Where can I buy slash pine seeds? What are the seedling-raising methods?

Slash pine is an evergreen fast-growing arbor species of the pine family (Pinaceae). Its place of origin is the low-altitude areas of the southeastern United States. Because it has strong adaptability and stress resistance, it has been introduced and cultivated in China for many years. As a pine species with continuously improving economic benefits, slash pine is a deep-rooted tree species and needs large planting holes, which is beneficial to later tree growth. So where can I buy slash pine seeds? What are the seedling-raising methods? Let's learn about them together.

Where can I buy slash pine seeds?

Slash pine can grow on various terrains such as flat land, hills, mound land and mountainous land, and it grows best especially in the hilly mound land and middle- and low-mountain sites of the middle and lower reaches of the Yangtze River. At present, slash pine cultivation production areas are found throughout Wuhan in Hubei, Ji'an in Jiangxi, Anji in Zhejiang, Nanjing in Jiangsu, Guangzhou in Guangdong, Liuzhou in Guangxi, as well as Taiwan, China and other places. Therefore, there are still many places where slash pine seeds can be bought. You can go directly to local enterprises or the seedling market to buy them, but because slash pine seed prices are relatively expensive, most people also choose to buy online, but you should also pay attention to purchasing techniques and not simply covet small bargains.

What are the seedling-raising methods?

1. Land preparation

After the vegetation on the plot where slash pine is to be planted has been cleared, flat land, hills and mound land can be prepared by mechanical land preparation, that is, a small excavator digs holes and turns the soil deeply according to a 2 m * 3 m spacing between rows and plants, first backfilling the topsoil, then covering the surface of the pits with the subsoil.

2. Planting

Obtain robust first-grade slash pine seedlings, requiring a complete root system, no pests or diseases, no frost-damaged tips and no mechanical damage. When planting, first clear the soil in the hidden hole, place the slash pine seedling in, backfill with loose soil, gently lift the seedling so that the seedling roots spread out, then backfill with loose soil again, tread it firm, and finally cover the seedling roots with loose soil.

3. Seedling raising

In production, hotbed sprout-shifting seedling raising is generally used, and two main technical measures are usually adopted, namely seed soaking and disinfection and building a hotbed. Seed soaking and disinfection means washing the seeds clean, then drying them, then soaking them in 0.1% "benzalkonium bromide" for disinfection for 30 minutes, and after rinsing clean, drying them and soaking them in the hotbed, which can prevent seed rot caused by pathogen infection. For building a hotbed, choose a nursery site that is sheltered from the wind, faces the sun, has convenient drainage and irrigation and is close to the sprout-shifting site.

But now most people are willing to choose container seedling raising, mainly because its seedling period is short and its yield is high. The quality is also relatively good, the survival rate is high, and the growth speed is also very fast. Generally, seedling raising can be done in spring and autumn.

4. Management and protection

After planting, inspect regularly to check whether there are dead seedlings, and if there are, replant the seedlings. In addition, attention should be paid to weeding and fertilizing, and the area around the saplings should be cleared clean, so as to facilitate light and ventilation for the saplings. If the saplings have many branches, they should also be pruned, and the side branches should be cut appropriately so that nutrients can be fully absorbed.

Overall, slash pine's adaptability is still relatively strong, and it generally grows much better than similar plants, and the threat of pests and diseases is also relatively small. When introducing and cultivating it, growers only need to focus on seedling management and seedling-stage care, and then slash pine can grow quickly and well.
