Description
Technical Field
The invention relates to a propagation method, in particular to a rapid propagation method for promoting female plants to bear fruits of North America ilex, and belongs to the technical field of plant cultivation.
Background
The Holly is perennial shrubs of Holly genus, the plants of Holly are female and male different plants, flowers are usually carried out in the middle ten days of 5 months, flowers are carried out at the beginning of 6 months, green fruits are grown in the middle ten days of 10 months, the fruits turn red, the leaves fall in the middle ten days of 12 months, the fruiting period is continued until 3 months in the next year, the fruiting period is long, and the Holly has strong resistance and adaptability, so that the Holly is a landscape plant such as gardens, families, offices and hotels, and is a main product of red fruits in the market of fresh cut flowers. However, the cultivation of the north american holly is long, and usually only needs five years to be marketed, and due to the characteristics of female and male different plants of the north american holly, a large number of female plants cannot be obtained in the cultivation process, and in addition, even the north american holly stock plant which only flowers and fruits for five years is cultivated, flowers and fruits only come into existence in the year after the current year of flowers and fruits come into existence, so that the cultivation of the north american holly is difficult, the cultivation of the north american holly is complicated, the growth speed is slow, the period is long, the plant is short, the result is difficult, and meanwhile, the plant is short, the plant is sold in a grading manner in a long-short size manner in the cut and sell process, and the north american potted landscape cannot be used in the potted flower sell, so that resources are wasted, the requirement of a high-end market cannot be met, the economy of flower farmers is seriously influenced, and popularization and application are greatly limited. Accordingly, there is a need for improvements in the art.
Disclosure of Invention
The invention aims to provide a propagation method for enabling each female plant to bear fruits and enabling the female plants of North America ilex to promote female plants to bear fruits with high plant height.
The invention is completed by the following technical scheme: the propagation method of female-promoting fruiting of the holly in North America is characterized by comprising the following steps of:
1) On each local pig iron winter green crop plant, 3-4 north american winter green female plants and one north american winter green male plant are grafted, and grown for 2-2.5 years to obtain a north american winter green finished plant with a plant height of 2.5-3 meters and a diameter of 8-12 cm;
2) Transplanting the finished plant in the step 1) into a flowerpot in a dormancy stage of 2-3 months, or turning red when the finished plant in the step 1) grows to the fruit color of 10 ten days above month, cutting fresh branches to supply the fresh cut flower market, and completing the propagation of female-promoting fruiting of the North American ilex.

12 Step 11), sprouting 26-32 days after sowing, transplanting the seedlings into red soil or yellow soil of a 100 multiplied by 10CM container when 4-5 leaves grow out, naturally growing for 4-6 months until the plant height is 30-40CM, then transplanting the seedlings into a field or greenhouse, and continuing to grow for 4-6 months until the plant diameter reaches 2-5CM and the plant height is 50-60CM to obtain the tie plants;
alternatively, 13) cutting branches with a length of 8-12cm from native naturally grown ilex pubescens, cutting in the following substrates: red soil and humus soil=1:1, growing for 4-6 months until the plant height is 30-40cm, transplanting into a field or greenhouse, and continuing to grow for 4-6 months until the plant diameter reaches 2-5cm and the plant height is 50-60cm, so as to obtain the tie plants.
The grafting of the step 1) is completed on the grafting plants of the subway winter green grown in the field, and a proper amount of water is poured once every week after grafting; after crops grow to bud, applying a water-soluble compound fertilizer according to the amount of 5 kg/mu once every 45 days, and growing for 22-24 months to obtain a finished product plant of North America ilex with the plant height of 2.5-3 m and the diameter of 8-12 cm;
or, the grafting of the step 1) is finished on local pig iron winter green grafting plants grown in a greenhouse, and after grafting, a proper amount of water is poured every week; after crops grow to bud, applying water-soluble compound fertilizer according to the amount of 5 kg/mu every 45 days, controlling the temperature in the greenhouse to be 25-30 ℃, keeping the natural illumination and natural ventilation of the greenhouse, and obtaining the finished product plant of North America holly with the plant height of 2.5-3 m and the diameter of 8-12cm after the crops grow for 20-22 months.
And in the growth process of the step 2), water and fertilizer management is carried out conventionally.
The insect control management of the steps 1) and 2): when eggs appear, spraying the corresponding insecticide once, and then spraying the corresponding insecticide once a month for 3-4 times in total to prevent insect pests.
And (2) disease prevention management of the steps 1) and 2): when diseases appear, spraying the corresponding disease-resistant agent once, and then spraying the corresponding disease-resistant agent once per month for 2-3 times to prevent diseases.
The subway ilex latifolia is a subtropical evergreen shrub or arbor in the family ilex, the height of the subway ilex latifolia can reach 20 meters, the breast diameter of the subway ilex latifolia reaches 1 meter, the subway ilex latifolia is straight, female and male heterogenic plants are straight, warm and moist climates are favored, the seedlings of the iron ilex latifolia are ordered, the germination rate is high, and the seedlings can safely overwinter in one year.
The invention has the following advantages and effects: by adopting the technical scheme, particularly, the north american holly is grafted on the subway holly, and the hermaphrodite is realized in a mode that 3-4 branches of female plants of the north american holly are grafted on the subway holly and one branch of male plants of the north american holly are grafted at the same time, so that finished plants of the north american holly with the plant height of 2.5-3 meters and the diameter of 8-12cm can be obtained in 2 years after grafting, if the cultivation time of the plants is added for 3 years, the cultivation time is greatly shortened, the annual flowering and fruiting can be kept, the plants can be used as cut flowers and branches to be marketed, the requirements of fresh cut flowers are met, the plants can be transplanted into flowerpots to be used as high, large and American potted plants to be marketed, the landscape effects such as gardens, families, offices and hotels are increased, the requirements of high-end users are met, the income of flower farmers is greatly increased, the problems of great difficulty in breeding, slow growth, long period, short and low fruiting in the north american holly are fundamentally solved, and the wide application of the plants in the prior art is facilitated.
