Donje sechirimwa chakakosha chemari uye machira edonje indasitiri yezvigadzirwa, nekuwedzera kwenzvimbo dzine vanhu vakawanda, dambudziko remakwikwi evhu redonje, zviyo nembesa dzembesa riri kuramba richikura, kushandiswa kwedonje nekudyara zviyo kunogona kudzikamisa kupokana pakati penyika. kurimwa kwedonje uye zvirimwa zvezviyo, izvo zvinogona kuvandudza kubereka kwechirimwa nekuchengetedzwa kwezvakasiyana-siyana zvezvisikwa nezvimwe zvakadaro. Nokudaro, zvakakosha zvikuru kukurumidza uye kunyatsocherechedza kukura kwekotoni pasi pe intercropping mode.
Multi-spectral uye inooneka mifananidzo yekotoni pamatanho matatu ekubereka yakawanikwa neUAV-yakaiswa multi-spectral uye RGB sensors, yavo spectral uye mifananidzo yemifananidzo yakabudiswa, uye yakabatanidzwa nekukwirira kwemiti yekotoni pasi, SPAD yekotoni yaive. inofungidzirwa nekuvhota kudzoreredza kudzidza kwakabatanidzwa (VRE) uye kuenzaniswa nemhando nhatu, dzinoti, Random Forest Regression (RFR), Gradient Boosted Tree Regression (GBR), uye Support Vector. Muchina Kudzora (SVR). . Takaongorora huchokwadi hwefungidziro yemhando dzakasiyana dzefungidziro pahukama hwechlorophyll yedonje, uye tikaongorora mhedzisiro yezvikamu zvakasiyana zvekurima pakati pedonje nesoyabhinzi pakukura kwedonje, kuitira kuti tipe hwaro hwekusarudzwa kwereshiyo yezvirimwa zvakasanganiswa. pakati pedonje nesoyabhinzi uye fungidziro yepamusoro yedonje SPAD.
Kuenzaniswa neRFR, GBR, uye SVR modhi, iyo VRE modhi yakaratidza yakanakisa fungidziro mhedzisiro mukufungidzira donje SPAD. Zvichienderana nemhando yekufungidzira yeVRE, modhi ine maficha emifananidzo yakawanda, maficha anooneka, uye kureba kwechirimwa semapupu aive nehunyanzvi hwepamusoro netest set R2, RMSE, uye RPD ye0.916, 1.481, uye 3.53, zvichiteerana.
Yakaratidzwa kuti yakawanda-source data fusion yakasanganiswa nevhoti regression integration algorithm inopa nzira itsva uye inoshanda yekufungidzira kweSPAD mukotoni.
