Problems solved by technology

On the one hand, these rot-promoting agents mainly use nitrogen-containing compounds such as urea to adjust the carbon-to-nitrogen ratio; Excessive use of compounds may easily cause non-point source pollution, etc. The latter is expensive, the conditions for bacterial culture are harsh, and the application is more complicated, making it difficult to promote the use of large areas

Embodiment 1

[0023] Embodiment 1: a kind of straw rotting method, such as figure 1 shown, including the following steps:

[0024] S1: Mechanized harvesting after the rice is mature, crushing the straw to 10-15 cm, and throwing it on the ground;

[0025] S2. Cut the leaf-eating grass to a width of 0.5 cm-3 cm, and spread it evenly on the ground;

[0026] S3, turn over the ground, just turn over the straw and leaf-eating grass to cover the soil;

[0027] S4, release water after 24 hours to 48 hours of flooding, and keep the soil moist for 10 days.

[0028] In the S1-S2, the straw organic matter is 89.5% (carbon is 34.61%), leaf-eating grass protein is 32.3% (nitrogen is 5.168%), and the amount of straw per mu is calculated as 0.6 tons based on 0.5 tons of rice and 1:1.2 ratio of rice to grass (dry basis), calculated according to the carbon-nitrogen ratio of 25:1, then add 290 kg of leaf-eating grass (dry basis) per mu, and calculate according to 80% moisture, then add about 1.5 tons / mu of...

Embodiment 2

[0031] Embodiment 2: a kind of straw rotting method, such as figure 2 shown, including the following steps:

[0032] S1: Mechanized harvesting is carried out after the rice is mature, and the straw is broken to 10-15 cm by the harvester and scattered on the ground;

[0033] S2. Cut the leaf-eating grass to a width of 0.5 cm-3 cm, and spread it evenly on the ground;

[0034] S3. Use a tractor to plow the ground, and turn over the straw and leaf-eating grass to cover the soil;

[0035] S4, release water after 24 hours to 48 hours of flooding, and keep the soil moist for 15 days.

[0036] In the S1-S2, the straw organic matter is 92% (carbon is 35.58%), leaf-eating grass protein is 33.6% (nitrogen is 5.376%), and the amount of straw per mu is calculated as 0.5 tons of rice and the ratio of rice to grass is 1:1.2 is 0.6 tons (dry basis), calculated according to the carbon-to-nitrogen ratio of 30:1, then add 136 kg of leaf-eating grass (dry basis) per mu, and calculate accordin...

Embodiment 3

[0039] Embodiment 3: a kind of straw rot promoting method, such as image 3 shown, including the following steps:

[0040] S1: Mechanized harvesting is carried out after the rice is mature, and the straw is broken to 10-15 cm by the harvester and scattered on the ground;

[0041] S2. Cut the leaf-eating grass to a width of 0.5 cm-3 cm, and spread it evenly on the ground;

[0042] S3. Use a tractor to plow the ground, and turn over the straw and leaf-eating grass to cover the soil;

[0043] S4, release water after flooding for 24-48 hours, and keep the soil moist for 12 days.

[0044] In the S1-S2, the straw organic matter is 87.2% (carbon is 33.72%), leaf-eating grass protein is 32% (nitrogen is 5.12%), and the amount of straw per mu is calculated as 0.5 tons of rice and the ratio of rice to grass is 1:1.2 is 0.6 tons (dry basis), based on the carbon-to-nitrogen ratio of 20:1, the addition of leaf-eating grass (dry basis) per acre is: 560 kg, calculated on the basis of 80% ...

Abstract

The invention relates to the technical field of crop straw efficient resource utilization, in particular to a straw decay promoting method. According to the straw decay promoting method, straw is taken as a raw material, rumex hanus is taken as a decay promoting auxiliary agent, the characteristics of high organic matter content of the straw and high protein content of the rumex hanus are combined to reach an optimal carbon-nitrogen ratio range (C/N is (20-35): 1) beneficial to straw decomposition, the number and activity of soil microorganisms are improved, the straw decomposition can be obviously promoted, and the straw degradation time can be shortened; the simultaneous degradation of the straw and the rumex hanus is also beneficial to the improvement of soil organic matters and soil nitrogen, the soil fertility is quickly improved, and the crop yield is improved; the rumex hanus is very easy to plant, the biomass is great (the yield per mu is 20-40 tons), and the protein content can reach 32% or above. Compared with traditional and existing straw decay promoting methods, the straw decay promoting method has the advantages of sufficient and stable raw material source of the decay promoting auxiliary agent, simplicity, wide adaptability, greenness, no pollution and facilitation of large-area popularization and demonstration.

Description

technical field [0001] The invention relates to the technical field of high-efficiency resource utilization of crop straws, in particular to a straw decay-promoting method. Background technique [0002] Crop straw contains huge nutrients and is an important energy and resource. China is a large agricultural country with abundant crop straw resources, and the annual output of crop straw can reach about 800 million tons. However, for a long time, as agricultural by-products, there have been a large number of discarding and burning problems, which will pollute the environment, affect human health, and lead to a huge waste of resources. Rice is my country's largest ration and the staple food of more than half of the country's population. In 2017, the planting area reached 453 million mu, and the resulting straw reached 224 million tons. How to achieve recycling of straw is an urgent problem to be solved. [0003] One of the very important ways of straw recycling is straw retu...
