๑. หญ้าแฝกเป็นพืชที่มีระบบรากลึก แผ

First. Vetiver plants with deep root systems. Spread into the soil directly into a wall panel. Filter sediment and help maintain soil should be well
.Take the test to test vetiver planted to prevent soil erosion in the study area and other areas as widely

2.The experimental vetiver. Consider the nature of the terrain. They are divided according to the following areas: A.Planting grass on a mountain. To plant vetiver grass across the slope of a mountain and in the gutter. To prevent soil erosion and help retain moisture in the soil
with
b.Planting grass on the plains. To carry on like this
-
planted by the conversion - convert the plant into one or two lines
- for converting crops. The grooves alternate with crops grown by
c.Planting grass around the pool. To prevent them from shallow reservoirs due to sediment from soil erosion. It helps to maintain the soil above the sink and let
forest areas by increasing the water rise quickly
d.Planting grass above the water. Vetiver plant defense and filter sediment and wastes that flow into the water to save the image
prior to and after the implementation of the evidence

3.The results of an experimental study. Should collect data on the growth of stems and roots. The ability to preserve the integrity of the soil and retain moisture in the soil and grass, various species

.The Highways Agency is an agency of the importance of conserving soil and water resources. Including the environmental impact due to erosion of soil slope road.They have defined a policy for the maintenance and construction departments. The new highway cut the vetiver to prevent erosion of the soil embankment slope and embankment on the north slope of each line.Videotape and prepare planting vetiver on the application. Techniques of vetiver in the way
.
.ใka the target area of ​​the highway is vetiver. A cut above the embankment slope (back slope) land reclamation embankment slope (side slope) high and are likely to cause erosion of the soil. For line in northern mountainous areas.And the Northeast. Most of which is covered with sandy soil decomposition of granite and sandstone. A target area to prevent soil erosion and soil conservation.

1. Vetiver grass is a plant that has spread deep into the root system distribution on Earth, making a straight wall-like Panel filter sediments and soil, soil screen, well it should be
. Alternative education Try planting. Try planting vetiver grass to prevent erosion of soil in the area of Development Studies Center and other areas that are suitable and somayangkwang

2. The trial operation of planting vetiver, consider the characteristics of the terrain, broken down by nature of space as follows:
. G Planting vetiver grass mountain, vetiver planting across the slope and in the Groove of the mountains. In order to prevent the erosion of soil moisture in storage and provides a constant DIN.
. ข. Vetiver grass cultivation on slopes, in a manner like this:
-
conversion by planting-planting into conversion. Converts a vertical 1 or 2
- For converting crops to planting crops according to Groove
c. Planting vetiver grass around the pool to prevent the reservoir, the shallow due to sediment from soil erosion, as well as helping to maintain the soil above the forest and help sink
areas get water thawi completion quickly through shit
. Discography. Planting vetiver planting vetiver as a water source area over the protective soil sludge and waste water flowing into the well, capture
. Before and after the operation as evidence

3. The results of experimental studies. All data should be stored on the growth of stems and roots. The ability to preserve the integrity of the soil and keep moisture in the soil, and various species of vetiver grass story

. By the Department of highways is one of the agencies, the importance of soil and water resources conservation, including environmental impacts due to erosion of the soil-slope road. Generally defined as the maintenance agency policy and construction on the highway, especially cut new planting vetiver grass to prevent erosion of soil slope North Slope vehicles and vehicles for various cables. And vetiver planting project TV video about applications. Technical method of planting vetiver in.

Target area of vetiver-mounted plasma display plant operations Department of highways is a complex approach of soil cut above Khan (Back Slope) slope-land reclamation car (Side Slope) and tends to cause erosion of the soil. For the mountain in northern areas. And the Northeast, where most of the land covered with sand "comes from the granite and sandstone is the target area in order to prevent the erosion of soil and soil conservation.

1.grass thatch is a plant that has a deep root system spread down to the ground, it is like a wall panel to filter sediment soil and keep the soil well, it should be brought
Learn to carry try planting, try planting grass thatch to prevent the collapse of the soil in the area Study Center for the development and other areas that are spacious

2.The trial run of planting grass thatch, consider the characteristics of the geographical features of the area that can be divided into the following:
a.The planting grass thatch thatch grass planting on the mountain, along the cross section of the steep mountains and in the ditch to prevent the collapse of the land
and keeps moisture in the soil is a
b.elephant grass planting grass on a flat surface, in a manner as follows:
-
planted around convert - Convert convert plant in a 1 or 2 line
- farm crops for conversion to switch to farm crops planted along
C.The planting grass thatch around the pool to protect Reservoir, due to shallow sediments from the collapse of the soil as well as help maintain soil over
bath and help forest in the area is given to complete the water multiply rapidly,
d.The planted with grass thatch thatch is planted over the water source line of defense land, and sediment filter, the flow of waste into the water source, save the picture
before and after the action is performed as evidence

3.The results of the experimental study data should be stored in the trunk of the growth of the roots and can be in the conservation of the integrity of the soil and keep the moisture in the soil and thatch Grass species,

with the Department of Highways is one of the agencies, the importance of soil and water conservation of resources and the impact on the environment due to the collapse of the soil wash-slope RoadBy policy, the agency maintenance and construction of the highway, especially the new-cut continue to plant grass thatch to prevent the collapse of the soil washes down the steep slope and over the cars in the line.Create and video vision about the planting grass thatch thatch grass planting techniques applied in the

TARGET AREAS planted with grass thatch at the action of the Department of Highways, Aladdin is cut above the units (Back Slope) of Aladdin, the floes (Side Slope) high and are likely to be a wash for the collapse of the soil in the northern mountainand in the Northeast, mostly covered with sandy soil that breaks down the granite and Sandstone is a target areas to prevent the collapse of the soil dust and soil conservation
