Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of farmland management, in particular to a fish-eye bubble management method for slope farmland. BACKGROUND

[0002] Slope farmland refers to dry land distributed on a hillside, which is characterized by poor ground flatness and prone to water and soil loss, resulting in low crop yield. Slope farmland usually exists on slopes of 6° to 25°, which is not conducive to water and nutrient retention and is prone to soil erosion, thereby affecting crop growth and yield. Fish-eye bubbles, also known as waterlogged land in farmland, are mainly formed by surface runoff and interflow water accumulation at low points in the field. A piece of "fish-eye bubble" like a scar not only wastes farmland resources and increases the difficulty of large-scale operation of large machinery, but more importantly, it causes water and soil loss to black soil, which is a "bump" in the minds of farmers when planting. Therefore, there is an urgent need for a fish-eye bubble management method for slope farmland. SUMMARY

[0003] In view of this, the present application provides a fish-eye bubble management method for slope farmland, which solves the problem of water and soil loss caused by fish-eye bubbles in slope farmland and increases the difficulty of large-scale operation of large machinery, and reduces the waste of farmland resources.

The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] EMBODIMENT

[0034] The present application provides a fish eye bubble treatment method for slope farmland, as Figure 1As shown, including:

[0035] Step S1, obtain the topographic data of the slope farmland, analyze the topographic data to determine whether the slope farmland contains fish eye bubble.

[0036] Step S2, if it contains fish eye bubble, determine the topographic data corresponding to the fish eye bubble and set it as fish eye bubble topographic data.

[0037] Step S3, drain the accumulated water in the fish eye bubble, and dig a channel according to the fish eye bubble topographic data, and shape the channel.

[0038] Step S4, lay straw pile in the channel, and backfill mature soil on the straw pile.

[0039] As can be understood, the present application proposes an effective treatment method for fish eye bubble problem of slope farmland. As shown, the method mainly includes the following four steps: Figure 1

[0040] I. Obtain the topographic data of the slope farmland. First, through measurement and monitoring, obtain the topographic data of the slope farmland. These data can provide basic information for subsequent analysis.

[0041] II. Analyze the topographic data to determine the existence of fish eye bubble. Analyze the obtained topographic data to determine whether there is fish eye bubble. If fish eye bubble is found, proceed to the next step.

[0042] III. Treat fish eye bubble. For slope farmland with fish eye bubble, the following two sub-steps are needed:

[0043] 1. Determine the topographic data corresponding to the fish eye bubble and set it as fish eye bubble topographic data. This helps to carry out targeted treatment subsequently.

[0044] 2. Drain the accumulated water in the fish eye bubble, and dig a channel according to the fish eye bubble topographic data, and shape the channel. The purpose of this step is to change the topography of the fish eye bubble area, so as to reduce the phenomenon of accumulated water, and lay the foundation for subsequent treatment.

[0045] IV. Fill the channel to improve soil structure. After completing the channel shaping, the following two sub-steps are needed:

[0046] 1. Lay straw pile in the channel. Straw has good water and fertilizer retention effect, which is beneficial to improve soil structure and increase soil fertility.

[0047] 2. Backfill mature soil on the straw pile. Mature soil has good soil fertility and structural stability, which can improve the soil erosion resistance and further improve the soil condition of the fish eye bubble area.

[0048] ​Through the above four steps, the method provided by the present application can effectively treat the fish-eye bubble problem of slope farmland, improve the land utilization rate, and promote the sustainable development of agriculture. In practical application, the treatment measures can be adjusted according to the specific circumstances to achieve better treatment effect.

[0049] The present application determines the shape and size of the trench by analyzing the fish-eye bubble of the slope farmland, and lays straw stacks and mature soil to make it reach the cultivation state. When a rainstorm comes, the water flow will seep into the ground through the straw layer, thereby changing the surface runoff into underground flow, reducing the flow force, and restoring the fish-eye bubble to a good farmland. Through the treatment, the integrity of the farmland is restored, which is beneficial to large mechanical operation and improves the utilization rate of the farmland.

[0050] In some embodiments of the present application, analyzing the topographic data to determine whether the slope farmland contains fish-eye bubbles comprises:

[0051] Generating a three-dimensional topographic map of the slope farmland according to the topographic data, and dividing the three-dimensional topographic map into a plurality of grids.

[0052] Determining each terrace farmland of the slope farmland according to the three-dimensional topographic map.

[0053] Determining the height data of each grid of each terrace farmland, and determining the basic height of each terrace farmland based on the height data.

[0054] Calculating the difference between the height data and the basic height, respectively, and if the difference is greater than a preset difference, determining that the grid of the height data corresponding to the difference is a fish-eye bubble grid.

[0055] Determining whether the slope farmland contains fish-eye bubbles according to the fish-eye bubble grid.

[0056] In this embodiment, when the slope farmland is cultivated, it is generally transformed into terraces to reduce water and soil loss and improve the cultivation value and yield of the land. After building terraces on the slope farmland, the slope can be effectively reduced, the soil moisture content can be increased, and the water loss can be reduced, thereby improving the planting conditions of the land. The present application can determine the number of layers of the slope farmland terraces and determine each terrace farmland by generating a three-dimensional topographic map of the slope farmland. The height data of each grid is the average of all height data in the grid.

[0057] Determining the basic height of each terrace farmland based on the height data, specifically, determining the mode of the height data, and setting the height data corresponding to the mode as the basic height of each terrace farmland. When the difference between the height data and the basic height determines whether it is a fish-eye bubble grid, the greater the difference, the lower the height corresponding to the grid, the deeper the pit formed, and the more likely it is to exist fish-eye bubble.

[0058] In some embodiments of the present application, determining whether the slope farmland contains fish eye bubble according to the fish eye bubble grid comprises:

[0059] Determining whether the fish eye bubble grid is adjacent.

[0060] If the fish eye bubble grid is adjacent, determining the number of adjacent fish eye bubble grids.

[0061] If the number of adjacent fish eye bubble grids is greater than a preset number, determining that the farmland corresponding to the fish eye bubble grid is a fish eye bubble, and the slope farmland contains a fish eye bubble.

[0062] If the number of adjacent fish eye bubble grids is less than a preset number, determining that the farmland corresponding to the fish eye bubble grid is not a fish eye bubble, and the slope farmland does not contain a fish eye bubble.

[0063] In the present embodiment, the fish eye bubble grid has been determined to be a grid with lower terrain than the terrain of each ladder farmland. When the number of such fish eye bubble grids is greater and closely adjacent, it indicates that the range of the fish eye bubble grid is larger. When a certain scale is formed, a fish eye bubble is formed. Therefore, by determining whether the slope farmland contains a fish eye bubble according to the number of adjacent fish eye bubble grids, when the number of adjacent fish eye bubble grids is greater than a preset number, it indicates that the farmland corresponding to the fish eye bubble grid reaches a certain scale, which can be identified as a fish eye bubble.

[0064] In some embodiments of the present application, a trench is dug according to the fish eye bubble terrain data, comprising:

[0065] Determining the characteristic information of the fish eye bubble according to the fish eye bubble terrain data, the characteristic information including width, depth, and farmland position.

[0066] According to the characteristic information, a trench is dug, the trench width is greater than the width of the fish eye bubble, the trench depth is greater than the depth of the fish eye bubble, and the center position of the trench is the center position of the fish eye bubble.

[0067] In the present embodiment, when governing the fish eye bubble of farmland, digging a trench is an effective method. First, determine the position and depth of the trench: according to the size, terrain and soil conditions of the fish eye bubble, determine the position and depth of the trench. Generally, the trench should be arranged along the longitudinal or transverse direction of the farmland, and the depth should be about 30-50 cm deeper than the fish eye bubble. In the process of digging the trench: use excavators or manual digging methods to dig the trench according to the predetermined position and depth. During the digging process, attention should be paid to keep the width and depth of the trench uniform. After the excavation is completed, the soil and debris in the trench should be cleaned in time to ensure the smoothness of the trench.

[0068] In some embodiments of the present application, when shaping the trench, the trench is trimmed to be a square and consistent depth trench.

[0069] It can be understood that the channel is finely shaped, aiming to trim the channel to a shape that is regular and uniform in depth. This innovative method not only improves the efficiency of the channel, but also enhances its carrying capacity and stability.

[0070] First of all, it needs to be clear that the shaping of the channel is not a simple surface finishing, but an optimization of the overall structure of the channel. In this process, through accurate control, the shape of the channel is adjusted to be square and the depth is kept consistent. Such design makes the channel have a significant improvement in carrying capacity.

[0071] Secondly, this shaping process also considers the stability of the channel. In the shaping process, full consideration is given to the material of the channel, the use environment and other factors to ensure that the shaped channel can maintain stable performance in various situations. This design makes the channel better cope with various challenges during use and prolong its service life.

[0072] In addition, the shaping process of the channel fully embodies the concept of environmental protection. In the shaping process, strict compliance with environmental protection regulations is ensured to minimize the impact of the shaping process on the environment. At the same time, the shaped channel can better meet the environmental protection requirements and contribute to China's green development.

[0073] In summary, the channel shaping method proposed in this application optimizes the channel from multiple aspects such as improving carrying capacity, enhancing stability, and focusing on environmental protection.

[0074] In some embodiments of the present application, when the straw pile is laid in the channel, according to the depth of the channel, several layers of straw piles are laid, and each layer of the straw pile is backfilled with mature soil. Each layer of the straw pile is staggered, and every two layers of the straw pile is also staggered.

[0075] In this embodiment, when laying straw piles in the channel, dry and mildewed straw should be selected to avoid using rotten or mildewed straw. And the straw piles are evenly laid in the channel, which can be laid by manual or mechanical method to ensure that the straw piles are in full contact with the soil. During the laying of the straw pile, it should be properly compacted. Among them, whether it is between each layer of straw pile or between every two layers of straw pile, the staggered laying method is adopted, which can effectively prevent water and soil loss. The staggered laying of the straw pile can increase the roughness of the soil, slow down the impact and flow rate of the underground water, thereby reducing the occurrence of water and soil loss. This has an important role in protecting farmland and ecological environment.

[0076] In some embodiments of the present application, the length of the straw pile is 0.8-1.2 meters, the width is 0.5-0.6 meters, and the height is 0.3-0.4 meters.

[0077] In this embodiment, the straw pile can be selected from the straw left after the harvest of crops, such as corn straw, wheat straw, etc. The collected straw is cleaned to remove impurities and dirt. Water washing or manual selection can be used. At the same time, the straw can be cut into small sections. Cutting can be done using a knife or mechanical equipment. After drying, it is compacted and bound into a rectangular straw pile. The size of the straw pile can be adjusted as needed, but it should not be too large or too small. A small or small straw pile cannot stabilize the soil, and a large straw pile is prone to poor air permeability, which can cause the straw pile to ferment and form fish eye bubbles. Therefore, a straw pile of appropriate size should be selected or made.

[0078] In some embodiments of the present application, when backfilling the mature soil on the straw pile, the height of the backfilled mature soil is not less than 0.5 meters.

[0079] In this embodiment, mature soil refers to soil that has been disturbed by human activities, cultivated and fertilized. It has good looseness, air permeability and fertility, and is very suitable for plant growth. The advantages of mature soil include: high organic matter content: mature soil is rich in humus and other organic matter, which helps to improve soil structure, increase soil water retention and permeability; active microbial activity: due to the presence of organic matter, microbial activity in mature soil is more frequent, which helps to cycle and transform soil nutrients, thereby improving soil fertility; good soil structure: mature soil usually has good aggregate structure, which makes the soil loose, easy for root penetration and expansion, and also facilitates the flow of water and air; deep plough layer: the plough layer of mature soil is generally deep, which provides sufficient space for plant roots, conducive to plant growth and development. In contrast to mature soil, raw soil is usually not cultivated by humans, lacks organic matter and microbial activity, and has a tight soil structure that is not conducive to plant growth. To convert raw soil to mature soil, organic matter such as decomposed leaves, animal manure, etc. needs to be added, and a sufficient cultivation and decomposition process needs to be carried out. This process may take a long time, but ultimately the soil will become more fertile and more suitable for plant growth. In agricultural production, maintaining and increasing the quality of mature soil is very important, as it directly affects crop growth and yield. Therefore, farmers and gardeners usually take a series of soil management measures, such as regular plowing, application of organic fertilizers, reasonable crop rotation, etc., to maintain the maturation of the soil. Therefore, when backfilling mature soil, the height of the backfilled mature soil should be appropriate. If the height of the backfilled mature soil is too low, it is not conducive to the growth of crops.

[0080] In some embodiments of the present application, when backfilling mature soil on the straw pile, the mature soil is divided into a compacted layer of mature soil and a loose layer of mature soil, the compacted layer of mature soil being located below the loose layer of mature soil, and the ratio of the height of the compacted layer of mature soil to the height of the loose layer of mature soil being 2:3.

[0081] In this embodiment, by dividing the mature soil into a compacted layer and a loose soil layer, the growth of crops is facilitated. The loose soil layer refers to the layer closest to the ground and is the main place for crop growth. The loose soil layer is usually loose and porous, with frequent dry-wet alternation, large temperature change, good permeability, fast material transformation, and contains more available nutrients. The root system is mainly concentrated in this layer, which generally accounts for the vast majority of the total amount of root system. The compacted layer refers to the layer below the loose soil layer, which is formed by plowing and other farm tools. The soil density of the compacted layer is larger and the porosity is lower, and the setting of the compacted layer can effectively reduce the loss of water, provide more water for the crop root system in the loose soil layer, and ensure the normal growth of crops. In general, the compacted layer and the loose soil layer of the soil are different levels in the cultivated soil profile, and their formation and management are crucial to maintaining the productivity and health of the soil. Through appropriate agricultural management and tillage practices, these soil levels can be optimized to support plant growth and improve crop yield.

[0082] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it, although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand: the specific embodiments of the present application can still be modified or replaced by the equivalent, without departing from the spirit and scope of the present application, any modification or equivalent replacement, which should be covered within the protection scope of the claims of the present application.
