Description

Technical Field

[0001] The invention relates to the technical field of litter decomposition, and in particular to a terrestrial ecosystem litter decomposition observation device. Background Art

[0002] Litter decomposition is the main way of nutrient return in forest ecosystems. When litter falls on the surface of the forest, biological, physical and chemical decomposition processes begin, including the leaching of water-soluble compounds, the fragmentation of litter by soil animals, the material conversion by microorganisms, and the transformation of organic matter and mineral compounds into soil. Litter is a product of plant metabolism during growth and development, and has important ecological significance for nutrient cycling and soil and water conservation in terrestrial ecosystems. Woody plant litter is a key factor affecting grassland plant renewal. Nutrient elements are released during litter decomposition, and nutrients are returned to the soil, thereby improving soil structure, enhancing soil water and fertilizer retention capacity, increasing soil microbial activity and species diversity, and providing fertilizers needed for plant growth and development. The type, quality, decomposition rate, and nutrient status of litter determine the nutrient cycle process of the ecosystem, change the growth environment of plants, and thus affect the shrub-grass coupling process and the yield and quality of plants. It can be seen that litter is an important nutrient transport channel between vegetation and soil, and is also a key link affecting carbon cycle. It plays an irreplaceable role in regulating the material cycle and energy flow of terrestrial ecosystems. Therefore, it is necessary to study the impact of litter on the structural stability and ecological function of ecosystems.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, when it is necessary to reduce the observation period, the terrestrial ecosystem litter decomposition observation device is pre-installed at the observation site through multiple insertion rods, and the multiple insertion rods are inserted into the soil, so that the terrestrial ecosystem litter decomposition observation device is fixed at the litter observation site, and then the first motor is operated by the control terminal, and the operation of the first motor drives the worm to rotate, and the rotation of the worm and the mutual meshing of the two worm wheels make the two worm wheels rotate relative to each other, and the relative rotation of the two worm wheels drives the two rotating shafts to rotate relative to each other, and the relative rotation of the two rotating shafts drives the two rollers to rotate relative to each other, and the relative rotation of the two rollers drives the multiple crushing knives on the surface of the two rollers to rotate relative to each other, and the multiple crushing knives on the surface of the two rollers The relative rotation achieves a crushing effect, and the litter is added into the box body to be crushed. The crushed litter is discharged from the bottom of the box body, and the crushed litter falls on the surface of the triangular plate. The triangular plate makes the crushed litter scattered more evenly on the surface of the litter decomposition site, so that the crushed litter is scattered more evenly on the surface of the soil. Through the cooperation of the above structure, multiple crushing knives can crush the litter, and at the same time make the crushed litter scattered more evenly on the surface of the soil, so that soil animals and litter are fully in contact, the decomposition of the litter is accelerated, and the decomposition cycle of the litter is greatly reduced.

[0015] 2. When the terrestrial ecosystem litter decomposition observation device of the present invention is used, it is fixed in the soil by multiple insertion rods. When it is necessary to observe the decomposition of litter, the disc is first pulled to move the disc upward. The upward movement of the disc will stretch the spring, so that the spring is stretched. At the same time, the upward movement of the disc drives the limit rod to move. The movement of the limit rod causes itself to move out of the inside of the limit hole. The limit rod moves out of the inside of the limit hole, so that the guardrail door loses its limit. At this time, the guardrail door is pulled to rotate with the rotating rod as the central axis. When the guardrail door rests on one side surface of the box body, the litter inside can be observed. When the observation is completed, the disc is pulled again and Push the guardrail door in the opposite direction. When the guardrail door is reset, just release the disc and use the resilience of the spring to reinsert the limit rod into the limit hole. The limit rod is inserted into the limit hole to limit the rotation of the guardrail door, thereby protecting the litter decomposition site to prevent large animals from disturbing the litter decomposition site. At the same time, the monitoring probe is connected to the external display device, and the image can be transmitted to the display device in real time for display, which is convenient for observing the decomposition progress of the litter. Through the cooperation of the above structure, the three guardrails and the guardrail door enclose the litter decomposition site to prevent large animals from disturbing the litter decomposition site. At the same time, the guardrail door can be opened quickly to facilitate the observation of the decomposition of the litter.

[0016] 3. In the present invention, when it is necessary to further prevent large animals from approaching, firstly, two second motors and multiple speakers are operated through the control terminal, and the multiple speakers are operated to emit driving sounds. At the same time, the two second motors drive the two turntables to rotate, and the rotation of the two turntables drives the multiple extension rods to rotate with the center of the two turntables as the center axis. Short ribbons are tied to the surfaces of the multiple extension rods, thereby driving the multiple short ribbons to rotate. The rotation of the short ribbons cooperates with the multiple speakers to emit sounds to drive away the animals. Through the cooperation of the above structure, the multiple broken ribbons rotate and cooperate with the multiple speakers to emit sounds to drive away the animals, thereby preventing animals from destroying the litter decomposition observation site and affecting the observation results of litter decomposition.

[0042] In one embodiment, the two driving components 9 include multiple L-shaped plates 901, which are fixedly mounted on one side surface of multiple pillars 5, and speakers 902 are fixedly mounted on one side surface of the multiple L-shaped plates 901. The multiple L-shaped plates 901 are grouped in pairs, and a circular plate 903 is fixedly mounted between each group of L-shaped plates 901.

[0046] Working principle: When the terrestrial ecosystem litter decomposition observation device is in use, it is fixed in the soil by inserting a plurality of insertion rods 6. When the observation period needs to be reduced, the terrestrial ecosystem litter decomposition observation device is inserted in the observation location in advance by means of a plurality of insertion rods 6. The plurality of insertion rods 6 are inserted into the soil, thereby fixing the terrestrial ecosystem litter decomposition observation device at the litter observation location. Subsequently, the first motor 307 is operated through the control terminal 2. The operation of the first motor 307 drives the worm 306 to rotate. The rotation of the worm 306 and the mutual meshing of the two worm wheels 304 make the two worm wheels 304 rotate relative to each other. The relative rotation of the two worm wheels 304 drives the two rotating shafts 301 to rotate relative to each other. The relative rotation of the two rotating shafts 301 drives the two rollers 302 to rotate relative to each other. The relative rotation of the two rollers 302 drives the The multiple crushing knives 303 on the surface of the two rollers 302 rotate relatively, and the multiple crushing knives 303 on the surface of the two rollers 302 rotate relatively to achieve a crushing effect. At this time, litter is added into the box body 1 to crush the litter. The crushed litter is discharged from the bottom of the box body 1, and the crushed litter falls on the surface of the triangular plate 308. The triangular plate 308 makes the crushed litter more evenly scattered on the surface of the litter decomposition site, so that the crushed litter is more evenly scattered on the surface of the soil. Through the cooperation of the above structure, the multiple crushing knives 303 can crush the litter, and at the same time make the crushed litter more evenly scattered on the surface of the soil, so that the soil animals and the litter are fully in contact, the decomposition of the litter is accelerated, and the decomposition cycle of the litter is greatly reduced;When it is necessary to observe the decomposition of fallen leaves, the disc 806 is first pulled to move the disc 806 upward. The upward movement of the disc 806 stretches the spring 807, thereby stretching the spring 807. At the same time, the upward movement of the disc 806 drives the limit rod 805 to move. The limit rod 805 moves to move itself out of the limit hole 809. The limit rod 805 moves out of the limit hole 809, thereby causing the guardrail door 802 to lose its limit. At this time, the guardrail door 802 is pulled to rotate around the rotating rod 801 as the central axis. When the guardrail door 80 2 is placed on one side of the box 1, and the litter inside can be observed. When the observation is completed, the disc 806 is pulled again and the guardrail door 802 is pushed in the opposite direction. When the guardrail door 802 is reset, the disc 806 can be released, and the limit rod 805 is inserted into the limit hole 809 again by the rebound force of the spring 807. The limit rod 805 is inserted into the limit hole 809, thereby limiting the rotation of the guardrail door 802, thereby protecting the litter decomposition site and preventing large animals from disturbing the litter decomposition site. At the same time, the monitoring probe 810 By docking with an external display device, the image can be transmitted to the display device in real time for display, which is convenient for observing the decomposition progress of the litter. Through the cooperation of the above structure, the three guardrails 7 and the guardrail door 802 enclose the litter decomposition site to prevent large animals from disturbing the litter decomposition site. At the same time, the guardrail door 802 can be opened quickly to facilitate the observation of the decomposition of the litter. When it is necessary to further prevent large animals from approaching, firstly, the two second motors 904 and the multiple speakers 902 are operated through the control terminal 2, and the multiple speakers 902 are operated to emit a driving sound, and at the same time When the two second motors 904 are running, the two turntables 905 are driven to rotate. The rotation of the two turntables 905 drives the multiple extension rods 906 to rotate with the center of the two turntables 905 as the central axis. Short ribbons are tied to the surfaces of the multiple extension rods 906, thereby driving the multiple short ribbons to rotate. The rotation of the short ribbons cooperates with the multiple speakers 902 to make sounds to drive away animals. Through the cooperation of the above structure, the rotation of the multiple broken ribbons cooperates with the multiple speakers 902 to make sounds to drive away animals, thereby preventing animals from destroying the litter decomposition observation site and affecting the observation results of litter decomposition. ;
