Abstract
The invention discloses a kind of raising bare slope revegetation method of molasses grass germination percentage, it is related to field of planting.This method comprises the following steps：1. intermittent warming, the seed of molasses grass is soaked in distilled water, is stored 57 days with 4 DEG C of temperature lucifuge, and storage time, which reaches, takes out seed after 57 days and dried under 20 25 DEG C of environment of room temperature；②H2O2Handle, the seed that 1. step obtains is soaked in 30% H2O2In, lucifuge handles 0.5 1h, is cleaned seed with distilled water after the completion of processing, and dried under room temperature environment；3. PEG vernalization is handled, and the seed lucifuge that 2. step obtains is soaked in into 24h in 2 10% PEG solution, seed is cleaned with distilled water after the completion of processing, and dried under room temperature environment.The present invention effectively increases the germination percentage of wild molasses grass seed, and 13% is promoted to by 7.5%；The germination percentage of active seed is promoted to 92.86% by 53.57%；The molasses grass seeds germination percentage of commercialization by 81.25% can be promoted to 93.5%.
Description
Technical field
The present invention relates to field of planting, more particularly to a kind of side for improving bare slope revegetation molasses grass germination percentage
Method.
Background technology
Molasses grass belongs to grass family molasses grass platymiscium, originates in Africa and South America, because its extreme is drought-enduring, acidproof, often quilt
For in water and soil conservation and slope vegetation restoration engineering.Meanwhile, molasses grass is the high-quality feed of ox, is made available for herding with ensiling
With.The Forage Germplasm Resources that molasses grass is introduced for 1985 as China, are protected by the water and soil for being increasingly being applied to south China area
Hold in construction and agricultural production.At present, the cultivation of China's molasses grass relies primarily on the mode of sowing, but due to wild molasses grass seeds
Matter resource is uneven, and about 86% wild molasses grass seed is inactive, and the germination percentage under nature only has 7.5% or so.
So how to lift molasses grass percentage of seedgermination becomes a hot issue.
The method of lifting percentage of seedgermination has Physical and chemical method.Physical is to be handled by such as becoming accumulated temperature, take off kind of a skin
Processing, the powerful processing of strong acid and the physical means such as ultrasonically treated, break the physical barriers for hindering seed to sprout, so that seed
Can successfully it sprout.Chemical method is to utilize such as gibberellin, PEG, KNO3And/or H2O2The kind do not germinateed Deng chemical reagent processing
Son, is used as the chemical signal of activation germination so that the method that seed is sprouted.
The content of the invention
The purpose of the present invention is that overcome prior art to there is shortcoming and defect improves bare slope vegetation there is provided one kind
Recover the method with molasses grass germination percentage.
The object of the present invention is achieved like this：
Specifically, this method comprises the following steps：
1. intermittent warming
The seed of molasses grass is soaked in distilled water, stored 5-7 days with 4 DEG C of temperature lucifuge, storage time was reached after 5-7 days
Seed is taken out and dried under 20-25 DEG C of environment of room temperature；
②H2O2Processing
The seed that 1. step is obtained is soaked in 30% H2O2In, lucifuge processing 0.5-1h will be planted after the completion of processing with distilled water
Son is cleaned, and is dried under room temperature environment；
3. PEG vernalization is handled
The seed lucifuge that 2. step is obtained is soaked in 24h in 2-10% PEG solution, with distilled water by seed after the completion of processing
Clean, and dried under room temperature environment.
The present invention has following advantages and good effect：
1. the intermittent warming and the H of chemical method of Physical are passed through2O2With PEG vernalization processing, wild molasses grass seeds is effectively increased
The germination percentage of son, 13% is promoted to by its germination percentage by 7.5%；
2. the germination percentage for having active seed in wild molasses grass seed is promoted to 92.86% by 53.57%；
3. in addition, the method is also applied for the molasses grass seed of commercialization, can by the molasses grass seeds germination percentage of commercialization by
81.25% is promoted to 93.5%.
Embodiment
Described in detail below by embodiment：
First, embodiment 1
1st, intermittent warming
The seed of molasses grass is soaked in distilled water, stored 5-7 days with 4 DEG C of temperature lucifuge, storage time was reached after 5-7 days
Seed is taken out and dried under 20-25 DEG C of environment of room temperature；
2、H2O2Processing
The seed of step 1 is soaked in 30% H2O2In, lucifuge processing 0.5-1h is washed seed with distilled water after the completion of processing
Only, and under room temperature environment dry；
3）PEG vernalization is handled
The seed lucifuge of step 2 is soaked in 24h in 2-10% PEG solution, seed is cleaned with distilled water after the completion of processing,
And dried under room temperature environment.
Further, storage time is 7 days in step 1；Processing time in step 2 is 0.5h；PEG's is dense in step 3
Spend for 10%.
2nd, embodiment 2
1st, intermittent warming
The seed of molasses grass is soaked in distilled water, stored 5-7 days with 4 DEG C of temperature lucifuge, storage time was reached after 5-7 days
Seed is taken out and dried under 20-25 DEG C of environment of room temperature；
2、H2O2Processing
By step 1, seed be soaked in 30% H2O2In, lucifuge processing 0.5-1h is washed seed with distilled water after the completion of processing
Only, and under room temperature environment dry；
3rd, PEG vernalization is handled
By step 2, seed lucifuge be soaked in 24h in 2%-10% PEG solution, seed is washed with distilled water after the completion of processing
Only, and under room temperature environment dry；
Further, storage time is 5 days in step 1；Processing time in step 2 is 1h；PEG concentration is in step 3
7.5%。
3rd, comparative example 1
Comparative example 1 compared with Example 1, is changed to " keep away with room temperature except " storing 5-7 days with 4 DEG C of temperature lucifuge " in step 1
Light is stored 5-7 days " outside, other step all sames.
4th, comparative example 2
Comparative example 2 compared with Example 1, except in step 2 " be soaked in 30% H2O2In, lucifuge processing 0.5-1h " is changed to
" it is soaked in distilled water, lucifuge handles 0.5-1h " outside, other step all sames.

6th, control group
Control group uses the molasses grass seed without any processing.
In order to verify the percentage of seedgermination of each embodiment, now method is accompanied to measure above-mentioned 6 kinds of molasses through different disposal using paper
Grass seed germination percentage and germination index；In addition to method for treating seeds is different, remaining each condition keeps identical.
Test method：Qualitative filter paper is laid in a diameter of 9cm batch cultur ware, soaked with 5mL distilled water；Will
50 wild molasses grass seed proper alignments of each group processing are in culture dish, and the alternating temperature for being placed on 18-30 DEG C becomes light incubator
Middle culture 1 week and moisturizing in good time；Every group of processing is repeated 3 times.Germinative number was recorded at the 7th day long with the total root of seed, calculate germination
Rate and germination index；Wherein germination index has reacted the vigor of seed, and its index is higher, and seed vitality is stronger.
Result of the test such as following table.
| Handle type | Germination percentage（%） | Active percentage of seedgermination（%） | Total root is long（cm） | Germination index（GI） |
| Embodiment 1 | 13.3 | 95.0 | 11.0 | 4.4 |
| Embodiment 2 | 12.0 | 85.7 | 9.0 | 3.2 |
