Description

Technical Field

[0001] This invention relates to the field of red poplar seedling cultivation technology, and in particular to a device and method for cultivating red poplar seedlings with high tannin content. Background Technology

[0002] Red poplar leaves have a high tannin content, making them an excellent parasitic carrier for gallnuts, which are an important raw material for extracting tannins. Red poplar is one of the core host tree species for gallnut production. It belongs to the same genus as sumac in the Anacardiaceae family and is the best host plant for gallnut aphids. Gallnuts are formed by gallnut aphids parasitizing the leaf rachis, wings, leaflets, or shoots of sumac plants, stimulating abnormal proliferation of plant tissues. Gallnut aphids usually use moss as their overwintering host, and the cultivation quality of the summer host, red poplar, directly affects the gallnut yield.

[0003] Current methods for cultivating high-tannin-content poplar seedlings often result in excessive watering of the ground moss during watering, hindering moss growth and making it difficult to isolate and cultivate poplar independently. Furthermore, traditional methods for obtaining gallnuts from poplar require manually placing gall aphids on the poplar, a cumbersome process that doesn't easily create a direct aphid passage between the poplar and moss. It also makes it difficult to protect the remaining gallnuts, which are easily affected by rain and other factors, leading to rotting and impacting the gallnut yield. Summary of the Invention

The moss water supply component 2 can be used in conjunction with the cultivation separator 1 to facilitate the independent cultivation and watering of red poplar and moss by the staff. It can be more suitable for the different water requirements of the two and can improve the growth quality of red poplar and moss. The structure is simple and ensures that moss is cultivated under the red poplar forest. Aphids are more likely to parasitize the red poplar. At the same time, the moss water supply component 2 can cover the moss to help protect the moss when spraying pesticides and weeds under the forest, and further ensure the normal growth of the moss. The fastener 3 can be used to fasten the moss water supply component 2. It can automatically control the prompt when it is forgotten to fasten. Water is sprayed through the nozzle pipe 202 to keep moist. Water can be atomized to keep moist. Excess water can overflow through the drainage net 102 to avoid the moss being over-soaked when watering red poplar.

[0040] In this embodiment, the seedling water supply component 5 includes: a water supply mounting shell 501, a water supply pipe 502, a sludge removal rod 503, and a stop plate 5031. The water supply mounting shell 501 is slidably inserted into a notch on the side of the separating cultivation shell 101. The water supply pipe 502 is sleeved on the water supply mounting shell 501. A filter hole is provided on the outside of the water supply pipe 502. The sludge removal rod 503 is sleeved inside the water supply pipe 502, and a stop plate 5031 is provided at the bottom of the sludge removal rod 503, and the stop plate 5031 is sleeved inside the water supply pipe 502. The anti-clogging component 6 includes: an anti-clogging fixing plate 601 and a collar 6011. The anti-clogging fixing plate 601 is fixedly installed on the water supply mounting shell 501 by bolts. The collar 6011 is fixedly installed at the bottom of the anti-clogging fixing plate 601, and the collar 6011 is sleeved at the bottom of the water supply pipe 502. The plate 601 has two raised strips attached to the side of the water supply pipe 502; the anti-clogging component 6 also includes: cleaning steel bristles 602. The cleaning steel bristles 602 are provided on the inner side of the anti-clogging fixing plate 601 and are attached to the outer side of the water supply pipe 502. The seedling water supply component 5 can facilitate independent watering of the red poplar without affecting the normal growth of the moss. It can be used with the stop plate 5031 to remove silt and prevent the accumulation of silt inside the water supply pipe 502. The cleaning steel bristles 602 can be used to brush and clean the filter holes on the water supply pipe 502 to prevent the filter holes from being blocked by capillary roots and other factors, which would affect the water flow. The structure and operation are simple. The silt removal rod 503 is pulled out periodically, which drives the stop plate 5031 to scrape out the silt for easy cleaning. At the same time, the water supply pipe 502 can be rotated to drive the water supply pipe 502 to be brushed and cleaned by the cleaning steel bristles 602.

[0041] In Example 2, based on Example 1, the branch enclosure 4 includes: a connecting pipe 401, a sleeve cover 402, and a connecting rope 403. The bottom of the connecting pipe 401 has a groove. The connecting pipe 401 is fixedly sleeved on the water supply cover 201. The connecting pipe 401 passes through the water supply cover 201. The sleeve cover 402 is fixedly installed on the connecting pipe 401. The sleeve cover 402 is made of waterproof cloth. The connecting rope 403 is fixedly connected to the outside of the sleeve cover 402. The branch enclosure 4 also includes: a tightening rope 404 and a guide pipe 405. The tightening rope 404 is fixedly pasted to the outside of the sleeve cover 402; the tightening rope 404 is used to tie and wrap the end of the sleeve cover 402 around the branches of the red poplar; the end of the connecting rope 403 is fixedly installed with a guide tube 405, and the guide tube 405 is used to allow aphids to pass through; the sleeve cover 402 is used to be sleeved on the gallnut branches that need to be retained. The use of the branch wrapping component 4 is more suitable for the cultivation of red poplar, ensuring the subsequent yield of red poplar, and can effectively carry out protection work, because when the red poplar gallnuts are harvested, By leaving a portion of the gallnuts unremoved, aphids inside can continue to parasitize them the following year. This structure uses a sleeve 402 to protect the unremoved gallnuts from rotting due to rainfall or other issues. Simultaneously, the connecting tube 401 provides a passage for aphids. After the remaining gallnuts fully mature and split open, the aphids crawl to the moss inside the separating cultivation shell 101 to overwinter. This also facilitates the aphids' subsequent re-parasitism on the branches of the red poplar after overwintering. This design offers greater flexibility and avoids the tedious manual placement of materials on the main trunk of the red poplar. The method addresses the cumbersome issue of aphid control by offering greater flexibility. The use of the grafting cover 402 improves aphid survival rates, ensuring the quality and yield of gallnuts from the cultivation of red poplar. The operation is simple: the end of the grafting cover 402 is tied and wrapped around the red poplar branch with the tightening rope 404 for protection. As aphids overwinter, they will crawl to the moss. When they crawl back to parasitize the red poplar the following year, the tightening rope 404 can be loosened, the guide tube 405 can be placed inside the grafting cover 402 and attached to the branch, and then the tightening rope 404 can be rewound.

[0042] A method for cultivating red poplar seedlings with high tannin content:

[0043] 1. Plant red poplar on the ground, place the dividing cultivation shell 101 on the outside of the red poplar and keep it in the center, insert the water supply installation shell 501 into the dividing cultivation shell 101, add water above the water supply pipe 502, and water the red poplar roots through the water supply pipe 502.

[0044] 2. Pull out the sludge removal rod 503, which will drive the stop plate 5031 to scrape out the sludge; manually rotate the water supply pipe 502, which will be cleaned by the cleaning steel bristles 602.

[0045] The working principle of this embodiment is as follows: First, after planting the red poplar in the ground, the opening on the side of the dividing cultivation shell 101 is used to facilitate placing the dividing cultivation shell 101 outside the red poplar and keeping it centered. After the dividing cultivation shell 101 is inserted into the red poplar, the water supply installation shell 501 is inserted into the dividing cultivation shell 101. Holes can be drilled in the ground to facilitate the subsequent insertion of the water supply pipe 502. When water needs to be added, water can be added above the water supply pipe 502 to supply water to the root system. The silt removal rod 503 can be pulled out periodically, driving the stop plate 5031 to scrape off the silt for easy cleaning. At the same time, the water supply pipe 502 can be rotated to clean the water supply pipe 502. Use a steel wool 602 brush to clean and prevent clogging; you can fill soil inside the partitioned cultivation shell 101 to cultivate moss, and then put the water replenishment cover 201 on the partitioned cultivation shell 101. Manually connect it to the fixing block 103 by fastening bolt 301. Tighten the fastening bolt 301 to drive the positioning switch 302 to squeeze the inside of the fixing block 103 and control the extinguishing. This prevents forgetting to tighten the water replenishment cover 201. When you need to replenish water for the moss, you can turn on the water pump connected to the water pump connection pipe 203 and spray water through the nozzle pipe 202 to keep it moist. Excess water can overflow through the drainage net 102 to avoid the moss being over-soaked when watering the red poplar.

[0046] When harvesting gallnuts, the gallnut branches that need to be retained can be directly grafted using a grafting cover 402. Then, the end of the grafting cover 402 is manually tied and wrapped around the branch of the red poplar using a tightening rope 404 for protection. As aphids overwinter, they will crawl to the moss. When they crawl back to parasitize the red poplar the following year, the tightening rope 404 can be loosened, and the guide tube 405 can be placed inside the grafting cover 402, attached to the branch. The tightening rope 404 is then wrapped around the cover again to fix the guide tube 405, making it easier for aphids to pass through the guide tube 405 and crawl to various parts of the red poplar to re-parasitize the branches. This stimulates abnormal proliferation of plant tissue to form galls, avoiding the problems of cumbersome indoor moss cultivation, space occupation, and high construction costs of cultivation rooms.
