Why have the sheep egg trees, which used to be very common in rural areas, disappeared now?

There is a kind of tree in the countryside, the fruit is oval, one by one, very similar to sheep dung, but it is bigger than sheep dung, this kind of tree used to be a big star level of green plants, you can see it when you go out, "sheep egg" is the name of the place, its green plant is called "neem". When it comes to neem trees, the pot friends in the countryside are no strangers. Neem tree has medicinal effects, which is also used more to see a little, take the root bark of the neem tree, the insect control effect is obvious, often used in medical aspects, even "sheep poop eggs" can be used medicinally.

Neem tree is a very weak greening plant in the reproduction of the woods, of course, the existence of the neem tree in the mountains is only up and down, don't see the neem tree grow and develop in an independent flat area, the harvest is in sight, in the woods all kinds of flowers and trees compete for the sun, the neem tree is formed in the way of large scattered branches, and the height of the tree is far from the other, its effect rate is not low, a tree is only many, dozens. In the woods, birds mostly feed on their fruits, and the seeds that are digested and absorbed by the birds and turned into excrement are unlikely to germinate.

At that time, the neem tree did play some roles, but later, due to the development trend of the pharmaceutical industry, new chemical raw materials appeared, and the neem tree that still grows and develops on the flat ground or grows and develops a lot of fruits for a long time (the light on the flat ground is sufficient), and this kind of fruit falls down and becomes a burden. Children will use it to harm others, or trample on the trampling and fall easily, some will not know that it is harmful and taste poisoning, even free-range cattle, pigs, chickens and other food are poisoned by many conditions.

Neem is a "native tree species" and its sap is harmful. Although the survival rate of seedlings is not very high when planted, once they survive, they will grow and develop at a very fast rate, and if the soil type and fertilizer and water standards are more suitable, they can grow to about 30 cm in diameter in the tenth year after planting. It is also one of the fast-growing tree species.

However, after 10 years, the growth rate will slow down, and it will be difficult for it to grow into a towering tree in the course of its limited life. The material hardness of neem tree is relatively moderate, with more beautiful texture and special fragrance, resistant to corrosion and insects, and is a good material for traditional musical instruments, artworks, decorative design, and furniture manufacturing.

The neem tree is susceptible to insect pests, and farmers don't like it, don't look at the sap of the neem tree is poisonous and has a bitter taste, but Sister Hua especially likes to suck it. If you walk under the tree, you will feel like Sister Hua urinating on your body, which is very uncomfortable. As a result, many farmers don't like the tree, and if anyone has one, they risk being cut down early.

And they are reluctant to plant again after they are cut down. The maximum lifespan of a neem tree is thirty years. After more than thirty years, it will either be "hollow" or die.

As a result, the neem trees will be cut down by farmers when they grow for more than 20 years, so that the number of neem trees, which are not too large, is declining.

Because the survival rate of these trees is not very high when they are planted, and the requirements for the growth environment are particularly high, farmers are troublesome.

Because it doesn't have much value, many people choose to plant other trees, and they disappear.

I think it's cut down, and maybe the tree is withered without watering, and I think everyone's life is getting better and better now, and then no one will pay attention to the sheep and egg tree, so gradually he is dried, and then it may be because some people cut down the tree.

Because of the special clean-up, it is because too many sheep feces and egg trees are planted in the countryside, which leads to air pollution and pungent smells, so they are no longer planted.

It's not suitable for growth. With the progress of the times, the rural living environment is also changing, and the change of climate has led to the fact that it is not suitable for growth.
