Abstract
The invention discloses a kind of method for improving wild Spartina alterniflora's percentage of seedgermination.Selected wild Spartina alterniflora's seed, after sterilized sterilization, purged and packed, carries out low temperature, wet-storage；Before sowing, the seed of storage is taken out, be placed in after being pre-processed in the water-loss reducer for suctioning moisture of low temperature, in reseeing Nutrition Soil.By technical solution of the present invention, wild Spartina alterniflora's percentage of seedgermination can bring up to more than 70%, and germinate and emerge neatly, and seedling quality is high, solve the problems, such as that wild Spartina alterniflora's seed is not sprouted under normal conditions or germination rate is extremely low, be conducive to the preservation of wild Spartina alterniflora's germ plasm resource.It is applied widely, can cover the wild Spartina alterniflora at different beach, small by outside climatic Effects of Factors, and seeding and seedling raising can be carried out for the whole year.Processing procedure and the seed for the treatment of have no toxic side effect, non-environmental-pollution, to seed contactee without danger；Also have handling process simple, it is with low cost, it is easy to the features such as operation and batch processing.
Description
Technical field
The present invention relates to a kind of method for improving wild Spartina alterniflora's percentage of seedgermination.
Background technology
Spartina alterniflora has the salt tolerance and salt tolerance of height, moreover, also with it is resistance to silt bury, resistance to stormy waves, viability
Vigorous the characteristics of, as the pionner that exploitation seabeach applies.The Main Function of Spartina alterniflora includes protecting seacoast, and preventing and treating seashore is invaded
Erosion；Created land with silt, is enclosed and cultivated；Use herbage as, raise oxen and horses donkey sheep；Pollution can also be controlled, as wild animal habitat
Deng.Spartina alterniflora is main with seminal propagation, i.e., with transplanting seabeach after seed seedling-raising.But the seed contamination gathered from field is tight
Weight, and viability is easily reduced during normal storage, so as to the germination percentage for causing seed is reduced.
At present, the technology of the germination percentage of seed is improved by the pretreatment of Spartina alterniflora's seed and has no report.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided it is a kind of it is applied widely, pollution-free, easily operated, into
This is cheap, and the method that can effectively improve wild Spartina alterniflora's percentage of seedgermination.
Realize that the technical scheme of the object of the invention is to provide a kind of method for improving wild Spartina alterniflora's percentage of seedgermination, step
It is rapid as follows：
1st, whne field grown Spartina alterniflora fruit ear in yellow, it is sagging when, choose the full fruit ear of Spikelet development and collect seed；
2nd, the fruit ear threshing to gathering, roguing, screening obtains full, unabroken seed；
3rd, the seed that will be selected is inserted in gas permeability mesh bag, is rinsed with the clean water of flowing, after being filtered dry moisture, then seed is placed in
During mass concentration is 2% liquor natrii hypochloritis, sterilization is processed 15~20 minutes under stirring condition；
4th, with aseptic water washing, after suck dry moisture, it is placed at shady and cool ventilation and dries 2~4 days；
5th, seed is sub-packed in kraft paper bag, in the case where relative humidity is the airtight condition that 90~100%, temperature is 4~10 DEG C
Storage；
6th, before sowing, the seed of storage is taken out, is placed in the water-loss reducer for suctioning moisture that temperature is 1~4 DEG C and pre-processes, from the 10th
Its radicle for starting to observe seed exposes situation, every observation in 2 days once；
When the 7th, observing that the seed for having radicle to expose reaches 50~60%, the water-loss reducer aseptic water washing that will adhere to outside seed
Totally, it is seeded in Nutrition Soil.
Compared with prior art, advantage of the invention is that：
1st, the present invention is using first selected wild Spartina alterniflora's seed, then carries out the pretreatment of seed low-temperature moisture preservation and water-loss reducer treatment,
The method finally germinateed or sowed, can bring up to more than 70%, and germinate and emerge by wild Spartina alterniflora's percentage of seedgermination
Neatly, seedling quality is high, solves the problems, such as that wild Spartina alterniflora's seed is not sprouted under normal conditions or germination rate is extremely low,
Be conducive to the preservation and protection to wild Spartina alterniflora's germ plasm resource.
2nd, the method that the present invention is provided is applied widely, the wild Spartina alterniflora at different beach can be covered, by extraneous gas
Wait Effects of Factors small, nursery can be carried out for the whole year；Processing procedure and the seed non-environmental-pollution and toxic and side effect for the treatment of, to seed
Contactee is without danger.
3rd, it is simple with handling process, it is with low cost, it is easy to the features such as operation and batch processing.
Specific embodiment
Technical solution of the present invention is further described with reference to embodiment.
Embodiment 1
The present embodiment technical scheme is applied to Spartina alterniflora's seed as raw material, at the moisturizing pretreatment of seed and water-loss reducer
Reason, so as to the moisture content of the reduction of the pollution rate of seed, seed is maintained into a rational level, and then reaches raising seed hair
The purpose of bud rate, it is comprised the following steps that：
1st, wild Spartina alterniflora's seed cleaning：Whne field grown Spartina alterniflora fruit ear in yellow, it is sagging when, choose small ear hair
Full fruit ear is educated to collect seed；Through threshing, the removal of impurity, drying are gone, selected full, unabroken seed is standby；
2nd, seed low temperature, moisturizing pretreatment：Selected seed is inserted in gas permeability mesh bag, 30 points are rinsed with the running water of flowing
Clock, is filtered dry after moisture and puts into during mass concentration is 2% liquor natrii hypochloritis, and stirring is sterilized 15 minutes.Aseptic water washing 5 is used again
Time, suck dry moisture is dried 2 days as at shady and cool ventilation；Seed is divided in kraft paper bag, is stored in and is filled sterile purified water
Closed container in（Relative humidity is kept to reach 100%）, then container is placed in 4 DEG C of refrigerator to Seeds preprocess；
3rd, water-loss reducer treatment：Pretreated seed is placed in the water-loss reducer for suctioning moisture that temperature is 1~4 DEG C before sowing,
Observed whether seed has radicle to expose since the 10th day.Every observation in 2 days once, when it was observed that the seed for having 50~60% has
When radicle exposes, the water-loss reducer that will adhere to outside seed is clean with aseptic water washing, in sowing Nutrition Soil, seed is germinateed
Culture is directly sowed.
The final germination percentage of Spartina alterniflora's seed processed by technical solution of the present invention can reach more than 70%, and germinate and go out
Seedling is neat, and seedling quality is high；And it is housed in that to dry the percentage of seedgermination of ventilation be only 13.3%.
