Description

Technical Field

[0001] The invention belongs to the field of planting pots, in particular to a planting pot for large root system experimental materials in the seedling stage. Background Art

[0002] During the planting process of experimental materials, due to the limited space in the incubator and climate chamber, overly large planting pots are often not selected. However, experimental materials with large root systems (such as corn) have well-developed root systems and grow faster during the growth process. During the seedling planting process, the roots often extend out of the planting pots from the lower water absorption holes, affecting the growth state of the experimental materials. First, the roots grow out, and the roots will break during the movement of the experimental materials in the later stage, affecting the growth state of the plants. In addition, untimely watering will cause the extended roots to be exposed to a dry air environment, causing drought stress, which will affect the accuracy of the subsequent experimental material parameter determination.

[0003] Drought and high temperature are common adverse stresses in nature and are also important scientific issues in crop research. During the planting process of large root system experimental materials, the roots have the characteristic of growing on the wall and will gather in large numbers on the wall of the planting pot. During drought or high temperature treatment, the environment in which the roots attached to the wall are located is more severe, and the soil moisture content and temperature are quite different from the environment in which the internal roots are located. It is not possible to accurately quantify and truly reflect the degree of stress, which is not conducive to the development of subsequent experiments. Summary of the invention

[0004] The invention provides a seedling planting pot for large root system experimental materials, so as to solve the defects in the prior art.

[0005] The present invention is achieved through the following technical solutions:

[0006] The seedling planting pot for large root system experimental materials includes an outer pot and an inner pot with openings upward and the same shape. The bottom surface of the outer pot is provided with water absorption holes. The side and bottom surfaces of the inner pot are 300-mesh metal grids. The inner pot and the outer pot are detachably fixedly connected by a connector.

[0007] When the present application is in use, the inner pot is placed in the outer pot, the premixed soil or matrix vermiculite is mixed and evenly placed in the inner pot and in the gap between the inner pot and the outer pot, a small hole is inserted in the soil in the inner pot, and seeds are placed in the soil. The seeds are placed at a depth of 1-2 cm, and the soil is lightly covered. The seeds are placed on a tray and placed in a culture room for growth. Since the inner pot is a 300-mesh metal grid, the roots can grow within an effective range without sticking to the outer wall, and at the same time, the roots' absorption of water and fertilizer will not be affected, which is conducive to the subsequent drought or high temperature stress experiments.

[0008] Preferably, the outer pot is covered with a shading layer along its side, which can prevent sunlight from entering the outer pot and effectively prevent the water in the soil in the outer pot from evaporating.

[0009] Preferably, the bottom surface of the outer pot is fixedly connected with a bottom plate of a 300-mesh metal mesh, and the metal mesh covers the water absorption holes. The bottom plate can ensure that the outer pot can be used alone when the inner pot is not placed, and effectively prevents the roots from extending through the water absorption holes.

[0010] Preferably, the connecting member comprises a hollow column and a plug rod, the hollow column is vertically connected to the inner wall of the bottom surface of the outer basin, the columns are distributed around the inner wall of the bottom surface of the outer basin, the plug rods are respectively inserted into the corresponding columns and the upper ends of the plug rods are fixedly connected to the bottom surface of the inner basin. The plug rod is inserted into the hollow column, so that the inner basin can be confined in the outer basin and can be separated from the outer basin by pulling upwards. At the same time, the distance between the inner basin and the outer basin is the height of the hollow column, so that the bottom surface of the inner basin and the bottom surface of the outer basin can be filled with soil to achieve a buffering effect.

[0011] The beneficial effects of the present invention are as follows: when used in the present application, the outer pot can be used alone as a planting pot and can effectively prevent the roots from extending out of the planting pot through the water absorption holes. At the same time, after assembling the inner pot, the roots can grow within an effective range without sticking to the outer wall, while not affecting the roots' absorption of water and fertilizer, which is conducive to the implementation of subsequent stress experiments such as drought or high temperature.

[0018] Large root system experimental materials seedling planting pots, such as Figure 1 and Figure 2 It includes an outer basin 1 and an inner basin 2 with an upward opening and the same shape. The outer basin 1 has a water absorption hole on its bottom and a 300-mesh metal grid on its bottom. The inner basin 2 has a 300-mesh metal grid on its side and bottom. The inner basin 2 is detachably fixedly connected to the outer basin 1 through a connector.

[0019] When the present application is in use, the inner pot 2 is placed in the outer pot 1, and the premixed soil or matrix vermiculite is mixed and evenly placed in the inner pot 2 and in the gap between the inner pot 2 and the outer pot 1. A small hole is inserted in the soil in the inner pot 2, and seeds are placed. The seeds are placed at a depth of 1cm-2cm, and the soil is lightly covered. The seeds are placed on a tray and placed in a culture room for growth. Since the inner pot 2 is a 300-mesh metal grid, the roots can grow within an effective range without sticking to the outer wall, and at the same time, the roots' absorption of water and fertilizer is not affected, which is conducive to the subsequent drought or high temperature stress experiments.

[0020] The outer pot 1 is covered with a shading layer along its side. The shading layer can prevent sunlight from entering the outer pot 1, and can effectively prevent the water in the soil in the outer pot 1 from evaporating.

[0021] The bottom surface of the outer pot 1 is fixedly connected with a bottom plate 3 of a metal mesh, wherein the metal mesh is a 300-mesh grid, and the edge of the bottom plate 3 is in contact with and fixedly connected to the inner wall of the outer pot 1. The bottom plate 3 can ensure that when the inner pot 2 is not placed, the outer pot 1 can be used as an ordinary planting pot and can effectively prevent the roots from extending out of the planting pot through the water absorption holes.

[0022] The connecting member includes a hollow column 4 and a plug rod 5. The hollow column 4 is vertically connected to the inner wall of the bottom surface of the outer basin 1. The columns are distributed around the inner wall of the bottom surface of the outer basin 1. The plug rods 5 are respectively inserted into the corresponding columns and the upper ends of the plug rods 5 are fixedly connected to the bottom surface of the inner basin 2. The plug rod 5 is inserted into the hollow column 4, so that the inner basin 2 can be confined in the outer basin 1 and the inner basin 2 can be separated from the outer basin 1 by pulling upward. At the same time, the distance between the inner basin 2 and the outer basin 1 is the height of the hollow column 4, so that the bottom surface of the inner basin 2 and the bottom surface of the outer basin 1 can be filled with soil to achieve a buffering effect.

[0023] In the use of the present application, the outer pot 1 can be used as a planting pot alone and can effectively prevent the roots from extending out of the planting pot through the water absorption holes. At the same time, after assembling the inner pot 2, the roots can grow within an effective range without sticking to the outer wall, and at the same time will not affect the root absorption of water and fertilizer, which is conducive to the subsequent drought or high temperature stress experiments.
