Description

  The present invention belongs to a technical field relating to a method for growing seedlings to be transplanted into a field and a seedling box used for seedling growth.

  When dropping seedlings from the seedling supply table of the vegetable transplanter, there is a cultivation method that forms root pots by spreading the roots in the cultivation soil in order to put the seedlings into the planting device in a posture suitable for planting, When raising the roots of potatoes, such as kansho, the roots will become enlarged and become wrinkles if time passes too much, but they will be deformed due to pressure in the seedling pot, but the number of each cocoon will increase May become smaller.

  In order to prevent excessive growth of moss seedlings in nursery pots, seedlings such as feed rice are first grown in nursery pots to form root pots, and moss seedlings in the soil that began to become root pots There is a method for raising seedlings (see Patent Document 1).

Japanese Patent Laying-Open No. 2015-104353

  By shortening the seedling raising period of moss seedlings, the roots can be enlarged and transplanted to the field before being pressed into the seedling pot, so the harvested cocoons are twisted or bifurcated It is hard to be done, it is easy to become the appearance, and the fall of the commercial value is prevented.

  In addition, the pressure on the root can prevent the buds from becoming excessively large and become cocoons, preventing the cocoons from contacting each other and preventing each other from growing, The size can be increased.

  However, the seedling pot for raising seedlings by introducing the culture soil has an opening on the upper side, but a bottom is formed on the lower side, and there are slits for draining water, but it is almost sealed. .

  In this state, when the root portion grows downward from the soil, the root portion comes into contact with the inside of the wall surface or the bottom portion, and a so-called root winding is generated that continues to grow by bending in another direction. When the bent portion is enlarged and becomes a cocoon, the harvested cocoon is also bent and has a problem that the commercial value is lowered.

  Deformation is not a major problem for processing, but for raw foods whose appearance leads to commercial value, it becomes a major problem because it reduces the commercial value or has no commercial value.

  In addition, since roots basically continue to grow if they are present in the soil, if they cannot be planted at an appropriate time for transplanting seedlings, they start to grow in the soil and are planted in the field under pressure. As a result, there arises a problem that the cocoon is deformed and the size of the harvested cocoon is reduced.

  An object of the present invention is to provide a seedling raising method for preventing the occurrence of root winding during raising seedlings and preventing the enlargement of roots during cultivation, and a nursery box used for seedling growth.

  In order to solve the above problems, the following technical measures were taken.

  One embodiment of the present invention will be described below. The following embodiment is merely an embodiment and does not restrict the scope of the claims.

  A seedling tray 1 for growing seedlings N such as kansho is a united arrangement of a plurality of seedling pots 2 arranged vertically and horizontally at equal intervals, and contacts the outer peripheral edge when holding the seedling tray 1 in a floating state. The edge 3 to be formed is formed.

  As shown in FIGS. 1 to 3, the seedling pot 2 has an upper opening 2a having a square shape, for example, a square shape at the upper end, and has a shorter vertical and horizontal side at the lower end than the upper opening 2a, in other words, a smaller area. It is a hollow structure that forms the lower opening 2b, and the posture is toward the center of the seedling pot 2, that is, toward the center of the intersection of the diagonals of the upper opening 2a and the lower opening 2b as it goes downward between the upper and lower sides. The pot wall portion 2c is formed by forming a total of four sides in the vertical and horizontal directions. That is, the seedling pot 2 has a quadrangular pyramid shape in which the lower side has a smaller cross-sectional area than the upper side. At this time, when the angle formed by the upper virtual edge 2x of the upper opening 2a of the seedling pot 2 and the pot wall 2c is 75 degrees or more, the shape of the root pot formed by the root Na of the seedling N and the culture soil 4 described later Can be improved according to the shape of the planting device of the vegetable transplanter.

  The seedling tray 1 is mainly prepared by molding a synthetic resin in a mold, but a plurality of seedling pots 2 are formed from one material even if a plurality of seedling pots 2 are created and connected. It may be configured as follows.

  As described above, the plurality of seedling pots 2 have a structure penetrating in the vertical direction. When raising the persimmon seedling N, as shown in FIG.3 and FIG.8, it extends over the predetermined length (example: 5-10 mm) from the lower side opening part 2b among the upper and lower sides of this seedling pot 2 at least. A portion of the seedling N, which is prepared by cutting the stem portion of the potato into every predetermined number of nodes, is inserted into the soil 4 and grown while irrigating.

  Root Na is generated from the portion inserted into the soil 4, and the surrounding soil 4 is pushed apart, or extends through the gaps between the particles of the soil 4, and the root Na is intertwined in the soil 4 in a complex manner. The root pot shown in FIG. 4 (a) is formed. Thereby, since weight concentrates on the lower side of the seedling N, when moving the seedling N from the seedling supply device of the vegetable transplanter to the planting device, a certain fall speed can be secured and the root Na is positioned on the lower side. Since the posture to be maintained can be maintained, the planting accuracy is improved and the growth after planting is improved.

  On the other hand, in the portion of the seedling N that is not in contact with the culture soil 4, the leaf portion Nb is generated from the joint of the node and the top as it grows.

  Since the lower opening 2b is formed in the lower part of the seedling pot 2, the root Na of the grown seedling N extends into the space at the bottom of the soil 4 as shown in FIG. . Since this root Na hardly bends in contact with the seedling pot 2, it extends almost straight downward. Therefore, the root Na is prevented from being rooted, and the shape of the potato that is grown and harvested can be stabilized.

  When the root Na is enlarging and growing in a state where the root is wound, there is a problem that the product value is lowered due to poor appearance and difficulty in removing the skin, because the cane tends to be elongated and twisted. However, this problem is unlikely to occur in the seedlings of the present application because the root Na is difficult to wind. However, since the possibility that the potato is deformed also affects the environment of the place where it is cultivated, it is necessary to pay attention to the soil quality of the field and the method of planting the seedlings N.

  In addition, the portion of the root Na that extends downward from the cultivating soil 4 and is exposed to the air continues to touch the air. Then, as shown in FIG.4 (b), root part Na becomes a woody part from this part, and while extending | stretching stops, it will be in the state which cannot form a mustard. However, since the wooded part has not lost the property of growing new root Na, as shown in FIG. 4 (c), new roots can be extended in the soil after transplanting, and can be enlarged.

  As a result, it is possible to grow new root Nc that grows freely in the soil from the wooded root Na instead of the root Na that has grown and concentrated in the seedling pot 2 and becomes woody, The shape of the kansho is made into a well-organized shape with a high commercial value, and the size of the kanshi can be increased by making it difficult to gather together in the soil, so that the commercial value can be further improved. .

  In addition, when the culture soil 4 for raising seedlings is put into the seedling tray 1, the culture soil 4 does not accumulate only with fine sandy particles. Also, when water for irrigation flows out from the lower opening 2b, sandy material flows out, the cultivating soil 4 is insufficient and the seedling N grows poorly, and the weight on the lower side of the seedling N is increased. There is a risk that it will not be a seedling suitable for planting work using a vegetable transplanter.

  In order to prevent this problem, as shown in FIG. 5, the soil 4 is made of long fibers derived from moss and palm as raw materials such as peat moss 6a and coconut shell 6b, etc. The fiber material 6 to be formed is mixed.

  Thereby, when a certain amount of the soil 4 is put into the seedling pot 2, the space 4 can be formed on the lower opening 2b side while the soil 4 is accumulated in the seedling pot 2, so that it is inserted. The growth of the seedling N can be stabilized, and the root Na of the seedling N can be prevented from being wound, and can be brought into contact with air to promote wooding.

  In addition, when the length of the fiber material 6 is shorter than the length of one side of the upper opening 2a and longer than the length of one side of the lower opening 2b, the cultivated soil 4 is easily accumulated in the seedling pot 2. Further, in order to form a root pot formed by the root Na of the seedling N and the cultivating soil 4 vertically, the root pot of the seedling pot 2 is more than twice the length of one side of the upper opening 2a. Is sufficiently heavy so that the center of gravity is positioned on the lower side of the seedling N, and the posture of the seedling N that falls from the seedling supply table of the vegetable transplanting machine and moves to the planting device is difficult to change during the fall.

  However, if the fiber material 6 is excessively mixed, the soil quality of the culture soil 4 is insufficient, and the nutrients necessary for the growth of the seedling N cannot be secured. Therefore, the mixing amount of the fiber material 6 may be less than 30% in weight ratio. desirable.

  In the above, by forming the lower opening 2b in the lower part of the seedling pot 2, it is possible to prevent the occurrence of deformed picking due to the root winding of the root Na, but in order to obtain this effect, at least the seedling Until N grows to a stage where it can be transplanted using a vegetable transplanter, it is necessary to keep the seedling tray 1, that is, the bottom of each seedling pot 2, not in contact with the ground.

  In order to realize this, as shown in FIGS. 6 to 9, each seedling pot 2 during the seedling N seedling is inserted at least between the front and rear or the left and right, and the bottom of each seedling pot 2, that is, the lower side A seedling support frame 7 having a plurality of support bars 7a to be supported in a state where the lower part of the opening 2b is not grounded is prepared.

  The seedling support frame 7 is configured by arranging a support bar 7a in an outer frame 7b in a vertical direction, a horizontal direction, or a vertical and horizontal position at a position where it can enter between the seedling pots 2. The seedling support frame 7 is preferably fixed at a certain height such as a wall surface or a column, and is placed at a height at which the bottom of each seedling pot 2 of the seedling tray 1 is not grounded.

  Alternatively, when four seedling support frames 7 are provided between the four corners of the seedling support frame 7 and between the four corners, and the seedling support frame 7 is loaded with the support legs 7c grounded on the floor surface, each seedling pot of the seedling tray 1 is loaded. It is good also as a structure by which the bottom part side of 2 is mounted in the height which is not grounded.

  By the above, it is prevented that the root Na of the seedling N is wound up, and the root Na is enlarged and is prevented from being deformed, and the root Na is made into a woody structure before the seedling N is planted. Therefore, the root Na starts to enlarge and prevents the seedling N from being suitable for planting.

  In addition, the seedling inserted into the cultivating soil 4 causes at least a stem P of the stem to enter the cultivating soil 4 and prevents the leaf portion Nb from being simultaneously generated from the portion where the root portion Na is generated. When the occurrence position of the root Na and the leaf Nb is from the same node, it becomes difficult to plant the seedling N deeply, and there is a risk that the mutual growth may be balanced with nutrients, resulting in poor growth. The occurrence of this problem is prevented.

  It is desirable to transplant the seedlings in the field before the buds are generated between the root of the leaf Nb and the stem. When these axillary buds occur, adventitious roots begin to develop at the same time from the stem, but these adventitious roots can become fertile when enlarged. Therefore, if extra candy is generated and the growth space of each candy is narrowed, the number of citrus fruits with commercial value may be reduced.

  The seedling N suitable for planting with a conventional kanko transplanter generates seedlings from seed potatoes and harvests them from there. As shown in FIG. 10A, the seedling thus obtained has a narrow stem, the leaf portion Nb tends to gather at a position away from the stem, and the side where the leaf portion Nb does not grow is placed on the planting sandwich. This makes it easier to grab and get into the soil and improve work efficiency. The cane obtained from this seedling tends to be small in size, and is mainly used for processing confectionery, sake brewing, etc. rather than raw food.

  On the other hand, the persimmon seedlings shown in the present application are not directly harvested from seed potatoes, but are obtained by dividing seedlings grown for seedling in a virus-free environment into several sections. As shown in FIG. 10 (b), this seedling is a stiff seedling in which a leaf portion Nb is generated at each node of a narrow and thick stem, and the leaf portion Nb is arranged in the long side direction of the stem. This seedling can be planted immediately after being cut, and root Na is generated in the transplanted soil.

  However, the above-mentioned seedling has a short interval between the leaf parts Nb, the interval between the part where the root Na is generated and the leaf part Nb is also short, and it is difficult to grasp the seedling N in the transplanting sandwich of the conventional anchovy transplanter, Moreover, it is difficult to draw a locus that allows only the root Na to enter the soil without causing the leaf Nb to enter the soil even if it is grasped.

  When transplanting seedlings such as lettuce and radish with a planting device instead of the conventional Kanko transplanter, the side opposite to the side where the root Na is generated becomes heavier with the weight of the leaf Nb. Therefore, the posture in which the seedling N enters the planting hopper becomes unstable, and the root Na may not be planted in the soil.

  In order to solve this problem, it is necessary to give a weight corresponding to the soil 4 or the like to the side where the root Na is generated. As an example, it is conceivable to provide a weight body 8 shown in FIG. 11 that is attached to the seedling N with the node and the base of the petiole closest to the root Na side interposed therebetween. Because of the weight 8, seedlings falling from the seedling supply device are put into the planting device from the root Na side, so that the root Na side surely enters the soil and the enlarged root Na is selected. Can do.

  At this time, if the weight body 8 is left in the soil, it may cause the harvesting to be hindered or damaged when it is harvested. Further, if the weight body 8 remains near the root portion Na, the root portion Na may come into contact with the weight body 8 to cause root winding, which may grow into a deformed shape.

  In order to prevent this, the weight body 8 is decomposed by, for example, bacteria in the soil, chemical change with water or air, decomposes over time, becomes nutrient in the soil, and can be absorbed by the root Na. It is good to comprise with the solid substance formed with organic substance.

  As an example of a material constituting the weight body 8, it is conceivable to use a biodegradable plastic such as starch or casein, or a biodegradable material such as peat moss or coconut shell obtained by drying mud carbonized moss. By being composed of these materials, the weight body 8 is naturally decomposed in the soil, and is used as a nutrient for the growth of the potato seedlings N, so that the potatoes can be prevented from being damaged during the harvesting operation and the initial growth can be achieved. Can function as a fertilizer for time.

  However, if the weight 8 is formed by mixing a plurality of materials, the weight of the weight 8 may be biased and the posture of the seedling N may become unstable, so the material constituting the weight 8 Is preferably a single unit.

  The biodegradable materials mentioned above are mixed into the soil over time to become nutrients and have a small environmental impact.However, depending on the field environment, decomposition may be slow, and if they are not fully decomposed during harvesting, they may damage the sweet potato. is there.

  Therefore, the weight body 8 is preferably composed of a chemical fertilizer capsule so that the weight body 8 is surely decomposed and absorbed and disappears in a short time after planting.

  As a result, due to the influence of moisture in the soil, the weight body 8 is quickly eluted as a nutrient and absorbed by the root Na generated from the seedlings. Is prevented.

  However, some growers do not want to use chemical fertilizers. At this time, the weight 8 may be formed of an organic material formed into a pellet.

  In any case, as shown in FIG. 11, the weight 8 is formed in a spherical shape, a cubic shape, or a cylindrical shape, and a through-hole for inserting the seedling N is formed. The seedling N is inserted through the through hole from the root Na side, and the node closest to the root Na and the petiole of the leaf Nb are sandwiched and attached so that the portion where the root Na is generated is not covered with the weight body 8.

  As a result, since the weight concentrates on the side where the root Na of the seedling N is generated, when the seedling N is dropped, the seedling falls with the weight 8 side as the lower side. Therefore, planting in the field with a vegetable transplanter It can be set as the seedling N suitable for work.

  Moreover, since the weight body 8 does not inhibit generation | occurrence | production or growth of root Na, the growth failure and malformation of a potato are prevented.

  Next, a method for raising a seedling capable of sufficiently securing the strength of the root pot before root curling will be described when cultivating the potato seedling N in the seedling tray 1 will be described.

  As shown in FIG. 12, the culture soil 4 is covered with the seedling tray 1, and rice bran 9 such as feed rice is seeded on the culture soil so that four or more grains enter the seedling pot 2 on average. RN is cultivated first. The sowing work of the cocoon 9 is performed at least three weeks before the seedling N of mandarin is inserted into the seedling tray and the seedling is started.

  In addition, although the said raising seedling pot 2 may use what opened said bottom part, there is no problem in the conventional thing which is not opened.

  Thus, as shown in FIG. 13, the root portion RNa of the rice seedling RN that is thinner than the root portion Na of the potato and does not grow so much even when grown is stretched first in the cultivation soil 4 and used for the formation of the root pot. It is possible to shorten the period from inserting the potato to the root pot with the strength suitable for transplanting with the vegetable transplanting machine, and transplanting work before the root winding occurs near the bottom of the seedling pot 2 It can be performed.

  Moreover, since it can be cultivated even with a small amount of feed rice together with kansen, it is possible to harvest two types of crops in one field.

  However, if all the sowed rice seedlings RN are grown, the nutrients in the soil 4 and the field will be exchanged with each other, which hinders the growth of the cane and reduces the size of the harvested cane.

  In order to prevent this, the herbicide corresponding to the grass family plant is sprayed on the seedling tray 1 at the stage immediately before the seedlings N of the potatoes are inserted into the seedling pot 2. Since Kansai is a convolvulaceae plant, it is not affected by the herbicide, but the rice seedling RN will die. However, if all the rice seedlings RN are withered, the rice can no longer be harvested. Therefore, the herbicide is set to a concentration or amount at which 50 to 80% of the rice seedlings RN die, or sprayed over a range. And

  Thereby, even if the nutrients of the cultivation soil 4 and the field are combined, the sugar cane can be enlarged to a sufficient size, so that the quality of the harvested cane is high and the commercial value is improved. In addition, by making the paddy rice cultivated at the same time one for feed rice, even if the taste is low, the commercial value is hardly affected.

  When the rice seedling RN 9 is densely sown, the roots of the rice seedling RN 9 tend to be thin, and the strength of the root pot is insufficient.

  In order to prevent this problem, by adding 30-100 g of superphosphate lime having a phosphorus P concentration of around 17% per liter of the soil 4, even if the thin root Na is dense, the phosphoric acid that is a nutrient is added. Since sufficient supply can be achieved, the root Na in the cultivating soil 4 can be improved, and the strength of the root pot can be made suitable for transplantation with a vegetable transplanter.
