Description

  The present invention is a one-step dense planting cultivation of tomatoes that is produced by growing only the first inflorescence of the first inflorescence, allowing each of the flowers constituting the inflorescence to bloom, and then harvesting the fruits by pollination of each flower. It is about the method.

Tomato cultivation is generally carried out by planting seedlings that have been sown and planted at intervals of 30 to 50 cm with the first inflorescence oriented in the same direction, and then 6 to 12 stages in the vertical direction by cultivation for about half a year. Each flower floret is allowed to grow and each flower constituting the flower floret is opened, and then fruit is produced by pollination of each flower. In this way, fruit is produced from the flowers constituting each stage of the bunches, whereby fruit bunches of 6 to 12 stages, each of which is an aggregate of fruits, are formed. It is done by growing and harvesting the fruits that make up the bunches.
Among them, as a method for cultivating tomatoes, a so-called long set-up in which fruit is harvested over a year by growing flower bunches of 20 to 30 stages and growing fruit bunches in the same manner as described above. There is also a technique called.

  However, cultivation of tomatoes for harvesting 6-30 stage fruits as described above is difficult to manage for stable maintenance of the tree for a long period of time. In addition, there is a problem that the quality is deteriorated and there is a risk that if the pests spread during cultivation, there is a risk that cultivation cannot be continued, so that periodic control is necessary. In addition, there is a drawback that the work at a high place is increased by the increase in the number of stages of fruit bunches.

  On the other hand, as a method for cultivating tomatoes, although there is one-stage dense planting that allows only one stage fruit bunches that are easy to grow, the one-stage dense planting has a short cultivation period of about 1 to 3 months. Therefore, it is necessary to increase the number of plantings and the number of plants per crop in order to produce the same number of fruits as in the case of 6 to 30 stages, and a large amount of seedlings are required regardless of the season. For this reason, in particular, it is difficult to raise seedlings in the high temperature period and the low temperature period, and the cost increases for growing a large number of seedlings. Therefore, this one-stage dense planting cultivation has not been used.

  However, in recent years, the present inventors have developed a seedling production apparatus using an artificial lighting device that enables the growth of rootstocks and ears and the curing of grafted seedlings, as shown in Patent Document 1, It has made it easy to produce seedlings throughout the year, and has made it possible to reduce initial costs and running costs. As a result, the use of this one-step dense planting of tomato has become realistic.

  However, in the one-stage dense planting of tomatoes, in order to plant seedlings at a narrow interval, as shown in FIG. 3, not only the branches 11, 12, 13 above the first inflorescence but also the branches 11 of the adjacent main stem 4. , 12 and 13 cover the flower bunches and the fruit bunches 10 on which they grow and the sun shines on the fruit bunches 10 or the like. As a result, fruits such as increase in hollow fruits, increase in streak fruits that cause black streaks in the vascular bundle inside fruit 7, decrease in color gloss of fruit 7 and decrease in sugar, vitamin and acid content of fruit 7 There is a problem that quality deterioration can be caused. Furthermore, in one-stage dense planting of tomatoes, in addition to the above-mentioned deterioration in the quality of the fruit 7, there is a problem of a decrease in the number of fruits to be shipped due to fruit drop such as fruit dropping during the cultivation and a mildew disease, and an increase in the shade of the fruit 7 There is also a problem of prolonged maturation days from flowering to harvesting due to a decrease in speed and coloring delay.

  In addition, in this one-stage dense planting, the branches 11, 12, 13 cover each other to form a community, so that the shade that has fallen behind other leaves yellows early due to a decrease in photosynthetic capacity, etc. The shortening of the lifespan of the fruit can cause a decrease in yield and quality of the fruit 7. In addition, the deterioration of ventilation due to this canopy not only causes the inside of the canopy to become susceptible to leaf diseases such as mildew and mildew, but also because the surrounding carbon dioxide concentration is maintained at a low level. As a result, the yield and quality of the fruit 7 are reduced. Furthermore, in this one-stage dense planting, the fruit bunches 10 are hidden behind the leaves, which makes it difficult to find the fruit 7. This not only reduces the work efficiency of harvesting, but also spreads the medicine on the back of the leaves. Since it becomes very difficult, there is a drawback that the drug does not spread over the entire back surface of the leaf, and the spraying effect of the drug becomes insufficient.

Japanese Patent Publication No. 2006-000005

  Accordingly, the present invention provides a one-step dense planting method for tomatoes that can prevent fruit quality from being reduced, the number of fruits shipped, prolonged maturation days, work efficiency and chemical spraying effects from becoming insufficient. Is an issue.

  The present inventors have found that all causes of deterioration in fruit quality, reduction in the number of fruits to be shipped, prolongation of maturity days, reduction in work efficiency and inadequate drug spraying effect are due to the upper branches and leaves adjacent to the fruit bunch. It is found that the branches and leaves of the main stem are covered, and the fruit bunches and shade leaves are not exposed to sunlight, and the inside of the community is steamed. It has been completed.

  That is, in the one-stage dense planting method of tomato according to the present invention described in claim 1, after planting a plurality of tomato seedlings, the main stem is placed above the first inflorescence and the base end of the second branch leaf and 3 Truncation between the proximal end of the third branch or between the proximal end of the third branch and the proximal end of the branch of the second inflorescence, and the branches above the first inflorescence Cultivating and flowering each flower of the first inflorescence in a state in which the tip is fixed so that the tip is located above the base end, and then fruiting from each flower To do.

The invention according to claim 2 is the one-stage dense planting method of tomato according to claim 1, wherein the branches and leaves above the first inflorescence are pushed upward at the tip side, and are made of a linear body or a net-like body. Each flower of the first inflorescence is bred in a state in which the distal end is fixed so as to be positioned above the proximal end by the branching means.
Here, the linear body means a linear object such as a string, a wire or a bar, and the net-like body is formed by tying a plurality of linear bodies such as the above-mentioned strings in addition to the net. It means to include the formed net-like material.

  The invention according to claim 3 is the one-stage dense planting method of tomato according to claim 1 or 2, wherein after planting a plurality of tomato seedlings so that the first inflorescences are oriented in the same direction, the main stem is In addition, the second branch and the third leaf are located above the first inflorescence, and the second branch and the third leaf are disposed above the first inflorescence between the proximal end of the third branch and the second end of the second inflorescence. Each flower of the first inflorescence was grown and blossomed in a state in which the branches and leaves were fixed by the branching means provided on both sides of the main stem along the planting direction of the plurality of tomato seedlings. Later, fruit is produced from each flower.

  According to the one-stage dense planting method of tomato according to claims 1 to 3, in a state where the branches and leaves above the first inflorescence are fixed so that the distal end portion is located above the proximal end portion, the first inflorescence Therefore, it is possible to prevent these branches and leaves from covering the first inflorescence and the first inflorescence in which it grew, and as a result, the first inflorescence can be sufficiently exposed to sunlight, It is possible to prevent deterioration of fruit quality such as hollow fruits due to insufficient irradiation of sunlight on the bunches and the like, decrease in the number of fruits shipped due to falling fruits, etc.

In addition, by fixing the branches and leaves above the first inflorescence so that the tip portion is located above the base end, the second and third branches and leaves above the first inflorescence Moreover, the fall of the fruit quality by the fall of the photosynthetic ability of these leaves produced by covering on the 2nd branch leaf can be suppressed.
In addition, since a space is formed between the first fruit bunches and the branches and leaves, it is possible to suppress the deterioration of ventilation, and moreover, the branches and leaves under the first fruit bunches can be sufficiently exposed to sunlight. Therefore, the growth of the first inflorescence can be promoted, and the drug can be easily spread over the entire back surface of the leaves in the upper branches and leaves of the first inflorescence.

  Further, even if the branches and leaves above the first inflorescence are left as described above, it is possible to prevent the sunlight from being blocked by these branches and leaves and the deterioration of ventilation, so that the second leaves and 3 above the first inflorescence can be prevented. By pinching the main stem between the first branch and between the third branch and the second inflorescence, leaving two or three branches and leaves above the first inflorescence, these The yield and quality of fruits can be improved by photosynthesis by the leaves of branches.

  In particular, according to the second aspect of the present invention, the distal end of the branches and leaves above the first inflorescence is pushed up upward, and the distal end thereof is the proximal end by the branching means made of a linear body or a net-like body. The above-mentioned branches and leaves can be stably fixed, and further, the branching means prevents the sunlight from being blocked and the air permeability from being hindered. Since the fall of fruit quality etc. can be prevented effectively, tomato can be cultivated efficiently.

  Further, as in the invention described in claim 3, by planting a plurality of tomato seedlings so that the first inflorescences face in the same direction, the branches and leaves of all the seedlings extend in the same direction. The first branch and leaves immediately above the floret extend in the same direction, which is about 180 ° C. with respect to the direction in which the first floret extends, centering on the main stem. For this reason, even if the first branches and leaves are left as they are without being fixed by the branching means, the first branches and leaves may be covered above the first inflorescence of the tomato seedling or the adjacent tomato seedling. Therefore, the main stem is pinched above the first inflorescence between the base end of the third branch leaf and the base end of the second inflorescence branch, and the second branch leaf above the first inflorescence By fixing the third branch and leaves with branching means so that the tip part is located above the base end part, all the branches and leaves can be sufficiently exposed to sunlight, and the deterioration of ventilation is suppressed. it can. Therefore, one of the second branch and the third branch can be fixed by branching means provided on both sides of the main stem along the planting direction, and thereby, all the branches and leaves are sufficiently exposed to sunlight. In addition, deterioration of ventilation can be suppressed, and the yield and quality of the fruit can be improved by photosynthesis with more leaves, leaving the third branch and leaves.

Below, one Embodiment of the one-step dense planting method of the tomato which concerns on this invention is described using FIG. 1 and FIG.
In the one-stage dense planting method of tomatoes according to the present embodiment, first, tomato seedlings are placed on a slender, liquid-type hydroponics bed 9 installed in the north-south direction. The plants are planted at intervals of 10 cm to 20 cm so as to extend perpendicularly to the hydroponics bed 9 (in the same direction).

  Here, the first branch leaf 11 immediately above each floret has a characteristic that extends in the direction of about 180 ° C. with respect to the direction in which the branch 14 of each floret extends around the main stem 4, that is, a characteristic that extends to the east side. . In addition, the second branch 12 in the upper direction is about 90 ° C. clockwise or counterclockwise with respect to the first branch 11 around the main stem 4, and the third branch 13 is the main stem 11. 4 has a characteristic of extending in the direction of about 180 ° C. with respect to the second branch leaf 12 centering on 4. Accordingly, the second and third branches 12 and 13 extend in the direction of about 90 ° C. with respect to the direction in which the flower branch 14 extends around the main stem 4.

Next, by growing seedlings of tomatoes, the first flower located on the most main stem 4 side of the first inflorescence blooms, so between the third to seventh days after the flowering of this first flower, The main stem 4 is located above the first inflorescence above the first inflorescence with the proximal end portion of the second branch leaf 12 and the proximal end portion of the third branch leaf 13 so as to leave the two branch leaves 11 and 12 above the first inflorescence. After pinching in between, grow each inflorescence while picking the side buds.
Next, 8 to 12 days after the first inflorescence blooms, the tips of these branches 11 and 12 are pushed upward to be fixed to the branching means 5. In the meantime, each flower in the first inflorescence blooms one after another.

The branching means 5 was installed on the east side and the west side of the hydroponics bed 9 at predetermined heights in the range of 50 cm to 70 cm from the ground.
Each of the branching means 5 has a string 50 in the hydroponics bed 9 at a first position 5 cm to 10 cm apart from the main stem 4 of all tomatoes, respectively, and a second position 15 cm to 25 cm apart. Parallel to and horizontally. And the string 50 installed in the 1st position and the 2nd position is arrange | positioned at intervals of 5 cm-15 cm between both, and each branching means 5 is each in a 1st position. It is comprised by the two string 50 of the string 50 installed, and the string 50 installed in the 2nd position.

Therefore, the first branch leaf 11 immediately above the first inflorescence extends in the direction of 180 ° C. with respect to the inflorescence branch 14, that is, in the direction of the branching means 5 on the east side of the hydroponics bed 9.
For this reason, the front end side of the first branch leaf 11 is pushed upward to be fixed to the east branching means 5.

  On the other hand, the second branch leaves 12 extend above the first inflorescence in the direction of about 90 ° C. with respect to the inflorescence branch 14, that is, in the north-south direction along the hydroponics bed 9. For this reason, even if the second branch 12 is simply pushed upward, the tip of the second branch 12 may not be fixed to the branching means 5 because it is positioned away from the branching means 5.

In that case, the tip side of the second branch 12 is pushed upward from the adjacent main stem 4 or between the branches 11 and 12 toward the branching means 5 toward the east side or the west side, and then pushed upward. It is fixed to the means 5, and more preferably, it is pushed upward while being pushed toward the west side and fixed to the west side branching means 5.
Then, the first branch and leaves 11 are fixed to the east side branching means 5 and the second branch and leaves 12 are fixed to the west side branching means 5, thereby preventing the branches and leaves 11 and 12 from overlapping each other.

As a result, the first and second branches 11 and 12 are fixed by the branching means 5 so that the tip ends thereof are located above the base end. For this reason, when the branches and leaves 11 and 12 above the first inflorescence hang down, they cover the upper part of the inflorescence and block sunlight, and the lack of photosynthesis of the shade leaves due to the branches and leaves 11 and 12 covering each other is prevented. .
Furthermore, since not only the branches 11 and 12 above the first inflorescence and the first inflorescence but also the branches 18 below the sun are sufficiently exposed, the growth of the first inflorescence is promoted.

  Then, after the fruit 7 has been produced by pollination of each flower of the first flower cluster, and the first fruit cluster 10 that is an aggregate of these fruits 7 has been formed, the first fruit cluster 10 that has grown sufficiently in the sunlight. Harvest each fruit 7

According to the above-described one-stage dense planting method of tomatoes, after planting a plurality of tomato seedlings on a hydroponics bed 9 installed in the north-south direction, the two branches 11 and 12 above the first flower cluster are placed at their tips. Since the side is pushed upward and fixed by the branching means 5 so that the tip thereof is positioned above the base end, all the branches 11 and 12, the flower bunches and the fruit bunches 10 in which they grew, and the branches below them 18 can get enough sunlight.
For this reason, a decrease in the yield of fruit 7 such as hollow fruits due to insufficient solar radiation of branches 11 and 12 and insufficient solar radiation of flower bunches 10 Prolonging can be effectively prevented.

  In particular, by fixing the first branch 11 to the east branching means 5 and the second branch 12 to the west branching means 5, the second branch 12 is prevented from being covered above the first branch 11. Therefore, it is possible to prevent the yield and quality of the fruit 7 from being reduced due to the shortening of the life due to the decrease in the photosynthetic ability of the shade of the first branch 11.

Further, by arranging the branches 11 and 12 in accordance with their sizes and the like from above the string 50 at the first position to below the string 50 at the second position, or between the two strings 50. It can fix by arrange | positioning above the string 50 of a 2nd position.
For this reason, not only can a space be provided between the branches 11 and 12 and the fruit bunches 10 to positively ensure air permeability, but also the branching means 5 prevents sunlight from being blocked or obstructed. In addition, the branching means 5 can efficiently perform the cultivation management without inhibiting the spraying of the drug on the entire back surface of the leaf.

Next, another embodiment of the one-stage dense planting method of tomatoes according to the present invention will be described with reference to FIGS. 3 and 4.
In addition, about the structure same as the above-mentioned embodiment, description is simplified by using the same code | symbol.

  In the one-stage dense planting method of tomatoes according to the present embodiment, first, tomato seedlings are placed on slender liquid-type hydroponics bed 9 installed in the north-south direction. The plants are planted at intervals of 10 cm to 20 cm so as to extend perpendicularly to the hydroponics bed 9 (in the same direction).

  Here, the first branch leaf 11 immediately above each inflorescence has a characteristic that extends in the direction of about 180 ° C. with respect to the direction in which the inflorescence branch 14 extends around the main stem 4, that is, a characteristic that extends in the west side. . In addition, the second branch 12 in the upper direction is about 90 ° C. clockwise or counterclockwise with respect to the first branch 11 around the main stem 4, and the third branch 13 is the main stem 11. 4 has a characteristic of extending in the direction of about 180 ° C. with respect to the second branch leaf 12 centering on 4. Accordingly, the second and third branches 12 and 13 extend in the direction of about 90 ° C. with respect to the direction in which the flower branch 14 extends around the main stem 4.

Then, by growing seedlings of tomatoes, the first flower located on the most main stem 4 side of the first inflorescence blooms. In order to leave the upper three branches 11, 12, and 13, the main stem 4 is placed above the first inflorescence and between the base end of the third branch 13 and the base end of the second inflorescence branch. After pinching, grow each inflorescence while picking the side buds.
Next, 8 to 12 days after the first inflorescence blooms, the tips of these branches 12 and 13 are pushed upward to be fixed to the branching means 5. In the meantime, each flower in the first inflorescence blooms one after another.

The branching means 5 was installed on the east side and the west side of the hydroponics bed 9 at predetermined heights in the range of 55 cm to 75 cm from the ground.
Each of the branching means 5 has a string 50 in the hydroponics bed 9 at a first position 5 cm to 10 cm apart from the main stem 4 of all tomatoes, respectively, and a second position 15 cm to 25 cm apart. Parallel to and horizontally. And the string 50 installed in the 1st position and the 2nd position is arrange | positioned at intervals of 5 cm-15 cm between both, and each branching means 5 is each in a 1st position. It is comprised by the two string 50 of the string 50 installed, and the string 50 installed in the 2nd position.

  Therefore, the first branch 11 just above the first flower cluster extending in the direction of 180 ° C. with respect to the flower branch 14 is left as it is, and the north branch in the direction of about 90 ° C. with respect to the flower branch 14 is left. Alternatively, the second branch leaf 12 is fixed to the branching means 5 on the east side or the west side from the main stem of the tomato and the south branch in the direction of about 90 ° C. A third branch leaf 13 is fixed to the branching means 5 on the west side or the east side from the main stem of the tomato above the first inflorescence extending in the north direction.

At that time, even if the branches 12 and 13 are simply pushed upward, the tips of the branches 12 and 13 may not be fixed to the branching means 5 because they are separated from the branching means 5.
In that case, the distal end side of the second branch 12 is pushed upward from the adjacent main stem 4 or between the branches 12 and 13 toward the branching means 5 while pushing upward, and the east branching means 5 is pushed up. And the top branch side of the third branch leaf 13 is pushed upward from the adjacent main stem 4 or between its branches 12 and 13 toward the branching means 5 while pushing upward, and the western branching means 5 It fixes by pushing up toward the branching means 5 by pushing up toward the branching means 5, for example.
Then, since the second branch 12 is fixed to the east branching means 5 and the third branch 13 is fixed to the west branching means 5, the second branch 12 and the third branch 13 are different. The branch leaves 12 and 13 are prevented from overlapping each other.

As a result, the second and third branches 12 and 13 are fixed by the branching means 5 so that the distal ends thereof are located higher than the base ends, and the first branches 14 are attached to the first inflorescence. Since the stem 14 extends in the direction of about 180 ° C. around the main stem 4 with respect to the direction in which the stem 14 extends, the branches 11, 12, 13 above the first inflorescence hang down, covering the upper portion of the inflorescence and sunlight. Insufficient photosynthesis of the shade leaves due to blocking or covering the branches 11 and 12 is prevented.
Furthermore, since not only the branches 11, 12, 13 above the first inflorescence and the first inflorescence but also the branches 18 below the sun are sufficiently exposed, the growth of the first inflorescence is promoted and the branches 11 In addition to 12 and 12, the photosynthesis of the branches and leaves 13 can improve the yield and quality of the fruit.

  Then, after the fruit 7 has been produced by pollination of each flower of the first flower cluster, and the first fruit cluster 10 that is an aggregate of these fruits 7 has been formed, the first fruit cluster 10 that has grown sufficiently in the sunlight. Harvest each fruit 7

  According to the above-described one-step dense planting method of tomatoes, after planting a plurality of tomato seedlings on a hydroponics bed 9 installed in the north-south direction so that the branches 14 of the first inflorescence extend from the main stem 4 toward the east. The main stem 4 is pinched above the first inflorescence between the proximal end of the third branch 13 and the proximal end of the second inflorescence branch, and the second branch 12 above the first inflorescence. And the third branch 13 are fixed so that the distal end of the third branch 13 is pushed upward by the branching means 5 so that the distal end is positioned higher than the base end, so that all the branches 11, 12, 13 are left. However, the branches 11, 12 and 13, the flower bunches and the fruit bunches 10 on which they grow and the branches and leaves 18 thereunder can be sufficiently exposed to sunlight, and the yield and quality of fruits can be improved by photosynthesis with more leaves. it can.

  Further, the branching means 5 not only provides a space between the branches 11, 12, 13 and the fruit bunches 10 to positively secure the air permeability, but also prevents sunlight from being blocked and the air permeability from being hindered. In addition, the branching means 5 and the other branches 11, 12, and 13 do not hinder the spraying of the medicine on the entire back surface of the leaves, and the cultivation management can be performed efficiently.

  In addition, this invention is not limited to the above-mentioned embodiment at all, For example, the branching means 5 may be comprised not with the string 50 but with the net | network.

  Next, Example 1 in which tomato seedlings were grown according to one embodiment described above, Comparative Example 1 as a comparison target, Example 2 in which tomato seedlings were grown according to other embodiments, and the comparison Comparative example 2 as an object will be described below.

[Example 1]
In a submerged hydroponic bed 9 installed in the north-south direction, tomato seedlings that had grown to about the fifth leaf stage on March 24 were planted at 12.5 cm intervals and grown.
Then, the first flower of the first inflorescence blossomed on April 14th, 21 days after planting.

  Next, on April 19, five days after the flowering date, the main stem 4 is placed above the first inflorescence so that the two branches 11 and 12 above the first inflorescence remain. While pinching between the proximal end portion and the proximal end portion of the third branch leaf 13, the branching means 5 was installed at a height of about 60 cm from the ground portion. At that time, the first position is set at a position 10 cm away from all the main stems 4 and the second position is set at a position 20 cm away from all the main stems 4. A string 50 was installed.

After that, on April 24, 10 days after the flowering of the first inflorescence, these two branches and leaves 11 and 12 are forcibly pushed upward by hand, respectively, and the branching means 5 uses the branching means 5 to The first inflorescence was grown in a state where the portion was fixed so as to be positioned above the base end. In the meantime, each flower of the first inflorescence blossomed one after another, and fruit 7 was produced by pollination or the like.
The fruit 7 was then grown and then harvested.

[Comparative Example 1]
First, in the same manner as in Example 1, seedlings of tomatoes grown to about the fifth leaf stage were planted and grown in the submerged hydroponics bed 9. Then, on the 21st day after planting, the first flower in the first inflorescence blossomed.
Next, 5 days after the flowering date of the first floret, the main stem 4 is pinched between the proximal end of the second branch 12 and the proximal end of the third branch 13 above the first floret. These branches 11 and 12 were grown as they were without being pushed upward, and the fruits 7 of the fruit bunches 10 were harvested.

  Then, the tomato of Comparative Example 1 has a growing period of about 7 days longer than that of Example 1, and the occurrence of hollow fruits is also increased by about 10% compared to Example 1. have done.

[Example 2]
In a submerged hydroponic bed 9 installed in the north-south direction, seedlings of tomatoes grown to about the 4th leaf stage on April 18 were planted at 10 cm intervals and grown. At that time, the plants were planted so that the branches 14 of the first inflorescence of each seedling extended from the main stem 4 toward the east.
Then, the first flower of the first inflorescence bloomed on May 10th on the 22nd day after planting.

  Next, on May 10 of the flowering date, the main stem 4 is placed above the first inflorescence 13 so as to leave the three branches 11, 12, 13 above the first inflorescence. While pinching between the end part and the base end part of the branch of the second inflorescence, the branching means 5 was installed at a height of about 60 cm from the ground part. At that time, the first position is set at a position 10 cm away from all the main stems 4 and the second position is set at a position 20 cm away from all the main stems 4. A string 50 was installed.

Thereafter, on May 12, two days after the flowering of the first inflorescence, the distal ends of the two branches 12 and 13 are forcibly pushed upward by hand, and the branching means 5 is used to base the distal ends thereof. The first inflorescence was grown in a state of being fixed so as to be positioned above the end. At that time, the branches 12 and 13 were fixed by different branching means 5 on the east side or the west side.
Then, each flower of the 1st inflorescence blossomed one after another, and fruit 7 was grown by pollination etc.
The fruit 7 was then grown and then harvested.

[Comparative Example 2]
First, in the same manner as in Example 2, seedlings of tomatoes grown to about the 4-leaf stage were planted and grown at 10 cm intervals in the submerged hydroponics bed 9. However, the plants 14 were planted so that the branches 14 extended in different directions depending on the seedlings without considering the extending direction of the branches 14 of the first inflorescence of each seedling.
Then, on the 22nd day after planting, the first flower of the first inflorescence blossomed.
Next, on the day of flowering of the first inflorescence, the main stem 4 is placed above the first inflorescence with the base end of the third branch leaf 13 so as to leave the three branches 11, 12, 13 above the first inflorescence. While performing pinching between the base ends of the branches of the second inflorescence, the same branching means 5 as in Example 2 was installed.

Thereafter, on May 12, two days after the flowering of the first inflorescence, the first branch leaf 11 immediately above the first inflorescence shields the first inflorescence of the adjacent seedling, so that the branch leaf 11 including the first branch leaf 11 is included. , 12 and 13 were forcibly pushed upward, and the first inflorescence was grown with the branching means 5 fixed so that their distal ends were positioned above the proximal end.
Then, each flower of the 1st inflorescence blossomed one after another, and fruit 7 was made to grow by pollination etc., and after harvesting these fruit 7, it harvested.

  In the tomato of Comparative Example 2, since two branches and leaves of the branches 11, 12, 13 are fixed by the east or west branching means 5, the branches are shielded from each other, and the leaves are yellowed. The yield decreased by about 10% compared to Example 2.
