Which grass is best at keeping soil erosion at bay

Ryegrass, dogtooth root, tall fescue, purple fescue, four seasonsand other grass species are commonly used to prevent soil erosion.

Tall fescueIt is a kind of green grass species that is often planted on the slope or on both sides of the road, and it is also commonly used to prevent soil erosion slope protection grass species, it can resist severe cold, can also tolerate drought, and can also grow healthily in a barren and shady environment, and has a strong ability to resist disease, and will not be infected with general pests and diseases, so if you plant tall fescue as a lawn, then you don't need to invest too much labor and cost in the later maintenance, that is, you can do a good job in basic water and fertilizer management. In general, tall fescue is a slope protection grass species that can not only save costs but also play a good role in improving the phenomenon, which can play a significant role in preventing soil erosion and other phenomena.

There are many grass species that can be used to prevent soil erosion, in addition to the commonly used tall fescue, such as the dog's tooth root and black wool we mentioned above, which are all necessary varieties, of course, according to the specific environment of planting.

Then it depends on your soil and meteorological conditions, rainfall and some natural factors, mainly to ensure the erosion resistance of the soil, such as our northeast black soil area of the main grass species is alfalfa.

Purple fescue, early maturing grass, etc., like our Jilin area is also different, the eastern and southern soil composition is mainly dark brown soil, rainfall 600-800, the main grass species is alfalfa, clover.

And so on, the west is mainly saline-alkali land, with rainfall of 300-500, and the grass species is alkali thatch.

Other grass species don't grow either!

Isn't the policy of soil and water conservation "prevention first, comprehensive planning, adapting measures to local conditions, strengthening management, and paying attention to efficiency"?

The principle of adapting measures to local conditions: according to the natural conditions, combined with the characteristics of the project and the local experience of soil and water conservation of similar projects, reasonable screening of prevention and control measures.

Summary. Then it depends on the rainfall of your soil and meteorological conditions, some natural factors, mainly to ensure the erosion resistance of the soil, such as our northeast black soil area of the main grass species is alfalfa, purple fescue, early maturing grass, etc., like our Jilin region is also different, the eastern and southern soil components are mainly dark brown soil, rainfall 600-800, the main grass species is alfalfa, clover, etc., the west is mainly saline-alkali land, rainfall in 300-500, grass species is alkali thatch, other grass species it does not grow!

To prevent soil erosion, the main focus should be on planting trees and grasses to prevent excessive land reclamation, and in some areas, such as hilly areas with high slopes, arable land should be converted into orchards or forestry development.

1. The soil is composed of topsoil and sand and gravel layers, and the topsoil is generally formed by sedimentation or composed of humus layer. This topsoil structure is relatively loose and can be easily carried away by running water. The root system of the plant is relatively large, and it will divide into many branches to absorb nutrients from the soil, which increases the connection between the soil, and blocks the direct impact of rain, which will also play a certain role in soil and water conservation.

2. The roots of the plant will gradually fork from one to two in the growth, two to four, and finally change along the soil and the soil, and the gap between the stone and the stone is drilled down more and more, and finally the soil is tightly locked to form a "sky net", so that there will only be less soil loss.

Forests are so important for nature conservation and ecological balance, especially for soil conservation and water conservation. What kind of plants have the best soil and water conservation ability? Here's how:

1.Plants with particularly well-developed underground stems or root systems that can weave into a strong protective net in the soil and hold soil particles of different sizes tightly, such as cinnamon bamboo, acacia trees, etc.

2.Plants with strong tillering ability and can form large populations in a short period of time, greatly increasing the ability to fix the soil, such as silver acacia, white grass, etc.

3.Those that are easy to plant and easy to reproduce, such as banyan trees, lantana, etc.

4.Those who have strong vitality and can reproduce in the steep slopes where water is scarce, such as mulberry and overlord flower.

According to the "dynamics" that produce soil erosion, the most widespread soil erosion can be divided into three types: hydraulic erosion, gravity erosion and wind erosion. Hydraulic erosion is the most widely distributed, and can occur during heavy rains in mountainous areas, hilly areas and all sloped ground. It is characterized by the fact that water from the ground is used as a power to wash away the soil.

Gravity erosion is mainly distributed in the ravines and steep slopes in mountainous and hilly areas, and on the walls of the ditches on both sides of the steep slopes and ditches, part of the lower part of which is hollowed out by the water flow, and due to the gravity of the soil and its soil-forming parent material itself, it can not continue to remain in its original position, and it collapses in scattered or patches. Wind erosion is mainly distributed in the deserts, sandy lands and hilly covered sand areas in the northwest, north and northeast of China, followed by the southeast coastal sandy land, and then the "Yellow Flood Area" in Henan, Anhui and Jiangsu provinces (historically formed due to the diversion of sediment from the Yellow River). It is characterized by the fact that the wind lifts up the sand grains, leaves their original position, and floats with the wind to land in another place.
