Description

Technical Field

[0001] The present invention relates to the field of drought resistance testing, and more specifically, to a device and method for testing drought resistance of ground cover plants. Background Art

[0002] Ground cover plants refer to plants with dense, low clusters that can be used to replace lawns to cover the ground surface, prevent soil erosion, absorb dust, purify the air, reduce noise, eliminate pollution, and have certain ornamental and economic value after simple management. Water conditions are an important factor in the growth and development of ground cover plants. Water shortages can cause a series of effects such as water loss in ground cover plant cells, decreased turgor pressure, endogenous hormone disorders, and reduced antioxidant capacity. Therefore, studying the drought resistance of ground cover plants is currently a hot topic in ground cover plant research. However, the drought resistance of ground cover plants cannot be evaluated by a single indicator. Therefore, in the prior art, the drought resistance of ground cover plants is often evaluated by using the potting method, in which a variety of ground cover plants to be tested are placed in pots, and watering is stopped after the initial normal watering. Then, the appearance of the ground cover plants is regularly observed, and various physiological and biochemical indicators are detected. Finally, the drought resistance of multiple ground cover plants can be obtained by processing them using methods such as principal component analysis or fuzzy mathematical membership function, and important indicators of drought resistance can be preliminarily screened out, such as the journal article "Evaluation of Drought Resistance and Screening of Drought Resistance Indicators of Five Garden Ground Cover Plants in Taiyuan City" published by Bo Wei, the journal article "Physiological Responses of Three Ground Cover Plants under Drought Stress and Evaluation of Drought Resistance" published by Sun Ying, Chen Jianan's master's thesis "Evaluation of Drought Resistance and Salt Tolerance of Road Ground Cover Plants in Beijing", and Liu Ayun's master's thesis "Comprehensive Evaluation of Drought Resistance of Seven Lawn Ground Cover Plants".

[0047] In another technical solution, it also includes:

[0048] A horizontal test tank 1, with its notch facing upward, and one end of the test tank 1 being open;

[0049] A plurality of water spraying mechanisms are arranged on the bottom of the test tank 1, and the plurality of water spraying mechanisms correspond to the plurality of test mechanisms one by one. Each water spraying mechanism includes a pair of supporting shells 3, and the pair of supporting shells 3 corresponds to a pair of planting tanks 901.

At this time, the soil in the planting trough 901 is poured into the collecting trough 2, and then the collecting trough 2 is taken out of the test trough 1, and the driving telescopic rod 7 is started again, causing the planting trough assembly 9 to descend to the planting trough 901 and buckled on the supporting shell 3. At this time, the middle part of the planting trough 901 is in contact with the supporting shell 3, and then the nozzle 4 sprays Water is used to wash the residual soil on the inner wall of the planting trough 901. The planting trough 901 is covered on the supporting shell 3 to prevent water from splashing everywhere. At the same time, the water sprayed by the nozzle 4 cleans the inner wall of the planting trough 901 and flows out from the notch of the planting trough 901 that is not in contact with the supporting shell 3.

Finally, the driving telescopic rod 7 is started to lower the planting trough assembly 9 until the planting trough assembly 9 contacts the inner bottom wall of the collecting trough 2. At this time, the cylindrical sheet 13 is attached to the inner wall of the planting trough 901 to carry out the next test;

[0068] In the above technical solution, the drought resistance test device for ground cover plants is used to conduct a drought resistance test for ground cover plants. After the test is completed, it is convenient to dump the soil and clean the planting trough, saving time and effort.

[0069] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the ground cover plant drought tolerance test device of the present invention will be obvious to those skilled in the art.

[0070] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
