Description

Technical Field

[0001] The utility model relates to the technical field of rice planting, in particular to a tillage layer structure for a newly reclaimed rice field. Background Art

[0002] my country's main rice-producing regions include the Northeast, Yangtze River, and Pearl River basins. Rice-sown area accounts for approximately a quarter of the country's total grain crop area, and its production contributes to over half of the country's total grain crop production. Besides being edible, rice can also be used for winemaking, sugar production, and animal feed. The formation of paddy soils is influenced by both human activities and natural factors. The long-term flooding during rice cultivation creates a constant alternation of oxidizing and reducing environments. The continuous leaching and deposition of paddy soil materials during cultivation creates unique profiles in paddy fields, typically with a relatively heavy clay subsoil. Paddy soils are widely distributed and come from a variety of parent soils. Organic matter and other nutrient content varies greatly between parent soils, but they gradually become standardized during soil formation, significantly narrowing the gaps in organic matter and nutrient content and achieving uniformity and stability. This standardization during paddy soil formation also opens the door to standardized and widespread use of rapid artificial paddy soil construction technology.

[0003] The soil conditions for the topsoil layer suitable for rice cultivation mainly consider the following parameters: soil pH, soil texture, soil bulk density, soil layer thickness, and organic matter content. The optimal soil pH is 5.0–6.5, the soil texture should be at least sandy loam, the optimal soil bulk density is 1.0–1.4 g / cm³, the topsoil layer thickness should be greater than 15 cm, and the soil organic matter content should be above 1% (or above 1.5% in some areas). Therefore, the rapid construction of the topsoil layer in rice fields requires specific consideration of these parameters. In practice, it is necessary to combine relevant techniques such as imported soil and soil improvement to construct a topsoil layer suitable for rice growth. Therefore, it is necessary to conduct random inspections of paddy field soils. Existing paddy field structures are essentially based on plowing on the parent soil before planting. The existing paddy field structure lacks distinct stratification, and the targets for subsequent soil inspections are not clearly defined. Furthermore, fertilizer is generally applied directly on top, resulting in low infiltration efficiency. Furthermore, the paddy fields are directly exposed, resulting in rapid water loss and the need for daily water replenishment. Therefore, improvements to the paddy field structure are possible. Utility Model Content

[0004] The utility model provides a newly reclaimed rice field tillage layer structure, which is convenient for subsequent maintenance and random inspection of the rice field, has good heat preservation effect, low water loss efficiency, and can automatically supply fertilizer in real time.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A newly reclaimed rice field tillage layer structure includes a mother soil layer, a plowed soil layer, and a nutrient mixing layer. The mother soil layer, the plowed soil layer, and the nutrient mixing layer are arranged in sequence from bottom to top. A ridge is gathered above the mother soil layer, and the ridge surrounds the plowed soil layer and the nutrient mixing layer. A ditch is provided between the ridge and the plowed soil layer. The plowed soil layer is coated with a first concrete layer near the ditch, and the nutrient mixing layer is coated with a second concrete layer. The top of the second concrete layer is lower than the height of the top of the ridge. A side of the first concrete layer is provided with a reserved hole, and a number of the reserved holes are equidistantly provided along the length direction of the first concrete layer.

[0007] Furthermore, a plurality of balancing water pipes are inserted into the side of the first concrete layer. A through groove is provided on the side of the balancing water pipe away from the parent soil layer. A stopper is clamped inside the balancing water pipe, and a filter is embedded inside the stopper.

[0008] Furthermore, the reserved hole is arranged between two balancing water pipes, a fertilizer supply pipe is inserted into the reserved hole, a connecting elbow is fixed at the end of the fertilizer supply pipe extending out of the reserved hole, all the connecting elbows are threadedly connected to the connecting pipe away from the end of the reserved hole, and a fertilizer supply port is provided at one end of the connecting pipe.

[0009] Furthermore, a plurality of through holes are provided on the outside of the fertilizer supply pipe, and a one-way film is bonded to the inner wall of the fertilizer supply pipe, and the one-way film covers each through hole.

[0010] Furthermore, the nutrient mixed layer includes a sand layer close to the plowed soil layer, the sand layer is covered with a ferromagnetic nanoparticle layer, the ferromagnetic nanoparticle layer is covered with a sand-soil mixed layer, and the sand-soil mixed layer is provided with a plurality of arc grooves.

[0011] Furthermore, the thickness of the tilled soil layer is 20 cm, the thickness of the nutrient mixed layer is 10 cm, wherein the thicknesses of the sand layer, the ferromagnetic nanoparticle layer and the sand-soil mixed layer are 6 cm, 1 cm and 3 cm respectively.

[0012] In summary, the beneficial technical effects of the present invention are as follows: the present invention sets a balancing water pipe to balance the water level inside the ditch and the water level inside the plowed soil layer, and can automatically supply water. During daily planting and maintenance, the water level inside the ditch can be visually checked, and the soil inside the plowed soil layer can be quickly sampled, which is convenient for subsequent rice field maintenance. The present invention allows fertilizer to reach the plowed soil directly, and its supply rate and supply amount are limited by the size of the through hole. Fertilizer can be supplied slowly and continuously to prevent plants from being burned by fertilizer. At the same time, fertilizer can be automatically replenished, and a one-way membrane is provided to prevent water from seeping into the plowed soil layer. The nutrient mixing layer of the present invention includes a sand layer close to the plowed soil layer, a ferromagnetic nanoparticle layer covering the sand layer, a sand-soil mixing layer covering the ferromagnetic nanoparticle layer, and a plurality of arc-shaped grooves are provided on the sand-soil mixing layer. The arc-shaped grooves can be used for the placement of solid organic matter or solid fertilizers. The sand-soil mixing layer is used to carry the material inside the arc-shaped groove 20. At the same time, the sand layer below can facilitate the penetration of the material inside the arc-shaped groove, and a ferromagnetic nanoparticle layer is provided to fill the shortcoming of poor water retention of the sand layer, which can reduce the water loss inside the plowed soil layer and keep warm at the same time.
