Description
[ technical field ] A method for producing a semiconductor device
The invention relates to an efficient defoliation method for evergreen magnolia, and belongs to the technical field of plant cultivation methods.
[ background of the invention ]
The Magnoliaceae plants are garden greening tree species with high ornamental value, are various, comprise fallen leaves to evergreen trees, shrubs to arbors, and are one of a few tree species which can be full of flowers and have fragrance to people. The magnoliaceae plants 16 belong to 240 species in total, 11 species and more than 100 species exist in China, are modern distribution centers and diversity preservation centers of the magnoliaceae plants, and are countries with the most abundant magnoliaceae plant resources. Although magnolia is widely applied to the field of landscaping at present, the widely used magnolia is limited to a small part of common species in magnolia, michelia and manglietia, which is not very suitable for the position in the garden plant community.
The middle and small-sized flowers and trees are the products with the largest market circulation of the current and future flowers and trees. Magnoliaceae plants are popular with people all the time, but are influenced by factors such as variety characteristics, cultivation technology and the like, the market share of the Magnoliaceae plants in China is extremely low, and domestic varieties are rarely circulated to foreign countries. In recent decades, domestic breeders breed a large number of new magnolia varieties with extremely high ornamental value and wide adaptability, and a large number of dwarf, flowerly and aromatic evergreen varieties are favored by foreign magnolia fans. At this time, the horticultural techniques and the distribution cost become major factors that restrict the application and popularization of new species of magnolia to foreign markets. In order to protect the development of the flower industry of China, some countries have strict inspection and quarantine requirements on imported seedlings. Compared with deciduous seedlings, evergreen seedlings are difficult to kill insects and bacteria, the transportation cost of the whole plant is extremely high, and the survival rate is lower if the seedlings are planted again after bare roots with leaves are transported.
[ summary of the invention ]
The invention aims to overcome the defects of the prior art and provide the efficient defoliation method for the evergreen magnolia plant, which can quickly promote the defoliation of leaves, improve the survival rate of transplantation and reduce the transportation cost. Is especially suitable for defoliation of medium and small size evergreen magnolia.
The purpose of the invention is realized by the following technical scheme:
an efficient defoliation method for evergreen magnolia is characterized by comprising the following steps:
(1) drought stress: watering the plant to be treated thoroughly, and then carrying out drought stress for 10-30d under natural conditions;
(2) preparing a medicament: diluting the Guoguang ethephon aqua with the effective component content of 40% by 100 times and adding 30mg/L abscisic acid according to the weight ratio of 1:1 equal volume mixing;
(3) and (3) induction implementation: in the afternoon without wind and with sufficient illumination, atomizing and spraying the medicament on the plants subjected to drought stress, ensuring that the front and back surfaces of all leaves are sprayed with the medicament, continuously treating for 2 times at intervals of 1d, wherein the treatment standard is that the liquid medicament on the leaves is in a water drop shape;
(4) and (4) post management: after the plant induction is implemented, the water at the root part is watered thoroughly in time to wait for the falling of the blade.
In the invention, after the plant induction is implemented and the root water is thoroughly poured, the leaves begin to fall off about 10 days, and the leaf-falling rate reaches more than 80 percent after the plant induction is implemented for 20 days.
The implementation treatment of the invention is carried out under natural conditions, no special production facilities and measures are needed, and the age of treated plants is required to be more than 3 years.
Preferably, for drought stress, the field planting seedlings are subjected to drought stress for 25-35 d, and the container seedlings are subjected to drought stress for 8-12 d. Drought stress may fluctuate depending on weather conditions, preferably until leaves begin to wilt slightly.
Preferably, the defoliation treatment time of the invention is 1-2 months, the treated leaves are ripe, and if the treatment is carried out in 8-11 months, tender leaves and tender branches are removed.
In the invention, when drought stress is carried out, a plastic film is built in the plant top of the field seedlings for rain shielding treatment.
The medicament used in the induction implementation of the invention is prepared at present, and the abscisic acid aqueous solution is photosensitive, belongs to a strong light decomposition compound and is suitable for preparation at present. When the abscisic acid solution is prepared, firstly, the abscisic acid is dissolved by 95 percent ethanol, and then purified water is added for constant volume. The specific operation is as follows: dissolving 30mg of abscisic acid powder into 95% ethanol for 3-5 times, adding abscisic acid powder after the solution is clear and transparent each time, adding purified water to 1000ml of constant volume after complete dissolution, and shaking up for later use.
Wherein, the induced implementation of the step (3) preferably selects windless and full-illumination weather, prevents the medicament from interfering the non-treatment object, the atomization spraying is the key for treatment, the medicament is required to be sprayed on the front surface and the back surface of the blade, the whole plant is uniformly sprayed, and a manual watering can or a sprayer can be used. The root water should be drenched in time after the induction of the medicament.
In the management after treatment, the invention requires that each watering is root irrigation watering, leaves cannot be wetted, the dilute release of the medicament is avoided, and the field seedlings are still subjected to rain shielding treatment after the root water is thoroughly irrigated.
Compared with the prior art, the invention has the following advantages:
the method has the advantages of simple and easy operation, low cost, convenient later management, convenient transportation, high survival rate after transplantation, quick restoration of landscape effect and the like, and can effectively relieve heavy manual operations such as manual leaf picking in Magnoliaceae.
By using the method, magnolia plants such as Guangdong michelia, Xiangxue michelia, Xianggu red michelia and Yushang michelia can germinate after being treated by tests for 28-32 days, the survival rate after being transplanted in other places reaches more than 95%, and the root system of the seedling is recovered quickly and vigorously in the later period.
The method is used for carrying out systematic regulation and control in the aspects of drought stress, medicament configuration, induction treatment, hormone type and concentration control and the like, researching the optimal method for efficiently removing leaves of medium and small size evergreen magnolia plants, and establishing a technical system so as to provide theoretical and technical support for development and utilization and further popularization and application of the magnolia plants. The evergreen magnolia plant after artificial defoliation can be transported with bare roots like the fallen magnolia, the branch bud is not damaged, the survival rate is high after the evergreen magnolia plant is planted again, the recovery is fast, and the problems of high circulation cost, difficult inspection and quarantine and the like can be effectively solved, so that the circulation of new species of the domestic evergreen magnolia in foreign markets is promoted.
