Description

Technical Field

[0001] The invention relates to the technical field of crop planting, and more particularly to a high-protein composite forage planting method and a matching planting device thereof. Background Art

[0002] High-protein compound forage refers to a nutritious high-protein compound feed provided to livestock and other animals by planting, mixing or processing a variety of forages. This compound forage is usually composed of several forages with complementary advantages, such as soybeans and corn, which effectively improves the nutritional value of the feed and meets the needs of animal growth and production. The lack of protein forage is the main factor restricting the development of animal husbandry in North China. Therefore, it is of great significance to introduce high-quality protein forage whole soybeans into the silage corn planting model and explore its special planting technology, which has broad application prospects.

[0003] When planting high-protein composite forage, it is necessary to use a high-protein composite forage planting method. Among them, the "method for improving the quality of silage corn feed based on creeping forage soybeans" disclosed in the publication number "CN113349007B" clarifies that the composite planting of soybeans and silage corn and mixed harvesting of silage can increase the yield and crude protein content of silage corn feed, but it does not specify what kind of planting pattern can significantly improve the quality of silage feed while not reducing the quality, that is, it does not consider the specific planting pattern.

[0004] In addition, there are many defects in the actual use of planting methods with similar structures, such as: corn and soybean intercropping is widely planted in North China, and most of them are mainly aimed at food crop production, which is significantly different from forage production in terms of planting mode, harvesting method and target product, and conventional corn and soybean intercropping with forage as the main production target has strong randomness in production, unreasonable planting mode, often only focusing on high yield, while ignoring the comprehensive quality of forage, and there are problems such as waste of resources and low land utilization rate. Therefore, it is necessary to provide a new high-protein composite forage planting method and combine it with supporting devices to solve the above problems. Summary of the invention

[0005] In view of this, the present invention provides a high-protein composite forage planting method, which adopts a strip planting method and can directly use the harvested crops for feeding livestock such as beef cattle without the need to add other protein feeds. It can also effectively increase the per-acre yield of silage crops and the protein and starch content, thereby improving land utilization.

[0006] To achieve the above object, the present invention provides a high-protein composite forage planting method, which intercrops silage corn and soybeans in strips, comprising the following steps:

[0007] S1, first plant two corn plants in one hole;

[0008] S2, planting 10-20 soybean plants continuously;

[0009] S3. Repeat the steps of S1 and S2 to achieve strip intercropping of corn and soybean.

[0010] Preferably, the distance between corn and soybeans in step S2 is 40 cm.

[0011] Preferably, in step S2, 15 soybean plants are planted continuously.

[0012] 4. The high-protein composite forage planting method according to claim 1, characterized in that in the step S2, the soybean plant spacing is 10 cm and the row spacing is 40 cm.

[0013] The present invention also provides a high-protein composite forage grass planting device for realizing the above-mentioned high-protein composite forage grass planting method, comprising a frame and a furrowing disc, wherein the furrowing disc is connected to the bottom of the frame through a support rod, and a soybean seed storage box and a corn seed storage box are provided on the frame, and the outer side walls of the soybean seed storage box and the corn seed storage box are respectively connected to a seed guide tube, and the seed guide tube is used to guide the soybean seeds and the corn seeds into the seed holes, and the soybean seed storage box and the corn seed storage box are alternately planted so that the soybean seeds and the corn seeds are planted in strips at intervals.

[0014] Preferably, the soybean seed storage box and the corn seed storage box are both disc-shaped, and a plurality of soybean seed holes and a plurality of corn seed holes are respectively arranged on the side walls of the two boxes at circumferential intervals. When the soybean seed storage box and the corn seed storage box rotate, the soybean seed holes and the corn seed holes are respectively alternately connected to the seed guide pipes, so that the soybean seeds and the corn seeds are alternately guided into the seed holes.

[0015] Preferably, the planting device also includes a first gearbox and a second gearbox, the first gearbox is transmission-connected to the soybean seed storage box for controlling the rotation of the soybean seed storage box, and the second gearbox is transmission-connected to the corn seed storage box for controlling the rotation of the corn seed storage box.

[0016] Preferably, the planting device also includes a first seeding device and a second seeding device, the first seeding device is arranged between a soybean seed storage box and a seed guide tube, and is used to control the seeding of soybean seeds in the soybean seed storage box, and the second seeding device is arranged between a corn seed storage box and another seed guide tube, and is used to control the seeding of corn seeds in the corn seed storage box.

[0017] Preferably, the top end of the support rod is fixedly connected to the frame, and the bottom end of the support rod is rotatably connected to the ditching disc.

[0018] It can be seen from the above technical solutions that, compared with the prior art, the high-protein composite forage planting method and planting device disclosed in the present invention can sow corn and soybeans in a predetermined order and interval in a planting row, so as to realize a precise strip-interval planting mode of corn and soybeans, and the sowing speed is fast, the operation efficiency is high, and manpower and time costs can be saved. In combination with a specific strip-interval planting mode, the per-acre yield of the obtained corn and the protein and starch content can be significantly improved, and the yield and quality are greatly improved compared with the prior art, and the utilization rate of the land is improved. When the planting mode of 2 corn plants and 15 soybean plants is followed, the crude protein content of the obtained crop is about 57.03% higher than that of silage corn, the crude fat content is about 51.7% higher, the relative feeding value is about 28.4% higher, and the relative feeding value is about 28.45% higher. The overall protein content exceeds 14%, which can be directly used for feeding livestock such as beef cattle without the need to add other protein feeds. Compared with the crops obtained by the strip planting mode, the total yield finally obtained by the planting mode set by the present invention is significantly better than that of the crops obtained by the strip planting mode.

[0019] In addition, the one-hole two-plant planting method adopted by the present invention can effectively reduce the impact of the shading effect of corn on the growth and development of soybeans. At the same time, this planting pattern adopts a strip composite planting method, utilizing the combination of tall and short-stalk crops, the more common corn and soybean strip composite planting pattern, which significantly improves the ventilation and light transmittance of corn, fully utilizes the edge row effect of corn, and improves the yield and quality of corn and soybeans.

[0020] Moreover, in the prior art, silage corn is rich in carbohydrates and is the main source of silage, but its protein content is low and cannot meet the protein needs of livestock. The protein content of soybean plants is as high as 20% or more during the grain filling stage, and it has the characteristics of high-quality legume forage. However, soybean silage fermentation alone often exhibits an unpleasant odor and high butyric acid due to its low water-soluble carbohydrate content and high buffering capacity, resulting in poor silage quality and a low success rate. The present invention, by planting corn and soybeans according to a specific planting pattern and harvesting them, significantly improves the fermentation success rate due to the addition of soybeans in the subsequent fermentation process, which balances nutrition.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a high-protein composite forage planting method, which adopts a strip planting method to intercrop corn and soybeans, and comprises the following steps:

[0028] S1, first plant two corn plants in one hole;

[0029] S2, planting 10-20 soybean plants continuously;

[0030] S3. Repeat the steps of S1 and S2 to achieve strip intercropping of corn and soybean.

[0031] Experimental Example 1: Comparison between strip intercropping and monocropping

[0032] Five treatment groups A1-A5 were set up respectively. Group A1 was planted with two corn plants in one hole first, and then 20 soybean plants were planted continuously; Group A2 was planted with two corn plants in one hole first, and then 15 soybean plants were planted; Group A3 was planted with two corn plants in one hole first, and then 10 soybean plants were planted; Group A4 was planted with two corn plants in one hole first, and then 4 soybean plants were planted; Group A5 was planted with two corn plants in one hole first, and then 2 soybean plants were planted; and two control groups were set up. Control group CK1 only planted corn, and control group CK2 only planted soybeans. The planting patterns are shown in Table 1. The final yield is shown in Table 2.

[0033] Table 1 Planting patterns in different treatment groups

[0034]

[0035] As shown in Table 2, the yield of treatments A1 and A2 was significantly higher than that of other treatments. There was no significant difference between treatments A4 and A5 and the monoculture treatment of corn, but all treatments were significantly higher than the monoculture treatment of soybean. The treatment with the best yield performance was the treatment of corn:soybean = 2:15, which increased the yield of corn by 9.84% compared with the control.

[0036] Table 2 Corn and soybean yields in different treatment groups

[0037]

[0038]

[0039] Table 3 Yield per unit area of ​​corn and soybean in different treatment groups

[0040]

[0041] The yield per unit area is the actual yield of the crop in the intercropping system divided by the proportion of the crop in the intercropping system, that is, the theoretical yield that can be achieved if the yield of the intercropping pattern of the crop is planted in all plots. The yield per unit area can effectively reflect the growth of different crops in the intercropping system. The yield per unit area of ​​different treatment groups is shown in Table 3. It can be seen from Table 3 that the yield per unit area of ​​corn in all intercropping treatments is higher than that of the control treatment, indicating that the planting pattern makes full use of the corn edge effect and the nitrogen fixation of soybeans to promote the growth of corn. The yield per unit area of ​​soybeans in all intercropping treatments is lower than that of the control treatment, but there is no significant difference between the A1 and A2 treatments and the soybean monoculture treatment. Moreover, with the decrease in the number of soybean plants, the yield per unit area decreases significantly, indicating that with the increase in the proportion of corn in the intercropping pattern, it competes for more nutrients, water and sunlight, which seriously affects the production of soybeans. The analysis of the comprehensive competitiveness index Asm shows that corn is in a competitive advantage and soybeans are in a competitive disadvantage. The land equivalent values ​​(LER) of all intercropping treatments were greater than 1, indicating that the strip intercropping pattern was beneficial to the yield of corn and soybeans and improved land use efficiency.

[0042] Table 4 Effects of different treatment groups on the growth and development of corn and soybean

[0043]

[0044] The effects of different treatment groups on the growth and development of corn and soybean are shown in Table 4. It can be seen from Table 4 that the weight of corn per plant in all strip intercropping treatment groups is higher than that in the control treatment group, and some treatments have significant differences. There is no significant difference in the weight of soybean per plant between intercropping treatment and monocropping treatment. Comprehensive analysis shows that the yield of both soybean and corn per plant in A1, A2, and A3 treatments is better than that in A4 and A5 treatments, and the difference is significant, indicating that in strip planting, when the number of corn plants remains unchanged, the number of soybean plants should not be less than 10, otherwise it will affect the yield of this planting pattern.

[0045] Table 5 Effects of different treatment groups on corn quality

[0046]

[0047] The effects of different treatment groups on corn quality are shown in Table 5. As shown in Table 5, all strip intercropping treatment groups showed increased starch and protein content compared with the control group. The high starch content of silage corn can provide a high-quality energy source. The nitrogen fixation of soybeans provides more nitrogen to the soil for corn use, which increases the protein content of silage corn. It can be seen that corn-soybean intercropping is an effective way to increase the protein content of silage corn. The quality of corn can be effectively improved by planting corn and soybeans in strips.

[0048] Table 6 Analysis of silage quality under different treatments

[0049]

[0050] At the soybean grain filling stage, when the corn milk line was about 1 / 2, a fresh corn and soybean sample with a width of 0.3m in the middle of each treatment was taken, cut into small sections of 1-2cm, put into silage bags, vacuumed and sealed to avoid light, fermented at room temperature for 60 days, sampled, dried, and the silage quality was measured as shown in Table 5. It can be seen that with the increase in the number of soybeans planted in the intercropping pattern, its protein content and fat content increased significantly, but the relative feeding value showed a trend of first increasing and then decreasing. Comprehensive analysis showed that the treatment quality of 2 corn plants and 15 soybean plants was the best. When the soybean plant increased to 20 plants, its fiber content increased, and the relative feeding value RFV decreased significantly.

[0051] It can be seen that, considering the total yield, competitive relationship and quality of each treatment, it is believed that the treatment effect of the strip planting pattern of 2 corn plants and 15 soybean plants according to the prepared high-protein composite forage planting device is the best. After the above treatment, the total yield of corn and soybeans finally obtained is not lower than that of silage corn, but the quality is significantly higher than that of silage corn. Among them, the treatment group with the best effect has a crude protein content of about 57.03% higher than that of silage corn, a crude fat content of about 51.7% higher, and a relative feeding value of about 28.4% higher. The protein content of the treatment group with the best effect exceeds 14%. The corn and soybeans in the treatment group of the present invention can be directly mixed and used for feeding livestock such as beef cattle without the need to add other protein feeds, and the production cost and land use efficiency are significantly improved.

[0052] It should be noted that the strip intercropping method adopted by the present invention significantly improves the yield of corn and soybeans harvested compared to the traditional planting mode. The intercropping system effectively utilizes light, heat and water resources, improves land utilization and crop growth efficiency. And due to the reasonable layout of soybeans and corn, the biomass and quality of silage crops are improved. In addition, the use of chemical fertilizers is reduced by the above-mentioned strip intercropping planting mode. The nitrogen fixation of soybeans also provides an additional source of nutrition for corn, which can effectively reduce the use of chemical fertilizers and improve soil structure, thereby improving production efficiency.

[0053] Experimental Example 2: Comparison between strip intercropping and belt planting patterns

[0054] Four treatment groups were set up respectively. Group A1 was planted with 2 rows of corn and 10 rows of soybeans; Group A2 was planted with 2 rows of corn and 8 rows of soybeans; Group A3 was planted with 2 rows of corn and 6 rows of soybeans; Group A4 was planted with 2 rows of corn and 4 rows of soybeans. The corn plant spacing, corn row spacing, corn soybean spacing, corn and soybean spacing, and soybean spacing were 15 cm, 30 cm, 50 cm, and 40 cm, respectively. The specific planting patterns are shown in Table 7.

[0055] Table 7 Strip planting pattern

[0056]

[0057] The final yields of different strip planting patterns are shown in Table 8:

[0058] Table 8 Yields of different strip planting patterns

[0059]

[0060] It can be seen from Table 6 that the total yield per mu of different strip planting patterns is between 2874.82-3236.95 kg. Compared with the yield per mu of the strip planting method in Experimental Example 1, the yield per mu of the strip planting method is between 3069.89-3362.86 kg, which is higher than that of the strip planting method.

[0061] The treatment of planting 2 corn plants and 15 soybean plants in strips has a corn and soybean plant ratio of 2:15, which is converted into a strip planting pattern of 2 rows of corn and 10 rows of soybeans (this planting pattern can achieve a corn and soybean planting plant ratio of 2:15). After comparison, it can be found that the yield of the strip planting method is 3362.86 kg / mu, which is significantly higher than the 2874.82 kg / mu of the strip planting method.

[0062] In summary, considering the total yield, competitive relationship and quality of each treatment, combined with the results of corn and soybean silage detection in proportion, it is believed that the treatment effect of 2 corn plants and 15-20 soybean plants in the strip planting mode is the best. According to the above treatment, the total yield of the final crop is significantly better than that of the strip planting mode, and the total quality of the crop is significantly better than that of silage corn. It can be seen that the specific strip planting mode in the present invention not only realizes the efficient intercropping of corn and soybeans, improves the biological yield and silage effect, but also significantly improves the protein content of crops, reduces production costs, improves soil structure, and has a positive impact on agricultural production.

[0063] At the same time, in order to realize the mechanized planting of the above-mentioned high-protein composite forage grass seed method, thereby improving production efficiency and reducing labor costs, the present invention provides a high-protein composite forage grass planting device used in the above-mentioned planting method, please refer to the attached Figure 1-2 , is a high-protein composite forage planting device disclosed in the present invention, comprising a frame (not shown in the figure), a furrowing disc 1, a support rod 2, a soybean seed storage box 3, a corn seed storage box 4, and a seed guide tube 5.

[0064] The furrowing disc 1 is connected to the bottom of the frame through a support rod 2, the top of the support rod 2 is fixedly connected to the frame, and the bottom end of the support rod 2 is rotatably connected to the furrowing disc 1. A soybean seed storage box 3 and a corn seed storage box 4 are provided on the frame, and the outer walls of the soybean seed storage box 3 and the corn seed storage box 4 are respectively connected with a seed guide tube 5, and the seed guide tube 5 is used to guide the soybean seeds and corn seeds into the seed holes. The soybean seed storage box 3 and the corn seed storage box 4 are alternately planted so that the soybean seeds and corn seeds are planted in strips at intervals.

[0065] Specifically, two independent seed storage boxes are designed to store corn seeds and soybean seeds respectively. The storage boxes have sufficient capacity to meet the sowing needs of a certain area. An adjustable number of seed discharge ports are set at the bottom of the storage box to control the outflow speed and quantity of seeds.

[0066] Use a rotating seeding disc or air suction seeding device to ensure that the seeds can fall accurately into the soil. For corn seeding mechanisms, larger seeding holes are designed to accommodate the size of corn seeds, and for soybean seeding mechanisms, the seeding holes are correspondingly smaller.

[0067] The silage corn variety used in the following examples is Deka 688, and the forage soybean variety is Pudou 5110.

[0068] like Figure 1 As shown, the planting device in this embodiment adopts a rotary seeding disc for sowing, which can be powered by a tractor or other power equipment, and transmits power to the sowing mechanism through transmission shafts, gears and other transmission components. The transmission system can achieve stable speed control, and the sowing speed and interval of different seeds can be controlled through different gear ratios.

[0069] The soybean seed storage box 3 and the corn seed storage box 4 are both disc-shaped, and a plurality of soybean seeding holes and a plurality of corn seeding holes are respectively arranged on the side walls of the two boxes at intervals along the circumferential direction. When the soybean seed storage box 3 and the corn seed storage box 4 rotate, the soybean seeding holes and the corn seeding holes are alternately connected to the seed guide pipe 5, so that the soybean seeds and the corn seeds are alternately guided into the seed holes.

[0070] It should be noted that by controlling the number of soybean seeding holes and corn seeding holes and the interval setting relationship between the two, the interval seeding of soybeans and corn can be achieved. For example, 10 soybean seeding holes are continuously set on the side wall of the soybean seed storage box 3, and then no soybean seeding holes are set at the next position, but a corn seeding hole is set on the side wall of the corn seed storage box 4. Then, when the soybean seed storage box 3 and the corn seed storage box 4 rotate at the same time, 10 soybeans can be planted first, and then one corn can be planted. Similarly, other circumferential positions on the side walls of the soybean seed storage box 3 and the corn seed storage box 4 can be set as needed to achieve different planting requirements for the number of soybeans and the number of corns. If you want to achieve the sowing of two corns in one hole, the aperture of the corn seeding hole can be set accordingly to achieve the desired effect.

[0071] The planting device also includes a first gearbox 6 and a second gearbox 7. The first gearbox 6 is connected to the soybean seed storage box 3 for controlling the rotation of the soybean seed storage box 3. The second gearbox 7 is connected to the corn seed storage box 4 for controlling the rotation of the corn seed storage box 4.

[0072] It should be noted that, by configuring the first gearbox 6 and the second gearbox 7 , the rotation speeds of the soybean seed storage box 3 and the corn seed storage box 4 can be changed accordingly, thereby meeting the requirements of different planting distances.

[0073] It can be understood by those skilled in the art that if two or more strip plantings are required at the same time, it is only necessary to increase the number of corresponding soybean seed storage boxes 3 and corn seed storage boxes 4 and the first gearbox 6 and the second gearbox 7 and other devices, and arrange the outlets of the seed guide tubes 5 of each soybean seed along the same horizontal straight line, and arrange the outlets of the seed guide tubes 5 of each corn seed along another horizontal straight line, and then set different starting rotation positions of the soybean seed storage boxes 3 and the corn seed storage boxes 4 at the starting position of sowing. For example, in the planting method of corn-soybean 2:15, the first large The first soybean seeding hole of the bean seed storage box 3 is aligned with the 11th soybean seeding hole of the second soybean seed storage box 3, so that at the end, the first soybean is planted on the first row, and the 11th soybean is planted on the second row side by side. After 15 soybeans are planted on the first row, two plants per meter are sown in one hole. After the 5th soybean (that is, the 11th to 15th soybeans) are planted on the second row, two plants of corn are planted in one hole. In this way, the effect of simultaneous planting of multiple rows is achieved, and the starting position of the corn seed storage box 4 is adaptively adjusted according to the position of the soybean seed storage box 3.

[0074] like Figure 2 As shown, unlike the rotary seeding disc, the planting device in this embodiment uses an air suction seed metering device instead of a rotary seeding disc for sowing.

[0075] The planting device also includes a first seeding device 8 and a second seeding device 9. The first seeding device 8 is arranged between the soybean seed storage box 3 and a seed guide tube 5, and is used to control the seeding of soybean seeds in the soybean seed storage box 3. The second seeding device 9 is arranged between the corn seed storage box 4 and another seed guide tube 5, and is used to control the seeding of corn seeds in the corn seed storage box 4.

[0076] Specifically, the soybean seed storage box 3 and the corn seed storage box 4 can be disc-shaped, or elliptical or polygonal with the bottom edge tilted downward to avoid seeds remaining in the soybean seed storage box 3 and the corn seed storage box 4 and ensure the smooth discharge of seeds. The first seeding device 8 and the second seeding device 9 are both air-suction seeding devices. The first seeding device 8 and the second seeding device 9 can be connected to a controller (such as a PLC) at the same time to control the alternating seeding of seeds in the soybean seed storage box 3 and the corn seed storage box 4, so that the soybean seeds and corn seeds finally sown can achieve the effect of interval sowing. The method of alternating seeding is to make the first seeding device 8 and the second seeding device 9 work alternately, which is the prior art and will not be repeated here.

[0077] It should be noted that the sowing of two corn plants in one hole can be achieved by adjusting the structure of the seeding disc, for example, increasing the number of seed suction holes. The air-suction seeding device mainly relies on the seed suction holes on the seeding disc to absorb seeds to achieve seeding. Usually, the distribution of the seed suction holes on the seeding disc is designed according to the requirements of single-seed sowing. The seeding disc can be modified to increase the number of seed suction holes at a suitable position. The single row of seed suction holes originally distributed at a certain spacing can be doubled by adding new seed suction holes between the original seed suction holes or at a suitable position without affecting the adsorption effect and seed flow. In this way, in the process of adsorbing seeds, two seeds can be adsorbed at the same time, thereby achieving two plants in one hole; or the shape and size of the seed suction holes can be changed, and the shape and size of the seed suction holes can be appropriately adjusted to meet the requirements of adsorbing two seeds at the same time. The existing seeding device that can realize the planting of two corn plants in one hole can also be used in the present invention to replace the above scheme.

[0078] It can be understood by those skilled in the art that if two or more strip plantings are required at the same time, it is only necessary to increase the number of corresponding first seed row devices 8 and second seed row devices 9, wherein multiple first seed row devices 8 can share one soybean seed storage box 3 at the same time, or multiple soybean seed storage boxes 3 can be set to increase the seed storage capacity, and the same is true for the corn seed storage box 4, and the outlets of the seed guide tubes 5 of each soybean seed are arranged along the same horizontal straight line, and the outlets of the seed guide tubes 5 of each corn seed are arranged along another horizontal straight line, and then at the starting position of sowing, different first seed row devices 8 and second seed row devices 9 are arranged in sequence at the position where the first seed is planted at 15 seeds. For example, in the planting method of corn-soybean 2:15, the first first seed-rower 8 continuously plants 15 soybeans on the first strip (that is, planting starts from the first of the 15 soybean seeds), and the first seed-rower 8 on the second strip in parallel continuously plants 5 soybeans (that is, planting starts from the 11th of the 15 soybean seeds). After 15 soybeans are planted on the first strip, two plants per meter are sown in one hole, and after the fifth soybean (that is, the 11th to 15th soybeans) are planted on the second strip, two corn plants are planted in one hole. In this way, the effect of simultaneous planting of multiple strips is achieved, and the setting of the second seed-rower 9 is adaptively adjusted according to the first seed-rower 8.

[0079] It should be noted that the planting device in the present invention can be installed on tractors, trenchers and other devices for combined use, so that corn and soybean seeds can be intercropped after trenching. Handles and other structures can also be set on the frame. After the trencher performs trenching and other preliminary steps, the operator pushes the planting device forward. Compared with the former, the latter does not require additional machine assistance, so the cost is lower, such as the cost of renting or purchasing machinery and the required fuel consumption.

[0080] In addition, in order to further optimize the above technical solutions, relevant sensors can also be installed, such as temperature sensors, cameras, buzzers, etc., to monitor the working status of the seeder in real time, such as temperature, sowing speed, seed stock, etc. When an abnormal situation occurs, an alarm signal will be issued in time to remind the operator to deal with it.

[0081] In the specific planting process, the schematic diagram of the final planting product after staggered planting using the high-protein composite forage planting device of the present invention is as follows Figure 3 shown.

[0082] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
