosphate?
Manyowa a phosphorous amagwiritsidwa ntchito pa mitundu yonse ya dothi, koma mphamvu yake yapadera imapezeka mu nthaka yopanda ndale. Komabe, mu dothi ndi asidi, phosphoric acid kuchokera ku superphosphate imasandulika aluminium ndi zitsulo zakutchire, mankhwala omwe, mwatsoka, samakhala ndi zomera. Pankhaniyi, olima wamaluwa amalimbikitsidwa kusakaniza mankhwalawa ndi miyala yamchere kapena humus.
Nthawi zambiri ntchito ya superphosphate m'chaka ndi m'dzinja imagwiritsidwa ntchito polima nthaka ndi kubzala mbewu, komanso monga feteleza wamkulu wa mchere. Kwenikweni, pofuna kulima mbewu monga mbatata, tomato, beets, chimanga, nkhaka ndi kupeza chokolola chochuluka, nthawi zambiri amalangizidwa kuwonjezera chinthucho pofesa mwachindunji m'mitsitsi.
Choncho, ntchito ya superphosphate imafuna izi:
- 40-50 g / mamita pamene akumba mu kugwa kapena kasupe;
- pamene mubzala tubers ndi mbande 3 g muzitsulo iliyonse;
- 15-20 g / mamita okwera mmwamba mmwamba mu mawonekedwe owuma;
- 40-60 g / m² ndi nyambo ya mitengo yamaluwa.
Kodi kuphika hood kuchokera ku superphosphate?
Kuti apititse patsogolo feteleza kwa mbeu, amaluwa ambiri amaluwa amasankha kukonzekera. Komabe, si zophweka kuchita izi, nthawi zambiri gypsum mukukonzekera. Choncho, ngati inunso muli ndi funso la momwe mungasungunulitsire superphosphate m'madzi, timalimbikitsa kugwiritsa ntchito chinthu monga granules pa izi. Kwa lita imodzi ya madzi otentha m'pofunika kutenga 100 g ya double superphosphate, sakanizani bwino, wiritsani kwa theka la ora kuti muwonongeke mofulumira ndi mavuto. Kumbukirani kuti 100 ml ya mcherewu amalowetsedwa ndi 20 g wa mankhwala othandizira. Ngati 100 g amasungunuka mu 10 malita a madzi, zotsatira zake zimatha kupanga mita imodzi ya dothi.
