Abstract
The present invention discloses a kind of seed accelerating germination method of sago cycas, comprises the following steps：Seed immersion, presprouting of seeds and temperature treatment.Using the method for the present invention, the germination percentage that can effectively improve Cycas seed and the germination cycle for shortening seed, so as to reduce planting cost, the utilization rate in soil is improved, the method that the present invention is provided, environmental protection, does not cause any harm to environment.
Description
Technical field
The present invention relates to forest field of planting, and in particular to a kind of seed accelerating germination method of sago cycas.
Background technology
Sago cycas is commonly called as：Sago cycas, another name：Ward off fiery any of several broadleaf plants, cycad, phoenix tail pine, phoenix-tail fern, Cycadaceae, Cycas.One say be because
Its Wood density is big, enters water and sinks, heavy such as iron and gain the name；Another say because of a large amount of ferro elements of its growth needs, so name it.Again
Name cycad, inflammable any of several broadleaf plants, phoenix tail pine, are planted in south more, are now distributed widely in China, Japan, Philippine and Indonesia
In country.It is which is bloomed that sago cycas is the most famous, is referred to as " seldom seen ", and sago cycas is graceful ornamental tree species, cultivates pole
For universal, starch-containing in stem, can be edible；Seed oil-containing and abundant starch, micro- poisonous, edible and medicinal, control dysentery,
Cough-relieving and the effect of hemostasis.Using the modes of reproduction that sows more than sago cycas, but the germination percentage of seed is low, and the cycle of germinateing is long,
The planting cost that improve sago cycas for connecing, is therefore badly in need of a kind of method for improving Cycas seed germination percentage and shortening the germination cycle.
Content of the invention
In order to solve the above problems, the invention provides a kind of vernalization mode of Cycas seed.
The present invention specifically employs the following technical solutions realization.
A kind of seed accelerating germination method of sago cycas, it is characterised in that comprise the following steps：
（1）Seed soaks：After Cycas seed is removed the peel, be put in soak soak 20-24 hour after take out, wherein soak by
The group of following weight portion is grouped into:Gibberellin 10-11 part, volume fraction are 50% sodium bicarbonate solution 150-200 part, carrot
Extract 10-15 part, zinc sulfate 4-6 part;Gibberellin can induce seed to produce protease, make the protein quilt of storage in seed
The albumen of solubility is hydrolyzed to, can be preferably used for seed sprouting, but too high or too low GA content is all unfavorable for
The Induction Process of seed, I test proves that, in the soak provided in the present invention, GA content is most beneficial for seed
Protease is produced, wherein in this soak, the trace element that carrot extractive juice can be for needed for seed sprouts offer, zinc ion
It is the activated centre of protease, zinc sulfate can improve the activity of seed endoproteinase；
（2）Presprouting of seeds：The river sand volume fraction for crossing 2mm mesh is that 10% sodium chloride solution soaks 2 hours, afterwards with clearly
Water cleans river sand, by the seed after immersion and river sand according to 1:The volume ratio mixing of 4-5, being put in 5L beaker carries out lamination
Vernalization；During vernalization, every 4-6 days in beaker spray 100-120g nutrient solution A, continue 2 months, afterwards every 10 days to
In beaker, sprinkling nutrient solution B, wherein nutrient solution A are grouped into by the group of following weight portion：Gibberellin 6-7 part, volume fraction are 50%
Sodium bicarbonate solution 100-120 part, spirulina extract 10-12 part, magnesium sulfate 1-2 part；Nutrient solution B is by following weight portion
Group is grouped into：Heteroauxin 1-2 part, colchicine 6-8 part, egg 10-15 part, spirulina extract 15-20 part, water 150-
200 parts；Seed is sprouting early stage, and main consumption is the internal nutriment that preserves, and therefore early stage nutrient solution is still mainly
The activity of enzyme in seed is improved, seed sprouts the later stage, need substantial amounts of nutriment to be used for sprouting, therefore in later stage nutrient solution
Containing the substantial amounts of small molecule carbohydrate for being easy to neutron absorption, protide, amino acids nutriment in B, and with the addition of indoles second
Acid, can induce seed fast germination；
（3）Temperature treatment：During vernalization, the first two months, the environment temperature for keeping presprouting of seeds is 15-17 DEG C, makes environment afterwards
Temperature is 25-28 DEG C；Because the Cycas seed germination cycle is longer, it usually needs 5 months or so time, therefore germination early stage needs
Glycolytic cycle and mitochondria activity in control seed body, relatively low temperature are conducive to reasonable profit of the seed to nutriment
With so as to synthesis is germinateed the later stage to the useful material that germinates, and additionally can add nutriment, now need higher temperature, profit
In absorption of the seed to nutriment so as to quickly germinate.
Above-mentioned steps（1）In, river sand is placed in ventilation and distributes moisture after over cleaning, finally makes its water content for 10-
20%.
Beneficial effect：A kind of Cycas seed vernalization mode that the present invention is provided, can cause the germination percentage of Cycas seed than often
Rule method is higher by 15% or so, makes the germination cycle time 20 days or so of seed, can effectively reduce production cost, improves soil
The utilization rate on ground.
