Description
Technical field
The present invention relates to water-saving antitranspirants of a kind of plant and preparation method thereof, belong to plant water-saving agent technical field.
Background technology
With the influence of global warming and mankind's activity, water resource, which has been increasingly becoming, restricts socio-economic development
One of principal element.In China, agricultural is the basic industry of national economy, but due to distribution of water resources unevenness, and basic water conservancy is set
Backwardness is applied, agricultural irrigation efficiency of water application only has 40%.And display is investigated, DESERTIFICATION IN CHINA soil is 2,620,000 square kilometres, is
More than 2 times of national total cultivated area, and continue that expansion trend is presented.Serious ecocrisis makes water resource seem more precious,
And water resources crisis and taking place frequently for arid influence each other, and the restraining factors to agriculture and forestry and ecological environment are collectively formed.Therefore,
Efficiently imperative using water resource, modern Technology of Drought-resistant is promoted in exploitation also more seems important.That is exploitation novel plant is water-saving
Drought resistance agent improves water use efficiency prepared by crop, is the indispensable component part of China's water-saving agriculture.
The antitranspirant of commercialization is varied, for its principle, is generally divided into two kinds of metabolic pattern and film-type：Metabolism
Type antitranspirant mainly acts on plant photosynthesis metabolic pathway, and inducing gas bore closure increases stomatal resistance, to reduce plant
It is lost to the moisture in environment by transpiration.Such representative antitranspirant main component has ABA, CaCl2, yellow
Rotten acid etc..Film-type antitranspirant is sprayed by external source, is formed thin film on plant leaf blade surface, is hindered by way of gas
The drought resistance agent of the moisture loss in hole, this type has kaolin etc..Above-mentioned antitranspirant has been widely used in production practices, but
Also expose a series of problems simultaneously：If toxicity is excessive (mercuric acetate benzene), involve great expense (ABA), poorly water-soluble (fulvic acid),
Influence photosynthesis (film-type), conventional thin membranous type blade face antitranspirant block stomata, make plant suffocate and poisoning the problems such as meeting
Harm is generated to plant.In conclusion developing ecological safety, cheap, applicability is wide and acts on apparent novel anti-steaming
Agent is risen, there is very strong realistic meaning.
In conclusion developing ecological safety, cheap, applicability is wide and acts on the apparent anti-transpiration of novel microbial
Agent has urgent need.Therefore, efficiently imperative using water resource, modern Technology of Drought-resistant is promoted in exploitation also more to seem
It is important.I.e. develop novel plant saving water, resisting drought agent, improve crop prepare water use efficiency, be China's water-saving agriculture can not or
Scarce component part.
Invention content
The technical problems to be solved by the invention：Stomata is blocked for conventional thin membranous type blade face antitranspirant, plant is made to stop up
The problems such as breath and poisoning, can lead to the problem of plant and endanger, and provide a kind of water-saving antitranspirant of plant and its preparation side
Method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of water-saving antitranspirant of plant, including following weight parts raw material：
30~40 parts of n-dodecanols, 25~30 parts of positive hexadecanols, 20~25 parts of aromatic alcohols, 10~15 parts of emulsifier T-70,1000
~1200 parts of deionized waters, 3~5 parts of Ammopiptanthus mongolicus waxes, 1~2 part of drought resisting object, 2.5~3.0 parts of humic acid potassiums.
The specific preparation process of Ammopiptanthus mongolicus wax is：
（1）It is crushed after taking Ammopiptanthus mongolicus washing to air-dry, obtains Ammopiptanthus mongolicus powder；
（2）Ammopiptanthus mongolicus powder is added in ether and is transferred in mass ratio 1 after immersion treatment：The petroleum ether of 1 mixing and mixing for absolute ethyl alcohol
It closes and is extracted in liquid, obtain crude extract and filter cake；
（3）Filter cake is immersed in after being extracted in chloroform and filtrate and filtrate is collected by filtration, evaporated after filtrate is merged with crude extract
To dry, then product will be evaporated and be added in normal heptane, stand at 0~4 DEG C 20 after sealing~for 24 hours, it is collected by filtration after standing
Precipitation, obtains Ammopiptanthus mongolicus wax.
The mass ratio of the Ammopiptanthus mongolicus powder and ether is 1：2~1：4, the mass ratio of the Ammopiptanthus mongolicus powder and mixed liquor is 1：
4~1：8.
The leaching process is to extract 5~6h at 70~75 DEG C with 200~300r/min.
The mass ratio of the Ammopiptanthus mongolicus powder and chloroform is 1：2~1：4, the extraction process is to extract 5 at 50~55 DEG C
~6h.
The normal heptane dosage is the 10~20% of Ammopiptanthus mongolicus silty amount.
The drought resisting object is that be immersed in mass fraction be to be collected by filtration after ultrasonic extraction in 5% potassium hydroxide solution to filtrate
Filtered fluid, and rotary evaporation goes moisture removal to be made.
The potassium hydroxide solution dosage is 6~10 times of Ammopiptanthus mongolicus silty amount.
A kind of preparation method of the water-saving antitranspirant of plant, the specific steps are：
It takes n-dodecanol, positive hexadecanol, aromatic alcohol, emulsifier T-70 to be added in deionized water and mix, adds Ammopiptanthus mongolicus wax, resists
Non-irrigated object, humic acid potassium discharge after continuing 30~40min of stirring, obtain the water-saving antitranspirant of plant.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention utilizes wax layer combination n-dodecanol, positive hexadecanol, the aromatic alcohol of Ammopiptanthus mongolicus epidermis, because on its macromolecular chain
There are a large amount of hydrophilic radicals, by hydrogen bond action, firmly lock hydrone, increases the evaporation resistivity of moisture, spray the shape on blade face
At the molecular film of layer of transparent, the resistance to mass tranfer of moisture gas-liquid transmission is increased, antitranspirant is made to play water_air exchange energy barrier
Hinder effect, using above having very strong inhibition and water retention, sprays and quickly spontaneous can be sprawled to form one layer of densification, nothing on blade face
The transparent molecular film of color can effectively delay blade face moisture evaporation rate, inhibit moisture evaporation, but do not interfere oxygen and carbon dioxide
Transmission, do not influence crop blade face breathing, and with it is good biology and environmental safety, plant and environment will not be caused not
Good influence；
（2）The present invention utilizes ten several amino acid that Ammopiptanthus mongolicus body contains（Mainly dried meat acid）, drought resistings, the degeneration-resistant natural goods such as alkaloid
Matter is combined with drought resisting element, can keep and improve plant cell affinity and water holding capacity, can prevent cell dehydration so that is planted
Object cell has the drought-resistant ability of aobvious person, reduces plant moisture transpiration rate, reduces the unnecessary water consumption of plant, dramatically increases
Chlorophyll content improves photosynthesis, enhances plant enzyme system physiological activity, stimulates plant root growth.
