Description
Technical Field
The utility model belongs to the field of plant cytogenetics, in particular to a double-layer pot plant device for acquiring a large number of plant root tips for a plurality of times.
Background
In plant cytology research and distant hybridization breeding, the chromosome number and chromosome composition of plant cells are often identified, and the root tip is a common material for identifying the chromosome number and chromosome composition of plant cells. At present, there are two main methods for obtaining plant root tips: (1) the method for germinating and rooting seeds is simple and feasible, but requires a large amount of materials and a sufficient number of seeds. (2) A method for taking roots from plants mainly aims at materials with small seed quantity or vegetative propagation materials, and three methods are provided for taking roots from plants: (a) the water culture root-taking method needs to control the temperature, the moisture, the nutrients and the like, if the control is improper, the root rot is easy to cause, and in addition, the chromosome splitting phase state of a water culture plant is not as good as the phase state of soil culture; (b) the method for cutting soil and taking roots in field planting has the advantages that the root taking direction of field plants is not clear due to the fact that soil is not transparent, the complete plant root system cannot be obtained, conditions such as temperature, illumination, moisture and nutrients in fields are not easy to control, the growth state of roots is difficult to control, and the method for taking roots is time-consuming, labor-consuming and poor in effect; (c) the method is easy to control the conditions of temperature, illumination, moisture, nutrients and the like, but the root of the plant needs to be taken out of the pot when the root is taken by the method, most of the root of the plant is interweaved together in an intricate and complex manner and is adhered to the soil together in the growth process of the plant, and the plant is extremely difficult to take out because the soil is partially adhered in the flowerpot; secondly, because the plants are taken out of the pot without medium, if the roots of the plants are too long, the plants can be wound on the bottom of the pot, the plants are taken out forcibly, the attached soil is easy to collapse, and the whole root system can be damaged inevitably, so that the growth of the plants is adversely affected; in addition, the soil in the flowerpot is relatively loose, a certain soil form needs to be maintained by the flowerpot, if a plant is forcibly taken, the soil is loose, the root structure of the plant can be damaged, and the growth and development of the plant are seriously influenced. The method for obtaining the plant root tip has the problems of time and labor waste, poor root taking effect and the like, and influences the normal growth of plants after the root is taken, thus damaging the growth and development of the plants.
In order to overcome the problems of the root taking method, a patent of a pot plant device for obtaining a large number of plant root tips for multiple times (CN206575898U) discloses a pot plant device, which is mainly characterized in that a plastic film with holes is flatly paved at the bottom of a flowerpot, the two ends of the plastic film symmetrically extend out of a flowerpot opening along the inner wall of the flowerpot, the plastic film is lifted when the roots are taken, the whole plant is taken out, and the root tips are cut around the attached soil. Although the method is improved compared with the traditional potted plant root taking method, the root taking efficiency is improved, and the plant is protected to a certain extent, if the plant is larger like a corn root system, the plant can be taken out from the flowerpot by spending more strength, and if the cultivation time is long, the soil is caked and is not easy to take out when being clamped in the flowerpot; in addition, if the culture medium is a nutrient soil or other medium, the texture is loose, which inevitably causes the falling of the medium attached to the root system, damages the fibrous root system of the plant and is not beneficial to the continuous culture of the plant.
In summary, the existing methods for obtaining plant root tips are time-consuming and labor-consuming, have poor root-taking effect, and have great damage to plants after root taking, which affects normal growth of plants, so it is necessary to find a root-taking device that can obtain a large amount of high-quality root tips for many times, and at the same time, will not damage the root systems required by normal growth of plants, so that the plants can continue to grow normally, so as to facilitate later observation and subsequent research work.
