Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of field green prevention and control, especially to a clematis fruticosa winter seedling raising device. BACKGROUND

[0002] Utilizing natural enemy pests to control tobacco pests is one of the important ways of tobacco green prevention and control, which can effectively reduce the pesticide use amount and reduce tobacco pesticide residues. But due to the existence of multiple pest outbreak periods in the tobacco growth process and the time window between different pest outbreak periods, and the migration of diseases and pests in field planting and greenhouse test, in order to achieve good pest control effect, it is necessary to release natural enemy pests multiple times, but the fact is that the release cost of natural enemy pests is high, which is difficult to meet the actual needs.

[0003] In view of this problem, the prior art has the technology of planting conservation plants between plots and providing food for the released natural enemy pests in the pest empty window period by setting the flowering period and using nectar, so that the natural enemy pests can stay until the next pest outbreak period. Clematis fruticosa is a commonly used conservation plant, which has the characteristics of long flowering period and strong vitality. In the specific operation, it is cultivated in the tobacco seedling raising greenhouse in winter, transplanted to the ridged tobacco field after spring and can ensure the flowering period in April, provide nectar conservation for the natural enemy pests that have eaten up the aphids of wheat seedlings, and then the natural enemy pests can kill the tobacco aphids that break out in May and June and the tobacco whitefly that breaks out in July.

[0004] But in the process of transplanting clematis fruticosa, there are the following problems: clematis fruticosa seedlings are plants with developed main roots but undeveloped lateral roots, and the whole root system has poor holding effect on nutrient soil. Although plastic bags and other tools are used for wrapping, the root system is still easy to separate completely from rhizosphere soil during transplanting and reduce the survival rate after transplanting. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a clematis fruticosa winter seedling raising device. The utility model has the advantages of simple structure, effective wrapping of rhizosphere soil (nutrient soil) of clematis fruticosa by open and close type seedling raising cup combined with net bag structure, and complete transplanting effect, which ensures the transplanting survival rate of clematis fruticosa.

[0006] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0007] A clematis fruticosa winter seedling raising device, the device comprises two half cylinders which are the same in shape and symmetrically arranged and connected at the bottom by a flexible belt, and the two half cylinders are connected in a butt joint state to form a seedling raising cup structure with an open top and a bottom closed by a flexible belt.

[0008] The seedling raising cup structure is internally lined with a net bag structure for wrapping nutrient soil.

[0009] Preferably, the flexible strip has through holes for air and water permeability.

[0010] Preferably, the mesh bag structure includes a mesh bag body and an elastic band integrally disposed at the opening of the mesh bag body.

[0011] Preferably, both of the two semi-cylinders are provided with hanging rods on the top of their opposite side walls for supporting rubber band rings, and the hanging rods are L-shaped plate structures with their ends bent downwards.

[0012] Preferably, the two semi-cylinders are provided with a support rod at the top of the side wall of the joint for supporting the rubber band ring.

[0013] Preferably, the rubber band is also integrally provided with a carrying rope.

[0014] The working process of this utility model is as follows:

[0015] Before sowing, the two halves of the tube are joined together and combined with a flexible band to form a seedling cup structure with an open top. Then, the mesh bag structure is attached to the inner wall of the seedling cup and filled with seedling nutrient soil (i.e., substrate). Finally, the rubber band is stretched open and put inside out on the outer wall of the top of the seedling cup structure. The elasticity is used to tighten and shape the seedling cup. At the same time, the mesh bag body and the rubber band on the outer wall of the seedling cup are also limited by the hanging rod and the support rod, so they will not collapse and return to their original position. Then, the seeds are planted in the nutrient soil (i.e., substrate) and the seedlings are raised until the transplanting period.

[0016] Before transplanting, separate the rubber band from the top of the seedling cup, separating the two halves of the seedling cup to expose the seedling nutrient soil (i.e., substrate) completely covered by the mesh bag structure, as well as the Cnidium monnieri seedlings rooted in the nutrient soil (i.e., substrate). Use a carrying rope to move it to the pre-reserved seedling hole in the field and backfill with soil to complete the transplanting.

[0017] If the mesh of the net bag structure is small, the bottom of the net bag structure can be cut open before transplanting into the seedling hole to prevent it from interfering with the growth of the main root of Cnidium monnieri.

[0018] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure. By using an openable seedling cup in conjunction with a mesh bag structure, it can effectively cover the root zone soil (nutrient soil) of Cnidium monnieri and achieve complete transplanting, thus ensuring the survival rate of transplanted Cnidium monnieri.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figs. 1-3 As shown, a winter seedling raising device for Cnidium monnieri includes two identical and symmetrically arranged semi-cylinders 11 connected at the bottom by a flexible strip 12. The two semi-cylinders 11 form a seedling cup structure 1 with an open top and a closed bottom by a flexible strip when they are joined together. The flexible strip 12 has through holes for air and water permeability.

[0024] The seedling cup structure 1 is lined with a mesh bag structure 2 for covering the nutrient soil. Therefore, the mesh bag structure 2 includes a mesh bag body and an elastic band 21 integrally set at the opening of the mesh bag body. The elastic band 21 is also integrally provided with a carrying rope 22.

[0025] Both of the two semi-cylinders 11 are provided with hanging rods 13 on the top of their opposite side walls for supporting the rubber band rings 21. The hanging rods 13 are L-shaped plate structures with the ends bent downwards. Both of the two semi-cylinders 11 are provided with support rods 14 on the top of their side walls at the joint for supporting the rubber band rings.

[0026] The working process of this utility model is as follows:

[0027] Before seedling cultivation, the two half-cylinders 11 are joined together and combined with the flexible belt 12 to form a seedling cup structure 1 with an open top. Then, the mesh bag structure 2 is attached to the inner wall of the seedling cup and filled with seedling nutrient soil (i.e., substrate). Finally, the rubber band ring 21 is stretched open and put on the outer wall of the top of the seedling cup structure. The elasticity is used to tighten and shape the seedling cup. At the same time, the mesh bag body on the outer wall of the seedling cup and the rubber band ring 21 are also limited by the hanging rod 13 and the support rod 14, so they will not collapse and return to their original position.

[0028] Then, plant the seeds in the nutrient soil (i.e., substrate) and raise the seedlings until transplanting.

[0029] Before transplanting, separate the rubber band 21 from the top of the seedling cup, separating the two halves 11 of the seedling cup and exposing the seedling nutrient soil (i.e., substrate) completely covered by the mesh bag structure, as well as the Cnidium monnieri seedlings rooted in the nutrient soil (i.e., substrate). Use a carrying rope to move them to the pre-reserved seedling holes in the field and backfill with soil to complete the transplanting.

[0030] If the mesh size of the net bag structure 2 is small, the bottom of the net bag structure can be cut open before transplanting into the seedling hole to prevent it from interfering with the growth of the main root of Cnidium monnieri. This invention is simpler to implement than the plastic bag wrapping method used in the prior art, and significantly improves the survival rate.
