Embodiment 1

[0023] A field ditch lining material based on crop stalks, comprising the following components in mass percentages: 1%-7% of straw, 80%-90% of soil, 0.02%-0.06% of microbial additives, and the rest is water.

[0024] The soil is one of sandy soil, clay soil or loam soil. The microbial additive is one or both of Arthrobacter or Bacillus subtilis, which can be selected according to climate conditions or soil characteristics. The straw is one of wheat straw, corn straw or rice straw.

[0025] It is worth noting that the total amount of microbial additives is 15-30g / mu.

[0026] A method for laying the above-mentioned field ditch lining material based on crop straws, comprising the following steps: crushing the straws into small sections with a length of 3-8 cm, wherein the amount of straws with a length greater than 5 cm accounts for 10%-35% of the total amount of straws, whichever For the soil in the ditch, measure the water content in the soil, calculate the added amount of w...

Embodiment 2

[0029] A field ditch lining material based on crop stalks, comprising the following components in mass percentages: 2%-6% of corn stalks, 80%-90% of loam soil, 0.03%-0.06% of Arthrobacter, and the rest is water.

Embodiment 3

[0031] A field ditch lining material based on crop stalks, comprising the following components in mass percentage: 5% of wheat straw, 80% of sandy soil, 0.05% of each of Arthrobacter and Bacillus subtilis, and the rest is water.

Abstract

Belonging to the technical field of agriculture, the invention discloses a crop straw based field ditch lining material, which comprises the following components by mass percentage: 1%-7% of straw, 80%-90% of soil, 0.02%-0.06% of a microbial additive, and the balance water. The invention also discloses a laying method of the crop straw based field ditch lining material, and the method includes: crushing straw into segments with a length of 3-8cm, taking soil from a ditch, mixing the substances evenly according to the mass percentage, then laying the evenly mixed mixture on the field ditch surface, conducting mechanical compaction to form a composite layer for lining protection of the field ditch. The field ditch lining material provided by the invention utilizes straw as the skeleton to fix the soil of the composite layer and prevent slope slump, and utilizes the characteristics of easy water absorption and a post-water absorption expansion coefficient greater than soil of straw to reduce the water permeability of the composite layer and reach a seepage-proofing effect.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a field ditch lining material based on crop stalks and a laying method thereof. Background technique [0002] Canal anti-seepage methods can be divided into two categories. The first category is to change the soil permeability of the original canal bed, which can be divided into physical mechanical methods and chemical methods. The former is to reduce the leakage by reducing the soil voids, which can be compacted, silted, wiped, etc.; the latter is to add chemical materials to enhance the impermeability of the soil in the canal bed; the second type is to set an anti-seepage layer, That is, the canal lining can be lined with various materials such as concrete and reinforced concrete, plastic film, stone masonry, bricklaying, asphalt, composite soil, cement soil and clay. After anti-seepage measures are adopted, the channel leakage loss can be reduced by 50% to 90%. Concrete li...
