specific Embodiment approach 1

[0015] Embodiment 1: This embodiment is a method for measuring transpiration during the vegetative propagation period of herbaceous plants, specifically according to the following steps:

[0016] 1. Plant herbal plants in flowerpots. When the plants in the flowerpots reach the flowering stage, tightly wrap the bottom of the flowerpot and the middle and lower parts of the side walls with plastic wrap; the height of the plastic wrap wrapped around the side walls of the flowerpot is 2 / 3 of the height of the entire pot;

[0017] 2. Heat and melt the high-efficiency sliced ​​paraffin to a liquid state, then cool it naturally at room temperature at 20°C to 35°C for 25min to 30min, and apply the cooled high-efficiency sliced ​​paraffin on the soil surface in the flowerpot in step 1 0.1cm~0.5cm;

[0018] 3. After the high-efficiency sliced ​​paraffin in the flowerpot is completely solidified, use an electronic scale to weigh the mass of the entire flowerpot m 0 , and then place the ...

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment differs from Embodiment 1 in that: the model of the high-efficiency section paraffin described in step 2 is Q / YSQN40-91.

[0020] Adopt following test to verify effect of the present invention:

[0021] Test 1: This test is a method for measuring the transpiration of herbaceous plants during the vegetative propagation period, specifically carried out according to the following steps:

[0022] 1. Plant quinoa cuspidatum in a flowerpot. When the quinoa cuspidatum in the flowerpot reaches the flowering period, wrap the bottom of the flowerpot and the middle and lower part of the side wall tightly with plastic wrap; The height of the plastic wrap is 2 / 3 of the height of the entire flowerpot;

[0023] 2. Heat and melt the high-efficiency sliced ​​paraffin to a liquid state, and then cool it naturally for 25 minutes at a room temperature of 30°C, and apply the cooled high-efficiency sliced ​​paraffin to 0.3cm of the soil surface in the flowerpot...

Abstract

The invention relates to a method for measuring the transpiration volume of herbaceous plants in a vegetative propagation stage. The technical problems of tedious operation and low precision of present methods for measuring the transpiration rate of herbaceous plants are solved. The method comprises the following steps: 1, sealing the bottom of a flowerpot and the middle and lower portion of the sidewall of the flowerpot; 2, sealing soil surface; and 3, weighing the mass before and after photosynthesis, and calculating a mass difference. The method has the following advantages: the previous problems of difficult measurement of the transpiration volume of herbaceous plants and inaccuracy of the result obtained through converting other indexes are solved; the method allows the daily transpiration volume of herbaceous plants to be simply and accurately measured, and adapts to measurement of the transpiration volume of large-batch field different species; and the size of the flowerpot can be adjusted to adapt the size of the measured plants through the measurement method, and the measurement precision is realized through selecting scales with different precisions according to practical needs. The method is used to measure the transpiration volume of herbaceous plants in the vegetative propagation stage.

Description

technical field [0001] The invention relates to a method for measuring transpiration in the vegetative propagation period of herbaceous plants. Background technique [0002] So far, the research on the relationship between plant metabolic rate and individual size only involves respiration rate and photosynthetic rate, and there is no report on the relationship between plant transpiration rate and individual size. However, water is an essential substance for life activities. The key assumptions and predictions of some related models involve the principle of water transport. Transpiration is the driving force of plant water transport, and transpiration is also an important physiological activity of plant metabolism. Transpiration The rate indicates the growth vigor of the plant, and the study of the transpiration rate helps to fully understand the relationship between plant metabolic rate and individual size. Combining with the change of transpiration, designing a measurement...
