How to protect the native rare plants of Acer truncatum in Taiwan? Nursing of planting and pulling grass for Acer truncatum

Taiwan triangle maple, do you know this plant? At present, the number of this kind of plant is small. In this regard, to cultivate this native rare plant, there are special people to plant this plant.

Ramet colonization

On this day, everyone gathered in the big greenhouse. at first, they opened two large bags of dielectric soil and mixed them with white perlite. The volunteers took turns mixing the soil fully with a shovel, then sprinkling water finely, mixing the medium soil, and piling up a hill. Lin Jianrong, an assistant researcher at the Fushan Research Center, explained the day's work. Several volunteers were responsible for collecting in the field last year, sowing the Taiwan maple with roots, splitting and planting.

Xi Xi first poured the Taiwan triangle maple out of the basin carefully, and the root system was slender and complete at a glance. He carefully separated the roots from one plant to another and assigned them to the pot. on the one hand, he marked the name, provenance, and date on the label, and then Xiong Dad and Guilan were responsible for covering the soil, compacting, completing the planting, inserting labels, and rows of small Taiwan maple plants. stand on the greenhouse rack and receive regular water irrigation.

Taiwan triangle maple (Acer buergerianum var.) Formosanum) is a vascular plant species classified as CR in the Red Book. It is distributed along the north coast and in the coastal waters or valleys of Ilan. It shares the same fate as most threatened plants: loss and fragmentation caused by gathering pressure and habitat close to human activities.

Tonifying soil for health diagnosis

Zheng Yingzhi and Zhang Ziwen went to several tunnel net rooms to check the soil condition of each potted plant one by one, and brought the potted plants that needed replenishing soil back to the big greenhouse. Which potted plants need to be mended? In appearance, the plant appears to be sunken, which may be the loss of media at the bottom of the basin.

Lin Jianrong explained that the process of watering over the years will inevitably lead to soil loss in the basin, resulting in the root system of planting hanging in the air. If the root system hangs in the air for a long time, the plant must become weaker and weaker, and the root hair that cannot absorb water will die. Therefore, it is necessary to regularly check the soil condition of potted plants and find that plants are not in good condition, and they will evaluate soil replenishment to avoid affecting growth due to lack of soil.

The two men first separated the plant from the basin, and then added new soil to enrich the soil in the basin. In the process, take advantage of the opportunity to organize and plant, pull up grass, remove dry and dead plants, and make the pot more refreshing.

If the bottom is hollowed out, it is difficult to judge from the appearance, which depends on the careful observation of frequent inspections all the year round. Lin Jianrong spends some time every day working in the nursery, checking the condition of the seedlings and the causes of failure, slowly accumulating practical experience from the process, and increasing the chances of plant reproduction and survival.

Pull the grass

Fukuyama is surrounded by the natural environment, and the problems of wildlife and water must be taken into account, so plants are grown without drugs at all; the relative demand for manpower is very high. The most important job in the nursery is to pull out weeds. Volunteers always have endless weeds to pull. In addition, although the nursery does not restrict the use of fertilizers, it hardly uses them, which implies manpower considerations. "after fertilization, weeds grow better than the target plants. "Lin Jianrong said.

The next morning, the volunteers devoted themselves to the cleaning of weeds in the greenhouse, relying entirely on their hands. Do not think that only the grass in the open-air nursery grows fast and much, and all kinds of plants in the greenhouse are thriving on the ground, in the basin, and on the shelf, but some non-target plants have to be treated as weeds, and the process must be handled carefully so as not to damage innocent ── target plants.

Zheng Yingzhi said that the key point of weeding is to remove the roots. You can't just clean up the green leaves on the ground. You must pick up the roots with your hands and remove them as much as possible to delay its growth. Moreover, not a single piece of grass is allowed to be missed carelessly. Guilan is the most junior of several volunteers, but they have also served for more than three years. He said that every time there are always endless weeds, especially when working in the sun in summer, it is very hard to encounter tenacious roots. It is a strange experience for small snakes to visit the open-air nursery occasionally.

The grass on the shelf of the nursery should also be cleaned up. For some overgrown and anti-guest potted plants, sometimes they can't tell who the protagonist of the potted plant is, so they have to look for it according to the clue, look at the display board, or consult Lin Jianrong. However, most of the plant identification can not beat Xi Xi, after finishing, the protagonist in the potted plant finally showed up.

As a matter of fact, there is no shortage of weeds endemic to Taiwan, such as Taiwan-endemic species, native species, and so on, but in order for the target plants to grow well, they have to be removed. But they will soon grow back!

While pulling up weeds, while following the recognition of plants, the nursery always has new plants to move in, taking advantage of the opportunity to learn plant knowledge. For Zheng Yingzhi, constantly learning new knowledge attracts him deeply.

Volunteers believe that attendance has a healing effect, especially pulling weeds. Xi Xi said that every time he came, he could put his body and mind down. He usually worked as an interpreter and guide in other places, and went to Fukuyama so that he could keep his mouth shut and only chat with his friends. His sense of achievement is based on making plants live better; especially during flowering, watching every flower in full bloom and filling the heart with beauty.

In addition to mixing soil, planting and pulling grass, volunteers also provide services such as bed moving, planting, and tree pruning in the botanical garden. There are more than 3000 plants in the nursery of Fushan Botanical Garden. Under the guidance of researchers and the painstaking hands-on operation of volunteers, a suitable base for plant conservation has been built.
