Description
The present invention relates to a kind of double solvents, this double solvents can be used for regulating the process of growth of plant.Specifically provide a kind of cell membrane stability that improves the Chinese chestnut branch, make it not be subjected to or be subjected to less the cold resistant agent for Chinese chestnut growth of injury from low temperature.
Chinese chestnut also claims chestnut, is the very high deciduous tree of a kind of economic worth, and richness originates in warm area, China Liaoning.Its fruit is edible, and timber is solid, line is thin directly, structure is thick, durable, and for usefulness such as system floor, rudder for ship, vehicles, bark and timber can be carried tannin extract, and leaf can be raised tussah.It is not cold-resistant that but the main outstanding problem of developing this economic crops is a chestnut sapling.Be embodied in: its acrial part was dead because of freeze injury when the children who builds the garden field planting made Li Miao survive the winter every year, and next year is again with the following collar in face of land place germinating water sprout and form new plant.This phenomenon generally will repeat 3 years left and right sides time, then will repeat for five years than cold district, has seriously influenced planting of Chinese chestnut.How to improve the cold tolerance that the children makes chestnut, become these areas technical problem underlying anxious to be solved.
On the other hand for improving the cold resistance of plant, people have carried out a large amount of theoretical researches, for example, new Physiology and biochemistry theories such as free radical enzyme theory, ionic effect theory, plant low temperature injury mechanism, hormone regulation theory, and various practical winter protection technology have been proposed.But, do not see as yet so far can integrated use above-mentioned theory, adopts a kind of effectively, simply method is carried out the technology of coordinate plant growth.
The purpose of this invention is to provide a plant growth cold-resistance agent.Utilize this cold-resistance agent to be sprayed on the Chinese chestnut branches and leaves, can improve the chestnut sapling cold tolerance, make the chestnut sapling safe overwintering.
Integrated use of the present invention ionic effect theory, free radical and enzymology theory and hormone theory, promptly the utilization mainly be K
+, Na
+, Ca
+The stabilization that the plasma cell membrane is risen is as making the ionization of effective running of ionic pump under the adverse circumstance environment; For effectively removing crop is destroyed bigger various free radicals, utilize enzyme and non-enzyme such as superoxide dismutase (SOD), ethanol, benzoic acid, 3-sulfenyl propionic aldehyde, mannitol, glycerine, thiocarbamide, α-ketone group-4-methylmercapto butyric acids (KTBA) etc. and utilize water balance in the hormone regulation plant corpus prevent that the reduction of glutathione and phosphatide from causing resistance to strengthen, and then the anti-freezing property of raising plant, hormone with this effect has abscisic acid (ABA), 2,4-D (2,4 dichlorophenoxyacetic acid), NAA (naa) or CCC (chlorochline chloride) etc.For promoting above-mentioned three kinds of effects, in plant growing cold-resistance agent of the present invention, add derivant again, derivant can make ion, molecule enter effectively in the plant cell, can be used as the polyethylene glycol that has of derivant, dimethyl sulfoxide (DMSO) (DMSO) etc.By above-mentioned, of the present invention plant growing cold-resistance agent by containing K
+, Na
+Or Ca
+The mineral salt of ion are removed enzyme and non-enzyme, plant hormone and the derivant of harmful free radical and are formed, as the plant growing cold-resistance agent that is used for Chinese chestnut by CaCl
2, the mixed solvent formed of abscisic acid, mannitol, thiocarbamide, glycerine, dimethyl sulfoxide (DMSO) and water, each components contents is in per 1 liter cold-resistance agent: CaCl
2100～250mg; Polyvinyl pyrrolidone 400～500mg; Mannitol 1500～1800mg; Thiocarbamide 1300～1600mg; Glycerine 10～16ml; DMSO 10～16ml; All the other are deionized water.Can also add glucose and vitamin auxiliary elements such as (mainly being Vc) in Chinese chestnut plant growing cold-resistance agent of the present invention, its addition is 100～400mg/L glucose, 1～10mg/L vitamin.
The compound method of plant growing cold-resistance agent of the present invention is very simple, at first mineral salt is dissolved in the part water, again with each component mixing and stirring, adds to a certain amount ofly at last with deionized water, can be mixed with cold-resistance agent of the present invention.
The using method of cold-resistance agent of the present invention is also very easy, as long as with cold-resistance agent after cold-resistance agent or the rare system, in certain season, spray on the branches and leaves of chestnut sapling, soup will be entered the cell interior of tree body by plant endepidermis pore, by photosynthesis, thereby can realize improving the cold tolerance of children's order tree.In addition, cold-resistance agent of the present invention is to the person poultry harmless, environmentally safe, and cost is low, the efficiency height.When specifically spraying, require under regular hour and environment, to carry out.Should use in conjunction with the local climate condition, mainly be local variations in temperature, be preferably in for the first time frost and came preceding 15～20 days, or in the woods preceding 15～20 days spray usefulness of generally falling leaves, and when sunshine is sufficient, carry out.Because this moment, the trees physiological activity weakened, be about to enter dormancy.Cold-resistance agent enters behind the cell not can very fast metabolism, transfer.Accumulate in the branch cell with crack and cell, it is played a role.Spray cold-resistance agent about one week, leaf can come off by nature, and branch can enter dormancy as early as possible like this, thereby makes cold-resistance agent protect branch to survive the winter effectively.
Below by example technology of the present invention is given to illustrate further.
