Embodiment 1

[0037] The soil layer thickness of the selected black soil slope is more than 10cm, and the slope is 25-30 degrees. What this embodiment adopts is sowing.

[0038] S1, rodent control;

[0039] In winter, rodent infestation is prevented and controlled by using the biological control method of adding botulinum toxin bait.

[0040] S2, pre-processing;

[0041] Before planting, lightly plow and lightly harrow the black soil slope, and fertilize after lightly harrowing. Specifically, fertilization is 100 kg of diammonium phosphate and 400 kg of sheep manure per hectare.

[0042] S3, selection;

[0043] The selected rhizome-type grass species is Qinghai meadowgrass bluegrass, and the grazing-tolerant grass species is Maibingrass.

[0044] S4, seeding;

[0045] What present embodiment adopted is sowing, therefore, the sowing rate of rhizome type grass seed is 7.5kg / hm 2 , the sowing rate of grazing-tolerant grass species is 15kg / hm 2 .

[0046] S5, post-processing;

[0047] ...

Embodiment 2

[0050] The thickness of the soil layer of the selected black soil slope is 5cm-10cm, and the slope is more than 30 degrees. What this embodiment adopts is drill seeding.

[0051] S1, rodent control;

[0052] In winter, the biological control method of using botulinum toxin granules is used to prevent and control rodent infestation.

[0053] S2, pre-processing;

[0054] Before planting, carry out shallow plowing on the black soil slope, set up ridges and light harrows in the box, and fertilize after light harrowing. Specifically, fertilization was 300 kg of diammonium phosphate per hectare.

[0055] S3, selection;

[0056] The selected rhizome-type grass species is Qinghai meadowgrass bluegrass, and the grazing-tolerant grass species is Maibingrass.

[0057] S4, seeding;

[0058] What present embodiment adopted is sowing in drills, therefore, the sowing amount of rhizome type grass seed is 5.625kg / hm 2 , the sowing rate of grazing-tolerant grass species is 7.5kg / hm 2 . ...

Embodiment 3

[0063] The thickness of the soil layer of the selected black soil slope is 15cm, and the slope is 35 degrees. What the present embodiment adopted is broadcasting.

[0064] S1, rodent control;

[0065] In winter, rodent infestation is prevented and controlled by using the biological control method of adding botulinum toxin bait.

[0066] S2, pre-processing;

[0067] Before planting, lightly plow and lightly harrow the black soil slope, and fertilize after lightly harrowing. Specifically, fertilization is to apply 1200kg of sheep board manure per hectare.

[0068] S3, selection;

[0069] The selected rhizome-type grass species is Qinghai meadowgrass bluegrass, and the grazing-tolerant grass species is Maibingrass.

[0070] S4, seeding;

[0071] What present embodiment adopted is sowing, therefore, the sowing rate of rhizome type grass seed is 11.25kg / hm 2 , the sowing rate of grazing-tolerant grass species is 22.5kg / hm 2 .

[0072] S5, post-processing;

[0073] After th...

Abstract

The invention relates to the field of revegetation, in particular to a revegetation method of a black-soil slope. The method includes: sowing rhizome type grass seeds and grazing-resistant grass seedson the black-soil slope in a mixed manner, covering with non-woven fabric, and fencing to ban grazing. By the method, grassland quality can be increased evidently, revegetation of the black-soil slope of the Qinghai-Tibet Plateau can be achieved conveniently and favorably, and evident ecological economy and social benefits of grassland can be achieved.

Description

technical field [0001] The invention relates to the field of vegetation restoration, in particular to a method for rebuilding vegetation on black soil slopes. Background technique [0002] The Qinghai-Tibet Plateau is called "the third level in the world", with a unique geographical environment and special climatic conditions. The grassland ecosystem is dominated by alpine meadows. In recent years, under the joint influence of human society, production and management activities and global climate change, the structure and function process of alpine meadow ecosystem on the Qinghai-Tibet Plateau have undergone irreversible changes, the quality of grassland (including plants and soil) has declined, productivity, The economic potential and service functions are reduced, the ecological environment is deteriorated, the biodiversity and its complexity are reduced, the service functions and stability of the ecosystem are gradually lost, and the grassland ecological environment is se...
