The plants growth included photosynthesis, photo morphogenesis, photoperiod adjusting and light intensity selectivity with spectrum. Multi-LED lighting for strawberry mainly confirms the main spectrum to match emission spectrum with the selective absorption spectrum of plants; Matching a variety of appropriate wavelength LED; The present system simulated sunlight from the visible light range to the...
Based on the spectral analysis technology, agronomic parameter estimation which can obtain information on crop growth and nutrition, is efficient technology guarantee for the development of precision agriculture. On the basis of introducing the crop spectral theory, from mechanism model, experience and mechanism combination model, empirical model three parts, the research progress on agronomic parameter...
