Adjustable simple real-time root growth observation device

Abstract

The invention discloses an adjustable simple real-time root growth observation device. The adjustable simple real-time root growth observation device comprises a first observation plate, a second observation plate, lateral plates and a bottom plate, the first observation plate is opposite to the second observation plate, the bottom plate is arranged at the bottom between the first observation plate and the second observation plate, and the lateral plates are arranged at two sides of the part between the first observation plate and the second observation plate; a fastening device is arranged at the middle of each of two sides of each of the first observation plate and second observation plate. The adjustable simple real-time root growth observation device is easy to manufacture, low in cost, convenient to operate, visible and capable of realizing real-time observation; the plant root growth and structure can be completely observed in situ, through matching with different moisture and environment conditions, the growth comparison observation for the root in the soil can be realized after performing drought and salt damage treatments and growing under different plant hormones and light irradiation conditions.

Description

technical field [0001] The invention relates to an observation device, in particular to an adjustable and simple root growth real-time observation device. Background technique [0002] Plants grow in terrestrial ecosystems, and they absorb water and nutrients mainly through the root system to meet the needs of their own growth and development, metabolism and other physiological activities and transpiration. Plant roots have physiological functions such as fixing, supporting, absorbing, secreting, synthesizing and feeling the soil environment. As early as the beginning of the 18th century, Hales in Germany began to study the root system of plants. However, because the root system grew underground, there were certain difficulties in accurate sampling, measurement, and observation. The progress has been very slow, until the 1930s, with the growing attention of plant root development and root system research, root system research has been regarded as a very potential basic scie...

1994,6:5-9), soil drilling method, container method, etc., but there are certain shortcomings: 1) Although the whole root system of the plant can be dug out by the digging method, and the length, shape, color Such as direct observation, but it requires a lot of manpower and time. At the same time, the observation of the root system and the collection of data are not continuous. Once dug out and separated from the soil, the root system cannot be used for subsequent research; 2) Soil drilling Although the sampling method is faster, it is easy to cause errors for materials with low root densi
