Water-induction strong-root plant seedling culture device

Abstract

The invention discloses a plant seedling culture device, and particularly discloses a water-induction strong-root plant seedling culture device. The water-induction strong-root plant seedling culture device consists of a water holding tray, a net bed bracket, a plant seed holding net bed and absorbent paper, wherein the net bed bracket is placed into the water holding tray; the plant seed holding net bed is placed on the net bed bracket; the absorbent paper is spread on the net bed, the side end of the absorbent paper is in contact with the inner bottom surface of the water holding tray. By adopting the plant seedling culture device, technical support can be provided for selective culture of plant seedling materials which grow robustly, orderly and consistently in the researches of plant developmental biology, physiological plant ecology and the like.

Description

technical field [0001] The invention relates to a device for cultivating plant seedlings, in particular to a device for cultivating plant seedlings used in laboratories. Background technique [0002] In the research of plant developmental biology and plant physiological ecology, etc., it is usually necessary to select well-growing and uniform plant seedlings for experimental treatment, which can minimize the error caused by individual differences in seedling development among experimental materials, In order to ensure the authenticity and accuracy of the experimental processing effect. At present, there are several methods for preparing experimental materials by seed propagation: (1) Spread double-layer filter paper in a petri dish, place plump and uniform plant seeds evenly on the filter paper, replenish water and ventilate regularly, and Or cultivate in an incubator. After the seeds germinate and the roots and cotyledons grow sufficiently large, take out the plant seedlin...

AI Technical Summary

Problems solved by technology

In the research of plant developmental biology and plant physiological ecology, etc., when the aforementioned method (1) is used to prepare experimental materials, the roots of the plant seedlings in the petri dish are spread flat and a large number of root hairs adhere to the surface of the filter paper, and , the individual root systems of different seedlings are often interlaced, so that in the process of taking out the plant seedlings with tweezers, due to the adhesion of the filter paper to the root hairs and the interlaced friction of the individual root systems of different seedlings, a large number of root hairs of the seedlings will be damaged. In addition, due to the large curvature of the root system, when the seedlings are transplanted into the soil in the flowerpot, the root system is easily broken and the root tip is damaged. In the end, the survival rate of the plant seedlings cultivated in the flowerpot will be lower. Low and highly inconsistent future growth

Compared with the method (1), the damage to the root system of the plant seedlings in the method (2) is lower. However, since the soil in the seedling pot and the plant seedlings are taken out together for transplanting, it can only be transplanted according to the seedlings. Judging the growth status of stems and leaves on the ground Select plant seedlings with good growth and uniformity, and the development status of the plant root system cannot be seen. In the end, there are often large differences in the development of plant root systems, resulting in the growth of plant seedlings cultivated in flower pots. large variation

The (3) method has less damage to the root system of plant seedlings, and its disadvantage is mainly due to the fact that during the cultivation period, the seedlings can only be thinned according to the growth status of the stems and leaves on the seedling ground, and the plant species with good growth and uniformity can be selected. Seedlings, the development of the plant root system cannot be seen. In the end, there are often large differences in the development of the plant root system, resulting in large differences in the growth of plant seedlings cultivated in flower pots.

In addition, due to the germination of seeds in the soil, especially for wild plants, the germination rate of seeds in the soil is low and the growth of seedlings is slow in the early development stage, which often delays the test process
