Problems solved by technology

Soil acidification not only destroys soil properties, but also promotes the release, migration, or enhancement of toxicity of some toxic and harmful pollutants in the soil, reduces soil organisms such as microorganisms and earthworms, and accelerates the loss of soil nutrients. Agricultural Cultivation Value
At the same time, the production of chemical fertilizers consumes energy; emits greenhouse gases; and the pollution of the three wastes is very serious

Embodiment 1

[0081] The method for high-yield cultivation in spring of embodiment 1-Sudangrass

[0082] Take spring cultivation in the middle and lower reaches of the Yangtze River in China as an example.

[0083] Specific steps are as follows:

[0084] 1. Before December of the first year, select areas with better water and fertilizer conditions, and plow to a depth of 20-25cm.

[0085] 2. After April of the second year, when the ground temperature reaches above 10°C, choose a sunny day to intensively cultivate the field, rake the topsoil, and level the ground.

[0086] 3. In order to improve the germination rate of seeds, dry the seeds for 1-2 days within 1 month before sowing.

[0087] 4. When the ground temperature is stable above 10°C, excavate planting holes with a length and width of 15cmх15cm and a depth of 10cm according to the spacing between plants and rows of 20-30cmх20-30cm; apply 0.5-1kg of organic fertilizer to each planting hole, and then cover 1 ~2cm fine soil.

Embodiment 2

[0098] Embodiment 2 - the method for fast-growing plant carbon storage profiles forming

[0099] Taking reed and grass as examples, the specific steps are as follows:

[0100] 1. Dry the harvested fast-growing plants naturally, and control the moisture content within 20%.

[0101] 2. Use a pulverizer to crush the fast-growing plants into 1-10mm long particles; the stems and leaves of the herbaceous plants are more flexible after drying, and the raw materials must be cut in the pulverizer before they can be pulverized. The pulverizer with the functions of cutting, crushing and dust removal is preferred, and the crushing and dust removal can be completed at one time.

[0102] 3. Dry the crushed granular raw materials; the screw extrusion molding machine has high requirements for moisture, and the moisture content of the granular raw materials is controlled at 10-15%; the mechanical compression molding machine has looser requirements for the moisture content of the granular ra...

Embodiment 3

[0105] Embodiment 3-fast-growing plant or its carbon storage profile composting device and method

[0106] see figure 1 , the device and method for composting fast-growing plants or their carbon storage profiles include a plant pulverizer 3, plant particle conveyor belts 4 and 7, a composting workshop 8, a deodorizing tower 44, a dehydration and filtration tower 48, a desulfurization and deoxidation tower 52, and a gas separation Device 56, flame arrester 60, burner 62, ammonia water synthesis tower 66, ammonia water storage tower 71, the first fermenting tank 30, the second fermenting tank 18, pulverizing pump 24, strain bucket 83; Described plant pulverizer 3 Link to each other with plant particle conveyor belt 4; Described plant particle conveyor belt 7 links to each other with hopper 78; Compost fermentation tank 29 is provided in described composting workshop 8; Turnover machine 13 is provided on described compost fermentation tank 29; Fermentation tank 29 is provided ...

Abstract

The invention discloses a device and method for planting fast-growing plants and replacing chemical fertilizers with plant composts. The plant composts replace the fossil energy sources in the chemical fertilizer production process to achieve negative growth of atmospheric greenhouse gases, adjust the greenhouse effect, inhibit the formation of hazes, solve the related environmental problems, improve the soil structure and improve the soil fertility. The method comprises the following steps: (1) planting and / or cultivating fast-growing plants in the selected land area or water body area; (2) harvesting when the fast-growing plants grow to an appropriate height; (3) performing drying on the harvested fast-growing plants, and preferably performing natural drying; (4) processing the dried fast-growing plants into carbon-storage sections; (5) keeping the molded plant carbon-storage sections under sealed conditions; (6) processing the fast-growing plants and carbon-storage sections thereof into organic fertilizers, and converting nitrogen-containing gases generated during the process into nitrogen-containing fertilizers (ammonia water).

Description

technical field [0001] The invention relates to a device and a method for planting fast-growing plants and replacing chemical fertilizers with plant compost, belonging to the field of chemical industry. Background technique [0002] my country is one of the countries that use the largest amount of chemical fertilizers and pesticides in the world, and the utilization rate of chemical fertilizers is low, with an average utilization rate of only 30% to 35%. 51% of nitrogen. Chemical fertilizers not only pollute farmland soil, but also seriously pollute water bodies, the atmosphere, and organisms, causing serious harm to human health. The nitrate content in vegetables with excessive nitrogen application is 20-40 times the normal situation. After humans or livestock eat plants with high nitrate content, nitrate reacts with various amines in the body to produce amine nitrite, and at the same time, nitrite is easily combined with iron ions in heme, resulting in methemoglobin leuke...
