Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention relates to the technical field of rice root system sampling and cleaning. The invention discloses a rice root system sampling method and device. The device comprises a sampling body anda striking cover; the striking cover is detachably fixed on the sampling body; a handle is arranged on the sampling body; the sampling body comprises an upper sampling part and a lower sampling part;the upper sampling part is rotatably arranged on the lower sampling part; a cutting and lifting assembly is arranged at the joint of the upper sampling part and the lower sampling part; and the cutting and lifting assembly is opened or closed through relative rotation between the upper sampling part and the lower sampling part. According to the device, the cutting and lifting assembly is arrangedat the joint of the upper sampling part and the lower sampling part and can be used for cutting off and separating a to-be-sampled soil body from a lower soil body, so that the integrity of the sampled soil body can be facilitated when the sampler is pulled out. Besides, the sampling auxiliary pipe is arranged in the upper sampling part, so that the use is more flexible, the sampler cannot be occupied for a long time, and the experiment process is accelerated.

Description

technical field [0001] The invention relates to the technical field of rice root system sampling and cleaning, in particular to a rice root system sampling method and a sampling device. Background technique [0002] The root system is the main organ for plants to absorb nutrients and water, and is the basis for the survival of the above-ground parts. Plant roots are deep underground, and observation and research are difficult. Therefore, reasonable root extraction devices and research methods are particularly important for studying root systems in the field. Currently, although there have been many installations on root sampling and how to observe roots, most of them focus on off-field conditions. The plant root system has strong plasticity, and its shape and function are completely different in different growth media (such as agar, hydroponics, etc.), so the study of root system under field conditions is more in line with the actual growth status of plants. [0003] At pr...
