Description
Technical field
The invention discloses a kind of preparation methods of ornamental plant cryoprotective agent, belong to technical field of plant protection.
Background technology
Ornamental plant including woody and draft sight flower, sees leaf or fruit effect plant and suitable for gardens, greenery patches and wind
The securing plant and economic plants of scape Scenic Area.The ornamental plant of indoor flower also belongs to ornamental plant.Ornamental plant is divided into wood
Two major class of this ornamental plant and herbage landscape plants.
Within the period of garden plant growth, because of the climate reasons such as low temperature, cold spell in later spring, early late frost, often frost bitten, and
It can not restore, so as to cause the death of ornamental plant, undesirable economic impact and environment be caused to influence.
Therefore, the low-temperature protection of ornamental plant more acts on, and can avoid the loss of ornamental plant.How ornamental plant is improved
Resistance to frost, it is on the one hand related with the resistance to frost of ornamental plant in itself, be on the other hand exactly to take artificial means, protect garden
Woods plant avoids the infringement of low temperature as possible.
In manually protection field, for different plants, the method taken also is not quite similar, and for garden greenland, can adopt
Overlay film safeguard measure is taken, to there is the ornamental plant of economic value, greenhouse can be built or build straw shed temporarily, and some are woody
Plant or other ornamental plant for protecting place can not be provided, just opposite to its measure is simple.Especially xylophyta,
For a long time, all it is to coat one layer of protective coating in tree root and trunk lower part, the measure at other positions is relatively fewer, can only cope with
General microthermal climate, and when there is more severe microthermal climate, the effect of protection is limited.
CN 103719176A disclose the patent document of a kind of " a kind of plant-antifreezing liquid ", including following unit of weight
Component：2-5 parts of paraffin, 5-8 parts of vegetable oil, 4-8 parts of polybutene, 3-9 parts of potassium fulvate, 5-9 parts of benzoic acid, 2-6 parts of tea polyphenols,
2-5 parts of citric acid；Cassia twig, bush, ginger, radix ampelopsis 2-5 parts of cooking liquor.The technical solution is relatively simple, it is intended that is swashed by enzyme
Live plant cells reduce freezing point value, so as to reduce the erosion of low temperature.But in practice, effect is unsatisfactory, there is two aspects
Reason：First, the freezing point of anti-icing fluid in itself is higher, is influenced by low temperature, and plant can be damaged instead；Second, not
There is effective enzyme activition effect, intracellular freezing point value variation is not obvious, can change cell permeability instead, increase the shadow of low temperature
It rings, therefore, the program is unsatisfactory.
Invention content
It is insufficient in terms of low-temperature protection present invention aim to address ornamental plant, the defects of overcoming resistance to frost poor,
Provide a kind of preparation method of ornamental plant cryoprotective agent.
Technical solution：
A kind of preparation method of ornamental plant cryoprotective agent, includes the following steps：
The preparation of 1st step, modified poly ester polyalcohol：By weight, 20~35 parts of polyalcohol, 5~15 parts of adipic acid, nonyl are taken
0.5~1.5 part of 5~10 parts of diacid, 0.1~0.5 part of catalyst, 2~5 parts of ethyl alcohol, 3~5 parts of acrylate and vinyl acetate
It is put into reaction kettle to be reacted, 155 DEG C~185 DEG C of reaction temperature, after reaction, removed by evaporation moisture obtains modified poly ester
Polyalcohol；
The preparation of 2nd step, Nano filling：By weight, 1~2 part of oyster shell whiting, 0.5~1.5 part of medical stone powder, silicon are taken
Sour 0.5~2.0 part of aluminium powder is put into 1.5~3.5 parts of calcined kaolin in nano-level grinder, after grinding distribution 1h, adds in 95% second
Alcoholic solution, grinding 2h drying, obtains Nano filling；
3rd step, by weight, takes modified poly ester polyalcohol, Nano filling, 2~5 parts of sodium alginate, ethylene glycol 5~15
1~3 part of part, refined 1~2 part of peach gum powder, 2~3 parts of butyl polyacrylate and oleic acid glycol ester, are put into container, with stirring
Device stirs evenly, you can.
Preferably, in the 1st step, polyalcohol is ethylene glycol, propylene glycol, diglycol, trimethylolpropane,
Pentaerythrite and 1,4-butanediol it is one or more.
More preferably, in the 1st step, polyalcohol is ethylene glycol, trimethylolpropane, pentaerythrite and 1,4-butanediol
It is one or more.
Preferably, in the 1st step, catalyst is butyl titanate or tetraisopropyl titanate.
Preferably, in the 1st step, reaction temperature is 158 DEG C~175 DEG C, 2~3h of time.
Preferably, in the 2nd step, the average grain diameter of Nano filling is 50~200nm.
The preparation method of ornamental plant cryoprotective agent provided by the invention is a kind of the effective of raising plant resistance to frost
Method.By being modified to polyester polyol, the performance of polyester polyol is improved；On the one hand the preparation of Nano filling is stablized
Protectant performance, on the other hand also improves a large amount of mineral element；Utilize modified poly ester polyalcohol and Nano filling
Effect with reference to the selection of other compositions, is overlying on plant surface, there are three advantage performances for tool：First, coat the coating formed later
Itself has certain protective effect to plant, and protectant freezing point is relatively low, not-easy-to-freeze, this is first layer for ornamental plant
Protection；Secondly, protective agent part is penetrated into plant, will not increase the permeability of plant cell membrane, and can inhibit biomembrane
By the transformation of the opposite gel state of liquid crystal, the freezing point value of cell is reduced, effectively avoids intracellular ice；Third, protective agent easily drop
Solution, and the mineral matter element containing many plant productions, are quickly repaired conducive to ornamental plant, so as to be further reduced low temperature
Injury.
Therefore, the preparation method of ornamental plant cryoprotective agent provided by the invention, can significantly reduce plant cell ice
Point value reduces low temperature and is adversely affected caused by plant.
