Detailed Description of the Invention

[0001]

[Industrial application] The application of calcium fertilizer to plants.

[0002]

2. Description of the Related Art Conventionally, calcium has been supplied to plants mainly by applying fertilizers such as lime fertilizer and fertilizers mainly containing calcium phosphate. Calcium is one of the nutrients of plants, and it is so important that it is said to be four elements of fertilizer together with nitrogen, phosphoric acid and potassium. However, traditionally calcium has been to improve acidic soil rather than to meet plant requirements. Therefore, calcareous fertilizer is called indirect fertilizer, unlike the other three elements.

This calcium is absorbed from the soil by the roots into the plant body and is said to have the following fertilizing effect. 1. It is involved in the growth and development of plants by the protein synthesis from nitrate nitrogen absorbed in the plants. 2. It is adsorbed to the cytoplasm and acts as a protective collagen. 3. It binds to pectic acid in the middle lobe between cells to form calcium pectate, which hardens the tissue. 4. It assists normal physiological actions by neutralizing organic acids produced by metabolism in leaves and the like. 5. It is involved in the transfer of sugars and assists the transfer of carbohydrates synthesized in leaves to the fruit.

Deficiency of such an important calcium that exerts a physiological action causes physiological disorders such as tortuous tomatoes, malformed fruits, mildew, cabbage cabbage, and apple bitter pit (biterpox). Has been confirmed to cause. Therefore, calcium needs to be smoothly absorbed in the plant and translocated.

In the case of tomato, the content of calcium in crops is the largest in leaves, and is small in petioles, stems and fruits, and most of them are used to neutralize excess organic acids in leaves. It is deposited in the leaves and does not move.
Therefore, it is a known fact that the lower leaves have a large amount of calcium.

Among the conventional techniques, for example, Japanese Patent Publication No. 62-28
The fertilizer containing calcium formate as an active ingredient is sprinkled on the leaves 117, whereby calcium is smoothly absorbed from the leaves, which is very effective. Furthermore, formic acid is separated in the plant body into carbon dioxide and water. It has the advantage of becoming effective, effective and not harmful.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention The above-mentioned calcium formate foliar spray is very effective in absorbing calcium,
Although the growth of crops is promoted, the damage caused by pathogens is extremely large during the growth of crops.
It was noted that the effect can be further enhanced by suppressing this. Therefore, an object of the present invention is to prevent the development and growth of pathogenic bacteria attached to plants and to supplement the plants with calcium components.

[0008]

In order to solve the above-mentioned problems, the present invention provides a fertilizer containing calcium formate and calcium propionate. This fertilizer is applied directly to plants or absorbed by plants by a dipping method to prevent the generation and growth of the phytopathogenic fungi in question to form healthy plants and directly supply calcium components to plants. .

This calcium formate has a water solubility of 20 ° C.
At 100 g, 16.6 g was dissolved. It has a pH of 7.02 and is a very suitable compound for plants as an organic acid calcium salt. On the other hand, calcium propionate is a food additive which has been confirmed to be added up to 2.5 g / kg as a fungicide for bread and cake.

Both of these are mixed at an appropriate mixing ratio depending on the plant, and diluted 200-1,000 times with water to dissolve.
For example, this solution is always in the case of cucumber, eggplant, from the flowering stage for grapes, etc., at the time when the physiological action of the plant is activated,
Sprinkle directly on the plants. Further, the fruit from the time when the fruit begins to grow is directly absorbed with the solution by the dipping method.

[0011]

[Effects and effects of the invention] By using calcium formate in combination with calcium propionate, generation and growth of phytopathogenic fungi such as fungi attached to plants are prevented, so that a healthy plant body is maintained and calcium salts are directly added thereto. Since it is absorbed, it is absorbed by the physiological action of the pericarp and the leaf surface, sufficient demand for calcium is satisfied, and efficient fertilization can be obtained.

[0012]

[Example] Calcium propionate is mixed with calcium formate in a ratio of 1: 1 and diluted with water 500 times to dissolve. After this seedling was transplanted to tomatoes and spread three times a month after they were established, the results showed that the tomatoes had good fruiting and growth, and the occurrence of ruffled and malformed fruits, which is said to be calcium deficiency, and the occurrence of mold disease. Without a very good harvest. Also for grapes, after flowering with the above solution, the seedlings were sprinkled and soaked three times a month, and no fruiting bacteria were found, and smooth fruiting was observed. In this way, by using a mixed solution of calcium formate and calcium propionate, there is no occurrence of pathogenic bacteria, which has been a problem in the past, and physiological supplementation of calcium prevents healthy growth, resulting in a very high-quality harvest. Was obtained.
