Description

Technical Field

[0001] The invention relates to the field of plant protection, and in particular to a device for improving the survival rate of resource fir seedlings in the wild and a use method thereof. Background Art

[0002] Resource fir is an evergreen tree of the genus Abies in the Pinaceae family. Wild plants are rare and mainly remain in some mountains above 1,700 meters above sea level in Guangxi, Hunan and Jiangxi. Due to its narrow distribution range, small population and individual numbers, and the difficulty in renewing population seedlings, it is listed as a national first-class key protected wild plant and China's first batch of extremely small population wild plants.

[0003] The adult plant of Abies truncatum can reach up to 25 meters, which is a very tall tree species. However, its seedlings grow very slowly within three years after germination. The average plant height of three-year-old seedlings is only about 10 cm, and the average base diameter is only about 0.08 cm. The short and thin seedlings of Abies truncatum are very susceptible to the following five hazards and death in the wild environment: first, continuous drought in summer causes water loss at the roots of seedlings; second, the squeezing and covering of dead branches and leaves of upper plants; third, the burial effect of soil or humus layer formed by surface runoff in rainy season; fourth, direct impact of strong winds and heavy rains; fifth, trampling and eating by small and medium-sized wild animals. Within three years after the germination of Abies truncatum seedlings, the above five hazards can cause the death of about 76% of the seedlings, which is the main cause of death of Abies truncatum seedlings in the wild.

[0004] In order to protect the resource fir seedlings in the wild environment and safely pass through the very fragile seedling period, it is necessary to carry out very detailed rescue, including cleaning the dead branches and leaves, preventing mud and water erosion, and maintaining sufficient soil moisture. However, since the wild resource fir grows in the middle and upper parts of the remote high mountains, far away from human activities, artificial rescue such as the above requires a lot of manpower and financial investment, making it difficult to sustain the rescue of resource fir seedlings. Therefore, it is urgent to develop a device suitable for protecting resource fir seedlings in the wild, and to take targeted protection for fir seedlings in the wild to improve their survival rate, which is of great significance to reducing the cost of artificial rescue of resource fir seedlings in the wild and promoting the development of this population.

When the humidity in the soil does not meet the requirement, the controller (5) controls the power storage device to energize and open the solenoid valve in the water outlet channel (9) at the bottom of the water tank (7), so that the stored rainwater enters the irrigation structure to irrigate the soil.

9. The method for using the device for improving the survival rate of resource fir seedlings in the wild according to claim 8, characterized in that: When the height of the fir seedlings is 4-6 cm, the soil moisture is controlled at 70%-80% by a humidity sensor (17) and maintained for 365 days; When the height of the fir seedlings is 6-10 cm, the soil moisture is controlled at 60%-70% by a humidity sensor (17) and maintained for 365 days; When the height of the fir seedlings is 10-15 cm, the soil moisture is controlled at 60%-65% by a humidity sensor (17) and maintained for 365 days; When the height of the fir seedlings is greater than 15 cm, the device is removed.
