Description

Technical Field

[0001] The utility model relates to the technical field of seedling cultivation, in particular to a seedling cultivation covering blanket made of crop straws. Background Art

[0002] The seedling cover blanket is a new type of seedling raising technology tool. It is usually a blanket-like material made of non-woven technology. It can be covered on the seedbed to keep warm, keep moisture, prevent pests and diseases, promote soil ventilation, etc., so as to improve the seedling raising environment and improve the growth quality and survival rate of seedlings. The emergence of seedling cover blanket technology has improved the seedling raising environment through physical means, improved the growth quality and survival rate of seedlings, and solved the problems of soil pollution, pests and diseases, and low survival rate often faced by traditional seedling raising methods. Therefore, it is widely used in various planting scenarios.

[0003] As the technology continues to mature, the rice seedling blanket made of crop straw has shown more advantages than rice seedling blankets made of other materials. First of all, as a natural organic material, crop straw is rich in organic matter and nutrients. By converting it into a rice seedling blanket, these organic components can continuously provide nutrients to the soil, help improve soil structure, and increase soil fertility. Secondly, as an agricultural waste, using straw to make rice seedling blankets also has environmental significance. It can reduce environmental pollution and realize the recycling of resources. It is in line with the development concept of green agriculture and helps promote the sustainable development of agricultural production.

[0004] For example, the patent document with application number CN202321074354.1 discloses a discless seedling blanket. By adding a design of a degradable seedling blanket, and through the coordinated use of a composite blanket bottom and a hard blanket edge, and the coordinated use of a hard blanket edge and a positioning rod, multiple seedling blankets can be stacked together, making it convenient to stack the seedling blankets after placing nutrient soil and seeds. At the same time, because the material of the composite blanket bottom is rice straw and rice husk ground and processed at high temperature, the composite blanket bottom is gradually decomposed during use and absorbed by the seedlings, so there is no need to clean up the seedling pots after the seedling cultivation is completed.

[0005] However, the existing rice seedling raising blanket technology similar to the above application also has some defects:

[0006] In the prior art, although the seedling covering blanket made of crop straw will continue to decompose over time, its decomposition speed is far slower than the speed of seed rooting and germination. The undecomposed seedling covering blanket will hinder the rooting and germination of the seeds. The roots of the seeds must pass through the covering blanket to penetrate the ground, and the young shoots of the seeds must also pass through the covering blanket to extend out of the ground.

[0007] Therefore, it is urgent to improve this shortcoming. The utility model is to study and improve the existing structure and shortcomings, and provide a rice seedling covering blanket made of crop straw. Utility Model Content

DETAILED DESCRIPTION

[0027] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] like Figure 1-Figure 6 As shown, a seedling raising covering blanket made of crop straw comprises an upper straw blanket 1 and a lower straw blanket 2, and the upper straw blanket 1 and the lower straw blanket 2 are made of crop straw, the upper straw blanket 1 comprises an upper blanket body 11, a soil holding trough 12, a separation membrane 13, air holes 14, straw cross bars 15 and straw longitudinal bars 16, and the top of the upper blanket body 11 is provided with a soil holding trough 12, and the bottom of the soil holding trough 12 is fixedly connected with the separation membrane 13, and the bottom of the separation membrane 13 is provided with air holes 14, the interior of the soil holding trough 12 is fixedly installed with a straw cross bar 15, and the interior of the soil holding trough 12 is fixedly installed with a straw longitudinal bar 16, and the straw longitudinal bar 16 is located below the straw cross bar 15, and both ends of the straw cross bar 15 are fixedly connected to the inner wall of the soil holding trough 12, and the straw cross bars 15 are equidistantly arranged on the soil holding trough 12. , and the straw cross bars 15 are parallel to each other, both ends of the straw longitudinal bars 16 are fixedly connected to the inner wall of the soil trough 12, and the straw longitudinal bars 16 are equidistantly arranged inside the soil trough 12, and the straw longitudinal bars 16 are parallel to each other, the lower straw blanket 2 is arranged at the bottom of the upper straw blanket 1, and the lower straw blanket 2 includes a lower blanket body 21, a seeding trough 22, a partition net 23 and a positioning plug-in 24, a seeding trough 22 is opened on the top of the lower blanket body 21, and the bottom of the seeding trough 22 is fixedly connected with the partition net 23, and the four corners of the lower blanket body 21 are fixedly installed with positioning plug-ins 24, the soil trough 12 and the seeding trough 22 are arranged one by one, and the outer surface of the soil trough 12 is completely fitted with the inner surface of the seeding trough 22, and the shape and size of the soil trough 12 and the shape and size of the seeding trough 22 are matched with each other;

[0029] The specific operation is as follows: the seeds are scattered into the seed placement groove 22, and the seeds fall on the partition net 23. Then, the upper blanket body 11 is covered on the lower blanket body 21, and the bottom of the soil storage groove 12 is inserted into the inner side of the seed placement groove 22, so that the seeds can be located between the partition net 23 and the partition membrane 13. Then, the nutrient soil is spread on the top of the upper straw blanket 1 and flattened. The nutrient soil enters the soil storage groove 12 during the flattening process. After sowing, water is poured on the top of the upper straw blanket 1. The water penetrates into the nutrient soil in the soil storage groove 12 and soaks the seeds through the partition membrane 13 and the air vents 14. The straw cross bars 15 and the straw longitudinal bars 16 in the soil storage groove 12 are decomposed. Before, it can play the role of layered support of nutrient soil inside the soil holding trough 12, avoiding the sinking and agglomeration of nutrient soil caused by continuous watering, which is conducive to keeping the nutrient soil loose, so that the leaf buds grown by crops can easily break through the separation membrane 13 and the soft nutrient soil and extend upward, and the roots of crops can directly penetrate into the ground through the pores of the seed placement trough 22. In addition, since the upper straw blanket 1 and the lower straw blanket 2 made of crop straw have the property of being degradable, they can be gradually decomposed during use and provide nutrition for the seedlings. Therefore, when the crops are fully grown, the upper straw blanket 1 and the lower straw blanket 2 will also be completely decomposed.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the upper straw blanket 1 also includes positioning holes 17 and plugs 18, and the positioning holes 17 are opened at the four corners of the top of the upper blanket body 11, and the top of the upper blanket body 11 is connected with the plugs 18 through the positioning holes 17, and the plugs 18 include a limit plate 181 and a plug rod 182, and the bottom of the limit plate 181 is fixedly connected to the top of the plug rod 182, and the four corners of the lower blanket body 21 are fixedly installed with positioning plugs 24, and the positioning plugs 24 include anchor rods 241, connectors 242 and a socket 243, and the top of the anchor rod 241 is fixedly connected with a connector 242, and the inner surface of the connector 242 is fixedly connected to the outer surface of the lower blanket body 21, and the anchor rod 241 is fixedly connected to the lower blanket body 21 through the connector 242, and a socket 243 is provided at the top of the anchor rod 241, and the upper straw blanket 1 is fixed to the top of the lower straw blanket 2 through the plug 18 and the positioning plug 24, and the plug 18 and the positioning plug 24 constitute a snap-fit ​​plug structure;

[0031] The specific operation is as follows: four positioning plugs 24 are inserted into the soil in sequence. Since the bottom end of the anchor rod 241 is a pointed cone, it can be easily inserted into the ground. The lower blanket body 21 is fixed by using the positioning plug 24, so that the lower straw blanket 2 is evenly covered on the soil, thereby improving the stability of the lower straw blanket 2 and preventing it from shifting during the growth of crops. In addition, after the upper straw blanket 1 is stacked on top of the lower straw blanket 2, the upper straw blanket 1 on the top of the lower straw blanket 2 can be fixed by inserting the bottom end of the plug 18 through the positioning hole 17 into the plug hole 243, thereby enhancing the connection effect of the upper straw blanket 1 and the lower straw blanket 2, and improving the stability of the upper straw blanket 1 and the lower straw blanket 2 after overlapping and stacking.

[0032] In summary, according to Figure 1-Figure 6 As shown in the figure, the working principle of the seedling raising blanket made of crop straw is as follows: first, four positioning plugs 24 are inserted into the soil in sequence so that the lower blanket body 21 is evenly covered on the soil, and then the seeds are scattered into the seed placement groove 22, and the seeds fall on the partition net 23, and then the upper blanket body 11 is covered on the lower blanket body 21, and the bottom of the soil storage groove 12 is inserted into the inner side of the seed placement groove 22. At this time, the partition membrane 13 just covers the seeds, and then the four plugs 18 are aligned with the positioning holes 17 and inserted in sequence, so that the insertion rod 182 is completely immersed in the insertion hole 243, and the upper blanket body 11 is fixed on the lower blanket body 21, and then the upper straw blanket 1 is laid on the top. The nutrient soil is sprinkled and flattened. During the flattening process, the nutrient soil enters the soil trough 12 to complete the sowing operation. In order to meet the seed germination needs, water can be poured on the top of the upper straw blanket 1. The water seeps into the nutrient soil in the soil trough 12 and soaks the seeds through the separation membrane 13 and the air holes 14. Before the straw cross bars 15 and the straw longitudinal bars 16 are decomposed, the nutrient soil can be supported in layers inside the soil trough 12. As time goes by, the seeds germinate, and their roots can directly penetrate into the ground through the pores of the seed placement trough 22, and the leaf buds can directly break through the separation membrane 13 and stretch upward. When the crops are fully grown, the upper straw blanket 1 and the lower straw blanket 2 will also be completely decomposed.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
