通过对稻株(含叶片)含氮量、叶面积指数、光谱变量与水稻产量结构间的相关分析,建立了单产光谱模式[y产量=A+B(RVI)+C(RVI)~2]和最佳单产农学光谱模式[LAI=A+B(RVI)+C(RVI)~2];[y产量=A+B(LAI)+C(LAI)~2]。由于仅是试验模式,故扩大应用时还需通过田间试验作修正。
Through the correlation analysis of rice nitrogen content, leaf area index, spectral variables and rice yield structure, the yield spectrum model [y yield = A + B (RVI) + C (RVI) And the best yield agronomic spectral model [LAI = A + B (RVI) + C (RVI) ~ 2]; [y production = A + B (LAI) + C (LAI) ~ 2]. Since it is only a test mode, it needs to be amended through field trials to expand the application.
