Abstract
The present invention belongs to a method for promoting plant seed germination and seedling growth. The seeds are placed under the electrets, the electrostatic field generated by the electrets is utilized to treat the seeds, an external power supply and a high-voltage electrostatic device are not needed, the germination rate, the germination vigor and the plant height of seedlings of the plants can be improved, and the method is simple and easy to implement, saves energy, is safe and has no environmental pollution.
Description
This invention relate to a kind of simple, energy-conservation, safe, pollution-free, promote the new method of plant seed germination and growth of seedling especially to promote plant seed germination and growth of seedlings with regard to the electrostatic field that available electret self produces effectively without external power supply.
At present, be well known that the high-voltage electrostatic field that utilizes external power supply to form promotes plant seed germination and growth of seedlings, and not external power supply of no use, the electrostatic field that only utilizes electret self to produce promotes the sprouting and the growth of seedlings of plant seed.Owing to without external power supply and high voltage electrostatic device, only just can promote plant seed germination and growth of seedlings, make that the processing of seed is simple with electret.Because without external power supply, consume electric power does not only utilize the slight electrostatic field that produces of electret just can promote plant seed germination and growth of seedlings, makes the processing of seed save the energy.In addition, when utilizing the high voltage electrostatic device of external power supply that seed is handled, not only pollute the environment because of producing ozone, and because electrion and electromagnetic radiation entail dangers to seed treatment operator's safety, so must take safety prevention measure to high voltage electrostatic device and working environment.And utilize electret to handle plant seed, because of not producing ozone, not producing electrion, electromagnetic-radiation-free,, the operator there is not harm, environmentally safe so utilize electret to handle plant seed.
The purpose of this invention is to provide a kind of new method that a kind of electrostatic field that utilizes electret self to produce is handled plant seed, it can not only improve the plant height of germination rate, germination vigor and the seedling of plant seed, and simple, save the energy, safe, pollution-free, so be particularly suitable for vast farmers prior to seeding to the processing of various crop seeds.
The present invention is achieved in that on flat board or in the flat open-top receptacle, keeps flat pending plant seed on it or wherein, with the electret that certain electric-field intensity is arranged behind the electret be placed on abreast plant seed above.All pending plant seeds all should be in the horizontal plane of electret.Keep certain distance or do not have distance between position that electret is placed and the pending plant seed.Electret continued to place certain hour, as 2-10 hour.Or certain interval of time removes electret again after repeatedly placing, and then plant seed sprouted.
Because the electrostatic field of electret has the spread effect of promotion to the sprouting of plant seed, so the plant seed after electret is handled, the plant height of its germination rate, germination vigor and seedling thereof all is higher than the seed of handling without electret.Owing to taked such scheme, make and impel plant seed germination and growth of seedling to be achieved, and make it simple, the saving energy, safe, pollution-free.
The present invention is further described below in conjunction with embodiment.
In two glass culture dishs of φ 100mm for example, put into the some grains of identical wheat seed, for example 100.Electret is that the double stretching polypropylene film makes behind the high-pressure electrostatic electret, and its electric-field intensity is 10～20kv/cm scope.With electret continuously apart from lie in above the wheat seed of one of them culture dish, the seed of this culture dish as experimental group.Not putting into electret above the wheat seed of another culture dish organizes in contrast.Electret continues to place under 15～25 ℃ room temperature environment, and be 4-5 hour standing time, removes electret then.The wheat seed of experimental group and control group is sprouted when the same terms.After 6 days, can draw whole test results of germination rate, germination vigor, germination index and the average plant height of seedling of two groups of wheat seeds, its data are as shown in table 1.
Table 1
| Germination rate (GR) % ※Germination vigor % ※※Germination index ※※※The average plant height of seedling (cm) ※※※※ | |
| Experimental group | ????91???????????91??????????30.33???????????9.14 |
| Control group | ????79???????????77??????????26.33???????????7.28 |
Total germinative number of ※ and the percentage (in 3 days) that supplies to plant experimentally subnumber
※ ※ put behind the culture dish 2 days germinative number with for the percentage (in 2 days) of planting experimentally subnumber.
※ ※ ※ germinative number and germination fate they (in 3 days).
※ ※ ※ ※ is to germinate 6 days.
Can calculate the average plant height comparison of germination rate, germination vigor, germination index and the seedling of experimental group by table 1 data you can well imagine high 15.2%, 18.2%, 15.2%, 25.5% according to component.
Claims (1)
- A kind of method that promotes plant seed and growth of seedling with electrostatic means, it is characterized in that: pending plant seed is lain in upward dull and stereotyped or the uncovered Flat bottom container, to behind the electret certain electric-field intensity be arranged, as the electret of 10-20kv/cm under 15-25 ℃ room temperature, be placed on abreast plant seed above, plant seed is positioned at the horizontal plane of electret, do not have distance between electret and the seed or keep certain distance, electret standing time is 2-10 hour, or repeatedly place every a period of time, remove electret then plant seed is sprouted.
