Description

Technical Field

[0001] The invention relates to the technical field of red bean planting, and in particular to a red bean fertilizing device and a fertilizing method. Background Art

[0002] Red bean is one of the main edible beans in my country. It mainly contains nutrients such as protein, sugar, starch, etc. Red bean is suitable for mixing with cereals to cook porridge or cooking, and can also be made into bean paste, cakes and desserts, etc. In addition, red bean is also beneficial for diuresis, swelling, detoxification and sore treatment.

[0003] Fertilization is very important for the cultivation of red beans. In the process of fertilization, the current practice is generally to poke a hole in the soil next to the red bean plant with a bamboo pole or a wooden pole, then put fertilizer into the hole, and then step on the hole lightly to close it.

[0004] However, the above-mentioned fertilization method is difficult, especially for the step of poking the soil hole. On the one hand, since the root system of red beans is very developed, in order to avoid damaging the root system of red beans during the poking operation, it is generally necessary to poke the soil hole 7 to 8 cm away from the bottom of the red bean plant; on the other hand, since the fertilization effect of the soil hole at a farther distance is poor, it is necessary to control the distance between the soil hole and the plant more accurately. The tools used to poke the soil hole are generally bamboo poles or wooden poles, and it is difficult to control the landing point. Therefore, the operation of poking the soil hole is difficult.

[0005] In addition, when applying fertilizer, it is difficult for bamboo or wooden poles to form the lowest point of the soil hole directly below the plant roots (generally, the lowest point of the soil hole formed by bamboo or wooden poles is usually on the side of the plant roots), and the plant roots cannot be guided to develop and extend toward the underground. The stability of the plant is poor, and it is easy to show lodging symptoms during subsequent growth. Summary of the invention

DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0041] In the present invention, unless otherwise stated, the directional words used, such as "bottom", refer to the side of the cover plate facing the ground when the red bean fertilizer application device of the present invention is in use. The directional words used, such as "inside and outside", refer to the inside and outside of a specific structural outline. The terms used, such as "first" and "second", are only used to distinguish one element from another element, and do not have order and importance. In addition, the directional words used above are only for the convenience of describing the present invention to simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as a limitation of the present invention.

[0042] Example 1

[0043] like Figures 1 to 7As shown, the present invention provides a red bean fertilizing device, comprising a first cylinder 1 and a second cylinder 2 sleeved outside the first cylinder 1, wherein the first cylinder 1 and the second cylinder 2 can rotate relative to each other. The first cylinder 1 comprises a first main body section 11 and a first drill section 12 connected to each other, wherein a first accommodating cavity 111 is formed inside the first main body section 11, wherein the first accommodating cavity 111 is used to accommodate fertilizer, wherein the first drill section 12 is configured in a conical shape, wherein a first fertilizing port 121 is provided on the outer peripheral surface of the first drill section 12, wherein the first fertilizing port 121 is communicated with the first accommodating cavity 111, and an elastic member 3 is further provided on the outer peripheral surface of the first drill section 12, wherein the elastic member 3 is arranged opposite to the first fertilizing port 121. The second cylinder 2 includes a second main body section 21 and a second drill bit section 22 which are connected to each other. The second main body section 21 and the second drill bit section 22 together form a second accommodating chamber 211 inside. The second accommodating chamber 211 is used to accommodate the first cylinder 1. The second drill bit section 22 is constructed in a conical shape. A second fertilization port 221 is provided on the outer peripheral surface of the second drill bit section 22. The second fertilization port 221 is connected to the second accommodating chamber 211, and the shape of the second fertilization port 221 matches the first fertilization port 121.

[0044] The red bean fertilizing device includes a fertilizing state and a blocking state. In the fertilizing state, the first fertilizing port 121 is connected to the second fertilizing port 221; in the blocking state, the elastic member 3 blocks the second fertilizing port 221, and at least a portion of the elastic member 3 extends out of the second fertilizing port 221.

[0045] The working principle / working process of this embodiment is as follows: the first cylinder 1 is sleeved in the second cylinder 2, and the first cylinder 1 and the second cylinder 2 can rotate relative to each other, so that the working state of the red bean fertilizing device of the present invention can be adjusted by rotating the first cylinder. When the first cylinder is not rotated (i.e., in the initial position), the red bean fertilizing device is in a blocked state, the elastic member 3 blocks the second fertilizing port 221, and a part of the elastic member 3 extends out of the second fertilizing port 221, so that after the red bean fertilizing device is inserted into the soil, a concave pit will be formed at the position corresponding to the second fertilizing port 221 (i.e., formed by the part of the elastic member 3 protruding from the second fertilizing port 221), and when the first cylinder is rotated and reaches the fertilizing state, the fertilizer falls out of the first accommodating chamber 111, passes through the first fertilizing port 121 and the second fertilizing port 221 to reach the concave pit. That is, the fertilizing work is completed.

[0046] Through the above technical solution, the red bean fertilizer device of the present application can be very conveniently used in the fertilization process of red beans. The second drill bit section 22 is inserted directly below the root system of the red bean plant at an angle inclined to the ground, and the entire fertilization operation is simple and fast. On the one hand, a sunken pit can be formed to place fertilizer, and the sunken pit is close to the root system of the plant, which can help ensure the fertilization effect; on the other hand, it can avoid damaging the root system of the red bean plant during the fertilization process, ensuring the normal growth of the red bean; on the other hand, the sunken pit formed in this way can also guide the root system of the red bean plant to develop towards the ground, improve the stability of the plant, and help enhance the anti-lodging ability of the plant.

[0047] In addition, the elastic member 3 can squeeze the soil around the second fertilization port 221 to prevent the surrounding soil from clogging the second fertilization port 221 , so that the fertilizer can fall out of the second fertilization port 221 smoothly.

[0048] In this embodiment, the first barrel 1 and the second barrel 2 can rotate relative to each other, that is, the first barrel 1 can rotate inside the second barrel 2. It can be understood that, corresponding to the first fertilizer application port 121, the second fertilizer application port 221 and the elastic member 3 also have corresponding shapes.

[0049] It should be noted that the movement process of the elastic member 3 of the present invention is as follows: in the fertilization state, the first fertilization port 121 is connected to the second fertilization port 221. Since the elastic member 3 is arranged opposite to the first fertilization port 121, the elastic member 3 is squeezed between the first cylinder 1 and the second cylinder 2. When the fertilization state is switched to the blocking state, the elastic member 3 gradually rotates to the second fertilization port 221 as the first cylinder 1 rotates. At this time, the elastic member 3 protrudes from the second fertilization port 221.

[0050] In this embodiment, the elastic member 3 is a structural member that can be elastically deformed when being squeezed by the first cylinder 1 and the second cylinder 2 .

[0051] Example 2

[0052] Based on Example 1, the elastic member 3 of the present invention may include a first end face 31 connected to the first drill bit segment 12 and a second end face 32 away from the first drill bit segment 12, the second end face 32 is constructed as a waist drum-shaped arc surface, and the diameter of the second end face 32 gradually decreases from the middle to both ends.

[0053] That is to say, the first fertilizer application opening 121 and the second fertilizer application opening 221 corresponding to the elastic member 3 are elliptical in shape, and the arcuate surface of the elliptical waist drum corresponds to each other. In this way, when the first cylinder 1 is rotated, the blocking force of the end of the elastic member 3 is smaller, which makes it easier for the first cylinder 1 to rotate.

[0054] Example 3

[0055] On the basis of Example 2, the diameters of the end faces of both ends of the elastic member 3 are zero. That is, the elastic member 3 is formed into a half-rugby ball shape, that is, a half-rugby ball shape obtained by cutting the rugby ball from the symmetry plane extending from the central axis of the rugby ball. The elastic member 3 arranged in this way is more convenient for the elastic member 3 to be gradually squeezed between the first cylinder 1 and the second cylinder 2.

[0056] Example 4

[0057] On the basis of Example 1, in the blocking state, the length of the elastic member 3 extending from the second fertilizer application port 221 is less than 3 cm. In this way, the size of the concave pit is sufficient to meet the needs of fertilization, and the elastic member 3 of such a size has less resistance when switching from the blocking state to the fertilization state, which is convenient for operators to operate.

[0058] Example 5

[0059] On the basis of Example 1, an annular groove (not shown) is formed on the inner circumferential surface of the second drill bit, the cross section of the annular groove is arc-shaped, and the annular groove is used for sliding the elastic member 3. The annular groove expands the placement space of the elastic member 3 between the first cylinder 1 and the second cylinder 2, making it easier for the elastic member 3 to slide between the first cylinder 1 and the second cylinder 2. In addition, the difficulty of rotating the first cylinder 1 can be reduced to a certain extent.

[0060] Example 6

[0061] On the basis of any one of Embodiments 1 to 5, an end of the first main body section 11 away from the first drill bit section 12 is connected to an operating rod 13, the operating rod 13 and the first main body section 11 are perpendicular to each other, and the operating rod 13 is located above the second main body section 21;

[0062] A limiting structure is provided at one end of the second main body section 21 away from the second drill bit section 22, and the limiting structure includes a first limiting block 41 and a second limiting block 42 which are arranged opposite to each other. In the fertilizing state, the operating rod 13 abuts against one of the first limiting block 41 and the second limiting block 42, and in the blocking state, the operating rod 13 abuts against the other of the first limiting block 41 and the second limiting block 42.

[0063] The operating rod 13 arranged in this way is easier for the operator to hold, thereby being able to rotate the first cylinder 1 more conveniently.

[0064] Since the first fertilization port 121 and the elastic member 3 are arranged relative to each other, the first cylinder 1 is sleeved in the second cylinder 2, and the entire device is located inside the soil during fertilization, and it is difficult to determine its rotation angle during rotation. The first limit block 41 and the second limit block 42 can play a role of limiting and prompting. For example, during the rotation process, the operating rod 13 butts against the first limit block 41, which is the fertilization state, and the operating rod 13 butts against the second limit block 42, which is the blocking state. Then, the operator does not need to see the connectivity between the first fertilization port 121 and the second fertilization port 221, which is sufficient to judge its status, which is very convenient.

[0065] Example 7

[0066] On the basis of Example 6, the red bean fertilizing device also includes a cover plate 5, the bottom surface of the cover plate 5 is connected to the second main body section 21 and / or the limiting structure, and the bottom surface of the cover plate 5 is against the first main body section 11.

[0067] The cover plate 5 is used to limit the axial displacement of the first cylinder 1 to prevent the first cylinder 1 from moving axially due to misoperation or the like during operation, thereby enhancing the usability and misoperation prevention capability of the present invention.

[0068] Example 8

[0069] On the basis of Example 7, in the axial direction of the first main body section 11, at least a portion of the projection of the first accommodating cavity 111 exceeds the projection of the cover plate 5. In other words, the cover plate 5 cannot completely cover the first accommodating cavity 111, and when fertilizer is put in, it can be put in from the part of the first accommodating cavity 111 that is not blocked by the cover plate 5.

[0070] Alternatively, the cover plate 5 is detachably connected to the second main body section 21 and / or the limiting structure. In this way, the cover plate 5 can be removed to facilitate cleaning of the entire device.

[0071] Example 9

[0072] With the advancement of technology, harvesters are often used to harvest mature red beans in large-scale planting scenarios. However, in order to ensure harvesting efficiency and prevent the harvester's knives from being damaged by hard objects such as stones in the ridges, the harvester's knives are generally required to be set farther from the ground. This will cause the pods at the bottom of the red bean plant to be unable to be harvested or to be damaged or scraped off by the knives, which not only causes a waste of resources, but also affects the yield to a certain extent.

[0073] According to another aspect of the present invention, there is also provided a fertilization method, which is applied to the red bean fertilization device described in any one of the above technical solutions, and the fertilization method comprises:

[0074] Germination: placing a cushion layer at the bottom of a germination tank, the cushion layer being a paper towel or a towel, placing red bean seeds on the cushion layer, injecting clean water at 30°C to 40°C into the germination tank to soak the red bean seeds for 1 to 2 hours, wherein the depth of the clean water is 1 / 2 to 2 / 3 of the height of the red bean seeds; after soaking, draining the clean water, and injecting 0.01 to 0.1 wt% of Telmay AC94377 solution into the germination tank for secondary soaking, and the secondary soaking time is 72 to 96 hours;

[0075] Such a germination step can not only promote the rapid germination of red bean seeds, but also enable the seed epidermis of red bean to carry a certain amount of nutrients, which can effectively increase the length of the first internode at the time of emergence after the seedlings emerge.

[0076] Promoting the stem growth: When the red bean seedlings enter the three true leaf stage, applying compound fertilizer to the red bean seedlings, the compound fertilizer is a mixture of aminoethyl hexanoate powder, powdered carbodiamide, and powdered ammonium dihydrogen phosphate; the ratio of the aminoethyl hexanoate powder, powdered carbodiamide, and powdered ammonium dihydrogen phosphate is 0.0001:1:0.01 to 0.0001:1:0.1, and then putting the compound fertilizer into the red bean fertilizing device, and using the red bean fertilizing device to fertilize the red bean seedlings;

[0077] The compound fertilizer can effectively promote the rapid growth of red beans, and can further increase the length of the first internode of red beans. Moreover, the fertilizer applied by the red bean fertilization device is located directly below the root system of the plant, which helps to guide the root system of the red bean to develop and extend toward the ground, thereby making it grow healthier and stronger.

[0078] Growth promotion: When the red bean plants enter the flower bud differentiation stage, gibberellin and sodium nitrophenolate are applied to the red bean plants; the concentration of gibberellin is 0.001-0.005wt%, and the application amount is 45-55L / mu; the concentration of sodium nitrophenolate is 0.01wt%-0.05wt%, and the application amount is 45-55L / mu;

[0079] The above fertilization will not cause the red bean stems to grow too long, while effectively promoting the growth of the red bean.

[0080] Anti-lodging: After the red bean plants bloom and form pods, apply cypermethrin to the plants; the spraying standard of cypermethrin is: 3g~6g / mu.

[0081] The above-mentioned mepiquat can effectively inhibit the phenomenon of excessive growth and elongated stems of adzuki beans and enhance the ability of adzuki bean plants to resist lodging.

[0082] The adzuki bean fertilization method provided by the present invention can effectively increase the length of the first internode of adzuki bean in the bud raising stage and the stem promoting stage, and increase the lowest pod-forming position (that is, the position of the pods at the lowest position is higher). Then, during the flower bud differentiation period, growth-promoting fertilization is performed to accelerate the growth, so that the length of the pod-forming stalk reaches a higher degree, and the pod-forming position is located in the lower middle position of the plant as a whole, which is more concentrated and convenient for harvesting (or picking). Moreover, the overall center of gravity of the plant is lower, and lodging is not easy to occur. After flowering and pod formation, the application of mepiquat can inhibit the continued growth of the adzuki bean stalk, strengthen the development of the stalk, and improve its development effect, so as to further improve the ability of red beans to resist lodging.

[0083] Example 10

[0084] On the basis of Example 9, the method further includes a foliar fertilization step, in which a potassium dihydrogen phosphate solution with a mass fraction of 0.1%-0.15% is used for foliar spray fertilization during the early flowering period of red beans.

[0085] Foliar fertilization can promote flower bud differentiation and plant growth of red beans, and improve yield and quality.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0087] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0088] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
