How much is the price of a metasequoia seedling in 2019? How does it reproduce?

Metasequoia glyptostroboides is a kind of ancient giant tree, which has strong adaptability and is distributed in some areas of southern China. Metasequoia glyptostroboides has high application value, because the material is very light and soft, so it is suitable for papermaking, building board and so on. The shape of Metasequoia glyptostroboides is also very big, suitable for planting in the courtyard for everyone to enjoy. If you want to raise metasequoia by yourself, you must first buy metasequoia seedlings. How much is the price of metasequoia seedlings in 2019? How does it reproduce?

First, how much is the price of metasequoia seedlings in 2019?

The price of Metasequoia glyptostroboides seedlings in 2019 will be affected by market price, height, DBH, purchase quantity and other factors. For example, the price of Metasequoia glyptostroboides seedlings with a height of 100-130 cm is about 2.50 yuan. Generally speaking, the greater the DBH of Metasequoia glyptostroboides, the more expensive it is. The price of less than 2cm is about 0.5-1 yuan in previous years, and the price of Metasequoia glyptostroboides seedlings larger than 2cm is 2-4 yuan. The price of 5cm Metasequoia glyptostroboides may reach 30 yuan. The price of 20cm is more noble, which may be about 600-800 yuan per tree. If you are specific, you can go to negotiate with people in the seedling market.

When selecting Metasequoia glyptostroboides seedlings, we should pay attention to a few points to ensure the economic benefits of planting:

First, we should pay attention to whether the area is suitable for the growth of Metasequoia glyptostroboides seedlings, and should conform to its growth habits, otherwise it will be difficult to survive.

Second, high-quality Metasequoia glyptostroboides seedlings should meet the prescribed standards in DBH and height, with well-developed roots, more lateral roots and fibrous roots, uniform distribution and no water loss of roots.

Third, we should pay attention to whether Metasequoia glyptostroboides seedlings are damaged during transportation.

Fourth, Metasequoia glyptostroboides seedlings with smooth branches and good maturity without invasion of diseases and insect pests should be selected.

Fifth, pay attention to the water content of Metasequoia glyptostroboides seedlings, we should choose seedlings with fresh bark, less water loss and no wrinkles.

Second, how do metasequoia seedlings propagate?

The propagation methods of Metasequoia glyptostroboides seedlings can be divided into cutting and sowing propagation. Let's take a look at the specific process.

1. Cuttage propagation

Cuttage propagation can be divided into tender branch cuttings and hardwood cuttings, and there are still some differences in time and specification treatment.

The time of tender branch cuttings is from May to June, while the hard branch cuttings are propagated in mid-March after picking branches in January.

If the tender branch cuttings are semi-lignified, the length is about 14-20cm, and the top leaves are reserved as cuttings, the cuttings should pay attention to sunscreen after early cutting, and maintain a moist and ventilated environment. Hardbranch cuttings generally choose pruning with a length of about 10-15cm as cuttings, and then tie them into bundles and put them in sand for softening. During this period, attention should be paid to keeping soil and water moist, suitable air temperature and humidity, and so on.

2. Sowing and reproduction

The mature metasequoia cones were selected and the qualified seeds were screened and sealed in a dry environment after exposure to the sun. When the temperature picks up after March in spring, you can sow seeds and keep the soil and water moist after sowing.

Metasequoia glyptostroboides seedlings, according to propagation methods, as well as different market demand, can be divided into seedling seedlings, grafted seedlings, can be directly used for young tree culture, and grafted seedlings, as the name implies, is used for grafting propagation. Relatively speaking, the price of seedlings will also be higher than that of grafted seedlings.

Seedlings: Metasequoia glyptostroboides, a first-class protected plant in the world, while a seedling with a length of 2 cm costs about 7 yuan, while a seedling with a length of 3 cm costs 13 yuan, while the highest seedling sold on the market is 80 cm. The price can reach about 100,000.

Grafted seedlings: grafted seedlings can be propagated by cuttings directly, and the price will also be lower than that of real seedlings. The height of grafted seedlings sold on the market ranges from 10 to 40 centimeters, and the price ranges from 160 to 9000 yuan.

Factors that affect the price: the price of Metasequoia glyptostroboides seedlings will be judged according to the variety, growth, climatic conditions and improved varieties. Secondly, the most important factors affecting the price of metasequoia trees are the market situation and the degree of demand of consumers. The price of Metasequoia glyptostroboides seedlings in the second half of 2015 is about 5 yuan, more than 3 years old, the price difference will gradually increase.

Rapid growth is one of the advantages of Metasequoia glyptostroboides seedlings, but the performance of seedlings in the young stage is extremely obvious. Once the tree age is more than 15 years, its growth rate will double, while before the age of 50, the average tree type will grow in about 80 cm per year. In the later stage, the tree is more than 100 years old, the growth rate is about 50 cm, and will gradually decline in the later stage.

Seedling sowing

When the sowing time of Metasequoia glyptostroboides seedlings is in spring, the suitable planting temperature is about 25 degrees Celsius. During the sowing time, the temperature that trees can adapt to should not be lower than 12 degrees Celsius.

Seedling yield

The propagation of Metasequoia glyptostroboides seedlings is not strong, and the success rate of sowing and reproduction is less than 50%, so Metasequoia glyptostroboides trees are decreasing year by year. The planting areas with the largest output of seedlings in China are Sichuan and Wuhan.

Seedling density

The propagation of Metasequoia glyptostroboides seedlings is suitable for planting in a large area, and on average, more than 10,000 Metasequoia glyptostroboides can be planted per mu, and the seedling density can be changed according to the needs of transplanting in the later stage. Metasequoia glyptostroboides seedlings can be kept at a distance of about 3 meters. After growing for 15 years, it is necessary to carry out a thinning, which can mainly concentrate nutrients and is beneficial to the reproduction of seedlings of improved varieties.

Seedling disease

Although the reproduction of Metasequoia glyptostroboides seedlings is unfavorable, mastering professional knowledge of diseases and insect pests can increase the survival rate of seedlings, and the most common diseases are mainly yellow leaves, which are serious, which will directly lead to fallen leaves, and gentlemen will also give off a bad smell and touch them with their hands. With a sense of stickiness. Can eat Bordeaux liquid spray, or carbendazim liquid, have a very strong control effect.

Summary: the above is mainly for you to introduce the relevant content of metasequoia seedlings, in view of the picture of metasequoia tree prices, as well as planting methods to do a detailed explanation, I hope it can be helpful to you.

Seedling raising technique of Metasequoia glyptostroboides

Metasequoia glyptostroboides (Metasequoia glyptostroboides), a deciduous tree of Taxodiaceae, is native to China. Because of its conical crown, beautiful posture, beautiful leaves and brown autumn leaves, metasequoia etasequoiaglyptostroboidesHuetCheng is an important tree species in landscaping. The application of cutting propagation is the most effective way to solve the shortage of resources and speed up the construction of Metasequoia glyptostroboides forest, and it is also a feasible and practical seedling technique for expanding metasequoia propagation. The study of winter cutting seedling raising has been carried out in our ecological garden since 2001, and the effect is remarkable. The main results are as follows: 1 the experimental site is located in the north campus of Liaodong University, the north ecological park (total area 133hm2) inside the greenhouse, the area of 400m2, grass curtain insulation, no need for sunshade in winter. Tap water control of underground pipes. The slotting machine is located in the greenhouse, running from north to south, 5m long and 1.2m wide, surrounded by bricks, and the surrounding bricks between the slotting beds are the walkways. First dig 20cm and spread 7~10cm thick fully mature organic fertilizer to provide nutrition supply of seedlings after rooting. Then lay the weathered rock (iron plate sand) newly excavated by 8~10cm as the cutting emperor. The weathered products of mountain rocks are almost free of pathogenic bacteria, do not need disinfection, have good water permeability and water retention, and are stable in chemical properties, which is conducive to the rooting of seedlings. (2) the experimental study on the method of cuttage seedling cultivation showed that the effective seedling growth time of Metasequoia glyptostroboides cuttage was 280 ~ 300 days in solar greenhouse and only 200 days outside, with a difference of 80 days and 100 days. The individual, position, tree age, Lignification degree and the size of the lower cut of the cuttings are closely related to the survival rate of seedlings. 21 cutting time in mid and late December, combined with winter shaping and pruning of Metasequoia glyptostroboides, cutting propagation can be carried out when the air temperature in solar greenhouse is more than 15 ℃ and the ground temperature of 10cm is more than 10 ℃. 22 prepare cuttings to collect branches from tree shaping and pruning, cut cuttings (1-2-year-old branches), treat them at any time, and cut them at any time. The cuttings are 6~10cm in length and have no strict requirements in roughness. The cuttings should be smooth and neat, keeping the cuttings straight as far as possible. The lower cut should be flush, and the slope should not be too large, so as to facilitate the formation of callus and rooting. The buds of Metasequoia glyptostroboides are perpendicular to the branches and often grow below the branch marks where they fall off, so it is difficult to distinguish the reverse direction of cuttings, so they should be neatly discharged and marked after cutting, so as to avoid inverted insertion. In order to facilitate the management of seedling stage after cutting, according to the Lignification degree, thickness and heel of cuttings, the cuttings were stored and cut respectively. After the cuttings are cut, the upper cut of the cuttings is sealed with melted wax, and the wax must be sealed tightly to reduce the loss of water and avoid cutting infection. 23 cutting first use a pointed stick thicker than cuttings, punch holes according to the row spacing of 3cm × 4cm plants, and deep 6~8cm. Then the cuttings were inserted into the hole and compacted, and the depth after cutting was 5cm. Watering with a spray can in time after insertion, the water should be thoroughly watered, not too large, so that the seedbed cuttings should be in full contact with the cuttings, and the cuttings should be straight. 24 Management of cuttings after cutting, the temperature in the greenhouse should be controlled at 15: 25 ℃. If the temperature is too low, it will not take root, but if the temperature is too high, it will inhibit rooting. The ground temperature of 10cm should be kept above 10 ℃ and the relative humidity should be controlled at about 80%. According to the weather conditions and indoor temperature and humidity, water can be watered once in 10 days or so, and the leaf surface can be sprayed to cool down. Metasequoia glyptostroboides takes root slowly. After 30-45 days, the winter buds of cuttings begin to sprout, draw leaves and elongate new shoots, but they are still "false living" and should be maintained for 2 months before they really take root. In February, the leaves gradually expanded, the base of the cuttings expanded, and began to take root gradually at the beginning of April, with a general rooting rate of more than 95%. The cuttings with high degree of Lignification had sufficient soluble sugar in branches, strong activity of superoxide dismutase, early healing of lower cut and faster rooting, while cuttings with low degree of Lignification had thin, weak and tender branches, easy to lodge and rot after cutting, strict requirements for temperature, humidity and moisture, difficult management and slow rooting. The cuttings with tight wax seal on the upper cuttings had almost no cutting infection, and the cuttings grew normally and had strong stress resistance. The cuttings with flat cuttings have the advantages of small cut, quick wound healing, early rooting and high rooting rate. Although some cuttings have healed, they do not grow roots for a long time, so they can be transplanted to a good breathable seedbed, strictly control the temperature and humidity, and most of them can take root.
