Are Pinus sylvestris var. mongolica seedlings expensive? Detailed explanation of overwintering management key points

Pinus sylvestris var. mongolica is a tree originating from the Greater Khingan Mountains region. Because it is highly adaptable and has excellent wood quality, it is very suitable for planting in courtyards or as a landscaping tree species. The seedlings of Pinus sylvestris var. mongolica are very drought-tolerant and tolerant of poor soil, and compared with other tree species they have very few pests and diseases. Even when disease occurs, it is relatively easy to treat. It is indeed a good seedling for windbreak and sand fixation and afforestation of barren hills. Today let us learn together about whether the price of Pinus sylvestris var. mongolica seedlings is expensive? What are the key points of overwintering management?

I. Are Pinus sylvestris var. mongolica seedlings expensive?

1. Are Pinus sylvestris var. mongolica seedlings expensive?

The price of Pinus sylvestris var. mongolica seedlings can be considered expensive, and is mainly affected by factors such as meter diameter, height, crown width and ground diameter. The following market prices for Pinus sylvestris var. mongolica seedlings are provided for everyone's reference: at the Henan Nursery Flower and Tree Garden Nursery, the price for a height of 300 cm is 260 yuan per tree; at Zidong Nursery, the price for a height of 120 cm and a crown width of 60 cm is about 15 yuan per tree; at Dalad Banner Shumuyuan Nursery, the price for a height of about 350 cm is 110 yuan per tree. In summary, prices vary considerably among different seedling markets, so you can go to the site to negotiate the price and see whether it is cheaper.

2. Classification of Pinus sylvestris var. mongolica seedlings

If classified according to whether they have container bags, they can be divided into seedlings with container bags and seedlings without container bags;

If classified according to tree age, they can be divided into one-year-old Pinus sylvestris var. mongolica seedlings, two-year-old Pinus sylvestris var. mongolica seedlings, three-year-old Pinus sylvestris var. mongolica seedlings and multi-year-old Pinus sylvestris var. mongolica seedlings.

II. What are the key points of overwintering management for Pinus sylvestris var. mongolica seedlings?

1. Why is overwintering management needed?

Although Pinus sylvestris var. mongolica seedlings are very cold-tolerant and can grow healthily even at very low temperatures, the winter climate is very dry, so the seedlings easily lose water, and over time they can easily dry out and die from lack of water. Therefore, in winter it is necessary to help the seedlings overwinter successfully according to the climate characteristics.

2. Specific methods of overwintering management

Pinus sylvestris var. mongolica seedlings can be covered with soil to maintain temperature. This can reduce the impact of the external climate on seedling growth, and the water-retention capacity of the seedlings can also be enhanced. The mortality rate of seedlings after soil covering for warmth is relatively low, whereas the mortality rate of those covered with grass for overwintering is generally high.

It should be noted here that although covering with soil can reduce the mortality rate of seedlings and help them overwinter successfully, it is not recommended to cover with soil too early, otherwise the Pinus sylvestris var. mongolica seedlings may rot. The most suitable time is in autumn before the soil freezes, specifically from the end of October to the beginning of November, when soil covering should begin. The specific covering method is as follows: one week before covering with soil, water the Pinus sylvestris var. mongolica seedlings thoroughly, then press the seedlings down in one direction, then break up the soil and cover it over the seedbed. The approximate covering thickness is to bury all the seedlings underneath. When spring temperatures rise and the soil thaws, the soil can be removed.

It is worth noting that removing the soil should be done in two stages, removing half at a time, and after removal, water promptly.
