A device for observing the growth and distribution of rice roots

Abstract

The invention discloses a device for observing the growth and distribution of rice roots, which is characterized in that it comprises: a barrel, a support frame and a plurality of mesh surfaces, the support frame is arranged in the barrel, and the mesh surfaces are installed along the height direction of the support frame. A device for observing the growth and distribution of the rice root system of the present invention can not only measure the root system morphological indicators in the process of rice growth and development, such as root fresh weight, dry weight, number, length, volume, etc., but also facilitate the observation and determination of the space of the rice root system Distribution, such as root layer distribution ratio and root length density. The whole device has ingenious design, simple structure, low production cost, simple and convenient operation, accurate and reliable results, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a device for observing the growth and distribution of plant roots, in particular to a device for observing the growth and distribution of rice roots. The invention belongs to the field of agricultural sampling equipment. Background technique [0002] Plant roots have many functions, such as absorbing and transporting nutrients and water, synthesizing plant hormones and other organic substances, storing nutrients, and supporting plants to fix them in the soil. It is the main organ for material exchange between plants and the external environment. Root morphological characteristics include root volume, geometry, length, distribution depth, root density, branching status, root weight, root surface area, number of root hairs, and number of root tips. Root morphology is closely related to the absorption capacity of nutrients and water. [0003] But the study of plant roots is much more difficult than the study of aerial parts. It...

Problems solved by technology

Existing rice root sampling methods generally include the direct digging method with tools in the field growth environment, the pre-embedded root bag method, the whole pot flushing method under pot conditions, and the direct observation method under hydroponic conditions. These methods have incomplete sampling or cannot It shows the true growth state of rice in the soil, making it difficult to completely observe and measure the true morphological structure of the rice root system
