Embodiment 1

[0028] 1. Materials

[0029] 10 pieces of tea tree leaves were taken from the tea tree germplasm resources nursery of the Tea Research Institute of Fujian Academy of Agricultural Sciences, A4 paper and inkpad.

[0030] 2. Method

[0031] 2.1 Paper selection processing

[0032] Randomly select 100 sheets of A4 paper (the paper area parameter is 21cm×29.8cm), measure the weight with an analytical balance (Max210g d=0.001g) produced by Mettler-Dolito (Shanghai) Co., Ltd., and select a weight difference of less than 0.02g The 30 sheets of paper are measured with a vernier caliper to measure the superimposed thickness, and measure the total thickness h. according to the formula Available paper density ρ=0.7333g / cm 3 . It can be seen that the calculation formula of the leaf surface to be tested is s = m ρh = 100 . m 0.7333 ...

Abstract

The invention belongs to the field of ecological studies and particularly relates to a plant leaf area print weighing in-vivo testing method. The method has no significant difference with an autoCAD (auto computer aided design) method in testing accuracy and can replace the autoCAD method to be used for plant leaf area testing. The technical scheme includes that the method includes the following steps: detecting and calculating paper density rho, coating markers on the whole back of a plant leaf to be tested, printing the whole shape of the leaf onto paper A to acquire a print graph of the leaf, cutting another empty paper B to make paper C in the shape of the print graph of the leaf, weighing the paper C to acquire mass m, and calculating to acquire area s of the leaf. Compared with conventional algorithms like a basic testing method or the autoCAD method, the plant leaf area print weighing in-vivo testing method has the advantages of simplicity in operation, low cost, no need to pick off the leaf, freeness of leaf damaging, conduciveness to sustainability studies and the like.

Description

technical field [0001] The invention belongs to the field of ecology research, and in particular relates to a plant leaf imprint weighing living body measurement method. Background technique [0002] As the place of photosynthesis and the medium of transpiration, plant leaves play an irreplaceable role in the process of plant growth and physiological metabolism. Therefore, the leaf area index has been used as an important trait index for investigation and research by physiology and biochemistry, cultivation, germplasm resources, crop genetics and breeding, disease control and other disciplines. Because of this, leaf surface measurement technology came into being. [0003] The development process of leaf surface measurement technology has roughly gone through two stages, namely, grid method, graph decomposition method, coefficient method and other original measurement technologies based on calculations, specifically as follows: [0004] (Liu Guanshan, Comparative Study on D...
