Description

Technical Field

[0001] The invention belongs to the technical field of rice seedling cultivation, and in particular relates to a rice biomass ecological seedling cultivation device. Background Art

[0002] Rice biomass ecological rice seedling cultivation is an innovative rice seedling cultivation technology. It mostly uses plant straw, such as corn straw, wheat straw, rice straw, mushroom residue, etc., which are crushed and fermented, and then mixed with trace elements and organic carriers. These biomass raw materials have a wide range of sources, realizing the reuse of waste and reducing environmental pollution.

[0003] Traditional seedling raising mostly uses plastic seedling trays, while biomass seedling raising uses seedling trays made of degradable plant fiber film or straw biomass to replace plastic seedling trays, solving the white pollution problem caused by plastic seedling trays. Biomass seedling trays are both seedling trays and seedling substrates, with good water retention, heat preservation, air permeability and water permeability, which can make the average temperature of the seedling bed rise faster than that of conventional nutrient soil seedling raising, reduce the number of watering, and facilitate early maturity and increased yield of rice;

[0004] At present, the existing rice biomass ecological seedling raising technology uses biomass seedling raising trays for raising seedlings, but the material characteristics of the biomass seedling raising trays themselves determine that their temperature buffering performance is not as good as some traditional seedling raising facilities. Compared with plastic seedling raising trays with a heat preservation and heat insulation layer design, biomass seedling raising trays cannot well maintain the temperature stability of the internal seedling growth environment when encountering a sharp change in external temperature. In early spring or an environment with a large temperature difference between day and night, the seedlings may suffer from temperature stress, which will affect the effect of raising seedlings. Therefore, it is necessary to use a protective structure to protect the seedling raising and improve the effect of rice biomass seedling raising;

[0005] In order to solve the above problems, this application proposes a rice biomass ecological rice seedling raising device. Summary of the invention

[0047] It can be understood that, firstly, by cooperating with the placing plate 10 of the box body 1 and the isolation frame 9, the biomass seedling raising tray can be used for protecting the seedling raising, and by cooperating with the limiting rod 20 and the groove frame 19 of the sliding frame 22, the placing plate 10 can be adjusted and limited in position in the box body 1, so that rice biomass ecological seedling raising trays of different sizes and heights can be placed in the box body 1, and at the same time, by using the heating frame 15 in cooperation with the refrigeration module 17, the three-way pipe 16, the refrigeration frame 13 and the controller 3, the seedling raising temperature in the box body 1 can be increased or decreased, and by using the temperature sensor 11 in cooperation with the display 2, the temperature in the box body 1 can be sensed, so that the seedling raising temperature in the box body 1 can be conveniently controlled according to the external temperature, and at the same time, by using the water tank 21 in cooperation with the water pump 29 and the humidity sensor 23, the humidity of the seedling raising in the box body 1 can be sensed, and the liquid can be transferred to the box body 1, so that the humidity of the seedling raising in the box body 1 can be controlled, and the effect of biomass rice seedling raising can be further improved.

[0048] A specific application of this embodiment is: when in use, first, the humidity sensor 23, the water pump 29, the display 2, the temperature sensor 11, the heating frame 15, the refrigeration module 17 and the controller 3 are connected to the power supply, and the heating frame 15, the water pump 29 and the refrigeration module 17 are connected to the controller 3 through the wire, and the temperature sensor 11 and the humidity sensor 23 are connected to the display 2, and then the box body 1 is moved to a suitable use position by the wheel frame 5 in cooperation with the rotating wheel 6, and the protective cover 27 is removed from the liquid adding pipe 28, and a suitable liquid is added to the water tank 21 through the liquid adding pipe 28. When the water tank 21 is added to a suitable amount, the protective cover 27 is installed on the liquid adding pipe 28 again, and the opening and closing door 7 is opened at the same time, and the water tank 21 is cooled and cooled according to the temperature of the rice. The height of the biomass seedling raising tray is adjusted by pulling the limit rod 20 out of the slot frame 19 and the sliding frame 22, and sliding the sliding frame 22 up and down in the slot frame 19. At the same time, the sliding of the sliding frame 22 drives the two sets of placement plates 10 to adjust the distance between them. When the placement plates 10 have finished adjusting the distance, the limit rod 20 is passed through the slot frame 19 and the sliding frame 22 again, so that the limit rod 20 limits the sliding frame 22 and the placement plate 10 to the slot frame 19, and the rice biomass seedling raising tray is placed on the placement plate 10 for raising seedlings. When the placement is completed, the temperature in the box body 1 is sensed by the temperature sensor 11, and the temperature signal is transmitted to the display 2 through the wire for display. The staff uses the display of the display 2 and the height of the outside temperature to control the temperature of the rice biomass seedling raising tray through the controller 3. The heating rack 15 and the refrigeration module 17 are turned on or off. When the display 2 shows that the temperature in the box 1 is low, the heating rack 15 is turned on, and the temperature in the box 1 is increased by turning on the heating rack 15. When the temperature reaches a suitable temperature range for raising seedlings, the heating rack 15 is turned off. When the display 2 shows that the temperature in the box 1 is high, the refrigeration module 17 is turned on, and the air is cooled by turning on the refrigeration module 17. At the same time, the air is transferred to the refrigeration rack 13 through the three-way pipe 16, so that the refrigeration rack 13 reduces the temperature in the box 1. When the display 2 shows that the temperature in the box 1 has dropped to a suitable range, the refrigeration module 17 is turned off, and the rice biomass seedling raising tray in the box 1 is observed through the perspective plate 8. Then the humidity sensor 23 is turned on to cool the box 1. The humidity of the rice biomass seedling raising tray in the box 1 is sensed, and the humidity signal is transmitted to the display 2 through the wire for display. When the display 2 shows that the humidity in the box 1 is high, the opening and closing door 7 is opened again to allow the air in the box 1 to be emitted to the outside and circulate with the external air, thereby reducing the humidity of the rice biomass seedling raising tray in the box 1. When the humidity drops, the opening and closing door 7 is closed. When the display 2 shows that the humidity in the box 1 is low, the controller 3 turns on the water pump 29 through the wire. At the same time, the water pump 29 is turned on to transfer the liquid in the water tank 21 to the connecting pipe 24, and the liquid is transferred to the atomizing plate 25 through the connecting pipe 24. At the same time, the continuous transmission of the water pump 29 causes the atomizing plate 25 to spray the liquid into the box 1.This can increase the humidity of the rice biomass seedling raising tray in the box 1, and further improve the effect of rice biomass ecological seedling raising.
