Problems solved by technology

Based on rain-fed conditions, there are deficiencies of insufficient rainfall, slow plant growth, and insufficient amount of grazing; and based on irrigation conditions, the cost of improving to mowed pastures is relatively high (such as the cost of equipment required for high-frequency water delivery, water consumption, etc.) cost, required labor cost), so it is not suitable for large-scale promotion in grassland areas

preparation example Construction

[0075] Among the present invention, the preparation method of soil conditioner comprises the following steps:

[0076] Step 1), add a set amount of humic substances, plant organic materials, ore powder, ammonium salt and potassium salt into the organic material liquid, and accumulate and ferment for 3-5 days;

[0077] Step 2), adding the microbial bacterial liquid and the algae-containing carrier into the system of step 1), mixing and stirring to obtain the pre-mixed material;

[0078] Step 3), before using in the soil, the coated grass seeds are mixed with the pre-mixed material to obtain a soil conditioner.

[0079] In step 3), the preparation step of coated grass seed specifically includes:

[0080] Step 3-1), adding water at a temperature of 85-95°C to the starch, and continuously stirring to obtain a starch solution with a starch mass concentration of 4-6%;

[0081] Step 3-2), mixing the grass seeds with the starch solution whose weight is 4-5 times, and drying in the s...

Embodiment 1

[0087] Embodiment 1 Flood accumulation and reuse

[0088] Flood collection: explore the approximate flow route of the flood near the exit of the mountain, build an arc-shaped diversion channel at the exit of the snowmelt flood along the flow path, and build a curved diversion channel with a central expansion on one side, and a straight-line diversion channel a little farther from the exit Connect the arc-shaped diversion channel to guide the flood to the dry area of ​​the grassland. At the same time, the diversion channel is opened in a slope shape, the upstream terrain is high, and the downstream terrain is low. The obtuse angle of the head is 160°, and the T-shaped dam is designed to match the slope to reduce sediment deposition;

[0089] Flood diversion: build 10 diversion canals in the arid area of ​​the grassland to branch diversion canals. The length of the diversion canals is 50-100 kilometers. Beyond the end of the diversion channel or aligned with the end of the div...

Embodiment 2

[0092] The preparation of embodiment 2 soil conditioners

[0093] The soil improver comprises the following components by weight: 500 parts by weight of organic material liquid; 40 parts by weight of humus, 50 parts by weight of humus; actinomycetes, nitrogen-fixing bacteria, Bacillus subtilis, yeast, Bacillus megaterium, sulfuric acid Salt-reducing bacteria (all bacteria are prepared in equal parts, the number per gram is about 4*10 8 ) 24 parts by weight in total; 20 parts by weight of zeolite powder, 40 parts by weight of vermiculite powder; 80 parts by weight of peat, 130 parts by weight of plant straw powder, 40 parts by weight of wood chips; 10 parts by weight of ammonium phosphate; 10 parts by weight of potassium tripolyphosphate; There are 12 parts by weight of the superabsorbent resin of Synechococcus, Pseudosyndiococcus, Lethiaceae and Nostoc; 15 parts by weight of coated grass seeds (Poa annua cold grass seeds), and 1 part by weight is 250g.

Abstract

The invention relates to a method for improving the alpine meadow grassland into a mowed grassland. Aiming at the problem of drought and water shortage, the method provides that by guiding (seasonal snowmelt) floods and purifying the floods, the purified water is used for alpine Water supply for meadows and grasslands; in view of the lack of soil nutrients, it is adjusted by applying soil improvers, which include biogas slurry, humic substances, microbial liquid, ore powder, plant organic materials, ammonium salts, potassium salts, Containing algae carrier, integrating improvement and ecological maintenance, can realize short-term fertilization and long-term support of plants, and through specific compatibility, it can promote rapid germination and rooting of grass seeds, and achieve the repair effect in the shortest possible time.

Description

technical field [0001] The invention relates to the field of grassland management, in particular to a method for improving alpine meadows in Qilian Mountains to mowed grasslands. Background technique [0002] There are all kinds of natural grass in our country 4×10 8 hm 2 , accounting for 41.7% of the country's land area, is one of the countries with the most grassland resources in the world. Natural vegetation types such as alpine meadows and alpine marsh grasslands are widely distributed in the Qilian Mountains, among which alpine meadows are the main natural grasslands in the Qilian Mountains and are also the main grazing pastures. Under the background of global climate change and the strong drive of human factors, the alpine meadow ecosystem structure tends to be simplified and its function is fragile. There are various factors of alpine meadow grassland degradation, including natural factors (such as drought, wind erosion, pests and rodents, etc.) and human factors (...
