Description

  The present invention relates to grafted seedlings, which is a kind of vegetative propagation method performed in horticultural plants such as fruit trees and flowering trees. The present invention relates to a method for producing grafted seedlings by rooting trees or cuttings.

  Conventionally, the propagation of plants such as fruit trees has been mainly vegetative propagation by grafting, cuttings or cuttings from the viewpoint that clone seedlings having the same shape and properties as the parent tree can be obtained and desirable varieties can be increased as they are. . In general, when you want to increase the number of seedlings, it is the order of cuttings, grafts, and cuttings, and it is the order of cuttings, cuttings, and grafting that has few failures. It is said to be in the order of grafting and cutting. Cuttings can produce a large number of seedlings at once, but because the seedlings are small, it takes time to become mature trees, and varieties with weak roots have problems such as soil maintenance and management etc. . Torigi has larger seedlings than cuttings, but it cannot make many seedlings at the same time as cuttings.

In addition, depending on the rootstock, depending on the rootstock, the grafting may cause problems depending on pests and soil conditions. However, high quality can be achieved by grafting on rootstocks that are resistant to pests and soil conditions. There is an advantage that the labor of management can be reduced even for the variety. As one example of this, grafting breeding methods using blueberries as hogi and Japanese native rhododendron genus genus shachambo adapted to Japanese soil as a rootstock have been published as a prior art, and compared with conventional methods of growing by cutting seedlings The tree grows quickly and can be harvested early (Reference 1).

  As mentioned above, it is easy to renew the parent tree by obtaining the grafted seedlings by grafting the ears of the parent tree with the desired quality against pests and grafting on the rootstock seedling suitable for the cultivation soil. Although it is excellent in that it can be done, it is necessary to grow from seedling seedlings and cutting rooting seedlings to secure rootstock seedlings, so it takes a long time to grow into rootstock seedlings, and in turn, grafted seedlings It took a long time to produce. In addition, there is a problem that it is difficult to multiply a large amount of grafted seedlings from the rootstock because it is difficult to easily obtain a large amount of grafted seedlings due to restrictions on the place where the rootstock is grown and manpower.

  The present invention relates to a grafted seedling that is a kind of vegetative propagation method performed in garden plants such as fruit trees and flower trees, which has been completed by repeated trials in order to solve the above-mentioned problems. By grafting the parent tree, which grows on the young branches of the tree, and rooting it by cutting or cutting, it is possible to obtain a grafted seedling that is durable and easy to grow in a shorter period of time, The present invention provides a production method for obtaining grafted seedlings having the same characteristics in large quantities at a time.

  In order to achieve the above object, a method for producing grafted seedlings according to claim 1 of the present invention takes a tree at a plurality of locations of a shoot of a rootstock, and a parent tree on the front side of the location of the tree The plant is characterized in that a plurality of grafted seedlings are obtained by cutting from the rooted root portion of the rootstock to which the hogi is grafted by cultivating the shoots or branches.

  The method for producing the grafted seedlings is a method in which cuts are made in the middle of the young branches as rootstocks, and buds cut from the parent tree to be propagated or renewed or ears cut from several shoots from one shoot. A tree is grafted to a cut of the rootstock by grafting or branching, and at the same time, by cutting the rootstock from the grafted portion at the base of the branch, the hogi is grafted to the rootstock and the rootstock is removed. After growing by rooting from the xylem, cutting from the harvesting part is performed to obtain a grafted seedling in which the parent tree is grafted to the rootstock and rooted from the rootstock.

  According to this method, even if it is a plant that is a parent tree and is difficult to root by cutting, the parent tree surely settled on the rootstock by using both grafting and harvesting, and rooted firmly from the rootstock A strong grafted seedling that is easy to grow into an adult can be obtained. Also, according to this method, since the parent tree is touched at the time of harvesting, the root part of the rootstock is used to touch the parent tree as in the conventional method using rootstocks grown from seedling seedlings or cutting rooting seedlings. Since it is not necessary to cut down nearby, the growing period of the rootstock that was cut off by the conventional method can be applied to the growing period of the parent tree, so it is possible to grow the growing period of grafted seedlings into mature trees and increase them greatly. In the type of obtaining fruit, it can be harvested early.

Further, this method is obtained by growing a plurality of grafted seedlings almost simultaneously by grafting and harvesting at a plurality of positions on the young branch. In addition, according to this method, a large amount of grafted seedlings can be produced, and grafted seedlings derived from the same rootstock can be obtained. Therefore, characteristics such as growth conditions, adaptation to the environment and resistance to pests tend to be the same. Easy to manage cultivation.

  The method for producing grafted seedlings according to claim 2 is the method for producing grafted seedlings according to claim 1, wherein the synthetic resin or non-woven fabric grafting pot used for harvesting has a substantially conical shape with an upper end opened. A cylindrical pot body, a pot bottom plate provided with a young branch insertion hole in the center, a single notch provided from the upper end of the pot body to the insertion hole of the pot bottom plate, and the pot with the cut as a boundary From the two velvet portions that bulge out the outer diameter of the main body, a plurality of banding band holes and a plurality of water passage holes provided in the upper part of the pot body, and a water passage hole provided in the pot body The pot body is configured by squeezing the upper part of the pot body by wrapping along the pot body with the two velocities overlapped with each other and squeezing the binding band through the binding bands. Drawstring Wherein the allowed formed Jo.

Since this production can be integrally molded by blow molding or the like, it can be mass-produced and is economical. In addition, in the case of non-woven fabric pots, it is possible to manufacture by integrally molding from a non-woven fiber sheet, and the material itself is breathable and water permeable. It is not necessary to consider the position of. In addition, because it has biodegradability, it can be said that it is environmentally friendly even if planted.

  The method for producing grafted seedlings according to claim 3 is a method of grafting by grafting or cutting branches of a parent tree at a plurality of locations of young branches of an adult tree that becomes a rootstock, and cutting and cutting after planting. It is characterized by obtaining a plurality of grafted seedlings by rooting.

  According to this method, even in the case of a parent tree of a variety that is difficult to root with cuttings, the roots of the parent tree are easy to root, suitable for cultivated soil, and resistant to pests of rootstock. After grafting the tree, the rootstock settled by the hogi is cut out and cut into cuttings to produce grafted seedlings.The grafted seedlings can be planted and planted and grown on the mature tree easily and reliably. it can. In addition, by grafting the parent tree's spikes at multiple locations on the young branch, a large number of grafted seedlings are finally obtained almost simultaneously, so the parent tree can be propagated or renewed many times at a time. Improves. In addition, according to this method, a large amount of grafted seedlings can be produced, and grafted seedlings derived from the same rootstock can be obtained, so the characteristics of rootstocks such as growth condition, adaptation to the environment and resistance to pests tend to be the same. Therefore, cultivation management is easy.

  According to the method for producing grafted seedlings according to claim 1 of the present invention, if conventional grafting breeding, the period for growing and managing rootstock seedlings from seedling seedlings and cutting rooting seedlings is as long as 2 to 5 years. Compared to what is required, the method of the present invention allows the grafting part to be rooted and the rooting part to be rooted at the same time, so that the growing period of the grafted seedling can be shortened to 1 to 2 years, and these operations can be shortened. Can also save labor. In addition, since large grafted seedlings can be produced compared to the conventional cutting method, it is possible to renew the parent tree, which is an excellent variety, in a short period of time, and it is possible to quickly produce high value-added fruits and the like. In addition, according to this method, a large amount of grafted seedlings can be produced, and grafted seedlings derived from the same rootstock can be obtained, so the characteristics of rootstocks such as growth condition, adaptation to the environment and resistance to pests tend to be the same. Therefore, cultivation management is easy.

In addition, according to the pot for taking wood according to claim 2, it is easy to use granular soil such as red jade soil and kanuma soil with good air permeability and drainage for the upright, diagonal and side branch branches. It is easy to root and can be replanted as a grafted seedling after the amount of roots has increased sufficiently. In addition, since the same soil can be replanted at the time of replanting, the work is easy, and damage to the root portion at the time of replanting can be reduced, so that the grafted seedlings can be well laid. In addition, synthetic resin or non-woven fabric wood-making pots can be manufactured at low cost, wood-making work, the wood-making pot of the present invention has a simple structure, and the tool is a binding band, stapler, firewood, etc. Therefore, the operation can be simplified at low cost.

  Further, according to the method for producing grafted seedlings of claim 3, since the parent tree is touched at the time of cutting, in order to touch the parent tree as in the conventional method using rootstocks grown from seedling seedlings or rooted seedlings of cuttings Since it is not necessary to cut off the root part of the rootstock near the root, the growing period of the rootstock cut off by the conventional method can also be applied to the growing period of the parent tree, so the period for growing grafted seedlings to adult trees is short and large. It can be grown and can be harvested early on in the fruit-producing varieties. In addition, since many grafts derived from rootstocks of the same nature can be cultivated at a time, productivity is high in the propagation or renewal of the parent tree, the work efficiency is good, and the economic effect is great.

FIG. 2 (a) schematically shows grafted seedling 1 produced by this method, in which a parent tree 3-1 is branched into rootstock 10 and the rootstock is cut by the tree. This is a grafted seedling 1 having a rooting part 12 rooted from 10 before planting. Moreover, although the example which applied the pot 6 for taking a tree is shown in the taking tree, the method of wrapping the soil 72 or the sphagnum with the conventional method of wrapping with sphagnum or a vinyl sheet can also be taken. Further, in the method using the tree pot 6, the weight of the plurality of tree pots 6 acts as a load on the shoot 2, so it is desirable that the support is supported by the support 7 so that the shoot 2 does not bend.

  The above-mentioned grafting tree 3-1 used for grafting cuts off a branch with several buds from one bud from the parent tree to be propagated or renewed, and branches the grafted part to the grafted part 3 of the young branch 2 of the rootstock 10. Processed as possible to obtain Hogi 3-1. FIGS. 1 and 2 show an example of branching Hogi 3-1, but instead of the branch, a portion having a bud is scraped off from the parent tree, and a portion with a bud is sprouted as Hogi 3-1. Grafting methods can also be used. In addition, in order to ensure grafting, the rootstock 10 is preferably selected from a species close to the parent tree. In addition, the rootstock 10 is suitable for soil in which the grafted seedling 1 is grown and then planted, and is resistant to pests. It is better to choose some sort of thing. Also, the young branch 2 of the rootstock 10 and the hogi 3-1 of the parent tree grow well, and it is better to use young branches of a young, vigorous strain, and as thick and solid as possible.

  FIG. 1 (b) shows a method for producing a grafted seedling 1 by grafting / cutting. In a plurality of locations of a young branch 2 of a rootstock 10, a grafted portion 3 that branches a parent tree 3-1 at each location is shown. It is the figure which is provided, and is the state of the state which makes the cutting head 11 in the stage before cutting for producing the graft seedling 1. That is, if the hogi 3-1 is settled on the young branch 2 by grafting, the young branch 2 is cut on the branch base side of the graft portion 3, and the cut portion is processed to insert the ear 11. FIG. 2 (b) shows the cutting head 11, and the cutting head 11 is cut and rooted in the soil 72 in the growing pot 73, and the rooting is performed as shown in FIG. 2 (c). The grafted seedling 1 having the rooted part 12 is produced. In this case, it is also possible to use a grafting method in which a portion having a bud is scraped from the parent tree instead of a branch and a portion having a bud is sprouted as a hot tree 3-1. In addition, both the young branch 2 of the rootstock 10 that becomes the cutting head 11 and the hot tree 3-1 of the parent tree grow well, and it is preferable to use the young branch of a vigorous young strain. In addition, in order to reliably graft the rootstock 10, it is preferable to select a species close to the parent tree. In addition, the rootstock can be reliably rooted with cuttings and easily grown as a grafted seedling 1, and thereafter It is recommended to select a species that is suitable for the soil to be planted and is resistant to pests.

  The harvesting pot 6 used in the method of producing the grafted seedling 1 by grafting and harvesting will be described with reference to FIG. 3. The harvesting pot 6 includes a substantially conical cylindrical pot main body 60 having an upper end opened, and a center. A pot bottom plate 61 provided with an insertion hole 67 in the section, a notch 62 provided from the upper end of the pot body 60 to the insertion hole 67 of the pot bottom plate 61, and the outside of the pot body 60 with the notch 62 as a boundary. Two velvet portions 63 projecting with an enlarged diameter, a plurality of binding band holes 65 and a plurality of water passage holes 66 provided at the upper portion of the pot body 60, and a water passage hole 66 provided in the pot body 60 It is comprised integrally from. It is necessary to prepare several types of the pots 6 for harvesting according to the young branches 2 to be harvested. Specifically, the pot size is 1 (diameter 3 cm), 2 or 3, It can cope with 5 size of No. 4, 5 (diameter 15cm). Moreover, since the pot 6 is fixed by a binding tool 71 such as a binding band 70 and a stapler, the material of the pot 6 for taking wood is preferably a thin and soft synthetic resin such as vinyl or plastic, or a non-woven fabric. The synthetic resin is desirably manufactured from a plastic material having sufficient strength and elasticity to some extent even if it is thin, and is integrally manufactured by a molding process such as blow molding. As this plastic material, inexpensive plastics such as vinyl, polyethylene and polypropylene are suitable. Moreover, the said nonwoven fabric can be manufactured by shape | molding integrally from the nonwoven fiber sheet using a natural fiber. From the viewpoint of the environment, biodegradable plastics that can be planted as they are and nonwoven fabrics using natural plant fibers are also suitable.

  3 and 4, the portion 63 of the young branch 2 to be taken, for example, the annular peeled portion 4 is taken into the pot 6 through the insertion hole 67, and then the notch 62 is sandwiched. Then, the two bellows 63 are overlapped so as to be wound along the pot main body 60 and fastened with a binding tool 71 to assemble the pot 6 for harvesting, and then the soil 72 is surrounded by surrounding the young branch 2 and the annular peeled part 4. In this case, the overhang of the tongue portion 63 is prevented so that the soil 72 does not spill and the pot body 60 does not break or tear from the cut 64 where the tongue portion 63 overlaps. The length is determined in consideration of the size of the pot 6 for taking wood.

  Regarding the binding band hole 65, the binding band 70 is attached to the pot body for the tree cutting pot 6 in which the annular skinned portion 4 of the young branch 2 to be trimmed is taken in and surrounded by the soil 72. 60 is tightened by passing through a bundling band hole 65 provided in the upper portion, that is, is narrowed down to form a drawstring-shaped lumbering pot 6 that is broken from the narrowing guideline 68. It is preferable to determine the size and the number of the binding band holes 65 in accordance with the size of the binding band 70 so that no wrinkles or wrinkles are generated. The width of the binding band 70 is usually in the range of 5 to 10 mm, and the number of the binding band holes 65 is in the range of 6 to 12 although it depends on the size of the lumber pot 6.

  In the above-described drawstring-shaped lumber pot 6, the upper portion of the pot body 60 covers and closes the opening of the pot 6, thereby preventing the wet soil 5 from being dried. In addition, the plurality of water holes 66 provided in the upper portion of the pot body 60 allow water to reach the pot 6 when the pot 6 is watered to prevent stuffiness and supply water and nutrients to the pot 6. It plays the role of a water hole. The bottom plate 61 shown in FIG. 4B is provided with an insertion hole 67 through which the young branch 2 to be taken through is taken into the pot 6, and an insertion hole having a size corresponding to the thickness of the young branch 2 to be taken in. In order to facilitate processing with a scissors or the like, an insertion hole guideline 69 with some streaks such as annual rings indicating dimensions is provided.

  Further, the color of the pot 6 for taking wood is a color that does not transmit light so that the rooting becomes natural, for example, black is effective at a low temperature because it easily absorbs solar heat, and the silver color reflects light. Therefore, since the temperature in the pot 6 is less likely to be higher than that of black, it is effective when the temperature is high. Moreover, what is necessary is just to have the transparent color which can see the dry condition including the soil in the pot 6, and a rooting state, and can be suitably selected according to a user's purpose and use in this way. In the case of a non-woven fabric, it can be appropriately selected from black and white that does not easily rise in temperature.

  As shown in FIGS. 3 (a) and 3 (b), a young tree 2 standing upright using a tree-making pot 6 made of synthetic resin in a tree-making pot 6 (hereinafter referred to as pot 6) according to the present invention. The embodiment applied to the above will be described. First, the bark is peeled off in an annular manner from the portion of the young branch 2 to be cut to form the annular peeled portion 4. Next, the inner diameter of the insertion hole 67 is adjusted in accordance with the guideline 69 of the bottom plate 61 so as to match the thickness of the young branch 2 taken into the pot 6. Next, the notch 62 that extends from the upper end of the pot body 60 to the insertion hole 67 is expanded so that the young branch 2 and the annular peeled portion 4 are fitted into the insertion hole 67 and taken into the pot 6. Next, the notch 62 is returned to the original position, and the two tongue portions 63 are overlapped so as to be wound along the pot body 60 and are fastened with the binding tool 71 to assemble the pot 6. Next, the soil 72 (or sphagnum) is loaded so that the shoot 2 in the pot is buried around the portion of the annular peeled portion 4. In the case of sphagnum, the root and sphagnum entangle each other when the amount of roots increases, and it is difficult to remove the sphagnum.

  Next, the pot 6 is pulled by tightening the binding band hole 65 in the upper part of the pot body 60 of the pot 6 in which the annular peeled portion 4 of the young branch 2 to be trimmed is buried with the soil 72 through the commercially available binding band 70 made of vinyl. The pot body 60 is installed and fixed on the branch 2, and the upper portion of the pot body 60 is folded and narrowed from the guideline 69 to close the opening of the upper portion of the pot body 60, thereby forming the purse-shaped pot 6. At this time, as shown in FIG. 3B, when forming a purse-shaped pot 6 in which a portion of the water passage hole 66 in the upper part of the pot body 60 is depressed, water is poured into the pot 6 when watering. Easy to ooze. At this time, care should be taken that the upper portion of the pot body 60 prevents excessive wrinkles and wrinkles from occurring so that the subsequent watering can be evenly distributed in the pot 6. Further, as shown in FIG. 3B, in order to prevent the pot 6 from sliding down, another tie band 70 is fixed to the young branch 2 at the time of the insertion hole 67 in the bottom plate 61 of the pot 6, It is preferable that the surplus portion of the binding band 70 is put on the bottom plate 61 of the pot 6.

  As described above, when a tree pot 6 is installed on the shoot 2 to be harvested and moisture is appropriately used, adventitious roots (not shown) are rooted from the annular peeled portion 4 that is the tree portion. Continue to grow. In this way, when it is time to determine that the planting will be done even after replanting, the pot 6 for cutting trees is separated for each young branch 2 and replanted as a grafted seedling 1 for each pot 6, or the pot 6 is removed from the outline. The root can be planted with soil. Even in the former case, when the root develops, the binding tool 71 such as a stapler that holds the tongue 63 of the pot body 60 is released by the force of the root, and the pot body 60 is easily broken. It is integrated with the soil for planting and does not hinder the growth of the grafted seedling 1. Therefore, both replanting operations are simple and have a high probability of success in planting if the pot 6 for harvesting of the present invention is used.

  FIG. 3 (c) shows an application example of the tree-planting pot 6 for the slanted shoot 2 but is the same in the case of a horizontally-oriented branch, and is different from the upright branch tree below. Only will be described. In the case of an oblique or sideways branch, the work is performed in the same manner as in the case of an upright branch. However, if the direction of the pot 6 is fixed so that the line of the cut 64 around the tongue portion 63 is upward, the pot 6 is used when watering. Water easily penetrates into the inside. In the case of landscape orientation, when the pot body 60 is formed with a binding tool 71 such as a stapler, the pot 72 is passed through the binding band 70 and the opening 72 of the pot body 60 is squeezed into the soil 72. The work for charging the soil 5 becomes easy.

  In the case of the non-woven fabric pot 6, the material of the pot 6 itself has air permeability and water permeability, so there is no need to make the direction of the cut 64 of the pot body 60 upward. Further, since the pot 6 is weak, it is difficult to load the soil 72 compared to the pot 6 made of synthetic resin. However, it can be improved if it is lined with a binding band 70 before the soil 72 is inserted.

  In the field of vegetative propagation of trees such as fruit trees and flower trees, it can be used for propagation of the trees using mass-produced grafted seedlings.
