Method for Determination of Moisture Content of Miscanth Leaf

Abstract

The invention discloses a method for determining the water content of a Miscanthus plant leaf. The method sequentially comprises the following steps: 1, collecting a Miscanthus plant leaf to be determined; 2, scanning the Miscanthus plant leaf in a near infrared spectral waveband of 400-2500 nm to obtain the reflection spectra in the following 23 characteristic wavelengths: 486 nm, 554 nm, 624 nm, 676 nm, 694 nm, 714 nm, 772 nm, 912 nm, 958 nm, 1098 nm, 1322 nm, 1392 nm, 1432 nm, 1520 nm, 1642 nm, 1870 nm, 1900 nm, 2038 nm, 2122 nm, 2214 nm, 2274 nm, 2316 nm and 2404 nm; and 3, substituting above data to a water content calculating formula in order to obtain the water content of the Miscanthus plant leaf to be determined.

Description

technical field [0001] The invention relates to a method for measuring the moisture content of leaves of miscanthus plants. Background technique [0002] Miscanthus plants have been listed as important biomass energy crops in the world. At present, Miscanthus plants are often planted in water-deficient or saline-alkali land. Water shortages often occur in Miscanthus plants in these areas, which directly affects their biochemical processes and morphological structures. The water content directly shows the nutritional stress, drought stress, pest damage and aging process of Miscanthus plants in the growth process. Monitoring the water content of miscanthus leaves is of great significance in its growth, nutrition and resistance detection. [0003] The common method for detecting the moisture content of plant leaves is the drying constant weight method (national standard). This process needs to pick leaves and dry them to constant weight, which not only destroys the leaves but ...

Problems solved by technology

[0003] The common method for detecting the moisture content of plant leaves is the drying constant weight method (national standard). This process needs to pick leaves and dry them to constant weight, which not only destroys the leaves but also takes too long, so it is not suitable for rapid and nondestructive detection of plant leaf moisture. content
