Embodiment 1

[0022] Step 1: Put the compost into a mesh bag with a mesh diameter of 0.15mm;

[0023] Step 2: Add water to the container and place the vent pipe at the bottom of the container, 1m 3 The aeration rate of the water is 0.2L / h, and the air is ventilated for 30 minutes. After removing the chlorine, add molasses, seaweed powder and humic acid with a mass ratio of 1:4:3, and then put the net bag filled with compost in step 1 into the water , The mass ratio of compost to water is 1:20; the total mass of molasses, seaweed powder and humic acid added is 2% of the compost mass;

[0024] Step 3: Avoid direct exposure to strong light during the extraction and fermentation process, keep the solution aerated, and control the outside temperature at 25-30°C. After 24 hours, a compost tea with improved soil compaction is prepared.

[0025] The described compost selection meets the requirements of organic fertilizer NY525-2011 and bio-organic fertilizer standard NY 884-2004, and the biological indica...

Embodiment 2

[0029] Step 1: Put the compost into a mesh bag with a mesh diameter of 0.15mm;

[0030] Step 2: Add water to the container and place the vent pipe at the bottom of the container, 1m 3 The aeration rate of the water is 0.2L / h, and the air is ventilated for 30 minutes. After removing the chlorine, add molasses, seaweed powder and humic acid with a mass ratio of 1:3:2, and then put the net bag filled with compost in step 1 into the water , The mass ratio of compost to water is 1:10; the total mass of molasses, seaweed powder and humic acid added is 3% of the compost mass;

[0031] Step 3: Avoid direct exposure to strong light during the extraction and fermentation process, keep the solution aerated, and control the outside temperature at 25-30°C. After 36 hours, a compost tea with improved soil compaction is prepared.

[0032] The described compost selection meets the requirements of organic fertilizer NY525-2011 and bio-organic fertilizer standard NY 884-2004, and the biological indica...

Embodiment 3

[0038] Step 1: Put the compost into a mesh bag with a mesh diameter of 0.50mm;

[0039] Step 2: Add water to the container and place the vent pipe at the bottom of the container, 1m 3 The aeration rate of the water is 0.5L / h, and the air is ventilated for 30 minutes. After removing the chlorine, add molasses, seaweed powder and humic acid in a mass ratio of 1:2:2, and then put the net bag filled with compost in step 1 into the water , The mass ratio of compost to water is 1:15; the total mass of molasses, seaweed powder and humic acid is 1% of the mass of compost;

[0040] Step 3: Avoid direct exposure to strong light during the extraction and fermentation process, keep the solution aerated, and control the outside temperature at 25-30°C. After 48 hours, a compost tea with improved soil compaction is prepared.

[0041] The described compost selection meets the requirements of organic fertilizer NY525-2011 and bio-organic fertilizer standard NY 884-2004, and the biological indicators ...

Abstract

The invention discloses a compost tea for improving the soil hardness and a preparation method thereof, belonging to the technical field of soil improvement. The preparation method of the compost tea suitable for improving the hardness soil comprises three parts: material selection, preparation process and quality index selection. The applying method of the compost tea comprises the step of selecting parameters of applying condition, applying time and applying amount. The preparation method of the compost tea has the advantages of easily obtained materials, lower cost, simple preparation process and simple applying method. The preparation of the improved hardened soil of the compost tea has the advantages of high efficiency and short time, and the crumb structure of the hardened soil is remarkably improved 40-50 days after the application of the compost tea. Chemically synthesized substances are not needed in the materials, and the compost tea solution prepared is pollution-free to the environment, thereby conforming to the need of agricultural sustainable development.

Description

Technical field [0001] The invention belongs to the technical field of soil improvement, and particularly relates to a compost tea for improving soil compaction and a preparation method thereof. Background technique [0002] (1) Soil compaction is an important problem faced in the process of sustainable agricultural development. [0003] As countries around the world pay more and more attention to the sustainable development of agriculture, they have put forward higher requirements for the sustainability of soil production capacity. Especially when my country has a large population, little arable land, and faces a severe situation of food security, how to ensure the sustainable production capacity of the soil is particularly important. Soil compaction is one of the important manifestations of soil degradation, especially subsurface soil compaction, which restricts the growth of plant roots underground. In the middle and late stages of plant growth, such as low rainfall and ...
