Description

  The present invention shortens the period from growing seedlings to harvesting cherry peaches, and makes it possible to grow cherry peaches in small pots of No. 3 to No. 5 and the cherry peach seedling growing method and cherry peaches with flower buds The present invention relates to a method for growing hatched seedlings.

  The conventional method for growing cherry peach seedlings is to plant rootstocks for seedlings in the open ground and cultivate them for one year, then graft them on the rootstocks that have been cultivated for the past year, and then grow them by planting them in the ground. To do. In this seedling growing method, a rootstock cultivated in an open field by cutting is once dug up, and a large straight root is cut out and then grafted to nurture the seedling. Therefore, many fine roots are generated in grafted seedlings, and large and attractive seedlings can be produced. Therefore, conventionally, seedlings are mostly produced by this method.

However, with this seedling growing method, although the seedling grows greatly, it takes many years for the cherry peach to bear fruit, so the cherry peach cannot be harvested in a short period of time, and the seedling grows greatly. Therefore, there was a problem that it was not suitable for pot cultivation.
As a method for solving such a problem, the present applicant has proposed a cultivation method in which a cherry peach rootstock can be potted and the cherry peach can be harvested at an early stage (see Patent Document 1). This cultivation method is a method in which a cherry peach rootstock cultivated by cuttings is replanted in a pot, grafted on the rootstock, and a seedling is grown in the pot so that the cherry peach can be harvested. This method allows seedlings to be transferred to reproductive growth by growing seedlings in pots, thereby facilitating fruiting and enabling early harvesting of cherry trees.
JP 2002-65059 A

  In the case of the method of growing seedlings by the previous pot planting, it is necessary for one year to plant and cultivate the rootstock, and the cultivated rootstock is replanted in a pot, and cherry peaches are planted in the third year after grafting. Harvest. As described above, in the case of the conventional method of growing cherry sapling by potting, it takes four years from the cultivation of rootstock to harvesting cherry cherries. This potted plant has the advantage that it can harvest cherry peaches as early as 4-5 years compared to the conventional cultivation method using cherry peach seedlings, but the time (years) when cherry peaches can be harvested. If it can be further accelerated, the harvest efficiency of cherry peaches can be increased, and the hatching of seedlings can be promoted to handle ordinary households.

  The present invention has been made to solve these problems, it is possible to grow cherry peach seedlings in a short period of time, improve the efficiency of seedling growth, and by promoting the hatching of seedlings, To provide a method for growing cherry peach seedlings and a method for growing cherry peach dwarf seedlings with flower buds that can be easily handled in ordinary households as small potted trees and can be easily cultivated. Objective.

In order to achieve the above object, the present invention comprises the following arrangement.
That is, it is characterized in that a rootless seedling obtained by grafting a cherry tree to a rootstock of cherry peach is inserted into a seedling culture medium, and the seedling is cultivated with the seedling culture medium for one year. In addition, as the above-mentioned hogi, those having 1 to 2 leaf buds are used. In addition, after grafting the hogi to the rootstock, refrigeration for about one month and then cutting it, the hogi and the rootstock can be entrapped and reliably grafted.

  In addition, the cherry peach seedlings grown by the above method are replanted in pots the following year, and during the growth of the seedlings, all lateral branches other than the new shoots at the tip are pinched, and flower buds are formed on the new shoots and branches. It is characterized by being a cherry peach dwarf seedling with a mark. These seedlings with flower buds are provided as seedlings that can be blossomed the next year by potting or planting to harvest cherries.

  According to the method for growing a cherry peach seedling according to the present invention and the method for growing a cherry peach dwarfed sapling with a flower bud, by a method of growing a rootless seedling grafted to a root of a cherry peach rootstock by cutting, The cherry peach can be harvested in the third year after the start of growing the seedlings, and the period until the cherry peach is harvested can be shortened by one year compared with the conventional potted plant method. In addition, the seedlings are grown by growing them in a seedling culture medium and provided as seedlings that can bear fruit in the third year, so that the seedlings can be hatched and provided as small potted seedlings. This potted seedling can be provided as a suitable potted product that can harvest cherry cherries at home.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
(First year of seedling cultivation)
In the method for hatching and growing cherry peach seedlings according to the present invention, rootless seedlings obtained by grafting the saplings on the cherry peach rootstock are inserted into a seedling culture medium, and cultivation is started. FIG. 1A shows a state in which a seedling obtained by grafting a stock 22 to a rootstock 20 is directly inserted into a seedling pot 10 as a seedling container. For the rootstock 20, a rootstock for cherry blossoms such as Aobadai is used. For the hogi 22, an annual branch of only one or two buds with no flower buds is used. The one-year branch is the portion of the branch that stretched the previous year, cut from the cherry tree and used.

The rootstock 20 is grafted with a one-year branch, so it can be grafted more easily than when two-year and three-year branches are grafted, as in the conventional method of grafting the rootstock after grafting. Also gets higher.
The time for grafting is the spring after the dormant period of trees in the open-air cultivation. The dormant period is a period in which a certain number of days (hours) elapses below a certain temperature when the fruit tree is ripened. Cherry blossoms will not bear fruit until this rest period has passed. In the field-cultivated cherry peach, Nagano Prefecture is the southern limit where it can be cultivated stably. In warm regions, even during winter, the temperature does not fall below the temperature required for dormancy for a certain period of time, so the necessary dormancy period cannot be obtained. This is why cherry peaches cannot be cultivated in warm areas.
Cut the hotwood 22 from the tree after the dormant period has passed and graft it. When the scion 22 is cut out from a tree that has not been hibernated and grafted, the leaf buds are not enriched, so that the buds become worse.

  In addition, after grafting the hogi 22 to the rootstock 20, it is also effective to cultivate it by cutting it into a seedling container after refrigeration in the refrigerator for about a month. When the rootstock 20 is grafted with the hogi 22 and refrigerated for about one month, the rootstock 20 and the hogi 22 are settled and the failure when cutting is cut is reduced. The refrigerator temperature is about 5 ° C. Refrigeration of grafted rootless seedlings has the advantage that the required dormancy period can be ensured and cuttings can be cut early.

  In addition, when a seedling is inserted into the seedling pot 10 to grow the seedling, the growing is started so that the ear tree 22 does not start moving early. For this reason, it is good to start growing seedlings under a cold air environment, covering the nursery pot 10 with vinyl, and protecting the rootstock 20 from cold air. When raising seedlings in a house, the seedlings are planted in the seedling pot 10 for about three months, then transferred to an open field and grown in the seedling pot.

FIG. 1 (b) shows a state where the nursery pot 10 is grown until autumn in a state where a rootstock 20 obtained by grafting a scion 22 is inserted. The roots extend from the rootstock 20, the hogi 22 extends, and a number of leaf buds are formed.
In this way, a cherry peach seedling that has been cultivated for one year by cutting the grafted cherry peach is obtained.
In this embodiment, the grafting plant 10 is used as a seedling container to grow a graft. However, other seedling containers can be used in addition to the seedling pot.

(2nd year nursery seedling)
FIG. 2 shows a second year of growing seedlings. In the second year, seedlings grown for one year are taken out from the seedling container and replanted in pots. FIG. 2A shows a state in which a seedling is replanted in the pot 12 in the spring of the second year. The rootstock 20 and the hogi 22 are joined together. After planting in the pot 12, the tip 22a of the seedling is pruned, leaving 5-6 buds in the seedling.

FIG.2 (b) shows the state which grew the seedling in the pot 12 from the state of Fig.2 (a), and became autumn. Many roots grow from the seedling root 20a. The reason for growing the seedlings in the pot 12 is to suppress the region (range) in which the roots are extended by the pot 12 so that the seedlings can move to reproductive growth.
When growing a seedling from spring to autumn, only the shoot portion 22b is stretched and the lateral branch is pinched. The extended shoot 22b is pruned in winter. Three buds become flower buds 30 from the base of the extended shoot 22b. The position where the new treetop portion 22b is pruned is a position where one or two buds remain on the three flower buds 30.
The bud of the portion that was the seedling 22 becomes a cluster 32 in which flower buds and leaf buds are assembled. FIG. 2B shows a state in which about five clusters 32 are formed.

  Thus, in the second year after cutting, a cherry peach hatchling seedling with flower buds with clusters 32 and flower buds 30 in the state of FIG. 2B, that is, in a potted state, is obtained. The cherry peach seedlings with flower buds can be used as seedlings in potted or ground-planted conditions to harvest cherry cherries in the following year.

(Cultivation of cherry peaches 3rd year)
FIG. 3 shows the state of the third year after growing seedlings. FIG. 3A shows a state where clusters 32 and flower buds 30 are formed in the spring state of the third year. This potted tree can be grown in a house or open field, flowered and pollinated to produce cherries.
Depending on whether it is grown in a house or grown in an open field, the cherry ripens in two months after flowering. FIG.3 (b) shows the state where the cherry 40 became fruit on the cherry tree. There are about 5 flower buds in one cluster, and about 20 flower buds in one cluster and 3-5 fruits. As a whole, there are about 20 flower buds, so a total of about 30 cherries will bear fruit.
As shown in FIG. 3 (b), the cherry 40 is attached to the place where the cluster 32 is formed and the place where the flower bud 30 is formed on the tip side of the tree.

Thus, cherries can be harvested in the third year after cutting rootstocks grafted with cherry peaches on the seedling culture medium.
In cherry cultivation, cherries can be harvested by preparing a large number of potted cherry peach seedlings as shown in FIG. After harvesting the cherries in the third year, after growing the tree, just like pruning in FIG. 2 (b), the new tree portion may be pruned to prepare for flowering in the next year.
In the case of pot planting, house cultivation is easy, and there is an advantage that cherries can be provided earlier than outdoor cultivation.

  Apart from the method of flowering in the potted state shown in FIG. 2 (b) and harvesting cherries, the seedlings are planted in the third year from the state of FIG. It is also possible to harvest the cherries by fruiting. Once the tree has acquired the nature of reproductive growth, it will bear fruit every year from the following year, so the cherries should be harvested while gradually increasing the amount of cherries to be fruited.

The characteristic feature of the method for growing cherry peach seedlings and the method for growing cherry peach dwarfed seedlings according to the present invention is that a seedling obtained by grafting a cherry tree peach on a rootstock is directly inserted into a seedling culture medium to start growing. There is. According to the method of the present invention, cherry peaches can be harvested in the third year from the start of growing seedlings by cutting, and the period of time until harvesting cherries compared to conventional potted cultivation methods is 1 year. Can be shortened.
In addition, by cutting and growing the grafted seedlings, the trees can be hatched as compared to the case of growing by conventional pot planting, and the size is small (No. 3 (diameter 7.5 cm) to No. 5 (diameter 15 cm)) Cherry peach trees can be grown in pots. As a result, it can be provided as a mini pot in which cherry peach trees are potted, and can be provided as a potted product that can easily grow cherries even in ordinary households.

It is explanatory drawing which shows the spring state (a) and autumn state (b) which grafted the hogi to the rootstock and inserted it in the seedling pot. It is explanatory drawing which shows the state (a) of the spring after planting a seedling in a pot, and the state of autumn. It is explanatory drawing which shows the state (b) in which the spring state (a) of the 3rd year and the cherry were fruited.
