technical field

The present invention relates to the cultivation method of plant, more specifically, the present invention relates to the cultivation method of peony.

Background technique

Peony, scientific name Paeoniasuffruticosa Andr, belongs to Paeoniaceae (Paeoniaceae) Paeonia (Paeonia) plant, originates in China, has a history of more than 1600 years in my country. Hanzhong is the first place in China to artificially cultivate peony. Its flowers and leaves are very similar to peony, so peony was also called wood peony in ancient times.

Peony is known as the "king of flowers" and "the flower of wealth" for its extraordinary characteristics such as beautiful body, huge flowers, beautiful colors, and rich colors. It is also a symbol of beauty, happiness, auspiciousness, and wealth. Loved by people of all nationalities and overseas. The ornamental parts of peonies are mainly flowers, which are famous for their elegance and magnificence. Peonies can be planted in special gardens in parks and scenic spots; in classical gardens and residential courtyards, planted on flower beds; in gardens and green spaces, they can be planted naturally in isolation, clusters or in patches. It is also suitable for arranging flower borders, flower beds or flower belts, or potted plants, and is very flexible in application. The root bark can be used as medicine, and the petals can be used to make wine. It can be said that each organ of peony has important economic value.

Generally speaking, horticultural plants originating from temperate regions generally flower in spring, undergo flower bud differentiation in summer and autumn, fall leaves in late autumn, and go dormant in winter during their annual growth and development cycle. In the case of no dormancy or early release of dormancy, the second growth and second flowering in the same year is a phenomenon of phenological recurrence. Some peony varieties have the recurring phenological period under certain conditions in a year, that is, after the flower bud differentiation of peony is completed or partially completed (entering the stage of pistil and stamen petalization) in the current year, under suitable internal and external conditions, no After the dormancy process in winter, it germinates, grows, buds and blooms in the autumn of that year. We abbreviate this peony variety that is easy to germinate and grow in autumn as "Qiu Fa Peony" (Wang Lianying, 1998).

Autumn peony varieties are a special kind among many peony varieties. They can grow and bloom for the second time in autumn under suitable natural conditions, and they can bloom for the second time in the open field in autumn after simple artificial induction. It satisfies people's desire to appreciate peonies in two seasons, and the cost of secondary flowering cultivation is low, has broad development prospects, and lays a solid foundation for the industrial production of peonies for National Day.

As mentioned above, the natural flowering period of peonies is relatively short, and it is difficult to meet the needs of various festival flowers. For example, if the flowering period is not controlled, there will be no blooming peonies in the market during the National Day. Through timely defoliation, coupled with appropriate hormone treatment, some varieties can achieve flowering around the National Day.

The inventors found that selection has a shallow dormancy property. For special species with low demand for low temperature, manual defoliation at the right time, combined with appropriate hormone concentration treatment, can make the peony achieve the purpose of flowering on National Day.

detailed description

As mentioned above, the present invention provides a method for promoting the cultivation of potted peonies for National Day flowering, that is, a method for promoting flowering of potted peonies to be used for National Day flowering.

In the first aspect of the present invention, there is provided a cultivation method for promoting flowering of potted peony on National Day, said method comprising the following steps: 1) selecting a plant of a species of peony with autumn hair; 2) carrying out defoliation treatment on said plant; 3 ) smearing the buds of the defoliation-treated plants with autumn hairin, wherein the autumn hairin contains 600mg/L to 900mg/L gibberellins;

4) Upper basin.

Generally speaking, peonies originate from horticultural plants in temperate regions. During their annual growth and development cycle, they usually bloom in summer, undergo flower bud differentiation in autumn, shed leaves in late autumn, and dormant in winter. Under certain conditions, some peony varieties can also In the case of no dormancy or early release of dormancy, the secondary growth and secondary flowering in the same year are a kind of phenological recurrence phenomenon. The mixed buds of peonies with medium recurrence phenomenon complete or partially complete the flower bud differentiation in the current year (ie After entering the pistil petalization period), under suitable internal and external conditions, without going through the dormancy process in winter, it will germinate, grow, bud and bloom in the autumn of that year. We abbreviate this peony variety with the tendency or phenomenon of sprouting growth in autumn as "Qiufa Peony" (Wang Lianying, 1998).

The specific peony varieties of the present invention are not particularly limited, as long as they are autumn peony. But in some preferred embodiments, the qiufa peony variety is 'paeoniasuffruticosa 'cangzhihong' or 'watermelon pulp' (paeoniasuffruticosa 'xiguarang').

The present invention has no special limitation on the plant age of the autumn peony, but it is preferably a 4 to 5-year-old prime-age plant. If the plant age is too young, the branches will not have enough nutrition and it will be difficult to form flowers; if the plant age is too large, it will be difficult for the plants to get water and it will be difficult to form flowers.

In some embodiments, it is further preferred that each plant has 6 to 8 main branches; if there are too many main branches, it is not easy to manage potted plants and compete for nutrients, thereby affecting the quality of flowers; if there are too few main branches, it will affect the potted peony The overall beauty.

In addition, in some preferred embodiments, each plant preferably has at least 6 to 10 full terminal buds. If there are too many terminal buds, the nutrients will be dispersed, which will affect the quality of the flowers; if there are too few terminal buds, the fewer flowers will affect the overall appearance.

In order to make the peonies of autumn hair bloom again in the same year, in general, especially for potted peonies, it is necessary to manually break the dormancy of the mixed buds. Defoliation treatment is considered as a means to break the dormancy of peonies of autumn hair. In order to break dormancy, you can defoliate single branch, half plant or whole plant of Qiufa peony. However, in the method of the present invention, it is preferred to use full defoliation.

The method of defoliation is not particularly limited in the present invention, for example, physical defoliation (defoliation without the aid of chemical reagents) or chemical defoliation (such as defoliation using ethylene or abscisic acid or other defoliants) can be used. In the method of the present invention, physical defoliation is preferably used. In some embodiments, manual physical defoliation is preferred.

The present invention does not have strict requirements on the artificial defoliation time, generally 40-50 days before the National Day, defoliation prevents a large amount of ABA in autumn leaves from being transported to mixed buds, and keeps the ABA content in buds at a low level, thereby Promoted the germination of mixed buds. From the germination of the mixed buds to the flowering, it can be divided into 9 stages: the early stage of leaf removal, the germination stage, the bud display stage, the bud jumping stage, the small wind bell stage, the floating stage, the round bud stage, the initial flowering stage, and the full flowering stage. 45 days, the defoliation time may vary according to the variety and the nutritional status of the plant.

In the present invention, the sprouts are smeared with Qiufasu. In the present invention, the term "autumn" refers to a substance that can promote autumn germination of peonies for secondary flowering. In some embodiments of the present invention, the qiufalin is a solution containing gibberellin at a specified concentration, preferably an aqueous solution. Gibberellin is a widely existing class of plant hormones, and its chemical structure belongs to diterpenoid acids, derived from a tetracyclic skeleton. It is generally believed that it can stimulate the growth of leaves and buds, but different plant species or different varieties of plants of the same family have very different responses to gibberellin, and have significantly different concentration tolerances. At present, more than one gibberellins are known. In the present invention, the gibberellin preferably used is GA ₃ . The concentration of gibberellin is preferably 600mg/L to 900mg/L, such as 600mg/L, 650mg/L, 700mg/L, 750mg/L, 800mg/L, 850mg/L or 900mg/L. If the concentration of gibberellin is too high, it will stimulate the leaves to develop prematurely, resulting in the phenomenon of "leaves eating flowers", that is, more leaves and less flowers; if the concentration of gibberellin is too small, it will be difficult to achieve the desired effect.

In some embodiments of the present invention, it is preferred that the autumn hairin further comprises auxin and zeatin. During the experiment, the inventor unexpectedly found that adding auxin and zeatin to qiufasu can achieve significantly better results, while adding either zeatin or zeatin alone has basically no effect. In some embodiments, the weight percentage of gibberellin, auxin and zeatin is preferably 8:1:1.

Among the autumn hairins of the present invention, gibberellins such as GA ₃ are often used as growth regulators for agricultural plants. The physiological role of GA ₃ is to promote and break dormancy, and its main role in production is to promote vegetative growth and break dormancy. The growth-promoting effect of auxin is mainly to promote cell growth, especially cell elongation, and the combined use of zeatin and auxin helps to promote germination. In some preferred embodiments, 10 microliters of Tween reagent (Beijing Chemical Reagent Company) was added to every 10 ml of Qiufasu. When smearing, for example, you can use a brush with a soft tip to dip a small amount of autumn hair essence. It is advisable to dip the amount each time without liquid hanging drops, and apply it to the full terminal bud or first bud. To avoid nutrient competition, it is preferable to wipe off the rest of the mixed buds.

The present invention has no special limitation on the number and frequency of application. However, preferably, the smearing process smears the sprout once every 3 days, and smears continuously for 3 times. In addition, the present inventors unexpectedly found in the experiment that the qiufasu can achieve better effect by adopting the method of gradually increasing the concentration for smearing. For example, the smearing process smears the sprouts once every 3 days, and smears continuously for 3 times, wherein the gibberellin concentrations in the qiufalin in the 3 smearing treatments are respectively 800mg/L, 1200mg/L, and 1600mg/L. . In addition, in some preferred embodiments, the terminal buds are smeared, and all other buds that germinate on the plant and the tillering buds at the base of the plant are wiped off at the same time.

In order to make the peony of autumn hair bloom twice in a year, it is preferable to use the method of bringing soil lumps when potting. In order to make the autumn peony bloom during the National Day, the potting time is preferably carried out when the buds are in the round bud stage to the transparent color stage. For the determination of the round bud stage to the transparent color stage, please refer to "Chinese Peony and Paeoniae "(Li Jiajue, 1999). The relevant content of this document is hereby incorporated into this text. Among them, the characteristics of the round bud stage are as follows: the flower bud is full and full, and spreads and moves to the lower part of the flower bud; the transparent stage: the sepals are split, the outer petals are exposed, the sepals are moved to the middle and lower part of the flower bud, and the flower bud becomes soft.

In addition, in some embodiments, it is preferable to water once permeable after potting.

In the present invention, when potting with soil, it is further preferred to minimize the damage to the roots. For example, raise seedlings with a large soil lump, and then perform root pruning to remove obvious rotten and diseased roots. The length of the root left when potting can be 35-40cm, such as 35cm, 36cm, 37cm, 38cm, 39cm or 40cm. If the root system is kept too long, it will be difficult to pot and affect potting management; if the root system is kept too short, After being potted, it is difficult to absorb water and cannot supply enough nutrients to the branches, which affects flower formation. When raising seedlings, it is best to ensure that the core soil is left, so that the nutrients needed for peony flowering can be supplied in time, which is beneficial to the later growth of its roots.

The present invention has no special limitation on the used flowerpots, for example, a flowerpot with an appropriate height and diameter can be selected according to the height and diameter of the root cap and the height and diameter of the aboveground part. In general, flowerpots with a height of 40cm to 50cm (such as 40cm, 45cm or 50cm) and a diameter of 30cm to 60cm (such as 30cm, 40cm, 50cm or 60cm) can be used, if the flowerpot size (height and/or or diameter) is too small, it may not be possible to bury the underground part of the peony plant in the cultivation medium, or affect the further growth and development of the root; if the size is too large, it may be out of harmony with the proportion of the whole peony plant and lose the appearance.

The matrix used in the upper basin of the present invention is not particularly limited, for example, a mixed matrix comprising peat and perlite can be used.

After potting, the potted peonies can be managed by conventional cultivation methods.

In some other preferred embodiments, after the defoliation treatment and before the smear treatment, the defoliated plants are subjected to water control treatment for 10 to 15 days, for example, 10 days, 12 days, 14 days Day or 15 days of water control treatment. The so-called water control means not supplementing water through artificial means and avoiding the supplement of natural precipitation for plants.

In some preferred embodiments, after the water control treatment is completed and before being placed in the pot, the potted peonies are also watered thoroughly. In some other preferred embodiments, it is preferred to pour water once every two weeks during this period of time, and it is further preferred to keep the relative air humidity of the environment at 70%-80%, such as 75%, at the same time.

In some embodiments, it is preferable to carry out slow seedling treatment after potting. For example, place the potted plants in a cool place for 3-5 days, and at the same time, the day and night temperature is preferably not higher than 15°C. If the day and night temperature is too high, it is easy to cause the leaves to grow too fast, compete for the nutrients of the flower buds and affect the flower formation.

In some preferred embodiments, during the seedling slowing process, the relative humidity of the environment is maintained at 80%-90%, such as 80%, 82%, 84%, 86%, 88% or 90%. If the relative humidity is too low in the process of slowing down seedlings, it is easy to cause the plants to wilt, which is not conducive to the development of flower buds and thus affects flower formation.

In some preferred embodiments of the present invention, in order to further improve the commerciality of the potted peonies, after the seedling slowing treatment, the potted peonies are also subjected to seedling hardening treatment. There is no special restriction on the hardening of seedlings, for example, the hardening of seedlings can be carried out for 3 to 5 days. By adopting the method of the invention to cultivate the autumn peony, the potted peony can be opened during the National Day after the seedling hardening is finished.

Hereinafter, examples will be used to illustrate specific embodiments of the present invention, but these examples should not be construed as limiting the present invention to these examples.

Example

Examples 1 to 15

The experimental site is the Peony Resource Garden of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5-year-old autumn peony cultivar 'Cangzhihong' (paeoniasuffruticosa 'cangzhihong') with 8-10 vigorous branches were selected for defoliation of the whole plant. After defoliation, control water for 10 days, then wipe off the side buds, only keep a bud (generally the top bud or the first bud) closest to the top, and each embodiment adopts 10 plants. On August 25th, the retained buds were subjected to the first Qiufasu (the active reagents GA ₃ , auxin and zeatin included in it were all analytically pure, purchased from Beijing Chemical Reagent Company, and the concentrations were as shown in Table 1) Smudge treatment.

After the peony buds enter the translucent period, the seedlings should be raised at 16-17 o'clock in the afternoon (after the sun has weakened) to prevent the water from evaporating too quickly. Take protective soil when raising seedlings to reduce damage to the root system. After the seedlings are raised, the root system is trimmed to remove diseased and rotten roots, and the root length is about 38 cm. Plant the pruned plants in a flower pot with a height of 45 cm and a diameter of 36 cm. Fill the matrix (peat: perlite = 2:1 (volume ratio)) and water it immediately. Put the plants in a shady place and spray water three times a day in the morning, noon, and afternoon to keep the relative humidity of the environment at 70% to 80%. During flowering.

Table 1. The parameter values and the measured parameters of the 'Zangzhihong' variety for the National Day promotion cultivation treatment

It can be seen from the results in Table 1 that when only GA ₃ is included in the composition of Qiufasu, the flowering effect is better when the concentration of GA ₃ is 800mg/L; when zeatin is added to GA ₃ , the effect is different from that only containing GA3 Few, when zeatin and auxin (IAA) are used together, it can significantly promote flower formation. When the autumn hair contains GA ₃ , IAA and zeatin and the ratio of the three is close to 8:1:1, it can achieve a good effect of promoting cultivation.

Example 16

The experimental site is the Peony Resource Garden of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5-year-old autumn peony cultivar 'Cangzhihong' (paeoniasuffruticosa 'cangzhihong') with 8-10 vigorous branches were selected for defoliation of the whole plant. After defoliation, control the water for 10 days, then wipe off the side buds, and only keep the bud closest to the top (usually the top bud or the first bud). On August 25th, the retained buds were tested for the first time for autumn hair (the active reagents GA ₃ , auxin and zeatin contained in it were all analytically pure, purchased from Beijing Chemical Reagent Company, GA ₃ , auxin and corn The weight ratio of auxin and zeatin is 8:1:1, the same below), and the concentration of qiufalin (that is, the sum of the concentrations of GA ₃ , auxin and zeatin) used for the first application is 1000 mg/L. Thereafter, two smears were carried out successively every 3 days, that is, the second smear and the third smear, and the concentrations of the autumn fat used in the second smear and the third smear were 1500 mg/L and 2000 mg/L respectively.

After the peony buds enter the translucent period, the seedlings should be raised at 16-17 o'clock in the afternoon (after the sun has weakened) to prevent the water from evaporating too quickly. Take protective soil when raising seedlings to reduce damage to the root system. After the seedlings are raised, the root system is trimmed to remove diseased and rotten roots, and the root length is about 38 cm. Plant the pruned plants in a flower pot with a height of 45 cm and a diameter of 36 cm. Fill the matrix (peat: perlite = 2:1 (volume ratio)) and water it immediately. Put the plants in a shady place and spray water three times a day in the morning, noon and afternoon to keep the relative humidity of the environment at 70% to 80%. During flowering.

Examples 17 to 23

Cultivation was performed in the same manner as in Example 16 except for the contents listed in Table 2.

Table 2 The parameters used and measured parameters in the experiment of promoting national day flowering with the variety 'Zangzhihong'

As can be seen from the results in Table 1 and Table 2, the present invention can break the dormancy of the buds of the peony in autumn and make it germinate by defoliation treatment, but it cannot impel all the mixed buds to flower. For Qiufa peony, the defoliation treatment combined with the gradually increasing concentration of Qiufasu smear treatment makes Qiufa peony have significant effects in breaking dormancy, increasing flowering rate and shortening the growth period.

Examples 24 to 31

Except the content listed in table 3 and adopting ' watermelon flesh ' kind to replace ' Zangzhihong' kind, carry out according to the mode identical with embodiment 16.

Table 3 The parameters used and the measured parameters in the test of the 'Watermelon Flesh' variety to promote the cultivation of National Day flowering

Examples 32 to 38

Except for the contents shown in Table 4, it was carried out in the same manner as in Example 16.

Table 4 The parameter values and the measured parameters of the national day promoting cultivation treatment with the 'Zangzhihong' variety

The measurement methods of each index in the above tables are as follows:

Germination rate (%) = number of germinated buds / number of artificially treated buds × 100%

Flowering rate (%) = number of flowers / number of artificially treated buds × 100%

Abortion rate (%) = number of abortions / number of artificially treated buds × 100%

Plant flowering rate (%) = number of flowering plants / number of treated plants × 100%

Growth period (d) = days from treatment to full flowering

Full flowering period (d) = number of days for flowers to reach maximum diameter and remain open

As can be seen from the results in Table 4, the pots with "heart-protecting soil" and retaining 35-40cm root length of the present invention have a significant effect on promoting peony germination and flower formation. When the root length is kept above 45cm, better flower formation and germination rate can be guaranteed, but the increase of root length increases the difficulty of operation. For example, the need for larger flower pots may cause the proportion of plants and flower pots to be uncoordinated. Affect the appearance. Therefore, from the operational point of view, it is more appropriate to use a root length of 35-40 cm.
