Description

Technical Field

[0001] The utility model relates to the technical field of plant root system research, in particular to a soil root layer root system distribution observation device. Background Art

[0002] Plant roots are one of their nutritional organs and the primary means of obtaining the water and nutrients necessary for growth and development. Root growth directly influences the growth of the aboveground plant. The distribution of plant roots in soil layers is typically related to soil moisture, soil type, soil fertility, and crop species. Soil moisture is the primary factor influencing root growth and distribution. High soil moisture slows root growth and accelerates aboveground growth, while low soil moisture encourages root growth to absorb sufficient water for plant growth and development, as well as transpiration.

[0003] Different soil types and soil fertility may directly limit root growth. For example, sandy loam has high aeration and rapid nutrient loss. To obtain sufficient water, inorganic salts, and soluble small-molecule organic matter, plant roots grow faster and spread more widely. In addition, crop species are also an important factor limiting the growth and distribution of root systems. Different crop root types have different distributions in the soil root layer. Therefore, understanding the distribution of crop roots in the soil layer under different soil moisture content, soil type, soil fertility, and crop species can effectively guide agricultural irrigation and fertilization management during crop production.

[0004] Currently, there are few research tools for analyzing the relationship between plant root distribution and soil moisture and soil fertility in different soil types. In addition, deep soil root observation is extremely inconvenient, root measurement is time-consuming and labor-intensive, and the collected roots are easily damaged, resulting in large deviations in the data.

[0028] In this embodiment, the outer drainage bucket 100 and the outer base 300 are both made of black light-shielding material, and the inner plastic cultivation bucket 200 and the filter bottom plate 203 are both made of high-transparency plastic material. The inner plastic cultivation bucket 200 is made of high-transparency plastic material and can be taken out at any time to observe the growth of the root system. The outer drainage bucket 100 and the outer base 300 are made of black light-shielding material to simulate the soil environment and prevent the roots from being exposed to light.

[0029] In this embodiment, a holder 205 is fixedly provided on both sides of the outer wall of the semi-circular barrel body I 201, and a through groove 206 is opened on the holder 205. A base 207 that can be inserted into the through groove 206 is fixedly provided on both sides of the outer wall of the semi-circular barrel body II 202, and an elastic hook 208 is fixedly provided on the base 207. The elastic hook 208 passes through the through groove 206 and is clamped on the holder 205. The connection between the semi-circular barrel body I 201 and the semi-circular barrel body II 202 is achieved through the holder 205, the through groove 206, the base 207 and the elastic hook 208. The semi-circular barrel body II 202 can be separated from the semi-circular barrel body I 201, and the complete root system in the soil layer can be taken out without damage, thereby preventing the root system from being easily damaged and causing large deviations in the data.

[0030] In this embodiment, the tops of the semi-circular barrel body I 201 and the semi-circular barrel body II 202 are fixedly provided with edges 209.

[0034] How to use and working principle of this device:

[0035] When the device is in use, the elastic hook 208 is first passed through the through slot 206 and engaged with the holder 205, thereby connecting the semi-circular barrel body I and the semi-circular barrel body II 202. The semi-circular barrel body I and the semi-circular barrel body II 202 form an inner plastic cultivation barrel 200. In the inner plastic cultivation barrel 200, the corresponding root layer soil is added step by step according to the position of the protrusion 211 according to the collected soil, and the soil layer depth and the corresponding crops are planted. Then, the inner plastic cultivation barrel 200 is inserted into the outer drainage barrel 100, and the inner plastic cultivation barrel 200 is supported on the outer drainage barrel 100 by the edge 209. The outer drainage barrel 100 is made of black light-shielding material to prevent the roots from being exposed to light. The roots grow in darkness, simulating the soil environment.

[0036] During the growth of crop roots, the inner plastic cultivation barrel 200 can be directly drawn out of the outer drainage barrel 100, and the root growth and distribution of the crop throughout its growth period can be observed at any time, which is very convenient.
