Except for eucalyptus and fruit trees, what kind of trees or bamboo should be planted on the existin

Arborvitae, mulberry, tree, acacia! Personally, I recommend Hongsenhuai.

Acacia Hongsen grows rapidly, the wood is hard, the texture is fine, elastic, resistant to water and moisture, anti-decay, and has a wide range of uses, and it is an important fast-growing timber species in China. Hongsen acacia is barren and thin, drought tolerant, and not waterlogging; It grows well on calcareous soil, acidic soil, neutral soil and light saline-alkali soil. Both germination and root tillering are strong.

It is easy to germinate after injury. It has a strong ability to retain water and soil, and has a short lifespan. Shallow root resistance to sulfur dioxide, nitrogen dioxide, hydrogen fluoride, chlorine, ozone, etc., and strong ability to retain dust and soot.

Acacia is an excellent tree species for soil and water conservation, windbreak and sand fixation, soil improvement and greening on all sides. The branches and leaves of the acacia are good fuel, fodder and fertilizer; The flowers are fragrant, are excellent nectar source plants, and can also be eaten. Due to its wide range of uses and strong adaptability, it is the preferred pioneer tree species for afforestation in many places.

I don't know where you are, what the specific situation is. If you are in Guangdong, you can plant ginger flowers under eucalyptus trees. Ginger flowers are now grown in homes by many families as an ornamental plant. The best physical fitness on the market.

Planting trees is a very technical thing. Where to plant what trees should be decided based on reality. You'd better do a survey first.

Fast-growing poplars can be harvested in 8-10 years.

1 acre = square meter.

The distance between the plant and Zheng is 3m 2m = 6 square meters.

About 111 trees.

Eucalyptus planting density has a very important impact on the final yield of eucalyptus, and digging pits determines the final cultivation density. When digging pits, it is necessary to determine the spacing between the pits according to the planting years of fast-growing eucalyptus trees and the growth characteristics of varieties of Bipao, so as to ensure that eucalyptus trees have reasonable permeability in growth, and to avoid wasting soil fertility due to too small planting density. Normally, the density of digging pits can be 3m 2m between rows and plants, and the digging specifications are 1250px 1250px 1000px, and the pins are arranged in a zigzag shape.

In addition, it is necessary to prevent the loss of water and soil flow caused by digging pits, so that the land is prepared first, and then the pit is dug, and the depth of the bottom of the pit should be deeper than 1000px.

The answer to the question of how many eucalyptus trees can be planted on 70 acres of mountainous land will be affected by many factors, such as land quality, topography, planting density, tree age, and so on. Here's a rough calculation:

Planting density: The planting density of eucalyptus trees is generally between 400-800 acres. For the sake of calculation, the planting density here is 600 acres.

Age: Eucalyptus trees generally take about 10 years to mature. For the sake of calculation, the age of the tree is 10 years.

Spacing: The spacing of eucalyptus trees is generally about 2 meters. For the convenience of calculation, the spacing here is 2 meters.

Then, the approximate number of eucalyptus trees that can be planted in 70 acres of mountainous land can be calculated in the following way:

Acreage = 70 acres square meters acres = 282287 square meters.

Number of planted plants = planting area Planting density = 282287 square meter 600 plants mu = 1693722 plants.

Number of mature plants = number of planted trees Age Maturity rate = 1693722 60% in 10 years!=missing) 1016233 strains.

It should be noted that the above calculation results are for reference only, and the actual number of plantings will also be affected by a variety of factors, such as land quality, climatic conditions, tree age, disasters, etc. At the same time, the planting of eucalyptus trees also needs to take into account environmental protection and sustainable development to ensure ecological balance and sustainable resource use.

1 acre = square meter.

Plant spacing 3m 2m = 6 square meters.

About 111 trees.

The planting density of eucalyptus trees has a very important impact on the final yield of eucalyptus, and digging pits determines the final cultivation density. When digging pits, it is necessary to determine the spacing of digging pits according to the planting bend or planting years and variety growth characteristics of fast-growing eucalyptus trees, so as to ensure that eucalyptus trees have reasonable permeability in growth, and to avoid wasting soil fertility due to too small planting density. Normally, the density of digging pits can be 3m 2m between rows and plants, and the digging specifications are 1250px 1250px 1000px, and the pins are arranged in a zigzag shape.

In addition, it is necessary to prevent soil erosion caused by digging pits, so that the land is prepared first, and then the pit is dug, and the depth of the bottom of the pit should be deeper than 1000px.

There are about 80 trees, and my side is meters x 3 meters.

1 mu = square meters Plant spacing 3m 2m = 6 square meters 666 6 = 111 About 111 eucalyptus trees The planting density has a very important impact on the final yield of eucalyptus, and digging pits determines the final cultivation density.

The row spacing of eucalyptus trees is generally 2x3 meters, and about 90 trees are planted per mu. It can be determined according to the local situation.
