Paj rwb ua ib qho tseem ceeb nyiaj ntsuab qoob loo thiab paj rwb textile kev lag luam raw cov ntaub ntawv raw, nrog rau qhov nce ntawm cov neeg nyob densely, paj rwb, grain thiab oilseed cov qoob loo thaj av kev sib tw teeb meem yog ntau thiab ntau hnyav, kev siv paj rwb thiab grain intercropping tau zoo alleviate lub contradiction ntawm cultivation ntawm paj rwb thiab grain cov qoob loo, uas yuav txhim kho cov productivity ntawm cov qoob loo thiab kev tiv thaiv ntawm ecological. Yog li ntawd, nws yog ib qho tseem ceeb heev kom sai thiab raug saib xyuas kev loj hlob ntawm paj rwb nyob rau hauv intercropping hom.
Multi-spectral thiab pom dluab ntawm paj rwb ntawm peb theem fertility tau txais los ntawm UAV-mounted multi-spectral thiab RGB sensors, lawv cov spectral thiab cov duab nta tau muab rho tawm, thiab ua ke nrog qhov siab ntawm paj rwb cog rau hauv av, SPAD ntawm paj rwb tau kwv yees los ntawm kev pov npav regression integrated kev kawm (VRE) thiab muab piv nrog peb cov qauv, xws li, RandomR Tree Regression (Random Regression). (GBR), thiab Txhawb Vector Tshuab Regression (SVR). . Peb tau soj ntsuam qhov kev kwv yees qhov tseeb ntawm cov qauv kev kwv yees sib txawv ntawm cov txheeb ze cov ntsiab lus chlorophyll ntawm paj rwb, thiab tshuaj xyuas qhov cuam tshuam ntawm qhov sib txawv ntawm kev sib tshuam ntawm cov paj rwb thiab cov taum pauv ntawm kev loj hlob ntawm paj rwb, thiaj li muab lub hauv paus rau kev xaiv ntawm qhov sib piv ntawm cov paj rwb thiab soybean thiab high-precision kwv yees ntawm paj rwb.
Piv nrog RFR, GBR, thiab SVR qauv, VRE qauv qhia qhov kev kwv yees zoo tshaj plaws hauv kev kwv yees paj rwb SPAD. Raws li VRE kwv yees tus qauv, tus qauv nrog ntau cov duab nta, pom cov duab nta, thiab cog qhov siab fusion raws li cov khoom siv tau muaj qhov tseeb siab tshaj plaws nrog rau kev ntsuas R2, RMSE, thiab RPD ntawm 0.916, 1.481, thiab 3.53, raws li.
Nws tau pom tias ntau qhov chaw cov ntaub ntawv fusion ua ke nrog kev xaiv tsa kev sib koom ua ke algorithm muab txoj hauv kev tshiab thiab zoo rau SPAD kwv yees hauv paj rwb.
