BACKGROUND OF THE INVENTION
The present invention relates to a plant growth promotion method and a plant growth promoter composition, and more specifically, a method for promoting the growth of plants by generating capillary roots in the roots by oxidizing the roots of the plants. And a plant growth promoter composition.
[0002]
[Prior art]
Conventionally, agricultural chemicals are sprayed to prevent plant diseases and control pests in the soil. However, since residual agricultural chemicals adversely affect the human body, so-called agricultural chemical-free agriculture that does not use agricultural chemicals has recently been recommended.
[0003]
[Problems to be solved by the invention]
The present inventor has conducted research on plant disease preventives and pest control agents that replace pesticides, and found that by applying hydrogen peroxide water instead of pesticides, it is possible to prevent plant diseases and control pests in the soil. did.
[0004]
When hydrogen peroxide is applied to prevent plant diseases and pests in the soil, the subsequent plant growth is better than when pesticides are applied. It was thought that it was due to efficient removal.
[0005]
Then, when this inventor observed the root immediately after hydrogen peroxide solution was applied, it discovered that the surface of the root was oxidized and was damaged. Furthermore, when the roots on the third day after application were observed, it was found that a large number of capillary roots were generated from the surface of the damaged roots.
The present inventor conducted an experiment to oxidize the surface of plant roots using potassium permanganate or sodium percarbonate in order to investigate whether the same thing occurs with other oxidizing agents. It was found that a large number of capillary roots were generated from the surface of the damaged root.
[0006]
Furthermore, when plant nutrients such as sugars and amino acids are mixed with potassium permanganate or sodium percarbonate and applied to plants, the growth of the plant may be promoted compared to simply applying nutrients. found. The present invention has been made based on these findings.
[0007]
Therefore, an object of the present invention is to oxidize plant roots to generate capillary roots in the roots, thereby promoting plant growth.
It is another object of the present invention to provide a plant growth promoter composition that oxidizes plant roots to generate capillary roots in the roots, thereby promoting nutrient absorption.
[0008]
[Means for Solving the Problems]
The means of the present invention taken to achieve the above object are as follows.
In the first invention,
A method for promoting plant growth, comprising:
Oxidizing and damaging the roots of plants to generate a large number of capillary roots from the surface of the damaged roots, promoting the absorption of nutrients ,
This is a method for promoting plant growth.
[0009]
In the second invention,
A method for promoting plant growth, comprising:
Oxidizing and damaging the roots of plants with an oxygen generator to generate a large number of capillary roots from the surface of the damaged roots, promoting the absorption of nutrients ,
This is a method for promoting plant growth.
[0010]
In the third invention,
In the plant growth promotion method according to the second invention, the oxygen generator is one or more selected from potassium permanganate, sodium percarbonate, sodium perborate, or hydrogen peroxide. is there.
[0014]
In the present invention, the nutrient is able to help the growth of agricultural products by being dissolved in water or dilute acid when sprayed on soil or the like (including water and culture substrate in the hydroponics method in this specification). It refers to a composition that becomes ions and can be absorbed into the body from the roots of agricultural products to promote the growth of crops.
The oxygen generator refers to a composition that contains hydrogen peroxide therein, and the hydrogen peroxide serves as a catalyst to generate oxygen. When this oxygen generating agent is sprayed on soil or the like, it generates an appropriate amount of oxygen, and the crop can absorb the oxygen from the roots to promote growth.
[0015]
The ammonium salt refers to ammonium hydrogen carbonate, ammonium chloride, ammonium nitrate, ammonium sulfate, and the like, and the potassium salt refers to potassium chloride, potassium sulfate, and the like.
Furthermore, amino acids may be decomposed from other objects. In this case, soy sauce can also be used when the contained components are clear and contain moderate amounts of amino acids. Sugars may be decomposed by microorganisms. For fructose, sucrose, etc., usually used are high-concentration waste sugar, brown sugar and the like. Among saccharides, it is preferable to use glucose, fructose, sucrose and the like which are most easily absorbed from the roots of agricultural products.
Nucleic acids may be decomposed from other objects.
[0016]
(Work)
Oxidation of plant roots initially oxidizes and damages the surface of the roots, but afterwards many capillary roots are generated from the damaged root surface, and these capillary roots efficiently absorb nutrients in the soil Therefore, growth can be promoted.
In addition, by using slaked lime, it is possible to create an environment in which effective microorganisms in the soil are likely to increase.
[0017]
The saccharide to be sprayed is preferably glucose, fructose, sucrose or the like, which is substantially the same component as the saccharide inside the root, which is an energy source for absorbing nutrients from the outside. As a result, the sprayed saccharide has good affinity with the saccharides present in the roots of the agricultural products, is efficiently absorbed by the roots, and becomes an excellent nutrient in the body of the agricultural products.
[0018]
When slaked lime and an oxygen generator are sprayed, the slaked lime creates an environment in which effective microorganisms that decompose organic matter are likely to increase, and the oxygen generator oxidizes the root surface and easily absorbs nutrients.
[0019]
When the composition for promoting the growth of a crop according to the present invention is mixed with compost, the slaked lime contained in the composition for promoting the growth increases the number of effective microorganisms in the compost, and due to the strong oxidizing power of potassium permanganate or Assisting the growth of aerobic bacteria in effective microorganisms by oxygen generated by oxygen generator. As a result, this compost becomes fully ripe compost, and when this compost is applied to the field, a good harvest can be obtained.
[0020]
[Example 1]
The soil contains components that perform various functions, and many microorganisms are constantly carrying out metabolic activities. When the growth test of agricultural products in such a soil is affected by the components and microorganisms contained in the soil, the effects of the chemicals used in the control plot and the present invention are not straightforward in the soil. It is possible that there is.
Therefore, in Examples 1 to 4 below, the chemicals used were each hydroponically cultivated less susceptible to other components and microorganisms.
[0021]
