Problems solved by technology

Artificial fertilization has become a commonly used grassland improvement measure. However, excessive fertilization will cause soil compaction, which is effective for pasture growth in the short term, but it is not good for long-term excessive use.

preparation example Construction

[0090] Among the present invention, the preparation method of soil conditioner comprises the following steps:

[0091] Step 1), adding a set amount of humic substances, plant organic materials, ore powder, ammonium salt and potassium salt into the organic material liquid, and fermenting at 40-60°C for 3-5 days;

[0092] In step 2), the microbial bacterial liquid and the algae-containing carrier are added to the system in step 1), and mixed and stirred to obtain a soil conditioner.

[0093] The application method of the soil improver in the present invention is: spray the soil improver on the area to be restored, then no-till sowing, sow the coated grass seeds or grass seeds in the environment containing the soil improver, cover the soil, and the grass seeds germinate and grow.

[0094] The present invention aims at the specific problems faced by the establishment of high-quality forage grass in meadows and grasslands, such as rodent damage and nutrient deficiency, and provides...

Embodiment 1

[0139] In the study area of ​​the Jinqiang River Valley in the East Qilian Mountains (37°11'-37°14' north latitude, 102°19'-102°33' east longitude), the mildly degraded, moderately degraded, and heavily degraded areas were selected, respectively. Carry out targeted ecological restoration:

[0140] Mildly degraded grassland: "rat pest control + grazing prohibition and enclosure + breeding" mode;

[0141] Moderately degraded grassland: "rat pest control + grazing prohibition and enclosure + increasing breeding + no-tillage and supplementary sowing of suitable pasture" mode;

[0142] Severely degraded grassland: "rat pest control + grazing ban and enclosure + breeding + vegetation reconstruction" model.

[0143] Wherein, the method for the prevention and control of rodent damage comprises the combination of adopting D-type botulinum toxin rodenticide prevention and control and the biological rodenticide; For rodenticide with a concentration of 2.5‰~5‰, mix grass seeds 14 times ...

Embodiment 2

[0149] The preparation of embodiment 2 soil conditioners

[0150] The soil conditioner includes the following components by weight: 2000 parts of organic material liquid; 45 parts of humus, 50 parts of humus; actinomycetes, nitrogen-fixing bacteria, Bacillus subtilis, yeast, Bacillus megaterium, sulfate-reducing bacteria (All bacteria are prepared in equal parts, the number per gram is about 4*10 8 ) 24 parts in total; 20 parts of zeolite powder, 40 parts of vermiculite powder; 80 parts of peat, 130 parts of plant straw powder, 40 parts of wood chips; 10 parts of ammonium phosphate; 10 parts of potassium tripolyphosphate; 12 parts of the superabsorbent resin of algae, leptocystis and nostoc.

[0151] The preparation method of soil conditioner comprises the following steps:

[0152] Step 1), adding the above-mentioned set amount of humus, leaf humus, peat, plant straw powder, sawdust, zeolite powder, vermiculite powder, ammonium salt and potassium salt into the organic materi...

Abstract

The invention relates to a method for planting high-quality forage grass in meadow grassland by applying a no-tillage method. A targeted repair scheme is designed according to different degradation degrees of the meadow grassland, and the problem that the soil nutrients are insufficient is solved by applying a soil conditioner. A high-efficiency root cutting device capable of cutting roots along aplurality of directions is researched and developed according to a soil hardening problem caused by perennial growth of perennial gramineous plants. The invention provides the improvement method, wherein the current situation of the meadow grassland is comprehensively considered, restriction factors of plant growth are reduced or relieved, the cost is low, and the effect is remarkable, so that ecological restoration of the meadow grassland is achieved, and sustainable and healthy development of animal husbandry of the grassland is maintained.

Description

technical field [0001] The invention relates to the field of grassland management, in particular to a method for using no-tillage method to build high-quality forage grass in meadows and grasslands. Background technique [0002] Under the background of global climate change and strongly driven by human factors, the structure of meadow steppe ecosystem tends to be simplified and its function is fragile. There are various factors for the degradation of meadow grassland, including natural factors (such as drought, wind erosion, pests and rodents, etc.) and human factors (such as overgrazing, heavy mowing, overcultivation, digging, etc.). In recent years, due to the dual effects of man-made and natural factors, the grasslands in some areas of the Qilian Mountains have been severely degraded, and some areas have even shown a trend of desertification and desertification. Grassland degradation is becoming more and more serious, which directly threatens the sustainable, stable and ...
