Is the seedling of Pinus sylvestris var. mongolica expensive? What are the key points of overwintering management?

Pinus sylvestris var. mongolica is a kind of tree from the Daxing'an Mountains, because of its strong adaptability and good material, it is very suitable for planting in the courtyard or as a greening tree species. The seedlings of Pinus sylvestris var. mongolica are very resistant to drought and barren, and their diseases and insect pests are very few compared with other tree species. Even if the disease occurs, it is relatively easy to treat. It is indeed a good seedling for wind prevention, sand fixation and barren mountain afforestation. Today, let's find out whether the seedlings of Pinus sylvestris var. mongolica are expensive. What are the key points of overwintering management?

Is the seedling of Pinus sylvestris var. mongolica expensive?

1. Is the seedling of Pinus sylvestris var. mongolica expensive?

The seedling price of Pinus sylvestris var. mongolica is expensive, which is mainly affected by rice diameter, height, crown width, ground diameter and other factors. The price of Pinus sylvestris var.mongolica pine seedlings in the following market for your reference: Henan seedlings flowers and trees garden nursery field high 300cm price in RMB260A; Zidong seedlings high 120cm, crown 60cm price in 15 yuan or so; Dalat Banner tree height around the 350cm price is 110yuan a tree, to sum up, different seedling market price difference is relatively large, we can go to the field to negotiate prices to see if it is cheaper.

2. Classification of seedlings of Pinus sylvestris var. mongolica.

If it is divided according to whether there is a container bag, it can be divided into seedlings with container bags and seedlings without container bags.

If it is divided according to the age, it can be divided into annual Pinus sylvestris var. mongolica pine seedlings, biennial Pinus sylvestris var. mongolica pine seedlings, three-year Pinus sylvestris var. mongolica seedlings and perennial Pinus sylvestris var. mongolica seedlings.

Second, what are the key points of overwintering management of Pinus sylvestris var. mongolica seedlings?

1. Why overwintering management?

Although the seedlings of Pinus sylvestris var. mongolica are very resistant to cold and can grow healthily even when the temperature is very low, the winter climate is very dry, so the seedlings of Pinus sylvestris var. mongolica will easily lose water and die because of lack of water in the long run. So in winter, we must help the seedlings of Pinus sylvestris var. mongolica to survive the winter smoothly according to the climatic characteristics.

2. Specific methods of overwintering management.

The seedlings of Pinus sylvestris var. mongolica can be covered with soil to maintain the temperature, which can reduce the growth of seedlings due to external climate, the water-locking ability of seedlings can also be enhanced, and the mortality rate of seedlings covered with soil heat preservation is relatively low. if it is covered with grass to survive the winter, the mortality rate is high every day.

It should be noted that although soil mulching can reduce seedling mortality and help survive the winter smoothly, it is not recommended to cover the soil too early, otherwise there will be seedlings rot of Pinus sylvestris var. mongolica. The most appropriate time is to cover the soil before the soil freezes in autumn, that is, at the end of October and early November. The specific mulching method is as follows: first pour the seedlings of Pinus sylvestris var. mongolica with water a week before covering the soil, then press the seedlings in one direction, and then cover the seedbed after the soil is broken. The approximate thickness of the cover is to bury all the seedlings under it. When the temperature picks up in spring and the soil thaws, the soil can be removed.

It is worth noting that the removal of soil should be divided into two stages, one is to withdraw half, after the withdrawal should be timely watering.
