Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant growth agent and a method for growing plants, the purpose of which is to make a strong plant resistant to pathogens, molds, etc., and to efficiently grow leaves, fruits, etc. It is intended to provide a plant growth agent and a plant growth method that are safe for.

[0002]

2. Description of the Related Art Conventionally, agricultural chemicals such as various fungicides and insecticides have been used to keep plants healthy. However, although these pesticides have a certain effect of controlling pathogens and pests and keeping plants healthy, especially when used in crops, the pesticides applied to these crops may adversely affect the health of people. It was More recently, it has been a problem that excessively applied agricultural chemicals contaminate water systems and the like, which is one of the major causes of environmental damage.

Further, various fertilizers, nutrients for plants, etc. are used as growth agents for enlarging leaves and fruits. Among these various fertilizers, there are chemical fertilizers, natural fertilizers such as compost, various fertilizers such as fertilizers in which microorganisms useful for porous bodies such as pulverized coal and zeolite are propagated, or nutrients containing growth hormone and the like. However, these were all growth agents that were sprayed on the soil to absorb nutrients from the soil. These growth agents are not absorbed by the root because the nutrients applied are absorbed into the soil and are not absorbed by the roots, or even if they are absorbed, they are a part of the applied amount, or even when the plants are unhealthy. There was a drawback that it was not done. Therefore, these growth agents have not been efficient growth agents that reliably grow leaves, fruits and the like.

[0004]

In view of the above situation, a plant growth agent and a plant growth method that are resistant to pathogens, mold and the like and are strong plants, and that are capable of growing leaves, fruits and the like and are safe for the human body are provided. Creation was desired.

[0005]

The present invention provides 95% by weight.
~ 60 wt% pulverized coal below 100 microns and 5 wt%
Since the plant growing agent is characterized by comprising -40% by weight of water, and the plant growing method is characterized by spraying the plant growing agent on the leaves, the above problems are solved.

The structure of the present invention will be described below.
The plant-growing agent according to the present invention is characterized by comprising pulverized coal having a size of 100 microns or less and water. The pulverized coal used in the present invention is not particularly limited, and specific examples thereof include pulverized coal made from pine, cedar, oak, kunugi, cypress, coconut husk, ogalite and the like.

The particle size of the pulverized coal is preferably 100 μm or less. The reason for this is that pulverized coal having a particle size of 100 microns or less has good adhesion to the leaf surface. Further, the reason for using pulverized coal in the present invention is that pulverized coal is a porous body to create an environment for propagating fungi and microorganisms useful for plants, and it is easy to absorb the light required for photosynthesis, and further harm to plants. Because there is nothing to give. More specifically, the pulverized coal having a porous body provides a three-dimensional breeding site for effective fungi on the leaf surface, and the action of the effective fungi makes the crop resistant to pathogens, molds and the like.

[0008] Pulverized coal also has a function of adsorbing harmful substances such as sulfurous acid gas in the air, nitrogen dioxide, or excessively dispersed pesticides, and protecting plants from the harmful substances. Furthermore, the respiratory action of these propagated microorganisms increases the amount of carbon dioxide on the leaf surface, activates photosynthesis, and increases carbohydrates. Therefore, although the effect of this plant-growing agent may vary depending on the plant to which it is sprayed, the fruits are enlarged and the sweetness is increased, the leaves are grown lushly and strongly, and the germination time of the plant is accelerated. Or, to extend the activity period of plants (the period of actively activating photosynthesis and establishing new shoots, growing leaves lush, etc.).

The plant-growing agent of the present invention is characterized by containing water. The water used as the water is not particularly limited as long as it does not extremely contain dust and the like, and specific examples thereof include tap water, distilled water, electronic water and the like. The reason for incorporating this water content is to facilitate dispersion in an aqueous solution when diluted with water or the like and sprayed on plants, as will be described later. This water content is 5
40% by weight can be preferably used, more preferably 20% by weight
The degree is desirable.

The plant-growing agent may be mixed with various spreading agents for improving spreading on leaf surfaces, various dispersing agents for improving dispersibility in diluted water, and the like. Bentonite, chito acid, starch, sodium alginate, or surfactants such as polyoxin alkylenes, alkyl sulfates and lignin sulfonates are more preferable because they function both as a spreading agent and a dispersant. In addition, fertilizers, other growth agents such as nutrients for plants, fungicides, insecticides and the like may be appropriately added to the plant growth agent, if necessary.

The method of using this plant-growing agent, that is, the plant-growing method will be described below. If the above-mentioned plant-growing agent is diluted with water about 1000 to 3000 times,
It can be preferably used. At this time, if necessary, the spreading agents, dispersants, other growth agents, fungicides, insecticides and the like described in the above-mentioned plant growth agent may be appropriately blended as necessary. This diluted plant-growth agent is sprayed on the leaf surface using a sprayer or the like. The number of times of spraying may be set depending on the time, the time of day, the crop, etc., and although it cannot be clearly defined, it is usually about 6 to 8 times before the crop is harvested.

The plant growth agent sprayed on the leaf surface adheres to the leaf surface, propagates effective bacteria as described above, and as a result, leaves having resistance to pathogenic bacteria, etc. It activates photosynthesis of plants and the like, and makes leaves and fruits grow large.
