How to determine the direction according to the tree How to use the tree to determine the direction

If it is a whole tree, the branches and foliage on the south side are relatively thick, and if it is a large tree that grows relatively long, the growth rings are denser in the direction of the south. In addition, depending on the local climate, such as what kind of wind is often blowing, trees tend to fall in opposite directions.

Geographically, there are flag-shaped trees, that is, one side is more lush, one side is sparse, and the lush side is generally south, and the trees also grow to the opposite side of the wind.

Now the compass is very cheap, some cars, watches, mobile phones are equipped, and even have GPS, and they are still using the old way to find directions, which is too backward.

Generally, trees grow towards the sun.

The following methods are commonly used to identify directions in the field:

1. Always refer to the map and compass, and actively observe the surrounding terrain and the plants around you to determine the correct location.

2. Take advantage of the sun.

In winter, the sunrise position is south-east and the sunset position is south-west; In summer, the sunrise position is north-east and the sunset position is north-west; Around the spring and autumn equinoxes, sunrise is due east and sunset is due west.

As long as there is the sun, you can use the watch to discern the direction. Read the moment in 24-hour format and divide the number of hours by two to get one hour. Place the watch horizontally on your hand or on the ground, so that the watch is aligned with the direction of the sun at this moment, and the direction of the watch at 12 o'clock is north, and the direction at 6 o'clock is south.

Immediately, a pole is erected vertically on the ground, the shadow points northwest in the morning, and the shadow points northeast in the afternoon, and the shadow is shortest at noon, when the shadow points due north.

3. Use the stars.

Aim for the North Star. First of all, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by 5 times, and then you can find the North Star in this straight line, and the direction of the North Star is due north.

4. Use the ground features to judge the direction.

Large, free-standing trees usually have dense foliage and smooth bark on the south side, and sparse branches and rough bark on the north side. The south side is usually grassy, and the north side is moist and mossy.

For buildings and mounds, snow melts slowly in the north, while in depressions such as earth pits, the opposite is true.

The doors and windows of the larger temples in northern China, the main entrance of the pagoda and the independent houses in the countryside are mostly open to the south.

The northern edge of the forest glade is more grassy. The annual rings of the stump section are generally spaced at a large interval in the south and a small interval in the north.

In the grasslands of northern China, there are many northwest winds in desert areas, and many snow dragons and salons are often formed near the grass, with large heads and small tails, and the direction of the head is northwest.

The doors of the yurts on the steppe are mostly open to the south. The sparse foliage side is south and the dense side is north.

The stump has a dense growth ring, and the side is north.

Put the pin in a puddle with grease and point to the north.

1.The sunny side (i.e., south-facing) of a single tree is dense, while the shady side (i.e., north-facing) is sparse.

2.In dense forests, the south side of the rock is drier, while the north side of the rock is wetter and mossy.

3.Peach and pine trees secrete gum in the south.

4.The rings of the stump are sparse in the south-facing half and denser in the north-facing half.

5.The parts that are difficult for the volume of snow to melt, such as ravines or rocks, are always in the north-facing direction.

6.The ant's burrow is mostly south of the tree, and the hole mouth faces south.

7.Some natural villages are generally concentrated on the south side of the mountain, and most of the gates open to the south. Generally, ancient temples, ancient pagodas, ancestral halls and other buildings are located in the north and facing south.

8.If you can see the stars in the night sky, as long as you find the Big Dipper, you can find the bright North Star along the extension line of the "spoon handle", and the direction of the North Star is due north.

At 6 o'clock in the morning, the sun rises in the east, and the shadows of all objects are inverted to the west; By 12 noon, the sun was due south and the shadow was pointing north; By 6 p.m., the sun was due west and the shadows were pointing east. Therefore, the direction can be roughly determined using the shadow of the sun and the object.

The earth rotates 360 degrees in 24 hours and 15 degrees in an hour, and the hour hand of a watch always rotates twice as fast as the sun. At 6 o'clock in the morning, the sun is in the east, and the shadow points to the west, at this time, the hour hand on the watch points to the sun, and the "12" on the dial points to the west, if the dial rotates 90 degrees, it is half folded at 6 o'clock, so that the "3" on the dial is facing the sun, and the "12" is pointing to the north; At 12 noon, the sun is in the south, and the 12 is split in half, so that the "6" on the dial is facing the sun, and the "12" still refers to the north.

The grass on the south side near tree stumps, trunks, and large boulders grows tall and luxuriant, and the grass on the south side withers and turns yellow faster in winter. The bark is generally smooth in the south and coarser in the north (with many cracks and uneven bumps on the bark). This phenomenon is most pronounced in birch trees.

The bark of the birch tree on the south side is lighter than on the north side and is more elastic.

How to use a big tree to discern the direction.

It seems that the side with dense leaves is sunny, and generally the leaves on the north side are denser than those on the south side. Because the sun does not go directly from east to west, it is slightly northerly at noon.

1. Look at the annual rings, the dense is the south. 2. Look at the branches and leaves, the dense ones are in the south. 3. Look at the fruits, more in the south. 4. Look at the moss on the roots of the trees, less is in the south. 5. Look at the shadow of the tree, the shadow of the tree faces west in the morning and the east in the afternoon.

You sawed open the tree and looked at the rings in the stump, and the dense direction was south.

1. Annual rings. When viewed from the stump, the denser end of the rings is the north, and the other way around. This is closely related to sunlight, the side with sunlight grows blindly, so the rings in the south grow sparsely and loosely, while the north side is dense and firm.

2. Moss. The south side of the ridge and soil slope is dry, and the grass grows luxuriantly; The north side is humid and mossy because there is little sunlight in the north.

3. Bamboo. The greener side of the bamboo body faces south, and the greener side faces north, and the tip of the bamboo is usually upside down to the south in the windless condition.
