Description

The present invention makes fermented organic fertilizer by adding fermented bacterial cells cultured in rice bran, cereal straw etc. to organic waste which is excrement such as livestock, and fertilizes this organic fertilizer deeply in the winter The purpose of the present invention is to promote the growth of crops in the cold season as a soil temperature keeping agent, and in particular, relates to a method for producing organic fertilizer and a fertilization method used for soil temperature maintenance in which the effect is remarkable in facility horticulture.

Cultivation of crops in the cold season of winter, especially in the horticulture, etc. In order to minimize the imbalance due to the temperature difference between the temperature of the underground area where the roots are active and the temperature of the roots, keep the underground part warm or raise the ground temperature There is a need for a suitable organic soil temperature keeping agent. In addition, electric heating heaters using electricity and steam were used to heat the ground to raise the ground temperature, but there was a problem that it was too expensive.

The present invention is intended to promote the growth of crops in the cold season of winter. In particular, the use of this fertilizer makes its effects remarkably appear in facility horticulture and the like. The temperature inside the facility is raised at a low outdoor temperature to maintain the temperature at 25 ° C to 35 ° C so that the crop is easy to grow, and artificially valuable crops are produced. Although the growth temperature is satisfied, the temperature at which the root of the underground part is located is 13 ° C. to 16 ° C., so that the temperature difference between the above-ground part and the underground part is large, which hinders the growth of the crop.

The growth of the above-ground part seems to be smooth, but the temperature of the underground part does not rise. Even if sufficient fertilizer is given enough, the root part's active power and nutrient absorption capacity are insufficient due to insufficient temperature of the underground part. The fertilizer given without being able to go about vigorous growth of the plant cannot be digested and absorbed sufficiently, the nutrients do not reach the above-ground part, and it is impossible to grow sufficiently. Therefore, even if the temperature is about 3 ° C to 5 ° C, raising the underground temperature can increase the growth of crops and greatly improve production.

Conventionally, various means for producing useful organic fertilizer by mixing a carbonaceous substrate such as sawdust with livestock waste such as livestock manure and raw garbage have been proposed, but the purpose is to raise the soil temperature. There is no organic fertilizer.

An object of the present invention is to make an organic fertilizer suitable for maintaining the ground temperature in winter, and to apply the organic fertilizer deeply in the ground in winter to promote the growth of crops in the cold season as a soil temperature maintaining agent.

In order to solve the above problems, the present invention, as described in claim 1, fermented cells obtained by culturing actinomycetes in rice bran, cereal rice bran, etc., on organic waste mainly composed of livestock excreta, After mixing and stirring the charcoal or bamboo charcoal powder, or the organic fertilizer fermented at about 60 ° C to 70 ° C with the addition of coffee lees, the whole water is added while adding and diluting a 5% to 10% dilution of molasses. Mixing and stirring while adjusting so that the moisture content that is most easily fermented is about 60%, and then fermenting at a fermentation temperature of about 60 ° C to 70 ° C for about 3 to 10 days, and then about 15 ° C to 20 ° C. It is an organic fertilizer characterized by being naturally cooled to the extent that it is in a powder state with a moisture content of about 35%.

Moreover, as described in claim 2, the mixing ratio of the organic fertilizer raw material is based on weight,
・ 43% by weight of organic waste mainly composed of livestock excreta
-29% by weight of fermented cells cultured in rice bran, cereal bran, etc.
The organic fertilizer according to claim 1, wherein the powder of charcoal or bamboo charcoal is 29% by weight, or the coffee cake is 29% by weight instead of charcoal or bamboo charcoal.

In addition, as described in claim 3, the organic fertilizer is fertilized to the bottom of a fertilization groove dug in a field by a thickness of about 10 cm to 15 cm, and lightly soiled to such an extent that the organic fertilizer cannot be seen, and further ripened The mixed fertilizer and the field soil are uniformly mixed to about 1: 1 and covered with a thickness of about 10 cm to 15 cm. The fertilization method using the organic fertilizer according to claim 1 and claim 2 is characterized.

By applying the organic fertilizer of the present invention to the soil, the retention of oxygen and moisture in the soil is increased, and by further applying the same application, the moisture and oxygen in the soil are appropriately contained, resulting in a water shortage of about 35%. The microorganisms in the organic special soil temperature keeping agent in the state can be activated to start fermentation and increase the soil temperature. In addition, because it contains a lot of organic corrosive substances, it can soften the soil, promote the growth of roots according to the growth of crops, and increase the absorbability of fertilizing ingredients. .

In the best mode of the present invention, fermented cells mainly composed of actinomycetes cultivated in rice bran, cereal meal, etc., and charcoal or bamboo charcoal powder are added to organic waste mainly composed of livestock excrement The organic fertilizer fermented at 60 ° C to 70 ° C is further mixed with a 5% to 10% dilution of molasses, and the entire mixture is mixed while adjusting to a moisture content of about 60% that is most easily fermented. Stir. Then, after fermenting at a fermentation temperature of about 60 ° C. to 70 ° C. for about 3 to 10 days, an organic fertilizer that is naturally cooled to about 15 ° C. to 20 ° C. and made into a powder state with a water content of about 35% is generated.

To produce organic fertilizer for the purpose of maintaining the soil temperature of the present invention, 45 kg of organic fertilizer fermented with organic waste, which is excrement of livestock, etc., and fermented cells cultured in rice bran, cereal straw, etc. Add 30kg of charcoal or bamboo charcoal powder, or 30kg of coffee cake instead of charcoal or bamboo charcoal powder, and add about 40L of dilute solution containing 5g% -10g% molasses. The water content of the whole mixture is adjusted with mixing and stirring so that the water content at which it is most fermentable is about 60%. Since fermentation begins in about 8 hours, it is fermented at a temperature of about 60 ° C. to 70 ° C. for about 5 to 10 days. After that, it is naturally cooled and suitable for maintaining a ground temperature in a smooth powder state with a water content of about 30 to 35%. Organic fertilizer can be produced.

And when the mixing ratio of the organic fertilizer raw material is converted on a weight basis,
・ 43% by weight of organic waste mainly composed of livestock excreta
-29% by weight of fermented cells cultured in rice bran, cereal bran, etc.
-The charcoal or bamboo charcoal powder is 29% by weight, or the coffee cake is 29% by weight instead of charcoal or bamboo charcoal.

Then, an experiment was conducted by applying fertilizer to a cultivated field of about 10 tsubo to determine whether the organic fertilizer suitable for maintaining the ground temperature is effective in increasing the ground temperature of the field and maintaining it. A groove with a length of about 10 cm to 15 cm is formed at the bottom of the groove with a smooth organic fertilizer with a moisture content of about 35%, which is dug into a groove having a length of 5 m, a width of 20 cm, and a depth of 18 cm. The length was about 20 cm and 5 m. Cover the soil so that the organic fertilizer that keeps the soil temperature is not visible, and mix the well-ripened mixed raw fertilizer prepared in advance over the soil with a length of 5 m, a width of 20 cm, and a thickness of 10 cm to 15 cm. The fertilizer was applied by mixing and stirring evenly about 1: 1. A week later, vegetable seedlings were planted.

One week after fertilization, the temperature of the organic fertilizer holding the soil temperature was measured, and the temperature rose to 23 ° C. When the temperature of the nearby soil is measured, it shows 16 ° C. Apparently, the organic fertilizer of the present invention maintained the earth temperature was able to confirm the temperature rising effect as the earth temperature maintaining agent. The ideal moisture content of organic fertilizers that maintain the soil temperature is most preferably about 50% when it is desired to maintain the temperature, and more than 60% is likely to lower the temperature. You should be careful.
