Abstract
The present invention is the preparation process of plant growth regulator capable of promoting crop's growth and raise crop's yield. The preparation process includes dissolving organic acid or acid anhydride in water of 50-500 times via stirring, dissolving chitosan in the same amount as the organic acid or acid anhydride via stirring at 15-55 deg.c, dissolving urea and potassium dihydrogen phosphate in 0.2-0.5 time chitosan weight, adding ethanol in 30-50 times the chitosan weight and adding small amount of levulose acid. The plant growth regulator is easily to be absorbed by plant to promote plant growth via activating plant cell, raising plant resistance and raising plant immunity.
Description
Technical field
The present invention relates to a kind ofly can promote crop growth, improve the preparation method of the plant-growth regulator of crop yield.
Background technology
The twentieth century later stage it is found that in the plant materials defensive avionics system that some oligose with special construction can activated plant, kills disease and pest.Its mechanism of action is: the oligose activator sends the defendance signal after passing cell walls and plasmic film, then shift and be translated into complicated bioprocess with signal, the self-defence group of activation plant, produce Glycosylase such as β-glucolase on the one hand, chitinase, the galacturonic acid enzyme, decompose the pathogenic agent that contains activator, on the other hand, activate several energy and generate simple organism such as flavones, terpenol, the biological enzyme of compounds such as alkynes class, these compounds also can both be killed pathogenic agent, because these compounds result from plant itself, can degrade at nature, free from environmental pollution.
Introduce oligose by the external world, also can play this effect.People are with the chitosan oligomer introduced plant body of one of oligose, find its energy activated plant defensive avionics system, improve immunizing power, prevention and elimination of disease and pests is grown up strong and sturdy plant, significantly improves output and the quality of crop, its dilute solution not only can directly be sprayed on the plant, but also can handle plant seed, even handle soil, all can reach satisfied effect.
Japanese Patent (special 63-297305) adopts soluble chitin and rare organic acid or inorganic acid reaction to form chitin salt, is neutralized to neutral effective ingredient as conditioning agent with alkali then and is made into conditioning agent.The using method of this conditioning agent is very simple, at first utilize the solution of the water-soluble 1-10% of being mixed with of effective ingredient (weight) of the above-mentioned conditioning agent that makes, employing is to the method for crop seed soaking or crop foliage-spray, be applied on the farm crop, can reach the purpose that promotes plant growth, improves crop yield.The range of application of above-mentioned conditioning agent is more limited, and is little to the crop yield increase rate.
Chinese patent application discloses a kind of oligose plant growth regulator and preparation method thereof (98112868.8), exists sphere of action limited equally, can not play obvious effect to crop yield.
Summary of the invention
It is easy to the purpose of this invention is to provide a kind of preparation, can be widely used in the plant-growth regulator of increasing crop yields such as food crop, vegetables, fruit.
Preparation method of the present invention is as follows:
Organic acid or acid anhydrides are dissolved in its weight 50-500 water doubly, stir down in the chitosan of 15-55 ℃ of adding and organic acid or acid anhydrides equivalent, add respectively after the stirring and dissolving and be equivalent to urea and the potassium primary phosphate that chitosan 0.2-0.5 doubly measures, after treating the solution clarification, the ethanol that interpolation chitosan 30-50 doubly measures and a spot of left saccharic acid or Whitfield's ointment get final product, and described amount is a weight.
Described organic acid can be one of formic acid, acetate, propionic acid, citric acid, phenylformic acid, lactic acid, oxysuccinic acid, maleic acid, Whitfield's ointment or its mixing acid, organic acid anhydride is one of diacetyl oxide, propionic anhydride, MALEIC ANHYDRIDE or its mixing, also can be the mixing acid of acid and acid anhydrides.
Used chitosan is chitosan oligomer preferably, and its molecular weight is 800-2000.Molecular weight is too big or too little, and the plant-growth regulator activity for preparing is all not good, and described activity is meant and promotes growth, raising output, resistance against diseases.
Left side saccharic acid or Whitfield's ointment are activator, when it exists, can significantly improve the activity of plant-growth regulator, and the 0.1-0.2% that its add-on accounts for total amount is advisable.
Advantage of the present invention:
1, the plant-growth regulator that uses the present invention to make has the effect that tangible promotion plant-growth improves output, it can activate vegetable cell, improve the plant self-defense capability, easily by plant absorbing, can improve via plant immunity, significantly strengthen resistant effect, obviously improve grain, fruits and vegetables equal yield line and quality.
2, the raw material chitosan oligomer is a natural product, is easy to get, and is without any side effects.
3, production technique is easy, is easy to suitability for industrialized production.
4, the plant-growth regulator of the present invention's preparation is widely used, and is applicable to various food crop, and vegetables, fruit-bearing forest and various flowers promptly can be used for field crop, are specially adapted to booth and various protections field crop again; Conditioning agent can be handled seed with infusion method, can dilute direct sprinkling plant leaf surface, also can irritate root, also can be in order to handle soil.
Embodiment
The present invention will be further described below in conjunction with embodiment.
Embodiment 1:
1.0g acetate is dissolved in the 500ml water, stir is the chitosan oligomer of 6 (molecular weight is about 1200) in 40 ℃ of adding 1.0g polymerization degree down, stir 30min, add 0.4g urea and 0.3g potassium primary phosphate, continue to be stirred to the solution clarification, add 40ml ethanol and 0.8g Whitfield's ointment, can make about 550ml plant-growth regulator original solution.
Embodiment 2:
Identical with embodiment 1, only do not add Whitfield's ointment.
Embodiment 3:
0.7g MALEIC ANHYDRIDE and 0.3 oxysuccinic acid are dissolved in the 200ml water, stir is the chitosan oligomer of 6 (molecular weight is about 1200) in 40 ℃ of adding 1.0g polymerization degree down, stir 30min, add 0.4g urea and 0.3g potassium primary phosphate, continue to be stirred to the solution clarification, add 30ml ethanol and 0.8g left side saccharic acid, can make about 230ml plant-growth regulator original solution.
