Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides a soil conditioner for plant cultivation containing hydrated halloysite and/or ranklite;
The present invention relates to a soil improvement agent for plant cultivation using natural products humic acid and hydrated halloysite, a soil improvement agent for plant cultivation containing chicken manure and/or oil dregs, and a method for producing the same.

0002

[Prior Art] When cultivating plants such as vegetables, grains, fruit trees, garden plants, and lawns, roots and stems are damaged by the larvae and adults of planthoppers, grasshoppers, fall armyworms, snail moths, tsutomo, scarab beetles, honey beetles, crane flies, earthworms, locusts, etc. Damage caused by leaf feeding. Conventionally, as a method for controlling pests such as planthoppers, moths, and scarab beetles, agricultural chemicals such as Calphos emulsion, Ortolan hydrating agent, Garcidon, EPN, Tocthione diazinon, Salithion, Sumithion, Diplex, and DDNP have been sprayed.

However, these methods of spraying pesticides have the disadvantage that a large amount of pesticide must be sprayed on larvae living underground in order for the pesticides to reach the larval bodies.

[0004] For adult insects that have appeared on the ground, pesticides must be sprayed more often as they fly and move, and it is also necessary to spray a large amount of pesticides.

[0005] In recent years, the contamination damage caused by these agricultural chemicals to underground water, river drinking water, rice fields, and fish ponds has been attracting attention.

[0006] For this reason, soil injection machines that efficiently introduce pesticides and attractants that do not use pesticides have been developed, but both have the disadvantage that they can only exert local effects.

[0007]

OBJECTS OF THE INVENTION An object of the present invention is to find a method for controlling a wide range of pests that are harmful to the growth of plants without polluting the environment.

[0008]

[Means for Solving the Problems] Surprisingly, the present inventors have discovered that hydrated halloysite and/or rank light activate hair roots of plants, thereby promoting the growth of tap roots, crown roots, branch roots, root hairs, etc. of plants. I have found that it can be promoted.

Furthermore, the present inventor has discovered that a soil conditioner for plant cultivation consisting of humic acid and/or humic acid extract, and hydrated halloysite and/or ranklite can be used to improve the growth of plant roots, crown roots, branch roots, root hairs, etc. It has been found that in addition to promoting growth, it suppresses the influence of pests that feed on roots, exhibiting an excellent promoting effect on plant growth, and solving the above problems.

[0010] The present inventor further provides chicken manure and/or oil scum impregnated with humic acid and/or humic acid extract;
A soil conditioner for plant cultivation consisting of lime and hydrated halloysite and/or ranklite shows similar effects;
Furthermore, it has been found that the soil conditioner of the present invention also functions as a fertilizer due to the presence of chicken manure and/or oil scum.

[0011] In addition, lime such as slaked lime and quicklime undergoes a neutralization reaction with humic acid, generating heat of 40 to 60°C, and converting chicken manure, oil scum, contrast, activated sludge, etc. into organic fertilizer (decomposition, drying).
Surprisingly, I discovered that this can be accomplished in about an hour. This soil conditioner is made alkaline by lime and works to make the soil alkaline.

The hydrated halloysite or rankrite used in the present invention acts to activate hair roots of plants and promote the growth of tap roots, crown roots, branch roots, root hairs, etc. Therefore, even these alone can achieve excellent soil improvement effects. These are obtained by collecting natural ores of hydrated halloysite or rankrite using a power shovel, a conventional excavator such as a Yunbo, drying and pulverizing them, and using the powder as a powder having a mesh size of 30 to 100 and a water content of 60% or less.

[0013] The humic acid used in the present invention exhibits a bactericidal effect on soil, as well as a deodorizing effect on chicken manure and oil scum and an effect on promoting their decomposition. Furthermore, when lime is used, as mentioned above, it functions to generate heat through a neutralization reaction with the lime. Humic acid can be sourced from natural humic acid, recycled humic acid and soil humic acid.

[0014] Natural humic acid and an extract of natural humic acid are obtained by extracting young coal such as lignite, peat, and brown coal with an alkaline aqueous solution such as sodium hydroxide, potassium hydroxide, slaked lime, or ammonia, and then adding the extract to sulfuric acid or hydrochloric acid. The natural humic acid extract used in the present invention is obtained by preparing an aqueous solution with a pH of 8 to 3 with an inorganic acid such as nitric acid or phosphoric acid.Furthermore, by adding the above-mentioned inorganic acid to this extract until the pH reaches 3 or less, humic acid is extracted. Precipitate the acid. This can be filtered and dried to obtain the natural humic acid used in the present invention.

[0015] Regenerated humic acid and the extract of regenerated humic acid are obtained by oxidizing coal or pitch with nitric acid, and extracting the oxidized product with an aqueous alkali solution such as sodium hydroxide, potassium hydroxide, slaked lime, or ammonia. The regenerated humic acid extract used in the present invention is obtained by converting the liquid into an aqueous solution with a pH of 8 to 3 with an inorganic acid such as sulfuric acid, hydrochloric acid, nitric acid, or phosphoric acid.
Furthermore, humic acid is precipitated by adding the above-mentioned inorganic acid to this extract until the pH reaches 3 or less. This can be filtered and dried to obtain regenerated humic acid used in the present invention.

[0016] Soil humic acid and soil humic acid extract are used to remove humus soil, which has been accumulated by aqueous or terrestrial plants and has been corroded by soil bacteria over a long period of time, by using an ejector, a yunbo, a power shovel, or a submersible pump. The soil humic acid extract used in the present invention can be obtained by collecting the humic acid using a common excavator such as the above, crushing it, drying it, and extracting it as an acidic aqueous solution having a pH of 3 to 6.

The lime used in the present invention is slaked lime or quicklime, and as mentioned above, has the function of neutralizing humic acid,
Significantly accelerates the conversion of chicken manure and/or oil residue into organic fertilizer,
It also works to make the soil alkaline and prevent insects such as scarab beetles from attaching to plants. Of course, it also works to make acidic soil alkaline.

[0018] The soil conditioner of the present invention contains humic acid and/or
Or humic acid extract with hydrated halloysite powder and/or
Alternatively, the present invention also covers a manufacturing method by adding Lancrite powder.

The soil conditioner produced in this way promotes the growth of the tap root, crown root, branch roots, root hairs, etc. of plants, suppresses the influence of pests that feed on the roots, and provides excellent plant growth. It has a promoting effect. In addition, by impregnating humic acid into chicken manure and/or oil scum, causing a neutralization reaction, and mixing lime and hydrated halloysite and/or rankilite powder in any proportion, it can be used as an organic fertilizer for plant growth. It has been found that the root promoting effect can be enhanced.

Therefore, the present invention involves adding humic acid and/or humic acid extract to chicken manure and/or oil residue, adding lime to make an alkaline organic fertilizer, and adding hydrated halloysite powder and/or ranklite to this. The present invention also relates to a method for producing the above-mentioned soil conditioner for plant cultivation, which comprises adding powder.

[0021] The content of chicken manure and/or oil scum in the soil conditioner is 1 to 30% by weight based on the entire conditioner.
It is.

The soil conditioner thus obtained usually contains humic acid in a proportion of 10 to 100%.

[0023] The soil conditioner of the present invention is applied to 1 to 30 cm underground in areas where plants such as vegetables, grains, fruit trees, garden plants, and lawns are cultivated.
Sprayed over 200 m long and used with tractors, plows, hoes, shovels, etc., it promotes the development of tap roots, crown roots, branch roots, root hairs, etc., suppresses the influence of pests that damage roots, and is an excellent promoter of plant growth. be effective.
