Description

Seedling culture domestication method for dormant plants

Technical Field

The invention relates to a plant seedling raising method, in particular to a seedling raising domestication method of dormant plants.

Background

A dormant plant, which refers to a plant that is in a dormant state at a certain period of time during a growing period; dormancy refers to the phenomenon in which a plant body or organ grows at a certain stage of development and metabolism is temporarily halted. The dormancy is performed in winter in various types, while the plants in temperate regions are dormant in winter, most of perennial plants are dormant in winter, for example, deciduous trees (such as rosaceous plants as apple trees, peach trees, pear trees, cherry trees, apricot trees and the like, or succulent plants such as cactus, stonecrop and the like, or flowers such as China rose, pomegranate, peony and the like) are dormant basically; plants in high-temperature and arid areas in summer are dormant in summer, such as crocus sativus, narcissus, thunberg fritillary bulb, kochia scoparia and cyclamen. The dormancy form has various forms, and the first-year and second-year plants mostly use seeds as dormancy organs; perennial deciduous trees overwinter with dormant buds; perennial herbaceous plants which grow for two years or more spend a bad environment in the form of roots, stalks, bulbs, tuberous roots, tubers.

Dormancy is the period of time that must be spent in the growth cycle of dormant plants, and if these plants are not dormant or are not dormant for an adequate period of time, they will grow poorly or not flower and bear fruit in the next year. For example, winter wheat, winter dormancy of wheat seedlings is the growth characteristic of winter wheat, winter wheat seedlings after winter dormancy are quickly tillered in spring, and if winter wheat seedlings do not sleep in winter and grow under the condition of proper temperature all the time, the winter wheat seedlings are probably not tillered. For some perennial plants, the plants need to be dormant for several times to bear fruits, such as peach trees, leaves can only grow but not blossom and bear fruits in the first year and the second year after planting, and the plants can blossom and bear fruits every year after dormancy for the third time; these are all determined by the growth habit of the plant itself, namely the popular 'four-apricot and three-peach-plum five-year' theory.

However, for dormant plants, there is a minimum time limit for dormancy; this is the same as the minimum time for sleep assurance in humans, which remain asleep for six to seven hours per day. Taking a peach tree as an example, after the planted peach tree is subjected to low-temperature cold weather, the peach tree blooms in about March in spring, the peach in Wujune is ripe, and the blooming and fruiting only need about 4 months; leaves are fallen after the stimulation of frost and low temperature, and the fallen leaves mean dormancy, but the rest 8 months are not the dormancy period of the peach trees; the peach trees can only spend several months in the form of dormancy, but the peach trees do not sleep, the temperature, the sunlight, the frost and the dew and the like do not meet the requirement of dormancy, or the temperature, the sunlight and the like do not meet the requirement of resuscitation. If the peach trees after fruiting are stimulated to sleep in frost, low temperature, low light and the like in advance to enter and stay dormant, the most basic dormancy time of the peach trees is guaranteed, and then the peach trees are revived, then in 12 months of a year, are the peach trees not harvested for several more than one cropping?

If the peach trees are covered by the greenhouse to be heated and enough sunlight is given after the peach trees reach the lowest time period of dormancy under the natural condition in the local winter, the peach trees can be revived in advance, but the peach trees can only be harvested in advance and can not be harvested for a plurality of times a year. If the peach trees are carried into a cold storage and are dormant by low-temperature stimulation, the peach trees are transferred into a greenhouse for resuscitation after reaching the minimum time period of dormancy, a plurality of crops can be harvested, but the method has the following problems: the cold storage can only provide low-temperature stimulation, but cannot provide other conditions such as frost, illumination and the like, the dormancy belongs to forced dormancy, is not dormancy under natural conditions, and whether the peach tree can be successfully dormant, revived, bloomed and fruited or not is difficult to regulate and control; moreover, for plants, the roots of the plants are damaged after the plants are removed from the soil, and the plants are recovered after entering new soil again for a certain period of time no matter how careful the plants are; when the plants are moved out, the root systems of the plants wrap moist soil, the fertilizer cannot be applied during long-distance transportation, and the growth of the plants is limited to a certain extent; even if the plants are cultured in flowerpots, the plants grow into mature plants from seedlings and need to be subjected to pot changing, and the plants also need to adapt to the time during the pot changing process.

The applicant of the present invention has reported that two inventions, CN105191696A (seedling container and mobile seedling method using seedling container) and CN105746230A (seedling container and mobile seedling method), do not need to change the cultivation container during the whole process of crop growth, and the crops can move integrally with the original pot, thereby solving the problem that the change of cultivation container causes the crops to catch up, and avoiding the problem that the root injury and seedling delay affect the crop growth. In northern areas such as inner Mongolia and northeast China, the frosty period in one year is longer, taking the union of Silibinoguo as an example, only 3 months in 12 months in one year are frostless periods, and the rest 9 months are frosty periods; if plants needing winter dormancy can be moved to the cold northern areas to spend winter dormancy stimulation under natural conditions on the premise of not destroying the growth conditions of original soil, and then moved back to the local area for cultivation after dormancy is completed, harvesting more than one crop in one year can also be realized.

In the technical scheme, in the step (2), before the plant is sent to the northern outdoor area with frost period, the plant can be pruned conventionally according to the conventional operation in the field, so that the transportation convenience is improved.

In the technical scheme, in the step (2) and the step (3), the temperature of the northern outdoor with frost period is 0-5 ℃, and preferably about 2 ℃; most dormant plants sleep at a temperature ranging from 10 degrees to-40 degrees, and the outdoor temperature can meet the requirement of plant dormancy.

In the above technical scheme, in the step (2) and the step (3), the dormancy period required by the plant is preferably 200 hours, for example, most northern fruit trees such as apple trees, peach trees, pear trees, apricot trees, plum trees and the like are controlled to be about 200 hours. The dormancy stage adopts a low-temperature degradation dormancy method, and most fruit trees can be dormant in a low-temperature environment of 0-5 ℃.

In the above technical solution, in the step (2), the indoor domestication specifically means: artificially regulating and controlling light intensity, light cycle, temperature difference, moisture and fertilizer required by the plant in spring, summer and autumn indoors according to the plant growth characteristic of the plant per se, wherein the growth and development time, growth and development conditions and daily care of the plant in each season are operated according to the conventional technology in the field; the plant is domesticated indoors in spring, autumn and three seasons, and nutrition is accumulated.

In the above technical solution, in the step (3), the circulating production specifically means: artificially regulating and controlling light intensity, light cycle, temperature difference, moisture and fertilizer required by the plant in spring, summer and autumn indoors according to the plant growth characteristic of the plant per se, wherein the growth and development time, growth and development conditions and daily care of the plant in each season are operated according to the conventional technology in the field; the plant undergoes growth and development in spring, season and autumn indoors, the plant germinates in spring and blooms with ornamental value, the plant bears fruits in summer and has luxuriant branches and leaves to accumulate nutrition, the fruit is mature in autumn, the plant for harvesting the fruit is placed outdoors in frost, and the cycle production is repeated.

In the above technical solution, in step (3), the permanent planting specifically means: after the plants are domesticated in a dormant manner in winter, the plants are cultivated indoors according to a conventional method according to the plant growth characteristics of the plants, and then are planted in outdoor soil in spring, summer or autumn.

According to the method, the domestication seedling raising method of the hibernating plants can be analogized.

The technical scheme of the invention has the advantages that:

(1) the method can shorten the time for the plants to bloom and bear fruits without influencing the growth and development of the plants: under natural conditions, the third year of peach planting, the fourth year of plum planting and the fifth year of apricot planting can bear fruit; taking apple trees as an example, generally, the apple trees are dormant in winter after growing and developing in the first year (about 4 months), continue dormant in winter after accumulating nutrition in the second year (about 4 months), and bloom in the third year for four and five months from the beginning of planting or grafting; the actual time for the apple trees to hibernate in winter is not 8 months but is guaranteed to be about 200 hours. By adopting the method, the apple trees needing dormancy are dormant for 200 hours under outdoor natural conditions and then transferred to the indoor environment, the apple trees are cultured for about 4 months according to the growth and development conditions of spring, summer and autumn required by the growth characteristics of the apple trees, and then the apple trees are moved to the outdoor dormancy … …; therefore, the apple trees can complete the whole process of 2-3 times of growth and development within 1 year, the apple trees do not need 3 years to blossom and bear fruits, and only 1 year, half or 1 year is needed to blossom and bear fruits. When the apple trees are cultured indoors, the requirements of the apple trees are met regardless of the culture time and the culture conditions, and the growth, development and accumulated nutrition of the apple trees are not influenced.

(2) The method can greatly increase the yield of the plants, and does not influence the quality of the products: for peach trees, apricot trees and apple trees, fruits can be harvested only once a year after blooming and fruiting. Taking apple trees as an example, the method of the invention can be adopted, after the apple trees can blossom and bear fruits, the apple trees are carried to the outdoor after the fruits are harvested, the apple trees are dormant for 200 hours under the outdoor natural condition, then the apple trees are transferred to the indoor, and the fruits … … can be harvested after the apple trees are cultured for about 4 months under the growth and development conditions of spring, summer and autumn according to the growth and development requirements of the plants. Thus, within one year, the ripe fruits can be harvested for 2-3 times, and the yield of the fruits is greatly increased. When the apple trees are cultured indoors, the requirements of the apple trees are met no matter the culture time or the culture conditions, and the quality of the fruits cannot be influenced.

(3) According to the method, the dormancy stimulation does not have any adverse effect on the growth and development of the plants: at present, the plants can be promoted to enter the dormancy stage in advance by hormone stimulation or low-temperature stimulation, but the plants are forced to be dormant and are not naturally dormant. Hormone stimulation is used, and the dosage of the hormone, the dormancy time of plants and the resuscitation after dormancy are difficult to control; the low-temperature stimulation is carried out in the cold storage, the volume of the cold storage is limited, and the operation of personnel is not facilitated; the simulation of low temperature in the greenhouse is time-consuming and labor-consuming compared with the simulation of high temperature, and the consumed manpower, material resources and financial resources are high. In the method, the plants are dormant in the outdoor northern season, all conditions are natural, and the requirements of the plants on the dormancy conditions can be completely met; the outdoor space is bigger, can schedule at will, only need with the plant transportation to the north can.

(4) The method, the seedling raising mode and the transportation mode do not influence the original soil living environment of the plants: according to the seedling culture method, the seedling culture container can adapt to the whole process that the seedlings grow continuously from small to long, the problem of root injury of the seedlings cannot be caused when the container is replaced, and the seedlings do not need to be revived when the container is replaced. The nursery stock moves along with the original planting pot, so that the pollution of waste gas and garbage generated in the cultivation process to the environment is avoided; and the seedling raising pot and the growing pot are made of materials capable of automatically degrading, can automatically degrade and cannot cause harm to the environment.

(5) The method adopts the regenerated organic nutrient soil in the seedling raising process, the soil is recovered from brown coal mine wastes, the soil has the characteristics of air permeability, water retention, safety, cleanness and the like, and the wastes of the brown coal opencast ore are changed into valuables.
