Abstract
The invention discloses a cold-resistant composition for tea trees, which is applied to a cold-resistant regulator suitable for each tea tree variety and reduces low-temperature freezing damage loss. According to the technical scheme, the composition is characterized by consisting of the following raw materials in parts by weight: 100 parts of 100-200mg/L ethylene, 100 parts of 100-200mg/L abscisic acid, 0.5 part of potassium nitrate, 0.3 part of magnesium sulfate, 0.5 part of urea, 0.5 part of sucrose and 0.5 part of potassium dihydrogen phosphate. Preferably, the concentration of ethylene is 200mg/L, and the concentration of abscisic acid is 100mg/L.
Description
Technical field
The invention belongs to the cold-resistant compositions field of tea tree, thereby especially a kind of cold-resistant regulator that is fit to each tea tree breed application reduces the cold-resistant compsn of tea tree of low temperature freezing-disaster loss.
Background technology
Low temperature freezing-disaster brings very big loss to tea tree, and the cold tolerance that strengthens tea tree is that people are making great efforts the problem that solves always.Though the appearance of cold-resistant compsn is also arranged, the problem that exists is that cold-resistant effect is undesirable.
Summary of the invention
Thereby the purpose of this invention is to provide the cold-resistant compsn of tea tree that a kind of cold-resistant regulator that is fit to each tea tree breed application reduces the low temperature freezing-disaster loss.
Technical scheme of the present invention is: the cold-resistant compsn of tea tree is characterized in that being made up of the raw material of following weight part: concentration 100-200mgL
-1100 parts of ethene, concentration 100-200mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Be preferably concentration 200mgL
-1Ethene, concentration 100mgL
-1Dormin.
Effect of the present invention is: the cold-resistant compsn of tea tree, form by the raw material of following weight part: concentration 100-200mgL
-1100 parts of ethene, concentration 100-200mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Test-results shows, in natural temperature-fall period, sprays the cold-resistant adjusting compsn of external source and can protect tea leaf to avoid freeze injury to a certain degree; Reduce the blade membrane permeability, alleviate the degraded of soluble proteins, increase the content of osmoregulation material such as soluble sugar, proline(Pro) and Put; Thereby improve the concentration of enchylema, strengthen the water-holding power of cell, reduce freezing point; Keep the stable of blade cell membrane structure, and then improve the cold tolerance of body, be beneficial to the tea tree safe overwintering.
Below in conjunction with not limiting embodiment the present invention is done further explanation.
Embodiment
Embodiment 1: the cold-resistant compsn of tea tree, form by the raw material of following weight part: concentration 200mgL
-1100 parts of ethene, concentration 200mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Weigh each raw material by component, plant is carried out foliage-spray.Simultaneously corresponding clear water being made in contrast handles.Spraying method be per seven days once, amount to three times, leave dual sides evenly sprays, degree is with solution spontaneous current degree of being down.Sampling:, whenever biweekly, amount to four times from spraying beginning for the first time.
Embodiment 2: the cold-resistant compsn of tea tree is characterized in that being made up of the raw material of following weight part: concentration 200mgL
-1100 parts of ethene, concentration 100mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Method of use is with embodiment 1.
Embodiment 3: the cold-resistant compsn of tea tree, form by the raw material of following weight part: concentration 100mgL
-1100 parts of ethene, concentration 200mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Method of use is with embodiment 1.
Embodiment 4: the cold-resistant compsn of tea tree, form by the raw material of following weight part: concentration 100mgL
-1100 parts of ethene, concentration 100mgL
-10.5 part of 100 parts of dormins, 0.5 part in saltpetre, 0.3 part in sal epsom, 0.5 part in urea, 0.5 part of sucrose and potassium primary phosphate.
Method of use is with embodiment 1.
Principle of work of the present invention is: dormin and ethene are growth regulatory substances important in the plant materials, and they play regulating effect at the different growth and development stages of plant, simultaneously also involved in plant coerce reaction, almost exist with the reaction of all plant adverse circumstances in.And elements such as C, N, K also play an important role in the process of plant-growth.
Test-results shows, in natural temperature-fall period, sprays the cold-resistant adjusting compsn of external source and can protect tea leaf to avoid freeze injury to a certain degree; Reduce the blade membrane permeability, alleviate the degraded of soluble proteins, increase the content of osmoregulation material such as soluble sugar, proline(Pro) and Put; Thereby improve the concentration of enchylema, strengthen the water-holding power of cell, reduce freezing point; Keep the stable of blade cell membrane structure, and then improve the cold tolerance of body, be beneficial to the tea tree safe overwintering.
Simultaneously, each handles tea tree cold tolerance enhanced action effect different, first and last, and ETH 100mgL
-1+ ABA200mgL
-1Treatment effect is best, explains that cold-resistant adjusting composition concentration plays a driving role within the specific limits, when some material concentration is too high, then can show certain restraining effect.
