Abstract
The invention belongs to the technical field of plant dormancy regulation control, and discloses a plant dormancy agent for prompting dormancy of trees by regulating before the trees are transplanted and a preparation method of the plant dormancy agent. The preparation method comprises the following steps of: dissolving 0.02-0.1g of calcium chloride into 100ml of water; dissolving 0.01-0.05g of oxaloacetic acid into 100ml of water; dissolving 0.1-0.5g of dimethyl amino succinyl amino acid into 100ml of water; dissolving 0.2-0.5g of choline chloride into 100ml of water; dissolving 0.005-0.03g of abscisic acid into 100ml of water, adding 5ml of polysorbate 20, and uniformly stirring; and mixing and shaking up the solutions, and enabling a volume to be 1000ml, so as to obtain the plant dormancy agent. The plant dormancy agent provided by the invention prompts lamina stomata to be closed by regulating the activity of key enzymes for physiological metabolism inside a plant body and changing the content of partial life regulation matter of the plant body, so that the transpiration rate of the water is reduced, and the metabolic rate of the water of the plant body is reduced.
Description
Technical field
The invention belongs to plant dormancy and regulate the control technology field, particularly a kind of trees regulate and control to promote plant dormancy agent of dormancy and preparation method thereof before transplanting.
Technical background
In landscape engineering, tree grafting growth is one of basis of afforestation, green barren hill engineering, and the tree grafting growth engineering is just carried out after the hard view is completed, and is subjected to the restriction of construction period, and tree grafting growth differs and establishes a capital in resting stage.But in the Annual growth cycle of trees, the survival rate of transplanting in resting stage is the highest, and vital movement animated period transplanting success is lower, and the landscape engineering project usually causes larger economic loss because transplanting big tree is dead.Large tree anniversary implantation technique is significant for Tree in Urban Garden Construction.
For improving the survival rate of transplanting, it is one of major measure in the tree grafting growth construction that tree crown is carried out strong the pruning.Though strong pruning of tree crown can make the transplanting survival rate of trees significantly improve, but to large tree behead, the method for the heavy pruning such as lopping rebuilding not only causes tree vigo(u)r weak, recover slow, being subject to damage by disease and insect infects, but also have a strong impact on landscape effect, transplant the ecological functions of trees, also need the long period just can be restored.Be in the trees before and after transplanting, due to the change in habitat, need to reduce the trees metaboilic level, reduce the consumption of nutrient and moisture, to adapt to new growing environment.It is one of key link of regulation and control trees physiological metabolism balance by the plant dormancy period regulation.For overcoming the above problems, in work progress, common method is that transplanting is carried out illumination and cooling processing now, and induced dormancy, the method only adapt to the part deciduous species, and cost is high.
The present invention carries out dormancy to trees and induces before tree grafting growth, reduce the physiological metabolism activity of trees, help trees to spend the unfavorable growth time, " do not know with tree " when accomplishing to transplant, overcome annual season limit and the technology barriers of transplanting of trees, improved the tree grafting growth survival rate.Cost is low, consumes less, and it is fast that trees recover, and the transplanting safety coefficient is high, easily forms landscape effect.
Summary of the invention
The present invention provides a kind of plant dormancy agent that improves the tree grafting growth survival rate in order to solve the problems of the technologies described above, and the trees before transplanting is carried out dormancy induce.
The present invention is by the following technical solutions:
The plant dormancy agent, the agent of every 1000ml plant dormancy is mainly made by the raw material of following content:
Calcium chloride (CaCl
2) 0.02-0.1g;
Oxaloacetic acid (OAA) 0.01-0.05g;
Dimethylamino amidosuccinic acid (B9): 0.1-0.5g;
Chlorination 2-chloro-N, N, N-trimethyl ethamine (CCC): 0.2-0.5g;
Abscisic acid (ABA): 0.005-0.03g;
Polysorbas20: 5ml;
Water: surplus;
Wherein, OAA chemistry oxosuccinic acid by name; B9 chemistry dimethylamino amidosuccinic acid by name; CCC chemistry chlorination 2-chloro-N by name, N, N-trimethyl ethamine; ABA is abscisic acid, chemistry 2-cis by name, and 4-is trans-5-(1-hydroxyl-4-oxo-2,6,6-trimethyl-2-cyclohexene-1-yl)-3-methyl-2,4-the eleventh of the twelve Earthly Branches dienoic acid; Polysorbas20 chemistry polyoxyethylene 20 sorbitan monolaurate by name.
The present invention also provides the preparation method of dormancy agent, and its preparation method comprises the following steps:
The first step weighs calcium chloride 0.02-0.1g, is dissolved in 100ml water, and is standby; Ca
2+With calmodulin (CaM) combination, form the second messenger, play the effect that information is transmitted, coordinate each several part metabolism in plant corpus;
Second step weighs oxaloacetic acid 0.01-0.05g, is dissolved in 100ml water, and is standby; Oxaloacetic acid is the substrate of citrate synthase, and citric acid is the negative effector of ATP-phosphofructokinase and pyruvate kinase, can effectively suppress the respiratory rate of plant.
The 3rd step weighed dimethylamino amidosuccinic acid 0.1-0.5g, was dissolved in 100ml water, and is standby; The dimethylamino amidosuccinic acid is the antigibberellin compound, suppresses plant corpus CA3 biosynthesis, reduces the content of trees body inner gibberellin, suppresses the cell division of apical meristem.
The 4th step weighed chlorination 2-chloro-N, N, and N-trimethyl ethamine 0.2-0.5g is dissolved in 100ml water, and is standby.Chlorination 2-chloro-N, N, N-trimethyl ethamine has antagonism to plant corpus GA3, can offset GA3 to the facilitation of vegetation growth of plant.
The 5th step weighed abscisic acid 0.005-0.03g, was dissolved in 100ml water, added the 5ml polysorbas20, stirred, and is standby; Abscisic acid suppresses the activity of protein synzyme in plant corpus, affect the synthetic of protein in plant corpus, changes the content of plant corpus part life Auto-regulator, closes Stoma of Leaves, reduction moisture transpiration speed; The transportation that reduces assimilation substance distributes, and plant corpus physiological metabolism speed is slowed down, the inducing plant physiological dormancy.
The 6th step, mentioned solution is mixed shaking up, be settled to 1000ml, can get the plant dormancy agent.
As preferably, described dormancy agent is applicable to woody plant.
As preferably, described woody plant is evergreen, Deciduous tree.
As preferably, dormancy agent 2 weeks before tree grafting growth are sprayed or input the tree body, spraying concentration is 0.1-0.5%, input concentration is 0.01-0.1%.
According to technical scheme of the present invention, the present invention has following beneficial effect: the activity of the key enzyme by the metabolism of regulating plant body physiological, change the content of plant corpus part life Auto-regulator, and impel Stoma of Leaves to close, reduce moisture transpiration speed, slow down plant corpus water metabolism speed; Impel plant respiration speed to weaken, delay Nutrition and Metabolism speed; Suppress the merismatic cell division of plant, plant corpus physiological metabolism speed is slowed down, induce to enter the plant physiology resting state, improve the survival rate of tree grafting growth.
