JPH04300808A - Plant growth promoter - Google Patents

Abstract

PURPOSE:To obtain a harmless plant growth promoter having extremely remarkable plant-growth action and effective for remarkably improving the quality of the plant by adding a sugar such as sucrose and a carbonate such as sodium carbonate to iodine. CONSTITUTION:Iodine and potassium hydrogen iodate are mixed and dissolved in boiling water. The potassium hydrogen iodate acts as an agent for promoting the dissolution of iodine in water. Separately, a sugar such as sucrose or glucose is added to boiling water and dissolved under heating and sodium carbonate is added to the solution after complete dissolution of the sugar. Sodium metasilicate is added to the solution to make the solution spreadable on the crops in scattering. The objective plant growth promoter containing iodine, sugar and carbonate as active components is produced by this process. The amounts of the sugar and the carbonate are preferably >=35 pts. and >=3.5 pts. based on 1 pt. of iodine, respectively.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a growth promoter for plants, especially agricultural crops.

0002

BACKGROUND OF THE INVENTION Traditionally, agricultural crop cultivation systems have focused on high efficiency and mass production, which is how to increase the yield per unit area without worrying too much about quality. However, in recent years, with the modernization of agricultural technology, the cultivation system has begun to take into account the trend toward high-quality production, which focuses on how to produce products of even better quality.

Under these circumstances, plant hormones (
For example, auxin) has been used.

0004

[Problems to be Solved by the Invention] However, plant hormones have problems such as weakening the vigor of the tree when used repeatedly, and for example, when auxin is used to enlarge fruits etc., the cells themselves become larger. There have been problems such as the inability to produce so-called fruit that is full of fruit.

The present invention was devised in view of the above points, and its purpose is to provide a plant growth promoter that further promotes the growth of agricultural products and further improves their quality. be.

[0006]

[Means for Solving the Problems] As a result of examining various plant growth factors from the above-mentioned viewpoint, the present inventor focused on iodine in particular, since thyroid hormone, which contains a large amount of iodine, has a great effect on the growth of animals. I ended up doing it.

[0007] By the way, iodine has not been recognized as a very necessary element for higher plants, and it is widely known that it is rather highly toxic. However, there are reports in the literature that very small amounts of iodine promote the growth of higher plants, and that iodine plays a physiological role in certain salt marsh plants. , Eckloria of the Laminaceae family.
Cava) is also a raw material for iodine, and it is also known from experience that plants that are sprinkled with hot water from Kajime grow faster.

[0008] Based on these examples, the present inventor concludes that there is no doubt that iodine affects plant growth, and that iodine acts as a plant growth factor due to some kind of interaction with other substances. Thoughts and further research
As a result of repeated tests, it was discovered that the addition of sugars and carbonates to iodine causes no harm and has an extremely significant effect on plant growth.

The present invention was made based on the new findings of the inventors as described above, and is a plant growth promoter characterized by containing iodine, saccharides, and carbonates as active ingredients.

Examples of sugars used in the present invention include sucrose and glucose. Further, as the carbonate, sodium carbonate is particularly preferable, and for example, ammonium bicarbonate, calcium bicarbonate, potassium bicarbonate, etc. may be used.

When the plant growth promoter according to the present invention is used for agricultural and horticultural purposes, it basically takes the form of a liquid preparation obtained by dissolving or dispersing it in water. At this time, since iodine is difficult to dissolve in an aqueous solution, it may be possible to add potassium iodate or the like to the agent of the present invention to dissolve iodine. Note that silicate or the like may be added to obtain a spreading effect during spraying.

[0012] The blending ratio (weight) of the components in the present invention varies depending on the method of use, but is preferably 35 or more saccharides and 3.5 or more carbonates per 1 iodine.

[0013]

[Examples] Examples of the present invention will be shown below, but the present invention is not limited thereto in any way.

[0014] In this example, the manufacturing process was as follows.

First, iodine and potassium hydrogen iodate are mixed and dissolved in boiling water. Here, potassium hydrogen iodate was added in order to dissolve iodine in the aqueous solution. Next, sucrose and glucose are mixed into another boiling water and dissolved while heating, and when they are completely dissolved, sodium carbonate is added. Finally, turn off the heating and
After mixing both solutions, sodium metasilicate was added to the mixture. Here, sodium metasilicate was added to obtain a spreading effect on agricultural crops during spraying.

The mixing ratio (weight) of iodine, sugar and sodium carbonate, which are the active ingredients of this example, is approximately 1 iodine to 36 sugars (sucrose: glucose = 1:1) and 3.6 sodium carbonate. there were. The ratio of other ingredients is approximately 1 part iodine to 2 parts potassium hydrogen iodate.
It was sodium metasilicate 3.

Next, a test example of this embodiment as described above will be shown.

<Test Example 1> In a tea plantation in the Chubu district of Shizuoka Prefecture, this example was diluted 300 times with water, and
The results are shown after spraying on the entire surface with a spraying amount of 0l/10a. ◎ Number of buds As a result of spraying in late February, the number of Ichibancha new buds per 20 cm2 was about 57 in the past, but in this example, the average number was 68. ◎ Harvest Amount: Once immediately after sprouting, once before the scheduled harvesting date, and once a week to 3 days before harvesting, in other words, 3 times in total before harvesting.
As a result of spraying twice, the yield of Ichibancha per 10a was 6 times higher than before.
22.5kg, but in this example the average weight is 820.
0 kg, and at its highest it weighed just over 1000 kg. ◎ Amount of amino acids in leaves As a result of spraying a total of three times before plucking, the amount of amino acids in Ichibancha leaves was conventionally 0.3 to 3.0%, but in this example, the average amount of amino acids was 4.0 to 5.0%. %Met. The measurement method was an automatic analysis method. ◎ Sclerophyllization As a result of spraying a total of three times before plucking as described above, in this example, sclerophyllization was prevented by about 20% or more compared to the conventional method. ◎ As a result of spraying the second tea again after picking the first tea, in this example, new buds emerged about 3 to 7 days earlier than before. In addition, as a result of spraying 500 times diluted with water immediately after picking the first tea leaves once a week, the yield of the second tea leaves was 1 times lower than before.
Yield increased by 5 to 25%, the unpleasant aroma peculiar to second-grade tea disappeared, and the content of amino acids increased.

<Test Example 2> In a cabbage field, this example was diluted 500 times with water and sprayed over the entire field at a rate of 300 to 400 l/10a. As a result of spraying a total of three times, once every 10 days from one week after planting, in this example, the number of days until harvest was about 3 to 5 days earlier than before. Also,
The leaves that were sprayed 3 to 5 days before harvest were softer and tasted better.

<Test Example 3> In a strawberry orchard, this example was diluted 500 times with water and sprayed over the entire surface of the orchard at a rate of 200 to 300 l/10a. As a result of spraying immediately after planting,
Planting damage was almost eliminated and root establishment was promoted. In addition, as a result of spraying once every 10 days from planting to harvesting of the first fruits, the yield of first fruits per 10 a was 2100 kg compared to the previous one.
In this example, the average weight was 2,520 kg, and the sourness was removed and the sweetness increased. Furthermore, after the first fruit harvest, 300
As a result of spraying the seeds twice as diluted with water, the second fruit appeared 7 to 10 days earlier than before.

<Test Example 4> In a Wenzhou mandarin orange orchard, this example was diluted 500 times with water, and 700 to 1000 l/10
It was sprayed all over the garden at the amount of a. As a result of spraying after flowering, the yield per 10 a was conventionally 4000 kg, but in this example the average yield was 4850 kg. In addition, the harvest of mandarin oranges is halved in the year following a year of good harvest, which is said to be called a front year and a back year, but when this example was used, the same amount of harvest could be secured every year. Furthermore, as a result of spraying at a rate of every 15 days from after fruiting (usually around May 20th) until the end of July, uniform ball elongation (fruits greatly increased in weight) was achieved.
