Abstract

PURPOSE:To obtain a nursery greenhouse, provided with a self-control type heater, sensing the surrounding temperature and automatically increasing or decreasing the quantity of electricity, cuttable and connectible to a required length between a nursery pot and the ground surface, and providing good growth conditions even by mechanical planting and high quality and yield. CONSTITUTION:In a nursery greenhouse 4 for raising healthy seedlings, a self- control type heater 2, capable of automatically increasing or decreasing the quantity of electricity while sensing the surrounding temperature, cuttable and connectible to a required length is arranged between a nursery pot 1 and the ground surface 3. Furthermore, an object 5 such as an aluminum foil having thermal conductivity, as necessary, can be arranged between the nursery pot 1 and the self-control type heater 2 to always maintain the constant atmospheric temperature and soil temperature in the nursery greenhouse 4, according to the kind of crops without any regard to the four seasons. Thereby, healthy seedlings having thick and strong grown roots thereof are obtained.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a seedling growing house in which a self-regulating heater is arranged under a seedling growing pot in order to grow the roots of the seedlings to be thick and large and strong.

<Conventional technology> In order to grow healthy seedlings, heating wires such as nichrome wires are placed under seedling pots in greenhouses, etc., and pipes are placed to run hot water through them, etc., in seedling houses, etc. was.

<Problems to be solved by the invention> When heating wires such as nichrome wires are used under seedling pots, the heating wires are expendable and have many problems in terms of safety, economy, durability, and simplicity. This technique is hardly practiced at present, as it has not been possible to train it. Also, if you want to run hot water through pipes, you will need to install a boiler, and if you install a boiler, the greenhouse or other seedling house will become permanent, and it will be easy to install even if you no longer need the greenhouse. This technique is currently only used in some areas because it cannot be removed and requires specialized skills for installation and removal, which is extremely inconvenient and uneconomical due to the high installation costs.

Furthermore, seedlings sown at the edge of a greenhouse such as a plastic greenhouse in particularly cold regions with irregular temperatures should be planted at one-fifth of the size of the seedling pot.
The seedlings were not aligned properly, and the quality conditions of the seedlings were poor, and past growth surveys after transplanting showed that this had an effect on the harvesting period, causing problems in yield and quality.

Therefore, the present invention recognizes that the quality of seedling quality is directly related to early growth even now that mechanical transplantation has become widespread, and also affects yield and quality. It was invented with the aim of overcoming the drawbacks of the conventional techniques and growing the roots of seedlings to grow thick, large and strong, and to grow healthy seedlings, focusing on the fact that mechanical planting does not change much. .

<Means for Solving the Problems> In order to achieve the above object, the seedling raising house of the present invention is capable of automatically increasing or decreasing the amount of electricity between the seedling raising pot and the ground while sensing the ambient temperature. It is equipped with a self-regulating heater that can be cut or connected to the required length.

Furthermore, an object having thermally conductive hair may be placed between the seedbed and the self-regulating heater.

<Function> The heater used in the present invention must be a self-control type heater that can automatically increase or decrease the amount of electricity while sensing the surrounding temperature, and can be cut or connected to the required length.
This self-regulating heater is placed between the seedling pot and the ground, and when this self-regulating heater is used,
The heat generated by the heater is averaged out even if the temperature and hot water inside the seedling nursery house are high or low, and the amount of heat generated changes depending on the temperature and hot water inside the nursery house, so the temperature suitable for the growth of seedlings is always kept constant. This allows the seedlings at the edges of the nursery house to maintain the appropriate humidity for growth in the same way as the seedlings in the center, and at the same time improves thermal efficiency, reducing electricity costs. be.

<Example> Examples will be described with reference to the drawings.

FIG. 1 shows a seedling raising house according to the present invention, in which a self-regulating shed 2 is placed between a seedling raising pot 1 and the ground 3. Fig. 2 is a partially enlarged view of Fig. 1, showing the present invention more clearly, and Fig. 3 is a diagram showing the arrangement of the seedling growing pot l, with the seedling growing pot at the end They are indicated by a, a', b, b'. Seedling raising pots vary depending on the crops to be grown, such as rice, onions, beets, etc., and the self-regulating heater 2 of the present invention can be used for any of them.

This self-control type heater 2 is a type that can automatically increase or decrease the amount of electricity while sensing the ambient temperature, and can be cut or connected to the required length, and is a heater developed by Raychem.

FIG. 4 is a diagram showing that a thermally conductive object 5 is placed between the seedling growing pot 1 and the self-controlling heater 2.
This object 5 is, for example, aluminum foil.

<Effects of the Invention> Since the present invention is configured as described above, it produces effects as described below.

We decided to install a self-control heater that can automatically increase or decrease the amount of electricity while sensing the ambient temperature, and can be cut or connected to the required length.

Regardless of the four seasons, it is possible to maintain a constant temperature and hot water inside the nursery house depending on the type of each crop.
As a result, the roots of the seedlings can always be kept at a temperature suitable for their growth, and the temperature of the seedlings in the center of the nursery house and the seedlings at the edges are kept the same, which prevents the occurrence of irregular seedlings. This is something that can be prevented. As a result, according to the present invention, the roots of the seedlings can be grown to be thick, large, and strong, and healthy seedlings can be grown.

Particularly in the case of end seedlings in seedling houses in cold regions, seedlings are uneven in one-fifth of the seedling pots, and the quality conditions of m are poor, and past growth surveys have shown that this affects the harvest period, causing problems in yield and quality. The present invention solves this problem. This made it possible to secure a stable yield of 600i (/10a).

In addition, since it can be cut or connected to the required length, it is convenient because it can be adjusted appropriately according to the size of the seedling growing house, the size of the seedling growing pot, etc.

Furthermore, it is economical as it does not require a permanent facility, and electricity costs can also be reduced.

Further, if a thermally conductive object such as aluminum foil is placed between the seedbed and the self-regulating heater, the thermal conductivity to the surrounding area will be improved and the effect can be further improved.
