NDVI inomirira Normalized Difference Vegetation Index. Indekisi inowanzoshandiswa mukuona kure uye kurima kuongorora nekutarisa hutano uye simba rezvinomera.NDVIinoyera mutsauko uripo pakati pemabhendi matsvuku uye ari pedyo-infrared (NIR) emagetsi emagetsi, anobatwa nemidziyo yekunzwa iri kure senge satellite kana drones.

Iyo formula yekuverenga NDVI ndeiyi:

NDVI = (NIR - Tsvuku) / (NIR + Tsvuku)

Mune iyi fomula, iyo NIR bhendi inomiririra iri padyo-infrared kuratidza, uye Red bhendi inomiririra tsvuku. Hwaro hunobva pa -1 kusvika pa 1, hune hutsika hwepamusoro hunoratidza hutano uye huswa hwakanyanya, asi hutsika hunomiririra huswa hushoma kana ivhu risina chinhu.

Iyo NDVI ngano

NDVI yakavakirwa pamusimboti wekuti zvinomera zvine hutano zvinoratidzira zvakanyanya pedyo-infrared mwenje uye zvinotora dzvuku rakawanda. Nokuenzanisa mabhendi maviri e spectral,NDVIinogona kunyatsosiyanisa pakati pemhando dzakasiyana dzechivharo chevhu uye kupa ruzivo rwakakosha nezvehuwandu hwezvinomera, maitiro ekukura, uye hutano hwese.

Inoshandiswa zvakanyanya mukurima, masango, kutarisa kwezvakatipoteredza, uye mamwe minda kutarisa shanduko yezvinomera nekufamba kwenguva, kuongorora hutano hwezvirimwa, kuona nzvimbo dzakakanganiswa nekusanaya kwemvura kana chirwere, uye kutsigira sarudzo dzekutonga ivhu.

Maitiro ekushandisa NDVI mune zvekurima?

NDVI chishandiso chakakosha mune zvekurima chekutarisa hutano hwezvirimwa, kugadzirisa manejimendi ezviwanikwa, uye kuita sarudzo dzine ruzivo. Hedzino dzimwe nzira NDVI dzinogona kushandiswa mune zvekurima:

Crop Health Assessment:

NDVI inogona kupa ruzivo muhutano hwese uye kusimba kwezvirimwa. Nekugara uchitora NDVI data pamusoro pemwaka uri kukura, varimi vanogona kuona nzvimbo dzekushushikana kana kusakura zvakanaka kwezvinomera. Yakaderera NDVI kukosha inogona kuratidza kushomeka kwekudya, chirwere, kusagadzikana kwemvura, kana kukuvara kwezvipembenene. Kukasira kuona nyaya idzi kunoita kuti varimi vatore matanho ekugadzirisa, akaita semadiridziro akanangana, kuisa fetereza, kana kudzivirira zvipembenene.

Kushandiswa kweNDVI mune zvekurima

Yield Prediction:

NDVI data yakaunganidzwa mumwaka wese wekukura inogona kubatsira kufanotaura goho rezvirimwa. NokuenzanisaNDVIzvakakosha munzvimbo dzakasiyana-siyana kana matunhu mukati memunda, varimi vanokwanisa kuona nzvimbo dzine goho repamusoro kana rakaderera. Ruzivo urwu runogona kubatsira mukugonesa kugoverwa kwezviwanikwa, kugadzirisa density yekudyara, kana kushandisa nzira dzekurima nemazvo kuti uwedzere goho rose.

Irrigation Management:

NDVI inogona kubatsira mukugadzirisa maitiro ekudiridza. Nekutarisa kukosha kweNDVI, varimi vanokwanisa kuona mvura inodiwa nembesa uye kuona nzvimbo dzekudiridzira zvakanyanya kana zvishoma. Kuchengeta mwero wakakwana wehunyoro hwevhu zvichibva pane data reNDVI kunogona kubatsira kuchengetedza zviwanikwa zvemvura, kuderedza mari yekudiridza, nekudzivirira kushushikana kwemvura kana kudonha kwemvura muzvirimwa.

Fertilizer Management:

NDVI inogona kutungamira kushandiswa kwefetereza. Nekugadzira mamepu eNDVI pamunda wese, varimi vanogona kuona nzvimbo dzine zvinovaka muviri zvinodiwa. Yakakwira NDVI makoshero anoratidza hutano uye kukura zvine simba zvinomera, nepo yakaderera tsika inogona kuratidza kushomeka kwekudya. Nekushandisa mafetireza zvakanyatsoenderana neNDVI-inotungamirwa nemwero wekushandisa, varimi vanogona kuvandudza mashandisiro ezvinovaka muviri, kuderedza kupera kwefetereza, uye kukurudzira kukura kwechirimwa.

Kuongorora Zvirwere uye Zvipembenene:NDVI inogona kubatsira mukuona kwekutanga kwezvirwere kana kutapurira zvipembenene. Zvidyarwa zvisina hutano zvinowanzo ratidza zvakaderera NDVI hunhu zvichienzaniswa nezvinomera zvine hutano. Kugara tichitarisa NDVI kunogona kubatsira kuona dzingangove nzvimbo dzine dambudziko, zvichiita kuti kupindira panguva yakakodzera nemaitiro ekugadzirisa zvirwere kana nzira dzakanangwa dzekudzivirira zvipembenene.

Mepu yeMunda uye Zoning:NDVI data inogona kushandiswa kugadzira akadzama ezvinomera mamepu eminda, achibvumira varimi kuti vaone kusiyana kwehutano hwezvirimwa uye simba. Aya mamepu anogona kushandiswa kugadzira nzvimbo dzekutarisira, uko zviito zvakati, seyekusiyana chiyero chekushandiswa kwezvinopinza, zvinogona kuitwa zvichienderana nezvinodiwa chaizvo zvenzvimbo dzakasiyana mukati memunda.

Kushandisa nemazvo NDVI mune zvekurima, varimi vanowanzo vimba nehunyanzvi hwekunzwa kure, senge setiraiti mifananidzo kana madrones, akashongedzerwa nema sensors akawanda anokwanisa kubata anodiwa mabhendi ekuona. Maturusi esoftware maturusi anoshandiswa kugadzirisa uye kuongorora data reNDVI, zvichibvumira varimi kuita sarudzo dzine ruzivo nezvemabatiro ezvirimwa.

rudzii rwekamera lenzi dzakakodzera NDVI?

Kana uchitora mifananidzo yekuongorora NDVI, zvakakosha kushandisa chaiwo lenzi kamera akakodzera kutora anodiwa mabhendi ekuona. Heano marudzi maviri akajairika emalenzi anoshandiswaNDVIzvikumbiro:

Normal Visible Light Lens:

Iri rudzi rwelens rinotora inooneka spectrum (kazhinji kubva pa400 kusvika 700 nanometers) uye inoshandiswa kutora bhendi dzvuku rinodiwa pakuverenga kweNDVI. A standard inooneka mwenje lens inokodzera chinangwa ichi sezvo ichibvumira kutora inooneka tsvuku mwenje inotaridza zvirimwa.

Near-Infrared (NIR) Lenzi:

Kutora iyo iri pedyo-infrared (NIR) bhendi, iyo yakakosha pakuverenga kweNDVI, inodiwa NIR lens inodiwa. Iyi lenzi inobvumira kutora mwenje mupedyo-infrared renji (kazhinji kubva pa700 kusvika 1100 nanometers). Izvo zvakakosha kuve nechokwadi chekuti lenzi inokwanisa kunyatso tora iyo NIR mwenje pasina kusefa kana kuikanganisa.

Malenzi anoshandiswa kune NDVI maapplication

Mune zvimwe zviitiko, kunyanya kune inyanzvi yekunzwa kuremerwa application, multispectral makamera anoshandiswa. Aya makamera akashongedzerwa neakawanda sensors kana mafirita anotora chaiwo mabhendi ekuona, anosanganisira matsvuku uye NIR mabhendi anodiwa kuNDVI. Multispectral makamera anopa data rakawanda uye rakanyatsojeka rekuverenga kweNDVI kana ichienzaniswa nekushandisa akasiyana lenzi pane yakajairwa inoonekwa mwenje kamera.

Izvo zvakakosha kuti uzive kuti kana uchishandisa yakagadziridzwa kamera yekuongorora NDVI, uko kamera yemukati sefa yakatsiviwa kuti ibvumire kubatwa kweNIR, chaiwo lenzi akagadziridzwa kubata NIR mwenje anogona kunge asiri madikanwa.

Mukupedzisa, NDVI yakaratidza kuva chishandiso chakakosha pakurima, zvichiita kuti varimi vawane ruzivo rwakakomba nezvehutano hwezvirimwa, kugadzirisa zviwanikwa, uye kuita sarudzo dzinotungamirwa nedata. Nekuramba kuchiwedzera kudiwa kweiyo chaiyo uye inoshanda NDVI ongororo, zvakakosha kuve nemidziyo yakavimbika inobata anodiwa mabhendi ekuona nemazvo.

PaChuangAn, isu tinonzwisisa kukosha kweyemhando yepamusoro yekufungidzira tekinoroji muNDVI maapplication. Ndosaka tichidada kusuma yeduNDVI lenzies. Yakagadzirirwa kunyanya kushandiswa kwekurima, lens yedu inogadzirwa kuti itore mabhendi matsvuku uye ari pedyo-infrared nekujeka kwakasiyana uye nekujeka.

NDVI kamera kutendeuka

Inoratidzira yekucheka-kumucheto optics uye epamberi lens coatings, yedu NDVI lens inovimbisa kushoma kwechiedza kukanganisa, kuunza yakavimbika uye inowirirana mhedzisiro yekuverenga NDVI. Kuenderana kwayo neakasiyana makamera uye kubatana kwayo kuri nyore kunoita kuti ive sarudzo yakanaka kune vaongorori vezvekurima, maagronomists, uye varimi vari kutsvaga kukwidziridza ongororo yavo yeNDVI.

NeChuangAn's NDVI lens, unogona kuvhura kugona kwakazara kweNDVI tekinoroji, ichikupa simba rekuita sarudzo dzine ruzivo nezve manejimendi ekudiridza, kuisa fetereza, kuona chirwere, uye kugadzirisa goho. Sangana nemusiyano mukurongeka uye kuita neadu-ye-ye-iyo-inoyevedza NDVI lens.
