Description

Application method of rare earth fertilizer and rare earth compound fertilizer {RExOy-FERTILIZER AND IT'S APPLYING METHOD}

The present invention is to present a new rare earth complex fertilizer as a new fertilizer component in addition to the conventional fertilizer components that have been used and used conventionally, and to propose an optimal application method.

Fertilizers are used to promote plant growth and harvest by artificially supplying ingredients that are easily deficient from the soil. Various types of fertilizers are used according to soil and crops.

Typical fertilizer is a compound fertilizer made by mixing and mixing three components of nitrogen (N), phosphoric acid (P), and calories (K) in excess of 20%, and it is indispensable for the healthy growth of plants. Microelement complex fertilizer manufactured by mixing boron, zinc, manganese, molybdenum, copper, iron, etc. is used. Various types of fertilizers are used depending on the cultivation environment such as fertilizer, compost using plant or animal extract.

In particular, unlike macrourea fertilizers by nitrogen, phosphorus, and calories, trace elements have a significant effect on plant growth even in very small amounts, and in very small amounts, severe growth disorders occur and such symptoms do not appear immediately and are very slowly. Due to its characteristics, it is necessary to pay close attention to crop cultivation, and to study the pre-supply plan or follow-up measures of ingredients that are likely to be deficient, and to study other trace elements that are easily deficient in plants.

As a result, agricultural research on rare earths present as trace elements in the earth's crust is under way, and the presence and quantity of rare earth elements affect living organisms, and in fact, they promote growth and development when rare earths are applied to crops and animals. It has been found to increase the physiological activity and the effect of yield and quality improvement.

Rare earth is a trace element containing about 0.016% in the earth's crust as a metal element, and radium (La) -based elements (La, Ce, Pr, Nd, Pm, Eu, Gd, Tb, Dy, Er, Tm) in the periodic table of chemical elements It is a concept that refers to the mineral containing 17 elements together with Sc and Y, which are included in the general rare earth minerals such as, Tb, Lu) and each element because the elements are almost similar in physical and chemical properties. Although it is complicated to separate by, there are special differences between each element, so each can be separated into a single element.

In addition, rare earth metal has soft texture and surface gloss, has excellent stretchability, and is used as a material for ignition and etc. as a magnetic and superlative conductor.In recent years, rare earth metals are widely used in steel sintering agents, colored alloys, and electronic materials. The agricultural use is only partially used as a fertilizer for food crops and as an additive in the livestock field, and there is no systematic research and use of it in Korea.

The present invention provides a rare earth compound fertilizer that can be easily applied to the general farmers in accordance with the domestic soil environment and cultivation crop environment, and to achieve the purpose of promoting the growth and harvest of crops by using rare earth for agriculture, and trace urea fertilizer The purpose of this study was to present a new method of using complex fertilizers.

To this end, the present invention newly proposes a method of applying a rare earth complex fertilizer containing a rare earth optimum content of the fertilizer containing rare earth in the microelement compound fertilizer used for foliar fertilization and a dilution ratio in a range that does not harm crops.

Hereinafter, the configuration and effect of the present invention will be described in detail through specific examples.

The rare earth composite fertilizer application method according to the present invention is La, Ce, Pr, Nd, Pm, Eu, Gd, Tb, Dy, Er, Tm, Tb, Lu, Sc, Y complex rare earth consisting of 17 metal elements (RExOy ) Dilute the complex rare earth powder by grinding it into fine powder in water, and adjust the titration concentration to 300-500ppm under the condition of PH7 or less, and this is 2-3 times during the germination, nutrient growth stage, and early stage of reproductive growth. It's a turn to try.

The composite rare earth according to the present invention can be used alone or in combination with a ready-made fertilizer and pesticide.

Ready-made fertilizers can be applied to non-alkaline fertilizers, for example, urea fertilizers, nitrogen fertilizers and Class 4 trace urea fertilizers, and are compatible with pesticides of PH7 and below.

According to the experiment, when alkaline soil or dilution water of PH7 or more is encountered, the rare earth hardens and there is no application effect.

Therefore, when used as foliar cost, water of more than PH7 should not be used as dilution water, and 30-50 ml of hydrochloric acid may be mixed with water to satisfy such conditions.

Nitrogen fertilizers or urea fertilizers and trace urea complex fertilizers are mainly used for mixing.

Nitrogen fertilizers and urea fertilizers are used for surface fertilization and mixed with 15 kg of urea or nitrogen fertilizer for 60 g of mixed rare earth, and the mixing ratio of mixed rare earth is about 0.4%, Allow approximately 180g of usage.

The application of mixed pesticides or fertilizers to the complex rare earth is to avoid duplication of labor due to fertilization, and it can be applied as a first aid measure when supplementing or supplementing the surface or in case of nutrition, in which case the compound rare earth is applied alone. In the case of nutrient cultivation, it can be easily mixed with other nutrient solutions.

The microelement compound fertilizer is used for foliar fertilization of complex rare earths, and the application of microelement compound fertilizer and complex rare earth at the same time saves labor for each application, and the rare earth component activates plants to increase the absorption rate of trace elements. To increase the effect.

Therefore, if you do not consider the labor for the trial work, you can use the complex rare earth alone.In that case, mix 60 g of the complex rare earth with respect to 40-60ℓ of water and dilute it to a concentration of approximately 300-500ppm, and timely to the back of the leaf of the crop. Give enough to make.

The timing and frequency of lateral fertilization can be obtained by two or three times during the early germination, nutrient growth stage, and early stage of reproductive growth, as evidenced by the accumulated knowledge of plant cultivation methods. Day afternoons are best, and when applied on rainy or sunny mornings, they are ineffective or cause harm.

On the other hand, unlike the first compound fertilizer, the trace element compound fertilizer is manufactured by a precise manufacturing process, so that the mixed rare earth can be precisely weighed and mixed, and the trace element compound fertilizer and the compound rare earth can be precisely weighed and mixed during the manufacturing process. In addition, since it is applied mainly on foliar fertilization, there is an advantage of achieving precision of application.

In addition, the mixing of trace urea complex fertilizer and rare earth has the advantage of better application effect than rare earth alone, because it promotes the growth rate of crops and increases the absorption rate, and general farmers who have experienced the application of conventional trace urea complex fertilizer There is an advantage that can be easily applied even if you do not learn a separate function.

To this end, the present invention also proposes a rare earth composite fertilizer having a rare earth mixed with an appropriate ratio.

The trace element is a minimum amount specified in the fertilizer process standards of the Fertilizer Management Act, boron 0.05%, copper 0.05%, iron 0.1%, manganese 0.1%, molybdenum 0.0005%, zinc 0.05% or more as a guarantee component of the crop It is manufactured by adjusting the content ratio in consideration of the type and soil environment, and the compounding ratio can be configured in various ways, and the amount of rare earth mixed is about 10%, which is almost different from the existing method of applying the trace element complex fertilizer. It can be applied in the same way.

For example, dilution with about 67 liters of water with respect to 100 g of rare earth complex fertilizer containing trace elements can match the optimum concentration of the rare earth 500 ppm.

Trace elements are rare earth application effects and trace elements by formulating in a direction roughly corresponding to the recommended application concentrations of boron 100-600ppm, manganese 250-1000ppm, copper 10-500ppm, zinc 100-600ppm, molybdenum 10-50ppm The application effect can be achieved at the same time.

Table 1 shows the specific raw material mixture ratio of the rare earth composite fertilizer according to the present invention as an example.

The acid and water are used to induce the crystallization process of the conventional microelement fertilizer manufacturing process, consisting of raw materials, blending, acid + water reaction, crystallization, grinding, rare earth mixing, packaging process.

The present invention according to the above configuration is described in the application examples applied to each crop for farming pavement in Jeongeup-si rural guidance laboratory and hydroponic cultivation glass greenhouse and Jeongeup-si as follows.

A. Effect of complex rare earth application

Table 2 shows the effects of barley seed germination when the treated and non-treated groups were inoculated with rare earth treatment concentration of 300,400,500,1000ppm for 5 hours.

According to the above table, the germination rate is shown in the order of 400,300,500,1000 and control in the case of barley, and Namac is shown in the order of 300,400,500,1000 and control in order, and it can be seen that the germination rate is increased by 7.1% compared to no treatment. have.

According to this result, the complex rare earth has the effect of promoting the seed germination of the crop, the mechanism of action is present in the homogeneous layer known to induce the expression of GA ₃ to promote seed germination -amylase, It is believed that this is because it promotes the formation of -amylase and improves the respiration rate, germination rate, germination rate of seeds by activating other enzymes, and it is found that the treatment concentration of complex rare earth is the best at 300-400ppm. Can be.

2) Rooting and Root Growth

One important function of roots in plants is the nutrient absorption and the synthesis of cell division elements, which have a direct effect on the vitality of the root system.

The growth promotion effect of root system according to the treatment concentration of rare earth on lettuce is shown in Table 3.

According to the table above, in the root growth of the lettuce crops, 300,500 ppm of rare earth sedimentation treatment plants increased by 20.9% and 17.7%, respectively, in the seedlings. It shows a significant increase of% and 13.0%.

B. Effect of Rare Earth on Rice

1) Effect of rare earth use on rice harvest

For Dongshin rice, Hwashin rice, and Ilmi rice, divided into the first treatment (OT ₁ ), the second treatment (OT ₂ ), and the third treatment (OT ₃ ) 7 days before the first rice transplantation, the second cleavage phase, and the third sowing stage. The first treatment zone treated the complex rare earth concentration at 100,200ppm over the first and second stages, and the second treatment zone treated the first 150ppm, the second 200ppm, and the third 300ppm, and the third treatment zone was the first 200, the second 300. The treatment of the third 400ppm treatment effect and the effect of the concentration was compared with the untreated control, the results are shown in Table 4.

According to the above results, the yield increased in the whole rare earth treatment zone, and it was found that the effect was better in the second and third treatment zones than the treatment zone in which rare earth was applied twice.

Looking at this by packaging, Dongjin (OT-1), Hwashin (OT-2) it can be seen that in the order of the third treatment, the second treatment, the first treatment, the quantity increases compared to the control, Dongjin (OT-1 ) Was 10.7%, 9.7%, and 6.4%, an average of 8.9%, and the average rate of 6.8% was also increased by 8.8%, 7.0%, and 4.6%, respectively. In addition, the average increase of 5.0%.

By treatment, the first treatment showed an increase of 5.3%, the second treatment 7.9%, and the third treatment 7.5%, showing that the second treatment increased more than the third treatment. Therefore, it is believed that this is because it was consistent with conventional preparation without considering the growth trend of the increase of fertilizer absorption, and the necessity of more precise application of rare fertilizer application to rare earth application may be raised. .

2) Effect of Rare Earth Application on Quality

To determine the effect of rare earth application on rice quality, the results of protein analysis are shown in Table 5.

According to the above results, the protein content of the rare earths showed a tendency to increase as a whole, and by the treatment groups, it was found that the increase was greater in the second and third treatments of three treatments than the first treatment treated with the rare earths twice. In particular, it can be seen that the second treatment increased by 17.6% compared to the control.

3) Pesticide residue reduction

As a result of the empirical experiment, the effect of reducing pesticide residues by sample analysis is shown in Table 6.

As can be seen from the above table, it was found that the effect of reducing the residual amount of IBP and Iprobenfos, which are components of the kita entrant, was observed in the grains of rice by the rare earth treatment. It can be seen that in the second and third treatment groups, 32.8% and 36.6% were significantly reduced, respectively.

The rare earth application effects described above were limited to the germination effect of barley seeds, growth effect of lettuce, rice yield, quality improvement and reduction of residual pesticides, but the representative varieties and promising incentives (rice, apple, grape) of Jeongeup region , Pepper, melon, tomato, parsley, and Chinese cabbage) were selected as the packaging shown in Table 7, and the empirical experiment was conducted.

Saturn is a typical silty loam that has good application effect in non-alkaline soil conditions ranging from PH 6.4 to 3.8.

2) Rare earth application effect on crops was different depending on crop, type, soil, variety, and cultivation method. However, in the yield, rare earth three times treatment was higher than second treatment. In general, the higher the concentration, the higher the concentration, the higher the concentration of sugar, vitamin C, and pesticide residue.

3) Rare earth application effect for seed germination, root growth, and rooting promotion was slightly different for each crop, but the effect was obvious, and the application effect was most appropriate at 300-500ppm concentration.

As described above, it can be seen that the yield of the crop is increased, the quality is improved, and the amount of pesticide residue is reduced by the application of the rare earth complex fertilizer according to the present invention.

The present invention promotes the agricultural use of rare earth, which has not been attempted so far in Korea, and has the effect of contributing to the promotion of crop growth and the increase of yield by revealing the optimum application conditions, and mixed with the microelement compound fertilizers that have been used in the past. By presenting a new rare earth complex fertilizer of the composition that has the effect that farmers can easily apply even if they do not acquire a separate application technology.
