Abstract

PURPOSE: To provide a watering method similar to a natural environment for the healthy growth of a potted plant, and to provide a device therefor. CONSTITUTION: Two or more through holes are bored in the lid of a watering container. Both the ends of a string-like water-absorbing member are introduced into the through holes of the lid, and immersed in the water for watering in the watering container. A sheet is loaded on the upper surface of the string-like water-absorbing member, and a potted plant is further loaded on the sheet and subsequently cultured. Each of the through holes bored in the lid is holes somewhat larger than the width of the water-absorbing member, but the water-adsorbing member may directly be immersed in the watering container without boring the through holes. This method is advantageous for the production of crops in the farmhouse. A cheese cloth, cloth, paper, peat moth, etc., may be utilized as the sheet loaded on the water-adsorbing member. Since the method can provide an environment similar to the natural one, the method has an effect to facilitate the growth of the roots of a plant. Thereby, the method is extremely effective for the healthy growth of the potted plant. Since the method is easily performed at a low cost, the application fields are wide, and the method can widely applied not only to the culture of various plants in farmhouses but also to the displays of flowers in flower shops, etc. The watering device is also suitable as a device for culturing a potted plant at home.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom irrigation method and apparatus for pots for the purpose of cultivating plants in flower pots and plants in greenhouses.

[0002]

2. Description of the Related Art Conventionally, potting plants have been cultivated by arranging a large number of pots in a row and supplying water or nutrients from above. In such a method, the solution had to be regularly sprayed, which was troublesome and labor-intensive. There is a method of performing these with an automatic spraying device, but it requires investment in equipment, which leads to an increase in production cost. In order to eliminate these economic and labor inconveniences, a simple irrigation method has been proposed. That is, there is a method in which a mat or a string is soaked with water or a solution and is absorbed into a potted plant by a capillary phenomenon (Japanese Patent Application No. 6-96).
3-98933, JP-A-1-165324, JP-A-2-
174616). Further, an improved method of mat watering in which a mat is installed on an inclined surface and the flowing solution is collected and refluxed is also proposed (JP-A-2-245123).

[0003]

The method in which potted plants are absorbed by the capillarity has a drawback that the soil water content is set higher than in the natural environment. That is, about 50% of the field water capacity of the soil is optimal for the growth of plants, but the water supply method by the capillary phenomenon is about 70% of the field water capacity, and the water content tends to be excessive. Therefore, when the potted plants are shipped and are viewed at home, it becomes difficult to control the water content, and as a result, the plants are killed or putrefy. In addition, when displaying potted plants at a flower shop or the like, few people were familiar with the plant in question, and it took a lot of time to properly water the plant. The present invention solves these drawbacks and proposes a watering method similar to the natural environment for growing and maintaining healthy potted plants.

[0004]

[Means for Solving the Problems] The inventors of the present invention have made extensive studies to find a watering method similar to the natural environment. As a result, the above-mentioned problems can be solved by adding an improvement to the conventional mat or string watering. I discovered that I can do it.
The present invention has been made based on this finding. That is,
The present invention inserts one end and the other end of a string-shaped water absorbing member into a through hole provided in a lid of a watering container to immerse in water for irrigation, and a net-like sheet is brought into contact with an upper portion of the string-shaped water absorbing member, It is a bottom surface watering method for pots, characterized in that the bottom of a flowerpot is brought into contact with a mesh sheet for watering. Further, the invention of the device is to provide two or more through holes in the lid of the irrigation container, introduce one end and the other end of the string-shaped water absorbing member into the through holes of the irrigation container, and immerse in the irrigation water,
A bottom watering device for pots, characterized in that a mesh sheet is placed on the upper part of a string-shaped water absorbing member, and a flowerpot is placed on the sheet.

The irrigation container according to the present invention can be applied to various types of large sized irrigation containers used in greenhouses. The range of plants to which the present invention can be applied is wide, and it can be used from germination of seeds of paddy rice and Japanese mustard spinach to growth of seedlings and ordinary pot culture. The width of the string-shaped water absorbing member is about 1 to 2 cm, and the length is appropriately changed depending on the size of the potted plant to the size used in the house, but the length is preferably 5 to 100 cm. Although a slightly larger through hole is provided in the lid portion of the irrigation container depending on the width of the water absorbing member, a method of directly immersing the irrigation container without providing the through hole may be used. In the house, the method of directly immersing in a watering container is advantageous in terms of production. As the irrigation water, not only water but also solutions prepared by diluting various liquid fertilizers can be used. As the sheet to be placed on the upper part of the water absorbing member, paper such as ginseng, peat moss, cloth and newspaper can be used. The string-shaped water absorbing member used in the present invention is preferably made of a material such as gauze that easily absorbs water.

[0006]

The water absorbing member introduced into the through hole of the water container absorbs water or nutrient solution from the irrigation water and supplies it to the upper portion. Since there is a sheet between the water absorbent member and the flower pot, when the potted plant really needs water without the capillary water penetrating directly into the soil in the pot, only the necessary amount of water from the water absorbent member to the soil is reached. Supplied. The plant will actively take root because the soil will not become over-humidified.

And On the upper part of the string-shaped water absorbing member, the cheesecloth sheet 8 corresponding to the lid portion of the irrigation container was placed, and further the flowerpot 9 was placed (FIG. 1). The irrigation container 1 was filled with tap water. In this state, cyclamen were cultivated for 4 weeks. Since there is a ginseng between the water absorbent and the flower pot, when the potted plant needs water without capillary water directly infiltrating the soil in the pot,
Only the required amount of water was supplied to the soil. After 4 weeks, the upper, middle, and lower layers of soil were sampled and the soil water content was measured. Table 1 shows the results of the soil moisture as a percentage (%) with respect to the maximum field water capacity. Cyclamen was similarly cultivated by conventional string irrigation for 4 weeks, and then the soil water content was measured, and the results are shown in Table 1.
