Method.
Background technique
Seed priming techniques are that the biological mechanism sprouted based on seed is proposed, it is therefore an objective to promote seed to sprout, and
It improves the coefficient of stabilization of sprout time and sprouts neat rate, reduce the standard deviation of sprout time, improve the resistance and quality, improvement of seedling
Nutrition condition.Cause and is mainly achieved the goal by osmotic adjustment, temperature adjusting, gas regulation and hormone control etc..Seed draws
Sending out chemical substance common is polyethylene glycol (PEG), and PEG is a kind of high molecular polymer, and chemical stability is high, is not through cell
Wall, because of the biochemical reaction without influencing cell, the degree and state that PEG solution is absorbed water by colloid osmotic potential come regulating cell,
The water suction of seed can be made to tend towards stability and synchronize, it is final to improve germination rate and neat rate, cause effectively than adopting to be soaked in water
It is more.
Germination regularity is to influence a very important factor of crop groups growth, related induction crop seed
Initiation has many patent reports at home, and Chinese patent literature CN201510074856.8 discloses a kind of corn seed initiator
And its application method, each group distribution ratio are as follows: polyethylene glycol 15% ~ 35%, fulvic acid 0.5% ~ 3%, 6- benzamido group adenine
0.005% ~ 0.05%, fungicide 1% ~ 3%, surplus are water.After impregnating 12h according to kind of medicine ratio 1:2 with the initiator of this component configuration
35 DEG C are dried to original weight, have after initiation to corn seed and cause effect well.But the initiator is suitable for corn
The initiator of seed, it is not applicable to wheat seed.
Chinese patent literature CN201210460910.9 discloses the sorghum seeds initiator under a kind of Saline Alkali Stress, each group
Divide and be made according to the following ratio, carrier is distilled water: SA (salicylic acid) 5 ~ 8ppm, PGE (polyethylene glycol) 800 ~ 1000ppm, GA4
(gibberellin) 10 ~ 22ppm, 100 ~ 120ppm of ethephon (CEPHA),2-(chloroethyl) phosphonic acid, 80 ~ 100ppm of carbendazim.The initiator is only applicable under Saline Alkali Stress
Sorghum seeds, be not suitable for the crop seed of other soil properties.
Gamma-polyglutamic acid is a kind of anion abnormity peptide, its basic framework is the straight chain being formed by connecting by γ-amido bond
Molecule, there are a large amount of hydrogen bonds between chain, therefore have water-soluble and water-retaining property well.Gamma-polyglutamic acid also has pole simultaneously
