Description

TECHNICAL FIELD

[0001] The utility model relates to rice planting cultivation device technical field, specifically related to a rice planting cultivation device with adjusting function. BACKGROUND

[0002] Rice planting cultivation is an agricultural production activity covering the whole process from seed selection, seedling, transplanting to field management, aiming to promote the healthy growth of rice and improve yield and quality through scientific methods and management measures.

[0003] Rice planting breeding and cultivation can screen out healthy and full seeds and remove inferior seeds, thereby significantly improving the germination rate of seeds, and in the seedling process, through scientific management such as suitable temperature, humidity, light and nutrient supply, strong seedlings can be cultivated, laying a good foundation for subsequent field growth. The strong seedlings bred by breeding and cultivation grow more balanced and consistent after being transplanted to the field, which is conducive to the unified management of the field and reduces the problem of uneven growth caused by individual differences. At the same time, in the breeding process, varieties with strong disease and pest resistance can be selected for cultivation, so that rice is less disturbed by diseases and pests during growth, reduces the use of pesticides, and improves yield and quality.

[0004] The closed artificial light seedling system is a relatively advanced high-efficiency seedling production system, which uses light-tight thermal insulation materials as the enclosure structure to limit the exchange of air, water and heat between the inside and outside of the system as much as possible, and uses artificial light sources to provide light for plant growth. The environment in the system is almost not affected by external environmental factors, and the temperature, humidity, carbon dioxide concentration, air flow speed and light in the system can be completely automatically controlled according to the requirements of plants and the ideal mode set. Since the system is less affected by natural conditions, crop production is planned, production speed is fast, cycle is short, automation degree is high, there is no pollution, and the multi-level three-dimensional cultivation mode can improve the land utilization rate per unit area, so it has become the focus of research in recent years. At present, the closed artificial light seedling system mainly meets the photosynthesis of rice seeds or seedlings by artificially controlling the light intensity in the closed cultivation box, but the artificial control of light energy consumption is large, which reduces the economic benefit.

[0043] During the cultivation process of the rice seeds and rice seedlings in the seed cultivating assembly 5 and the seedling cultivating assembly 6 respectively, the nutrient solution is sprayed to the seed cultivating assembly 5 and the seedling cultivating assembly 6 through the nutrient solution supply assembly 7 according to the cultivation requirements; and during the continuous cultivation process, the light intensity, temperature, humidity, and carbon dioxide concentration in the first culture cavity 2 and the second culture cavity 3 are respectively adjusted by the intelligent light-adjusting glass, the temperature control assembly 8, the humidity control assembly 9, and the carbon dioxide control assembly 10, so that the rice seeds and rice seedlings are respectively in the most suitable growth environment and do not interfere with each other.

[0044] In this embodiment, the automatic control device 11 is installed on the outer wall of the incubator body 1, and the automatic control device 11 is electrically connected with the intelligent light control glass, the nutrient solution supply assembly 7, the temperature control assembly 8, the humidity control assembly 9 and the carbon dioxide control assembly 10.

The side wall of the seed culture tray 12 has a leakage port 13, the distance between the leakage port 13 and the bottom of the seed culture tray 12 is 0.3cm to 0.6cm, and the leakage port 13 is in communication with the nutrient solution supply assembly 7.

[0048] In this embodiment, the seed culture tray 12 is made of metal or plastic, which is mainly used for containing rice seeds and ensuring the water needed for the germination of rice seeds.

[0049] During the seed cultivation process, the automatic control device 11 controls the nutrient solution supply assembly 7 to spray nutrient solution into the seed cultivation tray 12 at regular intervals. Since the seed cultivation tray 12 has a leakage opening 13, and the distance between the leakage opening 13 and the bottom of the seed cultivation tray 12 is 0.3-0.6 cm, the seed cultivation tray 12 has a certain height of nutrient solution. Rice seed cultivation usually requires absorbing 25%-40% of its own weight of water, and the nutrient solution at the bottom of the seed cultivation tray 12 is beneficial to the rapid absorption of water and nutrients by the seed and the rapid germination and rooting of the seed, thereby improving the seed germination efficiency. At the same time, the leakage opening 13 is used to discharge excess nutrient solution and flow into the nutrient solution supply assembly 7 again, thereby avoiding excessive depth of the nutrient solution and affecting the rice seed germination efficiency.

[0050] In this embodiment, the seedling cultivation assembly 6 includes a seedling culture box 14 installed in the second culture cavity 3 through a support block. The seedling culture box 14 is filled with culture medium, and the bottom of the seedling culture box 14 has a water leakage hole.

[0051] In this scheme, the culture box 14 is filled with a certain height of culture medium, which can use a mixture of sawdust and nutrient soil to improve the moisture retention efficiency, and then the rice seedlings are transplanted on the culture medium.

[0052] During the rice seedling cultivation process, the automatic control device 11 controls the nutrient solution supply assembly 7 to spray nutrient solution into the culture box 14 to keep the culture medium wet enough.

[0056] As shown in Figure 2 , Figure 3 In the embodiment, the supply box 15 is also connected with the batching box 23, the batching box 23 is located outside the culture box body 1, a plurality of automatic metering assemblies 24 are installed on the batching box 23, and the automatic metering assemblies 24 are electrically connected with the automatic control device 11.

[0057] In the scheme, after the nutrient substrate sensor 22 transmits the concentration information of various nutrient substrates in the supply box 15 to the automatic control device 11, the automatic control device 11 controls the automatic metering assembly 24 to automatically match the nutrient solution with a suitable concentration, such as nitrogen, phosphorus, potassium and silicon.

[0058] The nutrient solution matched in the batching box 23 is mixed with the nutrient solution in the supply box 15 to form a nutrient solution with a suitable concentration, and then is introduced into the supply box 15 to mix and match with the original nutrient solution to form a concentration suitable for rice seed cultivation and seedling cultivation, and different nutrient substrate concentrations are matched according to different culture periods, and then are sprayed into the seed culture plate 5 and the seedling culture box 14 through the nutrient solution supply assembly 7.

[0060] In the scheme, the temperature sensor 25 monitors the temperature in the first culture cavity 2 and the second culture cavity 3 in real time, and the temperature sensor 25 can adopt the MG-EM50 series sensor.

[0061] When the temperature is lower than the set suitable temperature range, the temperature sensor 25 transmits a low temperature signal to the automatic control device 11, and the automatic control device 11 controls the heating sheet 26 to work, so as to increase the temperature in the first culture cavity 2 and the second culture cavity 3. When the temperature is higher than the set suitable temperature range, the temperature sensor 25 transmits a high temperature signal to the automatic control device 11, and the automatic control device 11 controls the air exchange fan 29 to work. The heating sheet 26 can be a JRB-250 type heating sheet.

[0062] In this embodiment, the humidity control assembly 9 comprises a humidity sensor 27, a humidifier 28 and an air exchange fan 29. The humidity sensor 27 and the humidifier 28 are installed in the first culture cavity 2 and the second culture cavity 3, and the air exchange fan 29 is installed on the side wall of the first culture cavity 2 and the second culture cavity 3. The humidity sensor 27, the humidifier 28 and the air exchange fan 29 are electrically connected with the automatic control device 11.

[0063] In this scheme, the humidity sensor 27 monitors the humidity in the first culture cavity 2 and the second culture cavity 3 in real time. The humidity sensor 27 can be a sensor of the TEROS series.

[0064] When the humidity is lower than the set suitable humidity range, the humidity sensor 27 transmits a low humidity signal to the automatic control device 11, and the automatic control device 11 controls the humidifier 28 to start after receiving the signal, so as to increase the humidity in the first culture cavity 2 and the second culture cavity 3. When the humidity is higher than the set suitable humidity range, the humidity sensor 27 transmits a high humidity signal to the automatic control device 11, and the automatic control device 11 controls the air exchange fan 29 to start after receiving the signal, so as to decrease the humidity in the first culture cavity 2 and the second culture cavity 3.

[0065] In this embodiment, the carbon dioxide control assembly 10 comprises a carbon dioxide sensor 30 and a carbon dioxide cylinder 31.

[0067] When the carbon dioxide concentration is lower than or higher than the set suitable concentration range, the carbon dioxide sensor 30 transmits a signal to the automatic control device 11. After receiving the signal, the automatic control device 11 controls the opening or closing of the third electromagnetic valve 34 and the fourth electromagnetic valve 35 to adjust the amount of carbon dioxide delivered by the carbon dioxide cylinder 31 into the cavity. For example, when the carbon dioxide concentration is too low, the third electromagnetic valve 34 and the fourth electromagnetic valve 35 are opened, and the carbon dioxide cylinder 31 delivers carbon dioxide into the cavity through the first gas delivery pipe 32 and the second gas delivery pipe 33; when the carbon dioxide concentration is too high, the third electromagnetic valve 34 and the fourth electromagnetic valve 35 are closed, and the delivery of carbon dioxide is stopped, so that the suitable carbon dioxide concentration environment is maintained.

[0068] In the embodiment, the first culture cavity 2 and the second culture cavity 3 are both provided with LED daylight lamps 36, and the LED daylight lamps 36 are electrically connected to the automatic control device 11.
