Abstract
The invention discloses a pesticide and a method for controlling rate of fallen leaves of largeflower-like honeysuckle flower twig cutting seedling. The pesticide comprises the effective ingredients of 6-benayl aminopurine, sodium 2,4-dichlorphenoxyacetic acid and compound sodium nitrophenolate. The invention also provides a method for controlling the rate of the fallen leaves of the largeflower-like honeysuckle flower twig cutting seedling, comprising the steps of quickly dipping blades at the top of the twig cutting seedling into the pesticide and then raising seedling, wherein depth of the blades dipped into the pesticide is 4-7cm in quick dipping treatment, and quick dipping time is 10-30s. The pesticide can effectively solve the problem that leaves are fallen in a rooting process of the existing largeflower-like honeysuckle flower twig cutting seedling and can be applied to large-area largeflower-like honeysuckle flower cutting seedling raising, quantity of the fallen leaves is reduced by 50-70%, and survival rate reaches up to 80-90%; and the pesticide is practical and convenient and low in cost.
Description
Technical field
The invention belongs to plant biotechnology field, relate to a kind of medicament and method of controlling largeflower-like honeysuckle flower epicormic branch cutting defoliation yield.
Background technology
Largeflower-like honeysuckle flower is the main flow kind of southern area honeysuckle cultivation, has effect clearing heat and detoxicating, cool breeze heat radiation.Wide adaptability, strong stress resistance, cold-resistant, drought-enduring, barren-resistant, disease and insect resistance, requires not tight to soil.But in recent years, there is the problem that kind falls behind, seedling quality is degenerated in largeflower-like honeysuckle flower, although also there is the report of breeding of new variety, for example Wang Xiaoming is found florescence corolla indehiscent new varieties ' Jin Cuilei ', ' silver-colored emerald green flower bud ' and ' white clouds ' always in largeflower-like honeysuckle flower.Owing to adopting at present grafting methods breeding nursery stocks, reproduction coefficient is little more, and growing-seedling period is long, and infectivity germ, and deterioration of variety is fast.In order to accelerate the application of new varieties, do not stint and adopt tissue culture quick breeding nursery stock, but group training seedling production cost is too high, is difficult to large scale application in production.Set up cutting orchard take group training seedling as female parent, adopt cottage propagation nursery stock, can preserve the good genetic character of maternal plant, can significantly reduce production costs again.
No. 102405759A " a kind of cuttage seedling culturing method for branch culture of honeysuckle " patent of publication number CN, applicant's inventive features is that processing step is preparation training branch nutrient solution, preparation training branch base-material, cuts and pluck cutting, culture of rootage, seedbed arrangement, cuttage and seedling management etc.; No. 102640631A " cuttage and seedling culture method of a kind of honeysuckle " patent of publication number CN, applicant's inventive features is the cuttage selection in season, cuttings selection and processing etc.
The research of largeflower-like honeysuckle flower cuttage and seedling culture aspect is more, but be confined to the research of the aspect such as variation of nutrition content in general Technique on Cuttage Propagation, rooting mechanism and cottage propagation process, there is no the research of largeflower-like honeysuckle flower epicormic branch cutting control fallen leaves medicament.According to the study, largeflower-like honeysuckle flower is cultivated certain time limit, physiological age time bigger than normal, the rattan of germination and growth has hollow more, easily withered after cuttage, cuttings blade easily comes off, and defoliation yield, up to 80～90%, causes cuttings cuttage dead not as good as taking root afterwards, significantly reduce the survival rate of cuttage nursery stock, increase cuttage seeding production cost.Therefore, the medicament of research largeflower-like honeysuckle flower cuttage and seedling culture control fallen leaves is most important.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and a kind of medicament and method of controlling largeflower-like honeysuckle flower epicormic branch cutting defoliation yield is provided, and for largeflower-like honeysuckle flower epicormic branch cutting, improves cuttage root-taking rate and survival rate.
For achieving the above object, technical scheme provided by the invention is:
A medicament of controlling largeflower-like honeysuckle flower epicormic branch cutting defoliation yield, is characterized in that, described medicament comprises the raw material of following weight portion:
6-benzyl aminopurine 200～500
2,4-Dichlorophenoxyacetic acid sodium 50～100
Compound sodium nitrophenolate 3000～4000.
Preferably, described medicament comprises the raw material of following weight portion:
6-benzyl aminopurine 200～450
2,4-Dichlorophenoxyacetic acid sodium 50～95
Compound sodium nitrophenolate 3200～3800.
Preferably, described medicament comprises the raw material of following weight portion:
6-benzyl aminopurine 200
2,4-Dichlorophenoxyacetic acid sodium 50
Compound sodium nitrophenolate 3200.
Preferably, described medicament comprises the raw material of following weight portion:
6-benzyl aminopurine 350
2,4-Dichlorophenoxyacetic acid sodium 85
Compound sodium nitrophenolate 3800.
Preferably, described medicament comprises the raw material of following weight portion:
6-benzyl aminopurine 450
2,4-Dichlorophenoxyacetic acid sodium 95
Compound sodium nitrophenolate 3500.
The preparation method of above-mentioned medicament can adopt this area conventional means:
A) first use 95%(V/V) ethanol by 6-benzyl aminopurine hydrotropy, then 2,4-Dichlorophenoxyacetic acid sodium and compound sodium nitrophenolate water are dissolved; Wherein, cosolvent ethanol can substitute with certain density sodium hydroxide;
B) solution of above-mentioned alcohol hydrotropy and the aqueous solution two components are mixed, the constant volume that adds water, the stoste that stirs made adopts brown glass container, keeps in Dark Place for subsequent use under 5 ± 2 ℃ of temperature environments.
The present invention also provides a kind of method of controlling largeflower-like honeysuckle flower epicormic branch cutting defoliation yield, comprises the steps:, with above-mentioned medicament, shoot cutting tip of the spike blade is carried out to quickly dipped processing, then grows seedlings; The degree of depth that described quickly dipped processing Leaf is dipped into medicament is 4～7cm, and the quickly dipped time is 10～30s.
In largeflower-like honeysuckle flower cuttage process, owing to departing from parent, blade can not receive the supply of maternal nutriment again, and petiole base easily forms absciss layer, causes leaf abscission.6-benzyl aminopurine in medicament of the present invention can promote cell division and lateral bud to occur, and prevents agingly, also can promote the accumulation of biological substance in vivo simultaneously; Low concentration 2,4-Dichlorophenoxyacetic acid sodium can prevent leaf abscission effectively; Compound sodium nitrophenolate can accelerate cellular plasm and flow, and has removing toxic substances and more creates use, strengthens resistance.By 6-benzyl aminopurine, after 2,4-Dichlorophenoxyacetic acid sodium and compound sodium nitrophenolate wiring solution-forming, soak cuttings, can prevent cuttings leaf abscission, and blade do not come off and can protect resting bud, and the physiological activity of bud is conducive to the accumulation of nutriment.In addition, under the photosynthesis of blade, further stimulate and promote largeflower-like honeysuckle flower cuttage root-taking.
When the epicormic branch cutting that medicament of the present invention is applied to largeflower-like honeysuckle flower is put into practice, result shows, the middle defoliation yield of growing seedlings reduces by 50～70%, survival rate reaches 80～90%, when large-area applications, rooting percent and cuttage survival rate significantly improve, and average survival reaches 87%, improve on year-on-year basis 50%～70%.
