Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] see figure 1 The portable instrument for measuring the relative content of pigments (including chlorophyll and carotenoids, etc.) in plant leaves in the present invention mainly includes: a multi-wavelength semiconductor diode emitting light source 1, a leaf clamp 2, a plant leaf to be measured 3, and a wavelength selective receiver 4 , a single-chip computer 5 and a rechargeable battery pack 6 .

[0027] figure 2 In the decoder U1 receives from Figure 9 The P1.2, P1.1 and P1.0 encoding control signals of the host chip U5 (8031), the output signals of the decoders Y1~Y5 are level-inverted by the inverter U2, and the semiconductor diode drive circuit is Sequence lighting controls. The semiconductor diode drive circuit is a 6-way driver with the same structure, and only the first one driven by Y1 is introduced below: the high-level signal of Y1 cau...

Abstract

The related portable detector plant fin pigment comprises: a semiconductor diode emission source, a receiver, a SCM, and a cell. This invention can detect the relative content of chlorophyll and carotenoid without damage, benefit to learn exterior condition variation, and thereby provides data for scientific research.

Description

technical field [0001] The invention relates to a portable instrument for measuring the relative content of pigments (including chlorophyll, carotenoid, etc.) in plant leaves. Background technique [0002] Precision agriculture requires the ability to accurately grasp the temporal and spatial evolution of climate and soil, as well as its impact on crop growth, so that it can use fertilizers, pesticides and other cultivation management methods to carry out efficient agricultural management and management, and reduce agricultural production. pollution, and then achieve the goal of increasing production profits and protecting the ecological environment, so that agriculture can develop sustainably and healthily. For this reason, it is necessary to detect the growth status of crops in real time, and analyze the causes of adverse conditions, so as to take corresponding measures. Traditional methods of sampling, sample preparation and laboratory analysis are harmful to crops and a...
