不便も生じていた。Technical background of the invention and its problems Traditionally, at home, the suitability of moisture in potted soil in which garden plants were planted was confirmed by observing the soil surface with the naked eye or by touching the soil surface with one's hands. It was getting worse. However, this method has the problem of not being able to accurately sense moisture depending on the person taking the measurement or the type of soil, which may cause the cultivated plants to wither and die. In addition, touching the soil directly with one's hands caused inconveniences such as getting one's hands dirty.

ことは難かしいという問題点があつた。 On the other hand, plant cultivation specialists and researchers measure soil moisture using moisture measuring instruments such as tensiometers, dry-dry methods, and electrical resistance moisture meters. However, although these methods can accurately measure moisture, they require a long time to measure or require the preparation of expensive measuring instruments, making it difficult to carry out these methods at home. The problem was that it was difficult.

硬質PVC板にアクリル系接着剤により貼着した。Example 1 (1) Manufacture of soil moisture sensing station 20g of cobalt chloride, 30g of acrylic emulsion
g was dissolved or dispersed in 100 g of water. A Watzmann filter paper (width: 1 cm, length: 10 cm) was immersed in the aqueous solution for 5 minutes, and then dried at 100° C. for 24 hours to produce a moisture-sensing paper. This moisture sensing paper was attached to a stick-like hard PVC board using an acrylic adhesive.
(2) 土壌水分感知ステイツクの性能

下の結果を得た。(2) Performance of the soil moisture sensing station When watering an ornamental plant (caladium) planted in a No. 7 pot under the growing conditions of temperature 20℃ and RH 60%, the soil moisture sensing station is inserted into the soil and the moisture is detected. When observing the discoloration of the sensing paper, the following results were obtained.
第１回灌水後 １日 濃赤色
〃 ３日 淡赤色
〃 ７日 青色
第１回灌水後、土壌水分感知ステイツクが青色
になつた時に第２回の灌水をした。以後同様に青
色になつた後に灌水して１カ月間育成を続けた。 After the first irrigation: 1 day dark red 〃 3 days light red 〃 7 days blue After the first irrigation, when the soil moisture sensing station turned blue, the second irrigation was carried out. Thereafter, after the seeds turned blue, they were watered and continued to grow for one month.
観葉植物は元気であつた。 The houseplants were healthy.
比較例 １
肉眼観察および指触により鉢土が白ぽく乾燥状
態になつたと認められた時に灌水する他は、実施
例１と同様にして観葉植物を育成した。Comparative Example 1 A foliage plant was grown in the same manner as in Example 1, except that watering was performed when the potted soil was found to be whitish and dry by visual observation and finger touch.
観葉植物は約１ケ月後に枯死した。 The ornamental plants died after about a month.
鉢土の表面観察では、その内部の土壌水分の判
断が適確にできないためと思われる。 This seems to be because observing the surface of potted soil does not accurately determine the soil moisture inside.
比較例 ２
毎日１回灌水をする他は実施例１と同様にして
観葉植物を育成した。Comparative Example 2 A foliage plant was grown in the same manner as in Example 1, except that it was watered once a day.
観葉植物は約１ケ月で枯死した。 The ornamental plants died in about a month.
常に鉢土に水が充満しているため植物の根が酸
欠状態になつたためと思われる。 This is probably because the roots of the plants are starved of oxygen because the potting soil is constantly filled with water.
