Method and system for breeding plant seedlings under compound induction of magnetic field and electric field

Abstract

The invention relates to a method and system for breeding plant seedlings under compound induction of a magnetic field and an electric field. The method comprises the following steps of: keeping a seedling bed at appropriate humiture, and applying an electric field 50-100KV and a magnetic field 500-4,000 gauss to seeds on the seedling bed for 10-60 minutes respectively; and when seedlings are 0-35 millimeters in height, applying an electric field 25-50KV and a magnetic field 500-4,000 gauss for 1-5 times respectively, every time for 5-30 minutes. Through experiments, magnetic and electric field induction parameters suitable for different plant seedlings are obtained. In the system, a heating tape is laid at the bottom of the seedling bed; a coil and a metal net or plate are arranged in a substrate on the seedling bed; seeds are spread on the substrate; another metal net or plate is arranged above a surface substrate; a metal meshed plate is connected with a direct current power supply generating electric field; the coil is connected with an alternating current power supply generating magnetic field; an intelligent control center is arranged; and a central processor is used for controlling the intensities of the magnetic and electric fields and the humiture of the seedling bed according to a command of a host. Due to the adoption of compound induction of the magnetic field and the electric field, the rate of emergence is high, the germinative force is good, the seedlings grow vigorously, the cultivating period is short, and the transplanting survival rate is high.

Description

(1) Technical field [0001] The invention relates to the technical field of physically induced breeding of plant seedlings, in particular to a breeding method and breeding system for plant seedlings induced by magnetic and electric fields. (2) Background technology [0002] When using seeds to breed seedlings, the screening and pretreatment of seeds have a direct impact on their germination and growth. In recent years, the technology of using light, electricity, magnetism and other physical means to pretreat seeds is being paid attention to and applied. [0003] At present, there are more and more reports on the use of magnetic or electric fields to pretreat seeds such as grains, vegetables, and fruits, and then directly sow and cultivate them. The common advantage is that it overcomes the pollution and residual hazards caused by chemical induction, can stimulate the activity of seed enzymes, increase the germination rate and germination potential of seeds, enhance the abili...

AI Technical Summary

Problems solved by technology

If tissue culture is used for the breeding of these medicinal plants, the production cost is too high; if the division is used for propagation, it is difficult to collect the provenance; if the cuttings are used for propagation, the seedling rate is low, and these breeding methods have a long production cycle, difficult management and mixed seedlings. Uneven, the actual production problem has not been solved, so the use of seed breeding is an inevitable choice

However, precious medicinal plants often have expensive seeds, long physiological dormancy period, poor germination potential, low seedling rate, and poor natural reproductive ability.
