Description

Complex farming system

The present invention relates to a complex farming method that performs the cultivation of rice and the growth of shrimp at the same time by putting shrimp in the paddy field for environmentally friendly rice cultivation.

Recently, the opening pressure of the agricultural market, which is rapidly progressing, is bringing great difficulty and crisis consciousness to Korean agriculture, which is not superior to the international competitiveness. To make matters worse, the production-oriented agricultural cultivation method, which has been developed under the premise of using pesticides and administering large amounts of chemical fertilizers, has been recognized as a source of soil and water despite its contributions to Korean society, which has lacked the absolute amount of food. The current situation is that consumers are distrustful of producing unsafe agricultural products. Increasing national income, on the other hand, has led to a transition from a well-being diet to a well-being diet, resulting in a surge in demand for functional and safe produce, despite relatively high prices.

In order to grow agricultural products safely with minimal use of pesticides and chemical fertilizers, attempts have been made to introduce a complex farming method that grows various other organisms such as loach, thunder, carp, crab, duck, crucian carp in rice growing fields. .

However, no reports have yet been made of shrimp into the paddy fields. Especially among shrimps, it is very difficult to grow and sensitive to pollutants. If there is a small amount of pesticides, it will not grow.

Therefore, it is necessary to grow rice that does not affect the taste without the use of pesticides, but also a way to safely grow shrimp such as saengbange.

Therefore, the present invention is to provide a complex farming method that is combined with environmentally friendly rice cultivation of shrimp that can be grown only in the blue and blue environment sensitive to pollutants.

In addition, the present invention is to provide a complex farming method that can contribute to improving the utility of the debate and improvement of farm income.

In the above embodiment, the shrimp may be prawns or savannah.

In the above embodiment, the shrimp may be 10 to 30 kg per 1,000 m 2 of the amount injected into the paddy field.

In the above embodiment, the marrow may be further added before the shrimp is added to the rice paddy.

Another preferred embodiment of the present invention provides rice grown by the above-mentioned complex farming method.

Rice according to the embodiment may be selected from white rice, black rice, germinated brown rice, red rice and green rice.

In another preferred embodiment of the present invention provides a shrimp grown by the complex farming method.

In the above embodiment, the shrimp may have a productive output (RO) of 20.0 to 30.0% range represented by the following Equation 1.

<Equation 1>

In the above embodiment, the shrimp may have a gonad maturity index (GSI) of 0.1 ~ 30.0 represented by the following formula (2).

<Equation 2>

In the above embodiment, the shrimp may be a female shellfish (CL ₅₀ ) to reach 50% maturity of 6.0 ~ 9.0mm.

The present invention can provide a complex farming method capable of simultaneously performing shrimp and environmentally friendly rice cultivation that can be grown only in the blue and blue environment sensitive to pollutants.

In addition, the present invention can provide a complex farming method that can contribute to improving the utility of the debate and improvement of farm income.

In another aspect, the present invention can provide a rice planted environmentally friendly by using a complex farming method of introducing shrimp.

In addition, the present invention can provide a shrimp grown by using an environmentally friendly complex farming method.

Hereinafter, the present invention will be described in more detail.

The present invention is to provide a complex farming method to perform the cultivation of rice and shrimp growth at the same time by putting shrimp in the rice paddy.

Shrimp that can be used in the complex farming method of the present invention is preferably shrimp or savannah.

Shrimp ( Palaemon paucidens) is about 6cm long, lived in a river, lake, or brackish water mixed with fresh water and seawater, and in the end of April to mid-August, you can see the animals that have eggs. It is used as a natural feed for fish and as a bait for fishing.

Shrimp ( Neocaridina denticulata denticulata., Toha) is a 2 ~ 3cm long freshwater shrimp known to live in uncontaminated clean water such as valleys, valleys, and ponds throughout Korea. It is a raw material for tohatsu flavored with ginger and red pepper powder, and is consumed at a very high price.

These shrimps and shrimps are not easy to grow because they are sensitive to dissolved oxygen and pesticides. Shrimp and shrimp are also short-lived (within 1 year) and require adequate shade and attachment, and from an ecological standpoint they can have an optimal symbiosis with rice grown freshly from harvesting to harvesting. Shrimp and Shrimp are used to feed not only freshwater plankton and attached diatoms such as diatom and rotifer from freshwater, but also pirate organisms such as rice germ and microbes, so it is expected to help rice growth without nutrient contention with rice. As such, paddy fields can provide a very good shrimp farming environment without additional feeding efforts. On the other hand, it is also necessary to feed the pirates as described above for the growth of shrimp, so no additional feed is required, but if the concern is a decrease in water temperature, lack of sunlight, it is preferable to supply the chlorella required for the initial growth of shrimp.

In the complex farming method of the present invention, the shrimp is added to the rice paddies at the beginning of the rice transplanting, preferably 10 to 30 kg per 1,000 m 2 of rice paddies, and the depth of discussion is preferably 10 to 30 cm. This takes into account the depth required for shrimp growth rather than rice growth. On the other hand, it is appropriate to add the broodstock (mother shrimp) or hatched larvae as shrimp added at this time.

In the early rice field, the rice paddy conditions are stressed, so it is necessary to provide a separate shade, and under the conditions of rising summer temperature, deep water depth is required, but some areas are rather than always kept deep. Digging deeper than 30cm deeper than the bottom of the paddy field, installing a structure with a rod on it, and then covering it with a shading net is more effective for shrimp growth.

Paddy structures that provide such shades and depths of view are more advantageous in forming and working on rice paddies, but in the case of wider rice fields, it may be more efficient to create the rice paddies in the longitudinal direction.

In addition, it is essential to install a guard net of about 1m high to prevent shrimp from popping out of the paddy field and to prevent birds such as storks from feeding the shrimp.

And it is preferable to have a drainage channel of sufficient depth for efficient harvesting of shrimp, it is preferable to have a drainage channel of 30 ~ 40cm × 30 ~ 40cm in depth on the ground surface.

Shrimp harvest should be harvested as late as possible, taking into account the time required for paddy hardening required for the combine operation on the basis of 45-55 days of rice harvest after harvesting.

Shrimp does not move to water at a high flow rate due to ecological habits, but rather is attached to an object. Therefore, it is preferable to induce the shrimp to move arbitrarily along the drained water by gradually lowering the water level. After the shrimp is harvested once, most of the shrimp that is not harvested in the first harvest is harvested after blocking the rice paddies and watering the groundwater.

For harvested shrimp, freshwater prawns such as prawns or savannah, in the composite farming is that the reproductive output (RO) represented by the following formula 1 is in the range of 20.0 to 30.0%.

<Equation 1>

In addition, in the case of freshwater prawns such as prawns or saengyi shrimp, the gonad maturity index (GSI) represented by the following formula 2 is preferably 0.1-30.0 in the complex farming.

<Equation 2>

In addition, in the case of freshwater prawns such as prawns or savannah, the harvested shrimp is preferably in the complex farming, where the female shellfish (CL ₅₀ ), which reaches 50% maturity, is 6.0 to 9.0 mm.

On the other hand, overwintering shrimp is the most economical way to establish a system for supplying shrimp for self-stocking. To this end, secure a reservoir of 15㎡ (3m × 5m × 2m) depth per 10a (1,000㎡) of cultivated area, transfer some of the shrimp harvested in the fall to the secured reservoir, and then place the plastic house in the upper space of the reservoir. It is preferable to install. During the wintering period, the activity of the shrimp is extremely deteriorated, so no additional feed is required. If the depth is 2m underground, the water temperature of about 4 ~ 5 ℃, which is the wintering temperature of the shrimp's natural ecosystem, is maintained. .

As described above, rice grown using the complex farming method of the present invention in which shrimp is added to rice paddies may include white rice, black rice, germinated brown rice, red rice, green rice, and the like. In order to secure, it is desirable to select varieties that form supertypes and have a short intercalar elongation.

To disinfect seeds of selected varieties first, disinfection of seeds using warm water immersion methods or environmentally friendly materials suitable for organic growing conditions is required.

The soil for planting is not particularly limited and it is sufficient to use soil for well-known organic cultivation.

Since seeding requires seedlings grown for 40 to 45 days or longer as the initial depth of transplanting is required, sowing should be carried out in consideration of the scheduled transplantation date.

On the other hand, the weed generation in the combined farming method of the present invention is judged to have a beneficial effect on the shrimp habitat for shrimp, but the various weeds present in the paddy field as the shrimp must be recovered along with the drainage during the harvesting of shrimp Since we are creating a very unfavorable condition for shrimp harvesting, weed control is preferably carried out for harvesting, not the growth of shrimp. Of these environmentally friendly weed control methods, the use of ducks should be avoided because shrimp can be used as food for ducks. Weed control using rice bran damages shrimp due to poor environment such as eutrophication of rice paddies and oxygen depletion after rice bran administration. Is concerned. However, when rice bran was administered to a deep paddy field, it was observed that the number of grains of rice increased, so it is also preferable to use rice bran farming in parallel. On the other hand, worms are most desirable considering that they have no predatory relationship with shrimp.

In general, irrigation is not possible because general agriculture water supplied by agricultural infrastructure uses water from reservoirs or lakes, and there is a high risk of a large number of pirates feeding shrimps such as various fish. In addition, in order to secure as many shrimp growth periods as possible, shrimp must be harvested immediately before harvesting rice, and thus, constant freshwater must be carried out throughout the entire rice growing season. Therefore, in the complex farming method of the present invention, constant supply of groundwater using a well is preferable.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the scope of the present invention is not limited to the following Examples.

6. Shrimp Porcine, Development and Observation of Larvae

(1) Characteristic and sampling method of experimental shrimp

① Shrimp

The Shrimp ( Palaemon paucidens) used in this experiment is a species of genus Shrimp belonging to the genus Shrimp family, collected as shrimp nets (mesh size: 0.5 × 0.5 cm) from Pyeongji Reservoir in Sanji-myeon, Mungyeong-si, Gyeongbuk, Korea In June 30, 2005, in the test area of Chungnam Agricultural Research and Development Institute, and the field of Songak-myeon, Asan-si, July 1, 2005, the second year of the experiment, July 12, August 23, and August 30, 2006, Chungnam Agricultural Research and Development Institute It was stocked at the precision test package test zone and the test package at Songak-myeon farm in Asan-si.

② new man

Sage ( Caridina denticulata denticulata ) is a genus of the genus Sage and the genus Saengsip. Collected with shrimp nets (mesh size: 0.5 × 0.5 cm) in a valley located in Pyeongji-ri, Mt. In the second year of the experiment, young animals were stocked on July 9, 2006 with the cooperation of the relevant research institutes.

<Gathering of shrimp specimens>

Small shrimp collection nets and nets were collected for 22 days from October 7, 2005 to October 29, the same year. The net size of the net was 0.1 cm, and the collected sample was taken to a laboratory after collection, and the whole sample was fixed with 10% of formalin, fixed with 70% alcohol after 24 hours of subsampling, and used for analysis.

(2) Analysis method of shrimp sample

Samples were randomized and the carapace length (CL) was measured using an image analysis system (Olympus SZX12, Image analysis software; Image-Pro Plus Version 4.1) to determine the shortest distance from the base of the eye to the edge of the medial line of the shell. Measured to mm (FIG. 1). The distribution of body frequency was indicated by the length of each body at intervals of 0.5 mm crustacean, and the weight was measured up to 0.0001 g using an electronic scale (Sartorius, CP64). Sex classification was performed under anatomical microscopy (Olympus, SD30). Male and female were determined by the presence or absence of a spinal cord of the second leg of the leg. The monthly sex ratio was expressed as the ratio of the number of female individuals to the number of female individuals.

(3) How to measure shrimp poaching, development and larval growth rate

end. Egg size, egg volume, and reproductive output of shrimp

The eggs were counted after all the females were collected. The measurement of the number of eggs was carried out by separating the eggs attached to the welfare of the females with tweezers and dividing them into two stages, and counting them directly by using an anatomical microscope. The number of eggs was defined as the number of eggs in the welfare of a female. The separated eggs were divided into two stages according to the following developmental stages artificially set under an anatomical microscope. Stage A can not see the eye pigments of the larvae in the egg, stage B was divided into stages to see the eye pigments of the larvae in the egg. In order to calculate the volume of eggs, five eggs per individual were randomly selected from the counted eggs, and the long and short diameters of the eggs were measured. The eggs were treated as ellipses and the volume was calculated according to the following general formula:

<Equation 4>

(Wherein r ₁ = Radius of long diameter, r ₂ = Radius of short diameter)

Estimation of the number of eggs and crustaceans and the estimation of reproductive output (RO) were performed in females with no eyes with low egg loss. The dry weight of the females and the dry weight of the eggs were measured in an electronic balance after drying in a dry oven for 48 hours at 80 ℃. Reproductive output (RO) was measured by dry weight, and was determined by Clarke et al. It was estimated using the equation (1991).

<Equation 1>

I. Gonad maturity index (GSI)

The spawning period was achieved by a change in the gonadosomatic index (GSI) of inbred females. The gonad maturity index (GSI) was dried for 48 hours in a gonad 80 ℃ dry oven separated into females, each weight was measured by an electronic balance to the 0.0001 g by the following formula (Equation 2).

<Equation 2>

The spawning frequency was divided into 5 stages of the female gonads to observe the change in the developmental stage and the gonad stage or gonad maturity index according to the egg stage to determine whether they spawn once or multiple spawning during a given spawning season.

The developmental stages of the gonads were divided into the following five stages (Ⅰ through Ⅴ).

Stage Ⅰ: Immature, thin and transparent gonads

Stage II: Gonad development, bright green and opaque gonads for about 4 minutes 1

Ⅲ stage: incomplete, half of gonads present on head and chest

Ⅳ stage: completion, about 3 minutes at 4 minutes of head

Ⅴ stage: full maturation, full of gonads full of gonads

All. Military maturity of shrimp

Size at sexual maturity was based on the number of females in the gonads maturity or inbred. Group maturity (P) was estimated by the logistic equation (Campbell, 1985) (Equation 3) below by calculating the proportion of mature females between each body class.

<Equation 3>

Where P is the maturity ratio, a and b are nonzero rational numbers as variables, and CL is crustacean.

Variable estimation in the above equation was estimated by nonlinear regression in SYSTAT version 10.0. The length at which sexual maturation occurs, ie the crustacean (CL ₅₀ ) at which 50% of female subjects reach maturity, was calculated as the ratio between a and b (CL ₅₀ =-| a / b |).

la. Root number, egg volume, and reproductive output of a new egg (RO)

Egg stages of inbred females were divided into two stages. Stage I was divided into eyesless eggs and stage II into eyesless eggs. Eggs attached to the well-being of the nested females were carefully separated with tweezers to measure the number of eggs. Estimation of reproductive crust softness and reproductive output (RO) were performed in females with no eyes with low egg loss. The dry weights of the females and eggs are shown by weighing each dry weight to 0.0001 g on an electronic balance. Reproductive yield was determined by measuring dry weight, below Clarke et al. It was estimated using the equation (1991). The egg volume (EV) was estimated using the formula (Equation 4) for the volume of the ellipse using an image analysis system.

<Equation 1>

<Equation 4>

(R ₁ = radius of long diameter, r ₂ = radius of short diameter)

hemp. Goat maturity index (GSI)

The ovarian stage of each female was determined using a microscope capable of measuring up to micrometers. The ovary was separated into three random stages according to the visible criteria step by step.

Stage Ⅰ: Immature, thin, bright orange gonads

          1 minute in the whole, oocyte <0.3 mm in diameter

Stage II: Gonad development, orange gonads throughout the chest

          2 to 3 minutes, 0.3 to 0.5 mm in diameter oocyte

Ⅲ stage: full maturation, dark orange gonads

          Present in most, oocytes> 0.5 mm in diameter

The gonad dry weight was expressed by measuring each dry weight up to 0.0001 g with an electronic balance. The GSI formula consisted of the following formula (Equation 2).

<Equation 2>

bar. New Mature Military

The percentage of fully matured females was based on the number of females in gestational age or the number of females whose ovary maturation had passed stage I and the number of females that were in ovulation plus ovarian maturation stages of each size type. Group maturity (P), the proportion of fully mature females in the crustacean (CL), was estimated using logistic equation graphs.

<Equation 3>

Where P is the maturity ratio, a and b are nonzero rational parameters, and CL is crustacean. Variable estimation in the above equation was estimated by nonlinear regression in SYSTAT version 9.0. The length at which sexual maturation occurs, ie the crustacean (CL ₅₀ ) at which 50% of female subjects reach maturity, was calculated as the ratio between a and b (CL ₅₀ =-| a / b |).

7. Shrimp Growth in Package

During the second year, the growth of shrimp samples collected for 3 months at 1 month intervals in each test zone was evaluated.

8. Overwintering Experiment Method of Shrimp

In order to examine the wintering method of shrimp and toha, the shrimps collected from precision test packaging and farm demonstration test packaging are kept in water temperature 15 ℃ ~ 18 ℃ in winter breeding tank and plastic tank in general building during winter season. Feeding was done once a day to prevent the breeding for about a month and confirmed the number of deaths.

Evaluation and measurement results of each item for the above examples are as follows.

1. Changes in Rice Growth and Development by Combined Farming

end. Changes in Rice Growth in Early Yiang with Depth and Rice Bran Treatment Before Shrimp

-In the present invention, the organic farming method for raising shrimp was a prerequisite, and rice bran farming was introduced for weed control in organic rice fields. The rice bran farming method has a great influence on the initial growth of the rice transplants, so it is necessary to evaluate the growth status of the rice before shrimp is introduced. In particular, shrimp must be secured to a depth of up to 30 cm, secure a shade net that provides enough shade for the shrimp to stay, and to secure powder. It was a decisive factor in the timing of input.

-The results of evaluating the initial rice transplanting length according to the rice bran farming method (rice bran treatment) are shown in FIG. The treatment resulted in an increase of about 8% compared to the control (49.2 cm), and even at high depths, rice bran treatment (52.5 cm) increased the control height by about 8%. As it is advantageous to secure high growth for a short time, the introduction of the rice bran farming method will help Nampyeong rice to secure shrimp growth period in paddy fields rather than Sachuchu.

-The results of evaluating the initial number of rice transplants according to rice bran treatment are shown in FIG. In the case of Nampyeong, there was no effect of rice bran treatment at low water depth, and in the case of high water, rice flour treatment (16.8) showed two increase in the number of sesame seeds compared to the control (14.7). Considering the ecological characteristics of the shade-loving shrimps, early harvesting of large amounts of water favors the growth of shrimps.

-The results of evaluating the initial chlorophyll content in rice transplantation are as shown in FIG. 4, and in case of Saechu Cheong, there was no effect of rice bran treatment at low water depth. In the case of Nampyeong, rice bran treatment effect was not shown in high water depth, but rice bran treatment (38.2) showed chlorophyll content higher than control (35.8) in low water depth.

I. Changes in Later Rice Growth after Combined Farming with Shrimp

1) First year test result

-Combined farming with shrimp imposes specific conditions, such as always fresh water and maintenance of water depths higher than practice. Therefore, in order to investigate how the pavement condition affects rice, shrimp was added to the paddy field, and the late rice growth was evaluated (August 24).

-The change in the height of the late rice growth after the addition of shrimp is shown in FIG. In case of Sachuchu, there was a difference in height according to the depth. The height of the high water was lower than that of the low water. The second chapter appeared. On the other hand, in the case of Nampyeong, there was no difference according to the depth, and in view of the above results, it was judged that Nampyeong had a lower responsiveness to the depth than the Cheonju.

-After the shrimp injection, the chlorophyll content in the late growth was examined with SPAD as shown in FIG. In the case of the low water depth of Sachuchu, the SPAD values of 1 kg of shrimp and 1 kg of rice bran + 1 kg of shrimp were 31.7 and 30.7, respectively, which were 6% and 3% higher than those of the control (29.8), respectively. There was no difference. In the case of Nampyeong, the 1kg of shrimp and the 2kg of shrimp weighed 32.6 and 33.1, respectively, about 6% and 10% higher than the control (30.2). In view of the above, the input of shrimp was somewhat effective in increasing the chlorophyll content of rice, but considering the fact that it was not proportional to the input of shrimp, further investigation of its mechanism and reproducibility would be needed. It is feed.

-Microscopic analysis by shrimp treatment showed no significant difference between untreated and shrimp treatments.

-As a result of evaluating the taste of the rice harvested in the second year experiment, it was judged that the shrimp stock does not affect the taste because the difference between treatments was not recognized similar to the first year (Fig. 8).

3. Changes in Soil Physicochemical Properties

-In the first year, the soil physicochemical properties by shrimp treatment showed similar results for pH, organic matter (OM), effective phosphoric acid (P ₂ O ₅ ), cation, and base substitution capacity (CEC). EC) and effective silica (SiO ₂ ) were somewhat different between treatments (Table 10).

-In the second year of precision test packaging (Table 11), organic matter content and CEC were slightly increased, while phosphoric acid and silicic acid content were decreased by shrimp input. However, since there was no response proportional to the input of shrimp, it was judged that more accurate and repeated analysis should be performed to evaluate the soil chemistry by the effect of shrimp.

4. Shrimp Survival Response to Pesticides and Fertilizers

In order to examine the responsiveness to the actual pesticides of shrimp and toha, shrimps used in the present invention, the results were examined for shrimp and toha in summer and winter respectively under the conditions of four fertilizers and five pesticides. As in 26, the commonly used chemical fertilizers such as compound fertilizer, urea, soluble fertilizer, and chlorinated chloride have 72%, 78%, 83%, and 72% survival rate after 4 days of treatment. On the other hand, the survival rate of shrimps in the pesticide condition was very sharply reduced, and the gadget had reached 0% survival rate (100% lethality) after 1 day, and Lone Star had 60% after 1 day and 37% after 4 days. Survival rate was shown, and in the case of Nong, Myeong-prescription, and Non-bora, the survival rate of 57%, 68%, and 80% was shown after 4 days of treatment, respectively. In particular, the mortality rate of shrimp against insecticide gadgets, which are grade IV low-toxic pesticides for rice weevil, and lone star, a herbicide for year-old weeds, was very high (FIG. 9).

On the other hand, experiments on the same drugs in winter were carried out on the harvested toha harvested during the autumn rice harvest, but the mortality rate was slightly higher than that of summer shrimps. After 4 days of treatment, Nong-Nang, Lone Star, Myeong-prescription, and Non-Bora showed survival rates of 75%, 80%, 88%, and 93%, respectively. On the other hand, the survival rate of toha for various chemical fertilizers showed a high tendency and showed survival rate of about 90% or more even after 4 days of treatment. (FIG. 10).
