Description
MONITORING DEVICE AND SOIL IMPROVEMENT METHOD FOR TEA PLANT IN TEA
GARDENS
The invention relates to the technical field of tea cultivation, and in particular to a monitoring device and a soil improvement method for tea plant in tea gardens.
Tea plant is an acid-loving crop, and acid soil is one of the necessary ecological conditions for tea plant growth. But it's not that the more sour the soil, the better the growth of tea trees.
Results show that the soil pH value of 4.5 - 6.5 is most suitable for the growth of tea plants, and the pH value of 4.5 - 5.5 is the most suitable value. When the pH value is higher than 6.5, the growth of tea plant gradually stagnates, and the tea plant even dies when the pH value exceeds 7.0; when the pH value is lower than 4.0, the growth of tea plants is inhibited, and tea products and quality will be affected.
Under natural conditions, due to physiological functions of tea plants, after tea plants are planted, under the action of organic acids secreted by tea root system, soil in tea gardens is gradually acidified, and the acidification rate is 0.071 per year. As a cash crop for harvesting leaf organs, tea often needs to be applied nitrogen fertilizer (especially NH**) to ensure sufficient yield.
Therefore, due to the use of nitrogen fertilizer and the nitrification of NH**, the acidification of tea garden will be intensified. In addition, after tea leaves are picked, tea products take away alkali metals and alkaline-earth metals such as K, Ca and Mg in the soil, and this has a positive effect on H* accumulation, while the absorption of P and S in tea plant has a negative effect on H* accumulation. Under a comprehensive action, the net accumulation of H* in tea garden soil is positive, and soil acidification is intensified. This acidification aggravates the soluble content of heavy metals in tea garden soil, and then increases the possibility of enriching heavy metals in tea, thus increasing the health risk of people. Results show that the acidification of tea garden soil not only occurs in the surface soil, but also extends to the depth of 2.0 m below the surface. With the age of tea trees and the application of nitrogen fertilizer increasing, risks of nutrient elements
N and P getting wet will also increase, and acid will move downwards. Long-term application of nitrogen fertilizer promotes accumulation of exchangeable A[?*, and the hydrolysis of AI** further produces H*, thus accelerating the acidification of tea garden soil. In the prior art, there is no device for monitoring the contents of organic acids and alkali metal ions in tea garden soil, nor for quantitatively applying fertilizer to tea garden. Therefore, there is an urgent need for a monitoring device for tea plants in tea garden and a soil improvement method to solve the problem.

The first rotating shaft 14 drives the one-way rotating part to rotate, and the rotating plate 21 opens under the action of the one-way rotating part, so that the fertilizer drops from the blending box 25 to the soil at the root of the tea plant. The blending box 25 is used for mixing two kinds of fertilizers evenly, and the quantitative discharging part is used for applying quantitative fertilizers to the roots of tea plants.
Further optimization scheme, the one-way rotating part includes a fixed runner 18 fixedly connected with the first rotating shaft 14, the outer wall of the fixed wheel 18 is sleeved with a first runner 17, the outer wall of the first runner 17 is fixedly connected with a plurality of shifting teeth, the shifting teeth are in contact with the bottom surface of the rotating plate 21, the side wall of the fixed runner 18 is rotatably connected with a pawl 19, one side wall of the pawl 19 is in contact with the fixed runner 18, the other side wall of the pawl 19 is connected with one end of a second spring 20, and the other end of the second spring 20 is fixedly connected with the fixed runner 18; the inner wall of the first wheel 17 is fixedly connected with a plurality of ratchet teeth, and the ratchet teeth are arranged corresponding to the pawls 19.
When the pressing plate 10 moves downward, the first rotating shaft 14 rotates clockwise, and the first rotating shaft 14 drives the fixed runner 18 to rotate. During the clockwise rotation of the fixed runner 18, the side wall of the pawl 19 contacts with the fixed runner 18 and keeps itself relatively stationary with the fixed runner 18; the pawl 19 contacts against the ratchet teeth on the inner wall of the first runner 17, thus driving the first runner 17 to rotate clockwise. When the first runner 17 rotates clockwise, the rotating plate 21 is rotated by the shifting teeth on the outer wall of the first runner 17, and the rotating plate 21 intermittently rotates for a certain angle and resets, so that a gap is generated between the rotating plate 21 and the bottom of the blending box 25, and the fertilizer leaks out; on the contrary, when the pressing plate 10 moves upward, the first rotating shaft 14 rotates anticlockwise, and the pawl 19 swings to the right, pressing the second spring 20; after the pawl 19 contacts with the ratchet teeth, it will not remain stationary, but will repeatedly rebound under the elastic force of the second spring 20, and cannot drive the first runner 17 to rotate. Therefore, only when the pressing plate 10 moves downward, the fertilizer will fall from the blending box 25.
Further optimization scheme, the middle of the rotating plate 21 is rotatably connected with one end of the second rotating shaft 22, the other end of the second rotating shaft 22 is fixedly connected with the frame 33, the side wall of the blending box 25 is fixedly connected with a fixed plate 24, and the fixed plate 24 is located above the rotating plate 21, and the bottom surface of one end of the fixed plate 24 close to the first runner 17 is fixedly connected with one end of a third spring 23, and the other end of the third spring 23 is fixedly connected with the rotating plate 21. The rotating plate 21 rotates anticlockwise around the second rotating shaft 22. Because one side of the rotating plate 21 is tightly attached to the blending box 25, if the rotating plate 21 rotates clockwise, it will get stuck. When the shifting teeth shift one end of the rotating plate 21 upwards, the middle part of the rotating plate 21 is rotatably connected with the second rotating shaft 22, and the end of the rotating plate 21 close to the blending box 25 moves away from the blending box 25, so that the fertilizer in the blending box 25 drops to the soil near the roots of tea plants.
Further optimization scheme, the inner wall of the blending box 25 is fixedly connected with a plurality of first inclined plates 28, and the first inclined plates 26 are vertically arranged along the inner wall of the blending box 25; the side wall of the blending box 25 opposite to the first inclined plate 26 is fixedly connected with a plurality of second inclined plates 27, and the second inclined plates 27 are vertically arranged along the inner wall of the blending box 25. Both the first inclined plates 26 and the second inclined plates 27 are inclined to the bottom surface of the blending box 25, and the first inclined plates 26 and the second inclined plates 27 are staggered.
Different fertilizers fall on the first inclined plate 26 and the second inclined plate 27, and they are mixed alternately. A plurality of first inclined plates 26 and the second inclined plates 27 are vertically arranged, so that the blending time is long and the blending uniformity is high.
Further optimization scheme, the quantitative discharging part includes a discharging shell 30, and the discharging shell 30 is fixedly connected with the frame 33; one end of the discharging shell 30 is located above the blending box 25, the inside of discharging shell 30 is rotatably connected with the screw 29, the other end of the discharging shell 30 is fixedly connected with the motor 28, and the output shaft of the motor 28 is fixedly connected with the end of the screw 29; the feeding funnel 31 is fixedly connected above the discharging shell 30, and the feeding funnel 31 is communicated with the discharging shell 30. The feeding funnel 31 is filled with fertilizer. The motor 28 is a stepping motor, and the rotation angle is accurately controlled. The rotation of the motor 28 drives the screw 29 to rotate, and the screw 29 pushes out the fertilizer and drops it into the feeding funnel 31.
A soil improvement method based on the monitoring device for tea plants in tea gardens, which includes the following steps: dividing different acidified tea gardens into different experimental areas, selecting several tea plants as experimental objects in each experimental area, and inserting the monitoring device for tea plant in the tea garden near each tea plant;
several monitoring devices of tea gardens in the same experimental area applying different proportions of fertilizers to the soil, and observing the changes of element content in the soil near the roots of tea trees before and after fertilization, so as to determine the best fertilizer proportion to reduce the acidity of tea garden soil.
Inserting the monitoring component and the bottom of the frame 33 into the soil of the tea plant root, and adding different fertilizers into the two feeding funnels 31 respectively; inserting the tip of the spring sleeve 1 into soil until the top of the second sliding sleeve 4 is flush with the soil surface; according to experimental requirements, respectively adding different fertilizers into the two feeding funnels 31 of the same tea garden monitoring device of the present application, the rotation angles of the motor 28 corresponding to the quality of the added fertilizers one by one, and the two motors 28 rotating at a specific angle, so that fertilizers with different contents are added into the blending box 25.
After the pressure plate 10 is pressed, the sliding column 5 drives the first focusing lens 8 and the second focusing lens 9 to slide towards underground to measure the element content in the soil before fertilization; the laser emitted by the laser transmitter (not shown in the figures) is transmitted to the first focusing lens 8 through the incident optical fibre 11. After the laser irradiates the soil, the soil generates plasma, and the spectrum excited by the plasma is collected by the second focusing lens 8 and transmitted back to the control part through the acquisition optical fibre 12. The incident optical fibre 11 and the acquisition optical fibre 12 are both arranged inside the sliding column 5. When the sliding column 5 moves from top to bottom, the laser will continuously irradiate the soil at different depths, so as to obtain the content of elements in the soil at different depths. By rotating the pressing plate 10 for a certain angle and repeatedly pressing the pressing plate 10, the content of soil elements near the vertical area of the last soil measurement can be measured. By repeatedly rotating the pressing plate 10 for several times, the content of soil elements can be measured, and the measured results are averaged, so that the measured results are more objective and comprehensive.
While the pressing plate 10 moves downwards, different fertilizers with a certain proportion are scattered in the soil near the roots of tea plants; when the pressing plate 10 moves downwards, it drives the clamping seat 13 to move downwards, and the clamping seat 13 drives the rack 16 to move downwards. The rack 16 meshes with the gear 15 in the middle of the first rotating shaft 14, and the gear 15 and the first rotating shaft 14 rotate together relative to the side wall of the frame 33. The first rotating shaft 14 drives the fixed runner 18 to rotate. During the clockwise rotation of the fixed runner 18, the side wall of the pawl 19 contacts with the fixed runner 18 and keeps itself relatively stationary with fixed runner 18. The pawl 19 contacts against the ratchet teeth on the inner wall of the first runner 17, thus driving the first runner 17 to rotate clockwise. When the first runner 17 rotates clockwise, the shifting teeth on the outer wall of the first runner 17 shift the rotating plate 21 to rotate. When the shifting teeth shift one end of the rotating plate 21 upwards, the middle part of the rotating plate 21 is rotatably connected with the second rotating shaft 22, and the end of the rotating plate 21 close to the blending box 25 moves away from the blending box 25, so that the fertilizer in the blending box 25 drops. After a period of time, the pressure plate 10 is pressed again, and the content of elements in the soil after fertilization is measured and compared with that before fertilization.
Organic fertilizer and nitrogen fertilizer are added into the two feeding funnels 31 respectively. Organic fertilizer includes commercial organic fertilizer, bio-organic fertilizer, carbon- based fertilizer, biochar, etc. Typical acidified tea gardens (pH 4.5-6.5) and (pH 4.0 < pH < 4.5)) are selected for soil improvement and remediation experiments, and the acidity of tea garden soil after the soil is applied different biomass materials is determined to find out the best biomass materials and its ratio.
