Ulimi ndi sayansi monga momwe zimakhalira moyo. Kusanthula dothi, chimodzi mwazinthu zofunika kwambiri pa sayansi iyi, kuli ndi gawo lofunikira. Tiyeni tilowe mkati ndikumvetsetsa chifukwa chake kuli kofunika kwambiri.
Kufunika Kounika Dothi Paulimi
Kusanthula nthaka ndi gawo lofunikira pazaulimi, zomwe zimakhudza mwachindunji kukula kwa mbewu ndi zokolola. Pomvetsetsa momwe nthaka ilili, alimi amatha kupanga zisankho zabwino kuti akolole bwino.
Kuyang'anitsitsa: Kodi Kusanthula Dongo ndi Chiyani?
Kusanthula dothi, pachimake chake, ndikuwunika zitsanzo za nthaka kuti zidziwe momwe zilili, mankhwala, ndi chilengedwe.
Mitundu Yowunika Dothi
Pali mitundu itatu yayikulu yosanthula nthaka - mankhwala, thupi, ndi zachilengedwe.
1. Chemical Analysis
Kusanthula kwamankhwala kumawunika zakudya zam'nthaka ndi pH, zomwe zimalola alimi kusintha kaphatikizidwe ka feteleza kuti mbewu zikule bwino.
2. Kupenda Thupi
Kuwunika momwe nthaka ikugwirira ntchito kumafuna kuwunika momwe nthaka imapangidwira komanso momwe nthaka imakhalira, zomwe zimakhudza kasungidwe ka madzi ndi kulowa kwa mizu.
3. Biological Analysis
Kusanthula kwachilengedwe kumayang'ana tizilombo tating'onoting'ono tanthaka, zomwe zimathandizira kwambiri pakuwola kwa zinthu zamoyo komanso kuzungulira kwa michere.
4. Zifukwa Zazikulu Zopangira Kusanthula Dongo
Kumvetsetsa momwe nthaka imakhalira kumathandiza m'njira zambiri.
5. Kasamalidwe ka Zakudya Zam'mera ndi Feteleza
Kusanthula dothi kumatsogolera alimi pakuwongolera feteleza ndikusintha kadyedwe ka mbeu pozindikira kuperewera kwa michere ndikuthandizira kugwiritsa ntchito feteleza.
6. Matenda ndi Kuwononga Tizirombo
Kupyolera mu kufufuza nthaka, alimi amatha kuzindikira tizilombo toyambitsa matenda m'nthaka, zomwe zimathandiza kuti matenda asamalidwe bwino komanso tizirombo.
7. Kukokoloka kwa Dothi ndi Kusamalira
Imathandiza pa ntchito yosamalira nthaka pothandiza alimi kumvetsetsa za kuthekera kwa kukokoloka kwa nthaka ndi kuchitapo kanthu popewa kukokolokako.
N'chifukwa chiyani tiyenera kuzindikira nthaka yaulimi?
Izi zili choncho chifukwa cha kusowa kwa chakudya Kusalinganika ndi kuthira feteleza pakati pa nthaka ndi feteleza mu ulimi wamakono.
Ndikofunika kuti mlimi agwiritse ntchito chowunikira nthaka poyeza kulondola kwa nthaka ndikusintha ulimi..
Nchifukwa chiyani pali kusalinganika pakati pa kuchuluka kwa michere m'nthaka ndi umuna?
Yankho lagona pa mfundo yakuti mbewu zosiyanasiyana zimatulutsa zakudya zosiyanasiyana m’nthaka, motero zimawononga nthaka yeniyeniyo.
Ngati feteleza wamtundu umodzi wokha atagwiritsidwa ntchito kuonjezanso, sizingatheke kubwezeretsanso michere m'nthaka. Ulimi wamakono
imalimbananso ndi zovuta monga kugwiritsa ntchito feteleza wocheperako kapena kugwiritsa ntchito feteleza mopitilira muyeso. Mchitidwe woterewu sungobweretsa chiwonongeko
komanso zimathandizira kuwononga chilengedwe komanso kuthekera, kuchepa kwa zokolola. Kuchuluka kwa feteleza kungapangitse kuti nthaka ikhale yolimba
ndi kukhudza kwambiri chitukuko chathu chamtsogolo chaulimi.
Ndiye tingatani kuti zinthu zisinthe? Ayenera detector nthaka. Chifukwa ungatithandize kudziwa bwino nthaka. Sikuti kudziwa za nayitrogeni, phosphorous, potaziyamu, organic matter, kutentha kwa nthaka ndi chinyezi, PH mtengo ndi kuzindikira zina za index ndizofunikiranso.
Kuyang'anira zinthu monga kutentha kwa nthaka ndi chinyezi ndikofunikira kuti mbewu ikhale ndi thanzi labwino. Ngati madzi a m'nthaka atsika kwambiri, photosynthesis - njira yomwe imathandizira kukula kwa zomera - ikhoza kusokonezedwa. Kusoŵa kwambiri kwa madzi kungayambitse imfa ya mbewu.
Kuchuluka kwa malo opanda kanthu a nthaka kumakhalabe kosasintha, madzi ndi mpweya zikudzaza malowa. Madzi akachepa kwambiri, mizu ya zomera imalephera kuyamwa madzi okwanira. Kutuluka kwa mpweya kumapangitsa zomera kutaya madzi ambiri, zomwe zimapangitsa kuti madzi asamawonongeke komanso kufa. Kupanda madzi kungathenso kuumitsa nthaka ndi kuichititsa kung’ambika, kuwononga dongosolo lake ndi chonde.
Zochepanthaka chinyezi ndi chinyezimilingo ingasokoneze kwambiri kukula bwino kwa mbewu. Komabe, madzi ochulukirapo amawononganso chimodzimodzi. Ngati nthaka ili ndi madzi ambiri, mpweya umatenga malo ochepa a nthaka. Izi zimakakamiza mizu ya chomera kuti isinthe kupita ku kupuma kwa anaerobic, njira yomwe imatulutsa mowa. Izi ndi poizoni ku mizu ndipo zimatha kuola mizu ndipo, zikavuta, mbewu kufa.
Momwe Kuwunika kwa Dothi Kumakhudzira Zokolola Zaulimi
1. Zokolola Zowonjezereka ndi Zabwino
Kupyolera mu kagwiritsire ntchito kadyedwe koyenera, kuunika nthaka kungathandize kuti zokolola za mbeu zikhale zabwino.
2. Kupititsa patsogolo Thanzi la Nthaka
Thanzi la nthaka ndi lofunika kuti ulimi ukhale wokolola kwa nthawi yaitali. Kusanthula dothi kumatha kuzindikira zovuta ndikuthandizira alimi kuchitapo kanthu kuti nthaka ikhale ndi thanzi.
3. Kulima Mokhazikika ndi Kusunga Chilengedwe
Pothandizira kuthira feteleza molondola komanso kulimbikitsa kusunga nthaka, kusanthula nthaka kumathandizira ulimi wokhazikika komanso kusungitsa chilengedwe.
4. Tsogolo la Kuwunika kwa nthaka mu ulimi
Pamene luso laumisiri laulimi likukula, momwemonso kusanthula nthaka kumakula. Ndi kukwera kwaulimi wolondola komanso deta yayikulu, kusanthula nthaka kukuyembekezeka kukhala kolondola
ndi kupezeka, zomwe zikuthandizira tsogolo lokhazikika laulimi.
Tsopano, ndikuganiza kuti mwamvetsa kufunika kwa chinyezi cha nthaka. Ponena za kukula kwa zomera. Osati chinyezi chokha. Kutentha koyenera ndikofunikanso. Oyenera nthaka kutentha ndi bwino kukula kwa zomera. Kutsika kwambiri kapena kutentha kwambiri sikuthandiza kukula kwa mbewu. Mbewu ya mbewu iyenera kumera pamalo oyenera kutentha kwa nthaka. Mkati mwa kutentha kwina, pamene nthaka ikutentha kwambiri, mbewu zimakula mofulumira. Zomera zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana za kutentha. Kuwunika kwa kutentha kwa nthaka kumapangitsa kuti mbewu zikule pa kutentha koyenera kuti ziwonjeze kukolola.
Kutentha kwa chinyezi m'nthaka kumagwira ntchito yofunika kwambiri pakukula kwa mbewu. Kuyesedwa pafupipafupi ndikofunikira. Kutentha kwa nthaka ndi sensa ya chinyezi ndi chida chapamwamba chodziwira kutentha ndi chinyezi. Thesensor kutentha ndi chinyeziamagwiritsa ntchito kafukufuku wophatikizika wa kutentha ndi chinyezi ngati chinthu choyezera. Zizindikiro za kutentha ndi chinyezi zimasonkhanitsidwa ndikusinthidwa ndi kusefa kwamagetsi okhazikika, kukulitsa magwiridwe antchito, kuwongolera kopanda mzere, kutembenuka kwa V / I, mabwalo achitetezo apano komanso obwerera kumbuyo.
Kutulutsa kwa siginecha yapano kapena yamagetsi kumasinthidwa kukhala mgwirizano wamzere wa kutentha ndi chinyezi. Kutulutsa kwa 485 kapena 232 kumapezekanso kudzera pa chipangizo chachikulu chowongolera. Poyezera kutentha kwa nthaka ndi chinyezi, chopendekeracho chizikidwe mozama momwe tingathere m'nthaka, ndipo chofufuziracho chisungike pafupi ndi 1cm kuchokera pansi kuti muyeso ukhale wolondola.
Zinthu zambiri zidzakhudza kulondola kwa kuyeza, thekufufuza chipolopoloilinso ndi chikoka chachikulu pachitetezo komanso kuthekera kwa mpweya kwa gawo la PCB. Nyumba zosefera zosapanga dzimbiri zimatha kuteteza PCB efficient. HENGKO kutentha ndi chinyezi sensor nyumba ndi yolimba, motetezeka komanso moyenera kuteteza ma module a PCB kuti asawonongeke, mwayi waukulu wa fumbi, anti-corrosion ndi madzi. Kufikira mulingo wa chitetezo cha IP65, gawo la sensor ya chinyezi limatha kutetezedwa bwino ku fumbi, kuipitsidwa ndi tinthu tating'onoting'ono komanso makutidwe ndi okosijeni amankhwala ambiri, kuwonetsetsa kuti ntchito yake yanthawi yayitali yokhazikika, pafupi ndi moyo wazongopeka wa sensa.
Mapeto
Kumvetsetsa nthaka posanthula ndikofunika kwambiri kuti ulimi ukhale wopambana.
Pamene tsogolo laulimi likulumikizana kwambiri ndi luso lamakono, kufufuza nthaka kudzakhala kovuta kwambiri kuposa kale lonse.
FAQ
