Weather suitable for planting trees

June 12 to June 1 every year is the best time to plant trees in winter. The temperature should not be too low to prevent soil hardening from affecting the survival rate, and cold protection measures should be paid attention to in winter seedling raising. When planting, plant deeply to prevent the surface soil from freezing and affecting the seedlings. Pay attention to watering after planting, and cover the soil in time after watering to ensure the soil temperature.

When is the best time to plant trees in winter?

Planting trees in winter is a common work in southern China, usually from February to 10, 65438+ every year. Planting time should not be too late. If it is too late, the colder the weather will affect the survival rate of saplings, which are also planted in northern China.

Problems needing attention in planting trees in winter

Excavation, transportation and anti-freezing

When planting in winter, due to the low temperature, cold and antifreeze measures should be taken during excavation and transportation. Especially for seedlings to be transported for a long distance, soil balls and trees must be protected against cold.

It is best to use straw mats, quilts or vans for protective transportation. The most important thing is not to carry out long-distance transportation, and it is best to take seedlings on the spot and plant them.

Proper deep planting

In order to prevent the roots from freezing, there is a thick frozen soil layer, especially in the northern region. When planting, you can plant it deeply, but not too deep. The depth is generally less than 10cm, which can effectively reduce the root freezing injury.

Choose cold-resistant and frost-resistant tree species.

Winter planting, mainly in the local seedlings, the nearest materials for planting. Avoiding trans-regional transportation and planting between north and south, especially between Jiangnan and Jiangbei, will have a great impact on the survival of seedlings.

Irrigation after planting is permeable.

Although it is winter, it must be watered and ventilated after planting. Not only is the soil closely combined with the root system, but more importantly, the soil temperature is stable after watering.

In this way, some water can be added to the seedlings in time to avoid freezing and pulling in winter. But after watering, the tree tray should be covered with soil in time to avoid freezing.

Dam and weir sealing

The purpose of raising the soil to seal the weir is to raise the ground temperature and reduce the possibility of freezing the tree disk. In addition, the newly planted seedlings have a shallow root layer, and the frozen soil layer can be brought to the stage by cultivating the soil. This can avoid the freezing injury caused by the root layer in the frozen soil layer.

Build windbreaks

There are many cold winds in winter, so a windbreak wall can be built in the direction of incoming wind to prevent cold air from directly invading seedlings, which is beneficial to survival.
