Description
Technical Field
[0001] The present invention belongs to the technical field of rubber trees, and particularly relates to a leaf sample collection device and a collection method for fertilizing rubber plantations. Background Art
[0002] Fertilization is an important measure for the fast growth and high yield of rubber trees, and is also the basic work for improving the soil of rubber plantations. The technical core of soil testing and formulated fertilization is to determine the fertilization variety and quantity according to the soil test results. Therefore, how to determine the fertilizer variety and quantity is the key to the accuracy and precision of soil testing and formulated fertilization. Currently, the commonly used methods include: soil fertility zoning method, target yield method, fertilizer effect field test method, etc.
[0003] Rubber trees also have particularities in terms of cultivation and nutritional characteristics, which are mainly reflected in the following aspects: (1) The root system of rubber trees belongs to the taproot system, with a wide and deep root distribution. The main root grows vertically downward, generally deep into more than 150 cm or reaches the water surface; the lateral roots extend horizontally or obliquely, and at the same time, affected by water and fertilizer, they have a tendency to seek fertilizer; the concentrated fertilization methods such as hole fertilization and strip fertilization in rubber plantations not only make the distribution of soil nutrients extremely uneven, increasing the number of analyzed soil samples and the difficulty of sampling; on the other hand, they increase the number of lateral roots, root length, and root density on the side of the fertilization hole, changing the distribution law of the root system of rubber trees; (2) Rubber tree nutrients have storage properties, and the stored nutrients have a large buffer. After October, the climate gradually gets colder, the leaves age, and some mineral nutrients in the leaves will transfer to the main stem, root system, and branches. This part of the stored nutrients has obvious redistribution and reuse characteristics for a relatively long time, which has an important role and significance for the leaf sprouting and new shoot growth of rubber trees in the coming year; (3) Rubber trees are more sensitive to the balance ratio between nutrient elements than general field crops. For the imbalance caused by too high a certain nutrient element, in addition to stopping the application of fertilizers of this element on the one hand, fertilizers of other nutrient elements should be additionally applied to adjust the balance at the same time; and the fertilizer effect often has a lag, especially for phosphate fertilizer. The above characteristics of rubber trees bring great difficulties to the research and application of soil testing and fertilization technology. Currently, it is very difficult to directly obtain the correct fertilization amount according to the soil nutrient value through the implementation of tests such as the fertilizer effect field test method or the target yield method and the corresponding formulas.
[0004] Rubber tree nutrients have storage properties, and the stored nutrients have a large buffer. After October, the climate gradually gets colder, the leaves age, and some mineral nutrients in the leaves will transfer to the main stem, root system, and branches. This part of the stored nutrients has obvious redistribution and reuse characteristics for a relatively long time, which has an important role and significance for the leaf sprouting and new shoot growth of rubber trees in the coming year.
[0005] When analyzing nutrient distribution, leaves are usually taken for analysis. The taken leaves will first partially wither and then turn completely withered. To determine leaf withering, the observation method is usually adopted. However, visual observation can only be recorded by taking pictures or analyzed using professional instruments, which is very troublesome under the conditions of field exploration and has poor practicality. This phenomenon has become a problem that needs to be solved urgently by those in this field. Summary of the Invention
[0006] The purpose of the present invention is to provide a leaf sample collection device and a collection method for rubber plantation fertilization for the existing skidding device to solve the problems raised in the above-mentioned background technology.
[0007] To solve the above technical problems, the present invention provides the following technical solution: A leaf sample collection device and a collection method for rubber plantation fertilization, including a storage device body, characterized in that: one side of the storage device body is movably connected by a hinge with a sealing cover, and a leaf collection device is embedded inside the storage device body by an intermediate clamping method. Multiple leaves are collected through the leaf collection device, which is convenient for storage.
[0008] The present invention further explains that the leaf collection device includes a fixed-mounted square plate and a rotatably-mounted square plate. A partition shaft is connected by a hinge between the fixed-mounted square plate and the rotatably-mounted square plate. One side of the fixed-mounted square plate and the rotatably-mounted square plate is embedded with an extrusion deformation sinking body by a movable insertion and intermediate clamping method. By squeezing the leaf to the extrusion deformation sinking body, the position of the extrusion deformation sinking body is changed to different degrees, which is convenient for recording.
[0009] The present invention further explains that round head limit blocks are uniformly fixed on one side of the fixed-mounted square plate and the rotatably-mounted square plate by contact welding. One end of the round head limit block is fixed with an inner rod by contact welding. An outer sleeve rod is sleeved on the outside of the inner rod in an annular outer contour manner. The extrusion deformation sinking body slides and is sleeved on the outer sleeve rod in an annular outer contour manner. Due to the movement of the extrusion deformation sinking body, the withered part of the leaf is thinner and will not press the extrusion deformation sinking body down too much distance, otherwise it will press down a larger distance.
[0010] The present invention further explains that resistance conductive strips are fixed on both sides of the outer sleeve rod by contact welding. A moving conductive block is embedded inside the outer sleeve rod by a sliding and intermediate clamping method. The moving conductive block is adhesively fixed to the extrusion deformation sinking body. The moving conductive block is electrically connected to the resistance conductive strip. Since the position of the moving conductive block is different, the resistance accessed during power-on is also different, so that the change in current can be sensed to indirectly display the position of the extrusion deformation sinking body, and thus react to whether the leaf at the current position is withered.
[0011] The present invention further illustrates that a spring is embedded between the round head limit block and the extrusion deformation sinking body in an intermediate clamping manner, and a fixing block is fixedly installed on the inner wall of the storage device body by means of bolt connection. The bottom of the fixing block is embedded with a leaf pressure deformation flattening plate in a manner of movable insertion and intermediate clamping.
[0012] The present invention further illustrates that a guiding track is annularly formed inside the storage device body, and a circular slider is sleeved on the guiding track in a manner of sliding with an annular outer contour. The circular slider is fixed to the fixedly installed square plate by contact welding. Through the elastic deformation of the spring, it can quickly return to its original state after the leaf is taken out, facilitating multiple uses without manual reset. The leaf pressure deformation flattening plate can better flatten the leaf.
[0013] The present invention further illustrates that the usage method of the device is as follows:
[0014] S1. Collect the leaves from the oak tree and place them flat above the fixedly installed square plate and the rotatably installed square plate.
[0015] S2. Use the leaf pressure deformation flattening plate to flatten the leaves so that both the withered part and the non-withered part are closely attached to the extrusion deformation sinking body.
[0016] S3. Study the withering degree and withering distribution state of the leaves, collect multiple leaves simultaneously, and put them into the leaf collection device.
[0017] S4. When collecting the next leaf, slide the slider on the guiding track and fold it when it contacts the fixedly installed square plate below to pass through smoothly. By folding, it does not occupy space and is convenient for storing more leaves.
[0018] The present invention further illustrates that in the above step S3, the specific method for studying the withering distribution state is that when the leaf pressure deformation flattening plate presses down, the withered part will not move the moving conductive block downward compared with the healthy part, while the healthy part, due to its thicker thickness, will move the moving conductive block downward by a certain distance, making the resistance at the current position of the extrusion deformation sinking body smaller. Record the withering distribution of the leaves according to the current size changes at each position, and record the withering distribution of the leaves according to the current size changes at each position, so as to accurately quantify and analyze the withering degree of the leaves.
[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention flattens the leaves by using a movable embedded block, and at the same time studies the withering distribution degree of the leaves, which has a higher accuracy than the naked-eye observation method and is convenient for recording.

Detailed Embodiment
[0027] The following is a non-limiting detailed description of the technical solution of the present invention in combination with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: a blade sample collection device and collection method for rubber garden fertilization, including a storage device main body 1, characterized in that: one side of the storage device main body 1 is movably connected by a hinge with a sealing cover 2, and the inside of the storage device main body 1 is embedded with a blade collection device 3 in an intermediate clamping manner, and multiple blades are collected through the blade collection device 3 for convenient storage;
[0029] The blade collection device 3 includes a fixed-mounted square plate 31 and a rotatably-mounted square plate 33. A partition shaft 32 is connected between the fixed-mounted square plate 31 and the rotatably-mounted square plate 33 by a hinge. On one side of the fixed-mounted square plate 31 and the rotatably-mounted square plate 33, an extrusion-deformation sinking body 34 is embedded in a manner of movable insertion and intermediate clamping. By squeezing the extrusion-deformation sinking body 34 with the blade, the position of the extrusion-deformation sinking body 3 is changed to different degrees, which is convenient for recording;
[0030] On one side of the fixed-mounted square plate 31 and the rotatably-mounted square plate 33, round head limit blocks 345 are uniformly fixed by contact welding. One end of the round head limit block 345 is fixed with an inner rod by contact welding. An outer sleeve rod 343 is sleeved on the outside of the inner rod in an annular outer contour manner. The extrusion-deformation sinking body 34 slides and is sleeved on the outer sleeve rod 343 in an annular outer contour manner. Due to the movement of the extrusion-deformation sinking body 34, the withered part of the blade is relatively thin and will not press the extrusion-deformation sinking body 34 down too much distance. On the contrary, it will press a larger distance;
[0031] On both sides of the outer sleeve rod 343, resistance conductive strips 344 are fixed by contact welding. A moving conductive block 341 is embedded in the outside of the outer sleeve rod 343 by intermediate clamping. The moving conductive block 341 is adhesively fixed to the extrusion-deformation sinking body 34. The moving conductive block 341 is electrically connected to the resistance conductive strip 344. By connecting an external power supply to the outside of the resistance conductive strip 344, due to the different positions of the moving conductive block 341, the resistance connected when energized is also different. Thus, the change in current can be sensed to indirectly display the position of the extrusion-deformation sinking body 34, and thus react to whether the blade at the current position is withered;
[0032] A spring 342 is embedded between the round head limit block 345 and the extrusion-deformation sinking body 34 by intermediate clamping. The inner wall of the storage device body 1 is fixedly installed with a fixed block 5 by bolt connection. A leaf pressure-deformation flattening plate 51 is embedded at the bottom of the fixed block 5 by movable insertion and intermediate clamping. Through the elastic deformation of the spring 342, it can quickly return to its original state after the blade is taken out, which is convenient for multiple uses without manual reset. The leaf pressure-deformation flattening plate 51 can better flatten the blade;
[0033] A guide track 4 is annularly opened inside the storage device body 1. A circular slider 35 is slidably sleeved on the guide track 4 in an annular outer contour manner. The circular slider 35 is fixed to the fixed-mounted square plate 31 by contact welding. After one blade is collected, more blades can be collected in the same way. By sliding the circular slider 35 on the guide track 4, the position of the previously stored blade can be changed, which is convenient for collecting the next blade;
[0034] The usage method of this device is as follows:
[0035] S1. Collect the leaves from the oak tree and place them flat above the fixedly installed square plate 31 and the rotatably installed square plate 33;
[0036] S2. Use the leaf pressure deformation flattening plate 51 to flatten the leaves so that both the withered part and the non-withered part are closely attached to the extrusion deformation sinking body 34;
[0037] S3. Study the withering degree and withering distribution state of the leaves, collect multiple leaves simultaneously, and put them into the leaf collection device 3;
[0038] S4. When collecting the next leaf, slide the slider 35 on the guiding track 4, and fold it when it contacts the lower fixedly installed square plate 31 to pass through smoothly. The folding method does not occupy space and is convenient for storing more leaves;
[0039] In the above step S3, the specific method for studying the withering distribution state is that when the leaf pressure deformation flattening plate 51 presses down, the withered part will not move the movable conductive block 341 downward compared with the healthy part, while the healthy part, due to its thicker thickness, will move the movable conductive block 341 downward by a certain distance, making the resistance at the current position of the extrusion deformation sinking body 34 smaller. Record the withering distribution of the leaves according to the current size changes at each position, so as to accurately quantify and analyze the withering degree of the leaves.

[0041] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
