Abstract

PURPOSE:To prepare a soil conditioner which improves the air passability, water-holding property, and fertilizer-holding property of soil and promotes the growth of crops by compounding a specific fermentation liq. with charcoal. CONSTITUTION:A lactic acid fermentation liq. (e.g. one obtd. by culturing lactic acid bacteria in a culture medium contg. an yeast extract, peptone, and glucose and separating the resulting cells with a centrifuge) is compounded with charcoal pref. in an amt. of 0.01-10wt.%.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil improver for agriculture and horticulture. The soil conditioner of the present invention is used for agriculture, horticulture, lawn cultivation, etc. and exhibits the effect of fertilizer to enhance plant vitality.

[0002]

2. Description of the Related Art Conventionally widely used agricultural chemicals such as BHC and parathion and various synthetic chemical fertilizers are highly toxic to humans and animals.
It is becoming a social problem as pesticide pollution. Therefore, there are various movements of opposition movements and regulations from the viewpoint of conservation of natural environment and protection of ecosystem. For example, it has been pointed out that such chemical substances may flow into the water sources around the golf course and pollute the water supply, and there are also public movements to reduce the use of pesticides and chemical fertilizers. In addition, cases of dermatitis occurring in golf course caddies and course keeper due to heavy use of chemical fertilizers were reported, and problems such as pesticides and fertilizers used at the time of cultivation being ingested by the human body while attached to the crops were also reported. Is also pointed out. For this reason, there is currently a strong demand for pollution-free fertilizers that do not affect the ecosystem.

Conventional organic fertilizers such as oil dregs and poultry manure, and soil improvers give off odors when applied to golf courses and the like.
It is also not good in terms of aesthetics.

An object of the present invention is to provide a soil conditioner which has little influence on the ecosystem and has excellent odor and aesthetics when applied.

[0005]

The present invention provides a soil conditioner characterized by containing a lactic acid fermentation liquor and charcoal.

The lactic acid fermentation broth used for the soil conditioner of the present invention is a lactic acid fermentation broth obtained by lactic acid fermentation using a lactic acid bacterium against a medium containing enzyme extract, peptone, glucose and the like, or from this. It may be a lactic acid fermentation separated liquid obtained by removing the cells of lactic acid bacteria with a centrifuge, a separation membrane or the like. These lactic acid fermentation liquids or fermentation separation liquids contain various metallic elements such as proteins, sugars, P, Ca, Na and K, various amino acids, and vitamins,
It contains organic acids such as lactic acid, phosphoric acid, citric acid, and formic acid, and contributes to the growth of crops.

On the other hand, as charcoal, conventionally known charcoal,
Wood pulverized coal is particularly preferable, and it is also preferable to use wood coal made from waste materials as a raw material from the viewpoint of resource conservation. The amount of wood charcoal blended in the soil conditioner is preferably 0.01 to 10% by weight.

By blending such charcoal, the water retention and water permeability of the soil are greatly improved and good drainage is achieved. Further, since charcoal has a large adsorption area, it has a high deodorizing effect and the fermentation odor is reduced. Furthermore, bacteria such as Azotobacter that fix nitrogen are easily settled on charcoal, which is preferable for growing crops. In addition, charcoal is alkaline, has a high soil-improving effect, and absorbs solar heat, thus contributing to an increase in soil temperature and promoting the growth of crops. In addition to the above components, nitrogen, phosphoric acid, potassium and the like may be added to the soil conditioner of the present invention.

To prepare the soil conditioner of the present invention using these components, a lactic acid fermentation liquor or its separated liquid and wood powder coal, and if necessary, nitrogen, phosphoric acid, potassium, etc. are mixed and homogenized. Stir with a Genizer. The particle size of charcoal is preferably 50 mesh (300 μm) or less in consideration of the case where a sprayer is used.

When using the soil conditioner of the present invention, 1
It is diluted about 0.00 to 4000 times and sprayed on crops at a rate of 0.5 to 10 L / m ² once every 3 to 20 days in a watering manner.

The soil improver of the present invention promotes rooting and increase of chloroplasts, and is effective not only for growing grass on golf courses but also for home gardening, greenhouse cultivation, paddy field, and afforestation. In particular, vegetables such as radish, mizuna, taro, small potatoes, tomatoes, flowers such as cornflower, eustoma, foliage plants such as pothos, yucca, dracaena, radish sprouts, sprouts,
It is effective for hydroponics such as melon.

[0012]

According to the soil conditioner of the present invention, the lactic acid fermentation liquor exhibits a plant activating effect, and charcoal removes and reduces the odor of the lactic acid fermentation liquor.

EXAMPLES Next, the present invention will be described more specifically based on examples.

[Example] Yeast extract 2%, peptone 2
% Lactobacillus (Enterococcus faecium S) in 1000 L of medium containing 10% glucose
HO-31) was cultured for 12 hours. Culture temperature is 37 ℃, 6N
The pH was adjusted to 7.0 with NaOH.

The broth was separated from the culture solution at 8000 G using a continuous centrifuge to obtain a lactic acid fermentation separated solution. 0.4% of wood dust coal was added to this lactic acid fermentation separated liquid, and the mixture was pulverized and stirred for 5 minutes with a homogenizer.

The obtained separated liquid was diluted 1000 times and sprayed on each crop at a rate of 6 L / m ² once every two weeks immediately after sowing. Water was sprayed at the same rate as a control. The results are shown in Table 1.

The soil improver of the present invention is easy to prepare and improves the air permeability, water retention and fertilizer retention of soil to promote the growth of crops. Further, it can be used not only as a basic fertilizer but also as an additional fertilizer by simply spraying it on the soil even during the growth of crops and turf, and the soil can be easily organized. Furthermore, according to the soil improving agent of the present invention,
Agrochemical-free cultivation that does not contain chemically synthesized components can be performed,
Since it has little impact on the ecosystem, it is suitable for cultivating turf on golf courses and farm crops. Further, it is suitable for turf and the like on a golf course, since it does not impair odor generation and aesthetics.
