Thus, it is useful for seed coating of smooth and waxy crops such as soybean There will be.
Description
The present invention relates to a method of coating a seed having a wax layer on its surface and a coated seed prepared by the method.
The seed coat is composed of cellulose and hemicellulose, and is coated with a wax material to make it smooth and glossy. The luster of the seed coat is related to the unsaturated fatty acid contained in the seed coat (the relationship between the physicochemical properties and luster of the soybean seed coat, Kim, Sun-Rim et al., Korean Society of Crop Science, v.50 suppl.1, 2005, p123-131) Of the crude lipid content of 18.3%, 1.53% is contained in the seed coat. Thus, the coating of bean seeds is difficult to coat unlike seeds such as rice seed.
Conventional method of disinfecting soybean seeds and preventing bird damage is to sterilize 1 kg of seeds with 4-5 kg of seed sterilizing agent wettable powder No. 1 (benzate tea) or wettable powder No. 2 (Homi) in seeds. However, soybeans are damaged by birds such as pigeons and magpies for a week after their emergence (between 10 and 14 days after sowing). However, since the binding state between the wax layer of the soybean seed coat and the avian influenza is insufficient, it is easily separated from the soil and its effect is lowered. Thus, a method for overcoming this problem is needed.
A variety of granular objects have been developed to protect the bean envelope in various ways to discourage access to the algae and to prevent algae from identifying them as seeds. Korean Patent Registration No. 10-0426809 discloses an active carbon, gypsum, calcium carbonate, slaked lime, talcum, zeolite, vermiculite, bentonite, kaolin, clay, , Diatomaceous earth and peatmoss are said to be effective substances when mixed with two or more substances in the granule.
However, in case of soybeans, it takes a long time before germination due to the characteristics of the soybeans, until the leaves become 3 to 4 leaves or more after germination, and when the soil is over-humidified or dried, And there is a problem that germination does not occur at all or corruption because it is not destroyed.
In addition, since the soybean seeds coated with the above-described conventional seeds have a thin coating thickness of seeds, it is difficult to protect seeds from various algae when they are sprayed on the grass or field, and when the seeding time and the time of germination due to bean coating are not met In addition to rotting and seeds lose their vitality during germination, they are susceptible to damage from birds and rats, and even if germinated, the beans grow too thick and fall down, resulting in poor results, which requires improvement.
Accordingly, the present inventors have developed a coating method of soybean seeds which can prevent the access of algae while maintaining the soybean seed coating liquid for a certain period of time in the course of changing from seed to plant, thereby improving the seeding rate.
Korean Patent Laid-Open Publication No. 2015-0116081 discloses a seed coating composition for bean and green grass seedlings containing perlite. However, the coating method of seeds having a wax layer on the surface of the present invention and the coating seeds prepared by the above- There is no description.
The present invention has been made in view of the above-mentioned needs. The present inventors have developed a method for coating soybean seeds using an avian repellent agent containing a surfactant component as an intermediate material and mixing iron and calcined gypsum. The present invention has been accomplished by confirming an improved catching rate as well as a bird catching effect of 98% or more in a house packing test of soybean seeds coated with the seeds.
In order to solve the above-described problems, the present invention provides a method for producing a wax-coated seed, comprising the steps of: removing foreign substances adhering to the outer surface of seed having a wax layer on the surface; Coating the seed surface with the foreign material removed seed by mixing an intermediate material containing a surfactant component; Mixing iron seeds with seeds on which the coating layer is formed; Mixing the calcined seeds with the iron-mixed seeds; And drying the seeds mixed with the calcined gypsum in a silk screen.
In addition, the present invention provides a coated seed produced by the above production method.
The bean iron coating method of the present invention solves the problems of the conventional bean coating method by grasping the characteristics of the bean seed coat including the smooth form and the wax layer. It not only improves the coating efficiency but also prevents the bird damage It can be expected to improve the natalization rate and reduce labor force. In addition, the weight of the seeds is heavy due to the load of the plaster and the iron itself, so that the seeds are submerged on the surface of the ground, thereby preventing the seeds from being moved by winds or rainwater or other external causes. It promotes the absorption of inorganic nutrients (nitrogen, potassium, etc.) by increasing the oxidizing power. When applied with iron powder, it minimizes the physiological disorder caused by toxic substances such as heavy metals, hydrogen fluoride, and sulfide, So that it can be usefully used for seed coating of a smooth and wax-like crop such as soybeans.
FIG. 1 is a photograph of the result of an empirical test in a packaging house of soybean seeds coated with various soybean iron coating methods.
Fig. 2 is a photograph showing a method for coating iron iron powder and a sowing process of the present invention.
Fig. 3 is a photograph showing the result of sowing of iron-coated (a) or uncoated (b) soybean seeds.
In order to achieve the object of the present invention,
Removing foreign substances adhering to the outer surface of the seed having the wax layer on the surface thereof;
Coating the seed surface with the foreign material removed seed by mixing an intermediate material containing a surfactant component;
Mixing iron seeds with seeds on which the coating layer is formed;
Mixing the calcined seeds with the iron-mixed seeds; And
And drying the seeds mixed with the calcined gypsum in a shade.
In the method for producing a coated seed according to the present invention, the seed having a wax layer on its surface may be selected from the group consisting of soybean, peanut, kidney bean, mung bean, , Corn, mung bean mung bean, crab sprout, reed, red noodle, and corn noodle, preferably soybean seeds, but is not limited thereto, and has a smooth surface having a wax layer Lt; / RTI > seeds.
In the method for producing a coated seed of the present invention, the intermediate material may be, but is not limited to, a dithiocarbamate-based algae avoiding agent containing a surfactant component.
In general, the bond between the wax layer of the soybean seed coat and the iron is disadvantageous in that the binding ability thereof is insufficient so that it is easily separated from the soil and the effect of the iron is inferior. To overcome this problem, a part having affinity with water and a part having affinity with oil (Or an adjuvant) containing a surfactant component of the present invention is used. The dithiocarbamate-based avian repellent used in the present invention is used for the role of the above-mentioned intermediate material rather than alleviating algae damages, The surfactant component in the repellent agent has an effect of enhancing the bonding between the wax layer of the soya seed coat and the iron powder. The role of the surfactant is to increase the binding force with the iron powder by forming a film with the wax layer on the surface of the seed coat. Thus, the iron powder is not easily separated from the soybean seeds, thereby improving the soybean seeding rate and maximizing the avian escape effect.
In the method for producing a coated seed according to an embodiment of the present invention, the intermediate material may be mixed with 10 to 20% by weight, preferably 15% by weight, of the seed weight used in the coating, It does not.
In addition, in the method for producing a coated seed of the present invention, the iron powder plays a role of protecting the seed from algae due to a specific odor generated during oxidation. That is, the effect of algae avoidance can be seen due to the iron component used in the coating rather than the algae removing agent used as an intermediate material. Therefore, in the method for producing coated seeds of the present invention, the adhesion and the sustainability of the coated iron powder have a great influence on the avian avoidance effect and the seeding rate or the germination rate.
In the method for producing a coated seed according to an embodiment of the present invention, the iron powder may be mixed at 35 to 45% by weight, preferably 40% by weight, of the seed weight used in the coating, It does not.
In addition, in the method for producing a coated seed of the present invention, the reason why the calcite is further mixed after the iron powder mixing step is to prevent the coating portion from falling off after the iron powder coating treatment, To prevent the iron from being separated from the seed coat, and to increase the germination rate of the seed by the function of water absorption and soil pH control.
In the method for producing a coated seed according to an embodiment of the present invention, the calcined gypsum can be mixed in an amount of 5 to 15% by weight, preferably 10% by weight, based on the weight of iron, but is not limited thereto.
The method for producing a coated seed according to one embodiment of the present invention is, specifically,
Removing foreign matters adhering to the outer surface of the soybean seed; Coating the soybean seed surface by mixing the soybean seed with the alginate removing agent containing the dithiocarbamate surfactant component containing the surfactant component at 10 to 20% by weight of the soybean seed weight; Mixing the iron seeds of the soybean seed with the algae repellent coating layer in an amount of 35 to 45% by weight of the soybean seed weight; Mixing the fermented soybean seeds with the iron powder in an amount of 5 to 15% by weight of the iron powder; And drying the soybean seeds mixed with the calcined gypsum in a shade. More specifically,
Removing foreign matters adhering to the outer surface of the soybean seed; Coating a soybean seed surface with a dithiocarbamate-based repellent agent containing a surfactant component at 15 wt% of the soybean seed weight; Mixing the soybean seed with the algae repellent coating layer in an amount of 40% by weight of the soybean seed weight; Mixing the fermented soybean seeds with the iron powder at 10 wt% of iron weight; And drying the soybean seeds mixed with the calcined gypsum in a shade, but the present invention is not limited thereto.
In order to accomplish still another object of the present invention, there is provided a coated seed produced by the method for producing a coated seed of the present invention.
The coated seed of the present invention has an effect of reducing the damage caused by various algae in the field because the iron ingredient is uniformly coated on the surface of the seed without deteriorating the seed surface due to the surfactant component. It has the effect of promoting the growth of crops by minimizing the physiological disturbance caused by toxic substances such as hydrogen fluoride and sulfide, and the seeds are submerged on the ground surface by the load of the cobble and iron powder used in the coating, (Nitrogen, carly, etc.) by increasing the oxidizing power of soybean seed roots by the petrolatum, and it is possible to improve the nurturing rate through prevention of algae damage, We can expect a reduction.
Hereinafter, the present invention will be described in detail with reference to examples. The following examples are illustrative of the present invention, but the present invention is not limited to the following examples.
Experimental material
Carbymethylcellulose (CMC, NurimCam, Korea), electrodeposition agent (Dongbang Hanon, Korea), SR- 5000 (Gyeonggi-do Icheon self-assembly), iron (iron and steel ceramics, Korea), and cedarwood (iron and steel ceramics). The bean seeds used in the coating were Uram beans.
Manufacturing example 1: Soybean coating seed production
(1) Removal of impurities on the outer surface of bean seeds.
(2) The soybean seeds from which the foreign substances were removed were mixed with a dithiocarbamate-based repellent agent containing a surfactant component in an amount of 15% by weight of the soybean seed weight to coat the soybean seed surface.
(3) The soybean seeds in which the coating layer of avian influenza was formed were mixed with 40% by weight of the weight of the soybean seeds.
(4) Soybean seeds mixed with iron were mixed with 10 wt% of iron powder and dried in a shade to prepare bean-coated seeds.
Experimental Method
Six test zones; 3) carboxymethylated cellulose (CMC) 3% + iron treatment treatment 4) carboxymethylated cellulose 1% + iron treatment treatment 5) electrodeposit + iron treatment treatment 6) SR -5000 (granular seed coating agent) + iron powder treatment. Twenty seedlings were sown in each test, and the packaging adaptability, germination period and aspect (iron peel application state) were examined.
The composition of each test is shown in Table 1 below.
(10% of iron weight)
Example 1. Packaged house demonstration test
As shown in Table 2, the highest germination was observed in the treatments coated with avian repellent, iron powder and calcined gypsum. In the untreated control without iron coating, the highest number of soybean germination was observed until the 7th day of the test, but the number of germination seeds did not increase any more after the 8th day of the test. The germination numbers of carboxymethylated cellulose (CMC) Ⅰ and CMC Ⅱ groups were higher than that of untreated group, but the number of germination was less than that of treated group with avian catching agent and iron and. It was confirmed that the deposition rate of iron peel by CMC was lower than that of avian flounder, and the number of germination was small around 10 days after the test. In addition, there was no germination of soybean seeds in the electrodeposited treatment area, and only two germination individuals were observed after the 11th day of the test in SR-5000 treatment.
From the germination counts, 80% germination days and germination results, it was found that the treatments coated with avian repellent, iron powder and calcined gypsum showed the best effect. In addition, in general, in contrast to the case where germination is not performed after 5 days of soybean seed, the seeds coated with avifauger agent and iron powder and calcined gum can be germinated even after 15 to 20 days after protecting the root muscle by maintaining moisture Data not attached).
The components of the electrodeposit used in the present invention were 10% of polyoxyethylene alkyl aryl ether, 20% of sodium lignosulfonate, antifreeze agent and solvent of 70% According to the evaluation report of the Korea Institute of Agrobiological Sciences, it was confirmed that the ginseng was not germinated due to moisture contaminants among the above components, which interfered with moisture access and absorption of the seeds. That is, it is considered to be unsuitable for use as an intermediate material for iron iron coating.
Example 2. Avoiding birds in the field
After the test in the packing house, the test was carried out using iron coated untreated control, carboxymethylated cellulose (CMC) 3% + iron powder treatment (CMC I), carboxymethylated cellulose 1% + iron powder treatment (CMC II) Seeds were planted in the field to verify the effect of avoiding actual birds. As a result, as shown in Table 6, higher avian escape effect was observed in the test group in which seeds coated with avian repellent agent and iron and calcitonin were planted compared to the control group planted with untreated soybean seeds (FIG. 3). In the field test, the treatments coated with avian repellent and iron and plaster were applied to the cotyledon for a long period of time. It was found that the treatments coated with avifauger and iron and plaster were more effective than the CMC I and CMC II treatments in the field.
Example 3. Avoidance of algae against prior art
For the treatment group in which beans were coated with the coating material consisting of the iron powder and the calcine as described in the prior Japanese Laid-Open Patent Application No. 2010-0054704, and the treatment group in which the soybean-removing agent and the iron powder and the calcined powder of the present invention were coated on the soybean, Similar to 2, the avian avoidance effect was compared in the field (Table 7). As a result, it was found that the soybean seeds coated with iron and cadmium were significantly lower in avian avoidance effect than the group treated with the avian repellent agent of the present invention and iron and fumaric acid.
(Iron and plaster coating)
(Avian repellent and iron and plaster coating)
Example 4. Comparison of avoidance effects of algae according to the content of each component of the coating material of the present invention
The inventors of the present invention have sought to find an optimum combination of the antifouling effect according to the content of each component of the coating material of the present invention. Soybean-coated seeds were prepared in the same manner as in Preparation Example 1, using the respective components of the content ratios shown in Table 8 below.
(Production Example 1)
Similar to Example 2 above, soybean-coated seeds prepared as in Table 8 above were compared to avoidance of algae in the field (Table 9). As a result, it was found that the bird avoidance effect of the soybean seed coated with the composition ratio of Production Example 1 of the present invention was remarkably higher than that of the soybean seeds of Comparative Examples 1 to 4 coated with different composition ratios.
