Description

Technical Field

[0001] The present invention relates to the technical field of poplar branch cultivation devices, and particularly to a temperature control device that promotes the rooting of female poplar branches while inhibiting flowering. Background Art

[0002] There are usually two methods for artificial hybridization of poplars: one is artificial hybridization on large outdoor trees; the other, and most commonly used method, is artificial hybridization indoors after cutting the female parent flower branches. The female and male flower branches are separately collected and hydroponically cultured indoors. After collecting the male pollen, pollination is carried out after waiting for the female flowers to germinate. Finally, the seeds are collected and sown to obtain hybrid progeny seedlings. The specific procedure for indoor artificial hybridization is as follows:

[0003] 1. Collect male flower branches for hydroponics and collect male pollen. Generally, male pollen is collected slightly earlier than the opening of female flowers to avoid timely pollination when the female flowers are most active after blooming.

[0004] 2. Collect female flower branches for hydroponics. After the female flower branches bloom, use the collected male pollen to pollinate the female flowers. However, the following problems often occur during the hydroponics of female flower branches:

[0005] ① The flowering time of female flower branches is earlier than the rooting time at the bottom of the branches, which greatly weakens the ability of the roots to absorb nutrients. Relying solely on the nutrients stored in the branches themselves will result in insufficient nutrient supply, insufficient activity of female pollen, a decrease in the fruiting rate after pollination, and insufficient seed yield and viability.

[0006] ② Hydroponics often leads to microbial infection and excessive mucus secretion in the part immersed in water (the cut base of the branches), which easily causes root rot and hypoxia, affects root formation, and thus affects the absorption and transportation of water and some nutrients, hindering flower development and seed maturation. This requires continuous manual water change and cleaning of the base, which is very likely to waste a large amount of manpower, material resources, and time.

[0007] Therefore, a temperature control device that promotes the rooting of female poplar branches while inhibiting flowering is proposed to solve the above problems. Summary of the Invention

[0034] In this device, the insulation chamber 1 is used to cultivate female poplar flower branches, and the constant temperature air conditioner 46 is used to adjust the temperature in the insulation chamber 1 so that the temperature is always within a constant range. In this embodiment, to inhibit the flowering of the female poplar flower branch 12, the temperature of the insulation chamber 1 is kept constant at 3°C. The sealed door 2 facilitates the entry of scientific research personnel into the insulation chamber 1 and also helps to maintain a constant temperature in the insulation chamber 1; the water source tank 3 is used to hold water for the female poplar flower branch 12, the first water pump 4 pumps the water in the water source tank 3 into the water storage chamber 8, the water level sensor 9 is used to measure the water level in the water storage chamber 8, the water volume adjusting component is used to adjust the water in the planting area 10, the water volume adjusting component can send the water in the water storage chamber 8 into the planting area 10 for the growth of the female poplar flower branch 12, and at the same time, it can also send the water in the planting area 10 back to the water storage chamber 8 to prevent excessive water in the planting area 10 from affecting the growth of the female poplar flower branch 12. The water temperature adjusting component is used to adjust the temperature in the water storage chamber 8 to prevent the water temperature from being too low and affecting the female poplar flower branch 12. The water temperature in the water storage chamber 8 is within the range of 23 - 25°C. The air temperature adjusting component is used to adjust the temperature in the planting area 10, which is beneficial to the rapid rooting of the female poplar flower branch 12. In this embodiment, the temperature in the planting area 10 is between 22°C and 26°C. The top cover 11 is used to cover the planting area 10 to prevent the temperature in the planting area 10 from dissipating too quickly. The net plate 6 facilitates the passage of water and at the same time facilitates the passage of air flow. When watering the female poplar flower branch 12, it should be watered thoroughly at one time, and then all the water in the planting area 10 is drained through the water volume adjusting component. After the water is drained, the air temperature adjusting component is used to ventilate the planting area 10.

[0035] For a further optimized solution, the planting container mechanism includes a planting cup cylinder 13 and an annular expansion groove 14. Both the planting cup cylinder 13 and the annular expansion groove 14 are filled with planting substrate.

When the female poplar branches 12 grow, they will first take root in the planting cup cylinder 13. As the female poplar branches 12 grow, the root system will continuously expand. There are many water-permeable holes on the planting cup cylinder 13 and the annular expansion groove 14. The water-permeable holes not only facilitate the outflow of water but also facilitate the outward growth of the root system. After the root system grows, it will grow towards the adjacent annular expansion groove 14. After opening the upper cover 11, strong light can be projected into the gap, and the growth of the root system of the female poplar branches 12 can be observed through the gap. In this way, the size of the root system of the female poplar branches 12 can be observed without stripping the planting substrate.

[0040] The heater 22 is used to heat the water in the water storage chamber 8. The first temperature sensor 23 is used to measure the temperature in the water storage chamber 8. If the water temperature in the water storage chamber 8 exceeds a fixed range, the water in the water storage chamber 8 is sent to the water source tank 3 through the third water pipe 25 by the fourth water pump 24, and then the water in the water source tank 3 is pumped into the water storage chamber 8 by the first water pump 4 to reduce the water temperature through circulation.

[0041] For a further optimized solution, a number of connecting rods 29 are fixedly connected below the partition 7. A first mounting plate 30 is fixedly connected to the connecting rods 29.
