Abstract

The invention discloses a pot culture device convenient for observing the succession of plant root forms and the dynamic development at any time, which is convenient for researching the plant root ecology, wherein the soil is non-transparent, and the observation of the succession of the plant root forms in the seedling stage and the dynamic development of the plant in the soil can be realized at any time through soilless culture, but the soilless environment and the soil environment have essential difference to the plant seedling stage.

Description

Potted plant device convenient for observing plant root form succession and development dynamics at any time

Technical Field

The invention relates to a pot culture device, in particular to a pot culture device which is convenient for observing the succession of the root morphology and the development dynamic state of a plant at any time and is convenient for researching the root ecology of the plant.

Background

The root is the most important tissue part of plant ecology and is closely related to the production and development of plants, and the relationship between the plant root and various environmental factors has great fundamental theoretical research and production practice significance. The plant roots are in the soil environment, and various microorganisms such as rhizobia, endophytes, rhizosphere probiotics, pathogenic bacteria, inhibitory bacteria and protozoa, animals such as various insects and earthworms and the like may exist in the soil, and the plant roots may be influenced by other chemical factors. The plant roots interact with complex biological factors and soil physicochemical factors of the soil micro environment, and the dynamic research on the ecological relationship of the plant roots at present lacks an intuitive technology at any time. The ecological research of the plant root, such as the symbiotic nodulation of the root of the bean crop and rhizobia, is difficult to intuitively research the root form succession and the development dynamic state at any time for the size, the implantation part, the shape, the color, the infection condition by mold, the implantation quantity, the rhizobia life, the change condition of the rhizobia along with the environment and the like of the rhizobia, such as the inoculation of antibiotics, probiotics, endophytes, attached bacteria, pathogenic bacteria, inhibiting bacteria, nitrogen fertilizer, potassium fertilizer, phosphate fertilizer and the like on the plant root.

Many crop roots are typically less than 8 mm in diameter and many crop seeds are typically less than 16 mm wide.

The soil is opaque, how plant root ecology in the soil directly observes plant root forms such as crops?, vegetables and pasture can be realized by digging up the plants, cleaning the root soil and directly observing the instant forms, and the form succession and development dynamics before and after are difficult to observe at any time.

The prior art is not enough: the soilless culture roots can be directly observed at any time, but the environment without soil is completely different from the environment with soil for the plant roots; ordinary potted plants or field planting can study the root morphology of plants at a certain time point by digging soil and washing the roots, but it is difficult to study root dynamics. The prior art can not realize the instant, nondestructive, visual and visible root form of the plants in the soil in the seedling stage.

Disclosure of Invention

The purpose of the invention is: in order to overcome the defects in the prior art, the invention provides the pot culture device which is convenient for observing the succession of the root morphology and the development dynamic state of the plants at any time, and the pot culture device is used for the seedling-stage root ecological research of the plants, particularly crops, flowers, vegetables, pasture and the like.

The technical scheme adopted by the invention for solving the technical problems is as follows: a pot culture device convenient for observing the form succession and development dynamics of plant roots at any time comprises a resin box (1), a groove (2) and a double-layer glass plate (3), wherein the resin box (1) is in a cuboid shape, the resin material is made, the middle of the groove (2) is provided with 3 opaque materials at intervals of 20 cm, the double-layer glass plate (3) can be inserted into the groove (2), the double-layer glass plate (3) is formed by welding two layers of rectangular flat transparent glass side surfaces, the upper part and the lower part of the double-layer glass plate (3) are not sealed, a wide opening (4) is arranged at the upper part, bottom holes (5) are respectively arranged at the two end side surfaces of the bottom, the distance between the two layers of glass inner planes of the double-layer glass plate (3) is 8 mm, steel rods (6) can be inserted into the bottom holes (5), the steel rods (6) are made of a hard straight metal plating anti-rust layer, and the length, the width of the steel drill is shorter than that of the groove (2), the steel drill (6) is inserted into the bottom hole (5), and the double-layer glass plate (3) is filled with soil.

The names and uses of the components are:

the resin box (1) is used for supporting and stabilizing;

the groove (2) is used for fixing and isolating light;

the double-layer glass plate (3) is used for limiting the root to a plane;

the wide mouth (4) is used for facilitating soil irrigation and seeding;

the bottom hole (5) is used for stabilizing the steel chisel (6);

the steel chisel (6) is used for stabilizing soil.

The upper opening and the lower opening of the double-layer glass plate (3) are convenient to clean and reuse, the side face seal is used for keeping the distance between the two pieces of glass and a stable structure, the glass is transparent glass and used for observing the shape of the root, and the groove (2) is made of opaque materials and used for blocking light rays in the growth period.

The invention has the beneficial effects that: the method can provide the soil environment for the roots of the plants in the seedling stage, is convenient to observe the morphological succession and the development dynamics of the roots of the plants at any time, and is used for the ecological research on the roots of the plants in the seedling stage, in particular to the roots of crops, flowers, vegetables, pasture and the like in the seedling stage.
