Problems solved by technology

However, the soil extraction method of this device is to quickly freeze the soil in the side chamber and then slice it. The thickness of the soil slice is not easy to control, and the quick freezing process will change the nutrient status and microbial activity in the soil, and it is difficult to truly reflect the nutrients and microbial activity in the soil. The actual situation
Secondly, the root-separating net of the root box is not easy to tighten, resulting in uneven soil surface at the rhizosphere interface, which brings inconvenience to soil extraction, and the error is large
In addition, irrigation often adopts the method of irrigated from the top or through the capillary from the bottom. The difference in soil cracks in different root chambers often leads to uneven irrigation, and it is easy to change the direction of water movement, resulting in lateral migration of nutrients in the soil. test accuracy

Embodiment Construction

[0018] Figures 1 to 5 combine to provide a plant root box culture device for rhizosphere soil sampling. For ease of description, in Fig. 1 and Fig. 2, what show in the side chamber 1 on the left is the situation when the flashboard 6 is set, and what show in the side chamber 1 on the right is the situation when the flashboard 6 is not set. However, in practice, the states of setting the boards 6 in the two side chambers 1 are the same (that is, they are set at the same time or canceled at the same time).

[0019] The plant root box cultivation device used for rhizosphere soil sampling of the present invention comprises a detachable box body, and this box body consists of a middle chamber 2 and two side chambers respectively positioned at the left and right sides of the middle chamber 2. 1 composition. Therefore the centerline 4 of the square frame is the centerline of the middle chamber 2 .

[0020] Each side chamber 1 is surrounded by two side chamber side panels 11 and one...

Abstract

The invention discloses a kind of plant root box culture equipment used in rhizosphere oil sample which includes a removable block body and in the block body grip lays two pieces of root room separation mesh piece so it slips the block body into one medial cell and two side cells; at the bottom of block body sets up a guide water board with a hole on it and the locelle irrigation bottom cut locates under the guide water board and at one end of the guide water line locates in the locelle irrigation bottom cut and the other end locates in the cavity of block body through the guide water hole; the side cell sets up a inner lining board slipping in the side cell and the plug board may lay between the inner lining board and the block body and the inner lining board parallels with the center line of the plug board. Adopt the invention's equipment can sampling the different distance oil convenience and accurately.

Description

technical field [0001] The invention relates to a plant root box culture device, in particular to a plant root box culture device used for rhizosphere soil sampling. Background technique [0002] A large number of research results have proved that the rhizosphere is the most active place for soil microorganisms, and the rhizosphere soil is the part in direct contact with the plant root system; therefore, the nutrient status in the plant rhizosphere soil can better reflect the effectiveness of plants than the whole soil . Therefore, the status of nutrients and microorganisms in the rhizosphere soil has always been a research hotspot in the field of plant nutrition. In order to obtain soil samples at different distances from the root surface, various plant cultivation devices have been designed, among which the three-chamber root box cultivation device is the most commonly used. However, the soil extraction method of this device is to quickly freeze the soil in the side cham...
