Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a method for planting rice floating on the water surface of a coal mining subsidence area based on non-woven fabric. Background Art

[0002] With the exploitation of resources such as coal, large areas of subsidence have appeared in many regions. If the water surfaces formed in these subsidence areas are not utilized, it will not only cause a waste of land resources, but also may bring a series of environmental problems. At the same time, the traditional rice planting method has high requirements for land and faces challenges in water resource management and soil quality. Therefore, it is of great practical significance to develop a rice planting method suitable for the water surface of the subsidence area. In particular, solving the problem of excessive nitrogen fertilizer application in rice planting on the water surface of the subsidence area provides technical support for the high-yield and high-quality cultivation technology of rice in the traditional coal mining subsidence area.

[0003] In addition, most of the existing water surface planting is achieved by placing a planting cup on a float, allowing the float to float in the water, and installing ropes on both sides of the float to position the float. However, when encountering strong winds, the float is prone to shaking. Summary of the invention

[0004] The purpose of the present invention is to provide a method for planting floating rice on the water surface of coal mining subsidence areas based on non-woven fabrics, aiming to overcome the defects of the prior art and solve the problems of excessive application of nitrogen fertilizer in rice planting on the water surface and the floating board shaking easily in windy weather.

[0005] To this end, the present invention proposes a method for planting floating rice on the water surface of a coal mining subsidence area based on a non-woven fabric, comprising the following method steps: S1. Select a planting cup, construct a non-woven planting method in the planting cup, and at the same time establish a corresponding track in the subsidence area; S2. Based on the non-woven fabric type, the selected planting cups are classified and arranged according to different nitrogen addition environments; S3, adding soil with different nitrogen application amounts to the various planting cups under different nitrogen addition environments in S2, and planting rice with different planting densities at the same time; S4, based on the above S3, placing the planted planting cups on a pre-made boat-shaped floating board, wherein a roller is provided on the boat-shaped floating board close to the track; S5, connecting the rollers and the track, and pushing the floating plate so that the floating plate can move on the track, so as to enter the upper part of the river channel in the subsidence area; S6. After the rice in the planting cups is planted to maturity, the yield of each pot of rice is calculated.

[0006] As a preferred embodiment of the present invention, the specific steps of constructing a non-woven fabric cultivation method in the planting cup based on the above S1 include: First, a non-woven fabric is pasted on the bottom of the inner cavity of the planting cup, so that the non-woven fabric can ensure that water is continuously supplied to the planting matrix through the water inlet at the bottom of the planting cup, and at the same time ensure that the planting matrix in the planting cup will not be lost; Secondly, ceramsite is placed on top of the non-woven fabric attached to the planting cup. The ceramsite can absorb nutrients such as nitrogen and phosphorus in the matrix, thereby maintaining the fertility of the matrix. At the same time, there are gaps between the ceramsite, which can increase air circulation and make the rice breathe better; Then place the substrate on top of the expanded clay. Because the substrate contains various organic and inorganic components, it can provide rich nutrients for plant growth and has a good water retention effect. Therefore, it makes up for the relatively limited water retention capacity of expanded clay when used alone to a certain extent, which is beneficial to the survival of plants in drought periods.

[0007] As a preferred embodiment of the present invention, the specific method steps for establishing the corresponding track in the subsidence area based on the above S1 include: the staff selects the subsidence area, and builds the track above the subsidence area, that is, above the river, and both ends of each track are located at the bank of the subsidence area, and each track is provided with positioning piles at both ends.

[0008] As a preferred embodiment of the present invention, the specific method steps for placing different nitrogen additions in the planting cups based on the above S2 include: selecting multiple planting cups, and classifying the planting cups: Planting cups: Examples: A1, A2, A3, A4; B1, B2, B3, B4; C1, C2, C3, C4 and D1, D2, D3, D4, etc.; among which Class A is no nitrogen fertilizer; Class B is N1 nitrogen fertilizer; Class C is N2 nitrogen fertilizer; Class D is N3 nitrogen fertilizer.

[0009] As a preferred embodiment of the present invention, based on the above S3, soil with different nitrogen application amounts is added to a plurality of planting cups under different nitrogen addition environments, and the specific method steps of planting rice with different planting densities at the same time include: According to the above classification, soils with different nitrogen application amounts and rice with different planting densities were added to A, B, C, D, etc.; for example: A1, soil without nitrogen application and one rice plant were added; A2, soil without nitrogen application and two rice plants were added; A3, soil without nitrogen application and three rice plants were added; A4, soil without nitrogen application and four rice plants were added; B1, soil with nitrogen application amount of N1 and one rice plant were added; B2, soil with nitrogen application amount of N1 and two rice plants were added; B3, soil with nitrogen application amount of N1 and three rice plants were added; B4, C1, soil with nitrogen application amount of N2 and one rice plant; C2, soil with nitrogen application amount of N2 and two rice plants; C3, soil with nitrogen application amount of N2 and three rice plants; C4, soil with nitrogen application amount of N2 and four rice plants; D1, soil with nitrogen application amount of N3 and one rice plant; D2, soil with nitrogen application amount of N3 and two rice plants; D3, soil with nitrogen application amount of N3 and three rice plants; D4, soil with nitrogen application amount of N3 and four rice plants, etc.

[0010] As a preferred embodiment of the present invention, based on the above S4, the planted planting cups are placed on a pre-made boat-shaped floating board, wherein the boat-shaped floating board close to the track side is provided with rollers. The specific method steps include: the staff place the planted planting cups on a plurality of boat-shaped floating boards connected into a strip structure, and connecting parts are installed on one side of the boat-shaped floating boards at both ends, and each of the connecting parts is rotatably installed with a roller on the other end, and each of the rollers is slidably arranged in the inner cavity of the track.

[0011] As a preferred embodiment of the present invention, based on the above S5, the specific method steps of pushing the floating plate so that the placed floating plate can move on the track to enter the river channel above the subsidence area include: the staff pushes the placed boat-shaped floating plate so that the boat-shaped floating plate can move with the assistance of rollers and tracks, so that it is located above the river channel of the subsidence area.

[0012] As a preferred embodiment of the present invention, a specific calculation method for calculating the yield of each pot of rice after the rice in the planting cup in S6 is planted to maturity includes: selecting mature products of the same type, such as A1, B1, C1, and D1, and calculating the rice yield index according to the number of ears, number of grains per ear, thousand-grain weight, and fruit setting rate in each pot, and measuring the protein content, amylose content, gel consistency and alkali consumption value of the rice by an infrared analyzer DA-7250, to determine the rice yield that is highest when different nitrogen additions are made under the same density.

[0013] Compared with the prior art, the present invention has the following beneficial effects: According to the present invention, the staff selects a subsidence area and builds a track above the subsidence area, and then installs and fixes it at both ends through positioning piles. The planted planting cups are respectively placed on a plurality of boat-shaped floating plates, wherein a connecting piece is installed on one side of the boat-shaped floating plate, and a roller is rotatably installed on the other end of each connecting piece. Therefore, the staff can put the rollers into the inner cavity of the track respectively, and then push the boat-shaped floating plate to move above the river channel of the subsidence area, thereby reducing the possibility of the floating plate shaking even in windy weather.

[0014] At the same time, multiple planting cups are selected and classified, and no nitrogen, N1, N2 and N3 are added to different categories.

At this time, the staff will select the same mature products when the rice is mature. At this time, the rice yield index is calculated according to the number of ears, number of grains per ear, thousand-grain weight, and fruit setting rate in each pot. The protein content, amylose content, gel consistency and alkali elimination value of the rice are measured by infrared analyzer DA-7250 to determine the rice yield with the highest nitrogen addition under the same conditions. The precise application of nitrogen fertilizer for rice planting on the water surface of the subsidence area is realized, and technical support is provided for the high-yield and high-quality cultivation technology of rice in coal mining subsidence areas.

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] like Figures 1 to 6 As shown, a method for planting rice floating on the water surface of a coal mining subsidence area based on non-woven fabrics includes the following steps: S1. Select a planting cup, construct a non-woven planting method in the planting cup, and at the same time establish a corresponding track in the subsidence area; S2. Based on the non-woven fabric type, the selected planting cups are classified and arranged according to different nitrogen addition environments; S3, adding soil with different nitrogen application amounts to the various planting cups under different nitrogen addition environments in S2, and planting rice with different planting densities at the same time; S4, based on the above S3, placing the planted planting cups on a pre-made boat-shaped floating board, wherein a roller is provided on the boat-shaped floating board close to the track; S5, connecting the rollers and the track, and pushing the floating plate so that the floating plate can move on the track, so as to enter the upper part of the river channel in the subsidence area; S6. After the rice in the planting cups is planted to maturity, the yield of each pot of rice is calculated.

[0019] like Figures 1 to 3 As shown, in a specific embodiment, the specific steps of constructing a non-woven fabric cultivation method in a planting cup based on the above S1 include: First, a non-woven fabric is pasted on the bottom of the inner cavity of the planting cup, so that the non-woven fabric can ensure that water is continuously supplied to the planting matrix through the water inlet at the bottom of the planting cup, and at the same time ensure that the planting matrix in the planting cup will not be lost; Secondly, ceramsite is placed on top of the non-woven fabric attached to the planting cup. The ceramsite can absorb nutrients such as nitrogen and phosphorus in the matrix, thereby maintaining the fertility of the matrix. At the same time, there are gaps between the ceramsite, which can increase air circulation and make the rice breathe better; Then place the substrate on top of the expanded clay. Because the substrate contains various organic and inorganic components, it can provide rich nutrients for plant growth and has a good water retention effect. Therefore, it makes up for the relatively limited water retention capacity of expanded clay when used alone to a certain extent, which is beneficial to the survival of plants in drought periods.

[0020] Furthermore, based on the above S1, the specific method steps for establishing the corresponding track in the subsidence area include: the staff selects the subsidence area, and builds the track 3 above the subsidence area, that is, above the river, and both ends of each track 3 are located at the bank of the subsidence area, and each track 3 is provided with positioning piles 2 at both ends.

[0021] Furthermore, based on the above S2, the specific method steps for placing different nitrogen additions in the planting cups include: selecting multiple planting cups, and classifying the planting cups: Planting cups: Examples: A1, A2, A3, A4; B1, B2, B3, B4; C1, C2, C3, C4 and D1, D2, D3, D4, etc.; among which Class A is no nitrogen application; Class B is N1; Class C is N2; Class D is N3, etc.

[0022] Furthermore, based on the above S3, soil with different nitrogen application amounts is added to the various planting cups under different nitrogen addition environments, and the specific method steps for planting rice with different planting densities at the same time include: According to the above classification, soils with different nitrogen application amounts and rice with different planting densities were added to A, B, C, D, etc.; for example: A1, soil without nitrogen application and one rice plant were added; A2, soil without nitrogen application and two rice plants were added; A3, soil without nitrogen application and three rice plants were added; A4, soil without nitrogen application and four rice plants were added; B1, soil with nitrogen application amount of N1 and one rice plant were added; B2, soil with nitrogen application amount of N1 and two rice plants were added; B3, soil with nitrogen application amount of N1 and three rice plants were added; B4, C1, soil with nitrogen application amount of N2 and one rice plant; C2, soil with nitrogen application amount of N2 and two rice plants; C3, soil with nitrogen application amount of N2 and three rice plants; C4, soil with nitrogen application amount of N2 and four rice plants; D1, soil with nitrogen application amount of N3 and one rice plant; D2, soil with nitrogen application amount of N3 and two rice plants; D3, soil with nitrogen application amount of N3 and three rice plants; D4, soil with nitrogen application amount of N3 and four rice plants, etc.

[0023] Furthermore, based on the above S4, the specific method steps of placing the planted planting cups on the pre-made boat-shaped floating board, wherein the boat-shaped floating board close to the track side is provided with a roller include: the staff places the planted planting cups on multiple boat-shaped floating boards respectively, wherein a positive pole magnet 5 or a negative pole magnet 6 is also provided between each boat-shaped floating board, and two adjacent boat-shaped floating boards are attracted to each other by the positive pole magnet 5 and the negative pole magnet 6, so that the multiple boat-shaped floating boards are connected into a strip-shaped boat-shaped floating board assembly, and at the same time, a connecting piece 1 is installed on the outer side of the boat-shaped floating board located at both ends of the same boat-shaped floating board assembly, and the other end of the connecting piece 1 is rotatably installed with a roller 4, and each of the rollers 4 is slidably arranged in the inner cavity of the track 3.

[0024] Furthermore, based on the above S5, the specific method steps of pushing the floating plate so that the placed floating plate can move on the track and enter the river channel above the subsidence area include: the staff pushes the placed boat-shaped floating plate so that the boat-shaped floating plate can move with the assistance of rollers 4 and tracks 3, so that it is located above the river channel of the subsidence area.

[0025] Furthermore, based on the fact that the rice in the planting cup in S6 is planted to maturity, the specific calculation method for calculating the yield of each pot of rice includes: selecting mature products of the same type, such as A1, B1, C1, and D1, and calculating the rice yield index according to the number of ears, number of grains per ear, thousand-grain weight, and fruit setting rate in each pot, and using the infrared analyzer DA-7250 to measure the protein content, amylose content, gel consistency, and alkali consumption value of the rice, and determining the rice with the highest yield when different nitrogen additions are added under the same planting density, thereby achieving precise application of nitrogen fertilizer for surface rice cultivation.

[0026] The implementation principle of the non-woven fabric-based method for planting rice on the surface of submerged water is as follows: First, non-woven fabric is pasted on the bottom of the inner cavity of the planting cup, so that the non-woven fabric can ensure that water is continuously supplied to the planting matrix through the water inlet at the bottom of the planting cup, and at the same time ensure that the planting matrix in the planting cup will not be lost. Secondly, ceramsite is placed on the non-woven fabric pasted on the planting cup. Ceramsite can absorb nutrients such as nitrogen and phosphorus in the matrix, thereby maintaining the fertility of the matrix. At the same time, there are gaps between the ceramsite, so it can increase the circulation of air and make the rice breathe well. Then place the matrix on top of the ceramsite, because the matrix contains various organic and inorganic components, it can provide rich nutrition for plant growth and has a good water retention effect. Therefore, it makes up for the relatively limited water retention capacity of ceramsite when used alone to a certain extent, which is beneficial to the survival of plants in drought periods.

[0027] The staff selected a subsidence area, and then built a track 3 above the subsidence area, that is, above the river, and the two ends of the track 3 were respectively located at the banks of the subsidence area. Therefore, the two ends of the track 3 located above the subsidence area can be installed and fixed by positioning piles 2; at the same time, multiple planting cups were selected, and the planting cups were classified, and no nitrogen, N1, N2 and N3 were put into different categories respectively, and the same soil was added to the corresponding numbers in different categories and the same amount of rice was planted.

[0028] At this time, the staff will place the planted planting cups on a plurality of boat-shaped floating plates connected in a strip structure, wherein a connector 1 is installed on one side of the boat-shaped floating plates at both ends, and a roller 4 is rotatably installed on the other end of each connector 1, so that the staff can put the roller 4 into the inner cavity of the track 3 respectively, and then push the boat-shaped floating plate to move above the river channel in the trapped area.

[0029] When the rice is mature, similar mature products are selected. The rice yield indicators are calculated based on the number of ears, number of grains per ear, 1000-grain weight, and fruit setting rate in each pot. The protein content, amylose content, gel consistency, and alkali consumption value of the rice are measured using an infrared analyzer, DA-7250, to determine the rice yield that is highest when different nitrogen additions are made under the same planting density.
