Abstract
Description
Technical Field
[0001] The utility model belongs to the field of agricultural infrastructure construction, and in particular relates to a mechanized farmland transformed from hilly and sloping land. Background Art
[0002] Traditional Chinese agriculture focused solely on large-scale cultivation of the land itself. This was particularly true in the hilly and mountainous areas of western China. To survive, our ancestors built terraced fields and sloping land suitable for cultivation. After the founding of the People's Republic of China, a major effort was made to improve farmland infrastructure, resulting in the construction of a large number of standardized farmlands, which significantly contributed to agricultural development. However, much of this sloping land remained unrenovated, resulting in soil erosion, barren land, difficulty in cultivation, impracticality for mechanized farming, and very low yields. Even in these renovated standardized farmlands, the embankments were typically constructed of rough stone, which was not only labor-intensive and material-intensive, but also prone to collapse during heavy rains or flash floods, causing disasters.
[0003] With the expansion of cities, real estate development, transportation construction, ecological migration, etc., a large amount of good flat land has been occupied. The poor land on the hillsides has gradually turned into barren mountains due to being difficult to cultivate and having low yields, which has seriously hindered the mechanized production and sustainable development of agriculture. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the existing technology and provide a mechanized farmland transformed from hilly slopes, so as to solve many problems such as soil erosion, barren land, difficulty in farming, inability to mechanize farming, low yield, and lack of multi-purpose space in existing hilly slopes. The hilly slopes can be transformed into permanent, large-scale mechanized farmland that can be farmed by mechanization and can guarantee a good yield in drought or flood, so as to realize the integrated development and comprehensive utilization of hilly areas.
[0005] In order to solve the above technical problems, the utility model provides a mechanized farmland transformed from a hilly slope. The hilly slope is arranged into a plurality of slope platforms arranged from bottom to top along the longitudinal direction of the slope, and the upper and lower adjacent slope platforms are connected by slopes.
[0006] It includes the construction of a multifunctional terraced three-dimensional planting and breeding space on hilly slopes, a flood control and drainage system, an automatic sprinkler irrigation system, and transportation roads for mechanized farming operations;
[0007] The described ladder-shaped multifunctional three-dimensional planting and breeding space includes at least one ladder building built on a slope platform, at least one elevated planting flat land and at least one basic planting flat land. The top planting flat land is set on the roof of the ladder building. The top planting flat land, the elevated planting flat land and the basic planting flat land are on the same horizontal plane and connected to each other, forming a large area of mechanized farming flat land.
[0008] The described flood prevention and drainage system includes several horizontal drainage branch pipes arranged on the level cultivated land and a longitudinal drainage main pipe connected to the horizontal drainage branch pipes. The longitudinal drainage main pipe communicates with a sedimentation tank, and the water outlet of the sedimentation tank is connected to a pond at the bottom of the slope.
[0009] The described automatic sprinkler irrigation system includes a water storage tank arranged at the top of the slope. The water storage tank is connected to the pond at the bottom of the slope through a water delivery pipe. A high-lift water pump is installed on the water delivery pipe, and the water storage tank is connected to a sprinkler pipe buried in the level cultivated land.
[0010] The described traffic roads for agricultural machinery operations include a climbing road arranged on the slope, a lift platform arranged in the staircase building, and an operation road arranged on the level cultivated land.
[0011] As a further description of the above technical solution:
[0012] The slope of the described slope is < 30°, which is convenient for operation machinery to go up and down.
[0013] As a further description of the above technical solution:
[0014] There is also a stepped planting area on the slope to make full use of land resources.
[0015] As a further description of the above technical solution:
[0016] There is at least one middle planting and breeding layer in the middle of the staircase building. The middle planting and breeding layer can be used for crop planting in the same way as the top planting flat ground, or for soilless cultivation or livestock and poultry breeding. The breeding manure can also be used as organic fertilizer to increase the yield of planted crops.
[0017] As a further description of the above technical solution:
[0018] There is also a multi-functional layer at the bottom of the staircase building. The multi-functional layer can be used for agricultural and sideline product processing, storage, livestock and poultry breeding, office and residence, and / or leisure and entertainment.
[0019] As a further description of the above technical solution:
[0020] To enable the middle planting and breeding flat ground and the stepped planting area on the slope to have sunlight and meet the growth needs of animals and plants, vertical lighting wells are provided on the top planting flat ground and the raised planting flat ground. The density of the lighting wells is based on being able to meet the normal growth of animals and plants below.
[0021] As a further description of the above technical solution:
[0022] The top planting flat land and the elevated planting flat land include, from bottom to top, a steel-concrete structural layer, a leak-proof layer, a natural flow water storage layer, a sand-isolating layer, a carbon water-retaining and breathable layer, and an improved planting soil layer. The steel-concrete structural layer is 150 to 200 mm thick, the leak-proof layer is 10 mm thick, the natural flow water storage layer is 300 mm thick, the sand-isolating layer is 50 mm thick, the water-retaining and breathable layer is 200 mm thick, and the improved planting soil layer is 900 mm thick. This not only satisfies the growth space of plant roots, but also can be combined with a flood control and drainage system to prevent mountain torrents. That is, the planting flat land is elevated by building terraced buildings or assuming pile foundations, and a leak-proof layer and a water storage layer are set on the planting flat land, and a horizontal drainage branch pipe is buried to divert mountain water to the pond at the bottom of the slope to prevent natural disasters such as embankment collapse and mountain torrents.
[0023] As a further description of the above technical solution:
[0024] It also includes a self-generated power supply system, which is composed of photovoltaic components on the outer wall of the stepped building, slope air ducts, solar power generation chimneys on the top of the slope and / or wind turbines and transmission cables on the mechanized farming flat land, using green energy such as solar energy and wind energy to meet the self-sufficient electricity needs of hilly slopes.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0026] 1. The mechanized farmland transformed by the present invention is different from the general standard farmland. Instead, it is a one-time transformation of low-yield hilly sloping land into a permanent large-area high-quality farmland that can be cultivated by mechanization and has a stable yield regardless of drought or flood. While transforming the sloping land, it forms a usable space that is several times larger than the occupied area. According to needs, it can be standardized and constructed into a space with multiple uses such as soilless cultivation, poultry and livestock breeding, agricultural and sideline product processing, waste treatment, organic fertilizer production, agricultural and sideline product storage, office and living, leisure and entertainment, etc. There is no need to select another site for construction, which saves a lot of capital investment and realizes the integrated development of hilly areas.
[0027] 2. While renovating the hilly slopes, a comprehensive system for preventing flash floods was established. Instead of building high, thick stone embankments, the land was elevated for planting. A leak-proof layer, a water storage layer, and horizontal drainage pipes were installed on the elevated land to divert mountain water to ponds at the bottom of the slope, minimizing the risk of natural disasters such as embankment collapse and flash floods.
[0028] 3. It can meet the operating requirements of various small and medium-sized machines and realize mechanized production. BRIEF DESCRIPTION OF THE DRAWINGS
