Paj rwb ua ib qho tseem ceeb nyiaj ntsuab qoob loo thiab paj rwb textile kev lag luam raw cov ntaub ntawv, nrog rau kev nce ntawm cov neeg nyob densely, paj rwb, grain thiab oilseed qoob loo thaj av kev sib tw teeb meem yog ntau thiab ntau hnyav, kev siv cov paj rwb thiab grain intercropping yuav zoo alleviate lub contradiction ntawm lub kev cog qoob loo ntawm cov paj rwb thiab cov qoob loo, uas tuaj yeem txhim kho cov khoom tsim tau ntawm cov qoob loo thiab kev tiv thaiv kev sib txawv ntawm ecological thiab lwm yam. 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 cov duab 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 paj hauv av, SPAD ntawm paj rwb yog kwv yees los ntawm kev pov npav kev sib koom ua ke kev kawm (VRE) thiab piv nrog peb tus qauv, xws li Random Forest Regression (RFR), Gradient Boosted Tree 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 chlorophyll cov ntsiab lus ntawm paj rwb, thiab txheeb xyuas qhov cuam tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov paj rwb thiab soybean ntawm kev loj hlob ntawm paj rwb, thiaj li muab lub hauv paus rau kev xaiv ntawm qhov sib piv ntawm intercropping. nruab nrab ntawm paj rwb thiab soybean thiab high-precision kwv yees ntawm paj rwb SPAD.
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.
