Description

Technical Field

[0001] The present invention relates to the technical field of soil monitoring, and particularly relates to a soil fertility detection device for plum planting. Background Art

[0002] Soil fertility detection is a key link in the scientific planting of plums. By detecting the contents of nitrogen, phosphorus, potassium and trace elements in the soil, the waste or nutritional imbalance caused by blind fertilization can be avoided. For example, during the flowering period of plum trees, phosphorus and potassium fertilizers are needed to promote flower bud differentiation, while excessive nitrogen fertilizer is likely to cause excessive growth of branches and leaves. The detection data can provide an accurate basis for fertilizer ratio.

[0003] In the prior art, through retrieval, it is found that a Chinese patent discloses "a smart soil fertility monitoring device for planting", and its application number is "202420879918.7". The above patent mainly includes an outer box and a monitoring part. The outer box includes a box body, a bracket and a handle. The monitoring part includes an intelligent monitoring system, a display control system and a soil monitoring integrated sensor. The box body is provided with a sensor connection port, a printing paper replacement port, a printing port, a heat dissipation hole and a USB interface. The intelligent monitoring system includes an A / D module, a collection control module, a data storage module, a data transmission module, a GPS module, an interaction module and a lithium battery pack. The display control system includes a touch display screen, a processor and a micro printer. Although the above device can comprehensively monitor the soil components and soil quality, provide data support for the planting precision of agricultural production, and analyze a scientific and reasonable agricultural fertilization plan. However, the root system of plum trees shows significant stratified distribution characteristics with the increase of tree age (for example, the main root depth of young trees is 20 - 30 cm, and that of adult trees can reach 30 - 40 cm). The fixed probe cannot adjust the insertion depth, resulting in the difficulty for the sensor to accurately reach the target root zone. For example, when detecting adult trees, it can only reflect the data of surface roots and cannot represent the true fertility of the deep main root zone, which may cause deviation in fertilization decisions. Therefore, the present invention provides a soil fertility detection device for plum planting to solve the problems raised in the above background art. Summary of the Invention

[0004] The purpose of the present invention is to provide a soil fertility detection device for plum planting. By stretching the extension length of the main probe, the main probe can contact the soil solution in the target root system layer, aiming at the main distribution depths of roots with different tree ages, avoiding the problem that the traditional probe is not convenient for detecting different depths due to its fixed length, especially suitable for scenarios with large variations in root depth such as mountain orchards, and has strong practicability.

[0005] To achieve the above object, a soil fertility detection device for plum cultivation is provided, including a soil fertility detector.

Two positioning components for positioning the main probe 3 are symmetrically provided at the bottom of the probe tube 2. The positioning component includes a fixing plate 6 fixedly provided at the bottom of the probe tube 2, a screw rod 7 threaded inside the fixing plate 6, a clamping plate 8 rotatably provided at one end of the screw rod 7 and in contact with the outer side of the probe tube 2, and a knob 9 fixedly provided at one end of the screw rod 7. The clamping plate 8 is of an arc structure.

[0025] In a Qingcui plum orchard, according to the main distribution depth of the roots of different tree ages, after stretching the protruding length of the main probe 3, the screw rod 7 is driven to rotate by the knob 9, so that the arc-shaped clamping plate 8 tightly presses against the main probe 3 to fix the main probe 3. Hold the soil fertility detector 1 by hand, align the bottom of the probe tube 2 with the soil area to be measured. The soil fertility detector 1 establishes a connection with the main probe 3 through the connecting wire 14, and its internal sensors (such as pH electrodes, EC sensors) contact the soil solution to collect data in real time for detection.

[0026] One side of the probe tube 2 near the bottom is provided with an external thread and a closed cover 4 is threaded thereon. The closed cover 4 covers the outside of the positioning component. The bottom of the closed cover 4 is of a conical structure. After positioning the main probe 3 by operating the screw rod 7, screwing the closed cover 4 can seal and protect many components of the positioning component, and using the conical structure at the bottom of the closed cover 4 is convenient for the downward insertion of the probe tube 2.

[0027] A limiting ring 11 is fixedly provided on the inner wall of the probe tube 2 near the bottom. The main probe 3 slides inside the limiting ring 11, and an end plate 13 is fixedly provided at the top of the main probe 3. The size of the end plate 13 is larger than that of the limiting ring 11, which can prevent the probe tube 2 from being displaced too much and pulling the connecting wire 14. A semi-circular part 5 is fixedly provided at the bottom of the main probe 3, and the diameter of the semi-circular part 5 is larger than the inner diameter of the limiting ring 11, preventing the main probe 3 from being displaced too much when retracted and squeezing the connecting wire 14.

[0028] A sealing ring 12 is fixedly provided at the top of the closed cover 4, and a sealing ring 10 is fixedly provided at the bottom of the closed cover 4. Both the sealing ring 12 and the sealing ring 10 can ensure the waterproof and airtightness at the connection between the probe tube 2 and the main probe 3, preventing the intrusion of moisture.

[0029] Both the probe tube 2 and the main probe 3 are made of stainless steel, and the surfaces of the probe tube 2, the main probe 3, the semi-circular part 5 and the closed cover 4 are all coated with a polytetrafluoroethylene coating to improve the corrosion resistance of the overall structure and better improve the service life.

[0030] Working principle: In the green crispy plum orchard, according to the main distribution depth of the roots of different tree ages, after stretching the extending length of the main probe 3, the screw 7 is driven to rotate by the knob 9, so that the arc-shaped clamping plate 8 tightly presses against the main probe 3 to fix the main probe 3;

[0031] After positioning the main probe 3 by operating the screw 7, the closing cover 4 can be screwed to enclose and protect many components of the positioning assembly, and by using the conical structure at the bottom of the closing cover 4, it is convenient for the probe tube 2 to extend downward and insert for work;

[0032] Hold the soil fertility detector 1, align the bottom of the probe tube 2 with the soil area to be measured, and a connection is established between the soil fertility detector 1 and the main probe 3 through the connecting wire 14. The internal sensors (such as pH electrode, EC sensor) contact the soil solution to collect data in real time for detection.

[0033] By stretching the extending length of the main probe 3, the main probe 3 contacts the soil solution in the target root layer. For the main distribution depths of the roots of different tree ages, it avoids the problem that the traditional probe is not convenient for detecting different depths due to its fixed length, and is especially suitable for scenarios with large variations in root depths such as mountain orchards, with strong practicability.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
