Description

Eco-friendly fertilizer composition that can promote plant growth and increase yield by mixing hwangchil tree extract derived from natural substances and its manufacturing method MANUFACTURING METHOD THEREOF}

The present invention relates to an eco-friendly fertilizer composition capable of promoting plant growth and increasing yield by mixing hwangchil tree extract derived from natural substances and a method for manufacturing the same.

In crop production, plant diseases are one of the harmful factors that inhibit the healthy growth of plants and are caused by microbial factors such as fungi, bacteria, mycoplasma, viruses, and nematodes. If a plant disease occurs in a large-scale cropping area, not only economic loss occurs due to a significant decrease in yield, but also a serious social problem in terms of food security if there is a disruption in the stable production of staple grains.

Synthetic pesticides have been used as a major means of controlling plant diseases in modern agriculture. However, existing synthetic pesticides have been used in large quantities for many years, accelerating the emergence of drug-resistant pathogens, increasing control costs every year, as well as civic and academic concerns about the toxicity of pesticide residues and disturbance of ecosystems. In solving the problem of drug resistance and simultaneously reducing the amount and frequency of application of synthetic pesticides, comprehensive pest control that focuses on the use of biological pesticides can be a new alternative to conventional farming methods dependent on synthetic pesticides.

Biological pesticides are developed based on natural substances derived from biological materials such as plant extracts or using living microorganisms such as fungi, bacteria, and viruses to control pests. Therefore, biological pesticides are natural products derived from nature, have nature-friendly characteristics, and have the advantage of being less toxic or harmless than synthetic pesticides.

When pesticides are used in agricultural or forestry crops to control undesirable organisms, the useful crops are often damaged to a greater or lesser extent in an undesirable manner per se by the pesticides used. These effects are seen primarily in post-emergence applications in useful crops such as maize, rice or cereals, especially when a significant number of herbicides are used. In some instances, useful plants can be protected against the harmful properties of pesticides to plants by using emollients or antidotes that do not adversely affect the pesticidal activity against harmful organisms.

Due to the recent expansion of eco-friendly farming area, people's interest in eco-friendly agriculture and eco-friendly agricultural products is growing. In particular, the consumption of eco-friendly agricultural products is rapidly increasing due to changes in people's awareness of health and well-being. Therefore, since 2019, the government has been promoting a policy to reduce the use of pesticides and distribute safe agricultural products to the public by strictly applying the Positive List System (PLS) for agricultural products. For the above reasons, there is a trend that the use of pesticides is limited worldwide due to problems with chemical pesticides that are currently used (contamination of soil and rivers, pesticide residues in agricultural products, etc.). Therefore, an alternative to these pesticides is eco-friendly biocontrol using microorganisms, natural enemies or plant extracts. In particular, biocontrol using microorganisms is a microbial pesticide that uses antibiotics or toxins produced by microorganisms to control pathogens or pests, and microbial fertilizers that protect plants by using the antagonism of microorganisms themselves and indirectly promote plant growth. etc. Therefore, most recent studies on plant disease control effects are development of eco-friendly microbial agents using microorganisms having an antagonistic effect on plant pathogens.

The number of eco-friendly microorganism preparations or eco-friendly preparations using specific compounds required in eco-friendly agricultural sites is small, so there is a limit to the control of various pests, and the range of use of the developed preparations is limited to specific diseases or pests, or to the plant itself or to humans It has a bad effect on people, so its use is low. Therefore, in order to simultaneously control diseases or pests as a way to solve this problem, a formulation capable of simultaneously controlling plant diseases and pests is required. Eco-friendly microbial formulations or eco-friendly compound formulations developed so far are limited to specific pest control. Or pest control using eco-friendly compound formulations is a burden on the economic labor force of farmhouses, so there is a need for a drug that can be controlled at the same time.

Interest in biological control agents capable of controlling plant diseases and insects is steadily increasing due to concerns about pests having resistance to chemical pesticides and environmental pollution due to the abuse of chemical pesticides. Biopesticide formulations are obtained from live fungi, bacteria and viruses, while others contain active metabolites. Simultaneous control of pests of plant pathogens and entomopathogenic fungi can be particularly cost effective in sustainable agriculture. Various roles of fungal insect pathogens, which are substances capable of simultaneously controlling plant diseases and pests while promoting crop growth, are very important in research on pest management.

Accordingly, the present inventors continued research to develop an eco-friendly fertilizer composition with excellent plant disease or pest control effects without using chemical components that adversely affect the environment such as surfactants, Hwangchil tree extract, sulfur and sodium silicate. The present invention was completed by discovering that the composition containing the is safe for the human body while having an excellent control effect against plant diseases or pests.

Hwangchil tree powder 10kg was put into 100L of purified water and heated at 100 ° C. for 1 hour to obtain a hwangchil tree extract by heat extraction. The extract was filtered under reduced pressure with Advantec No. 2 (110 mm) filter paper to remove insoluble substances, and then concentrated under reduced pressure at 40° C. using a concentrator equipped with a cooling condenser. In order to completely remove the solvent of the extract concentrated under reduced pressure, 0.5 ℓ of purified water was added to suspend the mixture, and then the hwangchil tree extract was obtained using a lyophilizer. Subsequently, sulfur and sodium silicate were mixed at a weight ratio of 1:2, and then the mixture and hwangchil tree extract were mixed at a weight ratio of 3:7 to prepare an eco-friendly fertilizer composition.

The eco-friendly fertilizer composition of the present invention is "(1) Acute dermal toxicity test of Hwangchilhwang using rats of the Korea Biosafety Research Institute" and "(2) Acute contact toxicity test of bees of the Korea Biosafety Research Institute" and "(3) Korea Biosafety It was confirmed that it is harmless to other organisms as it is derived from natural substances through the "Acute Toxicity Test of Freshwater Fish of Hwangchilhwang" conducted by the research institute.

On the other hand, in the modified example (not shown) of the present invention, it is possible to use a fertilizer having a homogeneous quality by mixing a mixture of hwangchil tree extract, sulfur and sodium silicate using a mixer (not shown). The mixer is a chamber in which a mixture of hwangchil tree extract, sulfur and sodium silicate is supported, a burner disposed on the side of the chamber to heat the chamber, and sensing the surface height of the mixture of hwangchil tree extract and sulfur and sodium silicate in the chamber. A phase sensor disposed inside the chamber, a first stirring unit disposed inside the chamber, and a second stirring unit disposed below the first stirring unit, the first stirring unit and the second stirring unit and an electronic control unit that controls the burner and receives a signal from the phase sensor.

In this case, the first stirring unit moves a first blade, a first shaft forming a rotation axis of the first blade, a first rotation motor rotating the first shaft, and the first rotation motor in a vertical direction. It may include a first step motor to do. In addition, the second stirring unit includes a second blade, a second shaft forming a rotation axis of the second blade, a second rotation motor rotating the second shaft, and moving the second rotation motor in a vertical direction. A second step motor may be included. Furthermore, the first blade and the second blade may be arranged to face each other in a vertical direction.

The mixer may generate a sensing value by measuring the height of the surface of the phase sensor when the mixture of hwangchil tree extract and sulfur and sodium silicate is supported in the chamber. The electronic control unit receives a sensing value from the phase sensor and controls the first step motor so that the first blade is located on the upper side with respect to the central plane in the vertical direction of the surface, so that the first blade and the first shaft The first rotary motor can be moved in a vertical direction, and the second step motor is controlled so that the second blade is located on the lower side with respect to the center plane in the vertical direction of the water surface, so that the second blade and the second shaft The second rotary motor may be moved in a vertical direction. Then, the electronic control unit may control the first rotation motor and the second rotation motor to rotate the first blade and the second blade to rotate in different directions. As a result, in the mixer, vortices in opposite directions are formed on the upper and lower sides of the chamber, respectively, so that stirring efficiency can be increased.

It can be sequentially stacked and arranged (a connecting member can be placed between the first shape memory alloy and the second shape memory alloy).

Therefore, in the present invention, when the temperature in the chamber rises above the first temperature during heating by the burner controlled by the electronic control unit, each of the first blade and the second blade has a length corresponding to the shape deformation of the first shape memory alloy at the end. By increasing the stirring efficiency and promoting convection, it is possible to prevent the mixture of sulfur and sodium silicate from being thermally deformed by intensive heating on the burner side. In addition, when the temperature in the chamber rises above the second temperature, each of the first blade and the second blade increases in length by the shape deformation of the second shape memory alloy at the end, further increasing the stirring efficiency and promoting the convection phenomenon more actively. , Similarly, it is possible to prevent thermal deformation of a mixture of sulfur and sodium silicate in Hwangchil tree extract by intensive heating on the burner side.

Furthermore, when the first blade and the second blade rotate, when the value sensed by the phase sensor exceeds the reference value, the electronic control unit dominates the rotation of the first blade and the second blade to increase the height of the surface. It is determined that the rotational speed of the first blade and the second blade can be reduced to be slower than the current operating speed, and the output of the burner is higher than the current output by controlling the burner, that is, the temperature in the chamber is set to the first temperature. It is possible to quickly activate the first shape memory alloy and the second shape memory alloy of the first blade and the second blade by raising the second temperature or more from less than (compensating for the stirring efficiency reduced by the rotation speed).

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features of the present invention. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
