The development of green agriculture must first solve the problem of soil pollution. Common problems in soil include: soil compaction, imbalance of mineral nutrient ratio, low organic matter content, shallow farming layer, soil acidification, soil salinization, soil pollution and so on. To make the soil suitable for the growth of crop roots, it is necessary to improve the physical properties of the soil. Increase the organic matter content of the soil, make the soil aggregate structure more, and less harmful elements in the soil.
Organic fertilizer is made of animal and plant residues, after being fermented in a high-temperature process, it eliminates toxic and harmful substances. It is rich in a large amount of organic substances, including: a variety of organic acids, peptides, and nitrogen, phosphorus, and potassium. The rich nutrients. It is a green fertilizer that is beneficial to crops and soil.
Soil fertility and soil utilization efficiency are two key factors to increase crop yields. Healthy soil is a necessary condition for high crop yields. Since the reform and opening up, with the changes in my country’s agricultural economic situation, large amounts of chemical fertilizers and pesticides have indeed made a huge contribution to the increase in food production, but at the same time, soil quality is also deteriorating, which is mainly manifested in the following three characteristics:
1. The soil plow layer becomes thinner. Soil compaction problems are common.
2. The overall content of soil organic matter is low.
3. The acid-base is very serious.
The benefits of applying organic fertilizer to the soil:
1. Organic fertilizer contains a variety of nutrient elements, which is conducive to the balance of soil nutrient ratio, is conducive to the absorption and utilization of soil nutrients by crops, and prevents soil nutrient imbalance. It can promote the growth of crop roots and the absorption of nutrients.
2. Organic fertilizer contains a large amount of organic matter, which is the food for various microorganisms in the soil. The more organic matter content, the better the physical properties of the soil, the more fertile the soil, the stronger the ability to retain soil, water, and fertilizer, the better the aeration performance, and the better the root growth of crops.
3. The use of chemical fertilizers and organic fertilizers can improve the buffering capacity of the soil, effectively adjust the acidity and alkalinity of the soil, so that the acidity of the soil will not increase. The mixed use of organic fertilizer and chemical fertilizer can complement each other, meet the nutrient needs of crops in various growth periods, and improve the effectiveness of nutrients.
The raw material resources of organic fertilizer are abundant, mainly as follows:
1. Animal manure: such as chickens, pigs, ducks, cattle, sheep, horses, rabbits, etc., animal residues such as fish meal, bone meal, feathers, fur, silkworm manure, biogas digesters, etc.
2. Agricultural waste: crop straw, rattan, soybean meal, rapeseed meal, cottonseed meal, loofah meal, yeast powder, mushroom residue, etc.
3. Industrial waste: distillers grains, vinegar residue, cassava residue, filter mud, medicine residue, furfural residue, etc.
4. Municipal sludge: river mud, sludge, ditch mud, sea mud, lake mud, humic acid, turf, lignite, sludge, fly ash, etc.
5. Household waste: kitchen waste, etc.
6. Refined or extracts: seaweed extract, fish extract, etc.
Introduction to the main equipment of the organic fertilizer production line:
1. Compost machine: trough type turning machine, crawler type turning machine, chain plate turning and throwing machine
2. Fertilizer crusher: semi-wet material crusher, vertical crusher
3. Fertilizer mixer: horizontal mixer, pan mixer
4. Compost screening equipment: drum screening machine
5. Fertilizer granulator: stirring tooth granulator, disc granulator, extrusion granulator, drum granulator
6. Dryer equipment: drum dryer
7. Cooling machine equipment: drum cooler
8. Production supporting equipment: automatic batching machine, forklift silo, automatic packaging machine, inclined screen dehydrator
