Description
Technical field
The present invention relates to a kind of measure herbaceous plant and nourish and generate the method for phase transpiration rate.
Background technology
Up to the present the research about plant metabolism speed Yu Individual Size relation has pertained only to breathing rate and photosynthetic rate,
Research about plant transpiration rates with Individual Size relation have not been reported.But, water is the requisite thing of vital movement
Matter, the critical assumptions of some correlation models have been directed to the principle of Water Transportation with prediction, and transpiration is plant water transport
Power, transpiration is also the important physiological activity of one of plant metabolism, transpiration rate indicate plant growth live
Power, the research to transpiration rate contributes to understanding the relation of plant metabolism speed and Individual Size comprehensively.Change in conjunction with transpiration rate
Changing, design operation is simple, result measuring method accurately, and the importance for Plant functional ecology is self-evident, and this is also
Research for the follow-up Allometric Relationships further spread out between herbaceous plant transpiration rate and Individual Size is provided convenience.
The most existing technological means is difficult to accurately measure herbal transpiration rate, and existing technological means is all by other
Index conversion obtains the transpiration rate of plant, complex operation, and precision is low.
Summary of the invention
The present invention is the method complex operation in order to solve to measure at present herbal transpiration rate, and the low technology of precision is asked
Topic, and provide a kind of and measure herbaceous plant and nourish and generate the method for phase transpiration rate.
The present invention a kind of measures the nourish and generate method of phase transpiration rate of herbaceous plant and carries out according to the following steps:
One, in flowerpot, herbaceous plant is planted, when the plant in flowerpot to florescence, by the bottom of flowerpot and sidewall
Middle and lower part preservative film compact winding seals；Height is whole height of flowerpot the 2/3 of the preservative film that flowerpot sidewall is wound around；
Two, by efficient paraffin wax heating and melting to liquid, then the coldest under the room temperature environment that temperature is 20 DEG C～35 DEG C
But 25min～30min, is coated on the soil surface in the flowerpot in step one by the efficient paraffin wax after cooling
0.1cm～0.5cm；
Three, after treating that the efficient paraffin wax in flowerpot solidifies completely, quality m of whole flowerpot is weighed with electronic scale0, so
After flowerpot be positioned at sunlight carry out photosynthesis time t, then weigh quality m of whole flowerpot with electronic scalet, then this grass
This plant transpiration rate in time t is m0-mt；Described m0Unit be g, described mtUnit be g.
What the present invention measured is herbaceous plant the nourishes and generates transpiration rate of phase.
Advantages of the present invention:
The present invention solves conventional herbaceous plant transpiration rate and is difficult to measure, by other indexes conversion inaccurate problem of gained, basis
Inventive method is easy, measure the transpiration rate of herbaceous plant every day accurately, is adapted to the transpiration rate of field high-volume different plant species
Measurement；
The big I of the measuring method institute measuring plants of the present invention regulates flowerpot size voluntarily and realizes, and certainty of measurement is also according to reality
The scale selecting different accuracy is needed to realize.
The present invention selects efficient paraffin wax, its stable in physicochemical property, energy high temperature resistant (its fusing point is 60 DEG C), Bu Huiyin
Summer, Growing season high temperature affected experiment effect, and had no side effect, and experimenter be there is no injury.
It is the damage avoiding moisture and soil that the bottom of flowerpot and the middle and lower part preservative film compact winding of sidewall are sealed by the present invention
Losing, coating efficient paraffin wax on soil is to prevent moisture evaporation and soil evaporation.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of the flowerpot in the step one of the present invention, and 1 is flowerpot, and 2 is preservative film, 2L1=L2。
Detailed description of the invention
Detailed description of the invention one: present embodiment is a kind of to measure herbaceous plant and nourish and generate the method for phase transpiration rate, specifically
Carry out according to the following steps:
One, in flowerpot, herbaceous plant is planted, when the plant in flowerpot to florescence, by the bottom of flowerpot and sidewall
Middle and lower part preservative film compact winding seals；Height is whole height of flowerpot the 2/3 of the preservative film that flowerpot sidewall is wound around；
Two, by efficient paraffin wax heating and melting to liquid, then the coldest under the room temperature environment that temperature is 20 DEG C～35 DEG C
But 25min～30min, is coated on the soil surface in the flowerpot in step one by the efficient paraffin wax after cooling
0.1cm～0.5cm；
Three, after treating that the efficient paraffin wax in flowerpot solidifies completely, quality m of whole flowerpot is weighed with electronic scale0, so
After flowerpot be positioned at sunlight carry out photosynthesis time t, then weigh quality m of whole flowerpot with electronic scalet, then this grass
This plant transpiration rate in time t is m0-mt；Described m0Unit be g, described mtUnit be g.
Detailed description of the invention two: present embodiment is unlike detailed description of the invention one: the stone of efficiently cutting into slices described in step 2
The model of wax is Q/YSQN40-91.
The effect of the employing tests below checking present invention:
Test one: this test is a kind of to measure herbaceous plant and nourish and generate the method for phase transpiration rate, enters the most according to the following steps
