Abstract

PROBLEM TO BE SOLVED: To easily take out a seedling from the inside of a pot along with a seedling raising base material at the time of taking out the grown seedling from the inside of the pot in the case of filling bed soil inside the pot for raising the seedling, sowing a seed and raising the seedling. SOLUTION: The seedlings of a rice plant and vegetables are raised in a pot seedling container 1 whose whole body is in a quadrilateral shape for which the pots 2 for raising the seedlings made of resin or paper are molded while disposing desired pitches on left and right sides and on front and back sides and the pots 2 for raising the seedlings are mutually continued. In this case, a base material lump 3 in a prescribed shape composed of the seedling raising base material such as water-soluble non-woven fabric 4 or water containing urethane foam or the like is fed inside the respective pots, a seedling raising seed 7 such as a rice seed and a vegetable seed is sown thereafter, watering or nutritious liquid immersion is performed and the seedling is raised.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for raising seedlings such as rice and vegetables.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Application Laid-Open No. 53-156808, a seeding groove is formed in foaming urethane foam as a substitute for a bed soil for raising seedlings, and laid in a seedling box. Although seeding and raising seedlings are known, a large number of seedling raising pot groups are used for raising seedlings in pot raising seedling containers molded of resin or paper.In the seedling raising pots, blocks of foaming urethane other than floor soil are contained. No seedlings were grown by feeding the population of parenting seedlings.

[0003]

Conventionally, when sowing and raising seedlings by filling the soil in a pot for raising seedlings, when removing the grown seedlings from the pot, the floor soil collapses and it is difficult to reliably remove the seedlings. Was. In particular, it is very difficult to grow seedlings or vegetable seedlings that are poorly grown and do not show sufficient root growth because fine roots do not grow.

[0004]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, the seedling raising pot 2 made of resin or paper is formed by arranging desired pitches on the left and right sides and the front and rear sides, and the whole of the seedling raising pots 2 being continuous with each other has a square shape in plan view. In order to raise rice and vegetable seedlings in the container 1, a base material mass 3 having a predetermined shape made of a seedling parent material such as a water-soluble nonwoven fabric 4 or a water-containing urethane foam is put into each of the pots. A seedling raising method characterized by sowing seedlings 7 of seed rice and vegetable seeds and irrigating or immersing in a nutrient solution to raise seedlings.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One example of the present invention will be described in detail with reference to the drawings. 1 is an embodiment of a pot seedling container, which is made of synthetic resin,
The seedling-growing pots 2 each having a cup shape at a predetermined pitch are arranged on the left and right sides and the front and rear sides, and adjacent pot upper sides are connected. The seedling raising pot 2 has a hole (a) on the bottom surface from which the root extends. The entire front and rear sides are formed in a long rectangular shape in plan view. The container 1 may be made of paper, and the shape of the pot 2 may be rectangular.

Reference numeral 3 denotes a parent material mass serving as a seedling raising parent material, which is formed by molding a nonwoven fabric 4 into a rectangular mass, and the parent material mass 3 is large enough to be put into the pot 2. As another example of the base material lump 3, a block in which the urethane foam 4a is formed in a square shape may be used, as long as the root can easily penetrate. Numeral 5 is a seedling raising box having a large number of drainage holes (b) formed on the bottom surface, and has a size that allows the pot seedling container 1 to fit therein.

Numeral 6 is a nutrient solution bed for hydroponic cultivation, which stores a cultivation solution in which fertilizers and the like are dissolved. The seedling cultivation means will be described. After the pot seedling container 1 is fitted into the seedling raising box 5 and the parent material lump 3 is put into each pot 2, 3 to 5 seeds 7 are sown, and watering or seedling is performed. Raise seedlings by immersing the whole box in the culture solution. Alternatively, after putting the parent material lump 3 into the square pot 2 without putting the pot seedling container 1 into the nursery box 5,
3 to 5 seed rice 7 are sown, and the bottom is submerged in the cultivation solution in the nutrient solution bed 6 for cultivation.

When growing vegetable seedlings, it is preferable to sow one vegetable seed 8 instead of the seed rice 7. When the seedlings are raised in this manner, the roots of the germinated seedlings penetrate into the parent material lump 3, and the roots extend around the lump 3 with the parent material lump 3 as a nucleus, and the seedlings are raised. . Therefore, when the grown seedlings are taken out of the pot 2, if the roots penetrate into the base material lump 3, the roots collect around the lump 3,
It is extremely easy to take out, and even if the seedling is mechanically extruded from the hole (a) at the bottom of the pot 2, it can be easily extruded. In any case, the mechanical planting of the seedling is simple and reliable. When the pot seedling container 1 is made of a thin flexible resin, the bottom plate of the pot 2 is easily opened by pressing with a pin or the like, and a crack is radially provided from a small hole in the center to be always closed. It may be a mold hole.

The structure of the base material mass 3 is formed by wrapping the seedling cultivation soil 9 appropriately in a tubular shape with the nonwoven fabric 4, so that the seedling cultivation soil 9 is raised during the seedling raising.
The seeds are sown therein, and the seedling raising soil 10 is filled in the gap between the pot 2 and the base material lump 3, and the seedlings are raised by covering the soil 11. In this way, the roots of the seedlings to be raised initially extend into the seedling cultivation soil 9, then pass through the nonwoven fabric 4 and grow in the outer seedling cultivation soil 10, and the root between the pot 2 and the nonwoven fabric 4 becomes honey. Potted seedlings that grow and are easily taken out of the pot 2 can be raised.

A seeding hole (c) is provided in the base material mass 3 in which the seedling cultivation soil 9 is appropriately wrapped in a cylindrical shape with the nonwoven fabric 4 and the seeding hole (c) is placed in the seedling raising pot so that the seeding hole (c) is on the upper side. After that, seedlings may be sown, and in this state, the seedlings may be irrigated or immersed in a nutrient solution for an appropriate number of days, and then seedlings may be supplied to the gap between the seedling pot and the base material mass 3 to grow the seedlings.

[0011]

According to the present invention, the roots of the seedlings to be raised grow nectar inside and outside with the base material mass 3 as a nucleus, and the seedlings can be taken out very easily when taken out from the pot. . Also, when the pot container is made of paper, a pot-shaped seedling with a sufficient shape can be obtained even if the paper as the container is humified.
