The present invention relates to a method for producing apple cider root stock, and more particularly, to an apple cider root stock production method capable of efficiently producing a good quality apple cider root stock at a low cost in a short time.

Apples are generally grown by grafting on large trees. In particular, a method of cultivating by grafting on a short dwarf tree is used. The grafting method using the dwarf tree has the advantage of increasing the yield of fruit in a short time and effectively managing the harvested fruit.

On the other hand, in order to increase the yield of apples, first of all, it is important to use good quality dwarf trees, and to produce good seedlings in order to use good quality dwarf trees.

As a method of producing seedlings, there are a double grafting method and a self-rooting method. The double grafting method is a method of producing seedlings by grafting dwarfized tree to general live tree, and then cultivating cultivated varieties back to dwarf tree. And the rooting method is a method of producing seedlings by grafting cultivated varieties to rooting roots by treating the dwarfized tree with cutting, burying, etc.

However, the double grafting method has the advantage of producing a large amount of seedlings having a dwarfing effect in a short period of time, but the length of the trees is produced differently, so that the degree of cultivation of cultivated varieties varies from tree to tree, and the degree of development or degeneration of real trees There is a disadvantage that the growth characteristics of the cultivated varieties are different depending on the presence or absence. Therefore, there is a problem that a good seedling cannot be obtained.

In addition, autologous tree planting has the advantage of being able to produce good seedlings, such as having roots, genetically stable, and obtaining a standard seedling having a constant length. However, seedling production and propagation through burying, tissue cultivation, etc. have a problem that it takes a lot of time, labor and cost.

The present invention has been made to solve the conventional problems as described above, the purpose is to produce seedlings through the arable land method, apple cider root production method that can efficiently produce a good quality of large stock quickly and efficiently It is about.

In order to achieve the above object, apple barley bark production method of the present invention, the method for producing apple barley bark, comprising the steps of: harvesting the cuttings from the mother tree; Treating the base of the collected incision to form root growth; Immersing the base of the insert into a rooting and disinfecting agent; Planting by inserting the base of the cutting into the top soil on the prepared cutting; Maintaining the top soil temperature at about 20 to 25 ° C. and the top soil humidity at about 70% while cutting the inside of the cutting chamber at 15 ° C. or less at daytime and 5 ° C. at night for rooting; Harvesting logs from the cuttings after 20 to 40 days; It characterized in that it comprises the step of planting the rooted roots in the formal packaging.

Preferably, at the time of harvesting the insert, the young branches of either M.26 or M.9 are harvested in a thickness of about 6 to 13 mm and a length of about 40 to 50 cm.

And the step of processing the base of the cutting is characterized in that any one of peeling 2-3 places around the base of the cutting or wounding of two to three eyes around the base.

And in the step of planting large trees in the formal packaging, the M.9 large tree is planted between April 5 to April 10 in about 20 days after cutting, and the M.26 large tree is 30 to 40 days after cutting It is characterized in that the formality between April 20 to April 30 in the degree.

And in the step of planting the cuttings on the cuttings, characterized in that the bundle is planted in bundles of 10 each, the step of immersing the base of the cuttings in rooting and fungicides, the base of the cuttings 5 seconds to the rooting After immersion, the sterilizing agent is characterized in that it is immersed after 30 seconds.

Before dipping the base of the insert into rooting and disinfecting agents, IBA (β-indolebutyric acid) solution was diluted in distilled water at a concentration of 2,500 ppm to prepare a rooting agent, and hexaconazole was diluted in distilled water at a concentration of 50%. It characterized in that it further comprises the step of preparing a fungicide.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the apple barley root production method according to the present invention will be described in detail.

Figure 1 is a block diagram showing each step of the apple barley bark production method according to the present invention, Figure 2a to 2h is an exemplary view showing briefly each step of the apple barley bark production method according to the present invention.

First, referring to Figure 1, apple cider root production method of the present invention, the step of cutting the cuttings, that is, young branches from the tree (hereinafter, abbreviated as "mother tree") that is the parent of the tree ( S101). At this time, as shown in FIG. 2A, it is preferable to collect the young eggplant of about 6-13 mm in thickness by about 40-50 cm in length. The base 12 is preferably cut at an angle in an oblique direction. In addition, it is preferable to select the mother tree as Dwarf saengmyeong (M.26), the extreme outside life (M.9).

On the other hand, the insert 10, it is good to collect and recycle the cut off to grafting. In this way, by collecting and recycling the closed compounds, it can be expected to reduce the cost.

And the method for producing the large tree of the present invention, as shown in Figure 1, further comprises the step (S103) of cold storage the collected insert as needed. The low temperature storage step (S103) must maintain the conditions of temperature -0.5 ~ 0.5 ℃, humidity 90 ~ 95%. In some cases, it may be sealed and stored in vinyl.

This low-temperature storage step (S103), it is possible to store and store the collected cuts for a long time, and thus can use a good cuts when necessary.

Again, referring to Figure 1, the method for producing a large tree of the present invention includes the step of forming a cutting room (S104). The cutting room is a place for installing a cutting phase to be described later. As shown in FIG. 2B, it is preferable to form the cutting room 40a having a half-dark room by installing the vinyl house 40. Of course, it is also possible to form a cutting room in a separate warehouse instead of a plastic house.

On the other hand, in the case of installing the vinyl house 40, covering the insulating cover 42 of the fiber material on the upper surface of the vinyl house 40, the light shielding film 44 having a light shielding degree of 90% again on the upper surface of the insulating cover 42 It is good to cover. This is to make the cutting room 40a in the condition of the half dark room.

Again, referring to Figure 1, the method for producing a large tree of the present invention includes a step S105 of preparing a seedling for cutting, that is, cutting for cutting.

The cutting step (S105), as shown in Figure 2c, after preparing the frame 20 of the horizontal (L) 500cm, vertical (W) 120cm, height (H) 30cm, and then of the prepared frame 20 Lay down the styrofoam sheet 22 on the inner bottom surface, the Masato 24 is laminated on the styrofoam sheet 22 to a thickness of 5 cm, and the heating wire 26 is again arranged on the laminated Masato 24, and finally, This has a configuration in which the topsoil 28 is laminated again. Here, the topsoil 28 is any one of vermiculite, masato, and sand, and the lamination thickness at this time is preferably set to approximately 20 cm.

On the other hand, when the cutting production step (S105) is completed, as shown in Figure 1, and includes the step (S107) of processing the base of the collected cut water.

Insertion part processing step (S107) is, as shown in Figure 2d, around the base 12 of the insert 10, about 2 to 3 places of peeling (12a) of about 1 cm in the longitudinal direction or around the base 12 It is a step of hurting two to three eyes 14.

This cutting part processing step (S107), by forming a peeled portion on the base 12 of the insertion (10) or by forming a wound on the eye 14 to make a root growth, when cutting, that is, cutting ( When the base 12 is inserted into the tops 28 of 30, callus is formed in the skin or wound (root growth) of the base 12 so that roots can grow. On the other hand, the inserts are managed in bundles of 10 so that they can be easily managed after the base treatment.

Again, referring to Figure 1, the method for producing a large tree of the present invention, during the process of inserting the base material, prepare a rooting agent and a fungicide (S109).

Rooting agent and disinfectant manufacturing step (S109), by diluting a high concentration of the rooting promoter in distilled water to prepare a rooting agent and at the same time is prepared by diluting the disinfectant in distilled water or water. Here, it is preferable to use a hormone of auxin system, for example, IBA (β-indolebutyric acid) solution as the rooting promoter, and at this time, the IBA solution is preferably diluted to a concentration of 2,500 ppm in the distilled water. In addition, it is preferable to use hexaconazole as a fungicide, in which case hexaconazole is preferably diluted to a concentration of 50% in the distilled water.

On the other hand, when the preparation of the rooting agent is completed, the base of the insert is immersed in the manufactured rooting agent for a predetermined time (S111), and after a predetermined time, it is immersed again in the disinfectant and insecticide (S113). At this time, the insertion is preferably immersed in the rooting agent for about 5 seconds, and then immersed again in the disinfectant after 30 seconds.

In this way, the insertion efficiency immersed in the rooting agent increases the rooting efficiency at the peeling part or the wound part as much as possible. In addition, the inserts immersed in the disinfectant prevent prevention and rooting from various diseases.

And when the treatment of the rooting agent and the disinfectant is completed, the step of inserting and inserting the treated cutting in a bundle tied to the cutting (S115). At this time, as shown in Figure 2e, it is preferable that the cutting is inserted into the top soil 28 of the cutting 30 to a depth of about 15 to 20 cm.

On the other hand, when the cutting of the cutting is completed, the temperature of the top soil 28 of the cutting 30 on which the cutting 10 is planted is maintained at about 20 to 25 ° C, and the humidity of the top soil is about 70%, and the cutting phase 30 is It includes the step (S119) of maintaining the internal temperature of the cutting room 40a accommodated at about 15 ° C. or less at daytime and about 5 ° C. at night.

The reason for keeping the top soil 28 temperature of the cutting wood 30 at 20 to 25 ° C. is to create a relatively high temperature condition on the base 12 of the insert 10, which is planted in the top soil 28, so that This is to increase the rooting efficiency in the wound area as much as possible.

The reason for keeping the internal temperature of the vinyl house 40 at 15 ° C. during the day and 5 ° C. at the night is that a relatively low temperature condition is formed in the “eyes 14” of the upper part of the insert 10 so that the “ This is to suppress the germination of the eyes 14 "as much as possible.

1 and 2F, after approximately 20 to 40 days have elapsed in a state in which the internal temperature of the cutting chamber 40a and the temperature and humidity of the top soil 28 of the cutting bed 30 are properly controlled, In step S121, the cutting insert 10 is collected from the 30.

In this step, by extracting the insert 10 from the cutting phase 30, as shown in FIG. 2G, the large tree 50 in which the root 52 is formed can be produced.

On the other hand, when the sampling of the large tree 50 is completed, further comprising the step (S123) of planting the collected large tree 50 in the formal packaging. Formal packaging is a step of coating the white vinyl 60 on the formal packaging mockup, as shown in Figure 2h and planting the trees 50 collected on the vinyl one by one.

At this time, it is preferable that the M.9 tree is planted about 20 days after the cutting, and the M.26 tree is about 30-40 days of cutting, and the timing of the M.9 tree is the beginning and the middle of April, that is, April 5 Between April 10 and April 10, M.26 stocks had a high sticking rate in mid and late April, that is, between April 20 and April 30. This is because the formal packing can be increased only when the geothermal temperature of the formal packaging is higher than 15 ℃.

Seedlings produced through various steps as described above, as well as having the roots as described above, the number and growth of the roots are very excellent. In addition, the length is constant, it can be a good quality of big tree.

The present inventors produce seedlings according to the production method of the present invention, but different cutting period, top soil, and planting roots according to the rooting rate and the number of roots (root number), root length (root length), pavement sticking rate (root at very planting) Down). The results are shown in the following [Table 1] to [Table 3].

As shown in Table 1, the root growth rate and pavement sticking rate by soil and tree when the cutting period was set to 20 days, the rooting rate was more than 90% for vermiculite, masato, sand and M.9, M.26. Root length (root length) and root length (root length) were more than 1.8 and 0.4 mm in vermiculite, masato, sand, and M.9 and M.26 trees. In addition, the pavement sliding rate of M.9 trees was higher than M.9 trees.

As shown in Table 3, when the cutting period was set to 40 days, the root growth rate and pavement sticking rate by soil and tree were found to be over 95% regardless of soil and plant. The number of roots in M.26 was longer than that in M.9, but the root was longer in M.9 than in M.26. The pavement sliding rate of M.26 trees was higher than 80% regardless of soil, and M.9 trees were rapidly lowered to 40%.

Taken together, the rooting rate by soil and tree was excellent in vermiculite, masato, sand and M.26 and M.9. Logistics and root length were also slightly different, but vermiculite, masato, sand, and M.26 and M.9 were all excellent. When the cutting period was about 20 days, enough roots were formed to grow. Therefore, the cutting period was about 20 to 40 days.

At this time, the M.9 stocks have a high packing sliding rate at 20 days of cutting, so it is better to pack them 20 to 30 days before cutting. Since it shows, 30-40 days before the cutting is recommended to formally pack.

Next, the present inventors produced seedlings by the production method of the present invention, the thickness of the cutting was different and compared with each other the rooting rate and root number (root number), root length (root length), pavement sliding rate. The results are shown in [Table 4].

As shown in Table 4, the rooting rate was 90% or more in both M.9 and M.26 trees when the thickness of the cut was about 6-11 mm. The number of roots (9-12) was the highest when the number of cuts in the M.9 and M.26 trees was more than 11 mm thick. The root length was found to be the longest (23-28 mm) when M.9 and M.26 trunks were between 6 and 8 mm thick. And the packing sliding rate was found to be high when the thickness of the insert is 9mm or more.

As a result, when the thickness of the insert is between 6 and 11 mm, the rooting rate is the best, the root number and root length are also very large and grow long, and the pavement sliding rate is also satisfied. Therefore, it is best to collect an insert with a thickness of about 6 to 11 mm.

Next, the present inventors prepared seedlings by the production method of the present invention, and the base treatment of the cuttings were different, and the rooting ratio and the root number (root number), root length (root length) and pavement sliding rate were compared. The results are shown in [Table 5].

As shown in Table 5, the rooting rate was greater than 90% in both M.9 and M.26 trees when cutting the base of the incision, cutting the skin, and hurting the eyes. Logistics was also found to occur a large number (7-14) when peeling the base or hurt the eye of the base. And roots were found to be the longest (24 ~ 30㎜) when cut the base. The pavement sliding rate was 70% or more in both M.9 and M.26 cases when cutting, peeling, and eye damage were made at the base of the insert.

As a result, when cutting the base of the cutting and coating or cutting the base of the cutting and wounding the nearby eyes, the rooting rate is the best, the root and root length is very large, long growth, and the pavement sticking rate is also very good. have.

Therefore, it is desirable to choose either to cut and coat the base of the cut, or to cut the base of the cut and to injure nearby eyes.

Next, the present inventors prepared the seedlings by the production method of the present invention, by comparing the time and the formal packaging time of the cuttings to each other and compared the packing slip rate accordingly. The results are shown in [Table 6].

As shown in Table 6, in the case of M.9 stocks, pavement sliding rate of 82 ~ 85% was found to be higher than 20 ~ 20%. In the case of M.26 trees, pavement sliding rate was very high (more than 90%) when the planting time was set in mid and late April around 30 days.

As a result, the formal packing time of large trees should be about 20 days after cutting, for M.9 large trees, but between the beginning and mid April, i.e. between April 5 and April 10. In the case of M.26 trees, it is recommended that they are about 30 to 40 days after cutting, but in mid- or late April, that is, April 20 to April 30.
