[0052] (5) Gravel reinforcement and freshwater salt washing measures are used after extreme rainfall.

[0053] As an implementation method in this embodiment, the mushroom residue is decomposed mushroom residue, and the particle size of the mushroom residue is not greater than 2 mm.

[0054] Specifically, the mushroom residue is decomposed mushroom residue, which is crushed to a particle size of ≤2 mm.

[0055] As an implementation method in this embodiment, the coverage area of ​​the gravel layer is 80% to 85% of the fungus slag layer, and mechanically compacted gravel ridges are formed on the edges of both sides of the gravel layer.

[0056] Specifically, the gravel layer is laid on the surface of the mushroom residue, and gravel ridges are formed on both sides of the edges, with a width of 10 cm and a thickness of 2 to 3 cm, and are mechanically compacted.

[0059] As an implementation method in this embodiment, the agricultural machinery includes a rotary tillage-slag laying machine, a sowing-compacting machine and a gravel laying machine;

[0060] The rotary tillage-slag laying integrated machine is used to synchronously perform soil rotary tillage and mushroom slag laying, the rotary tillage depth is 14 cm, and the laying thickness of mushroom slag or fly ash is 7 cm;

[0061] The sowing and compacting machine is used to sow the switchgrass residue seed mixture and compact the soil, the compaction degree is equivalent to that of an 80 kg adult, and is equipped with a ground harrow device to comb the soil to a depth of 1.5 cm to 2.0 cm;

[0087] Agricultural machinery: rotary tillage-slag spreading machine, seeding-compacting machine, gravel paving machine.

[0088] The detailed steps include:

[0089] 1. Land preparation

[0090] The rotary tillage depth is 14 cm, and after leveling, a mushroom residue layer (thickness ≥ 5 cm) is laid;

[0091] In extremely heavy saline-alkali land, drainage ditches (depth ≥ 20 cm) and ponds (water storage capacity ≥ 50m 3 ).

[0092] 2. Improvement and planting

[0093] The gravel laying machine covers the surface of the mushroom residue, and a gravel ridge is formed on the edge;

[0094] The seeding-compacting machine sows the switchgrass residue seed mixture, and the compaction degree is equivalent to 80kg of compaction; fresh water ≥50mm is irrigated within 24 hours after planting.

[0095] 3. Disaster response

[0096] After heavy rain, add gravel layer and wash salt with fresh water (irrigation ≥5cm).

[0097] Implementation cases include:

[0098] Implementation case 1: Super heavy saline-alkali land (salt content 6.5%)

[0099] Steps: After rotary tillage, lay a 5cm layer of mushroom residue + gravel and build drainage ditches;

[0100] Results: The surface salinity dropped from 6.5% to 1.3%, and the survival rate of switchgrass was 78%.

[0101] Implementation case 2: Severe saline-alkali land (salt content 3.0%)

[0102] Steps: 4cm of mushroom residue + gravel layer, omitting the pond system;

[0103] Results: Salinity dropped to 0.8% and the survival rate was 85%.

[0104] Implementation case 3: mechanized planting trial

[0105] Steps: Use special agricultural machinery to complete rotary tillage, sowing and gravel laying;

[0106] Result: Operation efficiency increased by 3 times and cost reduced by 42%.

[0107] Comparative Example:

[0108] Comparative Example 1: Pure fungus residue improvement (without crushed stone)

[0109] Results: After the heavy rain, 50% of the fungus residue was lost and the salinity rose to 4.5%.

[0110] Comparative Example 2: Traditional artificial planting

[0111] Results: The survival rate was 65% and the cost was 2.5 times that of the mechanized solution.

[0112] Comparative Example 3: No drainage system

[0113] Result: Waterlogging resulted in salinity convergence and the survival rate dropped to 40%.

[0114] Comparative Example 4: Fly ash alone for covering

[0115] Results: The salinity dropped by only 30%, and the emergence rate was 50%.

[0116] Comparative Example 5: Direct planting without rotary tillage

[0117] Results: The soil was compacted, the root system of switchgrass was poorly developed, and the mortality rate was 60%.

[0118] Based on this, the present invention significantly improves the planting efficiency and survival rate of switchgrass in saline-alkali land through the coordinated improvement of mushroom residue and crushed stone, optimization of water conservancy projects and mechanized operations, has significant ecological and economic benefits, and is suitable for large-scale promotion.
