Description

Technical Field

[0001] The utility model relates to the technical field of rice planting, in particular to a rice seedling raising tray for both throwing and transplanting rice seedlings. Background Art

[0002] Rice seedlings are generally grown indoors in rice seedling trays to overcome the shortcomings of early field seedling cultivation, such as low temperature, many weeds, many pests and diseases, and slow growth. When the seedlings are mature, they need to be taken out of the seedling trays and then sown in the fields. There are two ways to plant the seedlings in the seedling trays into the fields. One is to manually take them out of the seedling trays and plant them in the fields; the other is to take the seedlings out of the seedling trays and throw them into the fields using a seedling thrower.

[0003] In order to improve the quality and efficiency of rice seedlings transplanting and ensure the high yield of rice seedlings transplanting, more and more farmers use rice transplanting machines for mechanized rice seedling transplanting. Raising rice seedlings is a key link in the high-yield cultivation technology system of rice seedlings transplanting. Compared with conventional rice seedling raising methods, the most notable feature of rice seedlings transplanting is that the seedling recovery period after mechanized planting is very short, and the seedlings can quickly return to green and tiller. Rice seedlings transplanting must use a seedling tray that is specially adapted to the transplanting of rice seedlings transplanting as a special tool for raising seedlings. The technical requirements for raising rice seedlings by machine throwing are high, and the technical requirements for the special soft tray for raising rice seedlings by machine throwing are high to ensure that the rice seedlings transplanted by machine throwing are adapted to the technical requirements of transplanting by the transplanting machine. The seedling tray of the machine throwing rice seedlings currently generally adopts a soft seedling tray design to adapt to the characteristics of the seedling tray that needs to be bent during the process of entering and exiting the rice transplanting machine, and the seedling tray structure is designed according to the structural characteristics of the existing transplanting machine such as the spacing between rows and plants.

[0004] In order to increase the number of seedlings per mu, reduce the number of seedling trays used per mu, reduce the size of the seedling holes, and the seedling holes on the seedling tray are closely distributed, such as a new type of rice seedling throwing soft tray disclosed in the patent document with application number 202023056274.2. The seedling tray has low support strength, which is not conducive to the transportation and transfer of the seedling tray, and the seedling holes are relatively isolated, and it is difficult to ensure the consistency of water in the seedling holes of the same seedling tray. The seedling space in the seedling holes is small, and only a small amount of cultivation soil can be filled, resulting in insufficient water and fertilizer in the matrix in the holes, a small number of seeds that can be accommodated in the holes, an insufficient number of seedlings per seedling, a large number of empty seedling holes without seedlings, and poor growth during subsequent transplanting and planting. When the seedling thrower is transplanted, the basic seedlings are too few and easy to float, and the roots of the seedlings are exposed outside the soil, resulting in a reduced survival rate of the seedlings.

[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] Combination Figure 1-Figure 4 The present embodiment provides a dual-purpose rice seedling raising tray for broadcasting rice seedlings.

[0026] In the following embodiment, a first direction x, a second direction y and a third direction z that intersect each other are introduced, wherein the first direction x is parallel to the length direction of the rice seedling raising tray for dual-purpose rice seedling casting, the second direction y is parallel to the width direction of the rice seedling raising tray for dual-purpose rice seedling casting, and the third direction z is parallel to the thickness direction of the rice seedling raising tray for dual-purpose rice seedling casting.

[0027] The present embodiment provides a rice seedling raising tray for both throwing and transplanting rice seedlings. Figure 1-Figure 4 As shown, it comprises: a seedling raising tray body 1, on which a plurality of seedling raising grooves 2 arranged in a matrix are arranged. A connecting block 3 is arranged between two adjacent seedling raising grooves 2 in the same row, and the connecting block 3 is arranged protruding from the upper surface of the seedling raising tray body 1. Two adjacent seedling raising grooves 2 in the same column are connected by a connecting groove 4, which is arranged concave on the upper surface of the seedling raising tray body 1, and the depth of the connecting groove 4 is less than the depth of the seedling raising groove 2. Figure 1 It can be seen that the multiple seedling raising grooves 2 arranged along the first direction x are in the same row; the multiple seedling raising grooves 2 arranged along the second direction y are in the same column. The depth of the seedling raising grooves 2 and the thickness direction of the seedling raising tray are arranged along the third direction z.

[0028] The rice seedling raising tray for both throwing and transplanting in this embodiment is provided with a connecting block 3 between two adjacent rice seedling raising grooves 2. The connecting block 3 can strengthen the overall strength of the rice seedling raising tray, prolong the service life, and facilitate the handling and transfer of the rice seedling raising tray. In addition, the multiple connecting blocks 3 are arranged at intervals, so that the rice seedling raising tray has a certain bending performance, which is convenient for taking out the rice seedlings when throwing by machine or manually. In addition, by connecting the two rice seedling raising grooves 2 through the connecting groove 4, the water in the rice seedling raising grooves 2 can move to each other, so that the water content in the multiple rice seedling raising grooves 2 is kept consistent, so that the rice seedlings are cultivated in a similar growth environment, and the consistency of the cultivated rice seedlings is maintained; and the arrangement of the connecting groove 4 facilitates the seeds to be evenly dispersed to each rice seedling raising groove 2 through the connecting groove 4 in the early stage of rice seedling raising, thereby improving the dispersion efficiency.

[0029] In some embodiments, the connecting block 3 is gradually widened from the middle to both ends, and the length of the connecting block 3 is equal to the upper opening diameter of the seedling raising groove 2. The connecting block 3 is arranged between the two seedling raising grooves 2 to avoid the opening of the seedling raising grooves 2, which plays a role in strengthening the seedling raising tray and reduces mutual interference between the two adjacent seedling raising grooves 2, which is conducive to raising and removing seedlings.

[0030] In some embodiments, the seedling raising trough 2 is an expanded cylindrical structure with a diameter gradually decreasing from top to bottom, which is convenient for taking out the seedlings after cultivation is completed and also convenient for sowing in the seedling raising trough 2.

[0031] In some embodiments, drainage holes are provided on the bottom surface of the seedling raising groove 2, so as to keep the moisture in the seedling raising groove 2 constant through the drainage holes during the seedling raising process. The drainage holes can be used for drainage or water entering from the bottom of the seedling raising groove 2.

[0032] In some embodiments, the seedling tray body 1 is a polypropylene tray body. The seedling tray body 1 adopts a soft disk design to meet the technical requirements of the seedling throwing machine for bending the soft disk in and out to complete the seedling throwing operation. Since polypropylene has the advantages of light weight, high strength and low price, it can achieve enhanced rigidity while saving manufacturing costs. In addition, the seedling tray body 1 can also be made of other soft materials, such as silicone, rubber, etc.

[0033] In some embodiments, Figure 4 As shown, the angle between the side wall of the seedling raising groove 2 and its bottom surface is α, 90°<α≤150°. The angle α can be 95°, 120°, 130°, 150°, etc.

[0034] In some embodiments, Figure 3 and Figure 4As shown, the diameter of the upper opening of the seedling raising groove 2 is a, 2mm≤a≤2.5mm, and the diameter of the bottom end of the seedling raising groove 2 is b, 1mm≤b≤1.5mm. The disc thickness of the seedling raising disc body 1 is d, 1cm≤d≤5cm. Preferably, a is 2cm, 2.1cm, 2.2cm, 2.5cm, etc.; b is 1cm, 1.1cm, 1.2cm, 1.5cm, etc.; d is 1cm, 2cm, 3cm, 5cm, etc.

[0035] The existing floppy disk structure used for machine seedling throwing is: 64cm long, 40.5cm wide, 2.5cm deep; 13 rows per disk, 32 holes per row, 416 holes in total; each hole has an upper diameter of 1.5cm, a bottom diameter of 0.75cm, and a hole depth of 2.5cm. The volume of the holes is small, and during the use of seedlings, there are problems such as insufficient total amount of matrix per hole, insufficient water and fertilizer in the matrix in the hole, insufficient number of seeds that can be accommodated in the hole, insufficient number of seedlings per stump, too many empty stump holes without seedlings, and too few basic seedlings that are easy to float when transplanted by the seedling thrower. Due to the above reasons, when the seedling thrower is used for machine planting, the proportion of seedling trays that truly meet the standard seedling requirements of the seedling thrower is not high, and manual throwing has to be performed.

[0036] The preferred structure of the seedling tray in this embodiment is: length n is 64cm, width m is 40.5cm, seedling raising groove depth is 2.5cm, and seedling raising tray thickness d is 5cm; each tray has 13 rows and 27 seedling raising grooves in each row, a total of 351 seedling raising grooves, which is 65 holes less than the 416 holes of the original seedling tray, and the upper opening diameter a of each seedling raising groove of the seedling raising tray is 2.1cm, and the bottom diameter b is 1.33cm; the capacity of each seedling raising groove is increased, and the overall hardness is significantly increased. The capacity of each seedling raising groove of the seedling throwing tray of this embodiment is significantly increased, and the number of seedlings, substrates, and water and fertilizer carried by each seedling throwing machine are more, heavier, and stronger, which is more suitable for machine throwing and hand throwing seedling planting operations, and the quality of throwing is improved, the basic seedlings are significantly increased, and the yield increase effect is obvious.

[0037] The upper opening diameter a of the seedling raising trough is 2.1 cm, and the bottom diameter b is 1.33 cm, so that the substrate and seeds (especially long-grain seeds) can enter the seedling raising trough more easily during the sowing process, thereby better increasing the number of substrates and seeds in each seedling raising trough.

[0038] The depth of the seedling raising groove is 2.5cm, which is the same as the original hole depth, which can better ensure that the seedling raising tray of this embodiment can adapt to the technical specification requirements of various existing seedling throwing machines for the thickness of the soft disk. The number of longitudinal rows of seedling raising grooves is 13, which is the same as the number of longitudinal rows of each original plate, which can better ensure that the seedling raising tray of this embodiment can adapt to the technical parameter requirements of the number of rows that can be thrown by the soft disk for the existing seedling throwing machine operation. The number of transverse seedling raising grooves is 27, which can better meet the space requirements of each seedling raising groove in length after the seedling raising groove in this embodiment is enlarged, and achieve the main technical goal of increasing the substrate and the number of plants per seedling.

[0039] The rice seedling raising tray of this embodiment can take into account both rice seedling raising methods of machine throwing and hand throwing at the same time, can increase the proportion of rice seedlings that can be thrown by machine, significantly improve the quality of machine thrown rice seedlings, and give full play to the positive role in improving the quality of machine thrown rice seedling raising and the actual use of the rice seedling throwing machine.

[0040] The seedling tray of this embodiment is used to increase the number of seedlings per plant by machine-casting, and the aperture of the seedling raising groove on the seedling tray is increased, which not only makes it easier to sow long-grain high-quality rice seeds into the seedling raising groove, but also significantly increases the number of seeds that can be accommodated in each seedling raising groove. It has a very obvious effect on increasing the basic seedlings during the early rice seedling raising when broadcasting, which mainly adopts conventional rice varieties and doubles the amount of seeds per mu. It is beneficial to ensure the basic seedlings and achieve small-planted dense planting, laying a solid foundation for establishing a reasonable high-yield structure. At the same time, due to the significant increase in the base mass of each hole, the water and fertilizer capacity of each hole is increased synchronously, which is effective in increasing the water and fertilizer supply of the seedlings in the hole, enhancing the water and fertilizer conservation effect, achieving the growth advantage of the seedlings, and improving the quality of the seedlings. By cultivating strong seedlings for broadcasting, high-quality strong seedlings are provided for the increase in production after broadcasting.

[0041] The length and width specifications of the seedling tray of this embodiment are the same as those of the original seedling tray. While meeting the requirements of machine throwing, the hole volume and hole spacing of the seedling raising trough are increased, which increases the overall hardness of the seedling raising tray and extends its service life.

[0042] The rice seedling raising tray of the present embodiment has a simple structure, is easy to manufacture, and is easy to promote, and is particularly suitable for both machine throwing and hand throwing of rice seedlings.

[0043] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
