Description

The organic liquid manure with agricultural by-products for agricultural fertilization using agricultural by-products and a method of manufacturing the same

The present invention relates to an organic liquid fertilizer for watermelon tube fertilization and a method for producing the same by using agricultural by-products.

The demand for processed chemical preparations focused on excessive use of pesticides and chemical fertilizers for the rapid development of the industry, increased demand for high quality agricultural products, and improved productivity has been rapidly expanded. It has been widely applied to soil. The conventional farming method, which is mainly grown by chemical fertilizers and pesticides, accelerates salt accumulation in the soil, which leads to the decrease of the intellect and acidification of the soil, and results in the suppression of the final decomposer microorganisms and soil biosystems. It is the main culprit. In addition to the increased use of pesticides to control pests that occur during the growth of plants, in addition to the increased resistance to pathogen control, the simplification and suppression of useful microorganisms in the soil causes a rapid increase in soil pathogens and harmful nematode density. There is a recurring vicious cycle that requires the use of large amounts of pesticides.

In addition, severe salt accumulation due to repeated use of rich organic substances and fertilizers and antagonism of nutrients, resulting in chain failure caused by continuous deficiency of essential nutrients and lack of trace elements, lowers the disease resistance of crops. In addition, poor yields lead to serious problems such as reduced harvests and poor quality and taste. In particular, a large amount of capital is being invested more than necessary for the forces of plants that are not recovering despite the continued application of expensive agricultural materials. There is.

In recent years, with the environmental pollution and the serious problems of crop pollution, the development of farming methods using high-quality organic fertilizer or compost rather than chemical fertilizer or pesticide has spread, and many organic fertilizers have been developed and used. Efforts have been made to improve the compost fermentation methods.

However, despite these efforts, there is a lack of understanding of the root cause of the decline in the intellect and the absence of alternatives, and the intensive use of organic fertilizers and compost used as an alternative to chemical fertilizers differs only in terms of materials, but in view of restoring the soundness of the soil. Esau is deepening another problem similar to chemicals. Most compost raw materials are sawdust, various kinds of gourds, food waste, Chinese medicine sludge, fish meal or livestock meal and natural organic materials mixed with them. In order to manufacture such organic fertilizers, fermentation is required for a long time, excessive equipment is required, and the water quality is contaminated with wastewater according to production.

At present, research on organic fertilizers to replace chemical fertilizers and fertilizers for composting resources has been published, but the compost found through these studies is complicated in the manufacturing process, and the components contained in the fertilizer can be easily obtained by actual farmers. There is a big limitation in industrial use in that it is not a material.

Therefore, the present inventors made efforts to solve the salt accumulation problem of the soil due to the use of chemical fertilizers, environmental pollution problems of livestock manure, and at the same time to produce an organic liquid fertilizer that can be easily produced by farmers who grow watermelons. As a result, after mixing the flour and soybean meal in a ratio of 1: 1, 4 times of water was added to the total weight of the flour and soybean meal, and anaerobic culture was performed for 40 to 90 days to prepare a liquid fertilizer. When the watermelon was grown in the facility house in place of the chemical fertilizer, the present invention was completed by confirming that it had an effect of increasing the growth of watermelon while solving the salt accumulation problem of the chemical fertilizer.

An object of the present invention is to provide an organic liquid fertilizer for environmentally friendly watermelon fertilization, and a method for producing the same, which is formulated with a portion of the flour and soybean meal.

In order to achieve the above object, the present invention provides a method for producing an organic liquid fertilizer for watermelon tube fertilization comprising the following steps.

1) preparing a blend by combining 45 to 55% by weight (w / w) of soy flour, and 45 to 55% by weight (w / w) of soybean meal;

2) diluting the formulation of step 1) four times with water; And

3) Anaerobic fermentation of the diluted formulation of step 2) in direct sunlight for 40 to 90 days.

In addition, the present invention mixes 45 to 55% by weight (w / w) of soybean meal and 45 to 55% by weight (w / w) of soybean meal in the liquid fertilizer prepared from the system powder and soybean meal, and the compound is four times water. After dilution provides an organic liquid fertilizer for watermelon tube fertilization using agricultural by-products characterized in that the anaerobic fermentation in a place away from direct sunlight for 40 to 90 days.

Watermelon fertilizer organic liquid fertilizer containing manure meal and soybean meal according to the present invention shows the effect of increasing the growth of watermelon to the extent comparable to chemical fertilizers, and solves the salt accumulation problem of soil that can be caused by the use of chemical fertilizers At the same time, it can exhibit an excellent watermelon growth effect. In particular, this effect was the most increased watermelon growth when the mixture and soybean meal in a ratio of 1: 1, diluted by adding water four times the total weight of the formulation, and then anaerobic fermentation for 80 days.

< Experimental Example  5> Soil Chemistry Analysis of Organic Liquid Fertilizer for Water Fertilization

<5-1> Soil Chemical Analysis Before and After Using Organic Liquid Fertilizer for Water Fertilization

The use of chemical fertilizers cause a problem of salt accumulation in the soil, and the present inventors have tried to determine if the organic liquid fertilizer for watermelon fertilization of the present invention prepared using agricultural by-products can solve this problem.

In Experimental Example 4, through the chemical analysis of the soil cultivated watermelon, the effect of the organic liquid fertilizer for watermelon fertilization of the present invention on the soil was confirmed. As a result, as shown in Table 14 below, the organic liquid fertilizer (liquid fertilizer of <Example 1>, liquid fertilizer of <Comparative Example 1>, and liquid fertilizer of <Comparative Example 2>) of the present invention was used. So, the chemical properties of watermelon-grown soils tended to decrease pH, EC, NO ₃ -N (nitrogen nitrate) and to increase the overall content of Av.P ₂ O _{5 ,} K, Ca, and Mg before fertilizer application. Could confirm. Comparing the chemical fertilizer and the organic liquid fertilizer for watermelon manure cultivation according to the present invention, the content of NO ₃ -N, Av. P ₂ O _{5 ,} K, Ca, Mg in the soil showed a tendency to decrease. In particular, it was observed that the content of these salts decreased the most in the liquid fertilizer of <Example 1> containing the flour and soybean meal. This means that liquid fertilizers containing manure and soybean meal can reduce salt accumulation in the soil and effectively increase the growth of watermelon (Table 14).

Watermelon fertilizer organic liquid fertilizer according to the present invention by using agricultural by-products such as poultry and soybean meal, can solve the salt accumulation problem of the soil due to the use of chemical fertilizer, solve the environmental pollution and treatment problems caused by livestock manure And, above all, using only agricultural by-products readily available from the farm can be anaerobic fermentation to produce liquid fertilizer, it can be useful as an alternative to chemical fertilizer for environmentally friendly and safe watermelon cultivation.

Claims (5)

1) blending 50% by weight (w / w) of flour, and 50% by weight (w / w) of soybean meal to prepare a blend;
2) diluting the formulation of step 1) four times with water; And
