Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of goat breeding, and particularly relates to a method for breeding goats by interplanting Pueraria lobata and Broussonetia papyrifera in mountainous areas. BACKGROUND
[0002] Pueraria lobata is a perennial herbaceous vine of Pueraria of Leguminosae, and is fond of warm and humid environment, and is strong in adaptability, and can resist cold, drought and poor soil, but is not resistant to waterlogging. Pueraria lobata can grow in slightly acidic red soil, yellow soil, granite gravel soil, sandy soil, neutral sandy soil and purple soil, and can also grow in rocky mountain, bare mountain, stone bone land, gravel land and karst gravel, as long as there is a gap for rooting, and is preferably cultivated in deep humus soil and sandy soil. Pueraria lobata can grow under the climatic conditions of the highest temperature of 39.1 DEG C, the lowest temperature of -23.1 DEG C and annual precipitation of 329.4 mm, and is not resistant to frost, and the upper part dies when frost occurs, and regenerates from the underground part the next year, and grows fast from the branching period to the flowering period. The suitable growth temperature is 22-26 DEG C, and the fastest growth is at 27-28 DEG C, and Pueraria lobata is suitable for growing in an area with annual precipitation of 800-1000 mm. High temperature and rain in summer are most beneficial to the growth of Pueraria lobata, the main stem can elongate by more than 3 m per day, Pueraria lobata likes light, the stem and leaf are thick and strong, the growth is good, the branches are many, and the ground covering speed is fast. Pueraria lobata can resist diseases and pests, and is resistant to extensive management, and has developed root system, and can absorb deep soil water, and can continue to spread when other plants wilt and stop growing in the drought period, and the branches are interlaced and climb the mountain slope. According to observation, in the burned land, other plants are all burned to death, but Pueraria lobata can grow out of the block roots and grow luxuriantly, and is called as a mountain drought-resistant pioneer plant. Some cold-resistant varieties can grow in the frost-free area in the south all the year round, and can be harvested every 20 days during May to November, and the annual yield of Pueraria lobata is more than 10 tons per mu, and Pueraria lobata is suitable for artificial cultivation, and is a good economic crop suitable for controlling soil erosion in mountainous areas.
[0003] According to data analysis, kudzu (stem, branch, leaf) contains crude protein 20.89%~29.2%, crude fat 2.45%~4.2%, crude fiber 26.55%~34.189%, ash 5.91%~9.97%, calcium 2.11%, phosphorus 0.09%, nitrogen-free extract 30.39%~40.7%, among which the amino acid content accounts for 16% of total nitrogen, arginine nitrogen accounts for 8.8%, lysine nitrogen accounts for 2.0%, crude amino acid nitrogen accounts for 4.63%, robinin 0.17%~0.35%, and adenosine, aspartic acid, glutamic acid, robinin, kaempferol, rhamnose glycoside, etc. In addition, kudzu also contains more minerals and vitamins. The dry matter content in kudzu leaf is 22.3% of fresh grass weight, among which the total energy is 17.53 MJ / kg~18.62 MJ / kg, the digestible energy is 11.51 MJ / kg, and the digestible crude protein is 209 g / kg. The crude protein content can be comparable to excellent legume forage grasses such as winged bean and alfalfa, far higher than columnflower grass and peanut vine, and the crude fiber content is relatively low, the crude ash content is also high, and the calcium content is 1~2 times higher than that of ordinary legume grass. Kudzu is palatable, has high biological yield (can be used as green feed in the south all year round, and can also be made into silage and hay powder), and is a high-quality feed that is favored by cattle, horses, sheep, pigs, rabbits, and other livestock, as well as chickens, ducks, geese, and other poultry. It is a natural high-quality legume forage in the south.
[0004] Broussonetia papyrifera is produced in north and south China, distributed in the Yellow River, Yangtze River and Pearl River basins, often wild or planted in the village near the wasteland, farmland and ditch. It is found in hillside, suburb, river bank, roadside, courtyard, and mostly distributed in patches, mostly in hilly and plain areas below 1600 meters. It likes light, has strong adaptability, can tolerate drought and barren, does not choose soil, and can also grow in water, mostly grows in limestone mountain, and can also grow in acid and neutral soil. The root system has the characteristics of fast growth, fast sprouting and strong tillering, can adapt to the climate of cold and dry in north China and warm and humid in south China, has strong adaptability, and has few diseases and pests.
[0005] The bark, leaf and seed of Broussonetia papyrifera can be used as medicine. The bark tastes sweet and is flat, has the effects of diuresis, swelling, expelling wind and removing dampness. The leaf tastes sweet and is cool, has the effects of clearing heat and cooling blood, removing dampness and killing insects. The seed tastes sweet and is cold, has the effects of tonifying kidney and strengthening tendon, clearing eyesight and diuresis.
[0006] The crude protein content of Broussonetia papyrifera leaf is about 18-24%, has high biological yield, rich nutritional substances and other advantages, contains various bioactive components, has the function of improving the immunity and quality of livestock and poultry, and can play a significant optimization role in the production of ruminants, pigs, poultry, rabbits, etc. It is a new feed source with great potential. In China, the Ministry of Agriculture and Rural Affairs has included it in the feed raw material directory and key non-grain protein feed resources. In promoting antibiotic-free breeding, reducing breeding costs and alleviating the shortage of conventional feed, Broussonetia papyrifera has great potential and advantages.
[0007] The main characteristics of land resources in Guangxi are more mountains and less land, more stones and less soil, the area of mountains, hills and stone mountains accounts for 69.7% of the total area, which is not conducive to mechanized cultivation, and is also not conducive to harvesting and transportation. Originally, it relied on the mountains to eat the mountains, developed goat breeding, and ate weeds outside, and brought back high-quality mutton and organic fertilizer. It is a good project with small labor and high benefit in the mountain area. However, the carrying capacity of natural grass and shrubs in the mountain area is extremely limited, and it is difficult to regenerate after being eaten by sheep, causing soil erosion and ecological destruction, accelerating the process of stone desertification, and having to prohibit grazing.
[0008] The most lacking in southern sheep breeding is high-quality legume forage (protein feed). Taking the sheep breeding in Guangxi as an example, any goat in captivity cannot do without peanut vine with high protein content. Every year, a large amount of peanut vine needs to be purchased from the north at a high price (1600-1800 yuan / ton). Without peanut vine, it is difficult to breed sheep or feed high-priced protein soybean meal, resulting in low benefit and difficulty in making a profit. It can be seen that it is very important to have high-quality legume forage in the south to breed good sheep.
[0009] Many scientific researchers have conducted a lot of research on the forage utilization of broussonetia papyrifera and kudzu vine, and have concluded that both broussonetia papyrifera and kudzu vine have great potential for development. In recent years, broussonetia papyrifera has also been planted on a large scale on cultivated land to develop pig breeding, but broussonetia papyrifera is not conducive to mechanized harvesting and processing. Planting broussonetia papyrifera on cultivated land is obviously inferior to mass food crops in terms of biological yield and harvesting and processing. It is not suitable for the natural growth and utilization of broussonetia papyrifera. There are few scientific research reports on the planting of broussonetia papyrifera in the mountain area for development of breeding. Kudzu vine is famous in the world for its unique medicinal effect and nutritional health function. The relevant scientific activities of variety selection, cultivation technology and product development and utilization of edible and medicinal kudzu vine are very active. Kudzu vine has formed a large-scale planting on cultivated land, but there are few research reports on the selection of forage kudzu vine varieties, cultivation and development of breeding in the mountain area.
[0010] Therefore, in order to optimize the industry in the southern mountain area, it is urgent to provide a "lazy" planting and breeding economic mode which is suitable for the development of the industry in the southern mountain area and has the advantages of no repeated cultivation, no harvesting, no transportation and less labor. SUMMARY
[0011] The purpose of the present application is to provide a method for planting kudzu vine and broussonetia papyrifera in the mountain area. Kudzu vine and broussonetia papyrifera have the biological characteristics of strong adaptability, drought resistance, cold resistance, poor ridge tolerance and strong regenerative ability, and are suitable for planting in the mountain area. They can grow in a mutually dependent manner. The biological yield is high, the nutritional value is high, and the unique medicinal and functional health care effect is provided. Kudzu vine and broussonetia papyrifera are interplanted to develop moderate rotational grazing of goats, and to provide an ecological, healthy and sustainable development mode of high-efficiency planting and breeding industry with low labor input and low cost in the mountain area.
[0012] In order to achieve the above purpose, the present application provides the following technical scheme:
[0013] One of the technical solutions of the present application: provide a mountain area Kudzu interplanting tree for sheep method, comprising the following steps:

[0015] The reason for selecting Kudzu and tree interplanting in the present application is that when Kudzu is planted alone, there is no support, Kudzu interlaces with each other, supports each other, grows towards the sun, forms a Kudzu canopy with a thickness of more than 1 m, the ground is wet, a large amount of rotten leaves breed bacteria and parasites. Goats are afraid of wet and like dry, and like to eat branches and leaves more than 50 cm above the ground, and eating low and wet pasture is easy to be infected with bacteria and parasites, causing gastrointestinal diseases; at the same time, goats are timid and easy to be frightened, and do not dare to enter the dense grassland to feed, and the low and dense vines stir the feet and are easy to frighten the goats and cause the goats to run away, and even entangle the goats or lose the lambs trapped; in addition, goats like to eat tender branches and leaves, in order to prevent goats from overeating tender shoots and leaves, affecting the regeneration of Kudzu, moderate rotational grazing should be adopted.
[0016] Preferably, the selected site is a sunny mountain site as the planting area.
[0017] Preferably, the soil preparation step includes: cutting a fire belt to burn the mountain, using a mixture of soil, soil ash, farm manure, organic fertilizer, water retaining agent and dimethoate to ridge and film in many places of the soil, and puncturing the film when transplanting.
[0018] Preferably, the Kudzu variety is selected to be a cold-resistant large-leaf wild Kudzu.
[0019] More preferably, the cold-resistant large-leaf wild Kudzu includes Guike No. 4, Guike No. 8 and Guike No. 18.
[0020] Most preferably, the cold-resistant large-leaf wild Kudzu is Guike No. 18.
[0021] Preferably, the Kudzu seedling raising time is when the spring rain comes, and the Kudzu seedlings grow 3-4 leaves.
[0022] Preferably, the steps in the routine management include: topping when the tree grows to 1.5 m high, and topping when the Kudzu grows to 1.2 m high.
[0023] Preferably, after grazing, there is also a growth recovery step of Kudzu and tree, which specifically includes: spreading farm manure on the planting ground every spring to improve soil fertility.
[0024] The beneficial technical effects of the present application are as follows:
[0025] The method of intercropping kudzu and paper mulberry in mountainous areas for sheep farming provided by this invention can greatly improve the carrying capacity and reproductive performance of sheep flocks in mountainous areas, reduce feeding costs, reduce the intensity of grazing labor, and improve breeding efficiency.

Any stated value or intermediate value within a stated range, as well as each smaller range between any other stated value or intermediate value within said range, are also included in this invention. The upper and lower limits of these smaller ranges may be independently included or excluded from the range.
[0028] Unless otherwise stated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. While only preferred methods and materials have been described herein, any methods and materials similar to or equivalent to those described herein may be used in the implementation or testing of this invention.
[0029] The terms “include,” “including,” “have,” “contain,” etc., used in this article are all open-ended terms, meaning that they include but are not limited to.
[0030] To achieve the technical objective of this invention—intercropping kudzu and paper mulberry trees in mountainous areas for sheep farming—the following technical solution is provided:
[0031] (1) Selection of kudzu varieties: Select wild kudzu varieties with deep roots and cold resistance, such as the Guige No. 18 wild forage variety bred by Professor Wang Aiqin of the Academy of Agricultural Sciences of Guangxi University. Its roots are thin and long, penetrating the soil to a depth of more than 3 meters. It can take root deep along the rock crevices, absorb water and nutrients from the crevices, and grow strong vines and lush, broad kudzu leaves. Kudzu can spread rapidly and cover the entire ground and rocks, with high biological yield.
[0032] (2) Select and prepare the land: a. Select a sunny mountain site, cut a firebreak and burn the mountain to prepare the land; b. Select a site with good geology and more soil, mix the fermented farm manure with the soil at a ratio of 1:10-20 or mix the organic fertilizer with the soil at a ratio of 1:80-100, add water-retaining agent and landworm spirit according to the product instructions, mix well, and pile up into a ridge with a bottom width of 0.6-1 m, a height of 0.4-0.6 m, and a top width of 0.3-0.5 m; c. Cover the ridge with mulch, press the top end with your hand to form a 10 cm deep indentation, and poke a hole in the center of the plastic film to collect rainwater and soak the soil pile; d. The tree rows are spaced 2-2.5 m apart, and the trees are planted on the ground with a spacing of 1.5-2 m, while the kudzu is planted on the ridge or soil pile between the trees with a spacing of 0.3-0.5 m; e. Collect natural rainwater by building a water storage tank near the mountain stream;
[0033] (3) Seedling raising and transplanting: The tree seedlings are raised 2 months earlier than the kudzu, and the kudzu seedlings are raised when the temperature rises and spring rain arrives. When the kudzu seedlings are 3-4 leaves long, the tree seedlings are already very strong (ensuring that the tree seedlings grow faster than the kudzu), and they are transplanted at the same time and given enough water to establish roots;
[0034] (4) Seedling management: The tree seedlings do not require special management, and the kudzu seedlings are given 2-3% compound water every 10 days for root fertilization. Observe for pests and spray pesticide with the fertilizer water if pests are found. Spray herbicide once to prevent weeds from growing faster than the kudzu. After 3-4 times of fertilization, the kudzu seedlings grow strong and enter the rapid climbing growth period. At this time, the kudzu lateral buds need to be pruned, and the main vine needs to be preserved to ensure that the main vine is strong. At the same time, the vine is guided to climb the tree. When the tree grows to 1.5 m high, it is topped to allow the tree to grow lateral branches as supports for the kudzu. When the main vine of the kudzu grows to 1.2 m high, it is topped to allow it to grow more branches and increase yield.
[0035] (5) Sheep utilization: In May and June, when the kudzu is long and full, the kudzu leaves on the ground will wither due to lack of light, and the kudzu that spreads on the ground will root anywhere and absorb nutrients. At this time, the main stem of the tree is still thin and tender, and it is not suitable for grazing to prevent the tree from being knocked down by sheep. Artificial feeding should be used. When the main stem of the tree grows to more than 4 cm, it can be grazed. To prevent excessive grazing from affecting the growth of the kudzu and the tree, grazing should be done every 10-15 days. In the spring, use horses or donkeys to carry sheep manure or other farm manure to the entire ground to improve soil fertility and achieve high yield of kudzu. In October, the kudzu grows slowly, and the leaves wither in frost. In frost-free areas, the kudzu can grow all year round. Therefore, during the kudzu's lush period, it can be harvested to make hay and silage for feeding during the dry season. It can also be controlled by breeding to regulate the lambing season and reduce the amount of feeding during the dry season.
[0036] The specific implementation is as follows:
[0037] Example 1
[0038] Mountain rattan interplanting with Broussonetia papyrifera for sheep raising:
[0039] (1) Selection of rattan varieties: Select deep-rooted cold-resistant large-leaf wild rattan varieties, such as the wild forage variety Guijia No. 18 developed by Professor Wang Aiqin of the Agricultural Academy of Guangxi University, which has fine and long roots that penetrate into the soil layer up to 3 meters or more, can penetrate into the crevices of rocks and absorb water and nutrients from the crevices, grow thick stems and lush and broad rattan leaves, and can quickly spread and cover the entire ground and rocks with high biological yield;
[0040] (2) Site selection and land preparation: a. Select a sunny mountain site and cut a fire prevention belt for land preparation; b. Select a site with good geology and more soil, mix fermented farm manure with soil at a mass ratio of 1:20, add water retention agent and diquat according to the product instructions, mix well, and pile up a land ridge with a bottom width of 0.6m, a height of 0.4m, and an upper width of 0.3m; c. Cover the land ridge with mulch, press a 10cm deep indentation at the top end, and pierce the center of the plastic film to collect rainwater to soak the soil pile; d. The spacing between Broussonetia papyrifera trees is 2m, and the spacing between plants is 1.5m, which are planted on the ground, while the rattan is planted on the land ridge or soil pile between the plants, with a spacing of 0.3m; e. Select a place where water flows through the mountain to build a water storage tank to collect natural rainwater;
[0041] (3) Seedling raising and transplanting: Broussonetia papyrifera seedlings are raised 2-3 months earlier than rattan seedlings. Rattan seedlings are raised when the temperature rises and spring rains arrive. When the rattan seedlings grow 3-4 leaves, they are transplanted, and the Broussonetia papyrifera seedlings are already very strong (ensuring that the Broussonetia papyrifera seedlings grow faster than the rattan seedlings), and the rattan and Broussonetia papyrifera are transplanted at the same time and irrigated with enough water to establish roots;
[0042] (4) Seedling management: Broussonetia papyrifera seedlings do not require special management. Rattan seedlings are sprayed with 2wt.% compound fertilizer solution every 10 days for root fertilization. Observe for pests and spray pesticides with the fertilizer solution if pests are found. Spray herbicide once to prevent weeds from growing faster than rattan seedlings. Fertilize 3 times, then the rattan seedlings grow strong and enter a rapid climbing growth phase. At this time, remove the mulch and allow the rattan to grow freely. When the Broussonetia papyrifera grows to 1.5m tall, prune it to allow it to grow lateral branches as supports for the rattan. When the rattan climbs to 1.2m high, prune it to allow it to grow more branches and increase yield;
[0043] (5) Sheep utilization, after the 5-6 month Kudzu vine is full of rows, the Kudzu vine on the ground will wither and die because of lack of light, and the Kudzu vine on the ground will root anywhere and absorb nutrients, and the Kudzu vine will grow along the ground where there is a gap. At this time, the main stem of the tree is still relatively tender, and it is not suitable for grazing to prevent the tree from being knocked down by the sheep. Artificial feeding should be used to feed the sheep, and when the main stem of the tree is more than 4 cm in diameter, the sheep can graze and eat. In order to prevent overeating and affect the growth of Kudzu and trees, grazing should be done every 10 days, and every year in the spring, use horses, donkeys, and other farm animals to carry sheep manure or other farm manure to the entire ground to improve soil fertility and obtain high yield of Kudzu. After entering October, the growth of Kudzu is slow, and the leaves wither in the frost period. Kudzu can grow all year round in frost-free areas, so during the Kudzu growing season, dry grass and silage can be harvested for feeding during the dry season, and the breeding season can be controlled to reduce the amount of feeding during the dry season.
[0044] Example 2
[0045] Mountain Kudzu intercropping with trees for sheep breeding:
[0046] (1) Selection of Kudzu varieties: Select deep-rooted and cold-resistant wild Kudzu varieties with large leaves, such as the wild feeding type variety Gui Ge 18 developed by Professor Wang Aiqin of the Agricultural Academy of Guangxi University. The roots are long and can penetrate deep into the soil layer, up to 3 meters or more, and can absorb water and nutrients from the cracks between rocks. The Kudzu vine grows thick stems and lush leaves, and can quickly spread and cover the entire ground and rocks with high biological yield.
[0047] (2) Site selection and land preparation: a. Select a sunny mountain site and cut a fire prevention belt for burning and land preparation; b. Choose a site with good geology and more soil, mix organic fertilizer with soil at a ratio of 1:100, add water retention agent and diquat according to the product instructions, mix well, and pile up a land ridge with a bottom width of 1m, a height of 0.6m, and a top width of 0.5m; c. Cover the land ridge with mulch, and at the top end, press a 10cm deep indentation with your hand, and poke a hole in the center of the plastic film to collect rainwater to soak the soil pile; d. The distance between the trees is 2.5m, and the distance between the plants is 2m, and the Kudzu is planted in the land ridge or soil pile between the trees, with a distance of 0.5m; e. Choose a site near the watercourse, build a water storage tank to collect natural rainwater;
[0048] (3) Seedling and transplanting: Kudzu is 3 months earlier than Kudzu in seedling, Kudzu is planted in spring when the temperature rises and spring rain comes, and Kudzu is transplanted when it grows 3-4 leaves, Kudzu is very strong (ensure that Kudzu grows faster than Kudzu), Kudzu and Kudzu are transplanted at the same time and irrigated with enough water to fix the roots;
[0049] (4) Seedling management, Broussonetia papyrifera seedling does not require special management, every 15 days with 3% compound water spraying root fertilizer, the same observation of insect pests, found insect pests will be pesticide into the fertilizer water and spray, during spraying herbicide, to prevent weeds grow faster than the growth of kudzu vine, after 4 times of topdressing, kudzu vine strong growth, into the rapid growth of climbing, when the film is removed, free to spread growth. When the tree grows to 1.5 m high, top, to let the tree grow branches as a kudzu vine support to carry kudzu vine, when the kudzu vine climbs to 1.2 m high, top, to let it grow more branches, improve the yield of kudzu vine;
[0050] (5) Sheep utilization, 5-6 months kudzu vine full line, the ground kudzu vine leaves due to lack of light and dry, and spread on the ground kudzu vine roots everywhere everywhere, the main stem of the tree is still relatively tender, not suitable for grazing, to prevent the goat feeding will be the tree to fall, should be artificial cutting feeding sheep, when the main stem of the tree grows to 4 cm or more, can be grazing, to prevent excessive grazing affect the growth of kudzu vine and tree recovery, every 15 days grazing 1 times, every spring with horse, donkey, sheep manure or other farm manure spread the entire ground, improve soil fertility to obtain high yield of kudzu vine. After entering October, kudzu vine growth slows down, into the frost period of kudzu vine leaves dry, no frost area kudzu vine can grow all year round, so in the kudzu vine lush period can be harvested into hay and silage to prepare for the dry season feeding, also can be through the control of breeding to regulate the lambing season, reduce the dry season feeding amount.
[0051] Comparative example 1
[0052] Mountain planting tree and sheep:
[0053] Compared with example 1, the difference is that the kudzu vine and the subsequent management of kudzu vine are omitted.
[0054] Comparative example 2
[0055] Mountain planting kudzu vine and sheep:
[0056] Compared with example 1, the difference is that the planting of the tree and the subsequent management of the tree are omitted.
[0057] The effect of the sheep raising method provided in examples 1-2 and comparative examples 1-2 is compared with that of natural mountain sheep raising:
[0058] Kudzu vine and tree intercropping compared with single kudzu vine, intercropping increases the three-dimensional space and photosynthesis of kudzu vine growth, biological yield is high, carrying capacity is 10 times of natural mountain carrying capacity, is 3-4 times of single kudzu vine, that is, 1 mu of natural mountain can raise 0.5 sheep, single kudzu vine can raise 1.5-2 sheep, kudzu vine and tree intercropping can raise 5 sheep (according to the carrying capacity calculation formula in "China southern grassland resources survey method and regulation", the average area of shrub grassland required for 1 goat unit is 0.133hm2 about 1.5 goats per 666.67 m 2 The carrying capacity of 0.5 goats can be achieved in superior pasture (0.74), medium pasture (0.51) and inferior pasture (0.25). Wang Jingling. Study on the carrying capacity of goats in natural shrub grassland [J]. Contemporary Animal Husbandry, 2006(07): 50.
[0059] Compared with the single kudzu, the kudzu and broussonetia papyrifera interplanting is more suitable for grazing and kudzu regeneration. The single kudzu grows creeping and easily entangles the sheep's feet, making the sheep timid and prone to panic and unease in feeding. The kudzu leaves contaminated and trampled by sheep urine and feces are not eaten by sheep, resulting in a large waste of leaves. The trampled kudzu becomes tight and not breathable, which easily infects the kudzu with bacteria and affects its regeneration.
[0060] In addition, compared with the single kudzu and natural mountain grazing, the sheep feeding is more stable in the kudzu and broussonetia papyrifera interplanting, and the grazing time is shortened, greatly reducing the labor of grazing. For example, for the single kudzu, the kudzu grows creeping and easily entangles the sheep's feet, making the sheep timid and prone to panic and unease in feeding. The grazing time needs to be 3-4 hours to eat enough. For the natural mountain grazing, the goats feed on the tender branches and leaves, and eat while walking. The grazing in the morning at 10 o'clock needs to be returned to the pen at 6 o'clock in the evening, lasting for 7-8 hours, and the walking distance is 8-10 kilometers, and the feeding area is very wide.
[0061] Compared with the natural mountain grazing, the kudzu and broussonetia papyrifera interplanting is more nutritious, improves the digestion and conversion rate of feed, reduces the input cost of concentrated feed, greatly improves the reproduction and growth performance of the flock, shortens the reproduction cycle of the ewes, increases the annual production of 0.5 fetuses, and significantly increases the twin lamb rate and multiple lamb rate. The annual lambing rate is increased from 2.25% to 3.4%.
[0062] The above-described embodiments are only to describe the preferred modes of the present application, and are not to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
