Embodiment 1

[0039] Example 1 Seedling-free tray straw degradable matrix block for dry seedling raising of rice

[0040] Seedling-free tray straw degradable matrix block profile prepared in this example is as follows figure 1 As shown, the matrix block matrix 1 is included, and the matrix block matrix 1 is surrounded by a frame 2 protruding from the surface of the matrix block matrix; The connected part is the hole wall 4, and the flat bottom of the cavity 3 is the hole valley 5; the lower surface of the substrate block 1 is provided with a number of square protrusions 6 arranged vertically and horizontally, and the adjacent protrusions are arranged vertically or horizontally to form a "π" shape. The air channel 7; the recess 3 matches the shape of the protrusion 6.

[0041] For the preparation method of the material of the matrix block in this embodiment, refer to the "multi-layer straw matrix block" prepared in Example 1 of Chinese patent "110476774A" (invention name: a multi-layer rice...

Embodiment 2

[0047] Example 2 Design and optimization of the frame structure of the degradable matrix block of the seedling-free tray

[0048] The content design of the seedling-free tray straw degradable matrix block module of this application is the same as that of Example 1, the difference lies in the angle θ between the frame and the lower surface plane of the matrix block matrix, and the monitoring of the leakage rate of rice seeds in the sowing process of the matrix block in the assembly line, etc. Phenomenon.

[0052] Control group CK-B: θ=175°;

[0053] Control group CK-C: no frame design, other same as test group S-A.

[0054] Statistics on the probability of rice seed spreading: put 20 straw degradable matrix blocks into the fully automatic rice seedling raising and sowing line in turn. For the sowing method, refer to the enterprise standard of Kubota Agricultural Machinery ...

Embodiment 3

[0058] Embodiment 3 stereotyped layer film formula and screening optimization

[0059] According to the structural design results of embodiment 2, it is found that the matrix block frame can effectively prevent the leakage phenomenon of rice seeds in the assembly line seedling cultivation and sowing process. However, in the later stage of seedling raising, due to the water absorption and hygroscopic characteristics of the frame material, it is easy to cause its collapse and affect the subsequent planting of seedlings. Therefore, on the basis of this structure, this embodiment adopts a synthetic polymer to shape the frame.

[0060] The cross-sectional structure of the rice seedling-free tray straw degradable matrix block obtained in this example is as follows: figure 2 shown.

[0061] The matrix block includes a base body 1, and the base body 1 is provided with a frame 2 protruding from the surface of the base body 1; The square protrusion 6 corresponding to the hole 3, the ...

Abstract

The application discloses a seedling-free straw degradable substrate block for dry rice seedling raising, comprising a substrate and a frame around the substrate that protrudes from the surface of the substrate; The lower surface is provided with a square protrusion corresponding to the cavity, and the shape of the cavity is matched with that of the protrusion; A "π"-shaped air channel is formed; the outer frame and the lower surface of the substrate are sprayed with a shaping layer film; the original frame structure of the substrate block of the present application can prevent the continuous sowing of rice seeds from spilling and the adhesion of rice seedling roots, and improve the volume of the substrate block. Blanket efficiency; the "π"-shaped airway structure can ensure the oxygen supply to the bottom of the substrate after the rice seeds in the concave root, and promote the formation of a gas-liquid-solid interface with the lower surface bulge, which has the functions of water retention and ventilation; the substrate block can effectively promote the rice Specialization, mechanization and scale of seedling raising and machine transplanting cultivation.

Description

technical field [0001] The invention relates to the related technical field of agricultural rice seedling raising matrix carrier and agricultural machinery for rice seedling raising, in particular to a seedling-free tray straw degradable matrix block for dry rice seedling raising. Background technique [0002] my country is the largest rice producer and consumer in the world, and more than 60% of the population takes rice as the main food. So far, my country's rice planting area has exceeded 20% of the world's total planting area, and the annual total grain output accounts for 1 / 3 of the global total grain output. With the transformation of planting patterns, rice planting is gradually developing towards standardization and scale. To achieve sustainable development of the rice industry, yield and quality are equally important. Seedling raising is the first step in rice high-yield cultivation technology, and is the basis for realizing high-yield and high-quality rice. [00...
