CN1386935A - Method for controlling desert by anatropal grass vegetation - Google Patents

Abstract

A method for controlling desert by anatropal grass vegetation includes such steps as digging furrows by 15-18 cm of depth and 8-50 cm of space between furrows, binding 6-9 roots of anatropal grass into a sheaf, planting the sheaves in the furrows one by one, and spray irrigation. The root system of anatropal grass appears as net, so it can fixate sand. Its leaves can cover on the sand to prevent it from being brown away by wind.

Description

A kind of utilization vegetation of falling the sward is administered the method for sand damage

The present invention relates to the ecological environmental protection technical field, specifically a kind of utilization vegetation of falling the sward is administered the method for sand damage.

Up to now, human in kind of grass ruling by law reason sand damage, also do not find a kind of best grass seeds.Two kinds of selected in the present northwest-north-northeast China networks of shelterbelts construction of China sand control grass seeds are rustling sound grass and red building, though these two kinds of grass drought-resistant abilities are strong, in the desert of arid, can indomitablely survive, but shortcoming is that their root system is undeveloped, and branches and leaves are not attached to ground, and one to winter, the grass dead leaf falls, run into the wind more than 4 grades, loose sand still moves with the wind, and regulation effect is undesirable.

The purpose of this invention is to provide a kind of utilization well developed root system of falling the sward, branches and leaves are attached to ground and make ground vegetationization administer the method for sand damage.

The object of the present invention is achieved like this:

A kind of utilization vegetation of falling the sward is administered the method for sand damage, and it may further comprise the steps:

A, the root of falling the sward that will cultivate are one by 6～9 and tie that it is standby to transport to the sand control location;

B, in the place of having been desertified, leaving with plough is 15～18 centimetres capable ditch deeply, capable ditch spacing is 8～50 centimetres; The root of falling the sward that tied one is planted in the ditch of entering a profession suffering a ground, and will the root of falling sward pine;

C, the root of falling the sward that kind is gone into bury, leveling row ditch, and sprinkling irrigation is watered, and pouring in per 5～7 days is once;

D, kind are implanted with down the local permanent ban of sward and herd.

The present invention compared with prior art has following characteristics:

1, falling the root of sward is the ring shape, and during every root section length to 3～4 centimetres, root eye place bears sprouting again, goes out sand and comes into leaves, so go round and begin again, multiply without ceasely, plant 10 square centimeters the sward that falls, under the normal condition, next year just can be bred nearly 1 square metre area, can reduce planting cost.

2, the branches and leaves of falling the sward are long is attached to ground after certain density, winter marcescence leaf, the sand under the branches and leaves is covered, wind can not blow, thereby has the effect that yet can administer sand damage winter.

3, the emphasis of falling sward growth is a root system, in the yellow sand of moisture abundance, the root system fertility of this grass is tens times of other grass, it deep-rooted root system indentingly to below the face of land about 20 centimetres around radiation, thereby form network in loose yellow sand, when strong wind swept, the root system as the tangled skein of jute the yellow sand net therein, be fixed up, enlarged the sand control effect.

4, falling the network-like root system of sward has the function of retaining again concurrently, and root system water absorbing capacity in yellow sand is strong especially, and after moisture was on every side conserved by it, the sand blade of grass under wet, and wind can only blow off to be done huskyly, and the sand that wets can not scraped, and greatly reduces sand damage.

Embodiment 1

To administer 1 year time limit is example, and in the place of having been desertified, leaving with plough is 15～18 centimetres capable ditch deeply, and capable ditch spacing is 8～10 centimetres; The root of falling the sward that tied one is planted in the ditch of entering a profession suffering a ground, and will the root of falling sward pine, bury planting the root of falling the sward of going into then, leveling row ditch, sprinkling irrigation is watered, and waters once in per 5～7 days; The local permanent ban that is implanted with down sward in kind is herded.

Embodiment 2

To administer the time limit is example more than 3 years, in the place of having been desertified, leaving with plough is 15～18 centimetres capable ditch deeply, row ditch spacing is 30～50 centimetres, the root of falling the sward one that has tied planted in the ditch of entering a profession suffering a ground, and will the root of falling sward pine handle, bury planting the root of falling the sward of going into then, leveling row ditch, sprinkling irrigation is watered, and pouring in per 5～7 days is once; The local permanent ban that is implanted with down sward in kind is herded.

Claims (1)

1, a kind of utilization vegetation of falling sward method of administering the desert is characterized in that it may further comprise the steps:

A, the root of falling the sward that will cultivate are one by 6～9 and tie that it is standby to transport to the sand control location;

B, in the place of having been desertified, leaving with plough is 15～18 centimetres capable ditch deeply, capable ditch spacing is 8～50 centimetres; The root of falling the sward that tied one is planted in the ditch of entering a profession suffering a ground, and will the root of falling sward pine;

C, the root of falling the sward that kind is gone into bury, leveling row ditch, and sprinkling irrigation is watered, and pouring in per 5～7 days is once;

D, kind are implanted with down the local permanent ban of sward and herd.
