Embodiment 1

[0133] Example 1 Comparison of low nutrient tolerance and nutrient use efficiency of mulberry trees grown under two kinds of habitats (better habitat and moderate rocky desertification environment) (note: G-1-1, G-1-2 represent growth In the two mulberry plants with better habitat, G-2-1, G-2-2, and G-2-3 represent the three mulberry plants growing in the rocky desertification environment)

[0134] In the base of the Puding Karst Ecological Comprehensive Experimental Station in Guizhou Province, Chinese Academy of Sciences, fresh branches of mulberry trees were picked under two kinds of habitats (better habitat and moderate rocky desertification environment), and they were quickly returned to the laboratory to clean the leaves on the fresh branches. After removing the dust on the surface, collect the second unfolded leaves from the fresh branches one by one as the leaves to be tested, and soak them in distilled water for 30 minutes; blot the surface water of the leaves, and imm...

Embodiment 2

[0155] Capsicum and potato under the same habitat of embodiment 2 low nutrient tolerance and nutrient utilization efficiency comparison (P-1, P-2, P-3 represent three plants of capsicum, kind: 8226, T-1, T-2 are representative Two plants of potatoes, variety: Fewuruita) picked pepper and potato branches at the experimental field of Qingzhen Agricultural Vocational College, Guiyang, and returned to the laboratory quickly. Collect the second unfolded leaf as the leaf to be tested, put it in distilled water and soak for 30 minutes; blot the water on the surface of the leaf, and immediately clamp the leaf to be tested between the parallel electrode plates of the measuring device, set the measuring voltage and frequency, and change the iron block The quality is used to set different clamping forces, and the parallel mode is used to measure the physiological capacitance, physiological resistance, and physiological impedance of plant leaves under different clamping forces; the physiol...

Abstract

The invention discloses a method for quantifying low-nutrition tolerance and nutrient utilization efficiency of plants, belonging to the technical field of agricultural engineering and crop information detection, measuring the physiological resistance, physiological impedance and physiological capacitance of plant leaves under different clamping forces, and further calculating the plant leaf Physiological capacitive reactance and physiological inductive reactance; according to the Nernst equation, the physiological resistance of plant leaves changes with the clamping force, the physiological capacitive reactance of plant leaves changes with the clamping force, and the physiological inductive reactance of plant leaves changes with the clamping force. The parameters of the above three models are used to calculate the intrinsic physiological resistance, intrinsic physiological capacitive reactance and intrinsic physiological inductive reactance of plant leaves, and further obtain the active and passive transfer capacity of plant leaves based on electrophysiological parameters, and finally quantify the plant's tolerance to low nutrition. capacity and nutrient utilization efficiency. The present invention can not only quickly and online quantitatively detect the low nutrient tolerance and nutrient utilization efficiency of different plants in different environments, and the measured results are comparable, but also can use biophysical indicators to characterize the nutrient requirements of different plants in different environments, and provide a basis for crops. Fertilization provides scientific data.
