Description
Technical field: [0001] The invention relates to an airborne plant spectrum rapid measurement system, in particular to an airborne or hand-held rapid measurement of field plants and estimation of crop nitrogen nutrition. Background technique: [0002] Nitrogen nutrition plays a key role in determining the photosynthetic capacity of plants in natural and agricultural environments (Abrol, et al., 1999). Nitrogen provides important support for plant photosynthesis and ecosystem productivity, and is one of the most important nutrients for crops. important nutrient. Nitrogen is the main nutrient element in the three nutritional elements of rice, and it plays an important role in the biosynthesis of amino acids, proteins, nucleic acids, chlorophyll and enzymes. Nitrogen exists as a limited resource in many systems (Field.Et al., 1986, Lee.et al., 1983, Shouichi, et al., 1981), so how to manage nitrogen and improve nitrogen use efficiency is very important Significant. General f...
